Annealing-Induced Structural and Surface Evolution in Ti/TiO₂ Thin Films
type: item
description: This study investigates the influence of annealing temperature on the structural, compositional, and nanoscale morphological evolution of thermally oxidized Ti/TiO₂ thin films with a thickness of approximately 120 nm. Titanium films deposited by electron-beam evaporation were annealed in air over the temperature range of 100–500 °C and characterized using Raman spectroscopy, X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), and atomic force microscopy (AFM). Raman analysis revealed temperature-dependent variations in peak position, linewidth, and relative spectral contributions, indicating progressive structural reorganization and modification of the local vibrational environment during thermal treatment. Complementary XRD measurements supported the presence of annealing-induced structural evolution associated with anatase-, rutile-, and brookite-related contributions. The Raman linewidth exhibited a non-linear dependence on annealing temperature, reflecting variations in structural heterogeneity and local ordering. EDS analysis showed non-monotonic variations in the O/Ti atomic ratio, while AFM observations demonstrated a gradual transition from irregular surface morphologies toward more compact nanoscale structures with increasing annealing temperature. This evolution was accompanied by a systematic decrease in surface roughness (Rq) and a reduction in the lateral dimensions of surface features, indicating progressive nanoscale densification. The combined results demonstrate that thermal annealing induces interconnected structural and morphological modifications in Ti/TiO₂ thin films, highlighting the importance of correlating vibrational, compositional, and surface analyses for understanding thermally oxidized oxide systems.

title: Nano-biocomposites from Chitosan Nanoparticles and Tribulus terrestris-Mediated Silver Nanoparticles as Alternatives to 17α-Methyltestosterone for Enhancing Reproductive Performance in Male Nile Tilapia
description: This study evaluated and compared the effectiveness of Tribulus terrestris extract-mediated silver nanoparticles loaded onto a chitosan nanopolymer (TT/AgNPs/CsNPs) with synthetic testosterone (17α-methyltestosterone; MT) in enhancing the reproductive performance of male Nile tilapia (Oreochromis niloticus). A total of 75 fish (initial weight 60 ± 3.25 g) were randomly assigned to five experimental treatments (15 fish per group; three replicates of five fish each) and fed a basal diet containing 30% crude protein for 60 consecutive days. The treatments included: control group (CG, basal diet only), MT group (60 mg MT/kg diet), TT/AgNPs group (750 mg TT/AgNPs/kg diet), TT/AgNPs/CsNPs group (750 mg of TT/AgNPs/CsNPs per kg diet), and TT/AgNPs/CsNPs + MT group (750 mg nanocomposite + 20 mg MT/kg diet). Results revealed that the TT/AgNPs/CsNPs + MT group exhibited the most significant improvement in semen quality parameters, including sperm concentration (310x106/mL), motility (32%), and viability (89%), beside elevated serum testosterone (6.95ng/ml) and 11-ketotestosterone (3.15ng/mL) levels. Importantly, liver function indicators across all experimental groups remained within normal physiological ranges, confirming the biosafety of the nanoparticle supplementation. These findings suggest that nano-formulated T. terrestris offers a safe and effective alternative to synthetic androgens in aquaculture for improving male reproductive performance in aquaculture species.

Increased sensitivity in planar waveguide plasmonic nanobiosensores based on two-dimensional graphene-MoS2 multilayers
type: item
description: This paper investigates biosensors based on plasmonic nanostructures. A plasmonic sensor using planar optical waveguide consisting of graphene and metal oxide layers has been designed and simulated for detecting biomolecules such as DNA. Plasmonics, branch of photonics, underpins many biophotonic applications, especially biosensing. Proposed biosensor relies on surface plasmon resonance in hybrid graphene/MoS2 structure, enabling high-sensitivity detection. Sensing mechanism analyzes transmission spectrum of an electromagnetic wave launched into waveguide, which varies with refractive index changes of biomolecules near surface. Performance has been evaluated at 633 nm and for different light incidence angles. Effects of number and arrangement of graphene and MoS2 layers on resonance angle, sensitivity, full width at half maximum (FWHM), and figure of merit (FOM) have been studied. Results show that a single graphene layer with a single MoS2 layer yields optimal performance, with sensitivity of 193 deg/RIU and FOM of 16.6 RIU-¹. Minimum FWHM of 11.62° and transmission intensity Tmin of 0.02 have been obtained. Increasing layer numbers due to optical absorption and plasmonic damping leads to higher optical losses, broader resonance curve, and reduced FOM. Electromagnetic field distribution and sensor characteristics have been analyzed via resonance angle shifts, identifying optimal structure with highest sensitivity and FOM.

Mechanical Behavior and Durability of Nano TiO2–modified UHPC Reinforced with Recycled Steel Fibers under Corrosive Wastewater Environment
type: item
description: This study investigates the mechanical performance and sulfate durability of ultra-high-performance concrete (UHPC) modified with nano-TiO2 and reinforced with industrial steel fibers (I-SF) or tire-derived recycled steel fibers (R-SF). UHPC specimens were exposed for 28 days to water, 5% MgSO₄, and 10% MgSO₄ solutions, followed by compressive and direct tensile testing. Under water curing, fiber incorporation significantly enhanced compressive strength from 84.0 MPa (plain UHPC) to 135.6 MPa with 0.6% I-SF and 126.8 MPa with 0.6% R-SF. Tensile strength similarly increased from 6.5 MPa to 10.53 MPa and 8.84 MPa for 0.6% I-SF and R-SF, respectively. Severe sulfate exposure (10% MgSO₄) reduced compressive strength of the control mixture to 74.0 MPa, whereas fiber-reinforced mixtures retained substantially higher strengths, with lower relative degradation observed for R-SF (≈5–7%) compared to I-SF (≈10–12%). Nano- TiO2 improved matrix compactness and durability, with 0.4 wt.% identified as the optimal dosage for maximizing strength retention. Scanning electron microscopy confirmed enhanced C–S–H densification and improved interfacial stability, particularly in TiO2/R-SF composites. The findings demonstrate that integrating nano-modification with recycled steel fibers provides a durable and sustainable UHPC solution for sulfate-rich environments.

Synthesis of Calcium Hydroxide Nanoparticles via Hydrothermal Method: A Breakthrough in Paper Deacidification and Preservation
type: item
description: The preservation of paper-based cultural heritage object is often affected by acidic degradation, creating the urgency of developing investigating technique which is effective and sustainable for deacidification paper. For this research, Ca (OH)₂ nanoparticles were produced using the hydrothermal method by changing the temperature range from (90°C-120°C), and then further characterization was conducted regarding its morphological, structural, and functions properties. The hydrothermal method was found very useful and effective in the preparation of high crystallinity hexagonal phase-pure nanoparticles with controlled size and morphology. The observations regarding the effects of temperature were made by XRD, FTIR, UV, & SEM analysis. Among all the investigated conditions, nanoparticles synthesized at 110 °C exhibited ideal characteristics, including uniform particle size, enhanced crystallinity, and larger dispersion stability. Application of this study demonstrated that Ca (OH)₂ nanoparticles efficiently neutralized acidity in paper specimens, increasing pH from 3 (acidified) to 8 (treated) and maintaining stable neutral pH (~7) even after 60 days of ageing. This brings in notice both the immediate reactivity and long-term buffering capacity of the nanoparticles. When, compared to standard bulk alkaline agents, the hydrothermally synthesized Ca (OH)₂ nanoparticles provide deeper fibre penetration, higher reactivity, and sustainable synthesis adaptability, positioning them as a novel and effective tool for the conservation of paper-based artifacts. Overall, the results confirm the hydrothermal process as an extremely effective synthesis route and suggest promising opportunities for the wider application of Ca (OH)₂ nanoparticles in the conservation of diverse heritage substrates as well as in the development of eco-friendly nanocomposite.

Engineering PVA-Based Nanofibrous Mats Containing Pramipexole with Anti-Parkinsonian Effects: Fabrication, Characterization, and Pharmacological Study
type: item
description: Parkinson’s disease is a progressive neurodegenerative disorder that requires long-term pharmacotherapy; however, conventional oral administration of pramipexole is associated with fluctuating plasma levels and systemic side effects. In this study, a novel electrospun PVA-based nanofibrous transdermal patch containing pramipexole was developed to enable controlled drug delivery and improved therapeutic efficacy. Pramipexole-loaded PVA and PVA/PVP nanofibers were fabricated via electrospinning and subsequently cross-linked using glutaraldehyde vapor. The nanofibrous mats were characterized in terms of morphology, wettability, rheological behavior, drug release kinetics, and in vivo neuroprotective performance. Smooth and bead-free nanofibers were obtained, confirming suitable solution viscosity and electrospinnability. Water contact angle measurements demonstrated hydrophilic behavior, with contact angles of 33° for PVA, 71° for PVA/PVP, and 43° for cross-linked PVA/PVP/pramipexole nanofibers, indicating tunable surface wettability. In vitro release studies revealed an initial burst release of approximately 43% and 32% of pramipexole within 30 min for PVA and PVA/PVP nanofibers, respectively, followed by sustained release reaching ~52% and ~49% after 24 h. In contrast, cross-linked nanofibers exhibited significantly slower and more controlled drug release due to reduced polymer network permeability. Histopathological analysis of the substantia nigra region in a paraquat-induced Parkinson’s disease model demonstrated a marked reduction in neuronal degeneration in both systemic and transdermal pramipexole-treated groups compared to untreated animals.

title: Enhanced Electrostatic Control and Biosensing in a No Junction Gate all Around Hetero Dielectric Tunnel Field Effect Transistor (NJGAA-HTFET): A Nanoscale Study Through Analytical Modeling and TCAD Simulation
description: In the modern era of miniaturization, Tunnel Field Effect Transistor (TFET) is considered to be a dominant device for low-power applications due to its primary switching mechanism. The concept of TFETs is that quantum tunnelling across a barrier is regulated, whereas in conventional MOSFETs, the thermionic emission across a barrier is regulated. In this paper, the No Junction Gate All Around Hetero Dielectric Tunnel Field Effect Transistor (NJGAA-HTFET) is modelled at large drain voltage, even though the effect of drain voltages is less pronounced. Theoretical tests have proved that using the low-voltage TFETs in logic circuits instead of MOSFETs, will conserve significant amounts of electricity. Hence, this work presents the analytical modelling of the No Junction Gate All Around Hetero Dielectric Tunnel Field Effect Transistor, where surface potential profile, IDS VGS, and IDS VDS characteristics are analytically modelled using the Kane approach. A comparison of TCAD simulation and modeling under various device parameters, including gate oxide dielectric constant, channel lengths, and junction/junctionless structures, is conducted and further discussed to validate the model. The results of the Ion/Ioff ratio of the proposed device prove to be superior to those of conventional JLTFET devices. More specifically, the NJGAA-HDTFET is identified for use as a biosensor to detect various biomolecules.

Label-free Sensing of Thiamine, Pantothenic Acid and Pyridoxine Hydrosoluble Vitamins Using a Symmetric Photonic Heterostructure Resonator
type: item
description: This study presents a label-free biosensor based on a symmetric one-dimensional photonic heterostructure resonator for the refractometric detection of three water-soluble B-complex vitamins. By filling the defect cavity with vitamin solutions, the sensor generated distinct resonance shifts proportional to refractive-index changes, enabling precise molecular discrimination. Optimal performance was achieved at a 60° incidence angle under transverse-electric polarization, yielding ultra-high sensitivity (nearly 280 nm/RIU), a sharp resonance quality factor exceeding 2000, and a detection limit as low as 1.21×10⁻³ RIU, accompanied by a figure of merit greater than 800 surpassing conventional 1D photonic crystal biosensors. A strong polarization-dependent response was observed, with transverse-magnetic (TM) mode performance degrading at high angles due to Brewster’s effect, confirming TE polarization as the superior sensing configuration.

Green Synthesis of Copper and Sulfur Nanoparticles and Their Effect on Erwinia amylovora
type: item
description: Fire blight, caused by the bacterium Erwinia amylovora, remains a persistent threat to apple and pear orchards worldwide, often leading to devastating crop losses. Conventional management strategies rely heavily on copper-based bactericides, which, despite their effectiveness, pose environmental risks and contribute to the emergence of resistant bacterial strains. In response to these challenges, this study explores the antibacterial potential of copper and sulfur nanoparticles synthesized via green methods using citrus and pomegranate peel extracts. These plant-derived nanoparticles were characterized for size and morphology and evaluated in vitro for their antimicrobial activity against Erwinia amylovora, with comparisons made to Bordeofix, a commercial copper-based pesticide. Results revealed that copper and sulfur nanoparticles achieved bacterial growth reductions of up to 90% and 85%, respectively, within 48 hours. Statistical analysis confirmed the significance of these findings, highlighting the enhanced efficacy of nanoparticle treatments compared to conventional Bordeofix approaches. This work underscores the promise of green-synthesized nanoparticles as sustainable tools in plant disease management. By leveraging agricultural waste materials and minimizing chemical inputs, the approach aligns with broader goals of ecological stewardship and integrated pest management. The findings pave the way for future field applications and policy shifts toward environmentally responsible solutions in horticultural disease control.

Silver Oxide and Silver Iodide Nanomaterials Through the Green Synthesis from Acacia Senegal Plant and Biocompatibility Their Use as Anti-liver Cancer Agents
type: item
description: Silver iodide (AgI) can be obtained from Acacia Senegal and has the potential to inhibit cancer growth. The present investigation using relevant techniques, can be used for the liver cancer (HePG2) in the cell line treatment with silver oxide (AgO) nano-crystallites. This was achieved by exposing Liver cancer cell (HePG2) and healthy cells (WRL68) to 25,50,100,200, and 400 μg/mL concentrations of AgO. The novelty of the present study is comparison of the two types of cells: the (HePG2) and (WRL68) to the (AgI) from A. Senegal plant, which to our knowledge has not been reported. We also used the IC50 assay, which is a measurement used to describe the effectiveness of a substance in inhibiting or suppressing a specific enzyme or cell activity. The IC50 value represents the concentration of the substance required to inhibit the target biological activity by 50%.the graph in Figure shows an IC50 value of 70 in liver cancer cells, which is a positive result. However, the IC50 value in healthy cells was somewhat low at 193.These are good results because the lower the IC50 value in cancer cells, the better the outcome, and the opposite should be true for healthy cells.

Alkali and Alkaline Earth Metal-centered B12N12 Nanocages: A Theoretical Study on the Possibility of Their Application for the Removal of Mefenamic Acid from Aqueous Media
type: item
description: Pharmaceutical pollutants in water resources are considered as a significant threat to environmental safety and human health. This work addresses this challenge by studying the adsorption of mefenamic acid (MFA) onto the pristine, and alkali and alkaline earth metal ions-centered B12N12 nanocage. The most favorable adsorption of MFA on the B12N12 nanocage takes place between the boron atom and the oxygen atom of the carboxyl group in MFA. For the nanocage centered with alkali and alkaline earth metal ions, the best results were obtained when the Be²⁺ and K+ ions are located at the center of the nanocage, in charged and neutralized forms, respectively. Among all nanocages studied in this work, K+@B12N12Cl⁻nanocage showed best performance in the aqueous media. The IGMH and NCI analyses confirmed strong interactions between the adsorbent and MFA in all cases. Moreover, ELF analysis revealed that a single bond forms between the drug and the nanocage, supporting the chemical nature of the adsorption. In fact, while pristine boron nitride nanocages (B12N12) can be potentially applied for drug delivery, their adsorption capacity is moderate. This study demonstrates a unique success: the encapsulation of B12N12 with Be²⁺ and specially K⁺ ions significantly enhances its adsorption capacity.

RSM-CCD Optimized EDTA-functionalized Magnetic Activated Carbon Derived from Sunflower Stem for Adsorptive Removal of Ni2+ and Malachite Green from Containment Water
type: item
description: The structure of malachite green (MG) molecules makes them highly resistant to environmental degradation, posing significant challenges for removal. Similarly, heavy metals such as Ni2+ present substantial risks due to their toxicity and persistence. The presence of MG and Ni2+ in water and wastewater is frequently reported at levels exceeding standard limits, highlighting the urgent need for effective removal and degradation strategies. Herein, EDTA-functionalized magnetic activated carbon (EDTA-FMAC) derived from sunflower stems was developed and successfully applied for the removal of MG and Ni2+ from contaminated water. The adsorbent (MAC) was characterized using FTIR, XRD, SEM, Raman, VSM, and BET techniques. Key factors, including sorbent weight, contact time, initial pollutant concentration, and pH, were optimized using Response Surface Methodology (RSM). The study achieved maximum adsorption efficiencies of 97.68% for MG and 94.63% for Ni2+ at initial concentrations of 15 and 20 mg/L, adsorbent weights of 9 and 20 g, contact times of 25 and 20 minutes, and pH levels of 6 and 4, respectively. The experimental data aligned closely with the Freundlich isotherm model and the pseudo-second-order kinetic model. Thermodynamic analysis indicated that MG and Ni2+ adsorption onto magnetic activated carbon is endothermic and spontaneous. This study demonstrates that EDTA-functionalized magnetic activated carbon derived from sunflower stems is an efficient, effective, and reusable adsorbent for the removal of MG and Ni2+ from tap water.

Time-Controlled Photoassisted Deposition of Silver on Tio2 Nanotube Arrays: Tuning Plasmonic for Enhanced Photoelectrochemical Performance
type: item
description: This study demonstrates that time-controlled photoassisted deposition of silver (Ag) nanoparticles can effectively tune the plasmonic and photoelectrochemical behavior of TiO2 nanotube arrays (TNTs/Ti foil). Structural analyses confirmed the preservation of phase-pure anatase TiO2 and revealed progressive Ag loading with deposition time. FESEM observations showed that early deposition (5–15 min) primarily thickened tube walls, increasing the outer diameter from ~210 to ~250 nm, while distinct Ag nanoparticles were not yet resolved. At longer deposition times (20–25 min), well-defined Ag particles appeared, growing from ~450 to ~750 nm, indicating coalescence and aggregation. These morphological changes corresponded with optical responses, where a pronounced LSPR band emerged at ~620 nm and the apparent band gap decreased from 3.20 eV for pristine TNTs to 2.7 eV at 10 min Ag coverage. Photoelectrochemical measurements highlighted the importance of deposition time: photocurrent density increased from 0.11 mA cm-2 for pristine TNTs to a maximum of 0.39 mA cm⁻² at 10 min, over 3.5-fold enhancement, before declining due to aggregation-induced recombination. Overall, these results show that precise control of Ag deposition time governs nanoparticle nucleation, growth, plasmonic behavior, and interfacial charge transfer, providing a scalable strategy for designing high-performance plasmonic photoelectrodes.

Antibacterial Activity of Nisin Incorporated into Chitosan/Alginate Nanoparticles as a Biopreservator Agent in Sausage
type: item
description: This study investigates the antimicrobial effects of nisin extracted from Lactococcus lactis and the enhancement of its antimicrobial effect by incorporation into chitosan/alginate nanoparticles. Native strains of Lactococcus lactis were isolated from milk samples and the presence of the nisin gene was confirmed using polymerase chain reaction (PCR). Nisin concentration was determined using high-performance liquid chromatography (HPLC). The results showed that out of ten isolated strains, four strains (L1, L3, L8 and L9) showed genetic similarity to Lactococcus lactis with percentages of 82.45%, 79.87%, 93.33% and 79.87%, respectively. The optimal growth conditions for the most effective strain were determined at 30°C and pH 7 with an optical density of 5.51 at 600 nm. Nisin extract showed a significant inhibitory zone of 19 mm against Bacillus cereus, while nisin-containing nanoparticles showed an enhanced inhibitory effect of 20 mm. Furthermore, the results showed that the combination of nisin-containing nanoparticles significantly improved the antimicrobial activity compared to nisin alone. This study showed that nisin incorporated into nanoparticles effectively retained its antimicrobial properties, indicating its potential as a valuable model for biopreservation of food. These findings emphasize the importance of using natural antimicrobials in food preservation.

Band Gap Enhancement and Violet Luminescence from Chemically Synthesized Copper Oxide Nanospindles and Its Antimicrobial Activity Against S. Aureus and K. Pneumoniae
type: item
description: A simple wet-chemical method has been deployed to synthesize copper oxide (CuO) nanostructures. FESEM images revealed the formation of uniform-sized, spindle-like nanostructures. The TEM image revealed that the nanospindles are composed of several small crystallites. The distinct diffraction peaks in the XRD pattern confirm well-crystalline nanostructures and the average crystallite size was ~10 nm. FTIR spectra revealed the formation of Cu-O bonds. The band gap of the nanocrystals was calculated from the absorption spectra and was estimated to be 3.28 eV. Quantum confinement effect is therefore found to be very significant in these nanocrystals, manifested by the band gap enhancement. The synthesized CuO nanospindles exhibit strong photoluminescence peaked at ~ 407 nm owing to band-to-band transition. This emission peak is due to the transition associated with low energy peaks at ~ 461 nm due to shallow levels created below the bottom of the conduction band. The nanostructure showed significant antimicrobial activity against S. Aureus (Gram-positive) and K. Pneumoniae (Gram-negative) bacteria as studied by agar well diffusion technique. The zone of inhibition depends on the concentration of nanoparticles as revealed from the study. Therefore, the synthesized CuO is of immense potential for optoelectronics and biomedical applications.

The Effect of Chitosan Nanoparticles Loaded with Ganoderma Lucidum Polysaccharide Content on the Expression of Bax and Bcl-2 Genes and Induction of Apoptosis in the PC3 Cell Line
type: item
description: Research into anti-cancer compounds from natural sources, such as Ganoderma lucidum and chitosan, and the development of their delivery systems, is a highly promising field. This study focused on developing nanocarriers of Ganoderma lucidum polysaccharides-chitosan and evaluating their effects on the expression of the Bax and Bcl-2 genes in the PC3 cell line. The extraction of polysaccharides from Ganoderma lucidum involved heating the material in water at 70 °C, followed by treatment with 96% ethanol and subsequent protein removal to purify the polysaccharides. These polysaccharides were successfully incorporated into chitosan nanoparticles via ion-exchange copolymerization. Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) were utilized to examine the morphology and chemical properties of the synthesized nanoparticles. The effects of the chitosan-polysaccharide nanoparticles and free polysaccharides on gene expression were assessed using real-time PCR after treating PC3 cells with various concentrations. The results showed that the nanoparticles and polysaccharides increased Bax gene expression by 4.6-fold and 5.56-fold, respectively, while decreasing Bcl-2 expression by 0.64-fold and 0.81-fold, respectively. These observed changes indicate that apoptosis was induced in PC3 cells. Nanoparticles composed of polysaccharides and chitosan show promise for future prostate cancer therapies; however, additional in vitro and in vivo studies are necessary.

Synthesis of Potassium-Silica Nanofluid Fertilizer from Banana Peel and Rice Husk Waste for the Growth of Sweet Corn Plants
type: item
description: The increasing market demand for sweet corn has made it a widely cultivated crop among local farmers. One method of enhancing sweet corn productivity is combining potassium sulfate nanofertilizers from banana peel waste and nanosilica from rice husk waste. Nanosilica was synthesized using the sol–gel method; nanopotassium sulfate was synthesized by precipitating potassium using ammonium sulfate. Characterization results from FTIR (Fourier Transform Infrared Spectroscopy), XRD (X-Ray Diffraction), FESEM-EDX (Field Emission Scanning Electron Microscopy with Energy Dispersive X-ray), and TEM (Transmission Electron Microscopy) showed that the potassium–silica nanofluid fertilizer had a particle size of 8.6 nm. A single application of nanosilica enhanced the vegetative growth of sweet corn. Applying nanopotassium sulfate significantly increased plant height, especially in the S3W1 treatment 28 DAS (days after sowing). The combination of application time and concentration of potassium–silica nanofluid fertilizer had a significant effect on plant height. Best results were obtained with a concentration of 5 mL applied 35 DAS.

type: item
description: This work examined the oriented external electric field (OEEF) along x, y, and z-axes in the interaction between vanadocene dichloride (VDC) anticancer drug and C@Al12 cluster. OEEF effect on the electronic energy and interaction energy values was studied. These results indicated weaker adsorption in VDC…C@Al12 complex in the presence of OEEF along the z-axis than x, and y-axes. Variations of polarity and frontier orbital energy values of the molecule with strength of OEEF were reported. Greater polarity was found with higher OEEF strength. The most contribution in the SOMO and LUMO of the VDC…C@Al12 complex were belonged to C@Al12 and VDC moieties, respectively. Also, dependencies of reactivity parameters on OEEF strength were provided. Cl×××Al interactions were illustrated with electron localization function (ELF) and charge displacement curves (CDC) results.

Influence of Tannic Acid pH on the Crystallographic Structure and Electrical Properties of ZnO Nanostructured Thin Films
type: item
description: This study presents a comprehensive investigation into the structural, chemical, and electronic properties of zinc oxide (ZnO) and tannic acid-functionalized ZnO (ZnO–TA) nanostructures, synthesized via a green hydrothermal route under controlled pH conditions. FESEM revealed that pristine ZnO crystallized into well-defined nanorods, whereas incorporation of TA at acidic pH values induced a morphological transition towards interconnected networks, concomitant with elevated carbon incorporation. FTIR confirmed the presence of Zn–O vibrational modes alongside characteristic peaks corresponding to carbonyl, ester, and hydroxyl functionalities, evidencing successful surface modification by TA. The four-point probe I–V measurements demonstrated linear ohmic behaviour and a significant enhancement in lateral conductivity, reaching up to 10⁻⁸ S·cm⁻¹, surpassing previously reported benchmarks for similar systems. Hall effect measurements consistently indicated n-type conductivity across all samples. Notably, carrier mobility peaked at pH 5, attributed to effective passivation of surface trap states by TA’s functional groups. In contrast, excessive TA loading at pH 3 resulted in increased carrier concentrations but diminished mobility, likely due to nanoparticle aggregation and enhanced grain boundary scattering. These findings demonstrate the pivotal influence of pH and TA concentration in tailoring the morphology, surface chemistry and charge transport characteristics of ZnO nanostructures.

Development of a Health Risk Management Framework in Workplaces Handling Nanomaterials Using Multi-Criteria Decision-Making Methods
type: item
description: This study developed a comprehensive framework for assessing and managing health risks of manufactured nanomaterials (MNM) in workplaces. The approach combined control banding with multi-criteria decision-making, informed by expert input and a literature review on MNM hazards. A three-layered risk assessment was applied: hazard banding using the Globally Harmonized System (GHS) for five toxic endpoints, exposure banding based on MNM physical state, manufacturing processes, and working conditions (yielding four bands), and integration via control banding to classify risk into five levels. These layers complement each other to enhance accuracy. Control measures were identified and evaluated using a General Technique for Evaluating Control Measures (GTECM), scoring effectiveness, cost, and feasibility, with acceptable inter-rater reliability. The framework was implemented as an online tool to support practical application in Iranian nanotechnology workplaces. Field testing in selected facilities demonstrated its usability and consistency. By systematically integrating hazard, exposure, and control data, the framework supports informed decision-making for occupational health and safety managers. It aims to strengthen risk management practices and promote safer handling of MNMs, contributing to improved workplace health in Iran’s growing nanotechnology sector.

Enhanced Photocatalytic Degradation of Pharmaceutical Industrial Effluent Using TiO2 and N-doped TiO2 Nanoparticles Under Natural Sunlight: A Comparative Study
type: item
description: Despite the rapid growth of pharmaceutical industries to meet rising demand, untreated or poorly treated wastewater continues to contaminate water bodies, posing serious risks to ecosystems and human health. Conventional treatment methods often fall short in effectively addressing these complex and persistent pollutants. In this context, nanomaterials have emerged as promising candidates for advanced water purification. This study presents a novel approach by employing TiO2 and nitrogen-doped TiO2 (N-TiO2) nanoparticles, synthesized via a simple and scalable sol-gel method, for the treatment of actual pharmaceutical industrial effluent under natural sunlight, a cost-effective and sustainable condition rarely explored in previous works. The synthesized photocatalysts were thoroughly characterized using UV, XRD, SEM, FTIR, and EDX analyses. Unlike most previous studies focused on model pollutants, this work directly addresses the degradation of real pharmaceutical wastewater by combining adsorption and photocatalysis. Higher adsorption efficiencies were observed for N-doped TiO2 nanoparticles (43.77%) compared to TiO2 (21.34%) after 2 hours. Photocatalytic treatment further enhanced the degradation to 57% (N-TiO2) and 22% (TiO2) after 3 hours under natural sunlight. The study demonstrates the potential of N-TiO2 as an efficient, sunlight-driven photocatalyst for practical wastewater treatment applications, highlighting its novelty and real-world applicability.

The Capability of Pure and Metal-Encapsulated All Boron Fullerenes (B40) as Nanocarriers for β-Lapachone Anticancer Drug Delivery: DFT Study
type: item
description: This work employs density functional theory (DFT) to explore the interactions between the anticancer agent β‑Lapachone (β‑Lap) and pristine B40 fullerenes as well as their potassium- and magnesium-encapsulated counterparts (K@B40 and Mg@B40). The results reveal significant interactions affecting the electronic structures of these molecules, with stable complexes formed and a notable reduction in energy gaps, indicating effective β-Lap adsorption. The β-Lap drug exhibits stronger binding to metal-encapsulated fullerenes than to pristine B40 in both aqueous and gas environments, with binding energies in water of approximately -5.2 kcal/mol for B40, -82.9 KCal/mol for Mg@B40, and -55.7 KCal/mol for K@B40. In aqueous media, the dipole moments of encapsulated complexes rise to nearly twice their gas-phase values. To complement the electronic structure insights, we employ Quantum Theory of Atoms in Molecules (QTAIM) to study the electron densities and their Laplacians, and Natural Bond Orbital (NBO) analysis to evaluate donor–acceptor interactions and charge redistribution within these complexes. Despite the strong adsorption energies, the interaction weakens in acidic conditions, facilitating drug release. These findings suggest that B40 and its metal-encapsulated derivatives are promising nanocarriers for β-Lap delivery, combining strong binding with controlled release potential in biological environments.

A Novel Hazelnut Shell/Magnetite Bio-Nano adsorbents for Enhanced Oil Removal From Oil-Contaminated Waters
type: item
description: The primary objective of this study is to evaluate the feasibility of using hazelnut shells as a biosorbent for the cleanup of oil and petroleum product spills in water bodies. The effects bioadsorbent, nanoparticle concentrations, oil concentration, temperature (10-4000C), and pH on oil adsorption were investigated to determine the optimal conditions for maximum purification efficiency. The highest oil removal efficiency achieved with the biosorbent was 61.25% at a pH of 7.5. To enhance the sorption capacity of the biosorbents were synthesized by incorporating Fe₃O₄ superparamagnetic nanoparticles at concentrations of 1%, 3%, 5%, and 10%. Characterization of both the biosorbents was conducted using SEM, TGA, and FTIR analyses to assess the interaction between Fe₃O₄ nanoparticles and the plant-derived surface of the biosorbent. For an adsorbent such as hazelnut shell+Fe₃O₄ bio-nanoadsorbent, the pHzpc indicates the point at which the surface of the bio-nanoadsorbent changes from negatively charged to positively charged as the pH of the solution increases or decreases. The zero-charge pH point of the bio-nanoasorbent was determined to be pH=8 by Boehm titration. The optimal adsorption conditions for the bio-nanosorbent, composed of hazelnut shell and 10% Fe₃O₄ nanoparticles, were found to be 92.5% oil removal within 12 minutes at a pH of 7.5.

Leveraging the Therapeutic Role of Nanotechnology in Osteoporosis Management: Current Progress and Perspectives
type: item
description: Osteoporosis (OP) is a bone degenerative disease, wherein progressive deterioration of microarchitecture of bones make them porous, fragile and brittle leading to bone hollowing. OP is characterized by decrease in bone mineral density (BMD) wherein spine, shoulder, hip, wrist bones are more prone to fracture risks that causes high morbidity and socio-economic burden. This necessitates early diagnosis of OP and prediction of fragility fracture risk. Conventional diagnostic methods, include Dual-Energy X-ray Absorptiometry (DXA), do not give accurate predictions of risk of fractures as minor changes in bone structure are often overlooked. The fact that most fractures occur at non-osteoporotic BMD values, despite the operative diagnosis being based on BMD, is an obstacle in management of OP. With the advent of artificial intelligence, a series of reports suggest deep learning applications in screening and diagnosis of OP. Deep learning methods can emerge as a promising method for detection and diagnosis of osteoporotic fractures via machine learning (ML). The ever-expanding field of nanotechnology has witnessed rapid development of its potential application for OP treatment. While traditional therapies for OP are effective, their use are severely limited due to reduced bioavailability, non-specific distribution coupled with adverse effects. Nanotherapeutics have emerged as a promising approach for managing OP. The unique physicochemical properties of nanoparticles include tunable surface characteristics, ultra-small size, high surface-to-volume ratio that empower them to overcome the confines of traditional therapies. Nanotechnology applications in OP therapeutics are still in the early phases, with more research needed to fully uncover its potential.

DFT Study of HCl The Clusters Under Nano Confinement of Carbon Fullerenes
type: item
description: This report reveals the geometry, vibrational properties, and molecular orbitals with HOMO-LUMO energies of HCl clusters (HCl)n=1-2 under the confinement of carbon fullerenes CN=42-52 at B3LYP level with basis set 6-311++g(d,p). Due to the effect of the H-bond network, the variation in bond length is observed relative to the variation of diameter of carbon fullerenes from C42 to C52. Unexpectedly, the high intermolecular stretching mode (3403.96 cm-1) is observed for a shorter bond length (H-Cl =1.234 A0) under C46. The confined HCl under C52 results in high intensity (57.75 units) for stretching mode 2859.36 cm-1 with high polarity prediction but on the other hand confined HCl dimer under C44 shows the highest stretching mode in the frequency range 3000 cm-1 with compressed bond length (H-Cl=1.254 A0) which acts as an unsaturated system. For HCl, under the confinement of C52, the bond length increases up to 1.292 A0 which is quite greater than the experimental value of free HCl (1.275 A0). Exclusively the band gap energies of both the clusters (HCl)n=1-2 are also considered to study H-bond connectivity with carbon atoms by using their (HOMO-LUMO).

Endophytic Nanoparticles: Promising Growth Promoter, Modulate Biochemical Constitutes in Vigna radiata Seedlings, and Antifungal Activity
type: item
description: Over the years, nanotechnology has been utilized in the agricultural sector for sustainable production. The application of endophytes-mediated silver nanoparticles is gaining momentum in various sectors including agriculture. This current study aims to evaluate the impact of endophytic bacteria-mediated silver nanoparticles in promoting plant growth and improving biochemical constituents in Vigna radiata by using the nanopriming method. Bacillus cereus isolated from the flower of Nyctanthes arbor-tristis was identified and utilized for silver nanoparticles synthesis, this is called Bacillus cereus silver nanoparticles (BC-AgNPs). Synthesis of silver nanoparticles was confirmed by colour change and characterization by UV-Vis spectrophotometer, FESEM, FTIR, DLS, and EDAX. Seeds of Vigna radiata were treated with different concentrations (1ppm, 2.5ppm, 5ppm and 10ppm) of BC-AgNPs. Plant growth was enhanced at a concentration of 5 ppm of BC-AgNPs. In addition, an increase in photosynthetic pigments, protein, and carbohydrate was observed in the nanoprimed seedlings when compared to that of the control. Also, the ability of the synthesized particles to inhibit the growth of phytopathogenic fungi Penicillium janthinellum was examined. The results suggest that silver nanoparticles synthesized via endophytic bacteria can be utilized as dual-function agent in sustainable agriculture – both as a plant growth enhancer and as a biocontrol agent.
