A mini review on cell interactions with biological metamaterials

The mini review summarizes the interactions between biological cells and high aspect ratio nanostructures termed as biological metamaterials, while focusing on what happens at the fundamental level. The questions pertaining to the interfacial phenomenon producing modes of interaction, what instigates them, what are the favourable conditions for controlled interaction, and how are they influenced by […]

Experimental investigation on food decontamination by low-temperature dielectric barrier discharge (LT-DBD) plasma: application to bread-born mold

The microbial inactivation ability of low temperature plasma treatment generated by dielectric barrier discharge (DBD) on bread-born mold (black bread mold) is investigated. It is shown that the plasma treatment can effectively decrease the mold growth rate. The longer plasma treatment time is, the more mold spores are inactivated. On the other hand, plasma treatment […]

Evaluation of Surface Dielectric Barrier Discharge (SDBD)-Plasma Activated Normal Saline for Reduction of Escherichia coli Populations in fish (Oncorhynchus mykiss ) fillets

Recently, the antibacterial effects of plasma-activated liquids have been noticed by food industries and researchers. Some research reported that reactive oxygens and nitrogen species (RONS) that are generated in the treatment liquids destroyed cells. In this study, we evaluated surface dielectric barrier discharge (SDBD) -plasma for inactivation of Escherichia coli and quality attributes of fish […]

Improved performance of CdTe thin-film solar cell through key parameters

We investigated CdTe thin-film solar cell configuration using Silvaco Atlas. We simulated a fundamental CdTe cell at an ambient temperature of 298 K. Subsequently, we compared our simulation results to both theoretical and experimental data. The outputs demonstrated a compelling concurrence with the performance of the experimental CdTe solar cell, renowned for its record-breaking efficiency, […]

Synthesis of nanocrystalline boron ion doped SnO2 and its morphology dependent anti-microbial activity

Boron doped tin oxide nanocrystals with tetragonal symmetry (space group: P42/mnm) were prepared by sol-gel route using three different polyhydroxy alcohols like starch, glycerol and poly vinyl alcohol (PVA). Morphological and structural properties were studied for these samples by using scanning electron microscopy, X-ray powder diffraction, Raman spectroscopy and Fourier transform infrared spectroscopy. The morphology […]

Impact of Bi2O3 on the X-ray shielding characteristics of telluro-borate-bismuth glass for medical applications

The study of lead-free glasses for radiation shielding applications has drawn global attention. This work aimed to theoretically investigate the impact of Bi2O3 on X-ray shielding characteristics of telluro-borate-bismuth glass samples, in the 15 – 300 keV energy region. Sample S5 (55B2O3 – 5TeO2 – 20SrO – 5ZnO – 15Bi2O3) yielded highest LAC, MAC, and […]

Optimal Fractional-Order PID Controllers Design for Plasma Current and Horizontal Position Control in IR-T1 Tokamak Based on Particle-Swarm Optimization

Tokamak reactors’ performance is inherently tied to the precise control of plasma shape, position, and current while staying within the operational constraints, specifically managing the control signals and power supply voltages. Furthermore, many tokamak models exhibit strong coupling between control variables, necessitating the use of Multiple-Input Multiple-Output (MIMO) decoupling controllers. The primary control objectives include […]

Kelvin-Helmholtz instability in rotating dusty plasmas with sheared magnetic field and polarization force

The impact of rotation and dust polarization force on Kelvin-Helmholtz instability (KHI) in a magnetized, velocity-sheared dusty plasma is explored in this study. The investigation involves deriving the general dispersion relation from the linearized perturbation equations. The dispersion relation is solved numerically to analyze how dust polarization force and rotation influence the critical shear and […]
