In-situ polymerization method was adapted to prepare a novel tin cerium phosphate-polyaniline nano composite ion exchange material. The physico-chemical properties of the material were determined using Fourier Transform Infra-Red (FTIR) Spectroscopy, Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), and X-ray diffraction (XRD). X-ray diffraction study showed that the composite material formed is highly crystalline in […]
Iron oxide nanoparticles are smart materials that have been commonly used in medicine for diagnostic imaging, drug delivery, and therapeutic applications. In this study, Iron oxide nanoparticles and Doxorubicin (DOX)- Chrysin (Chr), were absorbed into triblock copolymer (PCL-PEG-PCL) for narrow behavior. PCL-PEG triblock copolymers were synthesized by ring-opening polymerization of ε-caprolactone (ε-CL) with polyethylene glycol […]
With the emerging newer energy storage applications, transition metal vanadates are booming up as a better catalyst. Among all the transition metal vanadates, nickel vanadate nanoparticles (Ni3V2O8 NPs), are considered as a promising material with electrocatalytic and photocatalytic activity. We herein report circular and ovular structured Ni3V2O8 NPs by hydrothermal route without using any capping […]
In this article, the growth kinetic and optical property of amorphous carbon (a-C) nanolayers deposited by ion beam sputtering deposition technique on glass substrates are investigated. The atomic force microscopy is used to measure the variation of surface roughness versus deposition time. According to the calculations, the roughness of thin films increases during the growth […]
III-Nitride NanoWire array Solar Cells (NWSCs) combine the inherent properties of III-N semiconductors with waveguiding and confinement properties of nanowire arrays. In the present paper, some design guidelines of NWSCs made from Indium-Gallium-Nitride InGaN alloys are presented. Firstly, a detailed balance analysis was performed to show the importance of using InGaN materials to effectively convert […]
The devices with additional gates like Fin Field effect transistor (FinFET) provide higher control on subthreshold parameters and are favorable for Ultra large-scale integration. Also, these structures provide high control on current through the channel and with minimum leakage. In this paper we designed a FinFET with high-K gate dielectric material i.e Hafnium oxide as […]
In this study, a new nanoscale U-shaped tunnel field-effect transistor (US TFET) structure is proposed. In order to start the design process, the drain region of the conventional US TFET is divided into two distinct parts with N+ and N– doping which is named the drain doping engineering (DDE). It is considered that the tunneling […]
Natural Circulation Loop (NCL) which is also called as a thermosyphon system is the heat transfer loop which uses no pump or external device to drive the loop fluid. In the present paper, a comparative study on thermal characteristics of two loop fluids viz. water and Al2O3/water nanofluid is made. Experiments are conducted on in-house […]
The thermophysical properties and thermal performance of water- and ethylene-glycol-based nanofluids containing and CuO nanoparticles were examined. Nanofluids were prepared at four concentrations (1- 4 vol%) using an electric mixer and magnetic stirrer, and the thermophysical properties were measured. Surfactants were used to improve stability. The transient hot-wire method (KD2-Pro device), Dynamic Light Scattering (DLS), […]
Natural bioactive compounds, such as essential oils, with antimicrobial or antioxidant activity, have received considerable attention recently, especially with rising concerns on the safety of synthetic food preservatives. However, due to their low water solubility and structural stability, their incorporation into water-based food formulations are limited, as is the other lipophilic functional compounds. Moreover, in […]
