Drug delivery insights were provided by performing density functional theory (DFT) calculations to investigate the adsorption of a non-steroidal anti-inflammatory drugs; ibuprofen (IBU), by an iron-doped silicon carbide (FSiC) graphene monolayer. In this regard, the single models of IBU, SiC, and FSiC were optimized to obtain their stabilized geometries and features, in which a remarkable […]
This research deals with the numerical analysis of the heat transfer characteristics of the unsteady combination of alumina-kerosene nanofluid enclosed in a porous cavity with a moving lid. The governing equations of fluid flow and conjugate heat transfer along with the relevant boundary conditions are applied to express the physical problem mathematically. First, the boundary […]
This research explores how two-dimensional honeycomb materials can be used in advanced electronics, focusing on zigzag honeycomb nanoribbons. These nanoribbons can create zero-energy band gaps, enabling helical spin current edge states. The study investigates the quantum spin Hall state, showcasing the adaptability of the Kane-Mele model in various honeycomb lattices. In addition to the theoretical […]
Damage to the central nervous system causes severe consequences for patients and increases medical costs. In spinal cord injuries, due to sensitive nerves, there is a need for a high-precision and non-invasive method to transfer macromolecules to the damaged area of the spinal cord for nerve repair. The main objective of this study is a […]
In this research, we investigate the effect of carbon nanotubes (CNTs) as a substrate on the morphology, size, magnetic behavior, and band gap energy (Eg) of nickel ferrite nanoparticles. Synthesis of NiFe2O4 nanoparticles carried out using a direct co-precipitation method in aqueous solution containing carbon nanotubes. The samples were characterized using X-ray diffraction (XRD), scanning […]
A Polyaniline/Manganese dioxide (PANI/MnO2) nanocomposite contains five weight percentages of MnO2. It has been successfully prepared by in situ polymerization. The structural, optical, and conductivity of nanocomposites remain relative to changes with respect to the weight percentage of MnO2. The structural, morphological, optical, and electrical conductivity investigation of pure MnO2, pure PANI, and nanocomposites were […]
In this paper, the electrical characteristics and sensitivity analysis of staggered type p-channel heterojunction electron-hole bilayer tunnel field effect transistor (HJ-EHBTFET) are thoroughly investigated via simulation study. The minimum lattice mismatch between InAs/GaAs0.1Sb0.9 layers besides low carrier effective mass of materials provides high probability of tunneling current that eventually boosts the device performance. Unlike the […]
In the present work, the exact diagonalization method had been implemented to calculate the ground state energy of shallow donor impurity located at finite distance along the growth axis in GaAs/AlGaAs heterostructure in the presence of a magnetic field taken to be along z direction. The impurity binding energy of the ground state had been […]
In this paper, we proposed a 2-D analytical model for electrical characteristics such as surface potential, electric field and drain current of Silicon-on-Insulator Tunnel Field Effect Transistor (SOI TFETs) with a SiO2/High-k stacked gate-oxide structure. By using superposition principle with suitable boundary conditions, the Poisson’s equation has been solved to model the channel region potential. […]
