Recently, a new two-dimensional allotrope of carbon (biphenylene) was experimentally synthesized. Using first-principles calculations, we systematically investigated the structural, mechanical, electronic, and HER properties of biphenylene. A large cohesive energy, absence of imaginary phonon freque...

This paper presents a simple yet accurate method for solving the Schrödinger equation to calculate the quantum mechanical transmission probability across arbitrary potential barriers. It is based on the concept of wave impedance analogous to transmission line theory. The quantum mechanical transmiss...

Adsorption kinetic equation has been derived assuming that the process follows the behavior of a heterogeneous chemical reaction at the solid-liquid interface. This equation is converted into the Langmuir isotherm at equilibrium and describes well the unsteady-state adsorption process. Based on that...

The quest for realizing novel fundamental physical effects and practical applications in ambient conditions has led to tremendous interest in microcavity exciton polaritons working in the strong coupling regime at room temperature. In the past few decades, a wide range of novel semiconductor systems...

Transmission line techniques are used to calculate the traversal time of electrons in resonant tunneling structures. It is suggested that the real part of the quantum-mechanical wave impedance Re[(2ℏ/m*)ψ′/ψ], at resonance, can be used to calculate the electron traversal time. Furthermore, it is sho...

Abstract FeS 2 /carbon nanotube (CNT) nanocomposites were synthesized and immobilized on the surface of a glassy carbon electrode (GCE) in order to investigate the electrocatalytic conversion of 4‐aminophenol (4‐AP) into p‐quinone in an aqueous medium. The reformed electronic properties (in terms of...

The assembly of synthetic, controllable molecules is one of the goals in nanotechnology. The primary objective of this contribution is to selectively immobilize DNA on gold via electric potential control. The self-assembly monolayer (SAM) was prepared with 2-aminoethanethiol (AET) on the gold electr...

Electrochemical migration (ECM) is one of the serious failure modes encountered in electronic devices due to the electrochemical reactions triggered by the presence of moisture and bias voltage, leading to the growth of dendrites and short circuits. The classical ECM mechanism consists of four conse...
