Strain-Induced Modulation of the Electronic and Optical Properties of Janus MoSSe Monolayer: A First-principles Study

Kevin C. Ndeche & Azubike J. Ekpunobi · Journal of Materials Science Research and Reviews · 2026

This study investigates the strain-dependent electronic and optical properties of a Janus MoSSe monolayer using first-principles density functional theory calculations incorporating spin-orbit coupling (SOC). In the unstrained structure, the monolayer is a direct-band-gap semicon...

Implementation of Coulomb Counting Method for Estimating the State of Charge of Lithium-Ion Battery

Kevin C. Ndeche & Stella O. Ezeonu · Physical Science International Journal · 2021

An accurate estimate of the state of charge, which describes the remaining percentage of a battery’s capacity, has been an important and ever existing problem since the invention of the electrochemical cell. State of charge estimation is one of the important function of a battery...
