Simulation and modeling of magnetically-assisted impaction coating (MAIC) process for dry particle coating
… of proposed research is to model, and understand the processes happening at multiple length and time scales in magnetically assisted impaction coating process. The smallest length scale is of the order of the molecular size and is important because during collisions the molecules …

Interactions of cadmium selenide (CdSe) quantum dots with coagulant proteins extracted from Moringa oleifera seeds
In order to investigate the interaction mechanism between Cadmium selenide (CdSe) quantum dots (QDs) and Moringa oleifera seeds coagulant protein (MOCP), CdSe QDs with hexagonal phase and crystalline size of 3.1-8.1 nm were synthesized in presence of organic solvent Trioctyl-n-phosphine oxide …

Phase-Engineered Field-Effect Transistors Based on Two-Dimensional Transition Metal Dichalcogenides
… based field-effect transistors (FETs) are considered promising candidates for post-Si electronics owing to their ultra-thin body enabling ultimate scalability. However, the large contact resistance at the metal/TMDC interface limits their drive current for high-performance applications. The …
