CdTe-based quantum dots (QDs) have been used as active materials in various applications, such as sensing, imaging, and light-harvesting devices where the QDs are continuously illuminated by suitable lights. Passivation of CdTe QDs with stable inorganic layers to form core/shell or core/multiple-shell structures has been demonstrated to improve the stabilities of QDs against illumination.

This study utilizes Geo-Slope 2D to evaluate slope stability along Route 14G, integrating soil characteristics and historical rainfall data to analyze the slope stability based on the Factor of Safety (FoS). Key findings highlight the significant role of Soil-Water Characteristic Curves (SWCCs) and permeability coefficients in determining slope responses to varying rainfall levels.

The article focuses on developing an adaptive electronic stability controller for electric cars modelled on software MatlabSimulink. Design a vehicle stability controller within the scope of surveying the slippage of four tyres in the stability limit ellipse corresponding to the driving angle when using a fuzzy adaptive electronic stability controller (Fuzzy-ESC) compared to compared with the electronic stability control swarm optimization controller (PSO-ESP), it minimizes skids and vehicle rollovers during obstacle avoidance, lane changing, corner entry/exit and sudden acceleration.
