Heavy metal impurities are typically discovered in cosmetic products since they are abundant naturally. Lipstick's metal concentration has raised health concerns across the globe. This is so because applying cosmetics to the face always starts with lipstick. Since they are a potential source of daily, widespread, and frequently long-term exposure to a range of chemicals, the safety of cosmetic and personal care products has co Read More

Contamination from heavy metal ions is a rising problem. It has direct and indirect impacts on human health, the environment, and aquatic life. Thus, detecting trace amounts of these elements presents significant challenges. It is important to develop effective, affordable, accurate, fast sensing monitoring systems. A new field of sensing techniques has emerged with the discovery of bio-compatible fluorescent carbon na Read More

BackgroundThe study systematically investigates the influence of annealing temperatures, ranging from 500°C to 900°C with 100°C increments, on the microstructural characteristics of cobalt ferrite (CoFe2O4) nanoparticles.MethodsThe nanoparticles, with sizes between 7-18 nm, were synthesized using the co-precipitation method. X-ray diffraction (XRD) analysis reveals that higher annealing temperatures correspond t Read More

ObjectiveThe main goal of the current research was to investigate the influence of a wall-bounded medium on the settling behaviour of flexible planktonic particles. The particles are permeable and immersed in a Newtonian, incompressible, and viscous fluid.MethodsThis study employed the Immersed Boundary Method to analyze the interaction between the fluid and the flexible planktonic particles.ResultsThe research findin Read More
