Forensic toxicology plays a pivotal role in investigations. It involves the analysis of physical samples to detect and determine the presence of substances. This knowledge is vital in unraveling complex situations, providing invaluable evidence that can shed light on accidents. Chemists meticulously examine samples such as blood to identify the p

Semiconductors play a fundamental role in modern electronics due to their ability to regulate the flow of electricity under specific conditions. They can be broadly classified into two categories: intrinsic and extrinsic semiconductors. Intrinsic semiconductors, such as pure silicon or germanium, possess limited conductivity because their valence b
