Semiconductors are materials with electrical conductivity between that of a conductor and an insulator, crucial for modern electronics. They are the foundation of integrated circuits and devices like transistors, enabling the miniaturization and performance enhancement of electronic technologies.

semiconductors

Sensors are devices that detect and respond to physical stimuli by converting them into measurable signals, often used for monitoring, control, and automation in various applications. They play a crucial role in the Internet of Things (IoT), enabling real-time data collection and analysis for smarter decision-making across industries.

sensors

Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process, allowing them to be used repeatedly. They work by providing an alternative reaction pathway with a lower activation energy, which enhances the efficiency and speed of reactions in various industrial and biological processes.
