- Plasma Physics: Dusty plasma physics is a specialized branch of plasma physics that focuses on plasmas containing electron, ions and charged less dust particles suspended in the ionized gas. These dust particles interact with the surrounding plasma through electrostatic forces, leading to unique behaviors and phenomena. Dusty plasmas are found in many natural environments, such as in space and in cometary tails, and are also found in laboratory. The study of dusty plasmas provides insights into fundamental plasma dynamics, as well as practical applications in materials science, space exploration, and industrial processes involving plasma-based technologies.
- Cloud Electrification: Cloud electrification refers to the process by which clouds accumulate electrical charges, leading to the development of lightning and thunder. This phenomenon occurs primarily in convective clouds, such as thunderclouds, where the movement of supercooled water droplets, ice crystals, and snow particles causes collisions that transfer electrical charge. As a result, different regions of the cloud acquire positive or negative charges, creating an electric field strong enough to trigger lightning discharges, either within the cloud, between clouds, or to the ground. Understanding cloud electrification is essential for predicting and mitigating the effects of thunderstorms and lightning-related hazards.
