Plasmas are prevalent in contrasting parts of our universe, from the planetary rings of Saturn to the manufacturing processes behind the production of modern microchips. This ionized gas, comprised of positive ions and electrons, often contains nanoparticles that add extra complexity to the plasma. Our ever-shrinking microchip technology necessitates the study of dusty plasmas at the length scales of a few nanometers. These nanometer-sized dust particles become charged in plasma, consequently playing a dynamic role in dusty plasma. For his PhD research, Mohammad Hasani developed a novel diagnostic method that uses quantum dots to visualize the charging of the nanoparticles in plasma.
