Helium is a research area that focuses on the properties, behavior, and applications of the chemical element helium. Helium is a colorless and odorless gas that is the second lightest and second most abundant element in the universe. It is known for its low boiling and melting points, as well as its inertness and lack of reactivity. Research in this area includes studying helium's unique physical properties, its role in cryogenic applications, its use in cooling systems and refrigeration, and its applications in fields such as medicine, industry, and aerospace. Additionally, research is also focused on understanding helium's potential as a future energy source through nuclear fusion reactions.
