source: Indian Institute of ScienceThe human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can't see, has an even lower frequency than red light. Researchers at the Indian Institute of Science (IISc) have now fabricated a device to increase or "up-convert" the frequency of short infrared light to the visible range.Up-conversion of light has diverse applications, especially in defense and optical communications. In a first, the IISc team used a 2D material to design what they call a ...

source:Tokyo Institute of TechnologyResearchers from Tokyo Tech have identified hexagonal perovskite-related Ba5R2Al2SnO13 oxides (R = rare earth metal) as materials with exceptionally high proton conductivity and thermal stability.Their unique crystal structure and large number of oxygen vacancies enable full hydration and high proton diffusion, making these materials ideal candidates as electrolytes for next-generation protonic ceramic fuel cells that can operate at intermediate temperatures without degradation. The study presents a significant advancement in fuel cell technology.Fuel cells ...
