Solar Cells

Perovskite solar cells can not only emit light, they can also emit up to 70% of absorbed sunlight as lasers. Critical signaling molecules can be used to convert stem cells to neural progenitor cells, increasing the yield of healthy motor neurons and decreasing the time required to grow them. Mexican blind cavefish are so close to their sighted kin that they are considered the same species, but they use pressure waves (from opening and closing their mouths) to navigate in the dark. Electrostatic assembly allows luminescent elements (like Europium) to be embedded in nanodiamonds; these glowing…
Solar cells made with bismuth vanadate achieve a surface area of 32 square meters per gram.  This compound can be paired with cheap oxides to split water molecules (and make hydrogen) with record efficiency. Short-term geoengineering could postpone global warming, only to have it happen more quickly in the future. Carotenoids tinge blackbird bills a deep orange, signalling fitness; birds with oranger bills are "are heavier and larger, have less blood parasites and pair with females in better condition than males with yellow bills." Fibroblasts can extrude a tidy biological scaffold for stem-…
AT&T sponsored Nifty Fifty program speaker and Associate Professor of Mechanical Engineering & Materials Science at Yale University Ainissa Ramirez has created a new YouTube video series entitled Material Marvels from her lab at Yale on some pretty cool materials used in space, robots and even in your mouth! Her titles to date are Space Shuttle Tiles, Shape Memory Alloys, Solar Cells and Quasicrystals. Here is the first in her series: Ainissa Ramirez is perhaps best known for discovering a universal solder that can bond metals to ceramics, glass, diamonds and the oxide materials used…
