Sep 08, 2022 (Nanowerk News) Green hydrogen from renewable electricity and derived e-fuels are uniquely valuable for achieving climate neutrality. They can replace fossil fuels in industry or long-distance transport where direct electrification is infeasible. However, even if production capacities grow as fast as wind and solar power, the growth-rate...
New on-chip frequency comb is 100x more efficient
Sep 08, 2022 (Nanowerk News) On-chip laser frequency combs — lasers that emit multiple frequencies or colors of light simultaneously separated like the tooth on a comb — are a promising technology for a range of applications including environmental monitoring, optical computing, astronomy, and metrology. However, on-chip frequency combs are...
Light accelerates conductivity in nature’s ‘electric grid’
Sep 07, 2022 (Nanowerk News) The natural world possesses its own intrinsic electrical grid composed of a global web of tiny bacteria-generated nanowires in the soil and oceans that “breathe” by exhaling excess electrons. In a new study, Yale University researchers discovered that light is a surprising ally in fostering...
A cosmic tarantula, caught by the Webb telescope
Sep 07, 2022 (Nanowerk News) Once upon a space-time, a cosmic creation story unfolded: Thousands of never-before-seen young stars spotted in a stellar nursery called 30 Doradus, captured by NASA’s James Webb Space Telescope. Nicknamed the Tarantula Nebula for the appearance of its dusty filaments in previous telescope images, the...
Advanced microscope techniques could pave way for improved computer memories
Sep 07, 2022 (Nanowerk News) Anyone who has watched steam billow up from a boiling kettle or seen ice crystals form on a wet window in winter has observed what scientists call a phase transition. Phase transitions — such as those between solids, liquids and gases — occur in all...
