Scientists poring over data from NASA's Orbiting Carbon Observatory-2 mission are seeing patterns emerge as they seek answers to questions about atmospheric carbon dioxide.
Lithium-oxygen batteries have been touted as the ‘ultimate’ battery due to their theoretical energy density, which is ten times that of a lithium-ion battery. The demonstrator relies on a highly porous, ‘fluffy’ carbon electrode made from graphene.
Coffee is my go-to choice for a cognitive boost. I enjoy a morning cup of joe (almost every alternate day), but like a lot of people I’m not a fan of coffee’s bitter flavor. So to mask it, apart from adding lots of milk, I guiltily dump in a sugar cube (or maybe two). I’m not alone. Even connoisseurs of coffee, such as the Specialty Coffee Association of America, treat bitterness as a defect, describing it as “caustic,” “phenolic,” “creosol,” and “alkaline.” So, recently when my…
A group of French physicists has optimized a type of ion thruster to significantly extend its lifetime: the new development made it sturdy enough to be able withstand a long trip into deep space. Such a thruster would require 100 million times less fuel than common thrusters that use chemical reactions to propel a spacecraft forward.
