Bio-inspired Nanocomposite Membranes for Osmotic Energy Harvesting: Joule

Posted on by Robin Edgar

Context & Scale Osmotic energy is a renewable energy with zero emissions and minimal daily variations. However, the membranes for osmotic energy harvesting must have multiple properties that are thought to be impossible to realize to make this technology viable. Here, we show that cartilage-inspired cation-selective composite membrane assembled from aramid nanofibers and boron nitride Read more about Bio-inspired Nanocomposite Membranes for Osmotic Energy Harvesting: Joule[…]

Double-slit experiment done using time instead of space

Posted on by Robin Edgar

The experiment relies on materials that can change their optical properties in fractions of a second, which could be used in new technologies or to explore fundamental questions in physics. The original double-slit experiment, performed in 1801 by Thomas Young at the Royal Institution, showed that light acts as a wave. Further experiments, however, showed Read more about Double-slit experiment done using time instead of space[…]

ICE Is Grabbing Data From Schools, Abortion Clinics and news orgs with no judicial oversight

Posted on by Robin Edgar

US Immigration and Customs Enforcement agents are using an obscure legal tool to demand data from elementary schools, news organizations, and abortion clinics in ways that, some experts say, may be illegal. While these administrative subpoenas, known as 1509 custom summonses, are meant to be used only in criminal investigations about illegal imports or unpaid Read more about ICE Is Grabbing Data From Schools, Abortion Clinics and news orgs with no judicial oversight[…]
