A proposed recovery technique for oil extraction not only outperforms existing drilling and recovery techniques, but also has the potential to sequester more carbon dioxide in the process.
The first lithium-ion battery has been developed that shuts down before overheating, then restarts immediately when the temperature cools. The new technology could prevent the kind of fires that have prompted recalls and bans on a wide range of battery-powered devices, from computers to hoverboards.
adminMany coastal areas and harbors go almost unprotected against acts of terror. Soon a new sensor system relying on signal echoes from cell towers can quickly detect even the smallest of attack boats. This mobile radio passive radar can also help airplanes avoid colliding with wind turbines.
Silicon wafers are the heart of solar cells. However, manufacturing them is not cheap. Over 50 percent of the pure silicon used is machined into dust. A new manufacturing technique puts an end to these material losses, with raw material savings of 50 percent along with an 80 percent reduction in energy costs.
A team of researchers has developed an elegant process for coating fragile perovskite layers with graphene for the first time. Subsequent measurements show that the graphene layer is an ideal front contact in several respects.
adminResearchers have taken atomic-level images of individual nanoparticles during heating that could lead to improved fuel-cell technologies.
adminBulletproof vests and other super-strong materials could soon become even tougher and more environmentally friendly at the same time with the help of extra firm, or ‘al dente,’ fibers. Researchers report an innovative way to spin high-performance polyethylene fibers from natural fats, such as oils from olives and peanuts.
