Ultra-thin layers of rust generate electricity from flowing water
There are many ways to generate electricity—batteries, solar panels, wind turbines, and hydroelectric dams, to name a few examples… and now, there's rust.

(PhysOrg.com) -- A new ultracapacitor or electric double-layer capacitor (DLC) design has been announced in the journal Science this week, and could pave the way for smaller and lighter portable electronics devices.
(Phys.org)—For the first time, scientists have integrated transparency into freestanding, flexible graphene paper (FFT-GP), and demonstrated that the new material can greatly improve the performance of supercapacitors.
Ultra-low-loss metal films with high-quality single crystals are in demand as the perfect surface for nanophotonics and quantum information processing applications. Silver is by far the most preferred material due to low-loss ...
(PhysOrg.com) -- Ever since it's relatively recent discovery, graphene has generated a great deal of interest. Graphene is extracted from graphite in many cases, and consists of a sheet of carbon atoms bound together in a ...
