An aluminum graphite battery that could charge your smartphone in 60 seconds
Smartphones are pretty amazing devices, but their most vexing problem remains battery life. No matter how power efficient the hardware gets, manufacturers end up using all of it and more for improved displays, faster performance, and more features. Now scientists at Stanford University may have come up with what is nothing short of the Holy Grail for mobile devices: an ultra-fast-charging aluminum battery that could be produced on a mass scale.
New graphene nanofiltration application may enable faster, more durable water filters
(Nanowerk News) For faster, longer-lasting water filters, some scientists are looking to graphene --thin, strong sheets of carbon -- to serve as ultrathin membranes, filtering out contaminants to quickly purify high volumes of water.
