Trees Used to Create Recyclable, Efficient Solar Cell
March 26, 2013 — Researchers have developed efficient solar cells using natural substrates derived from plants such as trees. Just as importantly, by fabricating them on cellulose nanocrystal (CNC) substrates, the ... > full story -
Clean Electricity from Bacteria? Researchers Make Breakthrough in Race to Create 'Bio-Batteries'
March 25, 2013 — Scientists have made an important breakthrough in the quest to generate clean electricity from bacteria. New findings show that proteins on the surface of bacteria can produce an electric current by ... > full story -
Super Batteries? Hybrid Ribbons a Gift for Powerful Batteries
March 25, 2013 — Ribbons of vanadium oxide and graphene become ultrafast charging and discharging electrodes for lithium-ion batteries in new research. The ribbons are thousands of times thinner than a sheet of ... > full story -
Glass-Blowers at a Nano Scale
March 25, 2013 — Very much like a glass-blower, researchers have managed to shape the exit hole of a glass capillary and finely control its diameter between 200 nanometers and ... > full story -
Speed of Light May Not Be Fixed, Scientists Suggest; Ephemeral Vacuum Particles Induce Speed-of-Light Fluctuations
March 25, 2013 — Two new articles challenge established wisdom about the nature of vacuum. In one article scientists have identified a quantum level mechanism for interpreting vacuum as being filled with pairs of ... > full story -
Using Fluctuating Wind Power
March 25, 2013 — Incorporating wind power into existing power grids is challenging because fluctuating wind speed and direction means turbines generate power inconsistently. Coupled with customers' varying power ... > full story -
Measuring the Magnetism of Antimatter: Antiprotons Measured More Accurately Than Ever Before
March 25, 2013 — In a breakthrough that could one day yield important clues about the nature of matter itself, scientists have succeeded in measuring the magnetic charge of single particles of matter and antimatter ... > full story
