The findings are published in the journal Physical Review Letters, in a paper by graduate student Alex Frenzel, Nuh Gedik, and three others. The researchers found that by controlling the concentration of electrons in a graphene sheet, they could change the way the material responds to a short but intense light pulse. If the graphene sheet starts out with low

RESEARCHERS from Stanford have successfully used a pure lithium anode in a lithium ion battery. The common lithium-ion batteries of today tend to use an anode made of graphite or silicon, with the lithium only used in the electrolyte. While a lithium anode could boost the capacity by four fold and lower the weight of lithium ion batteries, researchers were
