(Phys.org)—Researchers have found that a snowflake-like fractal design, in which the same pattern repeats at smaller and smaller scales, can increase graphene's inherently low optical absorption. The results lead to graphene ...
(Phys.org)—A new study predicts that large-scale power plants based on thermoelectric effects, such as small temperature differences in ocean water, could generate electricity at a lower cost than photovoltaic power plants.
A recently discovered Weyl semimetal delivers the largest intrinsic conversion of light to electricity of any material, an international team lead by a group of Boston College researchers reports today in the journal Nature ...
