(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 ...
Chemists from the University of Würzburg have combined different dye molecules in aggregates and thereby observed surprising properties. Their discovery may help to use sunlight more efficiently for the generation of energy.
