Geometrical light trapping is a simple and promising strategy to largely improve the optical absorption and efficiency of solar cells. Nonetheless, implementation of geometrical light trapping in organic photovoltaic (OPV) is challenging due to the fact that uniform organic active layer can rarely be achieved on textured substrate. Researchers have now reported novel nanobowl optical concentrator fabricated on low-cost aluminum foil and aiming at tackling this problem.

An international team of researchers has developed a drug delivery technique that utilizes graphene strips as 'flying carpets' to deliver two anticancer drugs sequentially to cancer cells, with each drug targeting the distinct part of the cell where it will be most effective. The technique was found to perform better than either drug in isolation when tested in a mouse model targeting a human lung cancer tumor.
