Will carbon nanotubes replace indium tin oxide?
New paradigm for solar cell construction demonstrated
(Phys.org) —For solar panels, wringing every drop of energy from as many photons as possible is imperative. This goal has sent chemistry, materials science and electronic engineering researchers on a quest ...
SLAC scientists create twisted light
(Phys.org) —Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate twisted light ...
Toward a truly white organic LED: Physicists develop polymer with tunable colors
By inserting platinum atoms into an organic semiconductor, University of Utah physicists were able to "tune" the plastic-like polymer to emit light of different colors – a step toward more efficient, less ...
Raising the IQ of smart windows
Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a new material to make smart windows even smarter. The material is a thin coating of nanocrystals ...
New laser shows what substances are made of, could be new eyes for military (w/ video)
A new laser that can show what objects are made of could help military aircraft identify hidden dangers such as weapons arsenals far below.
Engineers' new metamaterial doubles up on invisibility (w/ Video)
(Phys.org) —The new material's artificial "atoms" are designed to work with a broad range of light frequencies. With adjustments, the researchers believe it could lead to perfect microscope lenses or invisibility ...
