Pitch black: Cosmic clumps cast the darkest shadows
(Phys.org) —Astronomers have found cosmic clumps so dark, dense and dusty that they throw the deepest shadows ever recorded. Infrared observations from NASA's Spitzer Space Telescope of these blackest-of-black ...
Researchers use light to dope graphene boron nitride heterostructures
(Phys.org) —Graphene continues to reign as the next potential superstar material for the electronics industry, a slimmer, stronger and much faster electron conductor than silicon. With no natural energy ...
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 ...
