Improving lasers with microring mirrors
Team develops new water splitting technique that could produce hydrogen fuel
A University of Colorado Boulder team has developed a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the ...
How to test the twin paradox without using a spaceship
Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin ...
Researchers demonstrate proof of creation of a mirror by optical matter
Anti-mirror optical illusion could increase LED luminosity and laser power
New measurement of electron–quark scattering
From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the ...
New method of producing stereoisomers developed
Mathematician designs event cloaking device without using metamaterials
Light, instead of electrodes, could control deformable mirrors
Math professor's side mirror that eliminates 'blind spot' receives US patent
A side mirror that eliminates the dangerous "blind spot" for drivers has now received a U.S. patent. The subtly curved mirror, invented by Drexel University mathematics professor Dr. R. Andrew Hicks, dramatically ...
Scientists create light from vacuum
(PhysOrg.com) -- Scientists at Chalmers University of Technology have succeeded in creating light from vacuum observing an effect first predicted over 40 years ago. The results will be published tomorrow ...
Using light to identify chiral molecules for pharmaceuticals
(Phys.org) —A combination of nanotechnology and a unique twisting property of light could lead to new methods for ensuring the purity and safety of pharmaceuticals.
Researchers develop optically switchable chiral terahertz metamolecules
A multi-institutional team of researchers that included scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) has created the first artificial molecules whose chirality can be rapidly switched ...
