Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify chemicals and pollutants with extremely high ...
Skyrmions are localized, particle-like excitations in materials that retain their structure due to topological constraints (i.e., restrictions arising from properties that remain unchanged under smooth deformations). These ...
In nanophotonics, tiny structures are used to control light at the nanoscale and render it useful for technological applications. A key element here is optical resonators, which trap and amplify light of a certain color (wavelength).
How do left-handed and right-handed molecules differ? Researchers at ETH Zurich are using a new imaging method to visualize what was previously only measurable as an average, opening up new possibilities for biology and materials ...
A low-cost material made from clay鈥攃ommon in British soil鈥攁nd vitamin B2 could one day help clean up pollution using only sunlight.
In the push to shrink and enhance technologies that control light, MIT researchers have unveiled a new platform that pushes the limits of modern optics through nanophotonics, the manipulation of light on the nanoscale, or ...
Researchers are creating new moir茅 materials at the nanometer scale using advanced DNA nanotechnology. DNA moir茅 superlattices form when two periodic DNA lattices are overlaid with a slight rotational twist or positional ...
