Researchers have developed a process for the photocatalytic degradation of these pollutants when they flow through polymer membranes. Irradiation with light triggers a chemical reaction, as a result of which steroid hormones are degraded on the membranes coated with titanium dioxide.
Researchers have developed a new measurement and imaging approach that can resolve nanostructures smaller than the diffraction limit of light without requiring any dyes or labels.
Propelling micrometre-sized drones using light only and exerting precise control: Physicists have succeeded at this for the first time. Their microdrones are significantly smaller than red blood cells.
Solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in the terahertz range, researchers have now solved the puzzle of how these temporal links are formed.
