Metasurfaces: Tiny tech with big potential

Imagine manipulating light with ultra-thin, flat sheets instead of bulky lenses and mirrors. That's the promise of metasurfaces, a nanostructure technology that can twist and bend light in ways never before possible.

Illuminating the unavoidable imperfections of nanostructures

A new study by a collaborative team from the University of Twente and the e-Science Center in Amsterdam compares the transmission of light through a utopian model with a real 3D nanostructure. These nanostructures are integral ...

Nanoplastics put stress on trees and impair photosynthesis

It is well known that more and more plastic waste is ending up in soil and bodies of water. Researchers are particularly concerned about tiny micro- and nano-sized particles. It remains unclear how and to what extent they ...

Cleaning water with 'smart rust' and magnets

Pouring flecks of rust into water usually makes it dirtier. But researchers have developed special iron oxide nanoparticles they call "smart rust" that actually makes it cleaner. Smart rust can attract many substances, including ...
