Artificial skin sweats on command

Following the breakthrough with their first sweating artificial skin two years ago, Danqing Liu's multidisciplinary team hasn't been sitting still. Their goal: an artificial skin that sweats as naturally as possible. They ...

Triggering microscale self-assembly using light and heat

Self-assembly is the spontaneous organization of building blocks into structures or patterns from a disordered state. Everyday examples include the freezing of liquids or the crystallization of salts. These self-assembly ...

Toward 4D printing with structural colors

The colors in the world around us are produced through either absorption of light by molecules (pigmentary colors) or scattering of light by nanostructures (structural colors). Nature provides many spectacular examples of ...

New tiny sensor makes the invisible visible

A TU/e research group has developed a new near-infrared sensor that is easy to make, comparable in size to sensors in smartphones, and ready for immediate use in industrial process monitoring and agriculture. This breakthrough ...

Determining when a material becomes 'glassy'

Is it in a liquid phase or a 'glassy' phase? This question has been the subject of intense debate as physicists try to understand the behavior of so-called 'active matter'—a relatively new type of matter where particles ...

Controlling the length of supramolecular polymers

Systems made up of one supramolecular polymer are well understood, but much remains unknown for systems involving the combination of multiple supramolecular polymers, such as what affects the length of the resulting copolymers. ...
