Unusual interactions between polymers explain hydrogel formation

Many people use hydrogels without knowing it. As superabsorbents in nappies, for example, hydrogels absorb a lot of liquid. In the process, the initially dry material becomes jelly-like, but it does not wet. Some people place ...

Scientists grow optical chips in a petri dish

The modern photonics industry is constantly working on making its devices more compact, be it computing systems or sensors and lidars. For this, it is necessary to make lasers, transistors and other elements smaller. A team ...

Imaging technique shows new details of peptide structures

A new imaging technique developed by engineers at Washington University in St. Louis can give scientists a much closer look at fibril assemblies—stacks of peptides that include amyloid beta, most notably associated with ...

Scientists create UV-enabled flexible wearable technology

To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists from NTU Singapore have created a new type of light sensor that is both flexible and highly sensitive.While ...

Jumping frost crystals: Lab works toward electrostatic de-icing

If you have ever gotten up on a winter morning and thrown yourself into the arduous task of scraping frost from a windshield, a Virginia Tech lab is engaging science [IS1] that could make your life much easier. In research ...
