A previously unknown form of hydrogel formation has been elucidated: chemists found unusual interactions between polymers

02-May-2023

Hydrogels? Many people use these substances 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 the swellable material on their eyeballs – soft ...

New approach to enable measurements without strong magnetic fields

06-Sep-2022

Nuclear magnetic resonance (NMR) is an analytical tool with a wide range of applications, including the magnetic resonance imaging that is used for diagnostic purposes in medicine. However, NMR often requires powerful magnetic fields to be generated, which limits the scope of its use. Researchers ...
