How Spheres Become Worms: Breakthrough with NMR spectroscopy

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 ...

Exciton fission – one photon in, two electrons out

Exciton fission could be extremely useful for high-efficiency photovoltaics

24-Apr-2023 - Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are quantized, meaning they come in tiny packets called photons and electrons. In a solar cell, the energy ...
