Specific interactions cause spherical nanoparticles of polymers to rearrange themselves into worm-like structures during cooling. The resulting hydrogel dissolves again when heated.

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

A honeybee (Apis mellifera) collects honeydew on a fir tree. The study shows that the beech-dominated Steigerwald provides insufficient food resources for honeybees.

What role do forests play as a feeding habitat for honeybees? A team led by Würzburg biologist Dr. Benjamin Rutschmann investigated this question. For this purpose, the researchers used observation hives inside the Steigerwald.

Illustration of exciton splitting in the organic semiconductor pentacene, which consists of five benzene rings each. Instead of the usual two free charge carriers, absorption of a photon in pentacene generates four free charge carriers, represented by orange tracks.

Some materials convert photons into more free charges than would be expected. Using an ultrafast film, researchers have now been able to get a picture of this process. Physicists from the University of Würzburg were also involved.

Flower strips are the focus of a Europe-wide research project involving scientists from the University of Würzburg.

Can flower strips combined with hedges improve biodiversity in intensively used agricultural areas? This is what a team from the University of Würzburg is investigating with project partners from four EU countries.
