Gels are materials composed of a three-dimensional crosslinked polymer or colloidal network immersed in a fluid. They are usually soft and weak, but can be made hard and tough. Hydrogels are gels ...

"Blue balls" is a slang term for a medical condition called epididymal hypertension. This condition occurs when prolonged sexual arousal without ejaculation causes fluid to build up in the testicles.

Researchers from Aalto University and the University of Bayreuth have unveiled a groundbreaking self-healing hydrogel that mimics human skin. This cutting-edge material repairs itself up to 90% in ...

The hydrogel has around 10,000 layers of nanosheets in a sample that is one millimeter thick, allowing it to achieve stiffness akin to human skin while enabling it to stretch. Nature-inspired ...

A research team from Aalto University and the University of Bayreuth has now overcome this limitation. They have developed a hydrogel with a unique structure that combines strength and self-repair, ...

Now, a team of researchers from Aalto University and the University of Bayreuth are the first to develop a hydrogel with a unique structure that overcomes earlier limitations, opening the door to ...

The hydrogel has a unique structure, making it the first to combine strength and flexibility with self-healing capabilities. We all encounter gels in daily life – from the soft, sticky ...
