Unexpected friction in superfluids

21.02.2018 tribonet 233 Views
Physicists at Aalto University have discovered unexpected friction while rotating superfluid helium. Understanding the causes and effects of the friction could pave the way for explorations into the composition of neutron stars and our universe. […]

Predicting the limits of friction on metals

30.10.2017 tribonet 284 Views
Normally, bare metal sliding against bare metal is not a good thing. Friction will destroy pistons in an engine, for example, without lubrication. Sometimes, however, functions require metal on metal contact, such as in headphone jacks or […]
