A talk by Professor Bo Persson on contact mechanics and adhesion in biological systems. Abstract: One of the weakest forces in nature is the van der Waals interaction which acts between all atoms and solids. […]
Researchers at KTH have produced a bio-based material that is reported to surpass the strength of all known bio-based materials whether fabricated or natural, including wood and spider silk. Working with cellulose nanofibre (CNF), the […]
Research sheds light on friction, lubrication and wear in cartilage 11:25 a.m., Aug. 24, 2015–Osteoarthritis, which affects some 27 million people in the U.S. alone, occurs when the protective cartilage on the ends of bones […]
They’re yellow. They’re radioactive. And they’re very slippery. Yes, they’re bananas, and we have just found out why they’re so slippery. So yellow … yes we all know that. But radioactive? Well yes, bananas are […]
Gecko hanging on glass by one foot Travis Hagey, Michigan State University evolutionary biologist, shows how different groups of lizards – geckos and anoles – took two completely different evolutionary paths to developing the beneficial […]
The characteristics of human skin are heavily dependent on the hydration of the tissue – in simple terms, the water content. This also changes its interaction with textiles. Up to now, it has only been […]
What is friction? There is more than one definition of friction. And this has confused our understanding of how it is involved in friction blister formation. The Merriam-Webster Dictionary has two definitions of friction: the act of […]
NOT LONG BEFORE MY LAST SKI TRIP, I was having a lot of lower back problems stemming from a bad fall years ago. Without getting into too much blood and gore, I have a pinched […]
Superlubricity is a state of vanishing sliding friction. It has been reported in glycerol/water mixture lubricated contacts, graphene-gold interface, interface in presence of graphene and in other conditions. Increasing number of reports on superlubricity in […]
Superlubricity is a state of low friction, broadly defined as the state with the coefficient of friction lower than 0.01. This level is not achievable with classical lubrication mechanisms and currently other methods are being […]
