Tribology to analyze wine mouthfeel

Researchers at the University of California, Davis, are investigating whether an analytical technique to measure friction between two surfaces can provide better understanding of wine sensory perception related to astringency and mouthfeel.

Mouthfeel is an important sensory characteristic in consumer perception related to wine quality and enjoyment,...Read More »

Serendipitous discovery may lead to eco-friendly lubricant

Seed oil components of an ornamental flower could provide a direct pathway for designing a new class of environmentally friendly lubricants. Researchers at the School of Science at IUPUI identified the compound in the seed oil that is produced in a manner unlike any other fatty acid. The...Read More »

Snake skin inspired texture to control friction

If you want to know how to make a sneaker with better traction in the rain, just ask a snake. That’s the theory driving the research of Hisham Abdel-Aal, PhD, an associate teaching professor from Drexel University’s College of Engineering who is...Read More »

Cartilage tribology: Slip sliding away

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 wears down over time.

The availability of artificial cartilage would be life changing for those suffering from...Read More »

Artificial gelatin-based skin model that simulates human skin almost perfectly

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 possible to determine the interaction between human skin and textiles by means of clinical trials...Read More »

Feeling of a touch for robots through artificial intelligence and contact area patterns

Eight years ago, Ted Adelson’s research group at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) unveiled a new sensor technology, called GelSight, that uses physical contact with an object to provide a remarkably detailed 3-D map of its surface.

Now, by mounting GelSight sensors on the grippers of robotic arms,...Read More »

Superlubricity with Green Lubricant

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 macroscale is driven by the need of energy costs...Read More »


Brasenia schreberi mucilage - superlubric biological liquid

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 searched for. Existing methods of superlubricity require specific conditions, material combinations or limited to...Read More »

Reduced Friction: Inspired by Nature

Darvin’s theory of evolution is widely held concept which states that all the life has evolved from a common ancestor: fruits, animals, trees, flowers. During the gradual process of evolution, beneficial random genetic mutations in simple creatures accumulated and resulted in more complex species. The process of accumulation of only...Read More »
