Cartilage degeneration is due to osteoarthritis (OA) which is commonly seen in aging populations. This degeneration occurs due to the deterioration of the mechanical and tribological properties of articular cartilage (AC), primarily caused by lubrication […]
Introduction Prosthetic devices make a significant difference in people’s lives by restoring mobility. However, during regular use, these devices produce small particles called wear debris. It’s important to understand the impact of wear debris as […]
Introduction According to American Heart Association’s 2017 Heart Disease and Stroke Statistics Update, nearly 801,000 deaths in the US had cardiovascular disease as the underlying cause of death. That’s about 1 of every 3 deaths […]
Human red cells (RBCs) are very versatile and have the ability to experience cell deformation as they move around different small vessels and capillaries. Their average life time is around 120 days and during this […]
This is a summary of International Workshop: Contact Mechanics and Friction – Foundations and Applications that was organized by Professor Popov and his group at TU Berlin on 13-17 October 2019. The workshop held this […]
Scientists from the Johannes Gutenberg University Mainz are studying the tooth enamel surface of lepidosauria. Lepidosauria are reptiles with overlapping scales and include approximately 7150 species of lizards, snakes, tuatara and amphisbaenians (worm lizards). The […]
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 […]
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 […]
