Cartilage Lubrication
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 failure. Understanding the causes of...
Implant Wear Debris and Adverse Reactions
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 it can cause harmful reactions...
Tribology of Cardiac Implants
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 in the US [1]. Cardiovascular...
New method reveals how damage occurs in human biological cells due to mechanical fatigue
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 time, RBCs experience cyclic stretching...
From the Climate Change to the Atomic Scale Friction: Contact Mechanics Workshop Summary
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 year was a special one...
Tribology in Animal World: Dietary Habits of Lepidosauria Studied via Dental Microwear
[caption id="attachment_32855" align="aligncenter" width="300"] Image Source[/caption] 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)....
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...
Medical textiles and tribology
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 nerve and the associated arthritis...
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, [math] DLC - SiO_2 [/math] interface in presence of graphene and in other conditions. Increasing number of reports on superlubricity in...
