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 »


Mysteries of the Fish Fin Revealed

The rayed structure of the fin is found in greater than 99% of all living fish species – a testament to its versatility. Among many other maneuvers, fish use it to stay still in moving waters, or to propel themselves in explosive bursts of motion. The fins themselves are mechanically...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 »


“Body on a chip” could improve drug evaluation

Human tissue samples linked by microfluidic channels replicate interactions of multiple organs.

MIT engineers have developed new technology that could be used to evaluate new drugs and detect possible side effects before the drugs are tested in humans. Using a microfluidic platform that connects engineered tissues from up to 10 organs,...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 »


Replicate body parts with 3D printing

A new 3D printing technique allows researchers to replicate biological structures, which could be used for tissue regeneration and replica organs.

Imperial College London researchers have developed a new method for creating 3D structures using cryogenics (freezing) and 3D printing techniques.

This builds on previous...Read More »


Wear particles from underground railways are dangerous for your health

Nearly 90 percent of the 4.5 million workers in the Los Angeles area spend an average of 60 minutes each day commuting on a roadway or railway, according to the U.S. Census Bureau.

When researchers from the USC Viterbi School of Engineering set out to study the...Read More »


Our hairy insides

Engineers predict how flowing fluid will bend tiny hairs that line blood vessels and intestines.

Our bodies are lined on the inside with soft, microscopic carpets of hair, from the grassy extensions on our tastebuds, to fuzzy beds of microvilli in our stomachs, to superfine protein strands throughout our blood vessels....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 »


White Fingers Deseases detected with Thermal Camera

Using a thermal camera, scientist Katarina Leijon Sundqvist succeeds, in a quick and simple way, to study differences in blood circulation in the hands of people who suffer from Raynaud’s phenomenon, also known as “white fingers”, and those who do not suffer from this phenomenon.

Blood circulation and the heat exchange...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 »

Lubricating industry naturally

Sesame oil might make a viable and sustainable alternative to mineral oil as an industrial lubricant, according to research published in the International Journal of Agricultural Resources, Governance and Ecology.

Sabarinath Sankaran Nair, Kumarapillai Prabhakaran Nair, and Perikinalil Krishnan Rajendrakumar of the Department of Mechanical Engineering at...Read More »


All mighty friction shapes zebrafish embryos

A simple ball of cells is the starting point for humans – and zebrafish. At the end of embryonic development, however, a fish and a human look very different. The biochemical signals at play have been studied extensively. How mechanical forces on the other hand shape the embryo is the...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 »
