Mathematicians and mechanical engineers from EPFL have collaborated to gain better insights into the mechanics and geometry of two filaments in contact—as is the case of woven fabrics and knots.
Researchers from China have come up with a highly reliable thermal power generator that integrates triboelectric effect and thermoacoustic effect.
As the Mars Perseverance Rover of NASA continues to investigate the surface of the planet Mars, researchers on Earth have designed a novel nanoscale metal carbide that could serve as a “superlubricant” to decrease wear and tear on upcoming extraterrestrial rovers.
Wear and friction are crucial issues in many industrial sectors: What happens when one surface slides across another? Which changes must be expected in the material? What does this mean for the durability and safety of machines?
An innovative addition to wearers’ wardrobe may soon help them to turn on the lights and music, while simultaneously keeping them fresh, fashionable, safe, dry, and clean from the new virus that is going around.
A sneaker that has better traction even in the rain can be made by taking cues from snakes. This is the concept behind new research that analyzes snakeskin to assist engineers in enhancing the design of textured surfaces, such as prosthetic joints and engine cylinder liners.
At present, scientists have unearthed greater details on the way specific materials store a charge even after the separation of two surfaces.
An active variable stiffness vibration isolator has been developed by researchers from HRL Laboratories’ Sensors and Materials Laboratory. This isolator is capable of millisecond actuation times and 100x stiffness changes, independent of the static load. In the words of Principal Investigator Christopher Churchill, “This performance surpasses existing mechanisms by at least 20 times in either speed or useful stiffness change."
It is possible to make liquids slide over a solid surface, similar to a bobsleigh on ice, as discovered in research conducted by physicists from Saarland University and the ESPCI in Paris. A coating applied at the boundary between the solid surface and the liquid induces the liquid to slide through. The sliding effect increases the liquid’s average flow velocity and its throughput.
Harper International, world leader in thermal processing solutions for advanced materials, was recently awarded a contract for a Pusher furnace line with KEPCO Nuclear Fuel (KNF).
