When we first saw it happening, we were frankly in disbelief,” Dr Sushanta Mitra said. “We double-checked everything because ...

When it comes to buying tires, there are a few important parameters, one of those being rolling resistance. This one is ...

The team’s orb rolled vertically at a rate of about 0.5 millimeters per second. Regardless, Mitra and colleagues wrote that ...

Get Instant Summarized Text (Gist) A new form of superlubricity has been observed where bismuth islands move on graphite with near-zero friction, but only along specific directions. This ...

The researchers, from the University of Amsterdam and the Advanced Research Center for Nanolithography, then explored how the friction behaved when the strength with which the two surfaces are ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first ...

It was correspondingly difficult to develop a suitable measurement technique to measure the rolling friction occurring on the particle. Making a suitable holder proved to be particularly challenging. ...

A good sweater is like a cozy hug made out of yarn. For that, you can thank friction. A new study reveals how knit fabrics can take on versatile shapes that allow them to conform to the contours ...

Using biowaste from cassava plants, scientists have created a coating that virtually eliminates friction in metal parts. The breakthrough has the potential to deliver better fuel economy ...

The seeds were released, and they rolled down the inclined plane. Due to rolling friction, the seeds eventually came to rest on a horizontal surface. Schematic diagram of the method used to measure ...
