Physicists demonstrate first time reversal of water waves
Friction almost vanishes in microscale graphite
Scientists investigate how ice melts below freezing due to nanowire's pressure
Snake skin inspired surfaces smash records, providing 40 percent friction reduction
Snake skin inspired surfaces smash records, providing an astonishing 40% friction reduction in tests of high performance materials.
New nanogenerator harvests power from rolling tires
A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car's rolling tire friction.
In tuning friction to the point where it disappears, technique could boost development of nanomachines
Friction is all around us, working against the motion of tires on pavement, the scrawl of a pen across paper, and even the flow of proteins through the bloodstream. Whenever two surfaces come in contact, ...
Researchers demonstrate method that reduces friction between two surfaces to almost zero at macroscopic scale
A new way to measure friction between highly ordered pyrolytic graphite materials
NASA finds friction from tides could help distant earths survive, and thrive
As anybody who has started a campfire by rubbing sticks knows, friction generates heat. Now, computer modeling by NASA scientists shows that friction could be the key to survival for some distant Earth-sized ...
How stick insects honed friction to grip without sticking
When they're not hanging upside down, stick insects don't need to stick. In fact, when moving upright, sticking would be a hindrance: so much extra effort required to 'unstick' again with every step.
New observations of a 'dust trap' around a young star solve long-standing planet formation mystery
Astronomers using the new Atacama Large Millimeter/submillimeter Array have imaged a region around a young star where dust particles can grow by clumping together. This is the first time that such a dust ...
Materials scientist creates world's toughest fiber by adding slip knot
Chaos theory helps to predict the outcome at the roulette table
At first glance, a roulette table looks like a jumble of numbers and a randomly hopping little white ball. But with a better understanding of physics and some general knowledge of the starting conditions, it ...
Giant ice avalanches on Saturn's moon Iapetus provide clue to extreme slippage elsewhere in solar system
Saturn's ice moon Iapetus has more giant landslides than any solar system body other than Mars. Measurements of the avalanches suggest that some mechanism lowered their coefficients of friction so that they ...
