Two scientists at the University of Rochester, Chunlei Guo and Anatoliy Vorobyev, have created a metal surface that is so hydrophobic that it makes Teflon look like superglue by comparison.
The University of Rochester’s Institute for Popular Music is getting ready to mark 50 years since The Rolling Stones released “(I Can’t Get No) Satisfaction.” We speak with director John Covach about the upcoming celebrations.
Water often damages metals, causing rust, wear and decay. Thanks to an innovative laser process, however, metal is getting its revenge.
Physicists in the US have created metal surfaces that repel water to the extent that droplets bounce away. They sculpted the surface of small pieces of platinum, titanium and brass using a very high-powered laser. The materials “self-clean” because water droplets gather dust particles before they slide away.
Scientists at the University of Rochester, New York, have created a metal that is so extremely hydrophobic that water bounces on it as if it were repelled by a magic force field.
Two University of Rochester scientists have found a way of using powerful laser beams to make metal surfaces last longer and be more suitable for a wide range of practical purposes. “We change the nature of the metal surface so that they can repel water,” said Chunlei Guo, who is a professor of optics and physics at UR.
In the intervening decades, humanity has recognized that our own climb up the ladder of technological sophistication comes with a heavy price. From climate change to resource depletion, our evolution into a globe-spanning industrial culture is forcing us through the narrow bottleneck of a sustainability crisis.
Every New Year, along with the noisemakers and champagne, self-styled financial gurus make market predictions for the coming 12 months. Armed with the same data that other gurus use in opposing arguments, they come on television as talking heads, post articles online or consume print editorial space to pontificate about what the next year will likely bring investors.
