Think you’ve seen big rings in our own solar system? Not even close. When the University of Rochester’s Eric Mamajek tells other astronomers about the object he and his colleagues discovered about 430 light-years from Earth, they tend to be skeptical–very skeptical.
“This planet is much larger than Jupiter or Saturn, and its ring system is roughly 200 times larger than Saturn’s rings are today,” co-author Eric Mamajek, professor of physics and astronomy at the University of Rochester, said in a statement. “You could think of it as kind of a super Saturn.”
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.
