'Whiskey webs' are the new 'coffee ring effect'

Spilled coffee forms a ring as the liquid evaporates, depositing solids along the edge of the puddle. This "coffee ring effect" has fascinated scientists for decades, but now a team says they have uncovered the mechanism ...

Wetting property of Li metal with graphite

The "Rock-chair" Li-ion battery (LIB) was discovered in the late 1970s and commercialized in 1991 by Sony, which has become the primary way we store portable energy today. To honor the contribution for "creating a rechargeable ...

Clouds on Jupiter rising up above the surrounding atmosphere

Though it looks like it to us, Jupiter's clouds do no form a flat surface. Some of its clouds rise up above the surrounding cloud tops. The two bright spots in the right center of this image are much higher than the surrounding ...

Modeling a model nanoparticle

Metal nanoparticles have a wide range of applications, from medicine to catalysis, from energy to the environment. But the fundamentals of adsorption—the process allowing molecules to bind as a layer to a solid surface—in ...

Robot traps ball without coding

Dr. Kee-hoon Kim's team at the Center for Intelligent & Interactive Robotics of the Korea Institute of Science and Technology (KIST) developed a way of teaching "impedance-controlled robots" through human demonstrations using ...

Peering into plasma mirrors

When light interacts with a mirror which is moving towards it at a speed close to the speed of light, its wavelength is shifted into the extreme ultraviolet region of the spectrum. This effect was first predicted by Albert ...
