Materials follow the 'Rule of Four,' but scientists don't know why yet

Scientists are normally happy to find regularities and correlations in their data—but only if they can explain them. Otherwise, they worry that those patterns might just be revealing some flaw in the data itself, so-called ...

Thermal properties of new 2D materials for microchips can now be measured well

Making ever smaller and more powerful chips requires new ultrathin materials: 2D materials that are only 1 atom thick, or even just a couple of atoms. Think about graphene or ultra-thin silicon membrane for instance.

Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation

Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species ...

Two-dimensional nanomaterial sets expansion record

It is a common hack to stretch a balloon out to make it easier to inflate. When the balloon stretches, the width crosswise shrinks to the size of a string. Noah Stocek, a Ph.D. student collaborating with Western physicist ...

Vibrations of granular materials: Theoretical physicists shed light on an everyday scientific mystery

Coffee beans in a jar and piles of rice or sand are examples of granular matter: materials composed of large numbers of macroscopic—rather than atomic scale—particles. Although granular matter is extremely familiar in ...

Study shows copper beads in pig feed reshape swine gut microbiome

Copper is a natural antimicrobial material that, when added to pig feed, may promote the growth and health of the animals. Since pigs can tolerate high levels of the metal, researchers at Texas Tech University in Amarillo ...

Peptides on interstellar ice: Study finds presence of water molecules not a major obstacle for formation

A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. ...
