New thermoelectric material delivers record performance

Taking advantage of recent advances in using theoretical calculations to predict the properties of new materials, researchers reported Thursday the discovery of a new class of half-Heusler thermoelectric compounds, including ...

Scientists form flat tellurium

In the way things often happens in science, Amey Apte wasn't looking for two-dimensional tellurium while experimenting with materials at Rice University. But there it was.

Reinventing metal 3-D printing with new direct writing process

Metal 3-D printing has enormous potential to revolutionize modern manufacturing. However, the most popular metal printing processes, which use lasers to fuse together fine metal powder, have their limitations. Parts produced ...

Arctic melt ponds form when meltwater clogs ice pores

When spring comes to the Arctic, the breakup of the cold winter ice sheets starts at the surface with the formation of melt ponds. These pools of melted snow and ice darken the surface of the ice, increasing the amount of ...

Melting solid below the freezing point

Phase transitions surround us—for instance, liquid water changes to ice when frozen and to steam when boiled. Now, researchers at the Carnegie Institution for Science have discovered a new phenomenon of so-called metastability ...
