New material discovery allows study of elusive Weyl fermion

Researchers at the U.S. Department of Energy's Ames Laboratory have discovered a new type of Weyl semimetal, a material that opens the way for further study of Weyl fermions, a type of massless elementary particle hypothesized ...

Nanodevice, build thyself

As we continue to shrink electronic components, top-down manufacturing methods begin to approach a physical limit at the nanoscale. Rather than continue to chip away at this limit, one solution of interest involves using ...

Trapping climate pollutant methane gas in porous carbon

As talks of global warming are once again making headlines, scientists have renewed their efforts to understand how to best limit its effects. For example, sequestrating short-lived climate pollutants, such as methane and ...

Titan helps unpuzzle decades-old plutonium perplexities

First produced in 1940, plutonium is one of the most electronically complicated elements on Earth—and because of its complexities, scientists have been struggling to prove the existence of its magnetic properties ever since.

The latest fashion: Graphene edges can be tailor-made

Theoretical physicists at Rice University are living on the edge as they study the astounding properties of graphene. In a new study, they figure out how researchers can fracture graphene nanoribbons to get the edges they ...

Keeping hydrogen from cracking metals

Metal alloys such as steel and zirconium that are used in pipes for nuclear reactors and oil fields naturally acquire a protective oxide or sulfide layer. But hydrogen penetration can lead to their breakdown and speed up ...
