A novel combination of microscopy and data processing has given researchers at the Department of Energy’s Oak Ridge National Laboratory an unprecedented look at the surface of a material known for its unusual physical and electrochemical properties.

It may sound strange to say that nuclear weapons must survive radiation. But as part of its mission of ensuring the nation’s stockpile is safe, secure and effective as a deterrent, Sandia National Laboratories must make sure crucial parts can function if they’re hit by radiation, especially a type called fast neutrons.

Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science.

Columbia researchers used Brookhaven Lab supercomputer simulations to map and compare the transformations and breaking points of graphene and other promising monolayers.

The warm beauty of amber was captivating and mysterious enough to inspire myths in ancient times, and even today, some of its secrets remain locked inside the fossilized tree resin. But for the first time, scientists have now solved at least one of its puzzles that had perplexed them for decades. Their report on a key aspect of the gemstone’s architecture appears in the ACS journal Analytical Chemistry.
