Neutrons probed two mechanisms proposed to explain what happens when hydrogen gas flows over a cerium oxide (CeO2) catalyst that has been heated in an experimental chamber to different temperatures to change its oxidation state. The first mechanism sugges

Neutron spectroscopy reveals common ‘oxygen sponge’ catalyst soaks up hydrogen too

November 7, 2017

Having the right tool for the job enabled scientists at the Department of Energy’s 91�� and their collaborators to discover that a workhorse catalyst of vehicle exhaust systems—an “oxygen sponge” that can soak up oxygen from air an

COHERENT collaborators were the first to observe coherent elastic neutrino–nucleus scattering. Their results, published in the journal Science, confirm a prediction of the Standard Model and establish constraints on alternative theoretical models. Image c

World’s smallest neutrino detector finds big physics fingerprint

August 3, 2017

After more than a year of operation at the Department of Energy’s (DOE’s) 91�� (ORNL), the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral parti

Diamonds that deliver

February 24, 2017

It’s not enough to design new drugs. For drugs to be effective, they have to be delivered safely and intact to affected areas of the body. And drug delivery, much like drug design, is an immensely complex task.

Haslam visits ORNL to highlight state’s role in discovering tennessine

ORNL researchers have discovered a new type of quantum critical point, a new way in which materials change from one state of matter to another. Featured here are researchers Lekh Poudel (left), Andrew Christianson and Andrew May.

Neutrons and a ‘bit of gold’ uncover new type of quantum phase transition

January 19, 2017

When matter changes from solids to liquids to vapors, the changes are called phase transitions.
