The observation of an abnormal state of matter in a two-dimensional magnetic material is the latest development in the race to harness novel electronic properties for more robust and efficient next-generation devices.

The Weyl semimetal state is induced when the opposing motions of the
electrons cause the Dirac cones to split in two (illustrated on the left by
outward facing electrons, opposite the inward

The Spallation Neutron Source marks a decade as a leading neutron science facility today at the Department of Energy's Oak Ridge National Laboratory.

Members of the Shull and Wollan families came to ORNL on September 22, 2016 to
participate in a ceremony dedicating the renamed Shull Wollan Center--a Joint Institute
for Neutron Science, recognizing two scientists who pioneered a field of

In fact, Haberl can identify the specific instance, early in her career, when that excitement originated and guided her toward high pressure science. It was her first time

Advances in modern electronics has demanded the requisite hardware, transistors, to be smaller in each new iteration. Recent progress in nanotechnology has reduced the size of silicon transistors down to the order of 10 nanometers. However, for such small transistors, other physical effects set in, which limit their functionality. For example, the power consumption and heat production in these devices is creating significant problems for device design. Therefore, novel quantum materials and device concepts are required to develop a new generation of energy-saving

Scientists at the Department of Energy’s Oak Ridge National Laboratory have performed neutron structural analysis of a vitamin B6-dependent protein, potentially opening avenues for new antibiotics and drugs to battle diseases such as drug-resistant tuberculosis, malaria and diabetes.

An ORNL-led team used neutrons to observe the AAT enzyme, a vitamin B6-dependent
protein, and found

A team led by the Department of Energy’s Oak Ridge National Laboratory has used sophisticated neutron scattering techniques to detect an elusive quantum state known as the Higgs amplitude mode in a two-dimensional material.

The ORNL-led research team selected a crystal composed of copper bromide –
because the copper ion is ideal for studying exotic quantum effects –
to observe the elusive Higgs amplitude

Producing biofuels like ethanol from plant materials requires various enzymes to break down the cellulosic fibers. Scientists using neutron scattering have identified the specifics of an enzyme-catalyzed reaction that could significantly reduce the total amount of enzymes used, improving production processes and lowering costs.

A combination of X-ray and neutron scattering has revealed new insights into how a
Neutron scattering is a valuable technique for studying cell membranes, but signals from the cell’s other components such as proteins, RNA, DNA and carbohydrates can get in the way. An ORNL team made these other components practically invisible to neutron

OAK RIDGE, Tenn., May 24, 2017—A research team from the Department of Energy’s Oak Ridge National Laboratory has performed the first-ever direct nanoscale examination of a living cell membrane. In doing so, it also resolved a long-standing debate by identifying tiny groupings of lipid molecules that are likely key to the cell’s functioning.

Neutron scattering is a valuable technique for studying cell membranes, but
