Neutron measurements at Oak Ridge National Laboratory’s Spallation Neutron Source are giving physicists new insight into the behavior of quantum magnets. A research team led by Young-June Kim from the University of Toronto used neutron spectroscopy to observe a novel type of energy band repulsion in a magnetic insulator. The study adds to scientists’ understanding

What can skyrmions do for you? These ghostly quantum rings, heretofore glimpsed only under extreme laboratory conditions, just might be the basis for a new type of computer memory that never loses its grip on the data it stores. Now, thanks to a research team including scientists from the National Institute of Standards and Technology

To understand diseases like Parkinson’s, the tiniest of puzzles may hold big answers. That’s why a team including scientists from the National Institute of Standards and Technology (NIST) have determined* how two potentially key pieces of the Parkinson’s puzzle fit together, in an effort to reveal how the still poorly understood illness develops and affects

In a paper published in Structure, a team led by the U.S. Department of Energy’s Oak Ridge National Laboratory reported the pioneering use of neutron and X-ray crystallography and high performance computing to study how the enzyme D-xylose isomerase, or XI, can cause a biochemical reaction in natural sugar to produce rare sugars. Unlike drugs made

A team from Oak Ridge National Laboratory and the University of Tennessee studied carbon fibers made from lignin, a woody plant polymer known as, and found a mixture of perfectly spherical nanoscale crystallites distributed within a fibrous matrix. They found the lignin fiber’s unique structure could make it useful as a battery anode, potentially improving

Neutron scattering research at the Department of Energy’s Oak Ridge National Laboratory has revealed clear structural differences in the normal and pathological forms of a protein involved in Huntington’s disease. Huntington’s disease, an incurable neurodegenerative disorder, starts as a genetic mutation that leads to an overabundance of “huntingtin” protein fragments, which form clumps in the

Neutron scattering and heat capacity techniques were used to investigate two frustrated magnets with similar structure, but different sized spins (S).The research team, led by McMaster University, found the molybdate pyrochlore oxide material, Lu2Mo2O7 (S=1) undergoes a transition to a spin glass ground state, while the oxynitride Lu2Mo2O5N2 (S=1/2) possesses a quantum spin liquid ground

A team led by the U.S. Department of Energy’s Oak Ridge National Laboratory has unlocked the enzymatic synthesis process of rare sugars, which are useful in developing drugs with low side effects using a process more friendly to the environment. In a paper published in Structure, the research team reported the pioneering use of neutron

Inelastic neutron scattering experiments reveal that the effective magnetic exchange couplings in NaFeAs are smaller and more isotropic than those in the heavily studied AFe2As2 family. These results provide evidence that the energy scale of the magnetic excitations, which are thought to influence the superconducting transition temperature, is controlled by the position of As atoms

The complex, nonlinear flow behavior of soft materials transcends industrial applications, smart material design and non-equilibrium thermodynamics. A long-standing, fundamental challenge in soft-matter science is establishing a quantitative connection between the deformation field, local microstructure and macroscopic dynamic flow properties i.e., the rheology. Here, a new experimental method is developed using simultaneous small angle neutron
