Scientists seek new physics using ORNL's intense neutrino source
Soon to be deployed at the Department of Energy's Oak Ridge National Laboratory is an experiment to explore new physics associated with neutrinos. The Precision Oscillation and Spectrum Experiment, or PROSPECT, is led by Yale University and includes partners from 14 academic and governmental institutions. The DOE High Energy Physics program will support the experiment at the High Flux Isotope Reactor (HFIR), a DOE Office of Science User Facility at ORNL.

Innovative device allows 3-D imaging of the breast with less radiation
Adding a new device to an existing breast molecular imaging system allows the system to get six times better contrast of cancer lesions in the breast, providing the same or better image quality while also potentially reducing the radiation dose to the patient by half. The device may also allow for 3-D molecular breast images at higher resolution than current 2-D scans in a format that may be used alongside 3-D digital mammography.

Neutrons reveal unexpected magnetism in rare-earth alloy
Researchers at the Department of Energy's Oak Ridge National Laboratory and their collaborators used neutron scattering to uncover magnetic excitations in the metallic compound ytterbium-platinum-lead. Surprisingly, this three-dimensional material exhibits magnetic properties that one would conventionally expect if the connectivity between magnetic ions was only one-dimensional. A better understanding of those behaviors could lead to applications in quantum computing and improved storage device technologies.

DNA shaping up to be ideal framework for rationally designed nanostructures
Scientists developed two DNA-based self-assembly approaches for desired nanostructures. The first approach allows the same set of nanoparticles to be connected into a variety of three-dimensional structures; the second facilitates the integration of different nanoparticles and DNA frames into interconnecting modules, expanding the diversity of possible structures. These approaches could enable the rational design of nanomaterials with enhanced or combined optical, electric, and magnetic properties to achieve desired functions.

New material has potential to cut costs and make nuclear fuel recycling cleaner
Researchers are investigating a new material that might help in nuclear fuel recycling and waste reduction by capturing certain gases released during reprocessing more efficiently than today's technology. The metal-organic framework captures radioactive gases xenon and krypton at ambient temperature, eliminating an energy-intensive, expensive step.

New mathematics accurately captures liquids and surfaces moving in synergy
A new mathematical framework developed at Berkeley Lab, published in the June 10, 2016 issue of Science Advances, allows researchers to capture fluid dynamics coupled to interface motion at unprecedented detail. The framework, called 'interfacial gauge methods', developed by Robert Saye, a Luis W. Alvarez Fellow in the Mathematics Group at Berkeley Lab, rewrites the equations governing incompressible fluid flow in a way that is more amenable to accurate computer modeling.

Scientists find surprising magnetic excitations in a metallic compound
Scientists have found magnetic excitations in a metallic compound whose main source of magnetism is the orbital movement of its electrons. Their discovery challenges conventional wisdom that these excitations are only found in materials whose magnetism is dominated by the spin of its electrons.

Physicist Fatima Ebrahimi at the US Department of Energy's Princeton Plasma Physics Laboratory and Princeton University has for the first time performed computer simulations indicating the efficiency of a start-up technique for doughnut-shaped fusion machines known as tokamaks. The simulations show that the technique, known as coaxial helicity injection, could also benefit tokamaks that use superconducting magnets.

Better combustion for power generation
As US utility companies replace coal-fired power plants with natural gas, a collaboration between GE and Oak Ridge National Laboratory is contributing to efficiency gains in GE's H-class gas turbines. GE researchers produced the first simulation involving multiple gas turbine combustors to study combustion interactions that are impractical to test physically. Advanced simulation is projected to results in a full percentage-point gain in turbine efficiency.

Neutrons probe structure of enzyme critical to development of next-generation HIV drugs
A team led by the Department of Energy's Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS. The enzyme, known as HIV-1 protease, is a key drug target for HIV and AIDS therapies. The multi-institutional team used neutron crystallography to uncover detailed interactions of hydrogen bonds at the enzyme's active site, revealing a pH-induced proton 'hopping' mechanism that guides its activity.

Thinning out the carbon capture viscosity problem
Researchers have used computer modeling to design carbon dioxide binding materials so that they retain a low viscosity after sponging up carbon dioxide, based on a surprise they found in their explorations. Although the chemists still have to test the predicted liquid in the lab, being able to predict viscosity will help researchers find and design cheaper, more efficient carbon capture materials, they report in Journal of Physical Chemistry Letters.
