A team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest nucleus consisting of one neutron and one proton for the study.

Tyler Cooksey preps Bio SANS instrument for use.

To learn more about interactions between drug molecules and micelles, Associate Professor Megan Robertson and graduate students Tyler Cooksey and Tzu-Han Li from the University of Houston (UH) are using neutrons at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL).

Using as much as 50 percent lignin by weight, a new composite material created at ORNL is well suited for use in 3D printing.

Scientists at the Department of Energy’s Oak Ridge National Laboratory have created a recipe for a renewable 3D printing feedstock that could spur a profitable new use for an intractable biorefinery byproduct: lignin.

OAK RIDGE, Tenn., Nov. 27, 2018—The Spallation Neutron Source at the Department of Energy’s Oak Ridge National Laboratory has broken a new record by ending its first neutron production cycle in fiscal year 2019 at its design power level of 1.4 megawatts.

Kushol Gupta adjusts Bio SANS instrument at the High Flux Isotope Reactor.

Kushol Gupta hopes to beat HIV’s defenses. A research assistant professor from the University of Pennsylvania’s Perelman School of Medicine, Gupta recently concluded an experiment at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) he hopes will improve allosteric inhibitors of integrase (ALLINIs), a new class of HIV-fighting drug that inhibits the virus’s ability to reproduce.

ORNL researchers Todd Toops, Charles Finney, and Melanie DeBusk (left to right) hold an example of a particulate filter used to collect harmful emissions in vehicles.

Researchers are looking to neutrons for new ways to save fuel during the operation of filters that clean the soot, or carbon and ash-based particulate matter, emitted by vehicles. A team of researchers from the Energy and Transportation Science Division at the Department of En...

Using nondestructive neutron scattering techniques, scientists are examining how single-celled organisms called cyanobacteria produce oxygen and obtain energy through photosynthesis.

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

After more than a year of operation at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.
