Precision experiment first to isolate, measure weak force between protons, neutrons

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

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. Through a unique neutron experiment at Oak Ridge National Laboratory, experimental physicists resolved the weak force between the particles at the atom's core, predicted in the Standard Model that describes the elementary particles and their interactions.

Neutron micelle measurements lend insights into improved drug delivery

DOE/Oak Ridge National Laboratory

Researchers from the University of Houston are using neutron scattering at ORNL to research how unique biological structures known as micelles can make drugs more effective. Micelles can form around drug molecules in order to transport them through the human body. To make micelles better at transporting these molecules, the researchers are investigating how micelles are affected by the molecules they transport.

Timken turns to neutrons to get its bearings on internal stresses

DOE/Oak Ridge National Laboratory

Researchers from the Timken Company, a leading international manufacturer of bearings, are using neutron scattering at ORNL's High Flux Isotope Reactor to investigate how internal residual stresses can shorten the lifetime and reliability of a bearing. By mapping the stresses in these bearings, the researchers can develop computational models to learn how to reduce the amount of stress in future bearings.

Good vibrations: Neutrons lend insight into acoustic fracking

DOE/Oak Ridge National Laboratory

Hydraulic fracturing taps hard-to-reach pockets of oil and natural gas where more traditional drilling methods fall short. However, the process requires large amounts of water and chemicals, which can negatively impact public health and the environment. Researchers at Oak Ridge National Laboratory are using a combination of neutron and x-ray scattering to make the process safer and more efficient.

City of Knoxville demonstrates new precision de-icing technology developed by ORNL

DOE/Oak Ridge National Laboratory

The City of Knoxville, Tenn., public service crews demonstrated a new de-icing device made possible by the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville. The technology aims to more efficiently and effectively regulate brine distribution on the road during snowy weather.
