Oak Ridge National Laboratory develops liquid helium auto-fill technology

OAK RIDGE, Tenn., May 14, 2019—Advanced Research Systems, Inc., has licensed a technology designed to automatically refill liquid helium used in laboratory equipment for low-temperature scientific experiments, which will reduce downtime, recover more helium and increase overall efficiency.

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.

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.

New 3D maps of water distribution during cellular membrane fusion are accelerating scientific understanding of cell development, which could lead to new treatments for diseases associated with cell fusion. Using neutron diffraction at the Department of Energy’s O...
As protons (pink) strike the target vessel and pass into the liquid mercury inside, the protons are absorbed, creating neutrons (blue) that are then sent through moderators and beam tubes to research instruments to study the fundamental properties of mate
The Spallation Neutron Source at the Department of Energy’s Oak Ridge National Laboratory has reached a new milestone by operating a complete neutron production run cycle at 1.3 megawatts. Achieving the record power level with a remarkable 94 percent accelerator bea...

Led by the University of Manchester, an international team of scientists has developed a metal-organic framework material (MOF) that exhibits a selective, fully reversible and repeatable capability to remove nitrogen dioxide gas from the atmosphere in ambient conditions.

Neutron interactions revealed the orthorhombic structure of the hybrid perovskite stabilized by the strong hydrogen bonds between the nitrogen substituent of the methylammonium cations and the bromides on the corner-linked PbBr6 octahedra.
Neutron scattering has revealed, in real time, the fundamental mechanisms behind the conversion of sunlight into energy in hybrid perovskite materials. A better understanding of this behavior will enable manufacturers to design solar cells with increased efficiency...
