World's smallest fidget spinner showcases access to serious science facility

DOE/Oak Ridge National Laboratory

One drop of liquid, a cutting-edge laser 3-D-printer and a few hours are all it takes to make a fidget spinner smaller than the width of a human hair. The tiny whirligig was created by researchers at Oak Ridge National Laboratory's Center for Nanophase Materials Sciences to illustrate the facility's unique resources and expertise available to scientists across the world. The microscale fidget spinner measures only 100 microns wide, or one tenth of a millimeter.

Grant and Award Announcement

Researchers at the Department of Energy's Oak Ridge National Laboratory have received nine R&D 100 Awards in recognition of their significant advancements in science and technology.

Cyanobacterial studies examine cellular structure during nitrogen starvation

DOE/Oak Ridge National Laboratory

Researchers from Washington University in St. Louis and ORNL are using neutrons to study what happens when cyanobacteria cell samples are starved for nitrogen. They are especially interested in how this process affects phycobilisomes, large antenna protein complexes in the cells that harvest light for photosynthesis.

INCITE grants of 5.95 billion hours awarded to 55 computational research projects

DOE/Oak Ridge National Laboratory
Grant and Award Announcement

The US Department of Energy's Office of Science announced 55 projects with high potential for accelerating discovery through its Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program. The projects will share 5.95 billion core-hours on three of America's most powerful supercomputers dedicated to capability-limited open science and support a broad range of large-scale research campaigns from infectious disease treatment to next-generation materials development.

Neutrons probe oxygen-generating enzyme for a greener approach to clean water

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A new study sheds light on a unique enzyme that could provide an eco-friendly treatment for chlorite-contaminated water supplies and improve water quality worldwide. An international team of researchers used neutron analysis at Oak Ridge National Laboratory, X-ray crystallography and other techniques to study chlorite dismutase, an enzyme that breaks down the environmental pollutant chlorite into harmless byproducts. Their results advance understanding of the catalytic process involved to support future applications in bioremediation and biotechnology.

Resisting the resistance: Neutrons search for clues to combat bacterial threats

DOE/Oak Ridge National Laboratory

Researchers from ORNL's Neutron Sciences Directorate are conducting a series of experiments to better understand how resistant bacteria use enzymes called beta-lactamases to break down the beta-lactam class of antibiotics.

Neutron spectroscopy reveals common 'oxygen sponge' catalyst soaks up hydrogen too

DOE/Oak Ridge National Laboratory

Having the right tool for the job enabled scientists at the Department of Energy's Oak Ridge National Laboratory and their collaborators to discover that a workhorse catalyst of vehicle exhaust systems -- an 'oxygen sponge' that can soak up oxygen from air and store it for later use in oxidation reactions -- may also be a 'hydrogen sponge.' The finding may pave the way for the design of more effective catalysts for selective hydrogenation reactions.
