Novel cell membrane model could be key to uncovering new protein properties

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Researchers have recently shed light on how cell membrane proteins could be influenced by the lipids around them. By developing a novel type of membrane model, they were able to show that the shape and behavior of a protein can be altered by exposure to different lipid compositions. The research team confirmed the artificial membrane's structure through neutron and x-ray scattering at the Department of Energy's (DOE's) Brookhaven (BNL) and Oak Ridge National Laboratories (ORNL).

Fast fabrication: ORNL develops, produces metal hydride for moderator in 3D-printed reactor

DOE/Oak Ridge National Laboratory

Researchers thought yttrium hydride would be an ideal moderator for the new Transformational Challenge Reactor, but no one had yet figured out how to produce the large, crack-free pieces needed. An ORNL scientist developed a process and invented a machine to do that -- in only 10 months.

Prometheus Fuels licenses energy-saving ORNL ethanol-to-jet-fuel process

DOE/Oak Ridge National Laboratory
Business Announcement

Prometheus Fuels has licensed an ethanol-to-jet-fuel conversion process developed by researchers at the Department of Energy's Oak Ridge National Laboratory. The ORNL technology will enable cost-competitive production of jet fuel and co-production of butadiene for use in renewable polymer synthesis.

First fiber-optic nanotip electron gun enables easier nanoscale research

DOE/Oak Ridge National Laboratory

Scientists at Oak Ridge National Laboratory and the University of Nebraska have developed an easier way to generate electrons for nanoscale imaging and sensing, providing a useful new tool for material science, bioimaging and fundamental quantum research.

Quantum light squeezes the noise out of microscopy signals

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Researchers at the Department of Energy's Oak Ridge National Laboratory used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible with traditional tools. 'We showed how to use squeezed light -- a workhorse of quantum information science -- as a practical resource for microscopy,' said Ben Lawrie, who led the research with Raphael Pooser.
