Fresh, direct evidence for tiny drops of quark-gluon plasma

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

A new analysis of data from the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) reveals fresh evidence that collisions of even very small nuclei with large ones might create tiny specks of a quark-gluon plasma (QGP). Scientists believe such a substance of free quarks and gluons, the building blocks of protons and neutrons, permeated the universe a fraction of a second after the Big Bang.

ORNL partnership with EPB tests new method for protecting quantum networks

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Researchers at the Department of Energy’s Oak Ridge National Laboratory joined forces with EPB of Chattanooga and the University of Tennessee at Chattanooga to demonstrate the first transmission of an entangled quantum signal using multiple wavelength channels and automatic polarization stabilization over a commercial network with no downtime.

The successful trial of this innovation marks another step toward the eventual creation of a quantum internet that could prove to be more capable and secure than existing networks.

Unlocking the potential of lithium-sulfur batteries

DOE/Argonne National Laboratory
Peer-Reviewed Publication

Argonne researchers have developed a new class of electrolyte additives for lithium-sulfur batteries, improving battery performance by suppressing the unwanted migration of polysulfide ions and reducing the uneven distribution and occurrence of chemical reactions within the system.

Pioneering new tool will spur advances in catalysis

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Catalysts do several surprising things to assist with daily life – from bread making to turning raw materials into fuels more efficiently. Now, SLAC researchers have developed a way to speed up the discovery process for a promising new class of these helpful substances called single atom catalysts.

Milestone 10-GeV experiment shines light on laser-plasma interactions

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

With dual lasers, researchers at the Berkeley Lab Laser Accelerator Center accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters. The experiment gives scientists a “frame-by-frame” look at how a petawatt laser interacts with a long plasma channel, knowledge that’s crucial for building future compact particle accelerators.
