How to Create Nanowires Only Three Atoms Wide with an Electron Beam

Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create some of the smallest wires ever made.

Secretary Moniz's Testimony Before the Senate Committee on Appropriations

Energy Secretary Ernest Moniz's statement to the Senate Committee on Appropriations on driving innovation through federal investments.

Discovering Diversity, One Cell at a Time

The game where one has to guess how many jelly beans or marbles can fill a jar should never be played with the cyanobacterium Prochlorococcus. By some estimates, in a single liter of water as many as 100 million cells of this tiny bacterium can be found. These important organisms serve as the base of the ocean food chain and are thought to be responsible for providing about 20% of the oxygen produced by the planet each year.

‘Double-duty’ Electrolyte Enables New Chemistry for Longer-lived Batteries

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a new and unconventional battery chemistry aimed at producing batteries that last longer than previously thought possible.

Scientists Watch High-temperature Superconductivity Emerge out of Magnetism

Scientists at SLAC National Accelerator Laboratory and Stanford University have shown for the first time how high-temperature superconductivity emerges out of magnetism in an iron pnictide, a class of materials with great potential for making devices that conduct electricity with 100 percent efficiency.

Atomic Switcheroo Explains Origins of Thin-Film Solar Cell Mystery

A research team from ORNL, the University of Toledo and DOE’s National Renewable Energy Laboratory used electron microscopy and computational simulations to explore the physical origins of treating cadmium-tellluride (CdTe) solar cell materials with cadmium-chloride to improve their efficiency.

Halving Hydrogen

First view of nature-inspired catalyst after ripping hydrogen apart provides insights for better, cheaper fuel cells.

Tracking Particles Faster at the LHC

A new trigger system will expand what ATLAS scientists can look for during high-energy collisions at the Large Hadron Collider.

Surprising Material Could Play Role in Saving Energy

Researchers at Northwestern University discover tin selenide is best at converting waste heat to electricity.

'Exotic' Material is Like a Switch When Super Thin

Researchers from Cornell and Brookhaven National Laboratory have shown how to switch a particular transition metal oxide, a lanthanum nickelate (LaNiO3), from a metal to an insulator by making the material less than a nanometer thick.

Jefferson Lab's CEBAF Accelerator Achieves 12 GeV Commissioning Milestone

Following an upgrade of the Continuous Electron Beam Accelerator Facility, the CEBAF accelerator delivered the highest-energy electron beams it has ever produced into a target in an experimental hall, recording the first data of the 12 GeV era.

Brookhaven and SLAC Scientists Capture Ultrafast Snapshots of Light-Driven Superconductivity

X-rays reveal how rapidly vanishing 'charge stripes' may be behind laser-induced high-temperature superconductivity.
