A unique catalyst paves the way for plastic upcycling
31-May-2022
A recently developed catalyst for breaking down plastics continues to advance plastic upcycling processes. In 2020, a team of researchers led by Ames Laboratory scientists developed the first processive inorganic catalyst to deconstruct polyolefin plastics into molecules that can be used to ...
Surprising semiconductor properties revealed with innovative new method
Discovery reveals role of oxygen impurities in semiconductor properties
11-Mar-2022
A research team probing the properties of a semiconductor combined with a novel thin oxide film have observed a surprising new source of conductivity from oxygen atoms trapped inside. Scott Chambers, a materials scientist at the Department of Energy’s Pacific Northwest National Laboratory, ...
New electrolyte for solid-state lithium-ion batteries
New battery material offers promise for the development of all-solid batteries
18-Feb-2022
In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flammable. As a result, solid-state lithium-ion batteries, which consist of entirely ...
A “fairly simple” breakthrough makes accessing stored hydrogen more efficient
New catalyst extracts hydrogen from hydrogen storage materials easily and efficiently
15-Feb-2022
A new catalyst from the U.S. Department of Energy’s Ames Laboratory and collaborators extracts hydrogen from hydrogen storage materials easily and efficiently. The process occurs at mild temperatures and under normal atmospheric conditions, without using metals or additives. The breakthrough ...
Inside the battery in 3D
Powerful X-rays watch solid state batteries charging and discharging
08-Feb-2021
Despite worldwide use of lithium batteries, the exact dynamics of their operation has remained elusive. X-rays have proven to be a powerful tool for peering inside of these batteries to see the changes that occur in real time. Using the ultrabright X-rays of the Advanced Photon Source (APS), a ...
How do you know it's perfect graphene?
The answer has been there all along
04-Nov-2019
Producing structurally perfect graphene and other 2D materials is the secret to tapping into their potential novel electronic and spintronic properties. But how do we know when graphene, the most widely studied 2D material, is perfect-- a defect-free and uniform layer of atoms? Scientists at the ...
Scientists pioneer new low-temperature chemical conversion process
05-Apr-2019
Chemists spend a great deal of time and energy trying to get chemical reactions to begin or to speed up -- but sometimes it can be just as important to stop them before they go too far. In a recent study from the U.S. Department of Energy's (DOE) Argonne National Laboratory, chemists have ...
Physicists uncover new competing state of matter in superconducting material
04-Jan-2019
A team of experimentalists at the U.S. Department of Energy's Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that ...
A most singular nano-imaging technique
Berkeley Lab's SINGLE provides images of individual nanoparticles in solution
20-Jul-2015
Just as proteins are one of the basic building blocks of biology, nanoparticles can serve as the basic building blocks for next generation materials. In keeping with this parallel between biology and nanotechnology, a proven technique for determining the three dimensional structures of individual ...
X-rays and electrons join forces to map catalytic reactions in real-time
01-Jul-2015
A new technique pioneered at the U.S. Department of Energy's Brookhaven National Laboratory reveals atomic-scale changes during catalytic reactions in real time and under real operating conditions. A team of scientists used a newly developed reaction chamber to combine x-ray absorption ...
