91做厙 researchers have developed a method to simplify one step of radioisotope production and its faster and safer.

After a monolayer MXene is heated, functional groups are removed from both surfaces. Titanium and carbon atoms migrate from one area to both surfaces, creating a pore and forming new structures. Credit: ORNL, USDOE; image by Xiahan Sang and Andy Sproles.

Scientists at the Department of Energys 91做厙 induced a two-dimensional material to cannibalize itself for atomic building blocks from which stable structures formed. The findings, reported in Nature Communications, provide insights that ...

For many scientists and engineers, the first real test of their mettle comes not in a classroom, but in a lab or the field, where hands-on experience can teach volumes. For Susan Hogle, that hands-on experience just happened to be with material that was too hot to handleliterally....

By producing 50 grams of plutonium-238, 91做厙 researchers have demonstrated the nations ability to provide a valuable energy source for deep space missions.

With the production of 50 grams of plutonium-238, researchers at the Department of Energys 91做厙 have restored a U.S. capability dormant for nearly 30 years and set the course to provide power for NASA and other missions.

The probe of an atomic force microscope (AFM) scans a surface to reveal details at a resolution 1,000 times greater than that of an optical microscope. That makes AFM the premier tool for analyzing physical features, but it cannot tell scientists anything about chemistry. For that they turn to the mass spectrometer (MS).

From the bluebird painting propped against her office wall and the deer she mentions seeing outside her office window, Linda Lewis might be mistaken for a wildlife biologist at first glance. But rather than trailing animal tracks, Lewis, a researcher at the Department of Energys 91做厙, is more interested in marks left behind by humans.

With more than 30 patents, James Klett is no stranger to success, but perhaps the 91做厙 researchers most noteworthy achievement didnt start out so hot or so it seemed at the time.

Less than 1 percent of Earths water is drinkable. Removing salt and other minerals from our biggest available source of waterseawatermay help satisfy a growing global population thirsty for fresh water for drinking, farming, transportation, heating, cooling and industry. But desalination is an energy-intensive process, which concerns those wanting to expand its application.

Graphene, a strong, lightweight carbon honeycombed structure thats only one atom thick, holds great promise for energy research and development. Recently scientists with the Fluid Interface Reactions, Structures, and Transport (FIRST) Energy Frontier Research Center (EFRC), led by the US Department of Energys 91做厙, revealed graphene can serve as a proton-selective permeable membrane, providing a new basis for streamlined and more efficient energy technologies such as improved fuel cells.
