Researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated that permanent magnets produced by additive manufacturing can outperform bonded magnets made using traditional techniques while conserving critical materials. The project is part of DOE’s Critical Materials Institute (CMI), which seeks ways to eliminate and reduce reliance on rare earth metals and other materials critical to the success of clean energy technologies.
Automated metrology system for Pu 238
Under a collaborative partnership between the NASA and DOE, a new automated measurement system developed ORNL will ensure quality production of plutonium-238 while reducing handling by workers. NASA has funded ORNL and other national laboratories to develop a process that will restore US pr ... more
Nano-spike catalysts convert carbon dioxide directly into ethanol
In a new twist to waste-to-fuel technology, scientists at the Department of Energy’s Oak Ridge National Laboratory have developed an electrochemical process that uses tiny spikes of carbon and copper to turn carbon dioxide, a greenhouse gas, into ethanol. Their finding, which involves nanof ... more
Tennessine announced as provisional name for superheavy element 117
The International Union of Pure and Applied Chemistry (IUPAC) Inorganic Chemistry Division has published a Provisional Recommendation for the names and symbols of the recently discovered superheavy elements 113, 115, 117, and 118. Tennessine (Ts) is proposed for element 117, recognizing the ... more
Polymer discovery gives 3D-printed sand super strength
Researchers at the Department of Energy’s Oak Ridge National Laboratory designed a novel polymer to bind and strengthen silica sand for binder jet additive manufacturing, a 3D-printing method used by industries for prototyping and part production. The printable polymer enables sand structur ... more
Modeling uncovers an "atomic waltz" for atom manipulation
Researchers at the University of Vienna’s Faculty of Physics in collaboration with colleagues from the Oak Ridge National Laboratory in the USA have uncovered a non-destructive mechanism to manipulate donor impurities within silicon using focused electron irradiation. In this novel indirect ... more
Tiny but mighty precipitates toughen a structural alloy
Scientists at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have found a way to simultaneously increase the strength and ductility of an alloy by introducing tiny precipitates into its matrix and tuning their size and spacing. The preci ... more
