Compositional complexity is found to strongly affect electrical, thermal, and magnetic properties of nickel-containing face-centered cubic concentrated alloys.
Compared to pure nickel, tuning chemical composition in binary alloys has altered migration barriers of defects, and significantly affected defect dynamics under ion irradiation.
Researchers demonstrated that straining the crystal lattice of strontium cobaltite reduces oxygen content even under highly oxidizing conditions, enabling formation of functional oxygen defects at lower temperatures than previously possible.
Multiferroic materials are important because their electrical and magnetic properties are coupled. Because BiFeO3 magnetically orders below 640 K, it is one of two known room-temperature multiferroic materials.
Researchers discovered that isolated platinum atoms in copper surfaces efficiently catalyze the selective hydrogenation of 1,3 butadiene, a reaction important for many industrial applications.1 A new generation of catalysts with one Pt atom for approximate
While palladium, a common catalyst, oxidizes easily, it has now been shown that palladium films grown on ruthenium are surprisingly inert to oxidation when they are thinner than six atomic layers.
The ability to control the binding strength of molecules t
Theoretical calculations, based on newly obtained experimental geometries in strained BiFeO3 thin films, predict an almost barrierless transition between co-existing phases.
To test a key instrument of a spacecraft that will fly closer to the sun than any before, engineers at Oak Ridge National Laboratory and the University of California–Berkeley used ORNL’s powerful plasma-arc lamp as a solar heat flux simulator.
Researchers have developed a process1 to make thermosets—plastics once stuck in their final forms due to cross-linking of chemical bonds—that can now be reshaped and reused.
