For the first time, researchers have synthesized lateral semiconductor heterojunctions in lithographically patterned arrays within a two-dimensional semiconductor crystal monolayer by a novel process that selectively converted exposed regions
Theoretical calculations, based on newly obtained experimental geometries in strained BiFeO3 thin films, predict an almost barrierless transition between co-existing phases.
An effective approach to sulfate separation from aqueous solutions was developed based on crystallization of sulfate-water clusters with a simple ligand self-assembled in situ from water-soluble subcomponents.
A novel simulation of metallic glasses demonstrates that atomic relaxation modes during deformation depend on the density of local minima in the systems’ underlying potential energy landscape (PEL).
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.
Organometal halide perovskite-based solar cells represent a major breakthrough in emerging photovoltaic technology as the reported power conversion efficiency has extended beyond 20%.
We discovered dislocations in the electrical double layer (EDL) in a room-temperature ionic liquid (RTIL) by direct 3D atomic force microscopy (AFM) imaging with molecular resolution.
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.
A multimodal imaging platform was developed that, for the first time, provides co-registered topographic, nanomechanical, and chemical imaging information (via mass spectrometry) of a surface with submicron pixel size.
A hypercrosslinked polymer was synthesized by a Friedel-Crafts alkylation of a phenolic resin with a robust mesoporous framework to avoid framework shrinkage and maximize retention of organic functional groups.
ORNL researchers successfully developed a so
