Research Highlights
By studying the inner workings of lithium-ion batteries, Oak Ridge National Laboratory researchers have developed a highly sensitive technique to characterize and measure at the electrolyte and electrode interface.
Researchers discovered that a hidden ferromagnetic insulating (FMI) state emerged in Sr2Fe1+xRe1-xO6 films when the material’s local ionic order was disturbed by a small modification in cation ratio.1 This work provides a promising new route to developing
This research overcomes limitations in poor solubility of heterometallic double complex salt (DCS) precursors by using a clever sequential adsorption of metal cations and anions onto a silica support followed by an efficient reduction step which convert
This work directly measured the intrinsic surface conductance of topological insulators by using a four-probe scanning tunneling microscope (4-Probe STM) to tune the crossover of bulk-to-surface conductance. A scattering-free spin transport was reveale
This work successfully demonstrated size and geometry customizable carbon microelectrode sensors using templates produced with the CNMS Nanoscribe. These novel carbon electrodes were then implanted into a rat brain to detect dopamine release in vivo.
Researchers utilized a roll-to-roll process to coat electrically conductive carbon fibers with semiconducting silicon carbide nanoparticles—demonstrating a scalable method to make reinforcing fibers for composite applications requiring strong, lightweig
CNMS electron microscopy and quantitative EELS, combined with quantum chemistry calculations (Los Alamos Institutional Computing Program) identifies FeN4 clusters ligated with OH as the predominant active sites in a platinum group metal (PGM)-free catal
This work presents a direct observation of electric field induced motion/response of ionic diblockcopolymer thin films with nanoscale resolution using In situ neutron reflectometry measurements and molecular dynamics simulations.
This joint CNMS-CFN research effort built on unique capabilities of two NSRCs and resulted in a new hybrid nanocomposite sensor material with ~20 times higher gravimetric response than pure polymer thin films, and that could be further enhanced by addit
