Scientists found that the collective nanoparticle dynamics in polymer nanocomposites could be up to three orders of magnitude slower than the self-diffusion limit of isolated nanoparticles.
Researchers showed that dual-function intermetallic nanoprecipitates simultaneously enhanced strength and ductility of medium-entropy alloys via synergistic spatial confinement effects on two distinct deformation mechanisms: precipitation
Scientists at ORNL 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.
Fractional-excitation-phonon coupling in α-RuCl3 is observed, validating phonons as a sensitive probe of hidden fractional and non-local excitations, experimentally confirming the theoretically predicted coupling and providing the key information
The mechanisms of van der Waals (vdW) epitaxial growth of monolayer two-dimensional (2D) crystals from amorphous precursors were revealed by in situ pulsed laser heating within a TEM and first-principles calculations.
Researchers discovered that Li infiltration in solid oxide electrolytes for all-solid-state batteries is associated with local electronic structure at grain boundaries (GBs) rather than exclusively at Li-electrolyte interfaces as in Li-ion batt
Scientists demonstrated switching between topological and magnetic ground states by controlling the concentration of magnetic defects in a crystal.
Demonstrated that structural order parameters and local concentration-driven phase transitions can be described on atomic level from scanning transmission electron microscopy (STEM) data.
Precision synthesis approach discovered that epitaxial strain can deliberately position transition metals at a certain crystallographic position in a composite ferroelectric.
Researchers decrypted the formation of passivation layers for the promising bis-(fluorosulfonyl)-imide (FSI-) based ionic liquid electrolyte on carbon electrodes at high cell voltages.
