Scientific Achievement: Ion flux diagnostics combined with in-situ Raman spectroscopy revealed that damage to monolayer (ML) graphene during pulsed laser deposition (PLD) of a protective layer is primarily driven by fast ions, and that
Scientific Achievement: Method developed for solids matches accuracy of quantum chemistry approaches with a 1000 times smaller basis allowing calculations of larger systems.
Researchers with the Department of Energy’s Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have created an innovative method to visualize and analyze atomic structures within specially designed, ultrathin bilayer 2D materials.
Scientific Achievement: Neutron and X-ray scattering show that bulk RuO₂ exhibits a highly correlated ground state without magnetic moments, despite prior claims of altermagnetism.
Scientific Achievement: Atomic-scale simulations and experiments revealed the acidity of MgO surface sites and suggested their hydroxylation as the mechanism for Mg(OH)2 conversion.
Scientific Achievement: Using novel non-invasive characterization, demonstrated that dynamic bonding in fiber-polymer interface controls the topological freezing transition and induces shape reforming of the glassy material.
Scientific Achievement: Cantilever-based measurement demonstrated that collective chiral atomic vibrations, known as chiral phonons, possess and transport angular momentum, connecting quantum properties to mechanical responses.
Scientific Achievement: By resolving the atomic structure of individual layers in twisted bilayers, this work provides unprecedented access to dopant and defect distributions that were previously inaccessible due to moiré-induced obscur
Scientific Achievement: Calculations predict, contrary to common belief, that magnon mode softening and decoherence of magnetic excitations can arise in purely electronic quantum models without phonons.
Scientific Achievement: AlCl3-containing molten salts were found to ensure high catalytic efficiency in the conversion of polyethylene plastics to fuels through the stabilization of carbenium interm
