New iCOF material selectively sequesters Cr(VI) oxoanions in the presence of other anions, such as sulfate and nitrate.
The clusters are assembled through steric and electrostatic forces, with the chloride anions (green spheres) residing in equidistant ‘clefts’ between coordinating diglycolamide ligands in positions that satisfy both repulsive and attractive ion-ion
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
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
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
This work shows that nonclassical multiphoton interferences can be achieved at the subwavelength scale in all-dielectric metasurfaces.
A unique combination of imaging tools and atomic-level simulations allowed the team to solve a longstanding debate about the properties of a promising material that can harvest energy from light.
Understanding the 3-D distribution and nature of active sites in heterogeneous catalysts is critical to developing useful structure−function relationships but it is very difficult to achieve such 3-D information.
A general approach for quantitatively investigating the spatiotemporal dependence of structural relaxation in deformed polymers based on using small-angle neutron scattering alongside HPC-enabled nonequilibrium molecular dynamics simulations was develop
