Photolithographically defined thin film Au dots were used as micro fiducial markers for digital image correlation (DIC), to enable two-dimensional strain measurement of 200 micron-thick LIGA (Lithographie, Galvanformung, Abformung) nickel alloys. Due to
Spin structure of a magnetic system results from the competition of various exchange couplings. Pressure driven spin structure evolution, through altering interatomic distance and hence electronic structure, produces baromagnetic effect(BME), which has

The International Materials Resource Registries (IMRR) working group of the Research Data Alliance (RDA) was created to spur initial development of a federated registry system to allow for easier discovery and access to materials data. As part of this

New linkages for covalent organic frameworks (COFs) have been continuously pursued by chemists as it serves as the structure and property foundation for the materials. Developing new reaction types or modifying known linkages have been the only two methods

The widespread implementation of H 2 as a fuel is currently hindered by the high pressures or cryogenic temperatures required to achieve reasonable storage densities. In contrast, the realization of materials that strongly and reversibly adsorb hydrogen at

For the number of skutterudite-related cage compounds such as cubic R 3M 4Sn 13 (R = Ca or La, M = transition d-electron metal) or tetragonal Y 5Rh 6Sn 18 we have previously reported the impact of various atomic defects in the crystal lattices on the

Reversible aggregation of purely short-ranged attractive colloidal particles leads to the formation of clusters with a fractal dimension that only depends on the second virial coefficient. The addition of a long-ranged repulsion to the potential modifies

The surface capping ligands on nanocrystals (NCs) impart colloidal stability and determine the organization into ordered solids when cast from solution. Here, we use small-angle neutron scattering (SANS) to measure the solution structure factor in

We study the assembly of magnetite nanoparticles in water-based ferrofluids in wetting layers close to silicon substrates with different functionalization without and with an out-of-plane magnetic field. For particles of nominal sizes 5 nm, 15 nm and 25 nm
This study demonstrates how the large concentration fluctuations of polymeric liquids under deformation and flow can be quantitatively studied by applying the spherical harmonic expansion technique to small-angle neutron scattering. Using a series of

This work probes the slurry architecture of a high silicon content electrode slurry with and without low molecular weight polymeric dispersants as a function of shear rate to mimic electrode casting conditions for poly(acrylic acid) (PAA) and lithium

Thin films of two types of high-entropy oxides (HEOs) have been deposited on 76.2 mm Si wafers using combinatorial sputter deposition. In one type of the oxides, (MgZnMnCoNi)Ox, all the metals have a stable divalent oxidation state and similar cationic

The microscopic origin of mechanical enhancement in polymer nanocomposites (PNCs) is investigated through the combination of rheology and small-angle neutron scattering. It is shown that in the absence of an extensive particle network, the molecular

Electron core-hole processes at absorption edges sport several signatures, primarily in the form of bound states and/or excitonic enhancement. Through analysis of the resonant-Raman Auger effect for the 2-dimensional transition-metal dichalcogenide MoS2
This chapter presents a high-level description of a suite of programs denoted by the acronym OCEAN (Obtaining Core Excitation spectra ab initio and with NBSE), where NBSE denotes the underlying NIST Bethe-Salpeter Equation program. The main computational

Critical Casimir force (CCF) is a solvent fluctuation introduced interaction between particles dispersed in a binary sol-vent. Recently, it has been demonstrated that the CCF induced attraction between particles can cause the particle size-sensitive
