Structural Profiling of Lipid Nanoparticles at Sub‐10 nm Resolution via AF4 Coupled Online to SAXS and SANS

Small Methods, EarlyView.
Dilution‐controlled AF4 coupled with SAXS and, for the first time, SANS enables high‐resolution characterization of non‐spherical lipid nanoparticles. Enhanced scattering contrast and D2O‐based measurements resolve particle features down to ∼5 nm and reveal shape distributions.

Low‐Dose Electron Total Scattering Analysis Resolves Non‐Crystalline Phase Separation in Polymer Semiconductors and Device Multilayers

Small Methods, EarlyView.
The performance of polymer blend semiconductors is governed by both the degree of phase separation and crystallization, but these two aspects have remained unresolved. We report methods for mapping amorphous‐amorphous as well as amorphous‐crystalline phase separation in polyfluorene‐based polymer blends using spatially resolved nanobeam electron total ...

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Crystal Structures and Magnetic Properties of Coordination Polymer Complexes of Metal Ions With Kojic Acid Ligands

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
One‐dimensional coordination polymers of Cu(II) and Co(II) with kojic acid show distinct chain connectivities revealed by X ray crystallography and exhibit extremely weak magnetic interactions, as supported by magnetic measurements and molecular orbital calculations. The crystal structures and magnetic properties of coordination complexes [Cu(C6H5O4)2]

Approximate resolution convolution function for fitting a dispersion gap measured on a triple‐axis spectrometer

Journal of Applied Crystallography, EarlyView.
An analytical convoluted gap function is presented for fitting either a linear or a quadratic dispersion gap in a constant‐Q cut measured with a focused triple‐axis spectrometer. It outperforms previous methods of fitting a gap, without requiring a full resolution convolution.We present an analytical convoluted gap function for fitting dispersion gaps ...

Magnetic structure in the two‐dimensional van der Waals ferromagnet Fe3GaTe2

Journal of Applied Crystallography, EarlyView.
High‐quality single crystals of Fe3GaTe2 were grown using the chemical vapour transport method, allowing for a precise determination of their crystal and magnetic structures. A shortening of the Fei–Fei distance enhances the Fe–Fe exchange interaction, providing a microscopic origin for its higher Curie temperature compared with Fe3GeTe2.High‐quality ...
