Spin-disorder-induced angular anisotropy in polarized magnetic neutron scattering

This paper experimentally demonstrates a previously unseen spin-disorder-induced angular anisotropy in the polarized small-angle neutron scattering cross section of magnetically inhomogeneous materials, providing a novel method for determining the exchange-stiffness constant based on micromagnetic theory.

Dehydration-Driven Ion Aggregation and the Onset of Gelation in ZnCl2_2 Solution

This paper presents a minimal model, validated by machine-learned molecular dynamics simulations, which demonstrates that dehydration drives ion aggregation in concentrated ZnCl2_2 solutions through two distinct transitions—forming Cl-bridged clusters at a coordination number of Z=2Z=2 and triggering gelation near Z≈3Z\approx 3—with cluster-size distributions matching percolation theory.

Topology-Directed Silicide Formation: An Explanation for the Growth of C49-TiSi2_2 on the Si(100) Surface

Through extensive DFT calculations, this paper proposes a topology-driven model explaining how the specific arrangement of Si(100) surface dimers and Ti adsorption patterns create a nucleation template that favors the formation of metastable C49-TiSi2_2 over the thermodynamically stable C54 phase, thereby rationalizing experimental growth behaviors and offering insights for optimizing metal-semiconductor junctions.

PowderLine: a programmatic powder diffraction analysis application

The paper introduces PowderLine, a Python application that streamlines high-throughput powder diffraction analysis by encapsulating Rietveld or single-peak refinement workflows into validated, machine-readable declarative recipes, thereby enabling seamless integration into interactive, scripted, and autonomous laboratory systems.

Over what length scale does an inorganic substrate perturb the structure of a glassy organic semiconductor?

This study reveals that inorganic substrates induce a disordered molecular packing in vapor-deposited DSA-Ph glassy organic semiconductors extending approximately 8 nm from the interface, beyond which the bulk structure is primarily governed by the deposition temperature.

Temperature-Induced Reorganization of Supported Zn3_3 Clusters on Cu(111): From Minimum-Energy Structures to Finite-Temperature Ensembles

This study demonstrates that finite-temperature entropic effects fundamentally alter the preferred structures of supported Zn3_3 clusters on Cu(111) from compact triangular shapes to extended linear configurations, challenging the reliability of identifying catalytic active sites based solely on static 0 K minimum-energy models.

Second Harmonic Generation Spectroscopy of the Surface Charge Density Wave in the Weyl Semimetal CoSi

Using temperature-dependent rotational anisotropy second harmonic generation, researchers identified a purely surface-driven charge density wave transition on CoSi (001) at 90 K that exhibits a critical exponent consistent with the 3D XY universality class, a result attributed to the coupling between surface Fermi-arc states and bulk topology.
