A laser heating diamond anvil cell system for high-pressure nuclear resonant scattering at 3-ID, APS

Cijin Zhou, Barbara Lavina, T. S. Toellner, Vitali B. Prakapenka et autres

Nuclear resonant scattering (NRS) provides the basis for powerful synchrotron-based techniques, including synchrotron Mössbauer spectroscopy (SMS) and nuclear resonant inelastic x-ray scattering (NRIXS), which probe the elastic, magnetic, thermodynamic, and vibrational properties of iron-bearing materials and are, therefore, well suited for studying …

Crossover dynamics of non-Fickian ionic diffusion in solids

Gangbin Yan, Pierfrancesco Ombrini, Zhichu Tang, Shakul Pathak et autres

Ionic diffusion in solids underpins energy storage, electronics, and catalysis, yet conventional diffusion models often fail to capture complexities arising from confinement, crystallographic disorder, lattice distortions, and coupled transport with phonons or electrons. These challenges are particularly pronounced in battery materials, where …

Preaccretionary origin of clay minerals in CI chondritic objects? Insights from the Orgueil clay mineralogy and iron oxidation state

J.-C. Viennet, Kana Amano, Ludovic Delbes, Barbara Lavina et autres

Phyllosilicates are the main phases in carbonaceous Ivuna-type (CI) materials and major carriers of water (structural OH) as well as of some organic matter adsorbed on their surfaces. Understanding their formation is therefore crucial for reconstructing the history of water and carbon …

Spin Glass Behavior and Giant Magnetoresistance via Aliovalent Fe/Ni Alloying in Amorphous Tetrathiafulvalene-Tetrathiolate Coordination Polymers

Chen‐Yu Lien, Jiehao Chen, Anna O. Schouten, G. Wilkinson et autres

The discovery of materials with programmable combinations of charge transport and magnetic properties is a major goal in synthetic chemistry. Molecular materials, such as coordination polymers (CPs), are emerging candidates in this field due to their synthetic modularity. While there are many …
