Reconstruction of 3D Conductive Networks in Metal‐Filled Elastomer Composites Indicates Dominance of Contact Resistances

Small Structures, EarlyView.
Advanced image analysis uses 3D‐reconstructed filler particle networks in silver polydimethylsiloxane conductive polymer composites to decouple network structure and particle–particle contact resistance above the percolation threshold. The silver loading‐dependent changes in network structure are not large enough to explain the change in macroscopic ...

Investigations on Structural, Stability, and Magnetic Properties of Zr4Mn4Si7

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
This study reports experimental and theoretical investigations on Zr4Mn4Si7, revealing a novel crystal structure (space group P4/nmm) related to the Zr4Co4Ge7‐type. Density Functional Theory calculations, supported by experiments, indicate that silicon deficiency and temperature critically influence phase stability.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Chronic silencing of subsets of cortical layer 5 pyramidal neurons has a long‐term influence on the laminar distribution of parvalbumin interneurons and the perineuronal nets

Journal of Anatomy, Volume 246, Issue 4, Page 479-504, April 2025.
Chronic silencing of subsets of layer 5 projection neurons has distinct effects on the laminar distribution of PV interneurons and the perineuronal nets in the adult primary motor and somatosensory cortex. Abstract Neural networks are established throughout cortical development, which require the right ratios of glutamatergic and GABAergic neurons ...

Heavy‐duty conceptual engineering

Noûs, EarlyView.
Abstract Conceptual engineering is the process of assessing and improving our conceptual repertoire. Some authors have claimed that introducing or revising concepts through conceptual engineering can go as far as expanding the realm of thinkable thoughts and thus enable us to form beliefs, hypotheses, wishes, or desires that we are currently unable to ...

Mining an Anthropocene in Japan: On the making and work of geological imaginaries

Transactions of the Institute of British Geographers, EarlyView.
Short Abstract This article addresses how the lithic and the drift might be reworked as an Anthropocene material outside of a chronostratigraphy. Revisiting the finding of a floating fern fossil at the Hashima mine, we delve into a complex array of Geological imaginaries, and undertake our own speculative work.

Structural and Spectroscopic Trends in Alkali Tris(Acetato)Actinyl(VI) Complexes

European Journal of Inorganic Chemistry, Volume 28, Issue 19, July 12, 2025.
Alkali tris(acetato) actinyl(VI) complexes of different actinyls and identical alkali metals are mostly isostructural, showing a redshift in the symmetric actinyl stretch across the actinide series. With increasing alkali ionic radii, a progression to lower symmetry is observed that correlates with subtle changes in the electronic and vibrational ...

Structural and Optical Modification of Siloxene Nanosheets Driven by Selenium Doping

Chemistry – A European Journal, Volume 31, Issue 39, July 11, 2025.
Siloxene nanosheets are produced by topotactic deintercalation of a purified CaSi₂ phase and subsequently doped with selenium through thermal evaporation. Structural and spectroscopic analyses confirm dopant integration while preserving the 2D framework.
