Enhanced Optical Efficiency of 3D‐Printed Single‐Dye LSCs Under Photosynthetically Active Radiation (PAR) Illumination

Solar RRL, Volume 9, Issue 24, December 2025.
3D‐printed luminescent solar concentrators (LSCs) doped with Perylene Red and Orange dyes are fabricated via stereolithography and evaluated under photosynthetically active radiation. Optically coupled configurations achieve optical efficiencies up to 31% and power conversion efficiencies of 3.6%.

Dual Clumped Isotope (Δ47, Δ48) Values for Calcite Grown at Varying pH and Carbonic Anhydrase Concentrations Constrain Equilibrium and Kinetic Isotope Effects

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract This study explores the isotopologues m/z 47 (13C18O16O, denoted Δ47) and m/z 48 (12C18O2, denoted Δ48) in CO2 derived from carbonate minerals, focusing on their temperature dependency, kinetic isotope effects, and distinct reaction pathways. By conducting experiments at four temperatures (5°C, 10°C, 15°C, and 25°C) using the enzyme carbonic ...

The Influence of Space Weathering on the Far‐Ultraviolet Reflectance of Apollo‐Era Soils

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Building on our previous studies of the far‐ultraviolet (FUV) reflectance of Apollo soil 10084 and lunar soil simulants JSC‐1A and LMS‐1 (Gimar et al., 2022, https://doi.org/10.1029/2022je007508; Raut et al., 2018, https://doi.org/10.1029/2018je005567), we present new FUV results for Apollo soils 68501 and 71061. Heavily weathered soils (68501,

Physics‐informed machine learning analysis for nanoscale grain mapping by synchrotron Laue microdiffraction

Journal of Applied Crystallography, Volume 58, Issue 6, Page 1880-1886, December 2025.
Our work presents a physics‐informed machine learning approach that advances materials characterization by overcoming the fundamental resolution limits of synchrotron X‐ray Laue microdiffraction. By integrating deep learning with physical constraints, we demonstrate that nanoscale grain mapping can be achieved even when using micrometre‐sized X‐ray ...

The Body in Extremist White Supremacism

The British Journal of Sociology, Volume 76, Issue 5, Page 975-986, December 2025.
ABSTRACT This article advances the study of racial extremism by analyzing how its practices of violence and sexuality are marked on the bodies of participants in the form of scars, physical stances, abuse, tattoos, pregnancy, injury, strength and size, using an extraordinarily rich and extensive set of narratives collected from lengthy in‐person ...
