Angewandte Chemie International Edition, EarlyView.Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Archaeological Prospection, EarlyView.ABSTRACT The Coëby Neolithic cemetery, located in the commune of Trédion (Morbihan, France) and discovered in 1986, has been for several years the subject of a research programme focused on studying the various megalithic structures present. The spatial distribution of these remains highlights an unusual occupation of the territory, organized according

Anatomical Sciences Education, EarlyView.Abstract Providing students with a way to honor human body donors during or after an anatomy course has been shown to help provide a sense of closure and comfort to students and, when present, donor families. Gestures of gratitude for donors can also emphasize humanistic values of respect, empathy, and professionalism.

Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...
