Radical Cascade Combining Cross‐Olefin Coupling with the Smiles‐Truce Rearrangement

open access: yesAngewandte Chemie International Edition, EarlyView.
We present a cobalt‐catalysed radical cascade that efficiently merges two alkene starting materials to form multiple bonds in a single step. The process begins with a cobalt‐catalysed hydrogen‐atom transfer‐to a styrene double bond, followed by a Giese addition.

Beighton Scoring System Use in Generalized Joint Hypermobility Studies Has Greater Scientific Rigor Than Joint‐Specific or Arthroscopy Joint Hypermobility Studies

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To compare the scientific rigor of Beighton Scoring System (BSS) use in generalized joint hypermobility (JH) studies (healthy subject injury risk/rate, physiological or kinesiological function determination) and joint‐specific or arthroscopy JH studies; to identify the most commonly used BSS score thresholds; and to describe ways to improve BSS

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

open access: yesArthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Metal Nanoparticles on Halloysite Applied in Stereoselective Hydrogenation of Tetrasubstituted Alkenes

open access: yesChemistry – A European Journal, EarlyView.
Composite materials based on metal nanoparticles supported on a naturally occurring nanotubular clay, halloysite (HAL), led to the diastereoselective hydrogenation of tetra‐substituted alkenes under relatively smooth conditions, mainly oxazolidinone‐based heterocycles.

Semiconducting Single‐Wall Antimony Oxide Nanotubes and Oxidotritelluridoantimonate(V) Anions

open access: yesChemistry – A European Journal, EarlyView.
Antimony(V) binds directly to tellurium(−II) in the (SbOTe3)3− anion. The latter has been found between Sb2O3 nanotubes in a microporous cetineite structure. The Sb2O3 nanotube is positively polarized on its outer surface and negatively polarized on its inner surface, corresponding to a cylindrical capacitor. Substantial charge transfer from the anions

Bridging Theory and Prediction: A Hybrid SEM and Machine Learning Approach to Optimize Lean Construction for Megaproject Sustainability in China

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Construction megaprojects, large‐scale, complex, and capital‐intensive, are particularly prone to inefficiencies, cost overruns, delays, and environmental degradation due to fragmented workflows, stakeholder misalignment, and resource intensity.
