Hydrosilane-Free Access to Iridium-NNSi Catalysts via Activation of Unstrained Si–C Bonds for C(sp3)–H Borylation

Abstract Hydrosilane-free access to iridium–silyl species is achieved via cleavage of unstrained Si–C bonds within pyridyl-based ligand scaffolds. Treatment of (triorganosilyl)methyl-substituted 2,2′-bipyridine and 1,10-phenanthroline ligands with a tris(boryl)iridium complex ind...

Pore Structures and Acid–Base Properties of γ-Al2O3 Synthesized Using Different Precipitation and Drying Conditions

Abstract Although the alkali precipitation method is a significant industrial synthesis method for metal oxides, the effects of each process step on the physical and chemical properties of metal oxides have not been systematically investigated. This study performed a systematic i...

Interconvertible Helical Adsorption of Triptycene-Phenazine Molecules on Carbon Nanotubes Driven by Interfacial Interactions

Abstract Hybrid structures composed of triptycene–phenazine (Trip-Phz) molecules and carbon nanotubes have been experimentally reported to exhibit unique electrochemical properties; however, their molecular-level structures remain unclear. In this study, we investigate the adsorp...

Short‐Term Changes in General and Central Adiposity and Subsequent Cardiometabolic Risk in Japanese Adults Undergoing Routine Health Screening

ABSTRACT Objective Annual health screening provides repeated measurements of body mass index (BMI) and waist‐based indices, but the implications of short‐term changes in general and central adiposity for cardiometabolic risk remain unclear. We examined whether 1‐year changes in B...

Spin magnetic moments in the half-metallic ferromagnet—ferromagnet interface region detected by depth-resolved x-ray magnetic circular dichroism

We study spin magnetic moments near half-metallic Co2FexMn1−xSi (CFMS)/metal interfaces using depth-resolved x-ray magnetic circular dichroism (XMCD) and analyze their robustness against thermal fluctuations. We prepare epitaxial magnetic multilayered films with CFMS/CoFe and CFM...

Soft, Reactive, and Alive: A Dynamic Framework for Degradation and Functional Stability of Polymeric Biomaterials

Polymeric biomaterials do not degrade in vivo through isolated chemical or mechanical events. Hydrolysis, oxidation, enzymatic cleavage, fatigue, wear, protein adsorption, and lipid uptake often interact across the material surface, bulk, and surrounding biological environment, p...

The filtration performance of fabrics against particles of viral size: a systematic review

Wearing a mask is part of the comprehensive strategy to suppress transmission of the SARS-CoV-2 virus and respiratory tract infections. Despite available COVID-19 vaccines, wearing a mask has remained one of the simplest and most effective ways. There was, however, little data av...

Relative Effects of Fabry‐Perot, Mie, and Guided‐Mode Resonance in Periodic Photonic Lattice Physics

ABSTRACT We investigate the physical origins of resonance effects in one‐dimensional periodic photonic lattices (PhL), focusing on the relative roles of Fabry–Perot (FP), Mie, and guided‐mode resonance (GMR) mechanisms. Using rigorous numerical simulations and modal analysis, we...

Preparation and characterisation of dope‐dyed regenerated cellulose films using 1‐butyl‐3‐methylimidazolium chloride: A comparison of indigo and direct dyes

Abstract This study investigates the dissolution behaviour and dyeing performance of indigo and CI Direct Blue 1 in water, 1‐butyl‐3‐methylimidazolium chloride ([BMIM]Cl) and cellulose solutions and evaluates their effects on the properties of regenerated cellulose films (RCFs)....

Immediate changes in trunk extension and pain following a structured exercise program in high school baseball players with extension-type low back pain: a retrospective observational study

Abstract Background Extension-type low back pain (LBP) is common among baseball players, but immediate exercise responses may differ among athletes. Evidence on exercise-specific acute responses in adolescent athletes remains limited. This retrospective observational study examin...
