Nickel-Catalyzed β-Methyl Vinylation Using Allylamine as a Masked Alkenyl Electrophile

Abstract Direct activation of native C(sp2)–NH2 bonds in alkenyl amines remains a largely unmet challenge in cross-coupling chemistry owing to their high bond dissociation energies, poor leaving-group ability, and competing tautomerization pathways. Herein, we report a nickel-cat...

Artificial Intelligence-Assisted FT-IR Spectral Sensing: From Molecular Fingerprints to Quantitative and Interpretable Chemical Information

Fourier-transform infrared (FT-IR) spectroscopy provides rapid, accessible, and chemically informative molecular fingerprints, but quantitative analysis of complex samples is often hindered by band overlap, baseline variation, matrix effects, and nonlinear relationships between s...

Shape-Controlled Poly(N-isopropylacrylamide) Actuators Enabled by Tensile-Stress Mismatch for Temperature-Adaptive Textiles

Thermal comfort is a key determinant of human health and requires adaptive responses to dynamic environments. Here, we report a temperature-adaptive textile enabled by a tensile stress mismatch-driven poly(N-isopropylacrylamide) (PNIPAM) actuator operating within a human-friendly...

Elucidating the Process–Structure–Property Relationships in Spray-Dried K3V2(PO4)3/C Microspheres for High-Performance Potassium-Ion Batteries

Polyanion-based K3V2(PO4)3 (KVP) has emerged as a promising cathode material for potassium-ion batteries (KIBs); however, its practical application is severely hindered by intrinsically low electronic conductivity and structural degradation during cycling. Although spray-drying (...

Symptom-Based Hospitalization Risk Differs Between Ulcerative Colitis and Crohn’s Disease: A Nationwide Emergency Department Study

Presenting symptoms guide emergency department (ED) triage and admission decisions in inflammatory bowel disease (IBD), but whether symptoms have similar predictive value in ulcerative colitis (UC) and Crohn’s disease (CD) remains unclear. We examined disease-specific association...

Framing hotel strategies for demand uncertainty: The asymmetric effects of cancellation policies and F&B incentives

This study examines how hotels manage demand uncertainty through two contrasting strategies: cancellation policies as loss-framed uncertainty reduction tools and food and beverage incentives as gain-framed coping mechanisms. Drawing on prospect theory, we argue that these approac...

Comparison of stool DNA–based SDC2 methylation testing and repeat fit for advanced colorectal neoplasia in fit-positive individuals: a multicenter prospective exploratory study
