Copper‐Catalyzed Markovnikov Hydroboration of Alkenes via Hydrogen Atom Transfer (MHAT)
Advanced Synthesis &Catalysis, Volume 368, Issue 3, 3 February 2026.The copper‐catalyzed Markovnikov hydroboration of alkenes is disclosed. Remarkably, this methodology operates at mild reaction conditions and delivers high catalytic efficiency (TONs and TOFs up to 2800 and 2600 h‐1, respectively). Furthermore, this approach diverges from previous reports by relying on two subsequent hydrogen‐atom‐transfer processes ...

Aqueously Upcycled Lignin with Emergent Tribonegativity for Skin‐Integrated Triboelectronics
Advanced Materials, Volume 38, Issue 9, 12 February 2026.Aqueously upcycled lignin is transformed into a printable ink that self‐assembles into a nanotextured surface during printing with the highest reported biopolymer‐based tribonegativity. The resulting skin‐integrated triboelectric sensor enables high‐fidelity cardiovascular monitoring and objective mental workload classification, demonstrating a ...

Fluoreszenzlöschung von Stilben
CHIMIA, 1965 The quenching of the fluorescence of trans-stilbene in solution has been investigated. The quantum yield decreases strongly with increasing concentration of the solute (concentration quenching). On the other hand, the quenching effect of cis-stilbene and 1.1-diphenyl-ethylene is very small.

Aggregate, Volume 7, Issue 2, February 2026.A push–pull bridged stilbene (DpCBS[7]) demonstrates both solvatochromism and aggregation‐induced emission (AIE) within a compact molecular framework. Despite polarity‐dependent emission shifts, its fluorescence quantum yield remains low in solution due to ultrafast internal conversion.

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.ABSTRACT Ora‐pro‐nobis (OPN) is a food plant with polyphenol‐rich leaves. However, the influence of seasonality on their quantitative phenolic composition and how it impacts their bioactivities is unknown. OPN leaves were harvested throughout 12 months, and their individual phenolic content, antioxidant activity, and erythroprotection were assessed ...
