Recent Advances in Ene Reactions with Carbon Enophiles

Advanced Synthesis &Catalysis, EarlyView.
Recent advances in the classical intra‐ and intermolecular ene nexus with carbon enophiles (alkenes, alkynes, arynes, and allenes) show a considerable increase in structural complexity and an enormous potential for functional applications in polymer science.

Electrochemical Trifluoromethylchlorosulfonylation of Alkenes via Copper‐Mediated SO2Cl Radical Transfer

Advanced Synthesis &Catalysis, EarlyView.
This article reports an electrosynthetic method for vicinal trifluoromethylchlorosulfonylation of alkenes using [Cu(MeCN)4]PF6 and triethylamine, without elaborate ligands. The reaction efficiently adds CF3 and SO2Cl across diverse unactivated alkenes with broad functional group tolerance.

Highly Sensitive Detection of Human Serum Albumin Biomarker Using a Molecularly Imprinted Polymer‐Based Electrochemical Capacitance Sensor

Advanced Sensor Research, EarlyView.
An electrosynthesized protein‐imprinted polymer (poly(azo‐BBY)) enables probe‐free, real‐capacitance detection of human serum albumin at 0.02 ng mL−1 within a 0.25–3.0 ng mL−1 window. The device uses a redox‐mediator‐free architecture and maintains selectivity against common interferents, illustrating a simple, scalable route to high‐sensitivity ...

Ni Single Atoms in Zeolite Beta for Selective Alkyne Hydrogenation

Advanced Sustainable Systems, EarlyView.
Single‐atom Ni in zeolite Beta (Ni1/BEA) selectively remove trace acetylene from ethylene. Ni1/BEA achieve full conversion with ≈89% ethylene selectivity, stable for 24 h without coking, and 12 times higher TOF than prior zeolite‐supported single‐atom Ni catalysts. Na+ exchange suppress Brønsted acid‐catalyzed oligomerization. Under ethylene‐rich feeds,

Hemp Proteins Conjugated with Green Tea Polyphenol Extract Form De Novo Plant‐Sourced Emulsifiers Suitable for Nanodelivery Systems Bearing Lipophilic Psychopharmaceuticals

Advanced Therapeutics, EarlyView.
Green tea polyphenols, conjugated either covalently or non‐covalently to hemp protein, comprise an excellent stabilizing matrix for oxidatively‐sensitive small molecules. These nanoemulsions are highly stable to a variety of chemical and physical stressors, protecting the small molecule while allowing for easy uptake across cell membranes and rapid ...
