Liposomal Delivery of L‐2‐Hydroxyglutarate for Targeting Epigenetic Dysregulation in Osteoarthritis

open access: yesAdvanced NanoBiomed Research, EarlyView.
Osteoarthritis involves cartilage degeneration, inflammation, and epigenetic dysregulation. A liposomal formulation of the TET1 inhibitor L‐2‐hydroxyglutarate to overcome rapid joint clearance was developed. The formulation showed good physicochemical properties, reduced inflammatory and catabolic gene expression in chondrocytes, and alleviated ...

Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva

open access: yesAdvanced NanoBiomed Research, EarlyView.
A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...

Palladacarboxamide Capping Reagents for Carbon Isotope Labeling and Pharmaceutical Diversification

open access: yesAngewandte Chemie, EarlyView.
Herein, we present a method for carbon isotope labeling of arylamides via the coupling of air‐stable palladium carboxamide complexes and boronic ester/acids. A wide variety of functionalized boronic esters and acids have been coupled with simple palladium carboxamides complexes.

Upcycling Water Pollutants Into Long‐Chain Polymers via Synergistic Interfacial Dechlorination and Organic Radical Stabilization

open access: yesAngewandte Chemie, EarlyView.
HEO‐regulated electronic structure drives nonradical PI activation, promoting ETP‐mediated polymerization of 4CP into high‐molecular‐weight products with enhanced surface enrichment. Concurrent dechlorination occurs via radical coupling and •OHads attack, enabling efficient carbon retention and selective product evolution at the liquid–solid interface.

Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

open access: yesAngewandte Chemie, EarlyView.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high

Direct δ‐Lactone Synthesis From Free Alcohols via Photoinduced δ‐C(sp3)–H Carbonylation in Flow

open access: yesAngewandte Chemie, EarlyView.
Herein, we have developed a photo‐flow platform for the δ‐C(sp3)─H carbonylative lactonization of free alcohols with carbon monoxide. The transformation integrates alkoxyl radical generation, selective 1,5‐HAT, CO incorporation, and radical–polar crossover to enable direct access to δ‐lactones from simple alcohol precursors.

Nuclear Waste Disposal

Science, 1982
Problems associated with safe disposal of spent fuel rods, uranium mill tailings, high and low-level nuclear waste are reviewed. The pros and cons of reprocessing, low-level sites, geologic repositories and use of borosilicate waste forms are discussed. (JMT)
