Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

Advanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

Metabolic‐Redox Remodeling of Inflammatory Synovium by Mannose‐Modified Selenium Nanoparticles for Osteoarthritis Therapy

Advanced Science, EarlyView.
Elevated GLUT1‐driven glycolysis and disrupted selenoprotein‐dependent redox homeostasis drive osteoarthritic progression. Intra‐articular mannose‐modified selenium nanoparticles (M‐SeNPs) selectively target hypermetabolic synovial cells to reprogram aberrant glycolysis and restore endogenous antioxidant defenses.

Total Synthesis of the Sesquiterpene (±)-Illudin C via an Intramolecular Nitrile Oxide Cycloaddition

, 2016
A convergent total synthesis of illudin C is described. The tricyclic ring system of the natural product was quickly assembled from cyclopropane and cyclopentene precursors via a novel oxime dianion coupling reaction and a subsequent intramolecular ...

Interfacial Salt Redistribution Enables Rapid Atmospheric Water Harvesting in a Biomimetic Multi‐Layer Hygroscopic Membrane

Advanced Science, EarlyView.
A biomimetic multi‐layer hygroscopic membrane redistributes salt toward an air‐accessible nanofiber interface, enabling rapid interfacial deliquescence while a brush‐like hydrogel promotes efficient liquid transport and storage. By decoupling vapor capture from bulk water storage, the membrane achieves fast sorption kinetics and enables rapid‐cycling ...

Ionic elastomers based on carboxylated nitrile rubber (XNBR) and magnesium aluminum layered double hydroxide (hydrotalcite)

eXPRESS Polymer Letters, 2014
The presence of carboxyl groups in carboxylated nitrile butadiene rubber (XNBR) allows it to be cured with different agents. This study considers the effect of crosslinking of XNBR by magnesium aluminum layered double hydroxide (MgAl-LDH), known also as ...

H4K12 Lactylation Impairs Dopaminergic Neuron Energy Metabolism via the HIF‐1α/NDUFS1 Pathway in Parkinson's Disease

Advanced Science, EarlyView.
Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

Mn/Zn Bimetallic MOF‐Integrated Hydrogel Alleviates Excessive Mitochondrial Fission in BMSCs to Promote Osteoporotic Jawbone Repair

Advanced Science, EarlyView.
Excessive reactive oxygen species (ROS) and chronic inflammation impair bone marrow‐derived mesenchymal stem cells (BMSCs), contributing to poor healing in osteoporotic jawbone defect. The gelatin methacryloyl hydrogel loaded with manganese‐doped zeolitic imidazolate framework (Mn‐ZIF‐8@GelMA) promotes regeneration through redox regulation and ...
