Wharton's Jelly Mesenchymal Stromal Cell‐Derived Extracellular Vesicles Attenuate Intervertebral Disc Degeneration Under Inflammatory Stress in an In Vitro 3D Culture System

JOR SPINE, Volume 8, Issue 3, September 2025.
This study explores the therapeutic potential of extracellular vesicles (EVs) derived from Wharton's Jelly mesenchymal stem cells in an in vitro 3D model of intervertebral disc degeneration under inflammatory stress. The treatment with WJ‐MSC‐EVs enhanced nucleus pulposus cell proliferation, viability, and extracellular matrix synthesis while reducing ...

Peroxide‐Driven Nitrogen Fixation Reactions for Energy Storage Applications

Advanced Energy Materials, Volume 15, Issue 32, August 26, 2025.
Sustainable ammonia synthesis from air as a hydrogen energy carrier and storage medium is demonstrated via an efficient dual‐step electrochemical approach at ultralow overpotential (−0.1 V vs. RHE). Atmospheric nitrogen is first oxidized to nitrate using in situ generated peroxide, then directly converts to ammonia on the same electrode, achieving ...

Dinitroacetylene: Can It be Made?

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 4, April 2025.
With a predicted record‐high heat of formation, energy density, and outstanding performance as a rocket propellant, dinitroacetylene stretches the imagination for what is possible in terms of organic chemical explosives and monopropellants. In this study, we employ quantum chemical methods to assess the isolability and kinetic stability of this ...

Catalytic Metal Nanoparticles Embedded in Conductive Metal–Organic Frameworks for Chemiresistors: Highly Active and Conductive Porous Materials

Advanced Science, Volume 6, Issue 21, November 6, 2019., 2019
Ultra‐small and well‐dispersed metal nanoparticles (NPs) are embedded in the cavities of 2D conductive metal–organic frameworks (C‐MOFs), for the synthesis of highly active and porous conductive materials. The catalytic metal NPs‐loaded C‐MOFs exhibit dramatically improved NO2 sensing performance at room temperature, due to the high reactivity of ...

Benzofuroxans: A Possible +100 Years Old Misunderstanding?

ChemPhysChem, Volume 26, Issue 3, February 1, 2025.
Since 1912 benzofuraxans have been believed to be constituted by a benzene ring fused with a pentatomic ring (a N−O−N bridge) and a N+→O− bond. A careful analysis of the electronic and topological properties of strategic representatives of this class of compounds, compared to the corresponding benzofurazans, revealed a different interpretation ...
