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 ...

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 ...

International Journal of Photoenergy, Volume 3, Issue 3, Page 161-169, 2001., 2001 The discoveries that nitric oxide (a.k.a. nitrogen monoxide) serves important roles in mammalian bioregulation and immunology have stimulated intense interest in the chemistry and biochemistry of NO and derivatives such as metal nitrosyl complexes. Also of interest are strategies to deliver NO to biological targets on demand. One such strategy would be

core
Advanced Energy Materials, Volume 14, Issue 37, October 4, 2024.A bio‐inspired, reduced molybdenum oxide catalyst supported on a dendritic nickel foam core (MoOx/NiNF) is reported. The MoOx/NiNF electrocatalyst displays faradaic efficiencies (FE) of up to 99% for the reduction of nitrate to ammonia and maintains an average FE of ≈83% for over 3100 h of operation at −650 mA cm−2.
