The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

Bis(2-pyridylmethyl)ammonium perchlorate

Acta Crystallographica Section E Structure Reports Online, 2002
The title compound, C14H18N3+·ClO4−, a perchlorate salt of the monoprotonated form of bis(2-pyridyl­ethyl)­amine, has a structure in which one of the two H atoms on the amine N atom forms hydrogen bonds to the two pyridyl N atoms in a chelating fashion, while the second H atom on the amine is also used in hydrogen bonding to a perchlorate O atom.

Overcoming Interfacial Hurdles in Solid‐State Aluminum Batteries for Safe and Energy‐Dense Storage

Advanced Science, Volume 13, Issue 45, 13 August 2026.
Solid‐state aluminum batteries (SSABs) promise high energy density and intrinsic safety but face severe solid–solid interfacial challenges. This review reveals the three core hurdles—anode passivation, cathode contact loss, and electrolyte grain boundary resistance and discusses strategies including artificial interphases, alloying, and composite ...

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1224-1234, August 2026.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

On the Alternative Protonation of Heterocyclic Michler´s Ketone Analogues

ChemistrySelect, Volume 11, Issue 32, 24 August 2026.
Bis(5‐aminothionyl)ketones exhibit a significant bathochromic shift in the UV–vis absorption spectrum and form deeply violet proton adducts under acidic conditions. NMR spectroscopy and quantum chemical calculations confirm that O‐protonation occurs. In contrast, protonation of the amino groups in Michler´s ketone and the heterocyclic aza moieties in ...
