Inversion of the X-ray restrained wavefunction equations: a first step towards the development of exchange-correlation functionals based on X-ray data. [PDF]

J Appl Crystallogr
The X‐ray restrained wavefunction (XRW) approach could be a useful tool to propose new exchange–correlation (xc) functionals for density functional theory. Here, orbital‐averaged XRW perturbation potentials of atoms (neon, argon and krypton) and simple molecules (dilithium and urea) are extracted and visualized for the first time, and their possible ...

PACE—Plantard Accelerated CRYSTALS Extensions

IEEE Access
ML-KEM (FIPS203) and ML-DSA (FIPS204) were two of the first post quantum cry- ptography schemes to be standardized by the National Institute of Standards and Technology; Both CRYSTALS algorithms utilize modulo reduction, specifically Montgomery reduction.

Dilithium Enediamide Derived From 1,4‐Diaza‐1,3‐Diene: An Electron Reservoir Enabling Variable Reactivity Toward Carbonyl Compounds

European Journal of Inorganic Chemistry, Volume 29, Issue 21, 25 July 2026.
Upon reduction of 1,4‐diaza‐1,3‐diene 1 to the dilithium enediamide 2, the polarity of the C = N bonds is reversed ‐ a classic case of umpolung. This behavior is particularly evident in reactions of the dianion 2 with carbonyl compounds and also explains why 1,4‐diaza‐1,3‐diene ligands do not always act merely as spectator ligands. 1,4‐Diaza‐1,3‐dienes

Dilithium Enediamide Derived From a 1,4‐Diaza‐1,3‐diene: Reactivity of a Strongly N‐Basic, Highly C‐Nucleophilic Compound Toward C–H Acids

European Journal of Inorganic Chemistry, Volume 29, Issue 20, 17 July 2026.
The lithium enediamide complex 2 with intrinsically inverted C–N bond polarity combines strong basicity with unusual reactivity: deprotonation of malonates enables C–C bond formation without electron transfer. Depending on malonate substitution, electrophilic substitution or addition occurs at the enediamide CC bond.
