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.

Si─Si Bonding in an Unsupported N‐Heterocyclic Silylene Dimer Stabilized by an Iminophosphorane‐Based Scorpionate Ligand Versus Head‐to‐Tail Coordination in the Sn and Pb Tetrylenes

Chemistry – A European Journal, Volume 32, Issue 25, 2 July 2026.
A new iminophosphorane‐based scorpionate ligand enabled the characterization of a head‐to‐head silylene dimer with unsupported Si─Si bonding, whereas the tetrylene species of Sn and Pb afforded head‐to‐tail coordination polymers in the solid state. ABSTRACT N,N‐chelating ligands disfavor element–element bonding in heavier alkene analogs of group 13 and

Exploiting Small-Norm Polynomial Multiplication with Physical Attacks

Transactions on Cryptographic Hardware and Embedded Systems
We present a set of physical profiled attacks against CRYSTALS-Dilithium that accumulate noisy knowledge on secret keys over multiple signatures, finally leading to a full key recovery attack. The methodology is composed of two steps.

Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Privately Generated Key Pairs for Post Quantum Cryptography in a Distributed Network

Applied Sciences
In the proposed protocol, a trusted entity interacts with the terminal device of each user to verify the legitimacy of the public keys without having access to the private keys that are generated and kept totally secret by the user.

Aryl Viologen Polymers in High‐Voltage Full‐Organic Batteries

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
A series of aryl‐viologen polymers is synthesized, and their performance in battery half‐cells is investigated. Pairing the best‐performing polymer with a phenothiazine‐polymer positive electrode creates a full‐organic battery with a high discharge voltage of up to 1.8 V and a specific discharge capacity of 78 mAh g−1.
