Terahertz Spectroscopic Imaging of Polymorphic Forms in Pharmaceutical Crystals

, 2018
A terahertz spectroscopic imaging system was fabricated for the detection of two-dimensional molecular distributions in pharmaceutical tablets based on absorption peaks of intermolecular or intramolecular hydrogen bonds in crystals. The terahertz imaging

Single-Trace Side-Channel Attacks on CRYSTALS-Dilithium: Myth or Reality? [PDF]

, 2023
We present a side-channel attack on CRYSTALS-Dilithium, a post-quantum secure digital signature scheme, with two variants of post-processing. The side-channel attack exploits information leakage in the secret key unpacking procedure of the signing ...

Homogenization‐confined‐repair regeneration of spent LiFePO4 cathodes via tunable pre‐oxidization and microencapsulation strategy

InfoMat, Volume 8, Issue 1, January 2026.
The HCR‐DR method combines pre‐oxidation and NIPS to synchronize atomic defect repair with structural engineering. Pre‐oxidation converts S‐LFP into stoichiometric intermediates, eliminating residual binder and carbon. Ethanol‐induced NIPS of PVA forms porous microcapsules with confined Li2CO3/glucose around S‐LFP‐Air particles. Annealing pyrolyzes PVA

2,3‐Diboratabutadiene Complexes of Group 4 Metals and their Donor‐Induced Oxidative Cleavage to Methyleneboranes

ChemistryEurope, Volume 3, Issue 6, November 11, 2025.
GA: We here report the first perarylated 2,3‐diboratabutadiene dianion and its reaction with Cp2MCl2 (M = Zr, Hf) to afford unprecedented 2,3‐diboratabutadiene π‐complexes with unique coordination modes. Addition of an N‐heterocyclic carbene (NHC) to the complexes gives rise to the donor‐induced oxidation of the BB bond, resulting in two separate NHC ...
