Effect of Chalcogen Interaction on the Structure of Methine‐Bridged Trichalcogenophenes
Chemistry – A European Journal, Accepted Article.Polythienylenemethylidenes (PTMs) are promising conjugated polymers for organic electronics owing to their narrow bandgaps and extended π‐conjugation. However, their stereochemistry remains unexplored. In this study, methine‐bridged trithiophene and trifuran analogs were synthesized to investigate stereochemistry and chalcogen bonding effects.

Chemistry – A European Journal, EarlyView.Highly reactive (aza)quinone methides are electrophiles generated from many stimuli‐responsive prodrugs and probes. A new linker has been designed to quench the electrophilic methide, forming a tetrahydroisoquinoline (THIQ) heterocycle in high yields, even when a competing nucleophile is present.

ECDSA White-Box Implementations: Attacks and Designs from CHES 2021 Challenge
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Despite the growing demand for software implementations of ECDSA secure against attackers with full control of the execution environment, scientific literature on ECDSA white-box design is scarce. The CHES 2021 WhibOx contest was thus held to assess the

Synthesis and Biological Evaluation of Bicyclic Pyrazolines with Promising Antimicrobial Activities
ChemMedChem, EarlyView.Continuous flow technology is exploited for the generation of bicyclic pyrazolines via photo‐click reactions. These heterocyclic species contain a valuable 3D scaffold along with a polar succinimide moiety. Subsequent antimicrobial testing reveals that halogenated moieties such as chlorine atoms and trifluoromethoxy groups enhance the potency of these ...

Real-time encryption and authentication of medical video streams on FPGA [PDF]
, 2016 This work presents an FPGA-based solution for the encryption and authentication of video streams of surgeries. The most important is minimal latency. To achieve this, a block cipher with an authenticated mode of operation is used.
