, 2002 In den letzten Jahren ist die Nachfrage nach Datenspeichern und ihrer Speicherkapazität immer größer geworden. Dazu sind neue Speichermaterialien notwendig sind, wofür sich in vielen Fällen polymere schaltbare Materialien eignen.Aus diesem Grunde wurden in der vorliegenden Arbeit polymergebundene Nitrone hergestellt, um diese als photoreaktives ...

ChemElectroChem, Volume 12, Issue 13, July 3, 2025.N‐methyl‐nitroaryl‐furanyl‐nitrone (LQB‐569) suffers a 10‐electron reduction, forming a hydrazine group with two terminal hydroxylamine groups. Nitrones’ antioxidant capacity (AO), despite being very low, correlates with their oxidation profiles, and the ones able to oxidize more easily have better results on DPPH• scavenging and ferric‐reducing ...

Emerging Therapeutic Strategies for Hearing Loss
Advanced Therapeutics, Volume 8, Issue 7, July 2025.Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or

Valdiazen Derivatives for Chemoproteomic Studies in Burkholderia cenocepacia H111
ChemBioChem, Volume 26, Issue 11, June 3, 2025.Valdiazen is a quorum‐sensing signal isolated from B. c. H111. Using diazeniumdiolate chemical probes, several valdiazen‐binding proteins are identified, many of which are involved in structural and metabolic processes. This study offers valuable chemical tools and advances our understanding of the interactome associated with diazeniumdiolate signaling
