Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.Die geminale Difunktionalisierung leicht verfügbarer Bausteine ermöglicht einen schnellen Zugang zu molekularer Komplexität. Diese Arbeit stellt eine Strategie vor, um zwei unterschiedliche funktionelle Gruppen an einem Carbonylkohlenstoff zu installieren, indem dieser in eine Donor–Donor‐Diazo‐Verbindung überführt wird. Die Methode ist sowohl im Batch‐

Laufzeitmessungen in Fluoren-Einkristallen / Transit Time Measurements in Fluorene Single Crystals
Zeitschrift für Naturforschung A, 1977 Abstract The hole drift mobility in single crystals of fluorene was determined by transit time measurements. At room temperature the mobility along the c-axis is (0,82 ± 0,14) cm2/Vs and in the abplane (0,72 ± 0,1) cm2/Vs. In the temperature ranges 200K<T<300K and 165K<T<300K μc and μab have been found to be ~T-1,5 and ~T-1 ...

Fluorescent Nanosensor for Indole‐3‐Propionic Acid Detection in Gut Health Monitoring
Advanced Healthcare Materials, Volume 15, Issue 21, 5 June 2026.This work introduces a fluorescent nanosensor system with two optical modalities for detection of indole‐3‐propionic acid (IPA) gut metabolite: (1) blue‐emitting cationic conjugated polyelectrolyte (CP3) and (2) near‐infrared (NIR)‐emitting CP3‐wrapped single‐walled carbon nanotube (SWNT).

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.Wir berichten, dass nicht‐zytotoxische, polyfluoralkylierte zellpenetrierende Peptide (CPPs) als CPP‐Additive die intrazelluläre Proteinaufnahme signifikant verbessern, indem sie die Membranverweildauer der CPP‐Additive erhöhen. Durch die Kombination von biophysikalischen Experimenten und Molekulardynamiksimulationen zeigen wir zudem, dass die ...

Tar Removal From Biomass‐Derived Syngas via Scrubbing: A Review on Process and Modeling
ChemBioEng Reviews, Volume 13, Issue 3, June 2026.This review article surveys contaminant formation and removal in biomass‐derived syngas, with a focus on tar scrubbing. It synthesizes evidence from benchmark plants and compares scrubbing configurations and solvents to assess performance and operating limits.

Angewandte Chemie, Volume 138, Issue 21, 18 May 2026.A Pd‐catalyzed regioselective synthesis of benzylsilanols from Kobayashi‐type reagents has been developed through a mechanistically distinct approach involving 1,4‐Pd migration followed by intramolecular transmetalation. The reaction can be combined with various prior transition‐metal‐catalyzed processes and the resulting benzylsilanols have been ...
