Plasmonic‐Hydrogel Hybrid Biomaterials Via In Situ Seeded Growth

Angewandte Chemie, EarlyView.
Detailed chemical analysis of the interactions between Au3+ ions and gelatin‐based hydrogels enables the development of a robust “in situ” seed‐mediated synthesis of plasmonic gold nanoparticles, whereby gold salts are reduced directly on the surface of hydrogel substrates to form the nanostructures.

Silver(I) pyridinyl complexes with benzothiazole, thiophene, and furan moieties: DNA/protein‐binding, antibacterial, antioxidant, and anticancer studies

Archiv der Pharmazie, Volume 356, Issue 1, January 2023., 2023
Nine Ag(I) complexes of Schiff bases containing thiophene, furan, and pyridine moieties were synthesized and tested for their in vitro antibacterial, antioxidant, and anticancer activities and DNA/bovine serum albumin binding. The nine Ag(I) complexes bound to calf thymus‐DNA by an intercalative binding mode, with the complex bearing a benzothiazole ...

Introducing Photochemical Action Plots as a Tool for Unlocking On–Off Switchable Behavior in a Polymeric Eosin Y Photocatalyst

Angewandte Chemie, EarlyView.
The photochemical action plot methodology developed by the Barner–Kowollik team provides a powerful tool for the investigation of the wavelength dependence of light‐driven reactions. Herein, the methodology is applied to a photocatalytic reaction, resulting in the first examples of photocatalytic action plots.

Correlates of avian extinction timing around the world since 1500 CE

Avian Research
Avian extinctions have been relatively well documented in modern history, and in the past millennia, more bird species are known to have gone extinct than species in any other vertebrate class.

Endosymbiotic ratchet accelerates divergence after organelle origin

BioEssays, Volume 45, Issue 1, January 2023., 2023
Primary endosymbiosis gave rise to mitochondria and plastids. The proximate impacts of organelle origin on lineage evolution have not been addressed at the population level. Using data from the photosynthetic amoeba Paulinella, we hypothesize that primary endosymbiosis accelerates lineage divergence, a process we refer to as the endosymbiotic ratchet ...

Aza‐Diphosphazenanes: Inorganic Cyclohexane‐like Connectors with Stereochemically Tunable Exit Vectors for Molecular and Macromolecular Chemistry

Angewandte Chemie, EarlyView.
New aza‐diphosphinanes have been prepared and a model has been developed to explain their cis/trans isomerization. Two‐fold oxidation leads to new aza‐diphosphazenanes as robust inorganic connectors with selectable stereochemistry. Polycondensation reactions results in the first inorganic cyclo‐linear polyphosphazenes which have high‐molecular weights ...
