Baikal endemic and Palearctic species of caddisflies (Trichoptera) build cases from microplastics

Acta Biologica Sibirica
Pollution of freshwater ecosystems by microplastics is a serious problem. Many studies are related to the pelagic zone and the organisms living in it. However, benthic organisms are most susceptible to this problem in aquatic ecosystems.

Verfolgung von Strukturellen Verzerrungen und Orbitalbesetzung während Spin Crossover Prozessen in Metallkomplexen mittels Liganden K‐Kanten Spektroskopie

Angewandte Chemie, EarlyView.
Stickstoff‐K‐Kanten XAS‐ und RIXS‐Messungen zeigen Signaturen struktureller und elektronischer Relaxation während der photoinduzierten Spin Crossover‐Kaskade von Eisen‐(II)‐Tris(Bipyridin). Oszillationen der 1s→π∗$1s\rightarrow \pi ^*$ Übergangsenergie stehen in Zusammenhang mit der Änderung der Fe‐N‐Bindungslänge.

Microplastics in Sediments of the Littoral Zone and Beach of Lake Baikal

Limnological Review
Most studies on microplastic pollution in aquatic ecosystems have focused on the quantitative and qualitative assessment of particles in surface waters. However, the highest concentrations and accumulation of microplastic particles are observed in bottom

Tracing Structural Distortions and Orbital Population During Spin‐Crossover in Transition Metal Complexes via Ligand K‐edge Spectroscopy

Angewandte Chemie International Edition, EarlyView.
Nitrogen K‐edge XAS and RIXS reveal signatures of structural and electronic relaxation in the photo‐induced spin‐crossover cascade of iron‐(II)‐tris(bipyridine). Oscillations of the 1s→π∗$1{\rm s} \rightarrow \pi ^*$ transition energy are correlated with the transient elongation of the Fe─N bonds.

Phenonium‐Ion‐Mediated Skeletal Editing of Paracyclophanes

Angewandte Chemie International Edition, EarlyView.
Phenonium‐ion chemistry enables the modular skeletal editing of paracyclophanes. Regioselective nucleophilic trapping expands one or both aliphatic bridges, enables iterative access to higher paracyclophane homologues, and translates bridge topology into a functional design parameter, as demonstrated with a bridge‐expanded TADF emitter.
