Identification of microplastic pathways within a typical European urban wastewater system
Applied Research, Volume 2, Issue 5, October 2023., 2023 Stormwater retention tanks can be a serious sink of microplastic particles, and hence a possible source of input into the environment. Abstract In recent years, thermoextraction/desorption‐gas chromatography/mass spectrometry (TED‐GC/MS) has been developed as a rapid detection method for the determination of microplastics (MP) mass contents in numerous

Nasschemische Bottom‐up Synthese von Graphen‐Nanostreifen mit atompräzisen Nanoporen
Angewandte Chemie, Volume 135, Issue 35, August 28, 2023., 2023 Der poröse Graphen‐Nanostreifen pGNS wurde als erster seiner Art durch nasschemische bottom‐up Synthese erhalten. Schlüssel zu dieser Struktur ist ein rational entworfenes und atomgenau synthetisiertes Polyphenylen, welches die hexagonalen Nanoporen bereits als Strukturelement enthält, was pGNS mit einem vollständig konjugierten aromatischen Kern und ...
