Partially Biobased Self‐Repairing Poly(Aspartic Ester Polyurea) Coatings

open access: yesPolymer Engineering &Science, Volume 65, Issue 8, Page 4155-4169, August 2025.
Sustainable self‐healing PAEU coatings, containing various amounts of disulfide derived from poly(aspartic esters) and biobased polyisocyanates, were created. ABSTRACT Poly(aspartic ester polyurea) (PAEU) coating systems, which feature an uncatalyzed and solventless reaction, have attracted attention as a more environmentally friendly, nonreactive ...

Membran‐Bioreaktor‐Technik kombiniert mit nachgeschalteter Ozonung – Vergleich mit konventionellen Ozonanwendungen Combination of Membrane Bioreactor and Downstream Ozonation – A Comparison to Conventional Ozone Applications

open access: yesChemie Ingenieur Technik, Volume 97, Issue 7, Page 677-688, July 2025.
Kommunale Kläranlagen gelten als Haupteintragspfad organischer Mikroschadstoffe in die aquatische Umwelt. Ein Großteil der Arzneimittelrückstände und Industriechemikalien wird in Kläranlagen nicht oder nur teilweise entfernt. Um einen qualitativ höheren Kläranlagen‐Ablauf zu erzeugen, wird eine Kombination aus hybridem Teilstrom‐Membran‐Bioreaktor mit ...

Identification of inhibitors of the Salmonella FraB deglycase, a drug target

open access: yesFEBS Open Bio, Volume 15, Issue 5, Page 773-792, May 2025.
A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.
