Dibenzazepin‐verbrückte Netzwerk‐Polymer‐Phthalocyanine als abbaubare heterogene Photokatalysatoren

Angewandte Chemie, EarlyView.
Photodynamische Dibenzazepin‐Brücke wurde in Zink‐ und Kobalt‐Netzwerk‐Polymer‐Phthalocyanine (NP‐Pcs) eingeführt, um abbaubare heterogene Photokatalysatoren zu erhalten. Zum ersten Mal spielt die Bestrahlung mit Licht eine Schlüsselrolle beim „Design, der Verwendung und dem Abbau” von NP‐Pcs.

Comparing Transcriptomic Responses to Chemicals Across Six Species Using the EcoToxChip RNASeq Database

Environmental Toxicology and Chemistry, EarlyView.
Abstract The EcoToxChip project includes RNA‐sequencing data from experiments involving model (Japanese quail, fathead minnow, African clawed frog) and ecological (double‐crested cormorant, rainbow trout, northern leopard frog) species at multiple life stages (whole embryo and adult) exposed to eight chemicals of environmental concern known to perturb ...

Effect of structural disorder induced by external irradiation with heavy ions on the alteration of a four oxide borosilicate glass

npj Materials Degradation
The irradiation of glass by heavy ions induces structural damage, generally leading to a decrease in its chemical durability whose amplitude strongly depends on the glass chemical composition.

Impact of B and Al on the initial and residual dissolution rate of alumino-borosilicate glasses. Part I: kinetic data

npj Materials Degradation
Nuclear glasses are made of highly soluble (B) and low soluble (Si, Al) glass formers. This paper investigates the influence of these two types of elements on the initial and residual alteration rates of 6-oxide borosilicate glasses with varying B and Al

Electrolyzed saline as an alternative to chlorhexidine: Antimicrobial and biofilm volume outcomes in a 4‐day non‐brushing randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background The biofilm‐inhibitory effects of electrolyzed saline (EOS) vary widely due to differences in formulations and treatment methods. This study analyzed the impact of EOS on key oral microbial species and used serial 3D‐intraoral scans to evaluate its effects on de novo biofilm formation.

Microstructure‐dependent abrasive wear behavior of metallic alloys under tumbling abrasion Mikrostrukturabhängiges abrasives Verschleißverhalten metallischer Legierungen unter Trommelabrieb

Materialwissenschaft und Werkstofftechnik, EarlyView.
This study assesses the abrasive wear behavior of eight metallic alloys using the SSAB tumbling abrasion test under low‐stress wet grinding with quartz sand and iron ore. Results highlight the role of microstructure—particularly carbide morphology and hardness—in optimizing grinding media for mineral processing applications.
