Core cross-linked star (CCS) copolymers were prepared by reversible addition–fragmentation chain-transfer polymerization according to the arm-first technique and studied as viscosity index improvers for application in hydraulic lubricants. A one-pot two-step synthetic procedure was optimized: starting from PMA arms with a precisely controlled structure three different molecular weights using am...

objective: hexavalent chromium [cr (vi)] compounds are well-known environmental contaminants  generated from industrial processes. several studies have reported the harmful effects of cr (vi) on different organs, however, little is known about neurotoxic effects of cr (vi). the aim of this study is to investigate the toxic effects of cr (vi) on pc12 cells. methods: pc12 cells were cultured foll...

Abstract The paper summarizes, after defining the meaning and agreed-upon usage of crucial key-concepts, different perspectives participants 10th Symposium Plant Protection Health International held on 23rd November 2021 “Biostimulants, soil improvers, bioprotectants: promoters bio-intensification in plant production” state art research this topic. In total, 254 from 24 countries around world p...

Methyl ricinoleate was functionalized using thiol-ene click chemistry in order to synthesize bio-based comb (co)poly(9-alkyl 12-hydroxystearate)s. The latter were then evaluated as Viscosity Index Improvers a mineral based lubricant. While most of the poly(9-alkyl 12-hydroxystearate)s investigated behave thickeners, copolyesters containing 15 25 wt% methyl 9-phenyl ethyl 12-hydroxystearate exhi...
