Cationic ring-opening polymerization (CROP) of 2-ethyl-2-oxazoline (EtOx) was systematically investigated in benzotrifluoride (BTF), which is considered as an environmentally less harmful solvent than many conventional reaction media. Simultaneously, polymerizations solvents, such acetonitrile, N,N-dimethylacetamide and toluene, were also carried out for comparison the 80–100 °C temperature ran...

The photochemical dynamics of three classes organic photoredox catalysts employed in organocatalyzed atom-transfer radical polymerization (O-ATRP) are studied using time-resolved optical transient absorption and fluorescence spectroscopy. nine selected for study examples N-aryl core-substituted dihydrophenazine, phenoxazine phenothiazine compounds with varying propensities control outcomes. Exc...

The murine-virus-infected erythroleukemia cell system provides an opportunity to examine regulatory mechanisms controlling cytodifferentiation. A cloned cell line (DR10c3) resistant to the erythropoiesis-inducing effect of dimethylsulfoxide (Me2SO) was isolated from the Me2SO-sensitive line DS19. DR10c3 is characterized as follows: (1) the uptake of [3H]Me2SO is similar to that in DS19; (2) cel...

modified cellulose acetate (ca) membranes were prepared by dissolving the polymers in a mixture of acetone (ac) and n, n dimethylacetamide (dmac) (70:30) solvent and deionized (di) water was used in the coagulation bath. the introduction of polyethylene glycol (peg) additive and tio2 nanoparticles (nps) into the casting solution has changed the structures of the resulting membranes during the p...
