Without intervention, it has been found that surface-initiated photoiniferter-mediated photopolymerization (SI-PMP) of methyl methacrylate suffers from irreversible termination, which leads to cessation of polymerization. These irreversible termination reactions were successfully reduced by preaddition of tetraethylthiuram disulfide (TED). The poly(methyl methacrylate) layers were also reinitia...

The process of radical binary copolymerization butyl methacrylate and α-methyl styrene in a solvent has been carried out optically transparent copolymers at various molar ratios have synthesized. synthesized based on relatively high refraction coefficient ( =1.5880) transmission values (about 86%). constants (r1 r2) the above-mentioned monomer pairs found Q-e parameters calculated. microstructu...

background: lipase is an enzyme with immense application potential. ester synthesis by lipase catalysis in organic media is an area of key industrial relevance. enzymatic preparations with traits that cater to the needs of this function are hence being intensely researched. objective: the objectives of the study were to immobilize the lipase from bacillus sp. ps35 by cross-linking and adsorptio...

An isolated strain of Fusarium oxysporum from the hulls of Prunus dulcis (sweet almond) was found to produce relatively large quantities of the hydrocarbons styrene and two isomers of 7-methyl-1,3,5- cyclooctatriene (MCOT). Production of styrene and MCOT was reproduced on a small scale using potato dextrose agar as a growth medium and scaled up using 1 L of inoculated potato dextrose broth. The...
