Microbiological aspects of ethylene oxide sterilization. IV. Influence of thickness of polyethylene film on the sporicidal activity of ethylene oxide.
Spores of Bacillus subtilis var. niger, dried on nonhygroscopic and hygroscopic surfaces, were enclosed in one of four thicknesses of low-density polyethylene film (2, 4, 6, and 20 mils). The surfaces were then placed in a specially designed thermochemical death rate apparatus and exposed to an ethylene oxide concentration of 600 mg/liter (at 54.4 C) and 50% relative humidity. Survival data, in...
متن کاملMagnetic iron oxide nanoparticles, Polyethylene glycol, Surfactant, Superparamagnetic, Chemical co-precipitation
In this study, magnetic iron oxide nanoparticles (Fe3O4) with the size range of 20-30 nm were prepared by the modified controlled chemical co-precipitation method from the solution of ferrous/ferric mixed salt-solution in alkaline medium. In this process polyethylene glycol was used as a surfactant to prevent the solution from agglomeration. The prepared magnetic nanoparticles were characterize...

متن کاملFormation of Polyethylene Glycol on Montmorillonite by Sterilization with Ethylene Oxide
-The effect of ethylene oxide-sterilization on homoionic (Na +, K § Ca 2+, Cu 2+, A1 s+, and Fe 3+) montmorillonite samples was examined. The results indicate that ethylene oxide polymerized to polyethylene glycol in the interlayer of Cu 2+-, AP +-, and FeS+-saturated clays, as substantiated by the increase in the d(001) values, as well as by the decrease in the cation-exchange capacity after r...
متن کاملIon Conduction in Oriented Domains in Poly(ethylene-oxide)-Polyethylene Systems
The ionic conductivity of LiSO3CF3 complexed with wax-like solids of the general form H-(CH2)32 (CH2CH2O)10-H were investigated. The conductivity of the waxes studied in this work should be dependent on the shape of the domains. Conductivity measurements were made perpendicular, σ⊥, and parallel, σ, to the direction of molecular orientation. Depending on the size of the conducting domains, an...
