Modelling fouling induction periods [PDF]

open access: yesInternational Journal of Thermal Sciences, 2012
Abstract A fouling process is often preceded by an induction period in which no significant fouling is observed. In this paper, a simple lumped parameter model based on fractional surface coverage θ has been developed to correlate experimental data in the induction period.

Effect of hemoglobin concentration on the oxidation of linoleic acid

open access: yesJournal of Lipid Research, 1971
The inhibitory effect of high concentrations of hemoglobin on the oxidation of linoleic acid was related to the ability of hemoglobin to associate with the fatty acid. Ultracentrifugation of the mixture of hemoglobin and potassium linoleate revealed that

A novel profluorescent dinitroxide for imaging polypropylene degradation [PDF]

open access: yes, 2008
Free-radical processes underpin the thermo-oxidative degradation of polyolefins. Thus, to extend the lifetime of these polymers, stabilizers are generally added during processing to scavenge the free radicals formed as the polymer degrades.
