Ultrasonic parameters such as the sound velocity are very sensitive to crystallization and can be used to monitor the crystallization kinetics. The glass-transition temperature has been found to decrease nonlinearly as the CO(2) concentration increases. The maximum in the crystallization rate has been found to increase with the addition of CO(2). (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 112: 1345-1355,

“This study focused on the effect of antimicrobial incorporated soy protein isolate (SPI) coated oriented polypropylene/polyethylene (OPP/PE) packaging on extended shelf life of fresh sprouts. G418 cost To develop antimicrobial SPI-coated packages, the minimum inhibitory and bactericidal concentrations of antimicrobial (allyl isothiocyanate, trans-cinnamaldehyde, garlic oil, and rosemary oil) and film properties of antimicrobial incorporated SPI films were investigated. Different concentrations (0.6-1.2%, v/v) of the SPI incorporated antimicrobial compounds
were coated onto the OPP/PE film and heat-sealed. Packages containing sprouts (alfalfa, broccoli, and radish) were stored at 10 degrees C for 5 days. Significant reduction of the total microbial count of sprouts was observed in treated samples. Allyl isothiocyanate was the most effective antimicrobial compound, followed by garlic oil and trans-cinnamaldehyde. (C) 2009 Elsevier Ltd. All rights reserved.”
“In this study, the selleck compound recently proposed model by Pazuki et al., based on the local composition concept (LCC), has been used in correlating the vapor-liquid phase behavior of polymer solutions. Similar to the LCC models available in the literature, the proposed model has two combinatorial and residual terms to account for both entropic as well as enthalpic effects in solution. The Flory-Huggins model has been considered
as the combinatorial part of the proposed model, while the equation proposed by Pazuki et al. was considered as the residual term. The proposed model has been used in correlating the vapor-liquid phase behavior for a large number of polymer-solvent mixtures at different conditions. The results obtained from the proposed model have been compared with those obtained from the UNIQUAC-FV model. The results showed that the proposed model can accurately correlate the VLE data Compound C chemical structure for polymer solutions studied in this work. Also, the proposed model has been used to obtain the thermophysical properties such as density, viscosity, and excess enthalpy for these polymer Solutions. The results in connection with the thermophysical properties obtained from the proposed model have been compared with those obtained from the Poly-NRTL and the Poly-Wilson models. The results showed that the proposed model can accurately correlate the properties of polymer solutions at various conditions. (C) 2009 Wiley Periodicals, Inc.
