Small-angle neutron scattering was used to investigate poly(N-isopropylacrylamide) (PNIPAM) polymer solutions in d-water/d-ethanol mixtures. A wide poor-solvent region was observed for mixtures near 60% d-water/40% dethanol mixture. Spinodal lines were determined, permitting a mapping of the mixing/demixing regions of the phase diagram which comprises two main branches: the left branch (with mo...

The effect of different rates of ethanol additive on fermentation quality of napiergrass (Pennisetum purpureum) and residual water soluble carbohydrate were studied in the experiment. The addition rate of ethanol was 0%, 1.5%, 2.5%, 3.5%, 4.5% on fresh weight of napiergrass. The laboratory silos were kept in the room, then were opened on 1, 3, 5, 7, 14, 30 days after ensiling and the changes of...

Robert M. Kaiser University of Wisconsin-Extension Dairy Agent Introduction Across the Midwest, ethanol plants (primarily dry mill vs. wet mill process) are being planned and built and existing plants expanded. Today over 98 percent of commercially produced ethanol is used to extend gasoline. The attributes of ethanol allow it to be utilized as an octane booster, replacing gasoline additives su...

The functionality of gluten extracted from Canada Western Red Spring (CWRS) and Canada Western Extra Strong (CWES) wheat flours was evaluated and compared. The extra-strong wheat cultivars had stronger dough properties and produced smaller bread loaves than AC Barrie. Modifications of a starch displacement gluten extraction method were evaluated. For optimal gluten formation and extraction, wat...

serum albumin is the most abundant protein in blood plasma. its two major roles are maintaining osmoticpressure and depositing and transporting compounds. in this paper albumin-ethanol/water solutionssimulations are carried out by three techniques including monte carlo (mc), molecular dynamic (md) andlangevin dynamic (ld) simulations in aqueous solutions. investigation the energy changes with t...

The solubility of polymers can be significantly altered by the use of solvent mixtures. The solvent composition also effects the self-assembly properties of amphiphilic copolymers. In addition, water–ethanol mixtures are known to exhibit abnormal physicochemical properties due to the presence of hydration shells around the ethanol molecules, while at the same time both solvents have very low to...

Bamboo timber is very vulnerable to mould fungi, a characteristic that is attributed to the rich sugar, starch, and protein present in bamboo. Solvents including cold water, hot water, benzene/ethanol, ethanol/ether, 1% NaOH, and 1% HCl can dissolve corresponding components from bamboo, which might be helpful to the resistance of bamboo against mould fungi. In order to study the relationship be...

The solubility of glycine, diglycine, and triglycine was investigated in water-ethanol mixtures (20% and 50% ethanol) as a function of the temperature. The transfer free energy, @go,,,, for the peptide group was evaluated and the separate enthalpy and entropy components of the transfer process were determined. In 20% ethanol solutions, the hypothesis of additivity of the contribution of various...

Delay in gastric emptying (GE) lowers the blood ethanol concentration (BEC) after alcohol administration. We previously demonstrated that water-insoluble fractions, mainly comprising dietary fiber derived from many types of botanical foods, possessed the ability to absorb ethanol-containing aqueous solutions. Furthermore, there was a significant correlation between the absorption of ethanol and...
