In the current study, whey protein- pullulan- clay nanocomposite films are prepared by casting method. The effect of nanoclay at three concentrations (1%, 3% and 5%) on physical properties such as moisture content, solubility in water, water vapor permeability and transparency of whey protein- pullulan composite films investigated. The results show that the effect of nanoparticles on composite ...

Cationic dye Acridine orange (AO) has wide applications especially in biologicalfields such as analysis of lysosomal and mitochondria content by flow cytometryand so on. In the current work, spectroscopy of acridine orange (AO) dye at bothlow concentrations (mdye/mwater=6.25×10-5, 3.12×10-5) and high concentrations(mdye/mwater=0.002, 0.001) was studied in confined water ...

Agricultural waste fibers have been found to be suitable as reinforcement in cement-based composites, but studies on oil palm fiber as reinforcement in gypsum-cement wall panels are scarce. A mixture of two equal weights of gypsum and cement, with water-binder ratios of 0.45 and 0.55 were prepared. In each mix a varying percentage of fiber contents of 2%, 3% and 4% by weight of the binders were...

Methylene Blue, Reversed Micelles, Water Content, Solubilization The solubilization of methylene blue in dodecylammonium propionate reversed micelles in cyclohexane depended strongly on the solubilized water content. Methylene blue solubilized in the micelle of which head groups are not completely hydrated by bound water exhibited the new absorption bands at 495 and 270 nm, but these bands did ...

sorption isotherm and thermal properties of powders were used for determining stability during storage. garlic slices with 2 mm thickness were dried, using two methods of freeze and cabinet drying. the results showed that, the density, loss of pyruvate and color changes of the freeze dried powder were less than those of the cabinet dried powder. sorption isotherm curves of the both garlic powde...

Biogeochemical processes in plants, such as photosynthesis, evaporation and net primary production, are directly related to foliar water. Therefore, canopy water content is important for the understanding of the terrestrial ecosystem functioning. Spectral information related to the water absorption features at 970 nm and 1200 nm offers possibilities for deriving information on leaf and canopy w...
