soy protein concentrate (spc) is a functional and nutritional product which is produced under conditions where soy proteins are immobilized in soy flour and soluble carbohydrates are removed. in this study, four different soy flours including defatted soy flour (fat content 3.67, pdi 55.10), defatted and toasted soy flour (fat content 3.78, pdi 10.72), low fat soy flour (fat content 14.34, pdi ...

We have investigated photosensitizing properties for porphrazine and eleven of its related derivatives based on time-dependent density functional theory (TD-DFT) calculations. The modles have been divided into two categories based on the existence of CN functional group in one category but not in the other one. The other functional groups include H, CH3, F, CF3, C6H5, and C6F5 counterparts. The...

Background: Replacement of the gluten is one of the challenging issues in the food industry, since producing nutritious and functionally acceptable gluten-free foods is difficult. The cake is a cereal-based product that attracts the consumers due to its various flavors, long shelf-life, and relatively low cost. Considering the competition in markets and the increased demand for functional and n...

some formulations of drug in adhesive transdermal drug delivery systems ()tddss)( with different functional and non-functional acrylic pressure sensitive adhesives psas)( were prepared. for this purpose fentanyl was used as a drug component. the effects of psas type on skin permeation and in vitro drug release from devices were evaluated using hydrodynamically well-characterized chien permeatio...

native fish gelatin has some disadvantages such as high hydrophilic, and solubility in cold water. mixing with other biopolymers and crosslinking by sugars may improve functional properties of fish gelatin. so in this research, the effects of ribose were investigated on moisture sorption isotherm, solubility in water, and mechanical properties of cold water fish gelatin (cwfg) films. ribose sug...

in the past decades, environmental pollution caused by plastic packing materials, restrictions of petroleum resources and their high price attracted many researchers to produce biodegradable packaging materials. poor mechanic properties and high water vapor permeability are two main defects of biodegradable polymers. nanotechnology is a modification method in this case. in the current study, th...

Food proteins have long been recognized for their nutritional and functional properties. The nutritional properties of proteins are associated with their amino acid content. On the other hand, the functional properties of proteins relate to their contribution to the physiochemical and sensory properties of foods (Sila and Bougatef, 2016). Marine organisms contain proteins with high quantities o...

Cementing of the casing pipes inside the wellbore is considered as one of the most expensive and difficult operations during the well construction process. A low quality cementing job leads to further repair operations, which are usually costly and time-consuming to conduct. Polymer cements are being used for decades in the oil and gas industry due to their improved properties such as sedimenta...

Nanocomposite composed of organoclay(Cloisite 20A-C20A) and Poly lactic acid (PLA) was prepared by solvent casting method. Physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. X-Ray diffraction (XRD) patterns and scannin...

Clusters play important role for understanding and transferring microscopic to macroscopic properties.Geometric and electron properties of Small nickel clusters up to the tetramer has been investigated by Density Functional Theory (DFT). Raising the number of nickel clusters atoms were indicated decreasing the average equilibrium (Ni-Ni) distance of atoms and also the binding energy of per atom...
