the purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. the size of the nano-emulsion and the ph of nano-emulsion were characterized. ultrasound has been used for preparing emulsion by 24 khz intensity for 120 seconds. prepared nano-emulsion was investigated by pa...

Curing is one of the most crucial phases concrete conditioning as it determines not only long-term strength, but also influences durability. compounds are useful for reducing evaporation rate water from surface. They typically sprayed on soon possible after consolidation, especially members that have large areas exposed to environment. These been proven work well, however, how effective differe...

Effect of ZnO nanoparticles on nanocomposite coatings based R4152 and graphene oxide (GO) was studied.In presence 2%wt. nanoparticle, abrasion resistance coating increased by nearly 25% (from 75 to 92.9 L/mil) temperature decomposition raised 18oC. SEM images showed that nano can disperse homogenously in polymer matrix GO. Hence, photocatalytic activity R4152/GO/ZnO higher than R4152/ZnO coatin...

there are numerous problems for using essential oil due to its low solubility in water, high vapor pressure and chemical and physical instability. use of nano-emulsions is a good idea for decreasing side effect of the essential oils and enhance their efficiency as well as delivery to hot spot. in addition, nano-emulsion system make smaller size particles and increase stability and shelf-life of...

Colloidal microspheres could be used as raw materials to construct the photonic crystal modification layers on wood surfaces, and would produce gorgeous structural color effect. The diameter, monodispersity self-assembly of colloidal directly affect well-structure order crystals. Therefore, poly(styrene-acrylic acid) (P(St-AA)) shell-core were prepared by emulsion polymerization. effects reacti...

This paper deals with the development of acrylic latexes providing high-performance water-resistant coatings. For this purpose, mutual effects anionic surfactant type (ordinary and polymerizable), covalent intra- and/or interparticle crosslinking (introduced by allyl methacrylate copolymerization keto-hydrazide reaction, respectively) ionic (provided nanostructured ZnO additive) were investigat...
