Nano-encapsulated phase change suspension is a novel type of functional fluid in which the nanoparticles undergo that contribute to heat transfer. Thus, working carries not only by sensible but also form latent stored particles. The natural convection and transfer Nano-Encapsulated Phase Change Materials (NEPCMs) suspensions within boundary layer along heated flat surface are theoretically inve...

Nano-/microparticles of gallium (Ga), as a low-melting-point metal, are extensively used in the fields soft electronics and sensors to provide thermal electrical conductivity. However, passivating oxide layer can be formed on surface Ga nano-/microparticles during synthesis process. This is removed by secondary sintering step, especially mechanical sintering, which generally not controllable pr...

The probiotic industry faces the challenge of retention of probiotic culture viability as numbers of these cells within their products inevitably decrease over time. In order to retain probiotic viability levels above the therapeutic minimum over the duration of the product's shelf life, various methods have been employed, among which encapsulation has received much interest. In line with explo...

during last two decades, polysaccharides such as alginate (alg) alone and in combination with other biopolymers are widely used in vaccine and drug delivery systems. the aim of the present work was to investigate the potential utility of microparticles made of alginate (alg) as new vehicles for improving nasal vaccine delivery. for this purpose, diphtheria toxoid (dt) was chosen as a model anti...

Here we report a novel approach for preparation of a 6-day transdermal drug delivery system (TDDS) as treatment for mild to moderate Alzheimer’s disease. The spray drying method was used to prepare microparticles containing the anti-Alzheimer drug. The content of the drug was determined by High Performance Liquid Chromatography (HPLC) method. The morphology and size range of the microparticles ...
