Evaluation of effective parameters on fabrication of BSA nanoparticles
Coacervation technique was implemented in fabrication of BSA nanoparticle for the purpose of drug delivery system. Nanoparticle was purified with 48,800 g centrifuge, and then followed by dialysis, micro and ultra filtration. The fabricated nanoparticles were subjected to physical, morphological and biochemical characterization. The analyzed samples by SEM and AFM proved the semi-spherically shape of the particles whilst the size distribution was measured by photon correlation spectroscopy. Fourier transforms infra-red spectroscopy (FTIR) spectrum indicated that the fabricated nanoparticles were pure. The impact of various parameters upon the particle size was extensively investigated. The concentration of glutaraldehyde at fixed temperature had absolutely no significant effect on the size of particles. The affecting parameter was modeled to predict the size of nanoparticle. At low temperature (4{degree sign}C), the nanoparticle size of 89.3nm was fabricated with pure BSA concentration of 20 mg.ml-1

Preparation and characterization of self-Nanoemulsifying drug delivery system (SNEDDS) for oral delivery of curcumin
Introduction: Curcumin is a compound possessing different pharmacological effects which is poorly soluble. Also, bioavailability of curcumin is low. In this study we aimed to improve solubility and bioavailability of curcumin by developing a self-nanoemulsifying drug Delivery system (SNEDDS) for oral delivery of curcumin.
Methods and Results: Box –behnken was used to design optimum run. Several factors such as concentration of solvent, surfactant, and co-solvent were independent while dependent factors include droplet size, PDI (poly dispersity index), and zeta potential. Although, release test and study EE % (Entrapment efficiency) were done and images were taken using a TEM microscope.
Droplet size of optimized formulation SNEDDS was 245.22 nm. PDI and zeta potential were 0 .38 and -1.28 mv, respectively. TEM images showed that the particles were spherical with no sign of aggregation. Also, our results revealed slow release profile.
Conclusions: The obtained results indicated that SNEDDS could be considered as a good candidate for oral delivery of curcumin to improve its solubility and bioavailability as an active ingredient
Development Of Inorganic Membrane To Remove Oil Emulsifier From Domestic Waste water.
The rapid development of membranes in waste water treatment was a great encouragement to participate and fabricate inorganic membrane. The results yielded to an expansion of knowledge and producing various types of ceramic membrane. The ceramic membrane has a great potential and market, ceramic membrane represents a distinct class of inorganic membranes, especially the metallic coated has many industrial application. The porous ceramic was prepared for to fabricate the supported membrane. A thin film of Aluminium and Zirconium were formed. Unsupported membrane was also prepared
