poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (pbgha) and poly (lactide-co-glycolide)/ bioactive glass (pbg) nanocomposite coatings with bone. materials and methods: sol-gel derived 58s bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite nanoparticles were used to prepare the coatings. the nanocomposite coatings were characterized by ...

background : in this study, we investigated the lethal potency, electrophoretic protein pattern and in vivo effects of hottentotta saulcyi scorpion venom in mice. methods : scorpions were collected at night, by using a uv lamp from mardin province, turkey. venom was obtained from mature h. saulcyi scorpions by electrical stimulation of the telson. the lethality of the venom was determined by i....

In this article a method is described to prepare composite colloidal nanoparticles, consisting of a magnetic core (carbonyl iron) and a biodegradable polymeric shell [poly(butylcyanoacrylate) or PBCA]. The method is based on the so-called anionic polymerization procedure, often used in the synthesis of poly(alkylcyanoacrylate) nanospheres designed for drug delivery. Interest of this investigati...

The main objective of this study was to prepare sustained release metformin hydrochloride microcapsules by the Wurster fluidized bed and to obtain the optimized coating process and formulation. Fine microcapsules without agglomeration were obtained in a continuous coating process with the atomization air pressure of 0.2Mpa and an appropriate coating speed temperature. With other design variable...

In this work, the electrokinetic response of nanoparticles suspensions under action alternating electric fields is analyzed for case that particles are coated with a shell polyelectrolyte. This an important field application colloidal systems, as coating necessary or even unavoidable control stability functionalization specific use. Characterization in situ not easy task, and electrokinetics ca...

Aluminum alloy 5052 (Al 5052) is one of the metals used as a bipolar plate in Proton Exchange Membrane Fuel Cell (PEMFC) due to has its light mass and being easy form, and, high conductivity resistivity properties. This material prone corrosion current knowledge protect surface currently lacking. The product PEMFC produces electrical energy, hot steam (313 – 353 K), water. These conditions have...
