in this work, the effect of presence of the sodium tripolyphosphate (stpp), as an inorganic salt, on improving the performance of polyamide (pa) thin layer membranes has been studied. characterization analyses confirmed the presence of the salt on the whole surface structure of the thin layer. different salt loadings resulted in different fluxes and cu (ii) rejections. the thin layer containing...

Duck eggshells are one of bio-wastes from poultry industry and household that have been disposed. contain high calcium which can be applied as an alternative source daily for the body. Nanostructured duck eggshell used a food additive in beef sausage processing. This study was conducted to determine chemical quality fortified by nano-calcium. The materials include beef, soy protein isolate, pal...

Chitosan, a natural biodegradable polymer is recommended for development of nanoparticles intended for chronic infection such as tuberculosis. Formulation and processing variables play a critical role in the formation of nanoparticles prepared with chitosan. The present study investigated the influence of polymer (chitosan) molecular weight, stabilizing agent (tween 80) concentration and stirri...

In order to achieve prolong corneal contact time of norfloxacin (NFX) for treatment of extra ocular diseases, a pH triggered nanoparticulate in-situ gelling system was designed to explore dual advantage of nanoparticles and in-situ gelling system, for its ocular delivery. NFX loaded nanocarriers were developed by ionotropic gelation technique using chitosan as a matrix forming polymer, cross-li...

In this study, a chitosan substrate was modified by simulated body fluid (SBF) treatment, in which the effect of the chosen crosslinking agent was investigated. Two crosslinking agents, glutaraldehyde (GA) and sodium tripolyphosphate (TPP), were used before the SBF process. By using TPP as the crosslinking agent, the Ca/P ratio and the degree of crystallinity were very close to the natural bone...

manganese zinc ferrite nanoparticles (mzf nps) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. to improve the colloidal stability of mzf nps for biomedical applications, nps were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (tpp) as crosslinker. the synthesized nps were characterized by x ray diffraction (xrd) analy...

Macroor micro-porous chitosan membranes have been utilized as adsorptive membrane for the removal of metal ions, organic macromolecules or bioseparation of protein mixtures. The removal or separation mechanism is not based on physical size retention but based on the high adsorption capability of chitosan to the target solutes. For this purpose, it is important that large macro or micro pores an...

Slip casting is a ceramic processing technique which can be used to produce complex-shape object. In the present work, slip was applied 70 mm × 10 15 green samples from recycled soda-lime glass. The with 60% solid loading prepared 100 g of cullet, 1 sodium silicate as binder, 50 ml DI water, and 16.7 deflocculant. deflocculant for 0.1 wt% tripolyphosphate solution. After casting, were dried at ...
