In situ forming intragastric controlled-release formulation is a new technology in the field of oral controlled-release delivery systems. The objective of this study was to develop formulations that can control drug release up to 24 hours. In addition, a combination of appropriate polymers and solvents was selected that could form a drug loaded gel at the process temperature of 60-70 °C, which ...

Perovskite nanocrystals are gaining increased attention because of their magnetic, transport and catalytic properties, particularly there is a renewable interest cobalt perovskites for catalysis. Accordingly, the correct interpretation properties stemming from particular configuration cations within this crystalline structure compulsory. Herein, we report synthesis Nd0.75Sr0.25CoO3 using citrat...

High surface area ceria nanoparticles have been prepared using a citrate sol-gel precipitation method. Changes to the particle size have been made by doping ceria powders, and calcining at different temperatures. Xray methods were used to determine their lattice parameters. The particle sizes have been assessed using transmission electron microscopy (TEM) and the lattice parameter found to fall...

A significant challenge in tissue engineering is the creation of tissues with stratified morphology or embedded microstructures. This study investigated methods to fabricate composite gels from separately deposited alginate layers and examined the effects of processing methods on the mechanics of adhesion. Laminated alginate gels were created through a three step process which included: treatme...

This study aims to obtain insights into the retardation mechanism of citric acid in an ettringite-based binder from ladle slag and gypsum. The hydration kinetics phase assemblage were experimentally investigated thermodynamically modelled. Additionally, effects on synthetic ettringite studied further understanding interaction between this organic ligand crystal. Experimental results reveal that...

During the transformation of chloroplasts to chromoplasts in Capsicum annuum L., the permeability of the envelope membranes to possible precursors of carotenoid biosynthesis (acetate, mevalonate, citrate) was tested. The plastids were isolated by gel filtration, and the uptake of labeled compounds was measured by a filtering centrifugation technique, using silicone oil. The different ripening s...

Alginate based floating in situ gelling systems of famotidine (FIGF) were prepared by dissolving varying concentrations of alginate in deionized water containing sodium citrate, to which varying concentrations of drug and calcium chloride was added and dissolved by stirring. Results of preliminary trials indicate that concentrations of sodium alginate, calcium chloride and sodium citrate affect...
