In this work, we used a simple and totally green method for synthesizing silver nanoparticles using kappa-carrageenan as reducing and stabilizing agent. The beads were prepared in aqueous medium by microwave heating, and then followed by cross-linking with K+ cations without using any additional toxic and expensive chemical agents. The preparation method of the carrageenan-based beads is easy, ...

Background: Expansion and differentiation of stem cells relies on the soluble materials as well as the physical conditions of their microenvironment. Several methods have been studied in attempt to enhance the growth and differentiation rates of different adult stem cells extracted from different sources. Objectives: The purpose was to improve the three-dimensional (3D) culture condition of th...

This research is a novel experimental work on cooling solar panels using hydrogel beads saturated with Al2O3 water based nanofluid. Nanofluid of concentrations 0.1, 0.25, and 0.5% wt. were used compared to the only cooled uncooled PV panels. A passive system was created three layers nanofluid hydrogels attached back surface exposed panels, fixed radiation intensities 800 1000 W/m2. Using 0.5%wt...

Using ion-exchange resins, a multiple-unit type of oral floating dosage system has been prepared to prolong gastric emptying time of dosage form. The system is composed of beads of drug-resin complex, which are loaded with bicarbonate ions and coated with a hydrophobic polymer. The system is so designed that when the beads reach the stomach, chloride ions are exchanged with bicarbonate and drug...
