abstractvarious nanoparticles have been investigated as novel drug delivery systems, including solid lipid nanoparticles (slns). due to their rapid clearance from systemic circulation, nanoparticles do not provide sustained action in most cases. different strategies have been employed to overcome this problem. in this direction, the present study introduces erodible in-situ forming gel systems ...

This paper presents experimental analysis and results of GaN (being a III-V semiconductor) doped with Ferrite elements synthesized using Sol-Gel technique which are carried out at National Chemical Laboratory, Pune Maharashtra. The GaN is employed as dopant for x=1 and x=5, in the formula Ga(2x) N Fe2(49-x) O3 . A non-spinel ferrite system ( Fe2 O3) is chosen for our study. The XRD (Structural)...

A series of inorganic pigments containing iron, aluminum, strontium, and silicate were prepared by the sol-gel method using compounds with different structures morphologies as starting materials. The synthesis was carried out modified citrate method. All powders placed in a muffle furnace calcined air at 1100°C for 6 hours. Powder samples Fe, Sr, Al Si oxides obtained. structure chemical compos...

In this study, the synthesis of nano-porous calcium magnesium silicate was performed and studied to improve drug properties and drug release. This synthesis was carried out by using the tetraethyl ortho silicate precursor (TEOS) and the Cetyltrimethyl ammonium bromide surfactant (CTAB) in a sol-gel alkaline environment; and the product was heat treated at 600° C and 800° C temperatures....

A heat-induced O/W emulsion gel that undergoes a phase transition from sol to gel on heating was formed from the addition of aqueous HCl to a toluene solution of a long-chain amidoamine derivative (C18AA). The heat induced O/W emulsions are highly sensitive to temperature, and the sol-gel transition temperature could be simply controlled by adjusting the C18AA concentration. Interestingly, the ...
