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)...

Clearcoats provide long-term aesthetics and protection for underlying coating systems, increasing product lifetimes. However, organic clearcoats are predominantly produced using fossil-fuel feedstocks. In search of a sustainable alternative, an experimental investigation was conducted on the development glass-like sol-gel process. The processing over pigmented polyurethane studied by modifying ...

The extensive research activity on sol-gel processing of silica glass has been reviewed by several authors [l-4]. The typical alkoxide route to silica sols comprises the catalyzed reaction of tetraethoxysilane (TEOS) and water in a mutual solvent. The TEOS alkoxy groups hydrolyze to form silanol monomers which condense and crosslink to form the silica gel network. The nature of the sol and the ...

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 ...

We have fabricated high quality sol-gel derived silicate and aluminoborosilicate thin films deposited on silicon substrates. From capacitance vs voltage measurements we observe low interface trap densities (<10H/cm2eV) and very low densities of slow interface state (<101~ 2) in most films investigated. We have been able to make significant improvements over previous sol-gel derived oxides on si...

The paper describes development of a sol-gel based immunoaffinity method for the steroid hormone levonorgestrel (LNG) and the effects of changes in the sol-gel matrix format on the activity of the entrapped antibodies (Abs) and on matrix structure. The best sol-gel format for Ab entrapment was found to be a tetramethoxysilane (TMOS) based matrix at a TMOS:water ratio of 1:8, containing 10% poly...

Microencapsulation has become a hot topic in chemical research. Technology mainly used for control release and protection purposes. The sol-gel micro encapsulation approach for fragrance and aroma in porous silica-based materials leads to sustainable odorant and flavored materials with novel and unique beneficial properties. Sol-gel encapsulation of silica based micro particles considered econo...
