CdSe Nanoparticles in Silica Matrix by Sol Gel method

Hullavarad N., Hullavarad S., Hullavarad N., Hullavarad S., University of Alaska Fairbanks, US

‘Quantum dots’ or nanoparticles of diverse semiconductor materials are extensively studied because of their interesting size dependent properties. It is further interesting to organize the quantum dots in the form of superlattices thin films, monolithics, [...]

Comparative Analysis for Pseudoboehmite Obtainded by Sol Gel Using Green Chemistry Expert System Sofware

Serna Saiz J., Camargo G., Moreno J.C., Suarez A.F., Universidad Libre, CO

Monohidróxide aluminum, known as pseudoboehmite (AlOOH) was obtained by the sol-gel method by the reaction between aluminum and isopropyl alcohol to produce aluminum isopropoxide using mercuric iodide and Iodine sublimed as catalyst. This work looks [...]

An Improved Micro Injection Molding Technique for Grating Devices

Li H.S., Liu K.C., Hsieh W.H., Au L.K.C., Liu K.C., National Chung Cheng University, TW

There is a new method about grating fabrication in our submission abstract. This method can help us to fabricate micro or nano devices more easily and inexpensively. I think it is very suitable for this [...]

Photocatalytic Activity of Coated PET Fabrics with Synthesised Nano TiO2

Elahi A., Khajavi R., Torkian L., Textile Engineering, IR

Different concentration of TiO2 sols (10-40% g/l) synthesized by titanium tetra isopropoxide (TTIP). PET fabric dipped in prepared sols and sol-gel process accomplished at low temperature. Particle size of synthesised Nano TiO2 determined by particle [...]

Photo Catalytic Activity of Coated PET Fabrics with Synthesised Nano TiO2 & ZnO: A Comparative Study

Elahi A., Torkian L., Khajavi R., Azad University-Tehran South Branch, IR

The coated PET fabric with atomic ratios of Ti/(Ti+Zn) of 100%, 75%, 50%, 25%, and 0% was successfully prepared via sol–gel process from directly mixing TiO2/ZnO sol. The scanning electron microscopy (SEM) observation, energy dispersive [...]

The morphology and properties of silica nanoparticles synthesized by sol-gel reaction in elastomer matrix

Lipinska M., Zaborski M., Technical University of Lodz, PL

In our studies the influence of different dispersing agents on the synthesis and character of silica particles prepared by a sol-gel reaction was investigated. The silica with different surface morphology was synthesized from tetraethoxysilane (TEOS) [...]

Alkoxide-based precursors for direct drawing of metal oxide micro- and nanofibres
