“…on the properties of sprayed FTO films have been studied to determine the optimal deposition conditions to obtain as high electrical conductivity and optical transparency as possible [24][25][26]. Among the techniques that have been previously employed are: Thermal evaporation [4,9], Sputtering [11][12], Chemical vapour deposition [13][14][15], Sol-gel coating [4,16], Painting [4,17], Spray pyrolysis [4,6,8],Magnetron Sputtering [19], SPEED technique [21,26,38] and Photo chemical vapor deposition [20].Most of the above techniques have produced high quality FTO films. But, there are still few challenges which limit their usage.…”

Influence of water concentration on the properties of fluorine-doped tin oxide (FTO) thin films was systematically studied in this work. Home made SISOM's SPEED techniques and its chemical formulation was employed to grow the FTO on quartz substrate. Water concentration in the precursor solution was varied from 0, 0.5, 1.0 and 1.5 mol %. The structural, optical, and electrical properties of the films were studied under these deposition conditions. The results show that the properties of the films varied significantly with water concentration. Scanning electron microscopy (SEM) revealed FTO films whose grain size and uniformity increases significantly with increase in water concentration. The structure of the films was measured by X-ray diffraction (XRD) measurement. It shows polycrystalline films with (110), (101), (200), (211) and (220) . The average figure of merit, of the FTO film is 1.25. Optimum deposition condition was established after series of experiments and was found to be 1.5% water concentration at 460 o C substrate temperature. The FTO films deposited in this work could be a promising replacement to indium tin oxide (ITO) especially in dyesensitized solar cells.

This paper reviews a clean metals, production technology that utilizes an oxygen-ion-conducting solid oxide membrane (SOM) to directly electrolyze metal oxides dissolved in a non-consumable molten salts. During the SOM electrolysis process, the desired metal such as magnesium, aluminum, silicon, or a rare earth is produced at the cathode while pure oxygen gas evolves at the anode. Compared with current state-of-the-art metal production processes, such as a chloride-based electrolysis process for magnesium production and the Hall-Héroult process for smelting aluminum, the SOM process brings various advantages such as simplified design, lower cost, lower energy use, and zero emissions. It provides a general route for producing various metals and has great potential to replace current metals, production processes. This paper examines the past and present progress of the SOM process, the challenges faced in commercialization, and the directions for future work.

“…The dominant use of stannous oxide is as a precursor in manufacturing of other, typically divalent, tin compounds or salts. Tin (II) Oxide (Stannous Oxide) have typical applications in pigments, electronic ceramics, capacitors, special refractory's, conductive coatings, chemicals and lens polishing [5][6][7][8][9][10][11]. The study of nanocomposites of stannous-cerium oxide is done for the first time.…”

In the present paper, main emphasis is given to synthesize the Stannous-Cerium oxide nanocomposites in nanofilms, nanodots and nanorods by Chemical bath method, Chemical drop method and Chemical rolling Method. These nanocomposite materials are synthesized on a glass substrate at 100 °C temperature. Crystallography investigation of these materials is done by X-ray diffraction (XRD) which reveals that average grain size is 58.9 nm and 62.3 nm for nanofilms and nanodots on glass substrate respectively whereas XRD diffraction for nanorod on glass substrate reveals that material is amorphous in nature.
