Bismuth antimony telluride nanopowders were prepared by using mechanochemical method. Three different materials; Bismuth Telluride, (Bi0.75Sb0.25)2Te 3 and (Bi0.5Sb0.5)2Te 3 were synthesized. XRD and TEM analysis was carried out to confirm the results. The particle size of the material was determined by using FESEM analysis. The two alloys of Bismuth Telluride such prepared were converted in the pellet form using vacuum hydraulic pressure and their Seebeck coefficients were determined to test the material suitability for its use as a thermoelectric device. Their power factor measurement and Hall effect measurements were carried out at room temperature. Keywords: Bismuth telluride; Mechanochemical method; energy in one form into another. Use of TE solid materials Applications Nanoparticals; Seebeck coefficients in heat pump and refrigeration is well known [14] and it is now expanded such as cooled seats in luxury automobiles [15]. -

The Corning Willow glass is Room: 211B - Session EN+AS+EM+NS+SE+SS+TF- coated with a molybdenum layer as a reflective back contact layer. By using MoM a single step and a solution deposition method, lower production cost are achievable. For thin film deposition, we used a non-vacuum spin coater (WS650 spin processor, Laurell Technologies) with an optimized spin coat Solar Cells I programming. Annealing took place under vacuum in a RTP furnace while Moderator: Jason Baxter, Drexel University, Chintalapalle time, temperature and ramp functions were varied. The other layers of the Ramana, University of Texas at El Paso device consists of cadmium sulfide n-type window layer and a zinc oxide doped with aluminum transparent top contact layer. Characterization and analysis of the thin films were performed using Raman spectroscopy, 8:20am EN+AS+EM+NS+SE+SS+TF-MoM1 Elevated Temperature scanning election microscope (Zeiss NEON 40), X-ray diffraction (Philipps Phase Stability of CZTS-Se Thin Films for Solar Cells, E.

.. & METEORITIC RUTILE Peter R. Buseck Departments of Geology and Chemistry Arizona State University Tempe, Arizona Klaus Keil Space Sciences Division National Aeronautics and Space Administration Ames Research Center Mof fett Field, California r ABSTRACT Rutile has not been widely recognized as a meteoritic constituent. show, Recent microscopic and electron microprobe studies however, that Ti02 . is a reasonably widespread phase, albeit in minor amounts. X-ray diffraction studies confirm the Ti02 to be rutile. It was observed in the following meteorites - Allegan, Bondoc, Estherville, Farmington, and Vaca Muerta, The rutile is associated primarily with ilmenite and chromite, in some cases as exsolution lamellae. Accepted for publication by American Mineralogist . Rutile, as a meteoritic phase, is not widely known. In their sunanary . of meteorite mineralogy neither Mason (1962) nor Ramdohr (1963) report rutile as a mineral occurring in meteorites, although Ramdohr did describe a similar phase from the Faxmington meteorite in his list of "unidentified minerals," He suggested (correctly) that his "mineral D" dght be rutile. He also ob- served it in several mesosiderites. The mineral was recently mentioned to occur in Vaca Huerta (Fleischer, et al., 1965) and in Odessa (El Goresy, 1965). We have found rutile in the meteorites Allegan, Bondoc, Estherville, Farming- ton, and Vaca Muerta; although nowhere an abundant phase, it appears to be rather widespread. Of the several meteorites in which it was observed, rutile is the most abundant in the Farmington L-group chondrite. There it occurs in fine lamellae in ilmenite. The ilmenite is only sparsely distributed within the . meteorite although wherever it does occur it is in moderately large clusters - up to 0.5 mn in diameter - and it then is usually associated with chromite as well as rutile (Buseck, et al., 1965), Optically, the rutile has a faintly bluish tinge when viewed in reflected, plane-polarized light with immersion objectives. -

Occurrence, Alteration Patterns and Compositional Variation of Perovskite in Kimberlites
975 The Canadian Mineralogist Vol. 38, pp. 975-994 (2000) OCCURRENCE, ALTERATION PATTERNS AND COMPOSITIONAL VARIATION OF PEROVSKITE IN KIMBERLITES ANTON R. CHAKHMOURADIAN§ AND ROGER H. MITCHELL Department of Geology, Lakehead University, 955 Oliver Road, Thunder Bay, Ontario P7B 5E1, Canada ABSTRACT The present work summarizes a detailed investigation of perovskite from a representative collection of kimberlites, including samples from over forty localities worldwide. The most common modes of occurrence of perovskite in archetypal kimberlites are discrete crystals set in a serpentine–calcite mesostasis, and reaction-induced rims on earlier-crystallized oxide minerals (typically ferroan geikielite or magnesian ilmenite). Perovskite precipitates later than macrocrystal spinel (aluminous magnesian chromite), and nearly simultaneously with “reaction” Fe-rich spinel (sensu stricto), and groundmass spinels belonging to the magnesian ulvöspinel – magnetite series. In most cases, perovskite crystallization ceases prior to the resorption of groundmass spinels and formation of the atoll rim. During the final evolutionary stages, perovskite commonly becomes unstable and reacts with a CO2- rich fluid. Alteration of perovskite in kimberlites involves resorption, cation leaching and replacement by late-stage minerals, typically TiO2, ilmenite, titanite and calcite. Replacement reactions are believed to take place at temperatures below 350°C, 2+ P < 2 kbar, and over a wide range of a(Mg ) values. Perovskite from kimberlites approaches the ideal formula CaTiO3, and normally contains less than 7 mol.% of other end-members, primarily lueshite (NaNbO3), loparite (Na0.5Ce0.5TiO3), and CeFeO3. Evolutionary trends exhibited by perovskite from most localities are relatively insignificant and typically involve a decrease in REE and Th contents toward the rim (normal pattern of zonation). -
