A possible growth mechanism is proposed using the results of these studies. The texture coefficient values of all the structures, indexed to a tetragonal lattice, exhibit amazing variation in the preferred orientation with respect to their shapes. Although XPS data indicate that wires and cubes have a strong SnO2 type signal, bipyramids interestingly exhibit both SnO and SnO2 signals and a correlation of the binding energy helps in understanding the growth kinetics of such submicron structures. The. results suggest that the bipyramids are formed because of the vapor-solid process (VS) while wires and cubes are formed by the vapor-liquid-solid (VLS) progression.</p>1 aRamgir, N., S.1 aMulla, Imtiaz, S.1 aVijayamohanan, K., P.  uhttps://library.ncl.res.in/content/effect-ruo2-shape-selectivity-submicron-sized-sno2-structures-001412nas a2200217   4500008004100000022001400041245008100055210006900136260006900205300001200274490000800286520066000294653000800954653001400962653000800976653003000984100001901014700002201033700002601055856011301081       2005                        eng d  a0925-400500aRoom temperature nitric oxide sensor actualized from Ru-doped SnO2 nanowires0 aRoom temperature nitric oxide sensor actualized from Rudoped SnO  aPO BOX 564, 1001 LAUSANNE, SWITZERLANDbELSEVIER SCIENCE SAcJUN  a708-7150 v1073 a<p>We report synthesis of the novel Ru-doped SnO2 nanowires and their distinctive response towards NO., and liquefied petroleum gas (LPG) in air. These nanowires have been prepared by a simple approach of evaporation of metal oxide at elevated temperature, The sensor exhibits three order of magnitude changes in the conductivity on exposure to NO2 in air at room temperature, Furthermore. Ru being one of the excellent sensitizers towards LPG these wires also exhibits sensitivity at 250&amp;DEG; C. The amount of Ru plays a crucial role in modulating the sensitivity and lowering the operating temperature. © 2005 Elsevier B.V.
