Near-surface tectonic and geomorphic processes involve cooling of rocks through low temperatures (50^2003C). Because rates of helium diffusion in apatite, titanite, and zircon are sensitive to temperature variations in this range, uranium^thorium/helium thermochronometry ((U^Th)/He dating) is well-suited to establishing the timing and rates of these processes in the geologic record. However, be...

The design of crystallization processes becomes more complicated when mixing affects the final crystal product quality (e.g., crystal size distribution and polymorphic form). Such mixing effects are more apparent in antisolvent and reactive crystallizations, which involve the blending of different fluids, and in large-scale crystallizers, where homogeneity cannot be easily achieved. In this pap...

With our recently developed deformation device, the in situ tensile tests of single crystal molybdenum nanowires with various size and aspect ratio were conducted inside a transmission electron microscope (TEM). We report an unusual ambient temperature (close to room temperature) super-plastic elongation above 127% on single crystal body-centred cubic (bcc) molybdenum nanowires with an optimize...

: optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (pr) crystal are investigated. each crystal can be supported the spatial soliton, and at least one must be photovoltaic. the two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...

The deficiency in existing sugar cane crystallization automatic control system is difficult to measure some key parameters on line, such as mother liquor supersaturation, mother liquor purity, crystal content and crystal size distribution. Controlling brix with PID can only reflect the massecuite concentration of sugar cane crystallization process, but it is hard to guarantee the crystal qualit...

Bi2Mn2O7 nano-powders were synthesized via a stoichiometric 1:1 Bi:Mn molar ratio hydrothermal method at 180 °C for 48 h in a 1M NaOH aqueous solution; and solid state method, using Bi(NO3)3.5H2O and MnO2 as raw materials. The synthesized materials were characterized by powder X-ray diffraction (PXRD) technique. Also, the rietveld analysis was done in FullProf in profile matching mode. It was f...

The test parameters were selected as a direct result of a previous study.1 That work involved five Liquid Crystal Display (LCD) projectors and two projectors based on Digital Light ProcessingTM technology. The sample size for this test was increased to seven LCD projectors and nine DLPTM projectors. Like the previous work, this study was supported by Texas Instruments Incorporated (TI). TI pers...

Triple molybdate NaCaLa(1-x-y)(MoO4)3:xEr3+,yYb3+ (x = y = 0, x = 0.05 and y = 0.45, x = 0.1 and y = 0.2, x = 0.2 and y = 0) phosphors were successfully synthesized for the first time by the microwave sol-gel method. Well-crystallized particles formed after heat treatment at 900 °C for 16 h showed a fine and homogeneous morphology with particle sizes of 2-3 μm. The structures were refined by th...

Prediction of supersolubility and the width of the metastable zone has been a major concern among the workers in the field of industrial crystallization. Operation of crystallizers under the optimum supersaturation low enough to attain the desired product quality (Median Particle Size, Crystal Size Distribution (CSD), Shape, Purity) being one motif. The inherent relationship between the sub...

Cobalt ferrite or CoFe2O4 has unique physical and magnetic properties depend on its synthesis method. The application of cobalt ferrite as nanomedicine material become more interesting, however analysis on physical and magnetic properties based on synthesis method have not been discussed. The cobalt ferrite in this research was synthesised using two different methods: the ...
