Residue particles with volume median diameters ranging from 23 to 68 nm were made by dispersing KNO3 or MnCL2.4H2O solutions with commercially available pneumatic nozzles at liquid flow rates of 0.07 and 0.021 cm3/s and atomizing air pressures (gauge) ranging from 276 to 3447 kPag. Droplets with median diameters of 1.5 +/- 0.03-mu-m were made at the 0.07 cm3/s liquid flow rate, which represents a nearly 10-fold increase in liquid flow rate achieved with Collison atomizers used to generate droplets of similar sizes under conditions specified by their manufacturers.


Device Characterization of ZnInSe2 Thin Films
Gullu, H. H.; Parlak, Mehmet (Elsevier BV; 2016-01-01)
p-Si/n-ZnInSe2 hetero-junction diode was deposited by thermal evaporation of elemental evaporation sources on the 600 mu m thick p-type (1 1 1) mono-crystalline Si wafers having the resistivity value of 1 - 3 (Omega.cm). Detailed electrical characterization of the hetero-junction was performed by the help of temperature dependent current-voltage measurements. The forward current-voltage behaviour of the hetero-junction diode was investigated under the evaluation of possible current transport mechanisms. In ...
Streamwise oscillations of a cylinder beneath a free surface: Free surface effects on vortex formation modes
Bozkaya, Canan; Mironova, L. A.; Gubanov, O. I. (Elsevier BV, 2011-06-15)
A computational study of a viscous incompressible two-fluid model with an oscillating cylinder is investigated at a Reynolds number of 200 and at a dimensionless displacement amplitude of A = 0.13 and for the dimensionless forcing cylinder oscillation frequency-to-natural vortex shedding frequency ratios, f/f(0) = 1.5, 2.5, 3.5. Specifically, two-dimensional flow past a circular cylinder subject to forced in-line oscillations beneath a free surface is considered. The method is based on a finite volume discr...
Ultra-fast charge exchange spectroscopy for turbulent ion temperature fluctuation measurements on the DIII-D tokamak (invited)
Uzun Kaymak, İlker Ümit; McKee, G. R. (2012-10-01)
A novel two-channel, high throughput, high efficiency spectrometer system has been developed to measure impurity ion temperature and toroidal velocity fluctuations associated with long-wavelength turbulence and other plasma instabilities. The spectrometer observes the emission of the n = 8-7 hydrogenic transition of C+5 ions (lambda(air) = 529.06 nm) resulting from charge exchange reactions between deuterium heating beams and intrinsic carbon. Novel features include a large, prism-coupled high-dispersion, v...
Mechanism and characterization studies on boron carbides deposited by chemical vapor deposition technique
Karaman, Mustafa; Özbelge, Hilmi Önder; Sezgi, Naime Aslı; Doğu, Timur (2005-12-02)
Boron carbide was produced in an impinging jet CVD reactor from a gas mixture of BCl3, CH4 and H-2. The mass transfer limitations on the reaction kinetics were minimised by the jet impingement on the substrate surface. XPS characterization of the produced deposits revealed a nearly pure boron carbide phase containing small amounts of oxy-boron and oxy-carbon species. After a detailed kinetic study, a reaction model was proposed to predict the rates of boron carbide and dichloroborane formation reactions. In...
Thermal characterization of crude oils by pressurized differential scanning calorimeter (PDSC)
Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2019-06-01)
In this research, pressurized differential scanning calorimeter (PDSC) were used to estimate the thermal and kinetic behaviour of two different crude oils from Tatarstan oil fields under three different pressures (100, 600, 2000 kPa) at a constant heating rate (10 degrees C/min). The heat flow curves of both crude oils indicated two reaction regions known as low temperature oxidation (LTO) and high temperature oxidation (HTO). The reaction intervals were shifted to lower temperature regions with the increas...
