Raman and TEM studies of Ge nanocrystal formation in SiOx : Ge/SiOx multilayers
(Wiley-V C H Verlag Gmbh, 2007)
Alternating germanosilicate-siliconoxide layers of 10-30 nm thickness were grown on Si substrates by plasma enhanced chemically vapor deposition (PECVD). The compositions of the grown films were determined by X-ray ...
Effect of powder size on infiltration height in producing MgO reinforced Al matrix composite by vacuum infiltration method
(Trans Tech Publications Ltd, 2007)
The vacuum infiltration method is one of the composite producing methods. There are several parameters in composite production by vacuum infiltration. One of them is particle size of reinforcement in particulate reinforced ...
??? Transformation in sialon ceramics
(2002)
A number of different starting compositions, within or just outside the ?-sialon stability region of yttrium sialon system, were prepared using the oxides of rare-earth elements (Nd, Sm, Dy and Yb) as ?-sialon stabilizers. ...
Investigation of brush seal flow characteristics using bulk porous medium approach (Conference Paper)
(2003)
The flow behavior through a brush seal has been investigated by developing a flow analysis procedure with a porous medium approach. In order to increase the brush seal performance and use at more severe operating conditions, ...
Evaluation of brush seal performance for oil sealing applications
(2003)
Oil sealing at high speeds is one of the major problems engineers should address in turbomachinery design. High temperatures faced in oil sumps in aircraft engines, and large seal sizes typical in land based turbine ...
The influence of sevoflurane anesthesia on the rat red blood cell deformability
(2006)
Alterations in blood rheology under the influence of anesthesia have been observed and discussed among the responsible factors for the deterioration of tissue and organ perfusion related to anesthetic procedures. Sevoflurane ...
Finite Element Modeling and Optimization of Tube-Shaped Ultrasonic Motors
(2003)
Recent developments in ultrasonic motor design have demonstrated that small size tube-shaped motors could be fabricated at low cost. Motors with diameters between 15 and 2.5mm have been fabricated and tested. The performance ...
Elasto-Optical Properties of Thin Polymer Films by Prism Coupling Technique
(American Institute of Physics Inc., 2004)
Reliable measurement of stress dependent refractive index of thin polymer films has been achieved. The effect of the applied stress on the refractive index and birefringence of the films was investigated. The out-of-plane ...
Brush seal temperature distribution analysis (Conference Paper)
(2005)
Brush seals are designed to survive transient rotor rubs. Inherent brush seal flexibility reduces frictional heat generation. However, high surface speeds combined with thin rotor sections may result in local hot spots. ...
Studies of Al-Ti alloys by SEM
(2007)
Al-Ti (1, 2 wt. %) alloys were investigated by Scanning Electron Microscopy (SEM). SEM observations and energy-dispersive x-ray analyses (EDX) showed that the phase structure of Al-Ti (1 %) alloy at 165 ?m/s is composed ...
