Experiments were performed to study the flow characteristics of ethanol and methanol flow in rectangular micro-channels using test models 1 and 2 (TM1, TM2). The TM1 and TM2 used were of 47 and 50 micro-channels in rectangular crosssection of equivalent diameters of 387 and 327 m respectively. The channel length of 192 mm were fabricated on a 304 stainless steel substrate (230 mm x 160 mm x 1....

Steam reforming integrated with oxidation of methanol was considered with numerical simulation. The parallel micro-channels with circular cross sections were used. Because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. Hence, the approximation of a cylindrical channel is appropriate. Effect of this changing in cross section was considered and results ...

A high sensitive CMOS Micro-electro-mechanical rectangular capacitive pressure sensor in SiGeMEMS process (Silicon Germanium Micro-electro-mechanical System process) is designed and analyzed. Polycrystalline Silicon Germanium (Poly-SiGe) having low fatigue and high strength is effectively used as the sensor diaphragm material to achieve better reliability. The designed perforated diaphragm clam...

The rapid growth in the use of Micro/Nano products in variety of industries such as Micro electromechanical systems (MEMS), microelectronics, Biomedical/Bio-MEMS, automotive (motion sensors), telecommunications etc, has demanded new micro manufacturing methods. The challenge with the manufacturing of Microfluidic devices/biochips is that they often make use of broad range of materials within a ...

We extended the analysis of the thermal conductivity measurements of helium confined in cylindrical channels of glass capillary arrays to the case of rectangular channels. Measurements were made on plates with channels of 1x10 micro-m cross section, and simultaneously on bulk helium. To our great surprise the results show that the finite-size scaling-function for this geometry does not differ m...

In this paper we have analysed and designed a rectangular microstrip antenna. We analyzed micro strip antenna in IE3D by finite moment of method. In this paper we have compare and analyzed the micro strip antenna in infinite ground plane having dimension length, L = 700mil & width, W=800mil to the micro strip antenna in finite ground plane having dimension length, L = 1468mil & width, W=1568mil...

Miniaturization encourages the development of new manufacturing processes capable of fabricating features, like micro-channels, in order to use them for different applications, such as in fuel cells, heat exchangers, microfluidic devices and micro-electromechanical systems (MEMS). Many studies have been conducted on heat and fluid transfer in micro-channels, and they appeared significantly devi...

Various micropatterns have been fabricated and used to regulate cell adhesion, morphology and function. Micropatterns created by standard photolithography process are usually rectangular channels with sharp corners (microgrooves) which provide limited control over cells and are not favorable for cell-cell interaction and communication. This paper proposes a new micropattern with smooth wavy sur...

A circuit is described that has applications for micro scale capacitance tomography. The circuit has been developed for use with linear arrays of rectangular electrodes measuring between 10μm-100μm and integrated onto a silicon chip. Simulations suggest that the circuit is capable of measuring very small capacitance changes of the order of tens of atto-farads. The circuit also features a small ...
