3D model of MEMS based SAW gas sensor is designed using Focused Inter Digital Transducers design. Surface displacement & Electrical potential are analyzed at resonance & anti-resonance frequencies. Operating frequency is from 8.7 MHz which acts as start band and 9.2 MHz as stop ... En savoir plus
The objective of this paper is to design a 3D Gas Sensor for sensing Hydrogen gas and to increase the conductivity at nano level. In this novel design, nanorods act as the sensing layer. The sensitivity towards gas adsorption is found to be increased due to its high surface to volume ... En savoir plus
: One of the most commonly used techniques for quantification of beating forces exerted by cardiomyocytes is culturing them on a bed of vertical microcantilevers or microposts. The position of the microcantilevers is observed through advanced imaging techniques and the displacements are ... En savoir plus
Microfluidic devices and lab-on-a-chip (LOC) require the ability to transport or pump reagents or reaction products, the ability to effectively mix small volumes of fluid, and provide direct data display. Surface acoustic wave (SAW) driven acoustic streaming generated by a piezoelectric ... En savoir plus
The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by ... En savoir plus
Chemical vapor deposition is considered a promising method for synthesis of graphene films on different types of substrate utilizing transition metals such as Ni. However, synthesizing a single-layer graphene and controlling the quality of the graphene CVD film on Ni are very ... En savoir plus
A numerical simulation study, using COMSOL Multiphysics®, was carried out to examine the temperature and concentration fields in the dissolution process of silicon into germanium melt. This work utilized a simplified configuration which may be considered to be similar material ... En savoir plus
Recently, increasing availability of natural gas, due to the shale gas, raises the attention to the conversion of methane. Methanol-to-Hydrocarbons reaction (MTH) plays an important role in this route where methanol synthesized through syngas is converted into hydrocarbons, such as ... En savoir plus
This paper is a preliminary design study to develop a hybrid atmospheric icing sensor which have an adequate potential to detect an icing event, icing type and icing rate together with icing load. The physics to detect icing event and icing type have been numerically understood using ... En savoir plus
The primary function of the vestibular system is to provide the brain with information about the body\'s motion and orientation. The absence of this information causes blurred vision and spatial disorientation, vertigo, dizziness, imbalance, nausea, vomiting, and other symptoms often ... En savoir plus
