Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), ... En savoir plus
In this work, the theoretical study for the realization of waveguiding layer acoustic waves devices based on AlN/IDT/ZnO/Silicon structure using the modeling software COMSOL Multiphysics (2D) is presented. The effect of thicknesses of AlN and ZnO thin films on the evolution of frequency ... En savoir plus
Adulteration of automobile fuels, especially petrol and diesel is a rampant malpractice in India. With the rising prices of fuel and the subsidy on kerosene, getting away with even 10-15% adulteration is immensely profitable.To check adulteration effectively, it is necessary to monitor ...

This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric ... En savoir plus
Transducer optimization is a key aspect for successful development and deployment of advanced sensors, especially when designing 3D structures for harsh environments. For piezoelectric transducers, plate thickness determines the operating frequency of the resonator, which is frequently ... En savoir plus
In this research, we performed multiple COMSOL Multiphysics® simulations. We analyzed the dispersion curves of waves in a LAMB wave pressure sensor; simulated a thin metal film in a microbolometer and observed the resulting stress; investigated the thermal behavior of an acoustic wave ...

Microgrippers are typical MEMS devices used to pick, hold and transport micro-objects. Microgrippers are widely used in the field of micro-assembly, micro-surgery and manipulation of micro-particles. Thermal microgrippers are widely used for large displacement, high accuracy and ... En savoir plus
In this paper, implicit Large Eddy Simulation (LES) based on finite-element analysis is performed in order to investigate two-dimensional circular cylinder incompressible flow. Implicit LES attempts time-dependent flow computation with no explicit turbulence model. Here, two types of ... En savoir plus
INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... En savoir plus
