A model of a horizontal atmospheric pressure chemical vapor deposition reactor was implemented to aid in the design of a laboratory based one. The model coupled momentum transport, energy transport, and mass transport phenomena to account for reacting fluid flow of a compressible gas in ... En savoir plus
In Eiceman and Karpas’s book Ion Mobility Spectroscopy (2005), they define Ion Mobility Spectroscopy (IMS) as "the principles, methods, and instrumentation for characterizing chemical substances on the basis of velocity of gas-phase ions in an electric field." The production of the ... En savoir plus
Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like ... En savoir plus
In this work, an analysis is presented for a 3-dimensional RF MEMS coil using the COMSOL AC/DC module in conjunction with the CAD import module. The realization of being able to produce such 3-dimensional RF coils allows for less surface area to be needed for similar inductor performance ... En savoir plus
Kennedy Space Center is leading research work on lunar O2 generation via electrolytic reduction of regolith. The metal oxide present in regolith is dissociated into oxygen anions and metal cations leading to the generation of gaseous oxygen at the anode and liquid metal at the cathode. ... En savoir plus
Heat produced during the curing of light-activated dental restorations could damage the dental pulp. Given the prevalence of composite restorations and the importance of avoiding injury to the pulp, efforts should be made to minimize the temperature increase that occurs at the pulp ...

The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper ...

The need for fast, easy and cost-effective analysis of blood samples as well as our understanding of the functionality of cells and neurons are two rather pressing issues in the modern world. Both of these can be addressed by functional lab-on-a-chip systems, which have been designed and ... En savoir plus
Mass transport modelling through porous media is typically characterized by complex physics and geometry. In the particular case of radionuclide transport, modelling for radioactive waste repositories, an additional level of complexity, and thus uncertainty, originates from the long time ...

Superconducting GHz electronics circuits are frequently used in Radio Astronomy instrumentation. The features of these instrumentations can be significantly improved by using tuneable capacitances, which can be realized by electrically actuated, micromechanical bridges (MEMS) made of ...
