[1]University of Michigan, Ann Arbor, MI, USA
[2]Sandia National Laboratories, Albuquerque, NM, USA

We present a 3D port sweep method in a lossy silicon photonic crystal resonator to demonstrate the capabilities of COMSOL Multiphysics® for frequency domain analysis with input and output ports. This method benefits from the advantages of the S-parameter analysis to characterize the ... Read More

Fast Biofluid Transport of High Conductive Liquids Using AC Electrothermal Phenomenon, A Study on Substrate Characteristics

A. Salari[1], C. Dalton[1]
[1]University of Calgary, Calgary, AB, Canada

AC electrothermal (ACET) micropumps are based on the temperature gradient caused by Joule heating or an external heat source in the bulk of an electrolyte. In this paper, a 2D simulation was performed to study the effect of substrate thickness and material (glass and silicon) for an ACET ... Read More

Development of Magnetic Field Components for the Polarisation Option of the Neutron Spectrometer FOCUS

L. Holitzner[1], U. Filges[1], J.P. Embs[2], T. Fennell[2], T. Panzner[1]
[1]Laboratory for Developments and Methods, Paul Scherrer Institut, Villigen, Switzerland
[3]Laboratory for Neutron Scattering, Paul Scherrer Institut, Villigen, Switzerland

We show a new, favourable space-saving method to host a neutron polarizer in the iron-containing monochromator shielding of a time-of-flight spectrometer for cold neutrons. In this poster you can learn e.g., how to create a robust, homogeneous, rectangular magnetic field (here realized ... Read More

The Effect of Electrochemical Micro-Milling by Rotating Magnetic Field

Modeling of Limestone Calcination Using Joule Heating

R. Kancharla, and M. Ramakrishna
Padmasri Dr. B.V.Raju Institute of Technology
Narsapur
Medak Dist, AP, India

The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO2 in the gas above the solid surface is less than the decomposition pressure of the CaCO3. As the reaction is endothermic, the conventional process for calcination uses coal firing in ... Read More
