Modeling of Microcantilever based Nuclear Microbatteries

Sheeparamatti B.G., Sheeparamatti R.B., Kadadevarmath J.S., Sheeparamatti B.G., Sheeparamatti R.B., Basaveshwar Engineering College, IN

Microcantilevers are extremely versatile and are used as sensors, actuators and in many other microsystems. In this work, mathematical model of a microcantilever based actuator, which can be driven by nuclear radiation, is developed. This [...]

Multi-scale Drug Release Modeling for Targeted Oral Drug Delivery (TODD)

Haddish B.N., Nyquist C., Haghighi K., Wu H.A., Corvalan C., Rickus J., Keshavarzian A., Purdue University, US

Conventional oral dosage forms deliver their active ingredient at rates that are high initially and decline afterward, showing a first order kinetics with the release determining step considered as the dissolution rate of the active [...]

Mathematical Modeling of Water Management in PEM Fuel Cells

Berg P., Promislow K., Stockie J., Wetton B., Simon Fraser University, CA

Liquid water is fundamental to Polymer Electrolyte Membrane fuel cells (PEMFC). Its influence, both beneficial and parasitic, is measured on time scales from femto-seconds to hours, on length scales from Angstroms to centimeters. Its role [...]

Quantum mechanical effects correction models for inversion charge and I-V characteristics of the MOSFET device

Abebe H., Cumberbatch E., MOSIS, US

A 1-dimensional analytic quantum mechanical effects correction formula for the MOSFET inversion charge and I-V characteristics are derived from the density gradient (DG) model using matched asymptotic expansion techniques. The primary theoretical framework for this [...]

Accurate Analytical Models of Fluid Friction in Rectangular Microchannels

Tchikanda S.W., Nilson R.H., Griffiths S.K., Sandia National Laboratories, US

Liquid flow in microchannels is important to a number of technologies including cooling of microelectronics by heat pipes and capillary pumped loops as well as capillary wetting of channels in molding processes and in chip-based [...]

Data on the Slip Coefficients

Sharipov F., Universidade Federal do Parana, BR

For mathematical modeling of micro fluidics it is necessary to calculate a rarefied gas ow through micropumps, microvalves and other elements with a high accuracy. Since the size of micro fluidics is close to the [...]
