Mateo Villanueva, Pedro Abdiel

Water management on proton exchange membrane fuel cells is one of the biggest issues that stop the effective commercialization of this promising technology. Due to water flooding, the performance of fuel cells decays rapidly at high current densities. To better design fuel cell electrodes, a...

Breton, Kevin M

This study used non-intrusive, optical based measurement techniques in a parametric study of a flash atomized jet. The bench scale water spray was operated at pressure ratios ranging from 6.80-17.0 and degrees of superheat of 20-80 °C. This broad range of parameters allowed for the evaluation of...

An experimental study was conducted to assess the scratching abrasion in dry and wet environments on X-70 steel and five different types of titanium carbide particulate polyurethane composites (PU). A testing apparatus was constructed based on the dry sand rubber wheel test method standardized by...

The continuing interest in Lab-on-a-Chip technologies and Point-of-Care diagnostics systems is driving the development of supporting components for microfluidic regulation. Optimally the microfluidic regulation components would operate cyclically with a minimum input power, could be precisely...

Many real-world facility location problems can be approximated by a grid-based system of small sized cells, which can then be used to model a heterogeneous demand distribution. We can also relate an amount of supply for each cell from its supply distribution relationships with the various...

Rapid characterization of complex fluids, especially sensing emulsion stability, is crucial for many industrial applications, ranging from pharmaceutical industry to petroleum production. Electrochemical impedance spectroscopy (EIS) is a powerful tool for electrical characterization of such...

Kirk, Alistair S.

In the development of a numerical model for the water cycle on Mars, adsorption of water vapour in the Martian regolith acts as a significant sink and retards the transport of mass. Adsorption on Mars cannot be studied directly, so a numerical model was created, and a diffusion sorption...

Gharib, Hossam M.H.

This work involves the design, microfabrication, calibration, and testing of a new silicon-based piezoresistive rosette capable of extracting the three-dimensional (3D) stresses in the silicon upon deformation. A new 10-element piezoresistive rosette was devised to extract all stress components...

Open-cathode polymer electrolyte fuel cell (PEFC) stacks use hydrogen as a fuel, are a high efficiency power source, and do not produce CO2, NOx, SOx, or particulate matter. When used as a remote power source, the PEFC stack must be protected from adverse environmental conditions. To provide...

Milne, Andrew J. B.

For drops sessile on a solid surface, cross flowing air can drive drop oscillation or shedding, based on the balance and interaction of aerodynamic drag force (based on drop size/shape and air speed) and adhesion/capillary forces (based on surface tension and drop size/shape). Better...
