Technical and Economical Feasibility of Pyrolysis of Kraft Lignin

Farag S., Chaouki J., École Polytechnique de Montréal, CA

This research project discusses the technical and economical feasibility of converting kraft lignin to value-added chemicals. Two pyrolysis techniques were implemented: conventional pyrolysis using classical heating and microwave pyrolysis using electromagnetic irradiation. The product distribution [...]

3D Printing of Double Ka Band Helical Antenna

Lanouette A.-M., Hill J., Dussault P.D., Laurin J.-J., Therriault D., École Polytechnique de Montréal, CA

We present a rapid and low-cost fabrication technique to build a small array of antennas operating in the Ka band (20-30GHz). The designed antenna prototypes have a wire diameter of 0.2mm, a helix diameter of [...]

Dual Helix Dielectrophoretic Cell Separator Fabricated Using the Direct-Write Spindle Deposition Technique

Guérin N., Lévesque M., Therriault D., École Polytechnique de Montréal, CA

Many biomedical procedures necessitating the separation of cells would benefit from the miniaturization of cell separators. This miniaturization effort has led to the development of 2D dielectrophoretic separators. The use of a 3D dielectrophoretic cell [...]

Scalable gas phase nanoparticle treatment methods required for large-scale nanofluid and nanocomposite synthesis

Dion C.A.D., Tavares J.R., École Polytechnique de Montréal, CA

Recent work has demonstrated that while nanofluids do indeed exhibit increased heat transfer properties , there is no abnormal enhancement as had been claimed by early proponents of nanofluids. However, this lack of abnormal enhancement [...]

Plasmonic nanostructure based biosensing

Patskovsky S., École Polytechnique de Montréal, CA

Plasmonics is quickly becoming a dominant technology in the fields of novel optical devices employing new experimental capabilities of subwavelength metallic nanostructures. In combination with modern nanofabrication technologies which allows preparation of numerous regular patterns [...]

Programmable Three-Dimensional Microfluidic Fabrication by Direct-Write Assembly

Ghafar-Zadeh E., Therriault D., Sawan M., École Polytechnique de Montréal, CA

There are increasing needs for 3D microfluidic components such as microchannels, micromixers or micropumps for Laboratory-on-chip systems. To date, several efficient, but expensive and complex techniques such as Liga and micro-stereo-lithography [1] have been developed [...]

Direct-Write CMOS-Based Laboratory-On-Chip

Ghafar-Zadeh E., Sawan M., Therriault D., École Polytechnique de Montréal, CA

Over the recent years, the identification of genes which influence many diseases has been highly demanded and now, molecular diagnosis is most promising technology to offer fast and early detection of diseases to a maximum [...]
