Metal Organo-Clays as potential adsorbents for hydrogen storage

Azzouz A., Nousir S., Bouazizi N., Roy R., University of Quebec at Montreal, CA

Metal-Organo-Clays (MOC) are novel microporous matrices that can be synthesized via the in-situ formation of Cu, Fe or Pd nanoparticles in montmorillonite-supported polyol dendrimers. This is a new concept that has scarcely been tackled so [...]

Fabrication and Testing of a Miniaturised Water Quality Monitoring pH and Conductivity Sensors

Banna M.H., Najjaran H., Sadiq R., Rodriguez M.J., Imran S.A., Hoorfar M., University of British Columbia, CA

Development of cost-effective, durable and sensitive on-line water quality monitoring sensors that can be installed across the water distribution network has attracted attentions to increase the frequency of monitoring and hence reduce the risk of [...]

Molecular Hydrogen Storage in Fullerenes for Use on Board Fuel Cell Vehicles – A Density Functional Theory Study

Durbin D.J., Allan N.L., Malardier-Jugroot C., Royal Military College, CA

Hydrogen gas is a potential fuel to replace gasoline on board vehicles. However, viable storage methods must be developed. Carbon nanomaterials are promising because they are cheap, lightweight and abundant but carbon-hydrogen physisorption is weak [...]

Fabrication of Infrared Energy Harvester Using Electrically Small Particles

AlShareef M.R., Cui B., Ramahi O., University of Waterloo, CA

A novel structure based on electrically small resonators is proposed for harvesting the infrared energy and yielding more than 84% harvesting efficiency. The proposed harvester has been fabricated using nano-fabrication tools. Moreover, silver adhesion improvement [...]

Simulation and synthesis of a self-assembling and tumor-targeted drug delivery system

McTaggart M., Li X., Malardier-Jugroot C., Royal Military College of Canada, CA

Poly(styrene-alt-maleic anhydride) is an amphiphilic alternating copolymer that self-assembles into supramolecular nanotubes in aqueous, physiological-pH environments. Its 2nm hydrophobic inner diameter is stable in neutral pH solution but opens as pH drops. Folate-conjugated nanotubes could [...]

Nano-Power Implantable Autonomous Closed-Loop CMOS Nerve-Growth-Factor Delivery Microsystem for Neurological Disorders Personalized Therapy

Poustinchi M., Musallam S., McGill University, Neural Prosthetics Laboratory, CA

480 million patients around the globe suffer from neurological disorders which are the fastest-growing disease worldwide. Many neurological and psychiatric conditions are the result of abnormal neurotransmitter concentrations in the brain. Our ultimate goal is [...]

Multimodal Nano-Brain-Machine-Interface for Parallel Electrochemical NeuroSignal Sensing

Poustinchi M., Stacey G., Musallam S., McGill University, Neural Prosthetics Laboratory, CA

Thanks to technological advancements in recent decades, outstanding progress has been made in the field of neuroscience and neural engineering. Although the information processing in the brain is mostly done through neuron’s electrical activities, there [...]

Pore wall charge patterning and spatial profiles of electrical conductivity in short nanopores

Tajparast M., Glavinovic M.I., McGill University, CA

Artificial nanopores are now used as filters, nanofluidic switches or biosensors. Given that their functioning often critically depends on pore conductivity it is important to determine what influences the pore conductivity and how far these [...]

Droplet actuation on a digital microfluidic chip using a 5 volt battery

Rezaei Nejad H., University of British Columbia, CA

This paper presents a circuit using a 5-volt DC battery to actuate droplets on a DMF chip. The output of the circuit is a controllable high voltage, high frequency AC signal which can actuate a [...]
