Conductive cellulose nanocrystals

University of Waterloo

BackgroundIntrinsically conductive polymers (ICPs) refers to organic polymer that has the ability to conduct electricity. (ICPs) have demonstrated their usefulness in a wide variety of applications, such as sensors, anti-static/electromagnetic interference shielding, organic light-emitting diode (OLED), supercapacitors, etc. due to their superior physical and chemical properties.  However, the inherent problems with ICPs such as low solubility, intractable phase, poor mechanical...

Prodrug inhibitors of aminoglycoside acetyltransferases as agents to block resistance to aminoglycoside antibiotics

Université McGill

This technology represents a major change in the way antibiotic resistance to aminoglycosides will be managed and offers an opportunity for rescuing antibiotic activity via the AAC(6’) and APH3’ mechanisms of resistance. We anticipate that the proposed prodrugs, if used in combination with aminoglycoside antibiotics, will represent potential novel drugs to treat infections from resistant strains (both Gram-positives and -negatives). The presence of genes encoding for AAC(6’) and APH3’ in a...

PROCEDE D~ELIMINATION DU CONTAMINANT MERCURE DES SOLUTIONS AQUEUSES ET DES BIOREACTEURS DE CELLES-CI

Université d'Ottawa

Provided herein are methods for removing mercury contaminant from an aqueous solution, the methods including: providing an aqueous solution, the aqueous solution being contaminated with at least trace amounts of an oxidized mercury species; culturing a photoheterotrophic or fermentative heterotrophic bacteria in the aqueous solution under anaerobic conditions in which the bacteria reduce the oxidized mercury species to elemental mercury (Hg0), wherein the bacteria comprises one or more...

CO-TRAITEMENT DE LIQUÉFACTION HYDROTHERMALE DE BOUES D'EAUX USÉES ET DE BIOMASSE LIGNOCELLULOSIQUE PERMETTANT LA COPRODUCTION DE BIO-GAZ ET DE BIO-HUILES

Western University

La présente invention concerne un procédé fondé sur un traitement de liquéfaction hydrothermale (HTL) permettant le co-traitement de boues d'eaux usées et d'autres biomasses lignocellulosiques à haute teneur en eau pour la coproduction de biogaz et de bio-huile brute. Le mélange de boues d'eaux usées activées et de biomasse lignocellulosique telle que la sciure de bois de bouleau/la tige de maïs/les MSW a été converti dans des conditions de HTL en présence de KOH en tant que catalyseur...

PROCEDE DE PREPARATION DE SUBSTANCES CRISTALLINES D'ELECTRODE ET SUBSTANCES OBTENUES PAR CE BIAIS

Clariant (Canada), Polytechnique Montréal, Université de Montréal

There is provided a process for preparing a crystalline electrode material, the process comprising: providing a liquid bath comprising the electrode material in a melted state; and introducing a precursor of the electrode material into the liquid bath, wherein the electrode material comprises lithium, a metal and phosphate. There is also provided a crystalline electrode material, comprising lithium substituted by less than 0.1 atomic of Na or K; Fe and/or Mn, substituted by less than 0.1...

DEGRADATION D'HYDROCARBURES A L'AIDE DE CHAMPIGNONS FILAMENTEUX

University of Saskatchewan

The use of a filamentous fungus for degrading hydrocarbons and environmental toxins is provided. The filamentous fungus can be Trichoderma harzianum strain TSTh20-1.

TRAITEMENT DE PURGE SOUS PRESSION ET FLUX DE RESIDUS MINIERS

KEMIRA OYJ, Suncor Energy, Université de l'Alberta

Techniques for treating by-product and waste streams are provided. The by-product streams may include blow-down (BD) including dissolved organic material (DOM), from an in situ thermal hydrocarbon recovery operation, and fine tailings including suspended fines derived from a mining and extraction operation. The techniques may involve contacting the BD with the fine tailings to induce aggregation of suspended fines and/or removal of DOM from the BD. A DOM-reduced water stream may be produced...

SYSTEME DE TRAITEMENT DES EAUX USEES EN LIT FLUIDISE LIQUIDE-SOLIDE POUR UNE ELIMINATION SIMULTANEE DU CARBONE, DE L'AZOTE ET DU PHOSPHORE

Western University

Biological nutrient removal (BNR) in wastewater treatment to remove carbonaceous substrates, nutrients and phosphorus, has recently become increasingly popular worldwide due to increasingly stringent regulations. Biological fluidized bed (BFB) technology, which could be potentially used for BNR processes, can provide some advantages such as high efficiency and compact structure. This present invention incorporates the fixed-film biological fluidized bed technology with the biological...

PROCEDE POUR INDUIRE LA POLYMERISATION D'UN POLYMERE ORGANIQUE ELECTRONIQUEMENT CONDUCTEUR

Phostech Lithium, Université du Québec à Montréal

The invention relates to a process to induce polymerization of an organic electronically conductive polymer in the presence of a partially delithiated alkali metal phosphate which acts as the polymerization initiator.
