APPAREIL ET METHODE DE MISE EN VALEUR DU CHARBON

Université de l'Alberta

A method of upgrading coal is disclosed, the method comprising: subjecting the coal to a hydrothermal dewatering process at a temperature and a pressure above ambient conditions to produce dewatered coal; removing ash tailings from the dewatered coal to produced reduced ash dewatered coal; and producing a coal water slurry with the reduced ash dewatered coal. An apparatus for upgrading coal is also disclosed, the apparatus comprising: a hydrothermal dewatering reactor connected to receive...

EMETTEURS A BASE DE METAMATERIAU POUR THERMOPHOTOVOLTAIQUES

Université de l'Alberta

A thermal emitter is provided, having a periodic structure operating in the limit of bulk metamaterial responses; the periodic structure thermally emitting at high temperatures in a specified narrow wavelength of a predeterrmined resonance.

PRODUITS DE CONSTRUCTION A LIAISON CARBONATE ISSUS DE RESIDUS DE FABRICATION DE L'ACIER ET SON PROCEDE DE PRODUCTION

Université McGill

A building product is made from granular material and a binder that includes steel slag. A process for making the building product includes combining the granular material and the binder and then curing the combined granular material and binder with carbon dioxide. A building material includes a mixture of steel slag and a silica-rich material. The steel slag and silica-rich material is treated by heating. The silica-rich material may be waste glass and/or fly ash. A process for making the...

SYSTEMES ET PROCEDES POUR L'UTILISATION D'EAU PRESENTANT UNE FORCE IONIQUE COMMUTABLE

Queen's University

Methods and systems for use of switchable water, which is capable of reversibly switching between an initial ionic strength and an increased ionic strength, is described. The disclosed methods and systems can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions, desalination, clay settling, viscosity switching, etc. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with C02, CS2 or COS or...

STRUCTURES PROTÉIQUES FONCTIONNELLES ET PROCÉDÉS DE PRÉPARATION ET D'UTILISATION DE CELLES-CI

Université de l'Alberta

La présente invention concerne des constructions tridimensionnelles fonctionnelles incorporant des matériels biologiques produites par des techniques de fabrication additive. Le matériel biologique peut être une protéine qui est incorporée dans la construction en trois dimensions par l'intermédiaire d'un groupe fonctionnel photo-inductible et 0 conserve sa fonction native. Dans un mode de réalisation, le matériel biologique est une bactériorhodopsine et la construction comprend un catalyseur...

POLYMERES A COMMUTATION THERMIQUE POUR L'ASSECHEMENT DES FINES DE CHARBON

Université de l'Alberta

A flocculating agent that comprises a complex of a metal salt and multiple strands of a temperature sensitive polymer. A process for separating coal fines from an aqueous liquid using a flocculent having a critical flocculation temperature, said critical flocculation temperature being the temperature below which flocculent is hydrophilic and forms floccules with fines and above which the flocculent is hydrophobic, which comprises adding to the aqueous liquid an effective amount of the...

PROCEDES ET MICRO-ORGANISMES DE PRODUCTION DE 1,3-BUTANEDIOL

Université de Toronto

A non-naturally occurring microorganism having a 1,3-BDO pathway is provided. The microorganism expresses at least one of the following 1,3-BDO pathway enzymes: an aldolase that catalyzes condensation of two acetaldehydes to produce 3-hydroxybutanal; and an aldo- ketoreductase, oxidoreductase, aldehyde reductase or alcohol dehydrogenase that reduces 3- hydroxybutanal to 1,3-BDO. The organism may further express one or more enzymes for producing acetaldehyde. A biosynthetic process involves...

DÉTECTION ET RÉCUPÉRATION D'ÉLÉMENTS CHIMIQUES À PARTIR DE FLUIDES AVEC UNE PROTÉINE TÉTRABRACHION

University of Manitoba

La présente invention concerne des utilisations et des procédés pour l'utilisation de compositions comprenant une protéine tétrabrachion issue de Staphylothermus marinus ou un fragment de celle-ci pour la détection et/ou la récupération d'un élément chimique à partir d'une solution ou d'une suspension. Le fragment de la protéine tétrabrachion comprend la protéine RHCC (Right Handed Coiled Coil).

METHODE DE PREPARATION DE CARBONE ACTIVE

Université de l'Alberta

A method of preparing activated carbon, is disclosed, comprising: exposing carbonaceous material to microwave radiation in the presence of water to produce activated carbon..

PROCEDES ET SYSTEMES POUR LA SPECIATION CHIMIQUE QUANTITATIVE DE METAUX LOURDS ET D'AUTRES POLLUANTS TOXIQUES

Université McGill

This invention relates to systems and methods for measuring quantitatively multiple species or heavy metals, including mercury, and other toxic pollutants. More specifically, the systems and methods of the invention allows for determination of the analytes even at very low concentration, through concentration on a collection interface, desorption and analysis by mass spectrometry. The invention also provides for a portable device or kit for modifying an existing mass spectrometer.
