Abstract: Quaternary ammonium, betaine, or sulfobetaine compositions derived from fatty amines, wherein the fatty amine is made by reducing the amide reaction product of of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives and a secondary amine, are disclosed. Quaternary ammonium, betaine, or sulfobetaine compositions derived from fatty amidoamines, wherein the amidoamine is made by reacting of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives and an aminoalkyl- substituted tertiary amine, are also disclosed. The quaternized compositions are advantageously sulfonated or sulfitated. In one aspect, the ester derivative of the C10- C17 monounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin. The quaternary ammonium, betaine, and sulfobetaine compositions and their sulfonated or sulfitated derivatives are valuable for a wide variety of end uses, including cleaners, fabric treatment, hair conditioning, personal care (liquid cleansing products, conditioning bars, oral care products), antimicrobial compositions, agricultural uses, and oil field applications.

Abstract: Linvention concerne un système dalerte sociale comprenant une unité détectrice de chute, portée par lutilisateur, munie dun accéléromètre servant à détecter les chutes. Un contrôleur surveille un signal daccélération dépassant un seuil de réveil ou de départ et, en réaction, fait la distinction entre un événement constituant une chute et un événement ne constituant pas une chute en se fondant au moins sur le signal daccélération. Une unité de comptage comptabilise les événements ne constituant pas une chute pendant une période de temps surveillée (un jour par exemple). Une unité de signal dalarme produit un signal dalarme lorsque le décompte des événements ne constituant pas une chute pendant la période de temps surveillée est inférieur à une valeur seuil.

Abstract: Une nouvelle approche est conçue pour le développement de matériaux conducteurs polymères organiques synthétisés à partir de nanocomposites de cellulose nanocristalline (NCC) et de polyaniline (PANI). Le procédé met en jeu une polymérisation radicalaire oxydante d'aniline en présence de NCC utilisant soit une polymérisation in situ soit une polymérisation en émulsion. Le matériau nanocomposite NCC-PANI résultant peut être obtenu sous forme de film ou de poudre et présente des propriétés conductrices électriques typiques de matériaux semi-conducteurs. A la différence de la PANI, un polymère conducteur fragile, les matériaux nanocomposites NCC-PANI peuvent être conçus pour posséder une flexibilité significative, une résistance significative et/ou une dureté significative en raison du NCC agissant comme échafaudage de renforcement. En fonction des conditions de préparation, les conductivités électriques pour les matériaux nanocomposites NCC-PANI préparés selon cette invention, se situent dans la plage de 9,98 x 10-5 à 1,88 x 10-2 S.cm-1 ; ils pourraient également avoir une dureté > 0,189 GPa ou être transformés en films flexibles de résistance à la traction de l'ordre de 9,74 MPa et d'étirement de l'ordre de 0,54 %. Ces propriétés électriques et mécaniques uniques rendent ces matériaux appropriés pour une utilisation dans une diversité de produits industriels à valeur ajoutée, tels que des batteries, des produits électroniques, des capteurs électriques, des membranes de séparation, des revêtements anti-statiques pour des applications aérospatiales, ainsi que des revêtements anti-corrosifs pour des automobiles et autres applications industrielles.

Abstract: A method for concurrently transporting and removing trace amount levels of heavy metals such as mercury from produced fluids such as natural gas, with the injection of a complexing agent and a hydrate inhibitor into the pipeline for use in transporting the produced fluid. Volatile mercury in the natural gas is removed while the produced fluid is being transported in the pipeline, with the hydrate inhibitor suppressing or decreasing the formation of the hydrate that would cause plugging in the pipeline. The complexing agent reacts with the volatile mercury in the natural gas, forming precipitate or soluble mercury complexes in the aqueous phase. The aqueous phase containing the hydrate inhibitor, unreacted complexing agent, and mercury complexes is subsequently recovered and can be re-used in the pipeline.
