    Abstract: A quantum dot-polymer nanocomposite sensor array for chemical vapor sensing includes plurality of sensors respectively formed by different nanocomposite films. Each nanocomposite film is formed by a plurality of QDs and a polymer solution made from a polymer and a corresponding solvent. The plurality of sensors are disposed on a substrate for impingement by an excitation light source. Fluorescence emission intensity of the sensors is measured for a preselected duration of time and then the sensors are placed into contact with a chemical vapor. The changes in fluorescence emission intensity for all sensors are detected over time and the combined changes in fluorescence are compared to establish a unique combined response for each target chemical vapor. Using this unique combined response from a sensor array, target chemical vapor can be detected, classified, and identified.

    Abstract: Graphene glue contains graphene which is directly used as adhesives to bind different components/materials together. Materials such as metal powders, carbon powders, metal oxides, polymers, cellulose, and bio-molecules can all be glued by graphene glue on substrates. Graphene glue as binders can exhibit both the benefits of graphene and the glued materials, showing perfect accumulative effects. Compression can enhance the adhesion, electronic and thermal conductivity of graphene glue.

    Abstract: The invention pertains to a method for providing a metallic or concrete surface of a chemical installation with a coating, which comprises the steps of—providing a two-pack coating composition wherein the first pack comprises an epoxy resin and the second pack comprises an amine curing agent for the epoxy resin, the coating composition further comprising an organoboron compound of the formula BX1X2X3, wherein X1, X2, and X3 are independently selected from —Y1 and —OY2, wherein Y1 is independently selected from monovalent C1-C12 alkyl groups and monovalent C6-C12 aryl groups, and Y2 is independently selected from monovalent C1-C12 alkyl groups and monovalent C6-C12 aryl groups, and wherein at least one of X1, X2, and X3 is an —OY2 group,—combining the first pack and the second pack to form a coating composition,—applying the coating composition to the surface of a chemical installation to form a coating layer, and—allowing the coating layer to cure at a temperature in the range of 0 to 50° C. A chemical installation provided with a lining of a cured coating composition as specified above, and a suitable coating composition, are also claimed. It has been found that the coating composition as specified herein has a wide application spectrum, and a high chemical resistance.
