Abstract:
A fluidic device is described for locally coating an inner surface of a fluidic channel. The fluidic device comprises a first, a second and a third fluidic channel intersecting at a common junction. The first fluidic channel is connectable to a coating fluid reservoir and the third fluidic channel is connectable to a sample fluid reservoir. The fluidic device further comprises a fluid control means configured for creating a fluidic flow path for a coating fluid at the common junction such that, when coating, a coating fluid propagates from the first to the second fluidic channel via the common junction without propagating into the third fluidic channel. A corresponding method for coating and for sensing also has been disclosed.
Abstract:
The principles and embodiments of the present invention relate generally to an apparatus, system, and methods for coating and calcining a catalytic substrate inline, reducing the processing time to prepare a substrate coated with catalytic material. For example, the disclosure describes a multi-station coater system comprising: a raw weight station, wherein an initial weight of a substrate is measured; a first catalytic substrate coating station, wherein a first wet coating comprising a first catalytic coating and a first carrier liquid is introduced into longitudinal cells of the substrate; a first wet weight station, wherein a wet weight of the substrate is measured; a first inline calciner module, wherein a heating fluid is introduced into the substrate to calcine the catalytic coating; and a first calcined weight station, wherein a calcined weight of the substrate is measured.
Abstract:
We describe a method of layer-by-layer deposition of a plurality of layers of material onto the wall or walls of a channel of a microfluidic device, the method comprising: loading a tube with a series of segments of solution, a said segment of solution bearing a material to be deposited; coupling said tube to said microfluidic device; and injecting said segments of solution into said microfluidic device such that said segments of solution pass, in turn, through said channel depositing successive layers of material to perform said layer-by-layer deposition onto said wall or walls of said channel. Embodiments of the methods are particularly useful for automated surface modification of plastic, for example PDMS (Poly(dimethylsiloxane)), microchannels. We also describe methods and apparatus for forming double-emulsions.

This application concerns a tool for coating a monolithic shaped catalyst. The tool is part of a coating station and serves to hold and fix the monolith while coating is progressing.
Abstract:
A method of coating a substrate with a liquid comprising a catalyst component, which substrate comprises a plurality of channels, wherein the method comprises: (a) holding the substrate vertically; (b) introducing the liquid into the substrate through the open ends of the channels at a lower end of the substrate; and (c) after the lower end of the substrate has been part-filled with the liquid, applying a vacuum to the open ends of the channels at the upper end of the substrate while introducing the liquid into the substrate.
Abstract:
A coating apparatus includes modular interfaces and substrate receptors for accommodating various shapes and sizes of monolith substrates when coating layers are applied onto the monolith substrates. The monolith substrates are laterally surrounded by an elastically deformable sleeve that prevents lateral leakage of a vacuum out of the monolith substrate when a vacuum is applied to opposing ends of the monolith substrate, thereby eliminating needs for bulky vacuum chambers. The coating apparatus also includes valves and control apparatus that enable excess precursor liquid to be drained from monolith channels in-situ, without the use of additional spin-drying steps. Coating methods for using the coating apparatus are provided.
Abstract:
A method of applying a coating to a glass sleeve with an inner surface and an outer surface, the glass sleeve configured as a part of a solar-receiver tube, is provided. Thereby, the coating is solely applied to one of the surfaces of the glass sleeve. A method of fixing such glass sleeve in an interior of a coating tank, such coating tank and a fixing arrangement for fixing such glass sleeve in an interior of a coating tank, is also provided.
Abstract:
Systems and methods for altering the appearance and/or texture of a vehicle surface include installing a vest relative to a vehicle surface such that an exterior side of the vest, spaced from the vehicle surface, defines a fluid-tight space between the vehicle surface and the exterior side of the vest. Visual media can be provided into and from the fluid-tight space using one or more ports, the exterior side being at least partially transparent or translucent such that the visible media within the fluid-tight space are visible through the exterior side of the vest, thereby allowing the repeatable alteration of the appearance of the surface.

Abstract:
A method and apparatus for applying a uniform membrane coating to a substrate, such as a honeycomb structure, having a plurality of through-channels, wherein the through-channels have an average diameter of less than or equal to 3 mm. The method includes providing a liquid precursor comprising membrane-forming materials to the substrate and applying a pressure differential across the substrate. The pressure differential causes the liquid precursor to travel uniformly through the through-channels, depositing the membrane-forming materials on the walls of the through-channels and forming the membrane on the walls of the through-channels. The apparatus includes a chamber capable of holding the substrate and of maintaining a pressure differential across the plurality of through-channels.
