Abstract:
The invention relates to a nanowire structural element suitable for installing, for example, in a microreactor system or microcatalyst system. A template-based method is used for producing the nanowire structural element, wherein electrochemical deposition of the nanowires takes place in nanopores, preferably continuing at least until caps have formed and at least partially grown together. After reinforcing the two cover layers, the structured hollow space between the two cover layers is exposed by dissolving the template foil and removing the dissolved template material, wherein the two cover layers remain intact. The result is a stable, sandwich-like nanostructure having a two-dimensional, open-celled hollow space structure, bounded on two sides by the cover layers and penetrated by the nanowires in a columnar manner in the plane parallel to the cover layers.
Abstract:
A method is provided to prepare one or more microfluidic channels on a receptive material by applying an image-forming material to a heat sensitive thermoplastic receptive material in a designed pattern and heating the material under conditions that reduce the size of the thermoplastic receptive material by at least about 60%. In an alternative aspect, the microfluidic channels on receptive material are prepared by etching a designed pattern into a heat sensitive thermoplastic material support and then heating the material under conditions that reduce the size of the thermoplastic receptive material by at least about 60%.

A support unit for a microfluidic system includes a first support; a first adhesive layer provided on a surface of the first support; and a hollow filament laid on a surface of the first adhesive layer to have an arbitrary shape and functioning as a flow channel layer of the microfluidic system.
Abstract:
The invention relates to a micro fluid chip that leads liquids supplied from a plurality of liquid supply ports, respectively, to a minute flow passage, performs mixing and reaction (chemical reaction) of the liquids in the minute flow passage, and obtains a liquid having been processed from a liquid discharge port. A micro fluid chip 1 that leads liquids supplied from a plurality of liquid supply ports, respectively, to a minute flow passage, performs mixing/reaction of the liquids in the minute flow passage 16, and obtains a liquid having been processed from a liquid discharge port 17, the micro fluid chip comprising liquid supplies 11, 13 that supply a plurality of flows, which are formed by division of two kinds of liquids, respectively, in an alternate arrangement, and a flow flattening portion 15 provided downstream of the liquid supplies 11, 13 to be configured in flow passage such that liquids alternately arranged are decreased in dimension as they go downstream and increased in dimension in a direction, which intersects the direction of arrangement and a direction of flow, as they go downstream, to be made substantially the same or slightly large in cross sectional area in the direction of flow. According to the invention, liquids of large flow rates can be processed at high speed and an apparatus is not made large in size.
Abstract:
A manufacturing method of a microchemical chip made of a resin and having a micro channel, which comprises forming a photoresist film (2) over the surface of one side of a metal support substratum (1), stacking a photomask (4) for the formation of a channel pattern over the photoresist film (2), forming a minute-structure photoresist pattern over the metal support substratum (1) by a photofabrication technology as a flat-sheet mold, disposing the flat-sheet mold (7) or unit mold obtained by separating the flat-sheet mold (7) on the bottom of a contour forming frame for resin molding, pouring a resin into the contour forming frame for resin molding and curing the resin to form a resin structure having a micro channel formed by the mold, and attaching the resin structure having a micro channel to a flat sheet to be a lid of the micro channel; and microchemical chips manufactured by this method.
Abstract:
The invention relates to a method for producing microcomponents with at least one individual layer, which has functional layers (3) on the walls of inner structures such as flow channels. The aim of the invention is to produce microcomponents that are suitable for a variety of different applications in chemical reaction engineering, for heat-exchange applications, for mixing substances or for evaporating liquids. In particular, the inventive microcomponents should not present any problems in terms of the tightness of the flow channels. To this end, the inventive method comprises the following steps: A) producing the at least one individual layer by a) producing a first metal layer or metal film (1), b) forming the inner structures in and/or on said first metal layer or metal film (1) using suitable etching techniques and/or metal application techniques, and c) forming the functional layers (3) on the walls of the inner structures only, and then B) stacking and joining the one individual layer to a segment that closes the inner structures or joining several individual layers together and to the closing segment.
