Abstract: A mixing and/or conveyance method and a mixing and/or conveyance device for a fluid substance, comprising a sample chamber, a cavity communicating with the sample chamber, said cavity being configured for accommodating a compressible medium, and a sound source that may be coupled to the compressible medium for the production of a fluctuation in pressure in the compressible medium. In the region of its mouth, the cavity is designed such that, in the case of an expansion in the volume of the compressible medium in the cavity, a directed fluid stream of the fluid substance escapes from the cavity through its mouth. A sample processing chip (‘lab on a chip’) comprising such a mixing and/or conveyance device.

Abstract: A catalyst for steam reforming of methanol, which includes a carrier material comprising a metal oxide and deposited thereon a) indium oxide (In2O3) and at least one further metal from the group of palladium (Pd), platinum (Pt), rhodium (Rh) and iridium (Ir) and/or b) an alloy comprising indium and at least one further metal from the group of palladium (Pd), platinum (Pt), rhodium (Rh) and iridium (Ir), as catalytically active substances.

Abstract: A microfluidic arrangement including a substrate in which a mircofluidic structure having several adjacent channels and at least one common supply line, into which the adjacent channels merge, is formed. Each of the adjacent channels form the cylinder of a cylinder-piston arrangement for receiving an associated piston. A method for producing the type of microfluidic-arrangement is also disclosed.

Abstract: System for the in vitro transcription and translation of membrane proteins comprising i) a micro-fluidic chip having at least one micro-fluidic reaction chamber and micro-fluidic channels to allow fluid to flow through the chip and into and from the at least one reaction chamber, ii) the at least one micro-fluidic reaction chamber being provided with at least one electrode base plate of conductive or semi-conductive material, and iii) lipid vesicles or a lipid membrane being bound or tethered to the at least one electrode base plate either directly or through spacer molecules.

Abstract: The present invention concerns a measurement chip (1) for carrying out measurements of transmission and/or emission and/or scattering of light by a fluid sample in an operator unit, wherein the measurement chip has a base plate (2) produced from a transparent polymer material, provided in the base plate (2) are at least one measurement cell (3) for receiving a fluid sample and fluid passages (4, 4) for supplying and discharging fluid to and from the measurement cell (3), and provided in and/or on the base plate (2) outside the measurement cell (3) are mirror surfaces (5) which are so arranged that they direct light emitted from and/or scattered by a fluid sample in the measurement cell (3) from the measurement chip (1), preferably in the direction of a light detector provided in an operator unit.

Abstract: A method for fabrication of micro heat exchangers, which enable an efficient heat transfer between two flowing media. In a first processing step, a plastic layer is structurized by means of photolithography, x-ray deep lithography, or laser ablation. This plastic structure is galvanically molded in a second processing step, preserving the structural properties. The resulting metallic microstructure, which is the inverse of the original structure, is used as a shaping insert to produce the individual layers from which the micro heat exchanger is assembled. The method according to the invention makes it possible to cheaply produce large numbers of micro heat exchangers.
