Micro cross-current

The behavior discussed above shows that in the regime of stable macropore formation the pore current divided by the cross-sectional area of the pore is equal to Jps- Because of the hemispherical shape of the pore, only the current density at the center of the tip is equal to /PS, while the interfacial current density decreases towards the pore wall with a cosine dependency, as shown in Fig. 9.12f [Zh3]. As a result the pore walls become covered with micro PS film, while the center of... 

Fig. 50.1. Photograph of the Immuspeed instrument coupled to a portable computer comprising the Immusoft programme serving to load the test protocol, to run the assays, and to process the results. The figure also shows an artist view of the 8-channel Immuchip cartridge used in the current work and a schematic drawing of a micro-channel cross section with inlet, outlet, working electrodes, and electrical connection tracks the arrow shows the position of the cartridge insertion into the reception compartment of Immuspeed which comprises a temperature controller below the chip.

Integrated reactors One type of integrated reactor is micro structured heat exchanger/reactor concepts, which may work as cross- or counter-flow reactors. Another type couples endothermic and exothermic reactions in two separate flow paths normally operated in the co-current mode. Both reactor types are designed as prototype components of future fuel processors for mobile applications. 

EMP. EMP (electron microprobe) analysis was performed with a Cameca sx-50 microprobe equipped with WDS detectors. K-alpha lines were used to analyze AJ, Si, P, S and Zn, and L-alpha lines were used for Ce, Pb and Pd. Data was collected using a 20kV accelerating voltage, 60nA beam current, 1 micron spot size and 3 micron step increments across the cross-sectioned, polished fillettes. Elements were calibrated against their respective standards, supplied by Micro-Analysis Consultants Limited. 

In a typical formulation, an ethylene-n-butylacrylate-carbon monoxide (60/30/ 10) terpolymer (60 wt%) is melt compounded in a twin-screw extmder with PVC (30 wt%) along with an optional, nonvolatile plasticizer such as trioctyl trimellitate (10 wt%) such that the ethylene terpolymer dispersion was cured in situ during the mixing by catalytic amounts of a suitable peroxide (0.3 %) and a bismaleimide crosslink promoter (0.2 %). It is believed that the initial homogeneous miscible melt blend later forms the micro phase-separated mbber domains as the selective rubber cross-Unking progresses. Currently, such TPV blends are commercially sold as Alcryn melt-processable rubbers by Advanced Polymer Alloys division of Ferro.
