Chipping, basics

Gimsa, J., 2012. AC-electrokinetic applications in cell chips basic understanding and modeling of structural polarization effects. IFMBE Proc. 37, 1242—1245. [Pg.534]

Electroosmotic flow (EOE) is thus the mechanism by which liquids are moved from one end of the sepai ation capillai y to the other, obviating the need for mechanical pumps and valves. This makes this technique very amenable to miniaturization, as it is fai simpler to make an electrical contact to a chip via a wire immersed in a reservoir than to make a robust connection to a pump. More important, however, is that all the basic fluidic manipulations that a chemist requires for microchip electrophoresis, or any other liquid handling for that matter, have been adapted to electrokinetic microfluidic chips. [Pg.324]

Fluidized-bed process incinerators have been used mostly in the petroleum and paper industries, and for processing nuclear wastes, spent cook liquor, wood chips, and sewage sludge disposal. Wastes in any physical state can be applied to a fluidized-bed process incinerator. Au.xiliary equipment includes a fuel burner system, an air supply system, and feed systems for liquid and solid wastes. The two basic bed design modes, bubbling bed and circulating bed, are distinguished by the e.xtent to which solids are entrained from the bed into the gas stream. [Pg.155]

Basic Explosives Manufacture. The major quantities and the toughest problems are here. They include a) acid waters, treated with lime or soda ash, chemical washes, spills, washdowns b) Red Water from TNT purification. A complex, brick-red soln of Na nitrate, Na sulfate, Na sulfite, Na nitrite, and about 17% organics which include sulfonated nitrotoluene isomers and complex, unidentified dye-bodies c) dissolved expls, eg, Pink Water which is approx lOOppm TNT in w d) suspended expl particles — dust and chips and e) sometimes solvents such as acet, benz, and dimethyl aniline... [Pg.797]

Silicon s atomic structure makes it an extremely important semiconductor. Highly purified silicon, doped with such elements as boron, phosphorus, and arsenic, is the basic material used in computer chips, transistors, sUicon diodes, and various other electronic circuits and electrical-current switching devices. Silicon of lesser purity is used in metallurgy as a reducing agent and as an alloying element in steel, brass, and bronze. [Pg.310]

Regenerated cellulose film (RCF) is basically a form of cellulose. Wood chips are immersed in a caustic solution and, after a maturation period, dissolved in carbon disulfide. This solution is subsequently extruded through a die into an acid solution, where regeneration occurs. The resulting film is then washed and plasticized with various glycols and humectants. [Pg.596]

The development of protein chip assays to determine protein function using purified components is a rapidly advancing area. Automated systems for the assay of protein function on chips in parallel for thousands of proteins simultaneously will likely be available in the next few years. These miniaturized arrays will be useful for basic research as well as for diagnostics and drug development. For instance, the combination of protein chips with combinatorial chemistry will allow the simultaneous screening of vast collections of small molecules against vast collections of potential target proteins. [Pg.108]

Biocatalysts Ltd. works through customer agreements with customer, so far, they already hold exclusivity agreements with some blue chip companies around the world. The R D program is focused on the development of new enzymes and enzyme complexes mainly identified by customers. British Universities undertake most of the needed basic research into new enzymes through allegiances with Biocatalyst Ltd. This allows the in-house scientists to focus onto the customers needs, whilst keeping full up to date with the latest developments in bioresearch. [Pg.250]

Similarly, AVX has come up with improved IDC capacitors called LICA capacitors (low inductance chip array). They were developed in a joint effort between AVX and IBM. Their basic principle also remains the same—flux cancellation by opposite current flows. (See Figure 4-18.) They look and feel like regular IDCs (and need to be laid out similarly), but they have an improved internal electrode structure to further minimize ESL. See how the currents are forced inside the chip in Figure 4-19. [Pg.123]

The use of biochips in basic biological research has provided information that was heretofore inaccessible. Protein chips, especially functional microarrays, are used to... [Pg.367]
