Electroosmotic flow velocity, Veof, is a function of the magnitude of the applied electric field and the buffer solution s electroosmotic mobility, )J,eof. 

Input/Output statements—Two boolean functions that are useful in input processing are EOF, which is TRUE if the pointer is currently at the end of the input file and FALSE otherwise, and EOLN, which is TRUE if the pointer is at the end of the current input line and FALSE otherwise. 

EOF Returns TRUE if the end of file has been reached, otherwise returns... 

Extracellular factors that induce mitosis are termed mitogens. Some of these, such as epidermal growth factor (EOF) and fibroblast growth factor (FGF) are now being characterized.

Liquid transport is achieved by hydrostatic action, pumping or electroosmotic flow (EOF). So far, chip reactors have been employed at low to very low flow rates, e.g. from 1 ml min to 1 pi min. Applications consequently were restricted to the laboratory-scale or even solely to analytics. However, this is not intrinsic. By choosing larger internal dimensions, similar throughputs as for the other classes of liquid or liquid/liquid micro reactors are in principle achievable. 

In addition to the general improvement of transfer in micro reactors, there is evidence that the voltage of electroosmotic flow (for EOF see [14]) in combination with the large internal surface area in glass chips can induce hydroxide ion formation [6]. Concerning catalyst loss, there is no obvious direct correlation rather, micro reactors can act as mini fixed beds fixing heterogeneous catalyst particles. 

The aim of one study was to show that arrays of cycloadducts, from various precursors, can be made in a single run in one chip [18]. In addition, this study served more generally to demonstrate the feasibility and advantages of pressure-driven flow in micro chips exemplary of one prominent organic reaction. The advantages and drawbacks of pressure-driven flow as compared with electroosmotic flow (for EOF see [14]) were discussed [18]. 

C) [9, 10]. It is said to be the first example of a heated organic reaction performed in a glass chip reactor imder electroosmohc flow (EOF) control [10] (for EOF see [14]). The performance of this reactor for room-temperatare reactions such as the Wittig reaction and Suzuki coupling was demonstrated before. 

This carbon-carbon bond-generating reaction can be used extensively over a wide range of chemistries [11]. As the reaction is an equilibrium process, needing the removal of water to obtain high yields, chemical means have to be used to accomplish this task. 1,3-Dicyclohexylcarbodiimide (DCC) is a commonly used reagent for this purpose. Alternatively, molecular sieves find use for conventional processing, but are not so favorable for micro-reactor processing, because the sieve needs to be inserted into the micro channel (additional fabrication expenditure) and may disrupt the liquid transport if EOF is applied.
