Wick technique

Alternatively, asbestos fibers collected on the filter counted by TEM, following the modified Jaffe wick technique for sample preparation (NIOSH Method 7402, 1987).

The thin-layer wicking technique has been used to characterize textile fabrics with respect to their surface tension ys (based on the acid-base approach [84]). The technique is based on the Washburn equation and was originally introduced by Giese et al. [115] and later modified by Chibowski and Holysz [116]. The method was found to be especially suitable for characterizing (strips of) textile fabrics [123,124] and the process of surfactant and dye adsorption by the fabrics [125-127]. 

While Wicks technique was originally derived for liquid-solid systems, it has been found to apply to fluids in general and is recommended herein for gas-solids systems in addition to liquid-solid systems. 

Methods to control infiltration of water into low level waste disposal faciUties are being studied. Three techniques that may be employed separately, in sequence, or in conjunction are use of a resistive layer, eg, clay use of a conductive layer, involving wick action and bioengineering, using a special plant cover. 

Quantitative analytical treatments of the effects of mass transfer and reaction within a porous structure were apparently first carried out by Thiele (20) in the United States, Dam-kohler (21) in Germany, and Zeldovitch (22) in Russia, all working independently and reporting their results between 1937 and 1939. Since these early publications, a number of different research groups have extended and further developed the analysis. Of particular note are the efforts of Wheeler (23-24), Weisz (25-28), Wicke (29-32), and Aris (33-36). In recent years, several individuals have also extended the treatment to include enzymes immobilized in porous media or within permselective membranes. The important consequence of these analyses is the development of a technique that can be used to analyze quantitatively the factors that determine the effectiveness with which the surface area of a porous catalyst is used. For this purpose we define an effectiveness factor rj for a catalyst particle as...

ASTM D126 IP 107) that uses a modification of the standard wick-fed lamp. Many laboratories use rapid combustion techniques with an oxyhydrogen flame in a Wickbold or Martin-Floret burner (ASTM D2784 IP 243). 

Aravamudhan, Rahman, and Bhansali. [70] developed a micro direct ethanol fuel cell with silicon diffusion layers. Each silicon substrate had a number of straight micropores or holes that were formed using microelec-tromechanical system (MEMS) fabrication techniques. The pores acted both as microcapillaries/wicking structures and as built-in fuel reservoirs. The capillary action of the microperforations pumps the fuel toward the reaction sites located at the CL. Again, the size and pattern of these perforations could be modified depending on the desired properties or parameters. Lee and Chuang [71] also used a silicon substrate and machined microperforations and microchannels on it in order to use it as the cathode diffusion layer and FF channel plate in a micro-PEMFC.
