Carbon nanotubes (CNTs) are a set of materials with different structures and properties. They are among the most important materials of modern nanoscience and nanotechnology field. They combine inorganic, organic, bio-organic, coUoidal, and polymeric chemistry and are chemically inert. They are insoluble in any solvent and their chemistry is in a key position toward interdisciphnary applications, for example, use as supports for catalysts and catalytic membranes [20, 21]. 

SAM, conventional LB films are also useful for some applications in the nanotechnology field [11]. In this way, self-assembling can be defined as not only simple spontaneous aggregation but also functionalized organization. 

Finally, we consider the method for anisotropic ionic conductivity. Anisotropic ionic conductivity is a phenomenon that appears in a sample undergoing liquid crystalline phase or micro phase separation. In the nanotechnology field such samples are expected to yield important materials because they can raise the value of ion conduction. To measure the anisotropic ionic conductivity, one has to design a special cell. Figure 6.5 shows an example of a cell shaped Uke a comb [8]. In the comb-shaped cell, the ionic conductivity is measured between two teeth of the comb. As the liquid crystalline molecules orient perpendicularly on the glass substrate, the ionic conductivity is obtained along with the minor axis. The important task is to prepare the specific phase homogeneously in the measurement cell. The details will soon be presented in published papers. 

This chapter gives an overview of the synthesis procedures and appUcations of zeoUte membranes (gas separation, pervaporation, zeolite-membrane reactors), as well as new emerging appUcations in the micro- and nanotechnology field. Related areas such as new zeoUte and zeoUte-related materials for membranes, alternative supports, and scale-up issues are also discussed. 

Electroless deposition is a very useful approach in the production of various metallic and ceramic nanostructures. In this section, a brief review of electroless deposition processes used in nanotechnology field is presented. 

There are several players in this field who have developed silica and polymer based functionalized metal scavengers - SiliCycle, Polymer Labs, Reaxa and Aldrich are key players in the medicinal and process chemistry fields. ChemRoutes Corporation has carried out significant research effort in this field, commercialized by the above-mentioned players, and is now developing novel technologies in the metal scavenging area for the nanotechnology field. Examples of the chemistries commercialized by the various players are given below. 

In the nanotechnology field, carbon-based materials and associated composites have received special attention both for fundamental and applicative research. In the first kind, carbon compounds may be included, often taking the form of a hollow spheres, ellipsoids, or mbes. Spherical and ellipsoidal carbon nanomaterials are referred to as fullerenes, while cylindrical ones are called nanombes and nanofibers. In the second class, one includes composite materials that combine carbon nanoparticles with other nanoparticles, or nanoparticles with large bulk-type materials. The unique properties of these various types of nanomaterials provide novel electrical, catalytic, magnetic, mechanical, thermal, and other features that are desirable for applications in commercial, medical, military, and enviromnental sectors. This is the case for conducting polymers (CPs) and carbon nanombes (CNTs) [1-5]. 

Richard Feynman is generally credited with opening the nanoscience and nanotechnology fields in his visionary 1959 lecture entitled There s Plenty of Room at the Bottom . In his Lectures on Physics, Feynman made the following statement (61) ... And lo and behold The chemists are almost always correct. The context of this quote is the elucidation of molecular structures. 

Toward this end, the most advanced scientific techniques in materials theory, synthesis, and characterization are being brought to the table on an international scale, and powerful synergies among researchers in the PEC, photovoltaics, and nanotechnology fields are emerging in collaborative pursuit of the PEC quest [9]. 

In the next sections, we will discuss several DoE methodologies that can be used by experimenters in the nanotechnology field to gain a better understanding of a process.

Applications of porphyrin-nanotube composites are, by and large, mainly in the photovoltaic [154-156] and optoelectronic [157,158] fields, that are out of the scope of the present chapter. Nevertheless, a number of interesting reactions have been investigated with porphyrin-CNT systems that can be regarded as nanoreactors. Moreover, being monodimensional conducting polymers, they are expected to play a role in different nanotechnology fields [159,160]. 

The search for new and/or improved catalysts appears to be a never-ending process that has recently received impetus because of developments in the nanotechnology field l This predicament is further exacerbated because small changes in the operating temperature and/or pressure, or small change in yields or product distribution can have significant economic impact on the process of concern.
