Extractive function

Regarding point 2, the information extraction function of chemometrics is a very valnable one that is often overlooked, especially in the industrial world. It will be mentioned later in this chapter that this function can be nsed concurrently with the instrument specialization function, rather than relying npon additional exploratory data analysis. 

As a resnlt, process analytical applications tend to focus more on automation, minimization of maintenance, and long-term reliabihty. In this more pragmatic context, the instrument specialization function of chemometrics is used even more exclusively than the information extraction function. 

Process analytical applications differ from laboratory analytical applications in that the analyzer hardware and software are in a more hostile environment, the maintenance and operations personnel in the analyzer area are typically not trained like lab technicians, and the purpose of the analyzer is most often for rapid process control rather than troubleshooting. As a result, process analytical applications tend to focus more on automation, minimization of maintenance, and long-term reliability. In this more pragmatic context, the instrument specialization function of chemometrics is used even more exclusively than the information extraction function. 

It is apparent from the foregoing discussion that both ILs and supercritical carbon dioxide do indeed offer promise as alternative solvents in the reprocessing of spent nuclear fuel and the treatment of nuclear wastes. It is equally apparent, however, that considerable additional work lies ahead before this promise can be fully realized. Of particular importance in this context is the need for an improved understanding of the fundamental aspects of metal ion transfer into ILs, for a thorough evaluation of the desirability of extractant functionalization of ILs, and for the development of new methods for both the recovery of extracted ions (e.g., uranium) and the recycling of extractants in supercritical C02-based systems. Only after such issues have been addressed might these unique solvents reasonably be expected to provide the basis of improved approaches to An or FP separations. 

The poly tensor approach introduced by Applequist [169] is a terrific organization of the problem of electrical interaction for high-level calculation because it can be continued uniformly to any order of multiple moment, any distribution of moments, and any number of interacting species. Furthermore, it can incorporate multipole polarization and hyperpolarization [170]. As such, it provides a scheme that can be coded for computer application in an open-ended fashion while also providing the formal analysis needed to extract functional forms of different electrical interaction pieces. 

Different extraction functions, for example cutting-, clipping- or iso-planes for interactive data exploration, are implemented in TECK. They are all filtering functions for the simulation data sets that help to reduce the overall visual complexity. Fig. 5.37 shows a user who interacts with simulation data in the CAVE. He is using the iso-surface and cutting-plane functions. 

Mixer-Settlers. The extraction function of bringing feed and solvent intimately together, and then allowing them to separate is frequently done in mixer-settlers. The functions may be done in separate vessels, or in different portions of the same vessels, or sequentially in the same vessel on a batch basis. As noted earlier in Fig. 3, the flows of feed and solvent can be countercurrent to each other through a series of mixer-settlers.

The pH dependence functions for the target group of transition metals are shown in Table 9.6. Cyanex 272 impregnated resins with the highest separation factors are shown in Figure 9.15. The extraction function of Zn(ll) in relation to Cu(II) and especially to Cd(II) makes this resin suitable for use in the separation of this metal couple. 

In addition to the extractable functional molecules found in biomass, we can also make additional useful functional molecules or platform molecules , such as succinic acid, lactic acid and levoglucosenone, by biochemical or thermochemical processing of the bulk cellulosic components of many types of biomass. A biorefinery is an analogue to the current petro-refinery in the sense that it produces energy and chemicals. The major differences lies in the raw material it will use, ranging from biomass to waste (Figure 1.2). 

Some of the raw materials admitted inside the SSR cannot be used directly by the SSR fabrication processes. They need to be transformed into fabrication materials through one or more specific processes. An example, which is not necessarily related to our artificial SSR, is the fabrication of steel (fabrication material) from iron ore and coal (raw materials). The SSR s ability to extract fabrication materials from sets of raw materials and parts is the fabrication material extraction function. Fabrication materials are registered in the catalog of fabrication materials while every process that is used to extract fabrication materials from raw materials and parts is documented in a fabrication material extraction process catalog. 

Macromolecules that contain two or more topologically distinct components are complex architectures that can lead to emergent properties or behaviors that are different to those of either of the individual molecular architectures. Dendronized polymers [16-19] are examples of such complex molecular architectures and are composed of a linear polymer backbone and perfectly branched dendritic side chains on each repeat unit (Scheme 1). The molar masses of such polymers emphasize the shift in thinking brought about by Staudinger s concept of macromolecules [1,2]. Individual dendronized polymers are nanoscopic objects [20-25] whose organization in bulk is determined by hierarchical processes that occur on a different set of length scales compared to conventional polymers [16,26]. By virtue of the size and shape of dendronized polymers, interest in this complex macromolecular architecture has moved toward how to extract functionality from these nanoscale molecular objects.
