New areas of application

In conclusion, GD-OE S is a very versatile analytical technique which is still in a state of rapid technical development. In particular, the introduction of rf sources for non-conductive materials has opened up new areas of application. Further development of more advanced techniques, e. g. pulsed glow discharge operation combined with time-gated detection [4.217], is likely to improve the analytical capabilities of GD-OE S in the near future. 

Chemical engineering undergraduate eurricula have traditionally been designed to train students for employment in the conventional chemical processing industries. The eurrent core emrieulum is remarkably successful in this effort. Chemical engineers will continue to play a major role in the ehemical and petroleum industries, but new areas of application as well as new emphases on environmental protection process safety and advanced computation, design, and proeess control will require some modifications of the curriculiun. 

The foregoing results demonstrate that the thickness of the capsule wall can be controlled at the nanometer level by varying the number of deposition cycles, while the shell size and shape are predetermined by the dimensions of the templating colloid employed. This approach has recently been used to produce hollow iron oxide, magnetic, and heterocomposite capsules [108], The fabrication of these and related capsules is expected to open up new areas of applications, particularly since the technology of self-assembly and colloidal templating allows unprecedented control over the geometry, size, diameter, wall thickness, and composition of the hollow capsules. This provides a means to tailor then-properties to meet the criteria of certain applications. 

Thus, interest in the electrochemical behavior of aluminum in aqueous solutions and anodic oxides, which, until recently, was stimulated entirely by attempts to cope with corrosion, has been enhanced by the wide new areas of application. 

In this context the integration of HPLC in the SMB concept has shown a tremendous potential for the development of separation process which are efficient and versatile as well as economically sound. The first separations of pharmaceutical compounds using HPLC-SMB technology were performed in the early 1990s [6 - 8]. Other areas of application, e. g., the fine chemicals, cosmetics and perfume industries have since followed suit [9]. Most importantly and as a reaction to the needs of these new areas of application, SMB systems smaller than the huge SMB-plants adapted to the needs of the petrochemical industry, are now commercially available. 

Solvent-modified thermosets display enhanced toughness due to the incorporation of a second phase material. A brittle-tough transition has been observed which cannot be attributed to changes in the interparticle distance. The chemically induced phase separation technique offers new routes and strategies to prepare such materials and enter new areas of applications. Hence, engineered porosity is demonstrated as a research concept developed into a toolbox for material scientists. 

The forthcoming years will offer a great deal of excitement if the CALPHAD method is extended and infused with new ideas and directions. For our part, we would like to see efforts continue which place CALPHAD on the soundest possible physical basis so that the semi-empirical nature of the subject area can be reduced. This, alongside the exciting new areas of application which are continually appearing, promises to provide the necessary scientific stimulus to keep alive the long pioneering tradition of the early workers in this field. 

LDPE), polypropylene (PP), poly(vinyl chloride) (PVC), and polyethylene tere-phthalate (PET) [48], completely new areas of application are preferred in which biodegradability is required for admission, such as applications in the medical field [50, 51]. The reason for this is obvious. When new materials enter the market, they are in competition with aheady established materials. In the case of PUB, due to its temperature stability, a competition with poly(olefin)s arises for all applications in which biodegradabUity is not required by law (Fig. 12). 

In 2007, Mullen and collaborators reported the use of multi layer graphene as a transparent electrode in a DSSC [267]. The graphene layer functioned as the anode electrode (see Fig. 32) in the cell. Although the cell overall conversion efficiency was 0.26%, feasibility was proven. This result started a new area of applications for graphene in optoelectronics. 

Hydrogen production holds renewed promise for nuclear energy, as nuclear-based hydrogen production can provide an essentially carbon emissions-free source of hydrogen, significantly reduce dependence on fossil fuels, and open a new area of application for nuclear energy that may eventually exceed the use of nuclear power for electricity. 

Much of this volume has generally applicability. Certainly Chapters 1, 3, and 4 are not in any way confined to spectroscopy applications. Significant portions of Chapters 8-10 are easily generalized. The remaining chapters, although dealing with the specifics of spectroscopy, can function as a guide to new areas of application. 

STM instruments have evolved from a complicated homebuilt instrument sensitive to vibrations into a compact, rigid, stable variable-temperature microscope, available commercially at fairly low cost. The availability of the instrumentation for STM has led to a tremendous diversification of the application of the technique, and new areas of applications are constantly being developed. 

The popularity of high resolution NMR is still unbroken and is based on its excellent information content with respect to molecular structures. New experimental techniques have opened new areas of application and improvements in spectrometer hard- and software not only fascilitate daily work of spectroscopists but bring NMR closer to the non-experienced user. 

Contrary to potentiometric methods that operate under null current conditions, other electrochemical methods impose an external energy source on the sample to induce chemical reactions that would not otherwise spontaneously occur. It is thus possible to measure all sorts of ions and organic compounds that can either be reduced or oxidised electrochemically. Polarography, the best known of voltammetric methods, is still a competitive technique for certain determinations, even though it is outclassed in its present form. It is sometimes an alternative to atomic absorption methods. A second group of methods, such as coulometry, is based on constant current. Electrochemical sensors and their use as chromatographic detectors open new areas of application for this arsenal of techniques. 

Great advances have occurred in the application of IR techniques to the study of transient phenomena, in the quant identification of trace contaminants and in the resolution of the spectra of mixts. The new techniques are known as Fourier Transform spectrometry. The following description will be necessarily brief but it is intended to highlight potential new areas of application in the study of rapid reaction phenomena ... 

The development of application is as important as the development of the device itself, the two things complementing each other, especially for new technologies and new devices. As the intention behind application development is to discover and expand new areas of application, the last section of this chapter will, taking the features of LIS into account, forecast some possible new applications and their prospects. 

Polypyridine ligands stabilize complexes of metals of Groups VB and VIB in their low oxidation states forming stable species with interesting photochemical and electrochemical properties. They nearly always form chelates with r 2-coordination, and all the chemical changes occur in the rest of the complex. However, the coordination situations may vary and the structure of the polypyridine ligand may be modified, which opens new areas of application. 

A search is now in progress for less expensive organolead additives that would allow penetration of the several-billion-gallon-per-year market for automotive engine lubricants. New areas of application are also being investigated, such as in outboard engines for boats, where... 

Because of the preparative potential of this reaction the Wittig carbonyl olefination and its manifold synthetic variants gave rise to a number of new olefin syntheses or improvements of common preparation methods in the following 30 years, and led to investigations of its mechanistic aspects and the stereochemical course. The Wittig reaction nowadays represents one of the key reactions in the preparation of natural compounds and in polyene chemistry3-5), and has found new areas of application in industrial practice 6). 

Although zwitterions are mainly considered for their novel ion conductive matrix in this chapter, they are being used as not only as solvents and catalysts for organic reactions [42] but also as organogelators [43]. Zwitterions have been screened as solvent/catalysts for several classical acid-promoted organic reactions such as the Fischer esterification, alcohol dehydrodimerization, and the pinacol/ benzopinacole rearrangement. The zwitterion containing an equimolar trifluoro-methane sulfonic acid is liquid at room temperature. Because they can work as solvent/catalysts, as shown in the reactions discussed in this chapter, zwitterionic liquids should open the door to a whole new area of applications. 

In this final chapter, an attempt is made to provide an overview of the capabilities of quantum-mechanical methods at the present time, and to highlight the needs for future development and possible future applications of these methods, particularly in areas related to mineral structures, energetics, and spectroscopy. There is also a brief account of some new areas of application, specific directions for future research, and possible developments in the perception and use of quantum-mechanical approaches. The book ends with an epilog on the overall role of theoretical geochemistry in the earth and environmental sciences. 

Membranes fabricated using the MEMS technology are finding an increasing number of applications in sensors, actuators, and other sophisticated electronic device. However, the new area of application of MEMS is creating new materials demands that traditional silicon cannot fulfill [43]. Polymeric materials, also in this case, are the optimal solution for many applications. Microfabrication of polymeric films with specific transport properties, or micromembranes, already exists, and much work is in progress [44-50].
