Development of New Applications

LVHV applications have not developed rapidly. Initial concepts were developed for industrial applications in the 1950s and 1960s. Refinements were made and commercial products have been available from the 1970s until the present time. Unfortunately, there has not been much development of new applications. 

Mechanism The understanding of mechanisms in catalytic reactions is sometimes crucial for the creative development of new applications. In a first approach, the main interest was to develop high surface area titanium nitride as a material for catalytic applications and, therefore, evaluation of catalysts prepared under different conditions was performed. 

Cardanol, a main component obtained by thermal treatment of cashew nut shell liquid (CNSL), is a phenol derivative having mainly the meta substituent of a C15 unsaturated hydrocarbon chain with one to three double bonds as the major. Since CNSL is nearly one-third of the total nut weight, a great amount of CNSL is obtained as byproducts from mechanical processes for the edible use of the cashew kernel. Only a small part of cardanol obtained in the production of cashew kernel is used in industrial fields, though it has various potential industrial utilizations such as resins, friction-lining materials, and surface coatings. Therefore, development of new applications for cardanol is very attractive. 

Although the effect of nutrients and classical toxicants (e.g. heavy metals, herbicides) is well known, that of the so-called non-PS in biofilms is still largely unknown. Furthermore, the combination of effects, which operate at the basin scale, requires complex approaches. Therefore, the response of biofilms to these situations should trigger the development of new applications and higher standardisation in the use of biofilms. The standardisation of methods and procedures is a challenge for the future research on the use of natural and laboratory biofilms. 

Development of new applications of radiation modifications of the properties of polymers in high technology industries such as electronics and the exposure of polymer materials to radiation environments as diverse as medical sterilization and the Van Allen belts of space have resulted in a renewed interest in fundamental radiation chemistry of polymers. 

Discontinuous (batch) processes are carried out in pressure vessels (autoclaves) where DMC is maintained as liquid by autogenous pressure. Instead, CF reactions at atmospheric pressure require that both DMC and the reagent(s) in the vapor phase come into contact with a catalytic bed a constraint that has spurred the development of new applications and alternative reaction engineering, namely, GL-PTC and the continuously fed stirred-tank reactor (CSTR). 

A too restrictive definition of the identified use of a substance in registration may become a constraint on innovation with regard to the development of new applications or new preparations. 

Hitachi Chemical is considering developments of new applications for its crosslinked PE foam. It has been used as roofing material, cushioning and insulation. It is a closed-cell type and does not absorb moisture or water, is chemical resistant and highly shock absorbant. It is easy to handle and may be processed using conventional equipment. Applications are expected to widen to meet future needs. 

In this chapter, some important systems that are complex, as compared to more fundamental examples described previously, will be explained. This is useful since scientific developments change as more and more theoretical knowledge is obtained. The examples discussed in this chapter are designed to indicate how surface and colloid chemistry have helped in the development of new applications in recent years. 

Abstract Bismuth(III) salts are currently considered efficient and ecofriendly reagents and catalysts for the development of new applications in organic synthesis. The preparation of bismuth(III) triflate and its analogues is reviewed as well as some of their applications to the synthesis of bulk chemicals via electrophilic addition and cyclization reactions. The use of bismuth(III) salts in the development of new chemical processes involving steroids and terpenes as substrates is also discussed. 

Tubocurarine acts as a competitive inhibitor in the nicotinic acetylcholine receptor, meaning that the nerve impulse is blocked by this alkaloid. Tubocurarine is used in surgical practice as a muscle relaxant. These alkaloids have an observably large spectrum of activity and possible applications. Their utilization in the development of new applications is therefore relatively active in modern medicine. 

Several texts have been published that contain information on applications. In addition, the Atomic Spectrometry Updates published in the Journal of Analytical Atomic Spectrometry offer invaluable help in the development of new applications in the laboratory. Nearly all the applications of analytical atomic spectrometry require the sample to be in solution. Where possible, samples should be brought into solution to give analyte levels of at least 10 times the limit of detection, known as the limit of determination. 

Growth after the 1970s was thus driven by the development of new applications not only in metallurgy, but also in new markets, such as food or healthcare. The primary drivers of innovative applications were productivity, quality, and environmental improvements. The big players benefited the most - besides economies of scale in production and distribution, they had the backing of scale in applications know-how. 

Production costs for biopolymers still remain high because of the relatively low volumes being produced and the profitability of biodegradable plastics products remains low. Hence, volumes must be increased if unit costs are to fall and profitability is to improve. The development of new applications will be crucial to achieving higher production volumes and generating the profitability needed for further investment in production capacity. 

The current high price of commercially available conductive inkjet inks is hindering development of new applications, thus there is a demand for less expensive solutions. R D efforts will continue to be devoted to development of jettable conductive inks, and new processes and/or cheaper materials, such as copper or organic conductors, are expected to find their way into this market. 

The growth in both variety and scale of gas-pliase adsorption separation processes, particularly since 1970, is due in part to continuing discoveries of new, porous, high-surface-area adsorbent materials (particularly molecular sieve zeolites) and, especially, to improvements in the design and modification of adsorbents. These advances have encouraged parallel inventions of new process concepts. Increasingly, the development of new applications requires close cooperation in adsorbent design and process cycle development and optimization. 

Although ASA has been marketed for more than 30 years, it is still a product with a considerable potential for new applications owing to the well-balanced cost-property relationship. The strength of ASA lies in the unique combination of its good weatherability, toughness, surface properties and resistance to chemicals. To be successful as an ASA supplier in the future the following prerequisites seem to be mandatory back integration for the main raw materials, innovative process and development, development of new applications coupled with a reliable and skilled technical customer support service. 

Although the coining of the term metabolomics has been relatively new, an explosion of publications has occurred in this field plus a realization that many researchers already were doing similar studies, albeit without an -omic tag before the word. It has not been possible to review all the applications of metabolomics fully, and the applications will increase. In addition to the development of new applications, the development of the analytical approaches will also take center stage as researchers push back the limits of detection of NMR spectroscopy, mass spectrometry, and other analytical approaches. In addition to these wet lab developments, both the pattern recognition approaches used to process metabolomics and the metabolomic databases used to identify metabolites need to be developed or expanded. In this respect, an excellent place to start on the arduous journey to biomarker discovery through metabolomics is the current metabolomic databases found on the web that make standard spectra freely available (68-70). 

Effective utilization of biomass for value-added chemical product synthesis will require development of new applications of important unit operations. Carbohydrate recovery from the biomass is the key near-term application for production of commodity chemicals. Protein recovery will continue to have an important niche market in tlie purified form as food and a larger low-value market in the crude form as animal feed. Important processing information for carbohydrate depolymerization can be found in the literature from biochemical conversion of biomass. New process applications of separation technologies are just now being developed and refined for use with biomass-derived carbohydrate and protein streams. The use of an aqueous processing environment for carbohydrates will require careful consideration of the differences that type of environment entails, such as the effect on catalyst formulations. 

In our opinion, this development was facilitated mainly by two key factors the technical progress of all analytical methods, particularly in the fields of NMR spectroscopy and X-ray diffractometry, and the plenty of structural data meanwhile available for metal complexes of model compounds of carbohydrates. The basic research on the structural chemistry of the latter complexes followed by a transfer of the thereby gained knowledge in stability and regioselectivity of metal coordination into reducing carbohydrates has proved to be very successful. By this way, the improvement of existing and the development of new applications of metal complexes of carbohydrates, which provide a cheap and renewable feedstock, is merely a matter of time. 

One of the most powerful aspects of the HCToolkit is its extensibility in Perl. This allows rapid development of new applications for specific tasks. For example, an included extension quickly calculates and plots a pressure-temperature phase diagram at user-specified conditions (PT-PhaseDiagram.pl, found in the /apps subdirectory of the distribution tree). In fact, a scripting application that does some sort of equilibrium calculation needs only do four things create a database connection, use that connection to load a pre-defined fluid, initialize the flash object and do the flash calculation. These steps are shown in Figure 4. 

Although it might seem that pulse-heating has already started aging a bit after such a long time of usage, the developments of new applications and devices, as demonstrated in the section on special applications, is vivid proof of the applicability and versatility of this simple but elegant calorimetric technique.
