Future Development

Future work on suspension polymerization will be concerned with new products and with new processes. Much of the new work on recipes and product properties is material-specific and will continue to appear in the patent literature. The development of new processes requires further fundamental investigation. Improvements to existing processes need closer attention to ways in which reactors are operated. These should include the following aspects. 

Current developments in simulation techniques include multiple time step methods and more efficient polarizable models. Hardware developments that increase the power of affordable computers will continue to expand the size of the systems treated and the extent of exploring the configurations and dynamics, making the simulations more realistic. 

Beyond the purely classical treatments of these interfaces, where structural and dynamical events are probed, lie the most interesting systems to study systems in which reactions occur. Chemical reactions by their very nature usually require quantum mechanical treatments. Such studies may be purely quantum mechanical or mixed quantum/classical mechanical in nature. Because reactions occur in localized environments, classical treatments of much of the system can dramatically reduce simulation times. Some exploratory studies in this direction have been conducted, and the field is full of possibilities.

As ever, future developments can be predicted by looking at current requirements that are still not being met. The interfacing of open applications still needs to be made more efficient and easier to validate this is where future developments will focused. 

Systems already exist that provide true plant-level integration through the use of a object brokers. The ability of these systems to provide full integration in the future relies upon the development of suitable standard object broker interfaces to the large number of existing de facto standards that currently exist. It is, however, unlikely that specific interfaces will be written for many devices and systems that use less popular protocols. 

What is more likely (and is already happening in some systems) is that generic, configurable interfaces will be developed. These will provide toolkits which allow transactional-based interfaces to be developed in a configurable manner. 

Modern communications are much more transaction based (a trend developed in the commercial and business sector), and these are less suited to traditional control system interfaces. Control systems have traditionally operated on a real-time basis, polling for data on a routine basis or being interrupt driven by alarms and events. These traditional systems are not well suited to transactional-based communications, and the use of object broker interfaces will overcome some of these problems. The new object-oriented interfaces will again be easier to validate since the object broker interfaces will be configured rather than programmed and will use standard software blocks to build the interfaces. 

As well as support for existing de facto standards, the future will see development focus on the provision of interfaces for true standards which should finally emerge within the next few years. The ability to develop interfaces for new object models quickly will be especially important given the current paces of new developments. As such standards emerge, the OCS, the MBS, and the ERP market will largely be split into those systems which fully support such object-oriented interfaces and those that do not. Needless to say, those systems that do not will find it difficult to develop complete solutions and will lack functionality. 

While higher-activity catalysts are valuable, future improvements will likely focus more on selectivity improvements. Higher activity means less catalyst needs to be purchased, which is an infrequent, rather than continuous, investment. Selectivity improvements, in contrast, represent a reduction in the feed needed for a given amount of product, so that is a reduction in the feed needed for every day of operation. Since feedstock is often the largest contribution to product cost, selectivity improvements can be quite valuable. Unlike activity improvements, which may shrink the size of the isomerization reactor, better selectivity can reduce the size of all units in the system due to reduced feed and reduced recycle. In an existing unit, the effective throughput would increase. 

Precious metals (Section 14.4.2.1) are generally more expensive than the other catalyst components, so reduced metal content is an ongoing effort. This is more of an issue with EB isomerization catalysts since they have higher metal content than EB dealkylation catalysts. 

Greater cycle lengths are also on the horizon. Where one-year cycle lengths between regenerations were typical for the early generations of EB isomerization catalysts, customers now expect two-year life as a minimum, and the demand for 

Beyond the necessary improvement of performance described above, application-orientated developments currently being considered are focused on two types of specific aims, described in the following sections. 

Given the speed with which similarity searching has developed as a general approach to accessing databases of chemical structures, it is of interest to consider the future evolution of similarity-searching systems.

Nanotubes in polymer composites would serve to increase the stiffness, strength and toughness, and provide other properties such as electrical and thermal conductivity. Since, at present, nanotubes can be manufactured only at lengths up to the submillimetre scale (thereby falling into the short-fibre category), their dominant role in composites is likely to remain as matrix modifiers and providers of multifunctional attributes in the foreseeable future. However, once nanotubes can be efficiently assembled on a

Today in construction, only approximately 15% of the potential strength of CFRP strips is used. One important reason for this poor efficiency is that many strengthening tasks are controlled by stiffness, not strength. The focus of future developments should therefore be on better exploitation of the potential offered by CFRP composites and on a change to thermoplastic

A rich library of tracers exists for the dopamine Systran and perhaps also the serotonin system however, little or nothing currently exists for the assessment of many other neurotransmitter systems in the brain, some of whose receptors have been identified only recently. Pharmaceutical and biotechnology industries are major sources not only of new compounds that target these sites as candidate therapeutics but also of compounds that may serve as radiotracers to evaluate these sites and the effects of disease and treatment. The incentive and raw materials for continued development of functional imaging of the human bram will depend on the establishment of sustained collaborations between academic and government research centers and the pharmaceutical industry.

The growth of unsaturated polyesters will continue to be fueled by their versatility and their ability to provide cost-effective solutions to end-use requirements. Unsaturated polyester composites will continue to provide solutions to engineering demands for corrosion resistance, strength-to-weight and cost performance. Marine, transportation and construction opportunities currently identified and being developed will provide growth beyond the existing applications presented. Some examples are as follows  

In the marine industry, consortiums have demonstrated the viability of topside commercial ship construction using unsaturated polyester sandwich constructions and innovative joinery techniques. Large composite rudders for naval vessels have been produced and are currently completing life cycle testing. 

In the transportation industry, there is an ever increasing use in auto, truck and bus applications. The advent of the electric vehicle, which may demand vastly improved weight reduction over today s state-of-the-art vehicles, would be a natural extension of current unsaturated polyester resin technologies. 

New and promising composite pre-form technology which can be in situ molded with unsaturated polyester resins to further improve structure and performance have been demonstrated.

This survey of organic photochromic and thermochromic compounds focuses on the main families that are involved in existing commercial applications, such as variable optical transmission materials (ophthalmic glasses and lenses), or in potential uses such as optical storage (optical disks or memories). 

Some of the major developments involving photochromism will very likely utilize other phenomena, in conjunction with photochromism, resulting in useful applications. Some of the work discussed in the chapters of this book illustrate the concept of coupling photochromism with another phenomenon. For example, combining the photochromic electron transfer reaction of viologens with electrochemistry shows promise in the development of electronic applications (Chapter 9). 

The development of supramolecular systems involving a photochromic pigment and organic semi-conductor oligomers or polymers, is also of interest.

Results from these CP-MD calculations show that we in fact have a more complicated situation than dealing with simple hydrogen bond or ion-pair complex formation as methanol interacts with a zeolite acidic proton. Stich and coauthors conclude that the zeolite reactivity can be understood only by taking three factors into account simultaneously zeolite topology, sorbate loading, and dynamic effects. The examples above illustrate that the capabilities of modern modeling techniques will allow us to accept this challenge. 

Because of the continued development of both computer hardware and modeling software, it will be increasingly possible to use even more sophisticated models and methods for modeling of zeolites and related systems. The need to reduce the complexity of a system as much as possible will diminish, meaning, in general, that models used in the future can produce results that should be more comparable to experiment than is possible at this moment. Our 

We also expect that more studies will use MD and the Car-Parrinello approach, while the share of studies based solely on energy minimization and cluster approximations will diminish. It seems reasonable to expect that some of the difficulties encountered with embedding will be solved in the next couple of years. If this becomes true, one might expect that embedding, in fierce competition with the Car-Parrinello approach, will be used extensively in studies on zeolite catalysis. For embedding to become a success, it will be necessary to develop force fields that are compatible with the quantum chemistry model that is used in the description of the catalytic site. Such a compatibility seems possible only if these force fields allow for polarization. 

One might hope that some progress would also be made in areas barely touched upon at all in zeolite modeling at this time. Specifically we think here of synthesis of zeolites and by zeolites, and of zeolite design. Ideally, one would like to model zeolite synthesis by MD simulation however, the time scale of zeolite synthesis, hours to many days, and the complexity of the synthesis mixture represent huge difficulties. Perhaps MC methods, for example, the configurational bias MC method, might be a way out let us wait and see.

Legislation concerned with the assessment and control of chemicals is varied and complex and has resulted in a piecemeal development of the regulatory process. 

Positive Approvals. Certain product groups are required to meet demanding approval regimes. These include  

The basis for health and safety law in the United Kingdom is provided under the Health and Safety at Work Act 1974 (HSWA), which sets out the general duties that employers have to their employees, and members of the public, and that employees have to themselves and each other. The legislation helps to fulfil wider European requirements for health and safety and places a general duty on manufacturers to ensure that substances are safe when properly used and to carry out such tests as are necessary. 

The Chemicals (Hazardous Information and Packaging for Supply) Regulations (CHIP) that were enacted in 1993 under the HSWA, together with subsequent amendments, are concerned with the supply of dangerous substances and preparations and sets out how these should be classified, labelled and packaged. There is also a requirement on the supplier to provide safety data sheets. 

The Control of Substances Hazardous to Health Regulations 1994 (COSHH) are set out under the HSWA and protect workers against risk to health from exposure to substances in the workplace. A risk assessment is required and must be made available to workers, with training given to those who might be exposed to such substances. The HSE is the competent authority for CHIP and COSHH in the United Kingdom.

The ammoxidation of methyl aromatic and heteroaromatic compounds is a convenient route to many nitriles required for further synthesis of fine chemicals. For example, for the production of amines by hydrogenation or of carboxylic acids and amides by hydrolysis. 

For further extension of the scope of the ammoxidation reaction new catalytic systems (based on detailed mechanistic knowledge) must be developed to establish more selective reactions, e. g. at lower temperature or under shape-selective conditions. For extension of application, effective protection of side-chains in the educts are also necessary. Finally, the search for more selective catalysts

There are still many unsolved problems in computational chemistry and, as discussed, many of them are not new. We still need a method for the quick and accurate calculation of free energies, and we need to understand the limits on the accuracy of any predictive methods. More broadly, what confidence limits can we put on any given prediction from any given level of theory For virtual screening, what are the most important terms left out of the standard docking functions, and indeed higher simulation methods Can we imagine a set of widely accepted well-validated model systems and benchmarks, both for experiment and theory  

In the coming years, excitons in disordered systems and strongly-coupled excitons will be a focus of attention. In mixed crystals consisting of two components, the guest molecules can be included into the exciton band of the host, i.e. amalgamated. The influence of such an amalgamation on the electrical, optical, and mag-nehc properties of the mixed crystals is an interesting, old, but still current research topic in the physics of molecular crystals [43]. 

At the end of this chapter on optical spectra, we must emphasize once again that we have limited ourselves here to a small selection out of the extensive area of organic crystals. Molecules with tt-electron systems and their lowest electronic excited states are the most important topics in current research and for applications, and they are the subject of the greatest interest at present.

The trend in mass spectrometry is currently clearly toward higher resolution and faster data acquisition. 

Probably, in future, resolution of about 100 000 and data rates of 20-40 Hz can be achieved with TOF-MS. With Orbitrap-MS, it is assumed that resolutions of more than 800 000 will be possible by more precise production of the cell and electronic devices. This would make it possible to reduce the scanning speed and then to realize the coupling with UHPLC also with good mass resolution. 

By connecting an ion mobility spectrometry (IMS) in front of a QTOF-MS, another dimension of separation is realized. Unseparated isobaric compounds, which have the same m/z value, can be separated after ionization by the structure-dependent drift time through the IMS. The combination of IMS with QTOF is also a powerful tool for nontarget analysis in complex samples, due to the fact that the chemical noise is drastically reduced by IMS. 

Another focus in future developments will be the optimization of ion sources with respect to ion generation and ion transport at different flows, which are used in nano- and micro-HPLC, LCxLC, and SFC to increase the sensitivity.

Readers are referred to the comprehensive treatise by Gordon Steel (1) for the basic theory of growing cell populations and a detailed review of cell kinetics in experimental systems and human tumours. Cell kinetics is essentially the quantitation of rates of ceU production and cell loss, which balance the overall rate of growth of cells, tissues, and tumours. This can vary from the simple concept of exponential growth for cells in culture to the complex growth characteristics of human tumours. The cell cycle drives cell production and its duration (Tc) is defined as the time interval within which a cell completes a mitotic cycle.

Applying the language to designing circuits that may be s)mthesized is 

The microelectronics industry is a fast-moving industry and a number of developments are likely to take place in the next 5 years. Technology will continue to improve. Device feature sizes will continue to shrink. In itself this will continue to bring the increased packing density per chip, the improvement in dock speed and the improvement in power consumed per transistor. Concurrently, the problems of testability of such tightly integrated systems and the over power consumption per device will continue to pose problems. However, in addition to these problems, a new one will be faced that may pose substantially new problems for the designers of synthesis tools. 

Down to 1 jiim feature size, the delays in the circuit are primarily caused by the switching speed of the gate and the capacitance associated with the gates. However, as flie transistors shrink in size, their switching speed improves, but the resistance of the interconnect gets relatively worse. As feature sizes move towards 0.1 i, the majority of the delay in a system is due to interconnect delay. 

For synthesis tools, the above developments turn the principles of effective and efficient synthesis upside down. Previously, s)mthesis tools concentrated on the design of small and fast blocks of logic, which are connected together via wires. In contrast, future s)mthesis tools are likely to need to construct small and fast blocks of interconnection and attach blocks of logic to these networks. Conceptually, this introduces the issues of physical location as a design parameter, whereas previously synthesis was concerned almost primarily with logic minimization and critical path reduction. 

Synthesis tools for deep submicron design (less than 0.3 pp.) will have to deal much more with the issue of timing. They will need to partition designs and allocate design resources (in this case wires as much as gates) on the basis of reducing physical distance between components. 

Tomorrow (even today), the quest will be to pack the highest amount of bond energy into the final ceramic compound and to impart a high degree of 

Hopefully the first generation of gravitational detectors will allow the first direct detection of gravitational waves. To build the field of gravitational astronomy, further improvements in sensitivity are needed. A vigorous research and development program is being carried out for both interferometers and bars in attempts to approach the fundamental SQL.

The possible improvements in sensitivity of the LIGO detector are shown in Fig. 9. 

Although many possibilities have been explored to lower the production cost of PHA, they are still not in a position to challenge the conventional plastics such as polypropylene and polystyrene that cost only l/kg. The success of transgenic plants that produce large quantities of PHA could eventually lower the cost of PHA to a level comparable to conventional plastics. To achieve this goal, much research work is still needed to improve PHA genetic expression levels in economically interesting plants, such as oilseeds and potatoes. 

In addition to the application as plastics, PHA can also be a potential source of chiral hydroxy acid feedstock for the fine chemical industry. In contrast to the introduction of new polymers, the PHA hydroxy acids and the related derivatives can be readily integrated into existing fine chemical markets. 

The long-term development for PHAs will be a promising subject for research which has the potential to be profitable to many industries. Collaboration between microbiologists, molecular biologists, polymer scientists, material scientists and industry is the key for PHA exploration. Many new developments should be expected in the new century.

The reservoir model will usually be a computer based simulation model, such as the 3D model described in Section 8. As production continues, the monitoring programme generates a data base containing information on the performance of the field. The reservoir model is used to check whether the initial assumptions and description of the reservoir were correct. Where inconsistencies between the predicted and observed behaviour occur, the model is reviewed and adjusted until a new match (a so-called history match ) is achieved. The updated model is then used to predict future performance of the field, and as such is a very useful tool for generating production forecasts. In addition, the model is used to predict the outcome of alternative future development plans. The criterion used for selection is typically profitability (or any other stated objective of the operating company). 

The following sections cover the design goals, decisions, and outcomes of the first two major versions of NAMD and present directions for future development. It is assumed that the reader has been exposed to the basics of molecular dynamics [2, 3, 4] and parallel computing [5]. Additional information on NAMD is available electronically [6].

Dry dense medium (pneumatic fluidized-bed) separation has been used, but has not received wide attention by the industry. An area of promise for future development is the use of magnetically stabilized dense medium beds by using ferro or magnetic fluids (2,10). Laboratory and pilot-scale units such as Magstream are available. In this unit, material is fed into a rotating column of water-based magnetic fluid. Particles experience centtifugal forces and... 

Future Developments. The most recent advance in detergent alkylation is the development of a soHd catalyst system. UOP and Compania Espanola de Petroleos SA (CEPSA) have disclosed the joint development of a fixed-bed heterogeneous aromatic alkylation catalyst system for the production of LAB. Petresa, a subsidiary of CEPSA, has announced plans for the constmction of a 75,000 t/yr LAB plant in Quebec, Canada, that will use the UOP / -paraffin dehydrogenation process and the new fixed-bed alkylation process (85). 

In dealing with future uncertainties. Royal Dutch/SheU pioneered Scenario planning (54,55). Alternative assumptions for future developments can be combined under this approach in various ways to give a number of consistent possible outcomes (56) and provide a basis for both actions and reactions. The approach has rewarded Shell handsomely. 

Future developments are likely to feature the production of more siUcone sealants that do not pick up dirt, more latex acryUc sealants that have high performance properties, urethanes that have improved uv stabiUty, and high performance polysulfides that are made in the United States. 

Future development of SAM-based analytical technology requires expansion of the size and shape selectivity of template stmctures, as well as introduction of advanced chemical and optical gating mechanisms. An important contribution of SAMs is in miniaturization of analytical instmmentation. This use may in turn have considerable importance in the biomedical analytical area, where miniature analytical probes will be introduced into the body and target-specific organs or even cell clusters. Advances in high resolution spatial patterning of SAMs open the way for such technologies (268,352). 

Continuing the current trend, there will be an even greater need to provide highly effective dispersants with minimum environmental impact. Future development efforts will focus on improved performance at low dosage to further reduce the environmental load, accountability (ability to detect... 

As none of the above have been able to dominate the industry, it is quite possible that future developments will provide a superior approach for implementing sequence logic. 

Solid-wa.ste-filling plan. The specific method of filling will depend on the characteristics of the site, such as the amount of available cover material, the topography, and local hydrology and geology. To assess future development plans, it will be necessary to prepare a detailed plan for the layout of the individual solid-waste cells. On the basis of the characteristics of the site or the method of operation (e.g., gas recovery), it may be necessaiy to incorporate special features for the control of the movement of gases and leachate from the landfill. 

In the last chapter we saw how a basic knowledge of the mechanisms of creep was an important aid to the development of materials with good creep properties. An impressive example is in the development of materials for the high-pressure stage of a modern aircraft gas turbine. Here we examine the properties such materials must have, the way in which the present generation of materials has evolved, and the likely direction of their future development.

SIMS is one of the most powerful surface and microanalytical techniques for materials characterization. It is primarily used in the analysis of semiconductors, as well as for metallurgical, and geological materials. The advent of a growing number of standards for SIMS has gready enhanced the quantitative accuracy and reliability of the technique in these areas. Future development is expected in the area of small spot analysis, implementation of post-sputtering ionization to SIMS (see the articles on SALI and SNMS), and newer areas of application, such as ceramics, polymers, and biological and pharmaceutical materials. 

Whilst the development of flame retarders has in the past been largely based on a systematic trial-and-error basis, future developments will depend more and more on a fuller understanding of the processes of polymer combustion. This is a complex process but a number of stages are now generally recognised and were discussed in Chapter 5. 

We hope this book will contribute to the dissemination of present understanding of the subjeet and to future developments in the seienee and technology of carbon nanotubes and fullerenes, and of carbon science more generally. 

For mechanical wave measurements, notice should be taken of the advances in technology. It is particularly notable that the major advances in materials description have not resulted so much from improved resolution in measurement of displacement and/or time, but in direct measurements of the derivative functions of acceleration, stress rate, and density rate as called for in the theory of structured wave propagation. Future developments, such as can be anticipated with piezoelectric polymers, in which direct measurements are made of rate-of-change of stress or particle velocity should lead to the observation of recognized mechanical effects in more detail, and perhaps the identification of new mechanical phenomena.

Because it is usually very difficult to evaluate beforehand the conditions which may induce an initial blast, a conservative approach is to apply an initial blast strength of 10 to the fuel-air charge blast model. This model, however, offers possibilities for future development. 

The case study described here concerns a human factors audit of a computer controlled process system which was being introduced in a distillation imit of a chemical plant. The unit was in transition from replacing its pneumatic panel instrumentation with the new system. However, control had not yet been transferred and the staff were still using the panel instrumentation. The role of the project was to evaluate a preliminary design of the computer-based display system and provide recommendations for future development.
