Technological need

The U.S. government, a primary sponsor of scientific and technological developments that fostered the computer and communications technologies needed by the on-line database industry, also sponsored database development projects, information usage studies, and combined computer database development—usage projects. The successors of some of these projects continue to be prominent and include DIALOG, MEDLINE, BRS, LEXIS, and the Chemical Abstracts Registry System. 

In the United States the Clean Coal Technology program was created to develop and demonstrate the technology needed to use coal in a more environmentally acceptable manner. Activities range from basic research and estabUshing integrated operation of new processes in pilot plants through demonstration with commercial-scale equipment. 

Functional dyes (1) of many types are important photochemical sensitizers for oxidation, polymerization, (polymer) degradation, isomerization, and photodynamic therapy. Often, dye stmctures from several classes of materials can fulfiH a similar technological need, and reviewing several dye stmctures... 

An excellent, accessible overview of what surface scientists do, the problems they address and how they link to technological needs is in a published lecture by a chemist, Somorjai (1998). He concisely sets out the function of numerous advanced instruments and techniques used by the surface scientist, all combined with UHV (LEED was merely the first), and exemplifies the kinds of physical chemical issues addressed - to pick just one example, the interactions of co-adsorbed species on a surface. He also introduces the concept of surface materials , ones in which the external or internal surfaces are the key to function. In this sense, a surface material is rather like a nanostructured material in the one case the material consists predominantly of surfaces, in the other case, of interfaces. 

A limited overview of the process chemistry used at these sites is presented. This paper will also attempt to bridge, at least partly, the gap between ongoing fundamental plutonium research and development and applied technology needs. We believe it is important to bridge this gap, since a continuous flow of knowledge about plutonium chemistry from academic and government laboratories to the plant is necessary and beneficial...

Phil Horwitz asked me to comment on what I saw as potential disadvantages of the various plutonium pyrochemical processes extolled by speakers in the Tuesday sessions. I, too, am a fan of pyrochemical techniques. I recognize that pyrochemical processes for Pu processing are just in their infancy - on batch plant-scale. To be truly useful, such processes need to be operated on a continuous basis. Scientists and engineers concerned with such technology need to develop equipment and procedures required to operate pyrochemical processes in a cost-effective, continuous manner."... 

With the increasing areal density, many problems in overcoat and surface technology need to be solved. The first... 

Food coloring is restricted by law to prevent misuse that may lead to deception of consumers related to reduced value or usability. For this purpose, the European Union implemented food colorant guidelines in 1994 based on the understanding that food coloration presents a technological need. While European Parliament and Council Directive 94/36/EC lists colors and their uses in food, the European Commission Directive 95/45/EC contains specific purity criteria for colors in foodstuffs, e.g., a maximal lead content of 20 ppm.

More than just intuition tells us how important materials are. In 1989 the National Research Council (NRC) prepared a report, Materials Science and Engineering for the 1990s (7) that examined in detail the impact of materials science on our national competitiveness. The NRC study surveyed eight major industries that together employed 7 million people in 1987 and had sales of more than 1.4 trillion. Additional millions of jobs in ancillary industries depend on the materials industry. Despite the very different needs for particular materials, the NRC survey also showed a remarkable consistency in generic and technological needs. Every industry surveyed expressed a clear need to produce new and traditional materials more economically and with a higher reproducibility and quality than is currently possible.

Various techniques have been introduced which still lack specific applications in polymer/additive analysis, but which may reasonably be expected to lead to significant contributions in the future. Examples are LC-QToFMS, LC-multi-API-MS, GC-ToFMS, Raman spectroscopy (to a minor extent), etc. Expectations for DIP-ToFMS [132], PTV-GC-ToFMS [133] and ASE are high. The advantages of SFC [134,135], on-line multidimensional chromatographic techniques [136,137] and laser-based methods for polymer/additive analysis appear to be more distant. Table 10.33 lists some innovative polymer/additive analysis protocols. As in all endeavours, the introduction of new technology needs a champion.

The SCR-NH3 is a continuous process for NO treatment and shows very efficient treatment efficiency. But this technology needs to put in the vehicle an additional tank for the urea storage. Moreover, this technology is constrained from an architectural point of view because two DOCs are necessary before and after the DeNO catalyst to hydrolyze urea and form ammonia and to prevent the NH3 release in the exhaust line. 

Fig. 2.7 Sensor production technologies needs a reliable and cost effective integration of technologies for the sensor element, the electronic data (pre) processing assembly.

As a result, the technology needed for industrialization of the country did not progress at all, and the country had to depend upon primitive agriculture, with its extremely low productivity. This prevented the accumulation of capital necessary to initiate production on a progressive scale.
