Driving Forces Behind Development

The development drivers for alternative anti-corrosion coatings should be evident from tlie above discussion. They address the following a) The issue of cracks and

The driving force behind development of more selective sorbents is minimizing the problem of coextracting matrix interferences that are usually present in much greater concentration than the trace levels of the analyte of interest. More selective sorbents also permit extraction of larger sample volumes, thereby reducing the level of detection of the analyte of interest. 

Ease of use and analytical speed have been the driving force behind development in this field. The most commonly used technique today is closed digestion under pressure using HNO3, alone or in combination with H202. Vessels of plastic or glass/quarts contained in stainless steel cylinders (the so-called bombs) are often used and heated in an autoclave or some other heating device. A drawback with steel bombs is that they cool down slowly. 

It is very time consuming and very expensive to invent, develop, and produce a new polymer in a new plant (total cost > 100 million). A new polymer blend, in contrast, will be less expensive to invent Also, it will take less time to develop and will require low investment funding to produce or, if available, it could be produced in existing equipment Blend composition can be optimized to meet specific end-use property requirements. The driving force behind development of these novel compositions is the economics, property attributes, ease of manufacture of the... 

Two engines are under development as of this writing the two-stroke engine and the lean bum engine. The driving forces behind this development are fuel economy and global warming (see ATMOSPHERIC MODELS). 

Other Titles - The Clean Air Act Amendments of 1990 continue the federal acid rain research program and contain several provisions relating to research, development and air monitoring. They also contain provisions to provide additional unemployment benefits through the Job Training Partnership Act to workers laid off as a consequence of compliance with the Clean Air Act. The Act also contains provisions to improve visibility near National Parks and other parts of the country. Strict enforcement of the Clean Air Act Amendments is the driving force behind pollution abatement. Non-compliance is simply not an option, since there are both financial and criminal liabilities that outweigh any benefits derived from a business. 

Classical gels had a low degree of cross-linkage and were of a large particle size. This resulted in that modest flow rates could only be applied and the separation time was typically 10 hr, which at that time was perfectly acceptable, keeping in mind that preparation of the column could take up to 2 days or more. After the introduction of Sephadex, new materials have been introduced continuously on the market, and still, 30 years after the introduction of the first commercial material, new media are still introduced, also from the originators of Sephadex. What are the driving forces behind this development and what are the features of these new media ... 

The initial driving force behind the development of HPCE came from the need of better and faster separations for biologically important molecules used in biotechnology research and in the biopharmaceutical industry. Traditional electrophoresis is an established method in life sciences however,... 

Heteroatom transfer in metallacyclopentadienes was first developed in the context of cobalt chemistry in the mid-1970s [27]. Cobaltacyclopentadienes were converted into various five-membered heterocyclic compounds such as pyrrole and thiophene, and into six-mem-bered heterocyclic compounds such as pyridine and pyridone derivatives. In the case of zirconacydopentadienes, the heteroatom compound must bear at least two halide substituents, since the Cp2Zr moiety is re-converted to the stable Cp2ZrX2. Indeed, this is the driving force behind the heteroatom transfer of zirconacydopentadienes. 

A vital question which remains unanswered, however, is precisely what sort of larger problems quantum chemical research should address. Historically the field has primarily dealt with problems associated with molecular spectroscopy, the methylene problem being a classic example. [4] As a result, the driving force behind nearly all methodological development in quantum chemistry has been applications involving small molecules (fewer than twenty atoms) of rather limited interest to other areas of chemistry or biochemistry. We are currently enjoying a period of symbiotic collaboration between experimentalists and quantum chemists where the fun-...
