Technology issues

This concludes our discussion of novolac systems. We have covered only the most basic chemistry and formula strategies. To go further would lead us into technology issues that lie beyond the scope of this discussion and could go on indefinitely. The references provided will lead the interested reader more deeply into the subject.

Thus the study of surfaces has emerged as an important focus in the chemical sciences, and the relationship between surfaces of small systems and their performance has emerged as a major technological issue. Flow in microfluidic systems—for example, in micromechanical systems with potential problems of stiction (sticking and adhesion) and for chemistry on gene chips—depends on the properties of system surfaces. Complex heterogeneous phases with high surface areas—suspensions of colloids and liquid crystals—have developed substantial... 

Coherence and maintainability of the system degrade rapidly if different developers choose their own schemes to solve these technology issues. Large-scale performance and scalability are determined primarily by how the components are partitioned and distributed across machines and by the nature of communication across machines.

The production of 10 TW of nuclear power with the available nuclear fission technology will require the construction of a new 1 GWe nuclear fission plant every day for the next 50 years. If this level of deployment would be reached, the known terrestrial uranium resources will be depleted in 10 years [3], Breeder reactor technology should be developed and used. Fusion nuclear power could give an inexhaustible energy source, but currently no exploitable fusion technology is available and the related technological issues are extremely hard to solve. 

A proposal for the comprehensive study of chemical processes in a variety of important condensed-phase systems using modern theoretical methodology has been presented. The primary goals of the research are to provide microscopic information on the mechanisms and structural and dynamical properties of the chemical systems proposed for investigation, to test the applicability of modern ab initio molecular dynamics (MD) by comparison with experiment, and to develop and apply novel ab initio MD techniques in simulating complex chemical systems. The proposed research will contribute to the forefront of modern theoretical chemistry and address a number of important technological issues. The PI has carefully attempted to demonstrate his knowledge, ability, and resources to carry out the proposed research projects.

Unlike SiC, GaN is still not mature for the market. There is no doubt that the technological issues will be overcome but it will take some time. And finally, since money rules in the ruthless commercial world, will the manufacturing cost of GaN HEMTs be low enough to capture a lion s share or just a niche portion of the market ... 

Work on technological issues was more important and even dominating over that on basic aspects from the beginning of the 19th century brewing (Roberts et al., 1995), wine, bread and acetic acid production. These topics made up important parts of the chemical technology of the time (Poppe, 1842 Knapp, 1847 Wagner, 1857 Payen, 1874). Knapp considered scientific and practical, industrial interest as equally important. 

As pointed out in the beginning of the chapter—and perhaps also noticeable from the process description earlier—the pultrusion process at first appears rather simple and straightforward however, several intricacies arise on closer inspection. The key technology issues of pultrusion of thermoset-matrix composites are usually considered to be resin formulation, temperature control, material guidance, and die design (not in order of importance). It is typically the skill in these areas that distinguishes a successful pultruder from his hapless competitor. 

Processing and design problems related to the technology issues discussed in the previous sections are usually addressed through trial-and-error type experiments, no doubt with great... 

Even if all the chemistry and technology issues were solved, there would still be questions about the size of the equipment, nitrogen blanketing, and safety measures. 

The Resource Recovery Unit staff also provides direct technical assistance to industry, when requested, and can perform plant inspections, process reviews or just meet with plant inspections, process reviews or just meet with plant representatives to discuss regulatory or technological issues.
