High-tech engineering

Nonwovens are unique, innovative, indispensable, high-tech engineered fabrics made from fibres, and are used across a wide range of applications and products. Modem life would be literally impossible without them.

The payoff to society from greater attention to the surface and interfacial engineering of concrete is potentially immense high-tech concretes that will prolong the life of public works and reduce their maintenance costs as well as dramatic new applications for this old reliable material. 

FRESHMAN CHEMISTRY is arguably an important course, one that needs to be viewed as a contribution beyond a service level. It affords the opportunity to make the case, to many students of varied disciplines, of why chemistry is the central science and is responsible for virtually all of the high-tech developments they encounter or read about. The course should be a vehicle to attract more students to chemistry. More importantly, it should instill greater respect for and appreciation of chemistry by students who will not necessarily specialize in it. In our view, this function is particularly important for engineering students, as they will frequently use the basic ideas in freshman chemistry in their professional lives, yet they often wonder where the connection is while they are exposed to these ideas in the classroom. 

Connectors, switches, electric distributors, fuse boxes and other electric fittings need a subtle balance of electrical and mechanical properties, durability, cost and aesthetics. This broad field creates fierce competition not only between engineering thermoplastics and SMC/BMC for the main applications but also with polypropylene and polyethylene or PVC for the lower performance parts and, at the opposite end of the scale, with high-tech plastics such as polyetherketone, polyetherimide, liquid crystal polymers. .. For example, without claiming to be exhaustive ... 

Polyimides are engineering plastics used only for specialized and technical applications. The applications are always high-tech. The price and the difficulty of transformation limit the use of polyimides to well-targeted applications taking advantage of the high performance of these materials. 

PBI is an engineering plastic used only for specialized and high-tech applications. Consumption varies according to the country. It is mainly used in high-tech sectors aircraft and aerospace, semiconductor and vacuum industries, electricity and electronics. For example ... 

The research community of chemical engineering has a responsibility to address and to solve problems that bolster the health of the chemical and petroleum industries, as well as that of many emerging high-tech and environmental industries. Advances in Chemical Engineering has a responsibility to publish articles that would shorten the gap between research results found in primary journals on the one hand, and the stimulation of new research, the teaching of graduate courses, and the practice of engineering on the other hand. 

Future issues of Advances in Chemical Engineering will include articles in all the major subjects of support frontiers of mature areas, development of high-tech areas, protection of environment and health, and development of new engineering science concepts and tools. 

The market potential of such high-tech materials and engineering plastics is not quite clear. An essentially shorter time-to-market is to be expected with pharmaceutical (intermediate) products. Examples are dipeptides containing alpha-substituted amino acids [65] and d,l-phenylalanine [66]). 

Titanium metal is used as a structural material in many high-tech applications such as in jet engines. What is the specific heat of titanium in J/ (g °C) if it takes 89.7 J to raise the temperature of a 33.0 g block by 5.20°C What is the molar heat capacity of titanium in J/(mol °C) ... 

We read and hear a great deal about the drift of the chemical industry to cheaper wage zones such as China. The shift of standard product production into these regions is already a fact but, if the basic conditions are put in place for manufactured, high-tech, research-intensive chemicals such as liquid crystals, then the economic success of the chemical industry in Europe can be secured as the engine of innovation in other industries.
