Magnetism and Magnetic Materials Historical Developments and Present Role in Industry... 

It is also important to realize that chemistry is not a static body of knowledge as defined by the contents of a textbook. Chemistry came from somewhere and is at present heading in various specific directions. It is a living self-stimulating discipline, and we have tried to transmit this sense of growth and excitement by reference to the historical development of the subject when appropriate. The chemistry of the elements is presented in a logical and academically consistent way but is interspersed with additional material which illuminates, exemplifies, extends or otherwise enhances the chemistry being discussed. 

Radiant heat transfer had historically been the biggest heat transfer mechanism for windows. Low-e materials were developed and have historically been used to control for heat transfer. An example of the popularity of using metals to reflect heat to control for radiant heat transfer is the thermos bottle. Applying that new technology to windows, and getting materials that normally would affect transparency of the product to remain visually neutral, was a huge advance to the industry. 

The historical development of chemically electrodes is briefly outlined. Following recent trends, the manufacturing of modified electrodes is reviewed with emphasis on the more recent methods of electrochemical polymerization and on new ion exchanging materials. Surface derivatized electrodes are not treated in detail. The catalysis of electrochemical reactions is treated from the view of theory and of practical application. Promising experimental results are given in detail. Finally, recent advances of chemically modified electrodes in sensor techniques and in the construction of molecular electronics are given. 

Arguments against this rather simple way of proceeding can be based on the fact that the histoiy of chemistiy is simplified too far in order to produce suitable teaching material. Scientific developments are ripped out of their historical context and sometimes rudely simplified. Other concepts, like the historical problem-centred...

To appreciate the rapid development of process technology, the progression of the IC industry must be considered first. (For summaries of the historical development of this field, see references 1 and 2.) A central theme in the IC industry is the simultaneous fabrication of hundreds of monolithic ICs (or chips) on a wafer (or slice) of silicon (or other material such as gallium arsenide), which is typically 100-150 mm in diameter and 0.75 mm thick. In silicon technology, chip areas generally range from a few square millimeters to over 100 mm2. A large number (often more than 100) of individual process steps, which are precisely controlled and carefully sequenced, are required for the fabrication. 

The answer to that question today is "Lots of people." The study of both natural and synthetic materials has changed so dramatically in the past few decades that some of the most exciting research in the chemical sciences is now taking place in the field of materials science. In some ways, one of the most surprising accomplishments in materials science has been reported in research on composites, possibly the oldest type of material used by humans for construction purposes. Scientists are beginning to learn that "boring" materials like stone and clay can be reformulated and reshaped in a variety of ways, often with the use of synthetic materials, to produce products with superior chemical and physical properties to those found in nature or those that people had historically developed. 

The historical development of alkyllithium-initiated polymerization of olefins and diolefins for the synthesis of elastomeric materials is of interest not only because of its scientific and technological significance but also because of the insight it provides into the thinking and methodology of polymer (elastomer) researchers. 

However, an encyclopaedia focusing on instruments, which includes material on chemical instruments and apparatus, was published in 1998. It incorporates 327 entries on a diverse range of historical items.4 Its strengths are its fairly comprehensive coverage and inclusion of more recent and complex instruments. Descriptions of the historical development of each item are necessarily short. Though it does not concentrate particularly on chemistry, there is some useful material to be found in a German volume of 37 essays, including a chapter on a subject rarely treated, industrial reaction vessels.5...
