British chemical technology

Improvement in the processing and vulcanized qualities of a range of systems have been reported over the past decades. Modification of natural rubber, due to work in the British Rubber Producers Research Association, yields some of the most striking applications of microgel. A detailed study at the MV Lomonosov Institute of Fine Chemical Technology, in Moscow, on the effect of microgels on mechanical properties of cis-polyisoprene and butadiene-styrene rubbers extensively illustrates the properties of blends from latex combination of microgel and conventional or linear systems.(31)... 

The ancient history of Indian chemical technology mostly concerns the production of small amounts of material in many different places. However, in the case of iron, as shown above, the ability to cast larger objects was not exceeded elsewhere in the world. Exports in early times included salt, sugar, and some metal products. Under the British during the nineteenth century, both a development of and a decline in industrial chemistry took place. Only after the departure of the British did the chemical industry reaUy begin to flourish in India. 

In the early stages of the war, the British examined their own chemical technology for battlefield use. They initially investigated tear agents also but later turned to more toxic chemicals. In January 1915, several chemists at Imperial College successfully demonstrated ethyl iodoacetate as a tear gas to the War Office by gassing a representative. 

For much of the nineteenth century, Britain was the largest and most dynamic industrial economy in the world. The size of the British economy and of the imperial British state created many employment opportunities for chemists. It is thus not perhaps surprising that Britain was one of the first countries to develop both a professional chemical community and chemical societies. Moreover, self-governing societies, be they learned, campaigning, professional or interest-based, played a prominent role within British, and particularly middle-class, society. By the First World War, British chemists operated in a dense institutional network in 1912, Official Chemical Appointments (OCA), the directory of chemical posts published by the British professional association of chemists, the Institute of Chemistry, listed 24 Societies and Institutions directly interested in the advancement of chemical science and technology . This complex social and professional world means that it makes little sense to discuss the demarcation of the British chemical community in terms of a single... 

The British chemical industry was the first major new-technology industry to be outcompeted by Germany. In fact, for well over a century this has been cited as the supreme example of industrial decline and rise. And although the same type of situation can be discussed with reference to other countries, particularly Belgium...

The terminology error invariably refers to the difference in the numerical values between a measured value and the true value. It has become universally accepted in methods of comparison that the percentage composition of a standard sample provided and certified by the National Institute of Standards and Technology (NIST) or the British Pharmacopoea Chemical Reference Substance (BPCRS) or the European Pharmacopoea...
