Chemical historical development

An article in the December 1988 issue of the Journal of Chemical Education traces the historical development of Markovnikov s rule In that article Markovnikov s name is spelled Markow nikoff which is the way it appeared in his original pa per written in German...

The historical development of the electronic configuration model is traced and the status of the model with respect to quantum mechanics is examined. The successes and problems raised by the model are explored, particularly in chemical ah initio calculations. The relevance of these issues to whether chemistry has been reduced to quantum mechanics is discussed, as are some general notions on reduction. 

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.

The historical development and elementary operating principles of lasers are briefly summarized. An overview of the characteristics and capabilities of various lasers is provided. Selected applications of lasers to spectroscopic and dynamical problems in chemistry, as well as the role of lasers as effectors of chemical reactivity, are discussed. Studies from these laboratories concerning time-resolved resonance Raman spectroscopy of electronically excited states of metal polypyridine complexes are presented, exemplifying applications of modern laser techniques to problems in inorganic chemistry. 

An estimate for the lowest level of toxicological concern for human exposure to a chemical is developed by dividing the appropriate NOAEL by the uncertainty factor. Historically, this estimate has been termed the acceptable daily intake (or ADI) although it has been replaced by what EPA calls the reference dose (or RfD). Both ADIs and RfDs are expressed in terms of the amount of chemical exposure per amount of body weight per day. 

Efficiency gains can be boosted by integrating the various historically developed policies (chemicals, enviromnent, employee protection, product safety). This is especially apparent in the area of chemicals safety with the first step being a change in the communication and cooperation style of the national authorities. 

The purpose of this report is to review and present the important historical developments leading to the present understanding of the chemical nature of the poison including its chemical structure and properties, the mechanism causing death and the present means of control to make shellfish safer for human consumption. 

It follows that biomass will play a role complementary to other resources such as electricity from nuclear and hydraulic sources, as well as relatively inexhaustible supplies of natural gas, non-conventional oil and oil sands. The end use of these forms will be dictated by a combination of historic development and technological inertia such that substitution products electricity, methanol, hydrogen, or tonnage chemicals like ammonia, will provide the major outlets for biomass carbon...

A series of episodes in the historical development of our view of chemical atoms are presented. Emphasis is placed on the key observations that drove chemists and physicists to conclude that atoms were real objects and to envision their stracture and properties. The kinetic theory of gases and measmements of gas transport yielded good estimates for atomic size. The discovery of the electrorr, proton and neutron strongly irtfluenced discttssion of the constitution of atoms. The observation of a massive, dertse nucleus by alpha particle scattering and the measrrrement of the nuclear charge resrrlted in an enduring model of the nuclear atom. The role of optical spectroscopy in the development of a theory of electronic stracture is presented. The actors in this story were often well rewarded for their efforts to see the atoms. 

I have felt that in writing on this complex subject my primary duty hould be to present the theory of the chemical bond (from my point of view) in as straightforward a way as possible, relegating the historical development of the subject to a secondary place Many references are included to early work in this field the papers on the electronic theory of valence published during the last twenty years are so numerous, however, and often represent such small differences of opinion as to make the discussion of all of them unnecessary and even undesirable. 

Though gases are few in number—only about a hundred substances are gases at room temperature—their study was enormously important in the historical development of chemical theories. We ll look briefly at this historical development in the present chapter, and we ll see how the behavior of gases can be described.
