History, Chemistry, and a Longer View

A History of Chemistry

These contained the story from the Renaissance to the present day-an account fuller in detail, documentation, new views and finds than anything that had gone before. They were published during the author's lifetime and enjoyed the meticulous care which he was wont to apply to proofreading and correcting of errata. Five years have elapsed since his death in October 1965 and we are happy and grat...

Equol: history, chemistry, and formation.

Equol, first isolated from equine urine in 1932 and identified 50 years later in human urine as a metabolite of the soy isoflavones, daidzin and daidzein, is produced by intestinal bacteria in some, but not all, adults. This observation led to the term equol-producers to define those adults that could make equol in response to consuming soy isoflavones and the hypothesis that the health benefit...

Silicone Biomaterials: History and Chemistry

History of clinical chemistry

wet-nursing in England appears to be in the seventeenth century when the urban growth of London in particular presented mothers with similar problems regarding their infants. Evidence for bureaucratic intervention, however, is lacking in England. The conclusion of the author that economic pressure was the predominant cause in the rise and decline of wet-nursing is convincing. The sheer intensit...

A Post-buckminsterfullerene View of Carbon Chemistry

Closed-cage all-carbon molecules referred to as fullerenes were discovered in carbon vapor from laser heating of graphite and subsequently produced in macroscopic quantities by resistive heating of carbon rods. Suggestions that fullerenes may be involved in soot formation, and the detection, in flames, of all-carbon ions having the same masses as fullerenes, have generated much interest in the ...
