The SRM was adopted in 1950 by the American Society of Brewing Chemists which had recognized the need for an instrument based measurement of color unburdened by the difficulties of the Lovibond system which relies ( it is still in use in many industries including brewing-malts are often labeled with the Lovibond color of laboratory worts prepared from them ) on visual comparison of the sample to tinted glass discs.

Among his many honors are the Palladium Medal of the Electrochemical Society, the Gold Medal of the American Institute of Chemists, the Charles Lathrop Parsons Award, the Vannevar Bush Award and the National Medal of Science.

Chemists are exhaustively trying to measure the energy and thermodynamic properties of these non-covalent interactions found throughout supramolecular chemistry ; and by doing so hope to gain further insight into the combinatorial outcome of these many, small, non-covalent forces that are used to generate an overall effect on the supramolecular structure.

Recently Science Watch placed Sharpless and Valery V. Fokin within Top 10 list of its " Top 100 Chemists 2000-2010 " based on citations impact ; other faculty in the list were Carlos F. Barbas, M. G. Finn and John R. Yates.

Chemists Klaus Schmiegel and Bryan Molloy of Eli Lilly discovered the first SSRI, fluoxetine.

Chemists study the composition of matter and its properties such as density and acidity.

Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms.

Chemists carefully measure substance proportions, reaction rates, and other chemical properties.

Chemists use this knowledge to learn the composition, and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes.

Chemists may specialize in any number of subdisciplines of chemistry.

Chemists may belong to professional societies that specialize in chemist members, such as the Royal Society of Chemistry in the United Kingdom, or the American Chemical Society ( ACS ) in the United States.

Chemists may use standard enthalpies of formation for a reaction that is hypothetical.

Chemists would then characterize the molecular bonding of the solvent to the specific soil type, and biologists would study the impacts upon soil arthropods, plants, and ultimately pond-dwelling organisms that are the food of the endangered amphibian.

Jesse Boot, 1st Baron Trent ( 2 June 1850 – 13 June 1931 ) transformed The Boots Company, founded by his father, John Boot, into a national retailer, which branded itself as " Chemists to the Nation ", before he sold out his controlling interest to American investors in 1920.

The silence oppressed him, made him bend low over the horse's neck as if to hide from a wind that had begun to blow far away and was twisting slowly through the darkness in its slow search.

I had long since begun to lose my general innocence when I lost my trust in you, but this special innocence I lost before ever I loved, through my discovery that one could tremble with desire and even experience a flaming delight that had nothing, nothing whatever to do with friendship or liking, let alone with love.

Already Trevelyan had begun to parallel his nineteenth-century Italian studies with several works on English figures of the same period.

It is difficult to say what Thompson expected would come of their relationship, which had begun so soon after his emotions had been stirred by Maggie Brien, but when Katie wrote on April 11, 1900, to tell him that she was to be married to the Rev. Godfrey Burr, the vicar of Rushall in Staffordshire, the news evidently helped to deepen his discouragement over the failure of his hopes for a new volume of verse.
