The United States National Chemistry Olympiad (or USNCO) is a contest held by the American Chemical Society (ACS) used to select the four-student team that represents the United States at the International Chemistry Olympiad (IChO). Each local ACS section selects 10 students (or more for larger ACS sections) to take the USNCO National Exam. To ...
In 1874, a group of American chemists gathered at the Joseph Priestley House to mark the 100th anniversary of Priestley's discovery of oxygen.Although there was an American scientific society at that time (the American Association for the Advancement of Science, founded in 1848), the growth of chemistry in the U.S. prompted those assembled to consider founding a new society that would focus ...
"ACS Reagent Grade", is regarded as a gold standard measure and is in some cases required for use in chemical manufacturing, usually where stringent quality specifications and a purity of equal to or greater than 95% are required. [2] The American Chemical Society does not validate the purity of chemicals sold with this designation, but it ...
[1] [2] Some of the commonly used grades of purity include: ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the Reagent Chemicals publication, issued by the ACS. [3] [4] It is suitable for food and laboratory uses.
The List of American Chemical Society national awards attempts to include national awards, medals and prized offered by the American Chemical Society (ACS). The ACS national awards program began in 1922 with the establishment of the Priestley Medal, the highest award offered by the ACS. [ 1 ]
The R. B. Wetherill Laboratory of Chemistry at Purdue University in West Lafayette, Indiana, constructed between 1928 and 1955 to house the university's Department of Chemistry [73] Research in the area of flavor chemistry and advances in analytical chemistry conducted at the USDA - ARS Western Regional Research Center from the 1940s [ 74 ]
Chemistry education (or chemical education) is the study of teaching and learning chemistry. It is one subset of STEM education or discipline-based education research (DBER). [ 1 ] Topics in chemistry education include understanding how students learn chemistry and determining the most efficient methods to teach chemistry.
The Fischer indole synthesis is a chemical reaction that produces the aromatic heterocycle indole from a (substituted) phenylhydrazine and an aldehyde or ketone under acidic conditions. [1] [2] The reaction was discovered in 1883 by Emil Fischer. Today antimigraine drugs of the triptan class are often synthesized by this method. The Fischer ...
