Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration.
Crystallography is the branch of science devoted to the study of molecular and crystalline structure and properties. The word crystallography is derived from the Ancient Greek word κρύσταλλος, and γράφειν. In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming 2014 the International Year of Crystallography.
Rubidium is a chemical element; it has symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. Rubidium is the first alkali metal in the group to have a density higher than water. On Earth, natural rubidium comprises two isotopes: 72% is a stable isotope 85Rb, and 28% is slightly radioactive 87Rb, with a half-life of 48.8 billion years—more than three times as long as the estimated age of the universe.
Isotope analysis is the identification of isotopic signature, abundance of certain stable isotopes of chemical elements within organic and inorganic compounds. Isotopic analysis can be used to understand the flow of energy through a food web, to reconstruct past environmental and climatic conditions, to investigate human and animal diets, for food authentification, and a variety of other physical, geological, palaeontological and chemical processes. Stable isotope ratios are measured using mass spectrometry, which separates the different isotopes of an element on the basis of their mass-to-charge ratio.
A trace element is a chemical element of a minute quantity, a trace amount, especially used in referring to a micronutrient, but is also used to refer to minor elements in the composition of a rock, or other chemical substance.
Chemometrics is the science of extracting information from chemical systems by data-driven means. Chemometrics is inherently interdisciplinary, using methods frequently employed in core data-analytic disciplines such as multivariate statistics, applied mathematics, and computer science, in order to address problems in chemistry, biochemistry, medicine, biology and chemical engineering. In this way, it mirrors other interdisciplinary fields, such as psychometrics and econometrics.
Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. It should not be confused with green chemistry, which seeks to reduce potential pollution at its source. It can be defined as the study of the sources, reactions, transport, effects, and fates of chemical species in the air, soil, and water environments; and the effect of human activity and biological activity on these. Environmental chemistry is an interdisciplinary science that includes atmospheric, aquatic and soil chemistry, as well as heavily relying on analytical chemistry and being related to environmental and other areas of science.
Edmund ("Ted") John Bowen FRS was a British physical chemist.
Winterborne Kingston is a village and civil parish in the county of Dorset in southern England. It lies 7 miles south of the town of Blandford Forum and 2 mi (3 km) northeast of the large village of Bere Regis. It is situated in a winterbourne valley on the edge of the dip slope of the Dorset Downs. In the 2011 census the parish had 282 households and a population of 643. In 2001 it had a population of 613.
Humphry John Moule Bowen was a British botanist and chemist.
Wolvercote Cemetery is a cemetery in the parish of Wolvercote and district of Cutteslowe in Oxford, England. Its main entrance is on Banbury Road and it has a side entrance in Five Mile Drive. It has a funeral chapel, public toilets and a small amount of car parking. It was awarded plaques as a category winner of 'Cemetery of the Year' in 1999 and 2001.
Frank Albert Cotton FRS was an American chemist. He was the W.T. Doherty-Welch Foundation Chair and Distinguished Professor of Chemistry at Texas A&M University. He authored over 1600 scientific articles. Cotton was recognized for his research on the chemistry of the transition metals.
In 1957, the research organization of the Chemicals Department of E. I. du Pont de Nemours and Company was renamed Central Research Department, beginning the history of the premier scientific organization within DuPont and one of the foremost industrial laboratories devoted to basic science. Located primarily at the DuPont Experimental Station and Chestnut Run, in Wilmington, Delaware, it expanded to include laboratories in Geneva, Switzerland, Seoul, South Korea, Shanghai, China, and India (Hyderabad). In January, 2016 a major layoff marked the end of the organization.
Harden M. McConnell was an American physical chemist. His many awards included the National Medal of Science and the Wolf Prize, and he was elected to the National Academy of Science."
Jeffery W. Kelly is an American businessman and chemist who is on the faculty of the Scripps Research Institute in La Jolla, California.
In geochemistry, paleoclimatology, and paleoceanography δ13C is an isotopic signature, a measure of the ratio of the two stable isotopes of carbon—13C and 12C—reported in parts per thousand. The measure is also widely used in archaeology for the reconstruction of past diets, particularly to see if marine foods or certain types of plants were consumed.
