The World Association of Theoretical and Computational Chemists ( WATOC ) is a scholarly association founded in 1982 " in order to encourage the development and application of theoretical methods " in chemistry, particularly quantum chemistry and computational chemistry.

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.

This institution is supervised by the " Peruvian council of chemistry " ( also known as " Peruvian Board of Chemists ") and it has the approval of IUPAC and its affiliates.

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

Chemists had begun to recognize that many natural resins and fibres were polymers, and Baekeland investigated the reactions of phenol and formaldehyde.

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 generally steered away from anything that did not seem to follow Dalton's laws of multiple proportions and the problem was considered the domain of a different science, metallurgy.

In 1973 Chemists Frank Sherwood Rowland and Mario Molina, then at the University of California, Irvine, began studying the impacts of CFCs in the Earth's atmosphere.

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 at the Los Alamos National Laboratory in the United States have developed a tantalum carbide-graphite composite material that is one of the hardest materials ever synthesized.

Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production.

Chemists called the ‘ force ’ that caused chemical reactions affinity, but it lacked a clear definition.

First published in 1925, and now published jointly on the web by the Society of Dyers and Colourists ( United Kingdom ) and the American Association of Textile Chemists and Colorists ( USA ), this index is recognized internationally as the authoritative reference on colorants.

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.

Even if one region has an absolute advantage as to the ratio of its outputs to inputs in every type of output, it may still specialize in the output in which it has a comparative advantage and thereby gain from trading with a region that lacks any absolute advantage but has a comparative advantage in producing something else.

Locksmiths may be commercial ( working out of a storefront ), mobile ( working out of a vehicle ), institutional ( employed by an institution ) or investigational ( forensic locksmiths ) or may specialize in one aspect of the skill, such as an automotive lock specialist, a master key system specialist or a safe technician.

Over time, this process can result in adaptations that specialize organisms for particular ecological niches and may eventually result in the emergence of new species.

Over time, this process can result in populations that specialize for particular ecological niches and may eventually result in the emergence of new species.

In some countries, e. g. USA and Germany, neurologists may specialize in clinical neurophysiology, the field responsible for EEG, nerve conduction studies, EMG and evoked potentials.

In large projects, people may specialize in only one role.

* Corn-Vendors may specialize in one type of corn or they could offer varieties between savory / salty and sweet corn.

A developer may specialize in a certain video game console, such as Nintendo's Wii, Microsoft's Xbox 360, Sony's PlayStation 3, or may develop for a variety of systems, including personal computers.

These vets may be involved in a general practice, treating animals of all types ; may be specialized in a specific group of animals such as companion animals, livestock, laboratory animals, zoo animals or horses ; or may specialize in a narrow medical discipline such as surgery, dermatology, laboratory animal medicine, or internal medicine.

MBA programs expose students to a variety of subjects, which students may choose to specialize in a particular area.

Others may specialize in technical surveillance counter-measures ( TSCM ), sometimes called electronic counter measures ( ECM ), which is the locating and dealing with unwanted forms of electronic surveillance ( for example, a bugged boardroom for industrial espionage purposes ).

Within each field, a business may specialize in a particular type of real estate, such as residential, commercial, or industrial property.

Hematologists may specialize further or have special interests, for example, in:

Fleas that specialize as parasites on specific mammals may use other mammals as hosts ; therefore humans are susceptible to the predation of more than one species of flea.

Some collectors may specialize in specific fields ( such as Nobel Prize winners ) or general topics ( military leaders participating in World War I ) or specific documents ( i. e., signers of the Charter of the United Nations ; signers of the U. S. Constitution ; signers of the Israeli Declaration of Independence ; signers of the Charter of the European Common Union ; signers of the World War II German or Japanese surrender documents ).

In large projects, people may specialize in only one role.

The saplings are usually obtained in bulk from industrial nurseries, which may specialize in selective breeding in order to produce fast growing disease-and pest-resistant strains.

Various schools of industrial design and / or product design may specialize in one of these aspects, ranging from pure art colleges ( product styling ) to mixed programs of engineering and design, to related disciplines like exhibit design and interior design, to schools where aesthetic design is almost completely subordinated to concerns of function and ergonomics of use ( the so-called functionalist school ).

Internists may also specialize in " allergy " and " immunology.
