Chemical engineering emerged upon the development of unit operations, a fundamental concept of the discipline.

Also in the 2000s, My Chemical Romance released four concept albums, the most popular being Three Cheers for Sweet Revenge and The Black Parade.

She also completed guest vocals on My Chemical Romance's 2006 concept album The Black Parade, portraying “ Mother War ,” a dark conception of the main character's mother, in the song Mama.

After work by Johns Hopkins University in the 1950s there was a concept for Direct Injection Antipersonnel Chemical Biological Agent ( DIACBA ) where flechettes were grooved, hollow pointed, or otherwise milled to retain a quantity of chemical biological warfare agent to deliver through a ballistic wound.

After the war he was made Reader in Chemical Thermodynamics at Oxford where he experimented in the composition of fuel trying to find compounds which were resistant to freezing and less volatile, devising the concept of " toluene numbers "-now referred to as octane ratings.

The band would follow up strongly with 1998's The Chemical Wedding, a concept album with a darker feel, the album contained no ballads, but is equally praised along with Accident of Birth as a fan favorite, even jokingly called by some " The best Iron Maiden album since Seventh Son.

The Wagonaire roof design was inspired by Stevens ' 1959 Scimitar concept car built in Stuttgart Germany by Ruetter for the Olin Mathieson Chemical Corporation.

Corey formalized this concept in his book The Logic of Chemical Synthesis.

Building on this theory, the chemist Linus Pauling published in 1931 what some consider one of the most important papers in the history of chemistry: " On the Nature of the Chemical Bond ".

Building on this article, Pauling's 1939 textbook: On the Nature of the Chemical Bond would become what some have called the " Bible " of modern chemistry.

Chemical engineering is the branch of engineering that deals with physical science ( e. g., chemistry and physics ), and life sciences ( e. g., biology, microbiology and biochemistry ) with mathematics and economics, to the process of converting raw materials or chemicals into more useful or valuable forms.

According to chemistry historian Henry Leicester, the influential 1923 textbook Thermodynamics and the Free Energy of Chemical Reactions by Gilbert N. Lewis and Merle Randall led to the replacement of the term " affinity " by the term " free energy " in much of the English-speaking world.

Berzelius called Davy's 1806 Bakerian Lecture On Some Chemical Agencies of Electricity " one of the best memoirs which has ever enriched the theory of chemistry.

There is much sophisticated engineering and chemistry involved here, with iTi, Pixdro, Asahi Kasei, Merck, BASF, HC Starck, Hitachi Chemical and Frontier Carbon Corporation among the leaders.

* Chemical sciences-ORNL conducts both fundamental and applied research in a number of areas, including catalysis, surface science and interfacial chemistry ; molecular transformations and fuel chemistry ; heavy element chemistry and radioactive materials characterization ; aqueous solution chemistry and geochemistry ; mass spectrometry and laser spectroscopy ; separations chemistry ; materials chemistry including synthesis and characterization of polymers and other soft materials ; chemical biosciences ; and neutron science.

* Chemical oceanography, or marine chemistry, is the study of the chemistry of the ocean and its chemical interaction with the atmosphere ;

Scientists have been increasingly able to attribute the observed ozone depletion to the increase of man-made ( anthropogenic ) halogen compounds from CFCs by the use of complex chemistry transport models and their validation against observational data ( e. g. SLIMCAT, CLaMS — Chemical Lagrangian Model of the Stratosphere ).

The chemistry curriculum has been approved by the Committee on Professional Training of the American Chemical Society.

The words, with some variations, are used in the track Jerusalem on Bruce Dickinson's album The Chemical Wedding, which also includes lines from book two of Milton.

The late author Sheldon H. Harris in his book " Factories of Death: Japanese Biological Warfare, 1932-1945, and the American cover up " wrote that, The test program, could be part of Project AGILE or Project OCONUS which began in fall 1962 and which was funded at least through fiscal year 1963, was considered by the Chemical Corps to be “ an ambitious one .” The tests were designed to cover “ not only trials at sea, but Arctic and tropical environmental tests as well .” The tests, presumably, were conducted at what research officers designated, but did not name, “ satellite sites .” These sites were located both in the continental United States and in foreign countries.

The US military has specialized units, which can respond to a bioterrorism event ; among them are the US Marine Corp's Chemical Biological Incident Response Force and the U. S. Army's 20th Support Command ( CBRNE ), which can detect, identify, and neutralize threats, and decontaminate victims exposed to bioterror agents.

New additions to the campus include the Cahill Center for Astronomy and Astrophysics and the Walter and Leonore Annenberg Center for Information Science and Technology, which opened in 2009, and the Warren and Katherine Schlinger Laboratory for Chemistry and Chemical Engineering followed in March 2010.

Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.

Chemical reactions are described with chemical equations, which graphically present the starting materials, end products, and sometimes intermediate products and reaction conditions.

Chemical gradients are sensed through multiple transmembrane receptors, called methyl-accepting chemotaxis proteins ( MCPs ), which vary in the molecules that they detect.

Even in 2010, more than forty years after the U. S. ban, California condors which feed on sea lions at Big Sur which in turn feed in the Palos Verdes Shelf area of the Montrose Chemical Superfund site seemed to be having continued thin-shell problems.

Methane is part of a homologous series known as the alkane s, which contain single Chemical bond | bonds only.

However, recent research published in Environmental Science & Technology, a publication of the American Chemical Society, suggests that many cases of feline hyperthyroidism are associated with exposure to environmental contaminants called polybrominated diphenyl ethers ( PBDEs ), which are present in flame retardants in many household products, in particular, furniture and some electronic products.

Chemical deposition techniques include chemical vapor deposition (" CVD "), in which a stream of source gas reacts on the substrate to grow the material desired.

The soundtrack featured Get Ready-era Chemical Brothers-produced " Here to Stay ", which was released as a single.

He debated Drexler in an exchange of letters which were published in Chemical & Engineering News as a point-counterpoint feature.

In 1859, he founded the Chemical News, a science magazine which he edited for many years and conducted on much less formal lines than is usual with journals of scientific societies.

Other manufacturers of cyanoacrylate included Permabond Division of National Starch and Chemical, Inc., which was a subsidiary of Unilever.

* Chemical: A toxic chemical, such as poison gas or nerve gas, is dispersed, which is designed to injure or kill human beings.

The organization promotes and verifies the adherence to the Chemical Weapons Convention which prohibits of the use of chemical weapons and requires their destruction.

The first half of the 20th century saw the publication of two influential textbooks that soon came to be regarded as founding documents of chemical thermodynamics, both of which used and extended Gibbs's work in that field: these were Thermodynamics and the Free Energy of Chemical Processes ( 1923 ), by Gilbert N. Lewis and Merle Randall, and Modern Thermodynamics by the Methods of Willard Gibbs ( 1933 ), by Edward A. Guggenheim.

Chemical propulsion engines, with their limited rate of chemical reaction exhaust velocity ( which is in the range of 2-4. 5 km / s ), become exponentially ineffective ( see Tsiolkovsky equation ) to achieve high interplanetary speeds ( in the 20-70 km / s range, within the Solar System ).

Chemical weathering also releases readily water-soluble cations such as calcium, sodium and magnesium, which give basaltic areas a strong buffer capacity against acidification.

This type of warfare is distinct from Nuclear warfare and Biological warfare, which together make up NBC, the military acronym for Nuclear, Biological, and Chemical ( warfare or weapons ), all of which are considered " weapons of mass destruction " ( WMD ).
