  • Interesting fact: Coral (pro osteon) has molecular architecture and chemistry similar to human bone and so it can be used to replace bone grafts, helping bones heal faster. 150-200 pounds of it can sustain hundreds of graphs
    • Chemistry A treatise on chemistry.
    • Chemistry An application of chemical theory and method to the consideration of some particular subject; as, the chemistry of iron; the chemistry of indigo.
    • Chemistry That branch of science which treats of the composition of substances, and of the changes which they undergo in consequence of alterations in the constitution of the molecules, which depend upon variations of the number, kind, or mode of arrangement, of the constituent atoms. These atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained. Chemistry deals with the changes in the composition and constitution of molecules. See Atom Molecule.

  • Interesting fact: Marie and Irene Curie are the only mother and daughter to win Nobel prizes with their husbands. Marie and Pierre Curie won the Physics prize in 1903. Irene and Frederic Joliot-Curie won in 1935 for chemistry. Incidentally, Marie Curie also won the 1911 Nobel Prize for chemistry.
    • n chemistry The science of the composition of material things and the changes which they undergo in consequence of changes in their ultimate composition. It regards all substances as made up of atoms (see atom) which are indivisible and have certain unchanging properties. An elementary substance consists of groups of chemically united atoms of the same kind; a compound substance, of groups of chemically united atoms of two or more different kinds. All compound substances, and most elementary ones, consist of definite groups of chemically united atoms which are called molecules. Each molecule has exactly the same chemical composition and properties as the whole mass of the substance, and is the smallest mass into which the substance can be divided without losing its identity. The laws, causes, and effects of changes in the kind, and the number and arrangement, of atoms within the molecule are the subject-matter of the science. See chemical.
    • n chemistry Same as chemiatry.

In science:

The model deals with the chemistry of the immediate region (thermal cooling region) and the hydrodynamical cooling region of post shock described by Bertschinger & Chevalier (1985), Fox & Wood (1985) and Willacy & Cherchneff (1998).
HCN in the inner envelope of {chi} Cygni
We have considered shock chemistry at gas layers very close to the star.
HCN in the inner envelope of {chi} Cygni
The abundances at 2R⋆ may not be the exact values in the outflow because of uncertainties in the dust formation radius which halts the shock chemistry, but are indicative.
HCN in the inner envelope of {chi} Cygni
But, to come to the point of our interest, the shock chemistry is responsible for formation of species like HCN along with CO2 and CS close to the star.
HCN in the inner envelope of {chi} Cygni
On the basis of the chemistry we can claim that HCN is a direct result of the shock chemistry in the inner wind region that we have considered here and travels as a parent species through the envelope unaltered until it reaches the photo-dissociation regions in the outer wind.
HCN in the inner envelope of {chi} Cygni
This is the first observational verification of the theoretical claim that shock chemistry plays an active role in defining the chemical composition of the inner wind regions of Miras.
