  2. Theoretical chemistry - Wikipedia

    en.wikipedia.org/wiki/Theoretical_chemistry

    Jacobus van 't Hoff (1852–1911), an influential theoretical chemist and the first winner of the Nobel Prize in Chemistry.. Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular ...

  3. Systems chemistry - Wikipedia

    en.wikipedia.org/wiki/Systems_chemistry

    Systems chemistry is the science of studying networks of interacting molecules, to create new functions from a set (or library) of molecules with different hierarchical levels and emergent properties. [1] [2] Systems chemistry is also related to the origin of life (abiogenesis). [3]

  4. Chemical reaction network theory - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction_network...

    Chemical reaction network theory is an area of applied mathematics that attempts to model the behaviour of real-world chemical systems. Since its foundation in the 1960s, it has attracted a growing research community, mainly due to its applications in biochemistry and theoretical chemistry .

  5. J-aggregate - Wikipedia

    en.wikipedia.org/wiki/J-aggregate

    1,1’-diethyl-2,2’-cyanine chloride (pseudoisocyanine chloride, PIC chloride) Fiber-like J-aggregates (yellow) and light-guiding microcrystallites (red) A J-aggregate is a type of dye with an absorption band that shifts to a longer wavelength (bathochromic shift) of increasing sharpness (higher absorption coefficient) when it aggregates under the influence of a solvent or additive or ...

  6. Chemistry - Wikipedia

    en.wikipedia.org/wiki/Chemistry

    Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

  7. Synergetics (Haken) - Wikipedia

    en.wikipedia.org/wiki/Synergetics_(Haken)

    Synergetics is an interdisciplinary science explaining the formation and self-organization of patterns and structures in open systems far from thermodynamic equilibrium.It is founded by Hermann Haken, inspired by the laser theory.

  8. Cellular organizational structure - Wikipedia

    en.wikipedia.org/wiki/Cellular_organizational...

    A non-biological entity with a cellular organizational structure (also known as a cellular organization, cellular system, nodal organization, nodal structure, et cetera) is set up in such a way that it mimics how natural systems within biology work, with individual 'cells' or 'nodes' working somewhat independently to establish goals and tasks ...

  9. 3-j symbol - Wikipedia

    en.wikipedia.org/wiki/3-j_symbol

    For this, it is strongly related to the group representation theory of the groups SU(2) and SO(3) as discussed above. However, many other groups are of importance in physics and chemistry, and there has been much work on the symbol for these other groups. In this section, some of that work is considered.
