  2. Reduced derivative - Wikipedia

    en.wikipedia.org/wiki/Reduced_derivative

    In mathematics, the reduced derivative is a generalization of the notion of derivative that is well-suited to the study of functions of bounded variation. Although functions of bounded variation have derivatives in the sense of Radon measures, it is desirable to have a derivative that takes values in the same space as the functions themselves ...

  3. Green chemistry - Wikipedia

    en.wikipedia.org/wiki/Green_chemistry

    More broadly, the idea of green chemistry can easily be linked (or confused) with related concepts like green engineering, environmental design, or sustainability in general. Green chemistry's complexity and multifaceted nature makes it difficult to devise clear and simple metrics. As a result, "what is green" is often open to debate. [44]

  4. Reductive amination - Wikipedia

    en.wikipedia.org/wiki/Reductive_amination

    It is a common method to make amines and is widely used in green chemistry since it can be done catalytically in one-pot under mild conditions. In biochemistry, dehydrogenase enzymes use reductive amination to produce the amino acid glutamate. Additionally, there is ongoing research on alternative synthesis mechanisms with various metal ...

  5. Derivatization - Wikipedia

    en.wikipedia.org/wiki/Derivatization

    Derivatization is a technique used in chemistry which converts a chemical compound into a product (the reaction's derivate) of similar chemical structure, called a derivative. Generally, a specific functional group of the compound participates in the derivatization reaction and transforms the educt to a derivate of deviating reactivity ...

  6. Material derivative - Wikipedia

    en.wikipedia.org/wiki/Material_derivative

    An example of this case is a swimmer standing still and sensing temperature change in a lake early in the morning: the water gradually becomes warmer due to heating from the sun. In which case the term ∂ φ / ∂ t {\displaystyle {\partial \varphi }/{\partial t}} is sufficient to describe the rate of change of temperature.

  7. Green solvent - Wikipedia

    en.wikipedia.org/wiki/Green_solvent

    Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry. They came to prominence in 2015, when the UN defined a new sustainability -focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future. [ 1 ]

  8. Derivative (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Derivative_(chemistry)

    In chemistry, a derivative is a compound that is derived from a similar compound by a chemical reaction.. In the past, derivative also meant a compound that can be imagined to arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms, [1] but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity.

  9. Differential calculus - Wikipedia

    en.wikipedia.org/wiki/Differential_calculus

    In operations research, derivatives determine the most efficient ways to transport materials and design factories. Derivatives are frequently used to find the maxima and minima of a function. Equations involving derivatives are called differential equations and are fundamental in describing natural phenomena.
