  2. Characterization (materials science) - Wikipedia

    en.wikipedia.org/wiki/Characterization...

    Characterization, when used in materials science, refers to the broad and general process by which a material's structure and properties are probed and measured. It is a fundamental process in the field of materials science, without which no scientific understanding of engineering materials could be ascertained.

  3. Chemical Probes Portal - Wikipedia

    en.wikipedia.org/wiki/Chemical_Probes_Portal

    The Chemical Probes Portal is an open, online resource whose purpose is to identify and make available high quality chemical probes for use in biological research and drug discovery. While chemical probes can be valuable tools to elucidate signal transduction pathways and to validate new drug targets , many of the probes that are in use are not ...

  4. Group-contribution method - Wikipedia

    en.wikipedia.org/wiki/Group-contribution_method

    The simplest form of a group-contribution method is the determination of a component property by summing up the group contributions : [] = +.This simple form assumes that the property (normal boiling point in the example) is strictly linearly dependent on the number of groups, and additionally no interaction between groups and molecules are assumed.

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

    en.wikipedia.org/wiki/Job_plot

    Within chemistry, a Job plot, otherwise known as the method of continuous variation or Job's method, is a method used in analytical chemistry to determine the stoichiometry of a binding event. The method is named after Paul Job and is also used in instrumental analysis and advanced chemical equilibrium texts and research articles.
