  2. Ionic liquid - Wikipedia

    en.wikipedia.org/wiki/Ionic_liquid

    Low-temperature ionic liquids can be compared to ionic solutions, liquids that contain both ions and neutral molecules, and in particular to the so-called deep eutectic solvents, mixtures of ionic and non-ionic solid substances which have much lower melting points than the pure compounds. Certain mixtures of nitrate salts can have melting ...

  3. Ioliomics - Wikipedia

    en.wikipedia.org/wiki/Ioliomics

    Ioliomics (from a portmanteau of ions and liquids) is the study of ions in liquids (or liquid phases) and stipulated with fundamental differences of ionic interactions. [1] Ioliomics covers a broad research area concerning structure, properties and applications of ions involved in various biological and chemical systems.

  4. Deep eutectic solvent - Wikipedia

    en.wikipedia.org/wiki/Deep_eutectic_solvent

    Deep eutectic solvents or DESs are solutions of Lewis or Brønsted acids and bases which form a eutectic mixture. [1] Deep eutectic solvents are highly tunable through varying the structure or relative ratio of parent components and thus have a wide variety of potential applications including catalytic, separation, and electrochemical processes.

  5. Protic ionic liquid - Wikipedia

    en.wikipedia.org/wiki/Protic_ionic_liquid

    A protic ionic liquid is an ionic liquid that is formed via proton transfer from a Brønsted acid to a Brønsted base. [1] Unlike many other types of ionic liquids, which are formed through a series of synthesis steps, [ 2 ] protic ionic liquids are easier to create because the acid and base must simply be mixed together.

  6. Wetting solution - Wikipedia

    en.wikipedia.org/wiki/Wetting_solution

    A typical wetting solution molecule consists of a hydrophilic head and long hydrophobic tail. (From top to bottom: non-ionic, anionic, cationic and zwitterionic.) Wetting solutions are liquids containing active chemical compounds that minimise the distance between two immiscible phases by lowering the surface tension to induce

  7. Hofmeister series - Wikipedia

    en.wikipedia.org/wiki/Hofmeister_series

    The denaturing of proteins by an aqueous solution containing many types of ions is more complicated as all the ions can act, according to their Hofmeister activity, i.e., a fractional number specifying the position of the ion in the series (given previously) in terms of its relative efficiency in denaturing a reference protein.

  8. Pitzer equations - Wikipedia

    en.wikipedia.org/wiki/Pitzer_equations

    They can be used to calculate mixed ion activity coefficients and water activities in solutions of high ionic strength for which the Debye–Hückel theory is no longer adequate. They are more rigorous than the equations of specific ion interaction theory (SIT theory), but Pitzer parameters are more difficult to determine experimentally than ...

  9. Water model - Wikipedia

    en.wikipedia.org/wiki/Water_model

    In computational chemistry, a water model is used to simulate and thermodynamically calculate water clusters, liquid water, and aqueous solutions with explicit solvent. The models are determined from quantum mechanics, molecular mechanics, experimental results, and these combinations. To imitate a specific nature of molecules, many types of ...
