  2. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    v. t. e. A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [ 1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.

  3. History of the telescope - Wikipedia

    en.wikipedia.org/wiki/History_of_the_telescope

    After devoting some time to the inquiry he found that by combining two lenses formed of different kinds of glass, he could make an achromatic lens where the effects of the unequal refractions of two colors of light (red and blue) was corrected. In 1733, he succeeded in constructing telescope lenses which exhibited much reduced chromatic aberration.

  4. Phase (matter) - Wikipedia

    en.wikipedia.org/wiki/Phase_(matter)

    v. t. e. In the physical sciences, a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water.

  5. Separatory funnel - Wikipedia

    en.wikipedia.org/wiki/Separatory_funnel

    A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate ( partition) the components of a mixture into two immiscible solvent phases of different densities. [ 1] Typically, one of the phases will be aqueous, and the ...

  6. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    The azeotrope is easily broken in a distillation set-up by using a liquid–liquid separator (a decanter) to separate the two liquid layers that are condensed overhead. Only one of the two liquid layers is refluxed to the distillation set-up. High boiling azeotropes, such as a 20 percent by weight mixture of hydrochloric acid in water, also ...

  7. Alembic - Wikipedia

    en.wikipedia.org/wiki/Alembic

    Alembic. An alembic (from Arabic: الإنبيق, romanized : al-inbīq, originating from Ancient Greek: ἄμβιξ, romanized : ambix, 'cup, beaker') [ 1][ 2][ 3] is an alchemical still consisting of two vessels connected by a tube, used for distillation of liquids.

  8. Ferrofluid - Wikipedia

    en.wikipedia.org/wiki/Ferrofluid

    Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [ 1] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ...

  9. History of fluid mechanics - Wikipedia

    en.wikipedia.org/wiki/History_of_fluid_mechanics

    The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
