  2. Polyphasic sleep - Wikipedia

    en.wikipedia.org/wiki/Polyphasic_sleep

    Biphasic (or diphasic, bifurcated, or bimodal) sleep refers to two periods, while polyphasic usually means more than two. [1] Segmented sleep and divided sleep may refer to polyphasic or biphasic sleep, but may also refer to interrupted sleep , where the sleep has one or several shorter periods of wakefulness, as was the norm for night sleep in ...

  3. Marangoni effect - Wikipedia

    en.wikipedia.org/wiki/Marangoni_effect

    The Marangoni effect (also called the Gibbs–Marangoni effect) is the mass transfer along an interface between two phases due to a gradient of the surface tension. In the case of temperature dependence, this phenomenon may be called thermo-capillary convection [1] or Bénard–Marangoni convection. [2]

  4. Double-slit experiment - Wikipedia

    en.wikipedia.org/wiki/Double-slit_experiment

    The experiment belongs to a general class of "double path" experiments, in which a wave is split into two separate waves (the wave is typically made of many photons and better referred to as a wave front, not to be confused with the wave properties of the individual photon) that later combine into a single wave.

  5. Wheeler's delayed-choice experiment - Wikipedia

    en.wikipedia.org/wiki/Wheeler's_delayed-choice...

    [2]: 184 Like the double-slit experiment, Wheeler's concept has two equivalent paths between a source and detector. Like the which-way versions of the double-slit, the experiment is run in two versions: one designed to detect wave interference and one designed to detect particles. The new ingredient in Wheeler's approach is a delayed-choice ...

  6. Interfacial polymerization - Wikipedia

    en.wikipedia.org/wiki/Interfacial_polymerization

    One phase is above the interface, and the other phase is below. Polymerization occurs where the two phases meet, at the interface. Interfacial polymerization is a type of step-growth polymerization in which polymerization occurs at the interface between two immiscible phases (generally two liquids), resulting in a polymer that is constrained to ...

  7. Diauxic growth - Wikipedia

    en.wikipedia.org/wiki/Diauxic_growth

    Jacques Monod discovered diauxic growth in 1941 during his experiments with Escherichia coli and Bacillus subtilis. While growing these bacteria on various combination of sugars during his doctoral thesis research, Monod observed that often two distinct growth phases are clearly visible in batch culture, as seen in Figure 1.

  8. Delayed-choice quantum eraser - Wikipedia

    en.wikipedia.org/wiki/Delayed-choice_quantum_eraser

    In the basic double-slit experiment, a beam of light (usually from a laser) is directed perpendicularly towards a wall pierced by two parallel slit apertures.If a detection screen (anything from a sheet of white paper to a CCD) is put on the other side of the double-slit wall (far enough for light from both slits to overlap), a pattern of light and dark fringes will be observed, a pattern that ...

  9. Aqueous two-phase system - Wikipedia

    en.wikipedia.org/wiki/Aqueous_two-phase_system

    It is a common observation that when oil and water are poured into the same container, they separate into two phases or layers, because they are immiscible.In general, aqueous (or water-based) solutions, being polar, are immiscible with non-polar organic solvents (cooking oil, chloroform, toluene, hexane etc.) and form a two-phase system.
