  2. Cohesion (chemistry) - Wikipedia

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

    Mercury exhibits more cohesion than adhesion with glass Rain water flux from a canopy. Among the forces that govern drop formation: cohesion, surface tension, Van der Waals force, Plateau–Rayleigh instability. Water, for example, is strongly cohesive as each molecule may make four hydrogen bonds to other water molecules in a tetrahedral ...

  3. Meniscus (liquid) - Wikipedia

    en.wikipedia.org/wiki/Meniscus_(liquid)

    A: The bottom of a concave meniscus. B: The top of a convex meniscus. In physics (particularly fluid statics), the meniscus (pl.: menisci, from Greek 'crescent') is the curve in the upper surface of a liquid close to the surface of the container or another object, produced by surface tension.

  4. Surface tension - Wikipedia

    en.wikipedia.org/wiki/Surface_tension

    Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.

    en.wikipedia.org/wiki/List_of_states_of_matter

    Strange matter: A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed. Quark matter: Hypothetical phases of matter whose degrees of freedom include quarks and gluons Color-glass condensate

  6. Adhesion - Wikipedia

    en.wikipedia.org/wiki/Adhesion

    These two energy quantities refer to the energy that is needed to cleave one species into two pieces while it is contained in a medium of the other species. Likewise for a three species system: γ 13 + γ 23 – γ 12 = W 12 + W 33 – W 13 – W 23 = W 132, where W 132 is the energy of cleaving species 1 from species 2 in a medium of species 3 ...

  7. Cell adhesion - Wikipedia

    en.wikipedia.org/wiki/Cell_adhesion

    Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...

  8. Active matter - Wikipedia

    en.wikipedia.org/wiki/Active_matter

    [5] [6] [7] Most examples of active matter are biological in origin and span all the scales of the living, from bacteria and self-organising bio-polymers such as microtubules and actin (both of which are part of the cytoskeleton of living cells), to schools of fish and flocks of birds.

  9. Biological thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Biological_thermodynamics

    Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy. The nonequilibrium thermodynamic state of living ...
