  2. Wood glue - Wikipedia

    en.wikipedia.org/wiki/Wood_glue

    Wood glue is an adhesive used to tightly bond pieces of wood together. Many substances have been used as glues. Many substances have been used as glues. Traditionally animal proteins like casein from milk or collagen from animal hides and bones were boiled down to make early glues.

  3. Pykrete - Wikipedia

    en.wikipedia.org/wiki/Pykrete

    However, it was constructed using plain ice (from the lake), before pykrete was proposed. It took slightly more than an entire summer to melt, but plain ice proved to be too weak. Pyke learned from a report by Herman Mark and his assistant that ice made from water mixed with wood fibres formed a strong solid mass—much stronger than pure water ...

  4. Table of specific heat capacities - Wikipedia

    en.wikipedia.org/wiki/Table_of_specific_heat...

    Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...

  5. Ice rules - Wikipedia

    en.wikipedia.org/wiki/Ice_rules

    In 1935, Linus Pauling used the ice rules to calculate the residual entropy (zero temperature entropy) of ice I h. [3] For this (and other) reasons the rules are sometimes mis-attributed and referred to as "Pauling's ice rules" (not to be confused with Pauling's rules for ionic crystals). A nice figure of the resulting structure can be found in ...

  6. Pitch (resin) - Wikipedia

    en.wikipedia.org/wiki/Pitch_(resin)

    [A wood-based pitch] [note 1] is put into an earthen vessel, and it is put over a small fire in the sun, then some hot water percolated through wood-ashes is poured on it, and the pitch is stirred; when it has afterward stood, it is poured out after two hours, then there is as much water again poured in. Having therefore done this thrice every ...

  7. Fluorine compounds - Wikipedia

    en.wikipedia.org/wiki/Fluorine_compounds

    The bond energy is significantly weaker than those of Cl 2 or Br 2 molecules and similar to the easily cleaved oxygen–oxygen bonds of peroxides or nitrogen–nitrogen bonds of hydrazines. [8] The covalent radius of fluorine of about 71 picometers found in F 2 molecules is significantly larger than that in other compounds because of this weak ...

  8. Polyvinyl acetate - Wikipedia

    en.wikipedia.org/wiki/Polyvinyl_acetate

    As wood glue, PVAc is known as "white glue" and the yellow as "carpenter's glue". As paper adhesive during paper packaging conversion. In bookbinding and book arts, due to its flexible strong bond and non- acidic nature (unlike many other polymers).

  9. Fluorine - Wikipedia

    [21] [22] Conversely, bonds to other atoms are very strong because of fluorine's high electronegativity. Unreactive substances like powdered steel, glass fragments, and asbestos fibers react quickly with cold fluorine gas; wood and water spontaneously combust under a fluorine jet. [5] [23]
