    en.wikipedia.org/wiki/Tris(pentafluorophenyl)borane

    Tris (pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C6F5)3B. It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC3 core is planar. It has been described as the “ideal Lewis acid ” because of its high ...

    en.wikipedia.org/wiki/Board_foot

    An example of planed lumber is softwood "two by four" lumber sold by large lumber retailers, nominally 2 by 4 inches (50 mm × 100 mm). The 2 × 4 is actually only 1 + 1 ⁄ 2 in × 3 + 1 ⁄ 2 in (38 mm × 89 mm), but the dimensions for the lumber when purchased wholesale could still be represented as full 2 × 4 lumber, although the "standard ...

  6. Wood drying - Wikipedia

    en.wikipedia.org/wiki/Wood_drying

    Wood drying. Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood:

  7. Standard electrode potential (data page) - Wikipedia

    en.wikipedia.org/wiki/Standard_electrode...

    The data below tabulates standard electrode potentials (E °), in volts relative to the standard hydrogen electrode (SHE), at: Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa). Variations from these ideal conditions ...

  8. Moody chart - Wikipedia

    en.wikipedia.org/wiki/Moody_chart

    Moody chart. In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor fD, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.
