  2. Thermal conductivity and resistivity - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductivity_and...

    Temperature dependence of the mean free path has an exponential form /. The presence of the reciprocal lattice wave vector implies a net phonon backscattering and a resistance to phonon and thermal transport resulting finite λ L, [50] as it means that momentum is not conserved. Only momentum non-conserving processes can cause thermal resistance.

  3. Araldite - Wikipedia

    en.wikipedia.org/wiki/Araldite

    Araldite adhesive is used to join together the two sections of carbon composite which make up the monocoque of the Lamborghini Aventador. The use of Araldite adhesive in architecture to bond thin joints of pre-cast concrete units was pioneered by Ove Arup in Coventry cathedral and the Sydney Opera House. [4]

  4. Thermal conductance and resistance - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductance_and...

    The SI unit of absolute thermal resistance is kelvins per watt (K/W) or the equivalent degrees Celsius per watt (°C/W) – the two are the same since the intervals are equal: ΔT = 1 K = 1 °C. The thermal resistance of materials is of great interest to electronic engineers because most electrical components generate heat and need to be cooled.

  5. Tog (unit) - Wikipedia

    en.wikipedia.org/wiki/Tog_(unit)

    So that practical clothing may be described conveniently by a range of small integers, the unit of thermal resistance, to be called the “tog”, is the resistance that will maintain a temperature difference of 0.1°C. with a flux of 1 watt per square metre, or in more practical terms, 10°C. with a flux of 1 watt per square decimetre.

  6. 3ω-method - Wikipedia

    en.wikipedia.org/wiki/3ω-method

    The 3ω-method (3 omega method) or 3ω-technique, is a measurement method for determining the thermal conductivities of bulk material (i.e. solid or liquid) and thin layers. The process involves a metal heater applied to the sample that is heated periodically. The temperature oscillations thus produced are then measured.

  8. Wood glue - Wikipedia

    en.wikipedia.org/wiki/Wood_glue

    Hide glue is measured on the basis of its gel strength, a measure of how many grams of force it requires to depress a 1 ⁄ 2 in (13 mm) plunger 4 mm (0.16 in) into a 12.5% protein solution of the glue at 10 °C (50 °F). Glue is manufactured in standard grades from 32–512 grams (1.1–18.1 oz). 192-gram (6.8 oz) strength is the most commonly ...
