Tammann temperature was pioneered by German astronomer, solid-state chemistry, and physics professor Gustav Tammann in the first half of the 20th century. [1]: 152 He had considered a lattice motion very important for the reactivity of matter and quantified his theory by calculating a ratio of the given material temperatures at solid-liquid phases at absolute temperatures.
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] At Coventry cathedral, Araldite adhesive was used to bond its columns and fins, while at Sydney Opera House, Araldite adhesive was used to bond the rib sections of the shells ...
Specific modulus: Modulus per unit volume (MPa/m^3) Specific strength: Strength per unit density (Nm/kg) Specific weight: Weight per unit volume (N/m^3) Surface roughness: The deviations in the direction of the normal vector of a real surface from its ideal form; Tensile strength: Maximum tensile stress of a material can withstand before ...
White sands test sample, owned by Thermashield, LLC. Starlite is an intumescent material said to be able to withstand and insulate from extreme heat. It was invented by British hairdresser and amateur chemist Maurice Ward (1933–2011) during the 1970s and 1980s, and received significant publicity after coverage of the material aired in 1990 on the BBC science and technology show Tomorrow's ...
The kelvin (the unit name is spelled with a lower-case 'k') is the unit of temperature in the International System of Units ... 1.4 × 10 −3 nm (gamma rays)
Crystal structure of β-glucosidase from Thermotoga neapolitana (PDB: 5IDI).Thermostable protein, active at 80°C and with unfolding temperature of 101°C. [1]In materials science and molecular biology, thermostability is the ability of a substance to resist irreversible change in its chemical or physical structure, often by resisting decomposition or polymerization, at a high relative ...
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.
This is the rating required to protect microfilm, microfiche, and other film-based information storage media. Above 150 °F (65.5 °C) film is distorted by the heat and information is lost. A Class 150-2 Hour vault must keep the temperature below 150 °F. for at least two hours, with temperatures up to 2,000 °F. (1,093.3 °C) outside the vault.
