Squalane is the organic compound with the formula ((CH 3) 2 CH(CH 2) 3 CH(CH 3)(CH 2) 3 (CH 2) 3 CH(CH 3)(CH 2) 2) 2. A colorless hydrocarbon, it is the hydrogenated derivative of squalene, although commercial samples are derived from nature. [3] In contrast to squalene, due to the complete saturation of squalane, it is not subject to auto ...
Cans imported from the US often have odd sizes such as 3.8 L (1 US gallon), 1.9 L (1/2 US gallon), and 946 ml (2 US pints / 1 quart). In the UK and Australia, cans are usually measured by net weight. A standard size tin can holds roughly 400 g; though the weight can vary between 385 g and 425 g depending on the density of the contents.
TTT diagram of isothermal transformations of a hypoeutectoid carbon steel; showing the main components obtained when cooling the steel and its relation with the Fe-C phase diagram of carbon steels. Austenite is slightly undercooled when quenched below Eutectoid temperature. When given more time, stable microconstituents can form: ferrite and ...
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.
Melt is the working material in the steelmaking process, in making glass, and when forming thermoplastics. In thermoplastics, melt is the plastic in its forming temperature, which can vary depending on how it is being used. [1] For steelmaking, it refers to steel in liquid form. [2]
The main problem with this theory is that the stored energy due to dislocations is very low (0.1–1 J m −3) while the energy of a grain boundary is quite high (~0.5 J m −3). Calculations based on these values found that the observed nucleation rate was greater than the calculated one by some impossibly large factor (~10 50 ).
The Simon–Glatzel equation [1] is an empirical correlation describing the pressure dependence of the melting temperature of a solid.The pressure dependence of the melting temperature is small for small pressure changes because the volume change during fusion or melting is rather small.

A fuel container is a container such as a steel can, bottle, drum, etc. for transporting, storing, and dispensing various fuels.
