The cooling produced in the Joule–Thomson expansion makes it a valuable tool in refrigeration. [8] [20] The effect is applied in the Linde technique as a standard process in the petrochemical industry, where the cooling effect is used to liquefy gases, and in many cryogenic applications (e.g. for the production of liquid oxygen, nitrogen, and ...
Morton Deutsch (February 4, 1920 – March 13, 2017) was an American social psychologist, psychoanalyst, and researcher in conflict resolution. Deutsch was one of the founding fathers of the field of conflict resolution. A Review of General Psychology survey, published in 2002, ranked Deutsch as the 63rd most cited psychologist of the 20th ...
The internal energy of an ideal gas depends only on its temperature, and not on the volume of its containing box, so it is not an energy effect that tends to increase the volume of the box as gas pressure does. This implies that the pressure of an ideal gas has an entropic origin. [5] What is the origin of such an entropic force?
The figure shows one such ideal expansion fan. A supersonic expansion fan, technically known as Prandtl–Meyer expansion fan, a two-dimensional simple wave, is a centered expansion process that occurs when a supersonic flow turns around a convex corner. The fan consists of an infinite number of Mach waves, diverging from a sharp corner. When a ...
Die swell is an instance where a polymer stream is compressed by entrance into a die, and is followed by a partial recovery or "swell" back to the former shape and volume of the polymer after exiting the die, hence the term die swell. The Barus effect is named after his discoverer Carl Barus, who published about it in 1893. [1]
[4] [5] For example, if a stiff conformal coating or other polymeric encapsulation is allowed to flow under a QFN, its expansion and contraction during thermal cycling can add tensile stress to the solder joints and expedite fatigue failures. [6] DIC techniques will also allow the detection of glass transition temperature (T g). At a glass ...

Philipp Lenard.Deutsche Physik, 2. Band – Akustik und Wärmelehre. München, 1936–1937. Deutsche Physik (German: [ˈdɔʏtʃə fyˈziːk], lit. "German Physics") or Aryan Physics (German: Arische Physik) was a nationalist movement in the German physics community in the early 1930s which had the support of many eminent physicists in Germany.
