Around 1950, researchers from the Technion Institute in Haifa (Israel) and from New York University tried to explain this effect scientifically. [6] In fact, there are two phenomena that contribute to this effect: on the one hand, the Bernoulli equation is used to explain it, on the other hand, the adhesion between the liquid and the spout material is also important.
The tendency for a material to form a glass while quenched is called glass forming ability. This ability depends on the composition of the material and can be predicted by the rigidity theory. [12] Below the transition temperature range, the glassy structure does not relax in accordance with the cooling rate used.
Diffuse reflection - Generally, when light strikes the surface of a (non-metallic and non-glassy) solid material, it bounces off in all directions due to multiple reflections by the microscopic irregularities inside the material (e.g., the grain boundaries of a polycrystalline material or the cell or fiber boundaries of an organic material ...
The exact reverse of radiative recombination is light absorption. For the same reason as above, light with a photon energy close to the band gap can penetrate much farther before being absorbed in an indirect band gap material than a direct band gap one (at least insofar as the light absorption is due to exciting electrons across the band gap).
Having a narrow, tail-like appendage or tip, e.g. a drip tip. Contrast acuminate, cuspidate, and mucronate. caudex. pl. caudices. The stem of a plant, especially a woody one; also used to mean a rootstock, or particularly a basal stem structure or storage organ from which new growth arises.
edge distance Drilled holes, and fasteners are commonly required to have a minimum edge distance (min ED). EO, ECO, ECN: engineering order: An order from the engineering department (to be followed by the production department or vendor) overriding/superseding a detail on the drawing, which gets superseded with revised information.
In materials science, material failure is the loss of load carrying capacity of a material unit. This definition introduces to the fact that material failure can be examined in different scales, from microscopic, to macroscopic. In structural problems, where the structural response may be beyond the initiation of nonlinear material behaviour ...
The built up edge effectively changes tool geometry and rake steepness. It also reduces the contact area between the chip and the cutting tool, [1] leading to: A reduction in the power demand of the cutting operation. [1] Slight increase in tool life, since the cutting is partly being done by the built up edge rather than the tool itself. [4]
