"Luftmensch," literally meaning "air person," is the Yiddish way of describing someone who is a bit of a dreamer. Did You Know? The word "infant" comes from the Latin word "infans" which literally means "unable to speak; speechless." ...
Solidification is nearly always anexothermicprocess, meaning heat is released when a liquid changes into a solid. The only known exception to this rule is the solidification of low-temperature helium. Energy (heat) must be added to helium-3 and helium-4 for freezing to take place. Solidificatio...
In their model, the rate of spread is thus controlled by isolating each node during its solidification, meaning that a node cannot trigger solidification in the neighboring node until it is totally solid. According to them, the rate of spread v(T) is also temperature dependent and is given ...
In subject area: Engineering 1,9,10 A precipitation/solidification process is used to transform a polymer solution into two phases (a polymer-rich solid and a polymer-lean liquid phase). From: Handbook of Membrane Reactors: Fundamental Materials Science, Design and Optimisation, 2013 About this ...

We report the results of a phase-field study of degenerate seaweed to tilted dendrite transition and their growth dynamics during directional solidification of a binary alloy. Morphological selection maps in the planes of (G, Vp) and (ε4, Vp) show that

Practically, the sonotrode at this stage would be well below the liquidus temperature of the melt by hundreds of degrees, meaning that the region beneath the sonotrode remains the coldest region of the casting compared to mould walls and grain formation is favored by a high thermal undercooling ...
[17], the physical meaning of the drag parameter is related to material compositions transferred across the interface. While ΔGDF and ΔGD are always larger than zero, ΔGC might be less than zero in the no drag model according to Eq. (10b). This is in conflict with the analysis made...
