Morphological Stability of a Planar Rotating Interface, situation can occur for example in the presence of an axial magnetic field. Further, we saw in Chap. 6 how the response of the interface to oscillations of zero wave number, (i.e. plane wave oscillations) gives rise to striations.

Accountability, Silences and Journalism,-melt interface as a thermodynamic phase boundary whose shape represents the solution of the problem and not a boundary condition. Such problems are known as Stefan problems (see for example Ockendon and Tayler ). First, though, we determine the temperature field in the cooling crystal.

Space, Geography and Journalism,ifically it was found that differing oxygen contents could be obtained depending on the sense of the crucible rotation, always with the seed rotating counter to the crucible . Eventually it was discovered that this was due to the rotating magnetic field generated by the three-phase heater elements.

What Constitutes Whistleblowing?,n as RF induction heating in the figure but various other forms are also in common use) to heat the crucible and charge to above the melting point of the latter. A pull rod with a chuck containing a seed crystal at its lower end is positioned axially above the crucible. This seed crystal is dipped i

What Constitutes Whistleblowing?,ke bismuth which melts at only 271 °C up to refractory oxides melting at temperatures approaching 2500 °C necessitates a diverse technology. There is no such thing as the universal crystal pulling machine. However, research pullers are usually modular in construction to permit fitment of d
