What is the undercooling temperature for pure iron?

I am working on solidification of metals. Iron/steel has been intensively studied. Generally all the steels contain impurities and intermetallics or precipitates. Therefore, they can nucleate...

Any suggestions about doping concentration?

Dear everone, I have a simple question about the definition of doping concentrations. For example, one presents his/her doping formula for a complex crystal as: ABmCn:X. Then the author states...

Publications: Generallized/popular or specialized one?

I have been puzzled by a question about the choice of a journal for research results. Nowadays, many researchers choose a popular journal (with a high impact factor) rather than a specific...

Can someone help me and tell me about the difference between a surface of amorphous silica and a stable surface of quartz (crystalline silica) ?

Topologically both a-Silica and c-Silica are composed of SiO4 tetragonal coordination and O-Si2 bridging bonding. Should there be significant differences for the Si and atoms on surfaces ?

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
