### 2 Does corrosion of metals depend on electron degeneracy pressure?

Corrosion is about losing electrons for the corroded metal and gaining electrons for the oxidising substance. Is it correct to assume that what controls this process is the electron degeneracy ...

### 13 Why the electrons below the Fermi level do not conduct electricity?

Physically, why is it that the electrons need to excited above the Fermi level to conduct electricity? In other words, why is the current zero when the electrons lie below the Fermi level? Does Pauli ...

### 1 Equation of state for liquid metals (CFD Application)

I am currently looking for the Equation of state used for metals (fluid state) for CFD Application on metallurgy. Do you know a book where I can find them?

### raman tensor of graphène and its polarisability

I want ask about the raman tensor of graphene all that I know, the raman spectrum of graphene has 2 main peak G and 2D. but what about its tensor raman. I know that the metals materials don't have ...

### Is there a way to make infrared pass through metals?

I am curious to know a way that will make infrared pass through metals. Metals are good reflectors of infrared,can we manipulate the wave in order to make them pass through metals?.

### 2 How do liquid metals work?

1 answers, 36 views solid-state-physics metals matter
So in solid metals they atoms give off electrons, which are delocalised and hold together all the metal atoms. But that's not the case in liquid metals, right? What holds together the individual atoms ...

### Does electric field polarity matter for Taylor cone formation?

1 answers, 253 views electric-fields metals
For example in liquid metal ion source (LMIS), the positive electrode is wetted by gallium, which forms a Taylor cone towards the negative electrode and emits Ga+ ions. Would a Taylor cone still form ...

### Why are metals opaque? [closed]

Why are metals opaque? Is it due to the free electrons in a metal or a material's intrinsic properties?

### Would a metamaterial change its properties if one used different isotopes of an atom in its construction?

2 answers, 27 views quantum-spin metals
Given one had a metamaterial of a given type, containing some limited types of elements... if one were to use just one isotope of a given element (assuming it had more than one) in the construction ...

### Tongue and frozen metal [duplicate]

1 answers, 43 views thermodynamics biophysics metals ice
I understand that when you put your tongue on frozen metal, your tongue sticks to the metal but how does having a layer of ice covering the metal prevent your tongue from sticking?

### Any metal or chemical or any thing which repels Iron

I on a project, i required a metal/chemically treated metal/Chemical/anything which repels iron and steel like two same side magents do. I searched in the internet and didn't found anything which ...

### 3 How long does it take a warm object to cool in air?

This is a work-related question. A warm steel torus of a given diameter & thickness is left in a room held at a controlled temperature, how long does it take to reach equilibrium? Assume the air ...
