While drying the paper is in direct contact with the cylinder so if the paint had a colour the paper would probably be coloured as well. I don't think calibrating the emissivity would work well either. Because the surface is not uniform. When trying to calibrate the emissivity I obtained...

The surface I'm supposed to measure is a drying cylinder in a paper machine. I'm supposed to measure the temperature while the machine is running. So in order not to colour the paper the paint needs to be transparent in the visible. It is my master project I'm working on so if anybody have an...

I'm having problems measuring the temperature of a steel surface with varying emissivity with a pyrometer. So I thought one way to overcome the varying emissivity is to paint the surface with a paint that has a high uniform emissivity in the IR region. The paint should: Have high...

Thank you for the help! I will have a look at the PRL by Dan Tsui.

I was about to do a simulation on www.nanohub.org on a MOSFET when the simulation program asked me for the valley degeneracy of the 2DEG. I've tried to look this up but i can't find it anywhere. Does somebody know a website where I can find the valley degeneracy for a 2DEG for Si, GaAs, InAs...

Homework Statement The task is to show that the eigenvalues of overlap matrix \tilde S are positive. Homework Equations The overlap matrix is defined as (\tilde S)_{nm} = \langle \xi_n \vert \xi_m \rangle , with \xi_k being the base vectors of the wavefunction...
