Teaching phylogenetic analysis with bolts?

I found some time ago a paper dealing with teaching phylogenetics. The objects of the phylogenetic analysis were various type of bolts. I cannot find again that reference. Anyone can give me a...

How can I determine the Mott Schottky effect for a semiconducting film (200 nm) deposited on a highly doped (0.05 ohms) n type Si substrate?

I would like to know if it is possible to determine the sign of carriers and concentration (from 1/C2 vs Bias dependency) for such system. It is crucial to deposit the film on a metallic...

For an asymmetric scan at a constant incident angle of 3 degree (Detector Scan), are there corrections needed for a 2 theta angle?

For a thin film on a silicon substrate I performed a scan at a fixed incident angle of 3 degree (I couldn't go lower from technical reasons). I got a nice scan but my question is if I have to...

Absorptance of a transparent thin film on a thick glass?

For normal incidence of light can we really neglect the reflected light (in a spectrometer using an integrating sphere).

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...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

What is the state of the drug inside solid lipid nanoparticles (SLNs)?

I am a little confuse with the mechanism of solid lipid nanoparticles (SLNs). The main point of encapsulating drugs into SLNs is because some drugs have low solubility in water. Therefore, SLNs...

Should we reduce the standard unit of length to 0.31951540592 meter ?

The reasoning behind this question is to align the ratios of the proton potential in energy per charge to the speed of light in distance per time. As these two dimensions appear to be related,...

Is is possible to pole with corona poling pellets of the sample material instead of thin films?

As it is highly probable that pellets will have a higher degree of air gaps and voids than thin films, is it possible to pole the samples with corona poling nevertheless? Or is there the...
