Hi, I spent some time during my PhD with the task of indexing TEM diffraction patterns, usually made with selected area diffraction. All available software I found online was either too complicated or too expensive (or both). So I decided to make my own: https://www.odpin.com It's 100%...

I spend a lot of my time simulating circuits whose salient feature is their tendency to surge. I like all surges, but especially those which have any potential to be managed... http://is.gd/constcurr The non-manageable ones tend to blow up very suddenly... http://is.gd/kaboomopamp My favorite...

I was wondering if someone could offer an explanation as to why TEMs and SEMs have practical resolutions several orders of magnitude less than what is predicted by the Rayleigh Criterion. This of course comes from my own calculations of the Rayleigh Criterion assuming an electron is accelerated...

Every physics books show that wave prograpation in coxial cable is TEM wave, like in the picture. But we know that J=σ E from ohms law, which says current in same direction with E field, which is not the case here. What do you think the reason is ?

Hey! I have a very unusual question. It is about using ImageJ to analyze diffraction patterns from TEM. 1. Homework Statement To calculate lattice parameter I need Miller Indices from planes I can recognize in the picture, wavelength of electrons and camera length. In our instructions for...

I'm looking for a quick and well synthetized reference to the TEM technique. I'm writing a monography, we used TEM on a sample (just sended it to the lab, I dind't do the work). I don't have any reference, and I wanted to give a kind of introduction in the monography to TEM. I don't want a whole...

What information do you get from TEM images and how do yo obtain it? I am analyzing hydroxyapatite (ceramic).
