## Videos

This page contains the list of (Youtube) videos I have made over time explaining SAXS and some of its workings. They are mostly sorted in order of appearance (newest on top)

Some new 2D fitting work I am developing at the moment (more information):

A presentation discussing a small-angle scattering technicality, what is the visibility of particular sizes in polydisperse samples? (more information):

A promotional video for a NIMS workshop:

A demonstration of small-angle scattering from a hair. This is a demonstration in which beams of laserlight (two lasers with different wavelengths are used to demonstrate the effect of different wavelengths as well) is shone upon two human hair samples. A small-angle scaattering pattern is seen on a whiteboard and analysed to determine the diameter of the hairs.

…and the calculation of their diameters from the small-angle scattering pattern

A demonstration of what we would see when we scatter from some samples, using a live Fourier Transform image of a laptop camera:

An explanation of what I did from 2009 to 2011 with a concise SAXS explanation and some elaboration on analysis methods:

A short explanation of small-angle scattering:

Hey!great videos, thanks!but i think at the 3rd one, where you calculate the diameters, towards the end of the video (around 4:17) you say q is wavelength independent, do you mean r is independent since you calculate q taking into account wavelength?

Good afternoon Brian,

I wish to incorporate your video, entitled: “Small-angle X-ray Scattering (no voice-over, no closed caption)” in my x-ray safety training for my students. May I have your permission to do so? I will acknowledge your authorship of this clip in my presentations.

Thanks for kind consideration.

Auggie

hi nice vids,

I wish to use your hi-res video in one of my presentations,
thank you very much.
