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)

A user interface for McSAS (more information):

A new Live Fourier Transform demonstration (more information):

Introducing dr. Julian Rosalie (more information):

Introducing dr. Shivani Sharma (more information):

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

A presentation detailing my current work (more information):

A presentation with advice for scientific presenters (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.

    Your videos seem to imply that scattered intensity can pass through the beam stop. This doesn’t seem to make any sense.

    Hi Brian,
    I’d like to use your video “Small-angle X-ray Scattering (no voice-over, no closed caption)” in the ppt presentation of my diploma thesis which is based on usage of SAXS in regards of conformation of biopolyelectrolytes. May I have your permission to do so? I will acknowledge your authorship of this clip in my ppt.

    Thanks

    Hi Brian,

    Whats difference between SAXS and XRD .

    Hi Brian,
    That was very good information,thanks for sharing.
    I am currently working on XRD . Can we perform SAXS analysis of a tablet, a whole tablet i.e without crushing?
    Can this technique be used for quatification analysis?

    Regards,
    Raksha

    Hi Brian!
    I would like to ask you how does the SAXS help to identify the pore shape (the network system) of the porous materials ?
    Thanks in advance.

    Hello,
    Yes it’s about ordered mesoporous materials (with block copolymer as a surfactant), where SAXS ‘s been usually used to identify the structure or to confirm images got by the SEM (Scanning Electron Microscope) or TEM (Transmission Electron Microscope).
    Thanks a lot.

    Hi Brian!
    First of all thank you for your nice videos.
    Can you do any video for SANS and SAXS date analysis?

    Dear Brain,

    I’d like to ask your permission to use your video “Small-angle X-ray Scattering (no voice-over, no closed caption)” in my presentation about SAXS for student in Thailand. I’ll acknowledge your authorship in my ppt presentation.

    Thank you very much
