$X-ray Diffraction of Biological Samples$ 01:10

X-ray Diffraction of Biological Samples

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Background:

Industrial heterogeneous catalysis and gaseous corrosion studies require understanding surface behavior under high pressure.
Existing techniques often lack the capability to perform surface-sensitive analyses at pressures relevant to industrial processes.

Purpose of the Study:

To demonstrate a proof of concept for a new high-pressure reaction cell design.
To enable surface-sensitive X-ray measurements under industrially relevant conditions.

Main Methods:

Design and implementation of a high-pressure heterogeneous catalysis reaction cell.
