Granular matter
Extracting micro-structural and rotational information in granular materials such as: sand-piles, coffee beans, planetary rings, powders…
Semi-quantum mechanical explanation
The incoming beam has a polarisation perpendicular to the magnetic field in the precession regions. In the field one can consider the wave…
Gratings
In the figure we show SESANS measurements on a silicon line-grating with a period of 12 mm, a ridge height of 40 mm and a ridge width of 4…
Micro-emulsion (cream cheese)
Systems of practical relevance to the food industry are often hard to investigate non-invasively. This is caused by the fact that most food…
