In general, the role of materials for X rays can be represented as , where the refractive index decrement determines the phase shift of the X rays passing through the object.
Therefore, X-ray phase contrast imaging is more sensitive than traditional X-ray absorption technique in the fields of medicine and material science, etc.
It includes three gratings, a conventional X-ray tube, precision machinery stepping device, detector, biological samples or soft materials tested and the computer image processing unit.

Modern science has extended the use of curcumin to the pharmaceutical industry as a therapeutically active ingredient.
Compared to the conventional methods, SCF technology provides higher compatibility for thermo-labile materials such as pharmaceutical and foods.
The use as solute or as solvent exploits the compatibility of the SCF with the processed materials to generate homogenous mixtures, followed by expansion through nozzle to initiate particle formation.
