Active pharmaceutical ingredients (APIs) are typically produced through crystallization. In this process, an organic molecule can take on multiple crystalline forms. Solid-state characteristics, ...

Raman spectroscopy uses inelastic scattering of protons from molecules that are covalently bound in order to identify functional groups, stresses, strains and crystallinity. It is a tool that is ...

Raman imaging and scanning electron microscopy (SEM) was used to investigate acetaminophen solid dispersions prepared by hot melt extrusion (HME). This experiment confirmed that a high screw speed ...
