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 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 ...

Semiconductor nanocrystals are conducting materials with a size that has been reduced to the nanoscale. This size reduction can greatly enhance the physical, chemical, and optical characteristics, ...

XPS is a very versatile method that has found extensive use in numerous application areas, from aerospace materials to contact lenses. XPS is unique in that it can quantify the chemical and elemental ...

Transmission Raman Spectroscopy is a variation of transmission Raman spectroscopy that is often used to probe the bulk properties of samples that scatter diffusely. It is particularly useful for the ...
