Amorphous polymer dynamics and free volume element size distributions from ultrafast IR spectroscopy
A method for measuring the size and size probability distribution of free volume regions in polymeric materials using ultrafast infrared (IR) polarization-selective pump–probe experiments is presented ...

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 ...
In this interview, Dr. Joshua Lea explores the role of the integration of Raman spectroscopy with SEM technology for advanced materials analysis. Can you introduce yourself and the topic you will be ...
