DSC Characterization of Crystalline Structure in Foods and Pharmaceuticals

DSC Characterization of Crystalline Structure in Foods and Pharmaceuticals Differential Scanning Calorimetry (DSC) is an analytical technique frequently used to detect and quantify crystalline content of pharmaceuticals, foods, polymers, and many other materials. Appearing as an endothermic peak during heating in a DSC experiment, the temperature and area of the peak can be used to…

Designing New Materials for Additive Manufacturing: Vat Photopolymerization

Designing New Materials for Additive Manufacturing: Vat Photopolymerization Overview 3D printing, or additive manufacturing (AM), provides opportunities to create previously unattainable geometric objects through layer-by-layer fabrication. Novel macromolecular structures and synthetic methods coupled with unique printing methods lead to 3D part generation with micron-scale resolution and tunable to emerging technologies. By tuning polymer structure, printing…
