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…

Kadine Mohomed – Characterization of Amorphous Pharmaceuticals by DSC Analysis

Kadine Mohomed – Characterization of Amorphous Pharmaceuticals by DSC Analysis The glass transition temperature of an amorphous pharmaceutical solid is a critical physical property that can greatly influence the material’s chemical stability, physical stability, and viscoelastic properties. Thankfully with specific analytical tests made possible through the use of Differential Scanning Calorimetry, this and other thermal…

Morphology Of Complex Nanoparticle Mixtures

Morphology Of Complex Nanoparticle Mixtures The performance of new materials and devices depend heavily on morphological considerations: degree of crystallinity, conformation of amorphous species, and relative organization of one species with respect to another, characteristics which can be determined by thermal analysis. These considerations are important for functional materials such as photovoltaics and MEMS devices,…

An Introduction to Lifetime Testing by Thermogravimetry

An Introduction to Lifetime Testing by Thermogravimetry Lifetime testing by thermogravimetry (TGA) is a well-established, powerful technique for predicting the long-term aging characteristics of a material in a short experimental time. Multiple techniques and models are presented and compared for lifetime testing, including Modulated TGA™, and a survey of the current ASTM methods and the…
