By Nicholas Gripp, Applied Molecules LLC This study undertakes a comprehensive examination of the photopolymerization kinetics of materials commonly used in additive manufacturing, focusing on the discernment of gel point vs. cure point. Leveraging the sensitivity of photo-rheology, 1 the onset of gelation is precisely identified, marking the transition from viscous to elastic … [Read more...] about Photo-Rheology and FTIR Cure Analysis of Photopolymer Resins for Additive Manufacturing
Photopolymerizations for Creating Engineered Microenvironments: From 3D Culture Models to Biomanufacturing Facilitated by Interdisciplinary Collaborations
By April M. Kloxin, Ph.D., Chemical and Biomolecular Engineering and Materials Science and Engineering, University of Delaware Photochemistry increasingly is used as a tool in both academic and industrial applications, largely owing to its scalability and precision in controlling when and where reactions happen under mild conditions through the application of light. 1-3 … [Read more...] about Photopolymerizations for Creating Engineered Microenvironments: From 3D Culture Models to Biomanufacturing Facilitated by Interdisciplinary Collaborations

If the Shoe Fits… Thank UV, Not Cinderella
The proverb “if the shoe fits” first appeared as “if the cap fits” in a poem by Daniel Defoe in 1705. The expression evolved by the late 18th century and eventually became associated with the glass slipper in the fairy tale, “Cinderella.” Cinderella is a fairy tale with a happy, predictable ending. This column is a real-world tale and is best described as a work-in-progress … [Read more...] about If the Shoe Fits… Thank UV, Not Cinderella
The Cost and Value of Electron Beam
The capital cost of an electron beam often is cited as a disqualification for consideration. Just this past May at the RadTech event, a presenter excluded EB in a comparison study, before seeking any performance results, because it is an expensive technology – implying that even if it did meet all the tested criteria, it wasn’t worth presenting to customers as a solution … [Read more...] about The Cost and Value of Electron Beam
