by Sergio Medeiros, RadTech South America Board Member and Founder and Director of BRCHEMICAL Maybe I’m not a typical Brazilian: I don’t like Carnival. I also don’t much like Açaí, although Açaí goes very well with bananas and other fruits, which remind me of Carmen Miranda, a Portuguese singer. Many people thought she was Brazilian, myself included, until running some quick … [Read more...] about More than Carnival and Açaí: An Update from RadTech South America

IBOA-Free Medical LCA Adhesive for Wearable Technology
By Shuhua Jin, Yiwei Dai, Nicholas Baruffi and Chihmin Cheng, Henkel Corporation The use of medical wearables for self-health monitoring and digital care has risen rapidly in recent years. Most traditional medical light cure acrylate (LCA) adhesives contain isobornyl acrylate (IBOA), which has been reported to cause severe skin-sensitization in patients. To meet the increasing … [Read more...] about IBOA-Free Medical LCA Adhesive for Wearable Technology
Sustainable Raw Materials in Additive Manufacturing
By Corey Long and Clémentine Champagne, Arkema Additive manufacturing generally is considered to be a more environmentally responsible technology by enabling on-demand, local production, with the potential to reduce material waste and minimize the logistic footprint. The key to unlocking its full potential lies in the use of more sustainable raw materials. These innovations … [Read more...] about Sustainable Raw Materials in Additive Manufacturing
Photo-Rheology and FTIR Cure Analysis of Photopolymer Resins for Additive Manufacturing
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
