Jennifer Lewis made a discovery that could effect the future of electrical ceramics. The University of Illinois professor is working with NASA's office of Biological and Physical Research and studying how materials form when gravity is not present. By subtracting gravity from the process, she sees what happens when a given material is produced. Lewis co-authored a paper describing a process called "nanoparticle haloing" that stabilizes particles in fluids and prevents them from coagulating into a disordered structure. She indicates that by varying the composition of colloidal fluids and gels, researchers produce systems whose properties vary dramatically. "This designer capability will assist us in developing improved materials for photonics that control the flow of light," she says.

Content for the colloids website includes copies of Lewis's research papers and links to professional societies.
As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers.
Stratasys will be exhibiting two groundbreaking large-scale additive manufacturing technologies, as well as other new products, next month at the International Manufacturing Technology Show (IMTS) in Chicago.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
