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.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
