Chemist monitors nanotechnology's environmental impact

Interest in 'green' innovation means not just thinking big but also very, very, very small. At least that's the way Omowunmi Sadik, director of Binghamton University's Center for Advanced Sensors and Environmental Systems, sees it. She is working to develop sensors that would detect and identify engineered nanoparticles.

The invisibility cloak: one dimension closer to reality

EU-funded researchers have created the first three-dimensional (3D) invisibility cloak and used it to successfully hide a small bump on a gold surface. The findings represent a major advance in the field of transformation optics, which uses a special type of materials called 'metamaterials' that can guide and control light in new ways.
