Researchers have achieved optical waveguiding of near-infrared light through features embedded in self-assembled, three-dimensional photonic crystals. Applications for the optically active crystals include low-loss waveguides, low-threshold lasers and on-chip optical circuitry.
Developing smart, multifunctional materials that can be used in protective clothing, medical applications and buildings is the goal of the EU-funded INTELTEX ('Intelligent multi-reactive textiles integrating nano-filler based CPC-fibres') project.
One currently popular response to rapid technological evolution is to call for 'the democratization of technology.' Among other things, this approach calls for increased awareness and sensitivity of technologists to the social implications of their work, and greater efforts to include society in decisions regarding the particular structure and deployment of various technologies.
Nanotechnology would soon have a pervasive effect on automotive products and manufacturing processes in the automobile industry, said Hyderabad-based International Advanced Research for New Materials Research Centre director G Sundara Rajan.
The National Science Foundation's Center for Nanotechnology in Society (CNS), housed at UC Santa Barbara, recently hosted a major conference on health and safety in laboratories and industrial workplaces employing nanotechnology.
