Tetrapod quantum dots light the way to stronger polymers

Fluorescent tetrapod nanocrystals could light the way to the future design of stronger polymer nanocomposites. Researchers have developed an advanced opto-mechanical sensing technique based on tetrapod quantum dots that allows precise measurement of the tensile strength of polymer fibers with minimal impact on the fiber's mechanical properties.

A new way to create 'gradients' for understanding molecular interactions

Scientists use tools called gradients to understand how molecules interact in biological systems. Researchers from North Carolina State University have developed a new technique for creating biomolecular gradients that is both simpler than existing techniques and that creates additional surface characteristics that allow scientists to monitor other aspects of molecular behavior.

Using nanoparticles to remove pollutants and contaminants from wastewater

The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and its European partners have developed several effective processes for eliminating persistent pollutants from wastewater. Some of these processes generate reactive species which can be used to purify even highly polluted landfill leachate while another can also remove selected pollutants which are present in very small quantities with polymer adsorber particles.
