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.

Cubic boron arsenide as a novel material for cooling of electronic devices

A team of theoretical physicists at the U.S. Naval Research Laboratory (NRL) and Boston College has identified cubic boron arsenide as a material with an extraordinarily high thermal conductivity and the potential to transfer heat more effectively from electronic devices than diamond, the best-known thermal conductor to date.

Speed limit set for ultrafast electrical switch

Researchers from the U.S. Department of Energy's SLAC National Accelerator Laboratory have clocked the fastest-possible electrical switching in magnetite, a naturally magnetic mineral. Their results could drive innovations in the tiny transistors that control the flow of electricity across silicon chips, enabling faster, more powerful computing devices.

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.
