Solution-grown nanowires make the best lasers
Take a material that is a focus of interest in the quest for advanced solar cells. Discover a 'freshman chemistry level' technique for growing that material into high-efficiency, ultra-small lasers.
Team develops elastic-composite nanogenerator (w/video)
Scientists have demonstrated a facile methodology to obtain a high-performance and hyper-stretchable elastic-composite generator using very long silver nanowire-based stretchable electrodes.
Creating bare, two-metal particles provides insights into potential substitutes for costly platinum in fuel cell catalysts
Platinum's scarcity hinders widespread use of fuel cells, which provide power efficiently and without pollutants. Replacing some or all of this rare and expensive metal with common metals in a reactive, highly tunable nanoparticle form may expand fuel cell use.
New ways to see light and store information
Researchers have developed a method that significantly prolongs the lives of charges in organic electronic devices.
