Scientists have demonstrated the potential of silicon nanoparticles for effective non-linear light manipulation. Their work lays the foundation for the development of novel optical devices with a wide range of functionalities.
The energy-storage goal of a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use has been achieved by a team of materials scientists.
Non-toxic, edible batteries could one day power ingestible devices for diagnosing and treating disease. One team reports new progress toward that goal with their batteries made with melanin pigments, naturally found in the skin, hair and eyes.
Researchers have developed an anode material for lithium-ion rechargeable batteries by forming nanoparticles made of silicon-metal composites on metal substrates. The resulting anode material had high capacity and a long cycle life.
