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.
Researchers have created a new theoretical framework which could help physicists and device engineers design better optoelectronics, leading to less heat generation and power consumption in electronic devices which source, detect, and control light.
