| Zinc oxide materials tapped for tiny energy harvesting devices Posted: 13 Jan 2015 09:09 AM PST Today, we're surrounded by a variety of electronic devices that are moving increasingly closer to us -- we can attach and wear them, or even implant electronics inside our bodies. Many types of smart devices are readily available and convenient to use. The goal now is to make wearable electronics that are flexible, sustainable and powered by ambient renewable energy.  |
| Posted: 13 Jan 2015 08:15 AM PST Today's lithium-ion batteries are good, but not good enough if our future energy system is to rely on electrical power. Chemists and materials scientists have now developed a type of glass that can be used as an electrode material in lithium-ion batteries -- likely making a vast improvement in these batteries' capacity and energy density.  |
