Garnet Ceramics Could Be the Key to High-Energy Lithium Batteries

Scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered exceptional properties in a garnet material that could enable development of higher-energy battery designs. The ORNL-led team used scanning transmission electron microscopy to take an atomic-level look at a cubic garnet material called LLZO. The researchers found the material to be highly stable in a range of aqueous environments, making the compound a promising component in new battery configurations.

New Compounds Developed to Manufacture Tunable OLED Devices

Researchers have developed new organic compounds characterized by higher modularity, stability, and efficiency that could be applicable for use in electronics or lighting. A proof-of-concept project has begun to verify that the compounds have the photoluminescence and electrochemical properties required for the manufacture of tunable organic LEDs (OLEDs) that can emit in the blue portion of the visible spectrum, thus applying lower voltages and achieving greater efficiency and longer life.

NASA's Hot 100 Technologies: Power Generation & Storage

Model-Based Prognostics For Batteries Effective Battery Health Monitoring (BHM) technologies are needed to ensure that battery operation is optimal and, if not, that it stays within design limits. BHM technologies protect the asset’s batteries from degradation due to non-optimal usage, and ensure viable levels of system availability, reliability, and sustainability in the presence of degraded batteries.

Technique Generates Electricity from Mechanical Vibrations

Research scientists at VTT Technical Research Centre of Finland have demonstrated a new technique for generating electrical energy. The method can be used in harvesting energy from mechanical vibrations of the environment and converting it into electricity. Energy harvesters are needed in wireless self-powered sensors and medical implants, where they could ultimately replace batteries. The technology could be introduced on an industrial scale within three to six years.

2014 Create the Future Design: Sustainable Technologies Category Winner

ecovent Systems — Make Every Room the Right Temperature Dipul Patel, Yoel Kelman, Nick Lancaster, Shawn Rose, and Brian Bowen ecovent Systems Boston, MA“Sustainability has always been a driving force for ecovent, and winning this award is a great testament to that fact. We are passionate about helping people live more comfortably while saving energy. To us, that’s the definition of ‘creating the future.’ Saving energy shouldn’t be a chore, it should be fun – and even better than the status quo. That’s the product we’ve built and we’re glad that the voters were excited by it.”Most homes have only one thermostat, so they operate like a house with only one light switch — everything is either on or off. That leaves some rooms boiling hot while others are freezing cold. It’s uncomfortable, and it’s inefficient.
