Foldable Material Can Support Many Times its Weight

Researchers at Drexel University and Dalian University of Technology in China have chemically engineered a new, electrically conductive nanomaterial that is flexible enough to fold, but strong enough to support many times its own weight. They believe it can be used to improve electrical energy storage, water filtration, and radio frequency shielding in technology from portable electronics to coaxial cables.

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.

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.

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.

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.

Solar Material Converts 90 Percent of Captured Light into Heat

A multidisciplinary engineering team at the University of California, San Diego developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity. “We wanted to create a material that absorbs sunlight that doesn’t let any of it escape. We want the black hole of sunlight,” said Sungho Jin, a professor in the department of Mechanical and Aerospace Engineering at UC San Diego Jacobs School of Engineering. Jin, along with professor Zhaowei Liu of the department of Electrical and Computer Engineering, and Mechanical Engineering professor Renkun Chen, developed the Silicon boride-coated nanoshell material. The novel material features a “multiscale” surface created by using particles of many sizes ranging from 10 nanometers to 10 micrometers. The multiscale structures can trap and absorb light which contributes to the material’s high efficiency when operated at higher temperatures.SourceAlso: Read more Materials tech briefs.

2-in-1 Motor Increases Range of Electric Cars

Scientists from Nanyang Technological University (NTU) and German Aerospace Centre (DLR) have invented a 2-in-1 electric motor that increases the range of electric vehicles. The engine integrates the traditional electric motor with the air-conditioning compressor, typically two separate units. This novel, space-saving design allows the use of bigger batteries, which can increase the range of electric vehicles by an additional 15 to 20 percent.
