    Piezoelectrics

    Material can turn sunlight, heat and movement Into electricity -- all at once

    Extracting energy from multiple sources could help power wearable technology.

    A perovskite solid-solution that exhibits tunable bandgaps in the visible light energy range is showing promising material for light absorption and conversion applications,(solar energy harvesting and light sensing).

    Such a common ABO3–type perovskite structure, most widely used for ferroelectrics and piezoelectrics, enables the same solid-solution material to be used for the simultaneous harvesting or sensing of solar, kinetic, and thermal energies.

    These results are considered to be a significant improvement compared to those of other compositions which could be used for the same applications. The results pave the way for the development of hybrid energy harvesters/sensors, which can convert multiple energy sources into electrical energy simultaneously in the same material.

    Portland to participate in Whitehouse's Smart Cities Initiative

    80 million investment to build smarter cities. There are some endeavors that are simply too much for any one city to take on by itself.

    NIST’s Global City Teams Challenge is establishing multi-team super-clusters to take on grand challenges too big for any single city team to tackle. Examples include multi-city resilience to large-scale natural disasters, intelligent transportation systems that work in any city, and regional air quality improvements through coordinated local action. This initiative brings together groups of communities formed around lead cities—Portland, Oregon; Atlanta, Georgia; Newport News, Virginia; Columbus, Ohio; Bellevue, Washington; Kansas City, Kansas; and Kansas City, Missouri—to work with NIST and its collaborators, including DOT, DHS Science and Technology Directorate, NSF, the Environmental Protection Agency, the National Telecommunications and Information Administration, the International Trade Administration, the Economic Development Administration, IBM, AT&T, CH2M, Verizon, Qualcomm Intelligent Solutions, Intel, US Ignite, and Urban-X, to develop ‘blueprints’ for shared solutions that will be collaboratively implemented in multiple cities and communities.

    NIST is announcing $350,000 in four new grants enabling 11 cities and communities to work together on innovative smart city solutions. The Replicable Smart City Technologies grants to teams of communities led by Newport News, Virginia; Bellevue, Washington; Montgomery County, Maryland; and Portland, Oregon focus on the development and deployment of inter-operable technologies to address important public concerns regarding air pollution, flood prediction, rapid emergency response, and improved citizen services through inter-operable smart city solutions that can be implemented by communities of all types and sizes.

    Quant-06

    It's like the DeLorean and the Tesla had a baby!

    Salt water-powered automobiles are a step closer to reality -- recently approved* in Europe.

    "The QUANT e-Sportlimousine features the revolutionary nanoFLOWCELL® energy storage technology – a further development of tried and tested redox flow-cell systems. The nanoFLOWCELL® sets itself apart from other systems in its ability to store and release electrical energy at very high energy densities. The very compact and powerful nanoFLOWCELL® battery system in the QUANT e-Sportlimousine prototype can power it for a driving range of up to 600 kilometres."
