December 9, 2013 — Researchers are developing a family of generators that provide power for portable electronic devices and sensors by harnessing the triboelectric effect to capture mechanical energy that would otherwise be wasted.
November 15, 2013 — Optimization research provided by Georgia Tech helped improve a computer algorithm used to ensure that electricity generation meets the demand in Brazil. The country relies heavily on hydroelectric facilities for its electricity.
Research Horizons Spring-Summer 2013 — Research surrounding smart grid issues is a major focus of energy and sustainable infrastructure studies at Georgia Tech. The research crosses many disciplines, including electrical and computer engineering, public policy, mechanical engineering and information security.
October 21, 2013 — A new Department of Energy grant will fund research to advance an additive manufacturing technique for fabricating three-dimensional nanoscale structures from a variety of materials. The technique uses high-speed, thermally-energized jets to deliver both precursor materials and inert gas.
October, 17, 2013 – The Carbon-Neutral Energy Solutions (CNES) Laboratory ribbon cutting and dedication ceremony was held on Oct. 17. The lab is the latest addition to the North Avenue Research Area (NARA) complex, on the southwestern edge of campus. The mission of CNES is to bring together a diverse mix of experts to solve some of the big technological problems in clean energy and partner with industry to bring these solutions to the market. So far, solar research at CNES, with numerous projects, patents and industry partnerships, is a shining example of things to come.
September 25, 2013 — For owners of delivery truck fleets who may be trying to decide between electric or diesel vehicles, researchers at the Georgia Institute of Technology are offering some advice: comparisons of the energy consumption, greenhouse gas emissions and total cost of ownership for the medium-duty vehicles.
June 6, 2013 — A new set of long-term climate records based on cave stalagmites collected from tropical Borneo shows that the western tropical Pacific responded very differently than other regions of the globe to abrupt climate change events. The 100,000-year climate record adds to data on past climate events.
April 16, 2013 — Researchers are developing a novel technology that would facilitate close monitoring of bridges, parking decks and other structures for early signs of strain, stress and formation of cracks. Their approach uses wireless sensors that are low cost, require no power, and can be implemented on tough yet flexible polymer substrates.
April 9, 2013 — Controlling the shapes of nanometer-sized catalytic and electrocatalytic particles made from noble metals such as platinum and palladium may be more complicated than previously thought. Using systematic experiments, researchers have investigated how surface diffusion – a process in which atoms move from one site to another on nanoscale surfaces – affects the final shape of the particles.
February 18, 2013 — When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn’t matter that much, according to a report published this week in the journal Proceedings of the National Academy of Sciences. And that’s good news for reducing the uncertainty of climate model predictions.
