Hollow-Fiber MOF Membranes Could Cut Separation Costs, Energy Use

July 3, 2014 -- Researchers have developed a microfluidic technique for fabricating a new class of metal-organic framework (MOF) membranes inside hollow polymer fibers that are just a few hundred microns in diameter. The new fabrication process, believed to be the first to grow MOF membranes inside hollow fibers, could potentially change the way large-scale energy-intensive chemical separations are done.

Engineered Bacteria Produce Biofuel Alternative for High-Energy Rocket Fuel

March 26, 2014 -- Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications.

OneBusAway App Now Tracks MARTA Trains in Real Time

March 5, 2014 - The mobile app OneBusAway, which tracks public transportation in real time, now includes arrival times for MARTA trains in addition to the MARTA buses and Georgia Tech shuttles already featured in the app.

Solar-Induced Hybrid Fuel Cell Produces Electricity Directly from Biomass

February 18, 2014 -- Researchers have developed a new type of low-temperature fuel cell that directly converts biomass to electricity with assistance from a catalyst activated by solar or thermal energy. The hybrid fuel cell can use a wide variety of biomass sources, including starch, cellulose, lignin – and even switchgrass, powdered wood, algae and waste from poultry processing.

Optimizing Energy: $2.9 Million Award Will Help Reduce Fuel Use in Forward Operating Bases

January 16, 2014 -- Georgia Tech researchers have begun a project to develop information that military resource planners can use to optimize energy consumption depending on mission needs and local conditions.
