September 7, 2014 -- A new class of synthetic platelet-like particles could augment natural blood clotting for the emergency treatment of traumatic injuries – and potentially offer doctors a new option for curbing surgical bleeding and addressing certain blood clotting disorders without the need for transfusions of natural platelets.
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.
April 29, 2014 -- Research laboratories at Rice University and Georgia Tech have tested the fracture toughness of graphene for the first time by making and measuring "pre-cracks" under stress.
Research Horizons Winter-Spring 2014 -- Materials research is a major priority at Georgia Tech that involves some 200 faculty members. Major research areas include materials for electronics, infrastructure, energy, environment, transportation, biotechnology, aerospace and defense.
April 6, 2014 -- A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them.
March 30, 2014 -- By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer -- operating at temperatures of up to 200 degrees Celsius.
February 18, 2014 -- A research collaboration has demonstrated the world's fastest silicon-based device to date. The investigators operated a silicon-germanium (SiGe) transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicon-germanium chips by about 200 GHz.
February 16, 2014 -- One factor that makes glioblastoma cancers so difficult to treat is that malignant cells from the tumors spread throughout the brain by following nerve fibers and blood vessels to invade new locations. Now, researchers have learned to hijack this migratory mechanism, turning it against the cancer by using a film of nanofibers thinner than human hair to lure tumor cells away.
February 10, 2014 -- GT STRUDL, a structural engineering software system developed at Georgia Tech, has been acquired by Intergraph®, a leading producer of engineering enterprise software.
February 5, 2014 -- Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature – a property known as ballistic transport.
