Shaken Up: Atomic Force Microscopy Shows Liquids Adjust Viscosity when Confined, Shaken

April 29, 2008 -- New research shows that when water is confined to a small space, it behaves like a gel. Then, when shaken, it becomes fluidic and exhibits the same structural and mechanical properties as water in a bottle. The study "“ the first to use an atomic force microscope to measure the viscosity of confined fluids "“ revealed that these liquids can respond and modify their viscosity based on environmental changes.

OLED Encapsulation: New Sealing Process Reduces Water Intrusion and Increases Device Lifetimes

April 23, 2008 -- Researchers have developed an improved organic light emitting diode (OLED) sealing process to reduce moisture intrusion and improve device lifetime. They are using advanced ion assisted deposition to deposit a high-density, pinhole-free thin silicon oxynitride (SiON) film on the OLED surface. The process can be completed at room temperature, which keeps the organic material intact.

Characterizing Materials: Fast AFM Probes Measure Multiple Properties of Biomolecules or Materials Simultaneously

April 16, 2008 -- Researchers have developed novel atomic force microscopy probes that can quickly and simultaneously measure biomolecule or material properties including adhesion, stiffness, elasticity and viscosity, in addition to the standard AFM topography scan.

Fate and Function: Molecule Delivery Method Improves Embryonic Stem Cell Differentiation

April 9, 2008 -- New research shows that delivering molecules within aggregates of embryonic stem cells via biodegradable microspheres enhances the efficiency and purity of differentiation.

Supporting the Army: GTRI’s Huntsville Research Laboratory Celebrates 30 Years of Service

Research Horizons Winter/Spring 2008 -- The Georgia Tech Research Institute’s (GTRI) Huntsville Research Laboratory (HRL) has observed a major anniversary: 30 years of service at the Redstone Arsenal in Huntsville, Ala., supporting U.S. Army missile technology.

Georgia Interoperability Network: Georgia Tech Helps Craft a Swift, Sure Emergency Network

Research Horizons Winter/Spring 2008 -- Engineers from the Georgia Tech Research Institute (GTRI) are participating in the development of a statewide system that will connect existing radio communications systems in most Georgia counties and certain state agencies to an Internet protocol (IP)-based network.

Carbon Capture: Low-Cost Reusable Material Could Facilitate Capture of Carbon Dioxide from Power Plants

March 7, 2008 -- Researchers have developed a new, low-cost material for capturing carbon dioxide (CO2) from the smokestacks of coal-fired power plants and other generators of the greenhouse gas. Produced with a simple one-step chemical process, the new material has a high capacity for absorbing carbon dioxide – and can be reused many times.

Forget Your Meds? Sensor Necklace Aims to Increase Drug Compliance Among Elderly and Clinical Trial Participants

March 5, 2008 -- Researchers now have a possible solution for the one in three adults who fail to take their medicines as prescribed by their doctors, as well as for everyone else who occasionally forgets: a sensor necklace that records the exact time and date when specially-designed pills are swallowed, and reminds the user if any doses are being missed.

Convergence of Bioscience and Engineering: Biomedical Engineering Department Marks 10th Anniversary

Research Horizons Winter/Spring 2008 -- When Georgia Tech President Wayne Clough broke ground on the first building of the new Biotechnology Complex in May 1998, the shovel heralded more than just new brick and glass. The four new structures built around the quadrangle became the physical manifestations of one of the most dramatic changes in Georgia Tech’s nearly 125-year history: the convergence of bioscience and engineering.

Georgia Tech and Emory University Lead Three Nanomedicine Centers

Research Horizons Magazine Winter/Spring 2008 -- The Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University is the only academic department in the United States to host three National Institutes of Health (NIH) centers focused on nanomedicine.
