GTRI Agile Aperture Antenna Technology is Tested on an Autonomous Ocean Vehicle

June 18, 2013 — Antenna technology originally developed to quickly send and receive information through a software-defined military radio may soon be used to transmit ocean data from a wave-powered autonomous surface vehicle. The technology, the lowest-power method for maintaining a satellite uplink, automatically compensates for the movement of the antenna as the boat bobs around on the ocean surface.

Moving Iron in Antarctica

June 12, 2013 — Georgia Tech research indicates that diatoms stuff more iron into their silica shells than they actually need. As a result, there’s not enough iron to go around, and the added iron may stimulate less productivity than expected.

Polymer Structures Serve as “Nanoreactors” for Nanocrystals with Uniform Sizes and Shapes

June 11, 2013 — Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures – including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal nanocrystals.

Borneo Stalagmites Provide New View of Abrupt Climate Events Over 100,000 Years

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, and may help scientists assess models designed to predict how the Earth’s climate will respond in the future.

Researchers Develop Sensor System to Assess the Effects of Explosions on Soldiers

April 22, 2013 — To study the effects of improvised explosive devices on soldiers and help provide continuing treatment, researchers have developed a sensor system that measures the physical environment of an explosion and collects data that can correlate what the soldier experienced with long-term outcomes.

Midtown Alliance and Georgia Tech Partner to Create a Live-Work-Play ‘Laboratory’

April 19, 2013 — This unique partnership combines Midtown’s desirable setting with Georgia Tech’s considerable intellectual capital, research labs and incubators to develop leading-edge technology approaches to enhance the urban environment.

Georgia Tech Uses 'Big Data' Algorithm to Customize Video Game Difficulty

April 18, 2013 — Georgia Tech researchers have developed a computational model that can predict video game players’ in-game performance and provide a corresponding challenge they can beat, leading to quicker mastery of new skills. The researchers used a method called collaborative filtering, a popular technique employed by Netflix and Amazon in product ratings and recommendations. While Netflix recommends movies, the gaming model recommends the next challenge for players, adjusting game difficulty by computationally forecasting in-game performance.

Wireless "Smart Skin" Sensors Could Provide Remote Monitoring of Infrastructure

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.

Creative Assignments Lead to Teaching Success

April 15, 2013 — Steve Potter never wanted to be a conventional professor.

Bose-Einstein condensate in communication

Bose-Einstein Condensates Evaluated for Communicating Among Quantum Computers

April 11, 2013 — Physicists have examined how Bose-Einstein condensates (BEC) might be used to provide communication among the nodes of a distributed quantum computer. The researchers determined the amount of time needed for quantum information to propagate across their BEC.

Anemia Testing Technology Wins Ideas to SERVE Competition

April 11, 2013 — Anemo Check's technology to improve the accuracy and affordability of testing for anemia around the world won first place in the 2013 Ideas to SERVE (I2S) Competition at Georgia Tech Scheller College of Business.

Project Will Help Protect U.S. Forces by Simulating Hostile UAVs

April 10, 2013 — The Georgia Tech Research Institute (GTRI) is developing integrated hardware devices that simulate sensors potentially present on enemy UAVs. The technology is expected to be used to gauge the effectiveness of U.S. countermeasures against enemy drones.

Surface Diffusion Plays a Key Role in Defining the Shapes of Catalytic Nanoparticles

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.

Adhesive Differences Enable Separation of Stem Cells to Advance Potential Therapies

April 7, 2013 — A new separation process that depends on an easily-distinguished physical difference in adhesive forces among cells could help expand production of stem cells generated through cell reprogramming. By facilitating new research, the separation process could also lead to improvements in the reprogramming technique itself and help scientists model certain disease processes.
