Harvesting Electricity: Triboelectric Generators Capture Wasted Power
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.
Clinical Trial Shows Tongue-Controlled Wheelchair Outperforms Popular Wheelchair Navigation System
In a new clinical trial, individuals with paralysis were able to use a tongue-controlled technology to access computers and execute commands for their wheelchairs at speeds that were significantly faster than those recorded in sip-and-puff wheelchairs, but with equal accuracy. This study is the first to show that the wireless and wearable Tongue Drive System outperforms sip-and-puff in controlling wheelchairs.
Scientists Work to Engineer an Injectable Therapy for Rotator Cuff Injuries
Researcher are attempting to engineer an injectable therapy for the shoulder’s supraspinatus tendon, a rotator cuff tendon that is commonly torn in sports. When the tendon is damaged, the body makes things worse by activating enzymes that further break down the tendon. The scientists hope to develop an injectable compound that would deliver an inhibitor capable of blocking these enzymes, thereby reducing the severity of the injury or even healing the tissue.
Sticky Business: Magnetic Pollen Replicas Offer Multimodal Adhesion
Researchers have created magnetic replicas of sunflower pollen grains using a wet chemical, layer-by-layer process that applies highly conformal iron oxide coatings. The replicas possess natural adhesion properties inherited from the spiky pollen particles while gaining magnetic behavior, allowing for tailored adhesion to surfaces.
Evidence Found for Granite on Mars
Large amounts of a mineral found in granite, known as feldspar, were found in an ancient Martian volcano. The location of the feldspar also provides an explanation for how granite could have formed on Mars, according to a new study in Nature Geoscience.
Optimization Modeling Helps Control Electricity Supply Continuity in Brazil
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.
November 11, 2013 – A pair of microbes on the ocean floor “eats” methane in a unique way, and a new study provides insights into their surprising nutritional requirements. Learning how these methane-munching organisms make a living in these extreme environments could provide clues about how the deep-sea environment might change in a warming world.
November 5, 2013 — Pfizer Inc. recently worked with researchers at the Georgia Tech Research Institute (GTRI) to develop an easy-to-open and child-resistant container and cap to dispense one of its rheumatoid arthritis medicines. The square bottle with round, blue closure recently received the ease-of-use commendation from the U.S. Arthritis Foundation.
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.
October 16, 2013 – Researchers have developed a new technology to sort human cells according to their stiffness, which might one day help doctors identify certain diseases in patients, according to a new study.
October 15, 2013 – As the newly appointed Chief Engineer for pediatric technologies for the Georgia Tech-Children’s Healthcare of Atlanta partnership, solving real world problems for clinicians by leveraging the engineering expertise on Georgia Tech’s campus is Leanne West’s new job.
October 15, 2013 — Researchers are currently assessing the usability of electronic flight bags based on tablet computers for Air National Guard pilots. Electronic flight bags could improve safety, operational effectiveness and efficiency for crew members, plus save paper and printing costs.
October 10, 2013 – A new study suggests that ‘unpredictable climate variability’ behaves in a more predictable way than previously assumed.
October 7, 2013 – For years scientists have been working to fundamentally understand how nanoparticles move throughout the human body. One big unanswered question is how the shape of nanoparticles affects their entry into cells. Now researchers have discovered that under typical culture conditions, mammalian cells prefer disc-shaped nanoparticles over those shaped like rods.
