More than 1,000 tons (2.2 million pounds) of titanium devices are implanted in patients worldwide every year with joint replacements one of the more common procedures. Light, strong and totally biocompatible, titanium is one of the few materials that naturally match the requirements for implantation in the human body. Researchers have now developed an improved coating technique that could strengthen the connection between titanium joint-replacement implants with a patient’s own bone. The stronger connection – created by manipulating signals the body’s own cells use to encourage growth – could allow the implants to last longer.  Read More

Georgia Tech's David Roberts with one of the laser testing glass boards

Traditionally, when someone wished to measure the total power delivered by a laser beam, they had to use something called a ball calorimeter. As the laser heated the interior of the ball, temperature readings would be taken. Now, however, a system has been created that utilizes reusable glass boards. It can measure a laser's total energy along with the total power and power density anywhere inside the beam more than one hundred times per second. It should be a boon to developers of high-energy laser weapons, as it will reduce the time required for testing, and get the weapons in the field faster.  Read More

Image of the Centenial Park Granite shown in the Kamra AR mobile browser

Researchers at the Georgia Institute of Technology have announced the availability of a developer preview of Kamra, a mobile browser based on open web standards. The first augmented reality browser for the KHARMA (KML/HTML Augmented Reality Mobile Architecture) development platform, Kamra offers users multiple simultaneous augmented content overlayed on top of a live video scene.  Read More

The tubular steel 'space frame' of the Ultra II is welded together

Casualties in Iraq from Improvised Explosive Devices (IEDs) have dropped as the number of Mine Resistant Ambush Protected (MRAP) vehicles has increased, but with roadside bombs still responsible for the majority of casualties to coalition forces in Afghanistan, there is a need for a smaller, more nimble version more suited to its rugged, mountainous terrain. A new concept that would see military vehicles built around a protected personnel compartment and use a sacrificial “blast wedge” to absorb energy could improve safety for the occupants of future light armored patrol vehicles.  Read More

Zhong Lin Wang holds a prototype three-dimensional solar cell that could allow PV systems ...

The photovoltaic (PV) panels adorning the rooftops of buildings around the world have become a visible sign of the shift towards environmentally friendly solar power. Now researchers have developed a new type of three-dimensional PV system using optical fiber that promises solar generators that are foldable, concealed and mobile, meaning they could be hidden from view and leave rooftops panel-free.  Read More

A 'Smart Trash' concept receptacle with scanner to keep track of trash

If the benefit to our environment isn’t enough to get some people to recycle, Georgia Tech’s Valerie Thomas has come up with the concept of offering a cash incentive enabled by “Smart Trash”. The concept involves a scanner integrated into a trash receptacle that automatically records what is being disposed of using Universal Product Codes (UPC) or radio frequency identification (RFID) tags attached to the trash. This would not only allow recyclers to better sort the waste but could also provide a cash back channel to consumers recycling goods of value.  Read More

Graphene, the one-atom-thick gauze of carbon atoms resembling chicken wire first isolated in 2004, continues to find new and wondrous applications. It has already been used to create the world’s smallest transistor and now researchers at the Georgia Institute of Technology have experimentally demonstrated the potential for graphene to replace copper for interconnects in future generations of integrated circuits.  Read More

Silicon pyramid structures etched for two minutes using hydrogen fluoride/hydrogen peroxid...

Solar power from photovoltaic cells are widely recognized as an integral part of a clean green future, and any development that can make these cells more efficient, no matter how small, assists in making this future a reality. A team of researchers at Georgia Tech have developed a surface treatment that boosts the light absorption of silicon photovoltaic cells by trapping light in three-dimensional structures and by making the surfaces self cleaning.  Read More

Jaime Oliver and his Silent Drum

New technology means new ways to create and express music and new types of interfaces that broaden the definition of a "musical instrument" way beyond traditional parameters. Georgia Tech’s Center for Music Technology seeks to recognize the creators of new musical instruments with the Guthman Musical Instrument Competition. The first winners of the competition include a robotic guitar, SLABS touch pad and a Silent Drum that generates sound by manipulating the elastic spandex head of a drum shell.  Read More

Professor Karsten Schwan

Having crashed through the petaflop barrier of a thousand trillion calculations per second back in June, scientists are continuing work into achieving the next benchmark in supercomputer performance - exascale computing. Georgia Institute of Technology's Professor Karsten Schwan is one of two scientists working in the field to receive a 2008 HP Labs Innovation Research Award to further research into solving the problems thrown-up by computing on this scale.  Read More
