Pioneering EngineeringRecent PostsWorld’s smallest ultrasound equipmentSeptember 2, 2008 | Link This | Email this | Comments (0) In case of medical emergency, having the most up-to-date technology at your disposal can mean the difference between life and death. Siemens medical Solutions’ Acuson P10 is the world’s smallest ultrasound system, and is the first pocket-sized device of its kind. Its instant accessibility is believed to have changed the way doctors are able to treat their patients, and could save the lives of many when faced with an emergency situation. While portable ultrasound equipment has been available for almost 10 years, the portability of the ...Read More Recent PostsTreetops bring “smart” materials to new heightsAugust 28, 2008 | Link This | Email this | Comments (0) Treetop canopies are the image Duke University engineers believe will help them control liquid flow in new materials. Researchers at the University are focusing their efforts on the creation of a “smart” material, which acts like human skin, delivering liquid healing agents through a network similar to blood vessels. The materials to be developed will include next generation aircraft and rocket “skins” that are able to self-repair when damaged or overheated. "Examples of this branching design tendency are everywhere in nature, from the channels making up river deltas to the architecture of the human lung, where cascading pathways of air tubes deliver oxygen to tissues," said Adrian Bejan, J.A. Jones Professor of Mechanical Engineering at Duke's Pratt School of...Read More Recent PostsStained glass air purifiers and new reaction technologyAugust 22, 2008 | Link This | Email this | Comments (0) It has recently been discovered by researchers at Queensland University of Technology (QUT) that stained glass windows which are painted with gold act as an air purifier when lit up with sunlight. These kinds of windows can be found in churches throughout Europe. “For centuries people appreciated only the beautiful works of art and long life of the colors, but little did they realize that these works of art are also, in modern language, photocatalytic air purifier with nanostructured gold catalyst,” said Associate Professor Zhu Huai Yong, from QUT’s School of Physical and Chemical Sciences in a recent news story released by the school. According to the researchers, when the gold particles found on the glass are energized...Read More Recent PostsAdvancements with metamaterials could lead to invisibilityAugust 14, 2008 | Link This | Email this | Comments (0) Invisibility, a power we all wish for, may be possible with breakthroughs from the University of California, Berkeley. Scientist at the University of California has engineered 3-D materials that are able to reverse the direction of both visible and near-infrared light. This achievement could aid in the development of higher resolution optical imaging, nanocircuits for high-powered computers, and devices that could make objects invisible to the human eye. These breakthroughs have come with the development of metamaterials, which are able to change the way light normally behaves. The key component of this is that this material has a negative refraction. This differs from natural material, which have a positive refraction; a measure of how electromagnetic waves are...Read More Recent PostsNewly developed material may lead to improved joint replacementsAugust 14, 2008 | Link This | Email this | Comments (0) Researchers have found a way to make joint replacements last longer. Scientists and engineers at the Georgia Institute of Technology have developed a new, biologically-inspired, material which may enhance tissue healing, improve bone growth around the implant, and strengthen the attachment of the implant to the bone. On average, a knee or hip replacement may last 15 years before it begins to breakdown and loosen. As a result, those who have replacement surgeries at a young age may face a second surgery to replace the initial artificial joint. The most advanced replacement surgery at this time involves the roughening of the surface of a titanium implant, or coating it with ceramic which will bond directly to the bone. The research team at Georgia Tech has developed a thin, dense polymer to be used to coa...Read More
