By now, many readers are probably familiar with the da Vinci
robotic surgery system. It allows a seated surgeon, using a 3D display and hand controls, to operate on a patient using robotic arms equipped with surgical instruments. Not only does the system allow for more laparoscopic surgery (in which surgical instruments access the inside of the patient’s body through small incisions, instead of one large opening), but it even makes it possible for the surgeon and the patient to be in separate geographical locations. Now, a researcher at the Netherlands’ Eindhoven University of Technology has developed a similar system, designed specifically for operations on the eye.
Most people who have sweated it out in the gym trying to add a bit of muscle definition to their bodies will know just how difficult such a task is, but trying to grow muscle tissue with a real muscle structure complete with blood vessels in the laboratory has proven to be an even more difficult brief for researchers. Now a team from the Eindhoven University of Technology (TU/e) has done just that, paving the way for the creation of engineered muscle tissue that can be implanted into patients who have lost muscle tissue through accidents or surgery.
Not only is the old inflatable-cuff-around-the-arm an uncomfortable way of having one's blood pressure
measured, but it turns out that it doesn't always provide enough information, either. If a physician wishes to check for vascular diseases such as atherosclerosis, thrombosis or aneurysms, for instance, they're going to want to know how the blood is flowing in areas besides the patient's arm. Because the cuff works by temporarily stopping the blood flow, however, it's not going to work too well on a patient's neck or torso. Fortunately, scientists from The Netherlands' Eindhoven University of Technology (TU/e) have discovered that ultrasound can be used instead, and that it provides more details.
If there’s one big environmental concern surrounding power plants that burn material such as coal in order to produce power, it’s the amount of carbon dioxide that they release into the atmosphere. Various experimental technologies
have been developed for removing most or all of the CO2 from smokestack effluents, although no one system appears to have been universally accepted as of yet. One technology that shows some promise, and that could perhaps be used in conjunction with other systems, is called Chemical Looping Combustion (CLC). Norwegian research group SINTEF is now building a special new type of CLC system, for use in the DemoCLOCK pilot project, to be installed at Spain’s Elcogas Puertollano power plant.
is certainly one of the big candidates when it comes to finding cleaner fuels to replace petroleum. While it only produces water when burnt as fuel, the process of obtaining hydrogen from natural gas is not quite so eco-friendly – it consumes a lot of energy, and creates carbon dioxide. Now a new process being developed at the Netherlands' Eindhoven University of Technology (TU/e) promises a much more efficient, innocuous alternative.
With its two chief properties of excellent electrical conductivity and optical transparency, indium tin oxide (ITO) can be found in transparent conductive coatings for displays found in all kinds of products, such as TVs, mobile phones and laptops, and is also used as a transparent electrode in thin-film solar cells. Unfortunately indium is a rare metal and available supplies could run out in as little as ten years. This has prompted researchers to search for alternatives with some success already reported using carbon nanotubes
and copper nanowires
. The latest ITO replacement material also uses carbon nanotubes, as well as other commonly available materials, and is environmentally friendly.
Last December at the Future of Electric Vehicles
conference in San Jose, a representative from The Netherlands’ Eindhoven University of Technology presented research that his institution had been doing into a novel type of electromagnetic vehicle suspension. Now that a test car equipped with the suspension is about to appear at the AutoRAI exhibition in Amsterdam, the university has released some more details about the technology. For starters, it is claimed to improve the overall ride quality of cars by 60 percent.
