Engineering articlesMagnetic, luminescent nanoparticles set new standard
Researchers at UC Davis have created a new type of nanoparticles that could be used in tests for environmental pollution or contamination of food products, and for medical diagnostics.
A bio-inspired flying robot sheds light on insect piloting abilities
Insects and other flying animals are somehow able to maintain appropriate flying heights and execute controlled takeoffs and landings despite lacking the advantage of sophisticated instrumentation available to human aviators. By characterizing the behavior of a specially designed flying robot, researchers have now been able to test a theory that helps explain how visual cues are used by insects during flight to ensure appropriate distance from the ground.
Sandia helps develop new wind turbine blade design
A new wind turbine blade design that researchers at Sandia National Laboratories developed in partnership with Knight & Carver (K&C) of San Diego promises to be more efficient than current designs. It should significantly reduce the cost-of-energy (COE) of wind turbines at low-wind-speed sites.
Researchers invent system to control and quarantine worms attacking computer networks
A new anti-worm technology developed by Penn State researchers can not only identify and contain worms milliseconds after a cyber attack, but can also release the information if the quarantine turns out to be unwarranted.
Research aims to calm your car's rattling
Researchers at Purdue University are getting close to eliminating those rattling and squeaking noises in your car's headrest and other components, major sources of consumer dissatisfaction that automakers would like to eliminate.
Mit 'optics on a chip' may revolutionize telecom, computing
In work that could lead to completely new devices, systems and applications in computing and telecommunications, MIT researchers are bringing the long-sought goal of "optics on a chip" one step closer to market.
Coated nanoparticles solve sticky drug-delivery problem
The layers of mucus that protect sensitive tissue throughout the body have an undesirable side effect: they can also keep helpful medications away. To overcome this hurdle, Johns Hopkins researchers have found a way to coat nanoparticles with a chemical that helps them slip through this sticky barrier.
Disposable sensor uses dna to detect hazardous uranium ions
Researchers at the University of Illinois at Urbana-Champaign have developed a simple, disposable sensor for detecting hazardous uranium ions, with sensitivity that rivals the performance of much more sophisticated laboratory instruments.
Photo software creates 3-d world
In the digital age, organizing a photo collection has gone from bad to worse. The saying used to be that a picture is worth a thousand words. Now the question arises: what are a thousand pictures worth? In a word, mainly a headache.
Student develops mood-sharing gadget to help computer users express their feelings
People routinely use their computers to share baby photos, corny jokes and hot music files, but an invention by Carnegie Mellon University computer science students is helping users share something more personal: their emotions.
Building a molecular computer chip
For Dr. Jerry Bernholc, a trip to Oak Ridge National Laboratory (ORNL) is like a suburbanite's trek to Costco. Bulk consumption is the name of the game. Bernholc, the Drexel Professor of Physics at North Carolina State University, spends more hours conducting research on supercomputers each year than all but a handful of U.S. scientists. Using the powerful computers – like ORNL's -- to crunch numbers is the only way to get results for the complex calculations he uses to study molecules.
Scientists develop portable generator that turns trash into electricity
A group of scientists have created a portable refinery that efficiently converts food, paper and plastic trash into electricity. The machine, designed for the U.S. military, would allow soldiers in the field to convert waste into power and could have widespread civilian applications in the future.
Cool your chips
Personal computers of the future will be so powerful that they are likely to need refrigerators to cool their chips. Now, Newcastle University is leading a project to tackle the overheating problem by miniaturising technology developed for satellites and jet fighters.
University of nevada professor demonstrates new hydrogen fuel system
Northern Nevada energy consumers can be excused if they have a sense of "sticker shock" when their power bills come due following the holiday season. Or, that they have a feeling of powerlessness as the price of gasoline climbs to $3 per gallon.
Detecting radiation on lunar and mars missions
Astronauts on lunar and Mars missions will need to continually assess their radiation risk and exposure. The faculty and midshipmen at the United States Naval Academy (USNA) are developing a small device to do exactly that, as well as alert crews during high-radiation events.
Biologically inspired sensors can augment sonar, vision system in submarines
To find prey and avoid being preyed upon, fish rely on a row of specialized sensory organs along the sides of their bodies, called the lateral line. Now, a research team led by Chang Liu at the University of Illinois at Urbana-Champaign has built an artificial lateral line that can provide the same functions in underwater vehicles.
Crime fighting potential for computerised lip-reading
Researchers at the University of East Anglia are about to embark on an innovative new project to develop computer lip-reading systems that could be used for fighting crime.
Life can be a strain
Powered by mere vibrations or the movement of magnets, novel sensors and transmitters developed by a small company in Vermont are changing the way engineers are looking at fatigue.
Researchers convert heat to electricity using organic molecules, could lead to new energy source
Researchers at the University of California, Berkeley, have successfully generated electricity from heat by trapping organic molecules between metal nanoparticles, an achievement that could pave the way toward the development of a new source for energy.
Flow of tiny bubbles mimics computer circuitry
In work that could dramatically boost the capabilities of "lab on a chip" devices, MIT researchers have created a way to use tiny bubbles to mimic the capabilities of a computer.
