New insights into how materials transfer heat could lead to improved electronics
Researchers have published new insights into how materials transfer heat, which could lead eventually to smaller, more powerful electronic devices.
Change in cycle track policy needed to boost ridership, public health
Bicycle engineering guidelines often used by state regulators to design bicycle facilities need to be overhauled to reflect current cyclists'' preferences and safety data, according to a new study. They say that US guidelines should be expanded to offer cyclists more riding options and call for endo...
Engineers design, test taller, high-strength concrete towers for wind turbines
Engineers have designed and tested a concept for concrete towers to replace the steel towers used for wind turbines. The concrete towers could be a practical way to raise turbine towers from today''s 80 meters to the better winds at 100 meters or higher.
Nanoscavengers could usher in next generation water purification
A new synthetic nanoparticle could disinfect, depollute, and desalinate contaminated water and then get removed magnetically. This improves upon existing technologies through ultraresponsiveness to magnetism.
How long do insects last?
Researchers have shown that although insects are made from one of the toughest natural materials, their legs and wings can wear out over time.?
Potential of best practice to reduce impacts from oil and gas projects in the Amazon
Hydrocarbon exploration and production continues to press into the most remote corners of the western Amazon, one of the most biologically and culturally diverse zones on Earth. A new best practice framework that combines technical engineering criteria with ecological and social concerns could reduc...
Bug''s eye inspires hemispherical digital camera
Inspired by the complex fly eye, a research team has developed a hemispherical digital camera with nearly 200 tiny lenses, delivering exceptionally wide-angle field of view and sharp images. The new camera -- a rounded half bubble, similar to a bulging fly eye -- has 180 microlenses mounted on it, a...
New measurement tool is on target for the fast-growing MEMS industry
As markets for miniature, hybrid machines known as MEMS grow and diversify, researchers have introduced a long-awaited measurement tool that will help growing numbers of device designers, manufacturers and customers to see eye to eye on eight dimensional and material property measurements that are k...
Researchers tackle collapsing bridges with new technology
Researchers have proposed a new technology that could divert vibrations away from load-bearing elements of bridges to avoid catastrophic collapses. The "wave bypass" technique has many similarities to those being used by researchers looking to create Harry Potter-style invisibility cloaks, which exp...
Zinc: The Goldilocks metal for bioabsorbable stents?Stories 1 - 10 of 415
Stents can be lifesavers, propping open blood vessels to allow for healthy blood flow. But the longer a stent is in the body, the greater the risk of side effects such as inflammation and clotting. Designing a stent that will dissolve harmlessly after the artery has healed has been a challenge. Now ...
