Nitinol Devices and Components recently had an idea for changing the design of stents used to open blocked blood vessels: Make them out of a shape-memory alloy rather than stainless steel. Question: Would the alloy stand up to the rigors of the human body, including the average 40 million beats the human heart has per year?
Prototype testing to see if it would work would have been tough. So Nitinol used Abaqus software to simulate the behavior of the material within a blood vessel. Result: the material acted as expected. The stents are available now and, says Nitinol, working well.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
