This morning’s newspapers are full of stories of deep budgets that are sure to affect funds for scientific research. And buried deep inside is a story of a call by leading American scientists to research and develop new sources for energy-critical materials, such as lithium and tellurium.
There are two issues. Demand is rising for these materials to produce lighter weight vehicles, batteries for electric cars, thin film solar cells, and a variety of other emerging energy-related applications. At the same time, the largest known source of these materials, China, is taking steps to shut off the spigot.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
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.
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).
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
