This inorganic, water-dispersed, alumina-filled ceramic adhesive is made to bond and seal thermocouple probes in high-temperature environments up to 3,200F (1,760C). It can be put on with a brush, spatula or syringe, and cures in one to two hours at 700F. It gets stronger the hotter it gets, with tensile-shear strength of 900 psi through curing at 1,000F. It's an inert, chemically-resistant adhesive that won't outgas in ultra high vacuum, and, as an electrical insulator, has a resistivity of 109 Ù-cm and a dielectric strength of 250 V/mil. It can also be used in the assembly of dense ceramic components used in ultra-high vacuum equipment, repairing of ceramic saggar plates, and bonding and coating of platinum/rhodium resistance wires to aluminum oxide heaters and other applications.
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).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
