The Copper Mountain Mine is located 20 km south of Princeton, British Columbia. The 2016 production target is 80 million pounds of copper (+/– 5%), plus gold and silver byproducts. This video shows the mining process, and all the trucks and equipment needed to dig out the ore and turn it into copper.
Although stabilized alloys do not require high-temperature annealing to avoid intergranular corrosion, the stress-relieving temperature exerts an influence on the general corrosion resistance of these alloys.
The Autonomous Materials Systems Group at the Beckman Institute for Advanced Science and Technology, Urbana, Ill., recently devised a way to identify microscopic damage in polymers and composites by incorporating microcapsules containing materials that fluoresce under stress.
Andy Klesh of the Jet Propulsion Lab welcomes us to the cleanroom to talk about how satellites smaller than a briefcase could one day explore the chemistry of alien moons and planets.
For all the promise they have shown in the lab, polymer solar cells still need to “get on a roll”—like the ones employed in printing newspapers so that large sheets of acceptably efficient photovoltaic devices can be manufactured continuously and economically.
