Ghassan E. Jabbour is a University of Arizona professor developing an inkjet printing process that produces photovoltaic devices such as solar cells. He uses digitized images on a computer and sends them to a printer that sprays an organic solution onto an electrically conductive surface. He describes the printed product as a self-illuminated photograph. "The new process uses inkjet to vary the conductivity of the conductors," says Jabbour. "Basically, we design an electronic circuit, scan it to a computer, then send it to the printer." He programmed the printer to interpret colors and convert them to particular chemicals that produce predetermined reactions. "We do some chemistry that allows us to control where we want a lot of electrons and where we don't want electrons." His self-illuminated photographs print in visible colors, but he can also print in colors in the infrared wavelength range that are invisible to the naked eye. For more information, go to www.ua.edu.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
