A painting process developed for the Mercedes A-Class passenger car is not only environmentally friendly but also quick and cost-efficient. The process, which is the result of a collaboration between Mercedes-Benz, BASF Lacke + Farben, and Durr Systems, involves new materials as well as optimized production systems. Like other state-of-the-art automotive paint systems, four coats are involved. The composition of the first coat on the Mercedes A-Class, however, is completely lead-free, and the second coat is less than half the thickness of conventional paint processes (15 micron instead of 40 micron). This, says Konrad Ortlieb, Durr R&D manager, "results from a special formulation of primer and by maintaining extreme control of the spray equipment to ensure an even application of paint." The third color coat is conventional but the fourth represents a world "first," according to Ortlieb. Composed of a powder slurry, this fourth clear coat is solvent-free. "Other companies have developed water-based clear coats, but there is always a small residue of solvent. Our slurry solution has none," he claims. An added advantage of the BASF/Durr process is that the three paint coats are applied wet-on-wet, eliminating the need for an inter-coat baking stage, thereby saving time.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
