University of Arkansas researchers combined an alkali with heat to produce ceramic nanowires that coat titanium medical implants, creating more biocompatible surfaces. Muscle tissue often does not adhere well to the smooth surfaces of titanium, leading to failure after about ten years. In experiments with mice, muscles adhere to the new nanowire compound in about four weeks. "We can control the length, the height, the pore openings and the pore volumes within the nanowire scaffolds" by varying the time, temperature and alkali concentration in the reaction, said Z. Ryan Tian, assistant professor of chemistry and biochemistry in the J. William Fulbright College of Arts and Sciences. "This process is also extremely sustainable," requiring only that the device be rinsed in reusable water after the heating process.
A new white paper by the Association for Advancing Automation says that increases in industrial robot shipments correlates positively with increases in US job growth based on Bureau of Labor statistics. The result could be new types of manufacturing and engineering jobs.
Ford will be the first automaker to commercially use Alcoa's tough & fast Micromill aluminum alloy process and materials, debuting on several 2016 F-150 truck components. Alcoa will also license its Micromill process and materials technology to Danieli Group.
