O'DONNELL Of The Reowtek'b Ameii Bi'mal' Amet, I. A sign In Iver Anderson's office at the Ames Laboratory's Metals Development building Is a reminder of the timeless nature of his work. It's an old handbill advertising a blacksmith's machine repair services. Like the blacksmith of old, Anderson works with metal. But the high-tech high-tech high-tech processes he puts it through are light years ahead of the anvil and hammer. Anderson, 43, is a leader In finding new ways to produce fine metal powders. His research at the lab, a U.S. Department of Energy facility that is operated by Iowa State University, has led to a lead-free lead-free lead-free solder solder that could set the industry standard and new methods for producing powerful magnets. His processes could even be an important step on the road to the high-efficiency high-efficiency high-efficiency high-efficiency car of the future. His research is at the edge of the future, but Anderson's fascination with metals is as old as human history. "In a word, it's neat," said Anderson, who is also an adjunct professor of materials materials science and engineering at ISU. "I get to play with liquid metal. It looks tantalizing-ly tantalizing-ly tantalizing-ly like water that you could touch with your finger ... but because it's very dense, it flows in different ways than water-Anderson water-Anderson water-Anderson grew up in the copper mining country of Michigan's upper-peninsula, upper-peninsula, upper-peninsula, surrounded by mountains of tailings and startled by the occasional rumble of an abandoned mine tunnel collapsing. The industry got him interested in geology, but Anderson's father, engineering professor Jean Anderson, believed metallurgy was a better match for his son's interests. "It always amazes me how he put his finger finger on it," Iver Anderson said.
