Real-world materials are usually messier than the idealized scenarios found in textbooks. Imperfections can add complications and even limit a material s usefulness. To get around this, scientists routinely strive to remove defects and dirt entirely, pushing materials closer to perfection. Now, researchers at the University of Illinois at Urbana-Champaign have turned this problem around and shown that for some materials defects could act as a probe for interesting physics, rather than a nuisance.
NIST awards nearly $4M to support metals-based additive manufacturing
The US Department of Commerce’s National Institute of Standards and Technology (NIST) has awarded nearly $4 million in grants to help accelerate the adoption of new measurement methods and standards to advance US competitiveness in metals-based additive manufacturing (AM).
Additive manufacturing typically creates parts and components by building them layer by layer, based on a 3D computer model that is virtually sliced into many thin layers. Metals-based additive processes form parts by melting or sintering material in powder form. The process offers advantages such as reduced material waste, lower energy intensity, reduced time to market and just-in-time production.

Sec. Pompeo at Georgia Tech:
As President Cabrera said, I graduated from the United States Military Academy at West Point studying engineering, although I joke, don’t drive across a bridge that I had anything to do with. It’s been an awfully long time.
Some of my classmates ended up in the Army Corps of Engineers. I happened to command a cavalry unit. But I can tell you math matters an awful lot when you’re bore-sighting the cannon of an M1A1 tank.
And I’ll say, too, even the State Department – you talked about people leaving this institution going on to careers in diplomacy. One of the first things that came across my desk as Secretary of State was there was an important dam across a bridge in Iraq and it was in trouble, and we were trying to figure out could we figure out how to save it, could we figure out how to deploy resources in a difficult place. And we had the best engineers in the U.S. Government, some of whom worked for me at the United States Depart
