The Z-machine at Sandia National Laboratory, a former dark horse among accelerators meant to produce conditions required for nuclear fusion, is doing much better now, thank you. Researchers increased the machine's X-ray power output by nearly 10 times in the last two years. The most recent advance resulted in an output X-ray power of 290 trillion watts--about 80 times the entire world's output of electricity. The increased power will be a major contribution to the Department of Energy's (DOE) science-based approach to stockpile stewardship. This program dictates that DOE must use giant computing and laboratory experimentsto sustain the nation's nuclear stockpile without above- or below-ground tests. FAX (505) 844-6367.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
