Materials are the backbone of technology. Whenever a materials displays a new function, it transforms society: biodegradable scaffolds will enable the regeneration of tissues, shape memory alloys enabled stents that repair clogged vessels, superhydrophobic surfaces will prevent ice deposition on surfaces, ultrahard coatings will enable plastic electronics and reduce waste of materials and energy by abating friction and wear.

For a number of animals, including birds, fish and mammals, there is evidence that magnets are used for orientation. However, little is known about how these organisms build these magnets. For magnetotactic bacteria we have isolated a protein that will drive the formation of magnetic particles. We are using this protein to discover how these bacteria produce magnets by the process called biomineralization.
This project will investigate the relationship between real wind speed data (and potentially power data) collected at wind turbines, and the power estimates provided by models that use estimated wind resource, wake models and turbine power curves to predict power output. Different wake models will be investigated to see if some are more effective at predicting results than others. Any variance from real data in the predictions will be traced to the three factors modeled, to see if one plays a larger role than the others.

CNBC reporter Eric Rosenbaum talks with Ames Laboratory researchers Karl Gschneidner and Bill McCallum on the scarcity of rare-earth metals and what the Critical Materials Institute hopes to do about the problem, including finding substitute materials and using more plentiful cerium in place of dysprosium.
This three-day course provides hands-on training focused on the basic concepts and techniques for analyzing forensic digital images.
|A number of Ames Laboratory staff have been selected to receive research and teaching awards from Iowa State University.|
