|Mark your calendars! The 12th annual Ames Laboratory Employee Benefit Holiday Auction will be held on Tuesday, Dec. 10.|
|Two Ames Laboratory researchers, Alan Goldman and Mark Gordon, were among 39 faculty and staff honored by the College of Liberal Arts and Sciences at Iowa State University for their accomplishments. The recipients were recognized at the Fall Liberal Arts & Sciences Faculty/Staff Convocation on Wednesday, Sept. 11, 2013.|
Ames Laboratory cyclists completed the National Bike Challenge with a total of nearly 16,500 miles. Forty-six riders contributed to the total which placed the Lab fourth among the 62 Iowa teams registered for the event and 88th nationally out of 2,144 teams. Top riders for the Lab were Rebecca Shivvers, Gary Walter and Kyle Marchuk.

Paul Canfield, scientist at the U.S. Department of Energyâ€™s Ames Laboratory and Distinguished Professor of Physics and Astronomy at Iowa State University, has been selected by the American Physical Society for the 2014 David Adler Lectureship Award in the Field of Materials Physics.
Recent estimates state that the supply of food should increase by 50% in the next 40 years to accommodate the changes in demographics and eating habits. We are at a remarkable juncture where (i) the price of oil and nitrogen-based fertilizers is expected to increase, (ii) the long term availability of phosphorus for fertilizers is in doubt, (iii) the erosion of soil is reducing yields, and (iv) climate change brings extreme weather that impacts crop survival and productivity.
Unique properties (e.g., rubber elasticity, viscoelasticity, folding, reptation) determine the utility of polymer molecules and derive from their morphology (i.e., one-dimensional connectivity and large aspect ratios) and flexibility. Crystals do not display similar properties because they have smaller aspect ratios, they are rigid, and they are often too large and heavy to be colloidally stable. These limitations are not fundamental and they can be overcome by growth processes that mimic polymerization.
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.
