Mesoporous Block Copolymer Membranes for Bioseparations

We are investigating innovative membrane design to be applied to a variety of bioseparations relevant to the metabolic production of high-value chemicals. The membranes consist of percolating networks of 5-20 nm diameter pores in a block polymer matrix, fabricated via self-assembly. The surface-to-volume ratio is ~1000 mml-1, and consequently transport will be dominated by surface interactions. Accordingly, pore-wall functionalization should tune the selectivity to promote or retard the transport of specific classes of chemicals. 

3D printing comes to Critical Materials Institute

3D printing technology, which has captured the imagination of both industry and consumers, enables ideas to  move quickly from the initial design phase to final form using materials including polymers, ceramics, paper and even food. But the Critical Materials Institute (CMI) will apply the advantages of the 3D printing process in a unique way: for materials discovery. By doing so, researchers can find substitutes to critical materials-- ones essential for clean energy technologies but at risk of being in short supply.

Ames wins 2014 Middle School Science Bowl

Image Ames Middle School made a clean sweep of the 2014 Ames Laboratory Regional Middle School Science Bowl here Saturday. They won all three of their morning qualifying matches, then won four matches in the championship round to take the title. They will also join the Ames High School team in representing the Region at the Department of Energy’s National Science Bowl in Washington, D.C. April 24-27.

Raising Readers holding Step into Storybook event March 29

Ames Lab employees will have the chance to see their generosity in action when the Raising Readers in Story County hosts it's annual Step into Storybooks event on March 29. This year's theme is Exploring Science through Books and will feature hands-on science stations and the first 300 children to attend will receive a free science picture book, funded through the proceeds of the 2012 Ames Lab Holiday auction.

The Clean Plate Club

Image Childhood obesity in this country is of growing concern. So much so, that our First Lady has made it her priority to lead our nation’s kids in healthy eating and exercising. According to the CDC, childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years. Here are some tips to help them eat right, get more exercise and live healthy!
