Thomas Lograsso has been named Interim Deputy Director of the U.S. Department of Energyâ€™s Ames Laboratory. The appointment is for one year. Lograsso replaces Bruce Harmon, who stepped down from the position of Ames Laboratory Deputy Director on September 1 to return to research and teaching at Ames Lab and Iowa State University.
Iowa Powder Atomization Technologies, a start-up company based on technology developed at the Department of Energyâ€™s Ames Laboratory, has won the 2012 John Pappajohn Iowa Business Plan Competition. The competition honors top business plans of companies in business for four years or less, with an aim of stimulating business development. The prize includes $25,000 in seed money.
The physical properties and performance of materials depends on their structure as much as their composition. For example, a relatively minor change in interface chemistry improves the power efficiency of a prototype PbS quantum dot-based solar cell by an order of magnitude.
Despite this premise and the remarkable advances in materials processing and chemistry, we still cannot design and manufacture materials with a monodisperse and controllable micro- and nano-structure in a way that is scalable, versatile, inexpensive and practical.
Development for Sn-Ag-Cu (SAC) Pb-free Solders for Broad Application and High Reliability in â€œGreenâ€ Electronic Assembly
Great strides have been made in the plant sciences through high-throughput DNA sequencing and analysis of plant genomes. The challenge now is to develop analogous high-throughput technologies to analyze a plant's biochemical makeup, which is the key to utilizing genomics to improve and develop new crops.
Bio-oil, obtained from fast pyrolysis, is considered to be a promising renewable energy that might replace petroleum to improve the sustainability, national security, domestic economy and diversity of transportation fuels.
Developing a Sustainable Catalyst Toolbox
Work in the Woo Group is directed towards developing green chemistry approaches to catalytic reactions and sustainable technologies. Students will learn and engage in practices that develop more economical and greener processes by utilizing environmentally friendly transition metal complexes and solvents as substitutes for commonly used heavy metal compounds and organic media.
Bacteria contribute significantly to our well-being. They constitute our microbiome that is involved in digesting food and delivering information to the brain regarding the food content. They are essential for degrading materials in the soil and waters of our planet to maintain a stable and healthy environment for us.
The main objective of the Smith research group is to demonstrate Raman spectroscopy analyses of biomass, enzymatic catalysis, and thin films. This objective is accomplished through a combination of analytical measurements, instrument and method development. Our work supports the use of biomass as a feedstock for renewable fuels and commodity chemicals through rapid, non-invasive characterization of biomass composition and conversion.
