Science Highlights
Predictive models of environmental reaction kinetics made more accurate, scalable
Scaled up
Released: August 08, 2013
Integrated computational and experimental studies show that predictive models of biogeochemical interactions in soils are more accurate and scalable if they consider the reaction chemistry in distinct soil pore structures.
Sulfide and iron work together to reveal a new path for radionuclide sequestration
Sulfur cleans up
Released: July 31, 2013
By employing nano zerovalent iron to promote sulfide generation in technetium (Tc)-contaminated groundwater, scientists offer a fundamental geochemical understanding of Tc sequestration and a potential new remediation strategy.
Scientists gain first quantitative insights into electron transfer from minerals to microbes
Tunable transfer
Released: July 30, 2013
Scientists have gained the first quantitative insights into electron transfer from minerals to microbes by studying that transfer in a nature-inspired, protein and iron-based 'tunable' nanoparticle system.
New insight into Salmonella infection revealed by top-down proteomics strategies at EMSL
The switch
Released: June 26, 2013
A first-of-its-kind molecular switch has been discovered in the food-poisoning bacterium Salmonella Typhimurium. Reported in PNAS, this discovery was made possible with the help of top-down proteomics strategies at EMSL.
New study reveals chemical transformations of ambient organic aerosols
Agents of change
Released: June 14, 2013
Scientists used EMSL’s nano-DESI and mass spectrometry capabilities to analyze the molecular composition of atmospheric organic aerosols, or OA, and uncovered a new method for investigating OA that may lead to more precise climate models.
First view of micellar bundles revealed by EMSL electron microscopy tools, techniques
Micelle microscopy
Released: May 28, 2013
As part of a study, reported in PNAS, to better understand how to tailor micelles—whose applications range from oil recovery to drug delivery—the first high-resolution view of micellar bundles formed from a solution of wormlike micelles was made possible by EMSL.
Biofilms move electrons long distances across two distinct layers, even under starving conditions
Long distance
Released: May 23, 2013
Bacteria can move electrons at least half a millimeter across a scaffolding made by themselves, of themselves, even under starving conditions—this new finding by EMSL staff and users challenges conventional wisdom.
EMSL’s Chinook provides a new angle for validating pore-scale flow simulations
Go with the flow
Released: May 16, 2013
Scientifically, simply “going with the flow” can have great implications. In natural porous media, such as soils, subsoil vadose zones, and aquifer systems, accurately simulating detailed flow velocity fields can elucidate a multitude of macroscopic phenomena.
