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.
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.
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.
EMSL tools reveal morphology, growth mechanisms of precipitates from scCO2 storage
Rods and rosettes
Released: April 16, 2013
A study that revealed new details about the geochemistry of scCO2 underground storage, made possible with EMSL’s helium ion microscope, is featured on the April 2013 cover of Microscopy and Microanalysis.
Micromodels redefine how bubbles characterize CO2 gas flow
Breaking down the bubbly
Released: March 20, 2013
EMSL's Microfabrication and Subsurface Flow and Transport capabilities helped scientists model how mobile bubbles in reservoir storage conditions create a flow barrier from exsolved carbon dioxide, which shows promise for future geological sequestration.
Nanoclusters in steel add strength, stability under irradiated conditions
A steel trap
Released: March 05, 2013
Scientists using various analysis tools at EMSL to examine and quantify complex nanoclusters within oxide dispersion strengthened steels have a new view of how these metal materials display resistance and stability under a range of irradiation conditions.
