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.
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.
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.
Protein signaling between soybean root hairs, bacteria reveals core cellular processes
Orchestrating change
Released: December 12, 2012
Proteomics tools at EMSL helped characterize soybean root hairs and their responses to symbiotic rhizobial colonization and infection. These studies could help scientists redesign plants and improve crop yields, benefitting both food and biofuel production.
New bacteria, potential carbon cycling, bioremediation roles reported in Science
Brand new genes
Released: November 06, 2012
Proteomics experts and resources at EMSL contributed to a study published in Science centered on the discovery of new bacteria and the metabolic roles, such as carbon cycling, of bacteria in the environment.
In silico, in vivo, in vitro approach opens doors for nanoparticle-based drug discovery
Model health
Released: October 09, 2012
Using computational tools to complement experimental results offers an unprecedented atomic-level understanding of how gadolinium metallofullerenol nanoparticles inhibit the growth and metastasis of pancreatic tumors.
