Welcome to Currents


Welcome to Currents. Every six to eight weeks, this e-newsletter will feature the latest research from PNNL, discuss how we are working with other labs and universities, and highlight opportunities for colleagues, postdocs and students to partner with our research teams. The purpose of this newsletter is to profile the breadth of research at PNNL - and to highlight opportunities for collaboration. In this way, Currents is our way of starting conversations. Please email us at if you have any questions or are interested in learning more about PNNL's science and technology. Thank you.

Geologic carbon dioxide sequestration inhibits microbial growth

Collaborators: The Ohio State University

A recent study published in Frontiers in Microbiology revealed how geologic carbon dioxide injections affect sulfate-reducing bacteria that catalyze a key biogeochemical process in the deep subsurface. Ultimately, these findings offer an insight into the effects of carbon dioxide sequestration on indigenous microbial populations, and could lead to new strategies for improving the success of carbon dioxide sequestration and help to mitigate climate change.

Novel electrode coating for improved batteries

Collaborators: University of Pittsburgh; University of Colorado; National Renewable Energy Laboratory; FEI Company

New research published in ACS Nano will help scientists create longer-lasting, higher-capacity lithium rechargeable batteries. Researchers showed how a coating that makes high capacity silicon electrodes more durable could lead to a replacement for lower-capacity graphite electrodes. Read more.

New method to target marine cloud features

Postdoctoral researcher Matus Martini's first paper at PNNL was selected for a recent cover of the Journal of Geophysical Research: Atmospheres. The research developed a new automated method to target specific clouds over the oceans for climate modeling. Marine clouds are important for modulating the climate, because they affect the amount of sunlight absorbed by the ocean. Read more.

Enzyme insights may help biofuel production

Collaborators: Indiana University; University of Arizona; Florida State University; Monsanto Company

A new study reveals novel insights into enzymes important for genome stability and gene regulation related to plant development. This may one day enhance sustainable agriculture and biofuel production. The research was published in Cell Reports. Read more.

Gaining fundamental insights into polyoxometalate anions

While precisely controlling the charge state of molecules resting on a surface may seem esoteric, it is the key to improving the efficiency of chemical reactions and creating memory storage devices using nanoparticles. New research provides fundamental insights into the behavior of polyoxometalate anions and how to control it. Published in The Journal of Physical Chemistry C, the results may help in the design of new catalysts and portable electronics with greater charge capacity. Read more.

Soot study could improve climate models

Collaborators: Stanford University; University of Toronto; University of Dayton Research Institute

Research is providing a better understanding of the chemical nature of soot particles. New findings, detailed in Physical Chemistry Chemical Physics, could lead to improved climate model representations of soot's chemical and physical properties, greater insight into the role of soot in cloud formation, and cleaner aviation engines through more accurate soot models.
