Existing techniques to detect pertechnetate in the environment have drawbacks. PNNL’s redox sensor technology uses a gold probe to accurately and efficiently measure low levels of pertechnetate—and possibly other contaminants—in groundwater
Researchers adding water to the surface of alumina measured some surprising results that raise important questions regarding the fundamental reactions that govern chemical transformations of aluminum oxides and hydroxides.
Scientists at the Interfacial Dynamics in Radioactive Environments and Materials (IDREAM) sort out which compounds are present and their concentrations, providing an important new tool with broad applicability.
The vast reservoir of carbon stored beneath our feet is entering Earth's atmosphere at an increasing rate, according to a new study in the journal Nature.
For the first time, researchers have created a gram of yellowcake — a powdered form of uranium used to produce fuel for nuclear power production — using modified acrylic fibers to extract it from seawater.
A mix of factors is contributing to an increasing mortality rate of trees in the moist tropics, where trees are dying at about twice the rate they were 35 years ago.
Tiny particles fuel powerful storms and influence weather much more than has been appreciated, according to a study by PNNL scientists and colleagues in the journal Science.
A new research approach to geoengineering could potentially be used to limit Earth's warming to a specific target while reducing some of the risks and concerns identified in past studies.
PNNL scientist Janet Jansson led scores of scientists who published in the journal Nature the most extensive snapshot ever of the vast microbial life on Earth.
Six energy technologies that do everything from protect fish to monitor the health of flow batteries are getting a boost at PNNL with support from DOE's Technology Commercialization Fund.
