Identifying and quantifying specific alpha- and beta-emitting radionuclides in liquid solutions can be challenging and time consuming – typically taking from days to weeks to get results back from an analytical laboratory. But, when an industrial process-scale plant requires that an accurate, reliable analysis be completed in near real-time from samples retrieved directly from the process line, the challenge could be overwhelming. However, scientists at Pacific Northwest National Laboratory have assembled a robust, fully automated prototype process monitor to meet demanding production needs.
The device developed by PNNL scientists provides microwave-assisted sample pretreatment, flexible chemical separations capabilities, sensitive radiochemical detection, calibration and data analysis. PNNL presenter Matthew J. O’Hara said, "This is the most extreme example of automation ever demonstrated by our team."
The prototype system was originally created to perform rapid radiochemical analysis of technetium-99 in nuclear waste destined for vitrification at the Hanford Site’s Waste Treatment Plant in Washington state. Samples can be adjusted, separated and analyzed in less than 15 minutes to provide feedback on process performance.
While developed for specific radionuclides in high-level nuclear waste process streams, the analyzer is capable of being adapted for use on a wide range of applications requiring an integrated system that performs sample preparation, column separations, on-line detection and data analysis conducted rapidly and autonomously.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
