Vitrification process turns radioactive waste into durable glass for safe disposal

By Faye Oney / June 8, 2018

Researchers have successfully converted radioactive waste into glass through vitrification at the Hanford Nuclear Site. The test is part of an overall plan to send low-activity waste directly to the vitrification facility via Direct Feed Low-Activity Waste system.

New explanation for electrical conductivity at oxide-oxide interface

By Eileen De Guire / November 16, 2011

A cross-sectional scanning transmission electron micrograph of the interface between polar lanthanum chromium oxide and nonpolar strontium titanium oxide. Although the interface appears to be atomically abrupt, detailed spectroscopic measurements show that cation mixing occurs in the interfacial region. Credit: PNNL. Electrical conductivity is a pretty simple concept to understand: electrons move. Like water that…

Video of the Week: Making better batteries with metal oxide & graphene composites at PNNL

By / March 9, 2011

This video explains one route researchers at Pacific Northwest National Lab and Princeton are taking to create better materials for batteries: materials that assemble on their own into durable nanocomposites. Details are also provided about surfactants used in conjunction with tin oxide and functionalized graphene. The video features interviews with PNNL researcher Jun Liu and Princeton’s…

Video of the week: Lithium ions cause nanowires to writhe, swell and twist

By / December 10, 2010

[flash https://ceramics.org/ceramictechtoday/wp-content/video/lithium_ion_nanowire.flv mode=1 f={image=/ceramictechtoday/wp-content/video/lithium_ion_nanowire.jpg}] Some lithium ion batteries are plagued with, well, physical problems. Some of the mechanical effects are manifest as batteries that get very hot. Others swell, especially when overcharged, as has been noted by many authors (see here, for example). But seldom has the physical effects of lithium ion movement been demonstrated…

PNNL researchers publish update on pancake-like sodium beta battery concepts

By / October 16, 2010

Over six months ago, Ann reported that PNNL researchers were starting to see some success in re-engineering the form of sodium beta batteries (NBB) from a cylinder-type of construction to a flat disc in which the components are stacked. Initial investigation showed that by changing the form, the performance could be improved by 30% and…
