Ceramic material grabs pollutants

Article Abstract:

Researchers at Pacific Northwest National Laboratory have developed a newceramic material called Self-Assembled Monolayers on Mesoporous Supports (SAMMS), which can bind with contaminant chemicals including radionuclides. SAMMS can also be used in water, nonaqeous solutions or gas-phase waste streams. The Dept of Energy is studying the potential of SAMMS in soil and water cleanup activities, where mercury is prevalent, and in the elimination of mercury from radioactive and hazardous wastes.

New ceramics avoid distortion

Article Abstract:

A new method for creating ceramic parts that will not shrink nor change shape has been developed by researchers at Ohio State University. The ceramic parts have the potential to be used in fuel cells or in gas and temperature sensors. The process uses two types of metals - one that expands when oxidized and another that contracts. Mixing the proper amounts of both types of metals brings no net volume change in the mixture during firing.

Robotics creates precise ceramics

Article Abstract:

A robocasting process used in fabricating ceramics was developed by engineers at the US Department of Energy's Sandia National Laboratories in Albuquerque, NM. The new process, which does not neet neither molds nor machining, uses robotics for computer-controlled deposition of a ceramic slurry through a syringe. The slurry is a mixture of water, trace amounts of chemical modifiers and ceramic powder.
