Follow up: Chalcogenide phase-change memory materials for high-speed, low-power data storage

By Eileen De Guire / June 9, 2011

I’ve received some follow-up information from Gang Chen, whose work on phase-change memory chalcogenide materials I wrote about earlier this week. He provided some numbers that illustrate the potential for very impressive reductions in power consumption for nonvolatile data storage based on PCMMs. Chen notes that the quoted 30-50% reduction in power consumption from lowering…

Video of the week: Richard Bradt’s “A fracture mechanics view of the practical strength of glass”

By / June 8, 2011

[flash https://ceramics.org/ceramictechtoday/wp-content/video/bradt_strength_of_glass.flv mode=1 f={image=/ceramictechtoday/wp-content/video/bradt_strength_of_glass.jpg}] Organizers of the Glass & Optical Materials Division’s 2011 meeting invited veteran materials engineer Richard C. Bradt to address the topic of glass strength. Bradt, the Alton N. Scott Professor Emeritus, Department of Metallurgical and Materials Engineering, University of Alabama, covers a lot of territory in a presentation he entitled, “A fracture mechanics view…

New solar materials opportunities: glass frontsheets, anti-reflective coatings

By / June 3, 2011

Credit: SolarWorld. A lot of attention is paid to making photovoltaic modules more cost-effective by reducing the costs associated with the active materials, and, indeed silicon prices seem to be dropping (with estimates of somewhere between 5 and 7 percent for the first quarter of 2011, after similar drops in 4Q 2010) despite double-digit growth…

Video of the week: Ash, sand-resistant thermal barrier coatings and novel test rig

By / June 2, 2011

[flash https://ceramics.org/ceramictechtoday/wp-content/video/osu_turbine_coatings.flv mode=1 f={image=/ceramictechtoday/wp-content/video/osu_turbine_coatings.jpg}] Apropos to the latest round of ash clouds spewing from the EyjafjallajökullI volcano, plus indications that some utilities are going to be building new high-temperature fast-cycle gas turbines for peak electrical power generation, we offer this video that expands on a story I first wrote about in April. It regards an…

Energy Frontier Research Centers to showcase work on ‘grand challenges’

By / May 24, 2011

Credit: DOE The next few days should be fun for materials scientists and engineers. Tomorrow (May 25) begins the start of a three-day meeting where participants in the DOE’s 46 Energy Frontier Research Centers will begin the initial reporting-out (at least to the public) about what kind progress they have been able to make. There…
