TC-PRISMA evaluates concurrent nucleation, growth and coarsening, and incorporates key models and algorithms from QuesTek’s PrecipiCalc precipitation simulation software. Charlie Kuehmann, QuesTek’s President and CEO, commented, “The launch of TC-PRISMA software is very timely given President Obama’s recent establishment of the Materials Genome Initiative. TC-PRISMA is an important new tool for materials design engineers to computationally design materials.
China’s cement growth slows in November 2011, but flat glass output accelerates
China’s building materials showed different momentum of growth in November 2011, with a slowing cement output growth and a speeding plate glass, according to latest statistics from the country’s top economic planner. Cement output growth in November 2011 stood at 11.2 percent year-on-year, 6.1 percentage points lower than previous year, while plate glass production expansion reached 7.1 percent year-on-year, quickening by by 0.5 percentage points from previous year. Still, China’s cement output reached 1.89 trillion tonnes in the first 11 months of last year, an increase 17.2 percent year-on-year, 1.6 percentage points faster than previous year. The output of flat glass, a sector fraught with overcapacity and duplicated construction problems, rose 17 percent year-on-year to 6.82 trillion weight boxes in the January-November period of last year.
AGA cookers go greener with aerogel ‘Cool Covers’
Designed as a simple retrofit option for the AGA Classic, Cool Covers are aerogel insulated and magnetically attach to the underside of hob lids to obstruct heat transfer from the hob plates to the lids. Not only do Cool Covers reduce total cooker energy consumption, but they also cut CO2 emissions by up to 0.55 tons/year, decrease kitchen temperatures in summer, and act as self-cleaning spatter guards to keep the lid liners clean.
Partnerships are key to the success of companies in printed, organic, and flexible electronics. To see which companies are best candidates for alliances, Lux Research applied the Lux Innovation Grid to rate technology developers in displays, organic photovoltaics, smart packaging, transparent conductive films and thin-film batteries, in a new report. ”Successful projects require bringing together companies to support the three key areas of expertise: materials, equipment and devices,” said Jonathan Melnick, Lux Research analyst and the lead author of the report. “Few, if any, companies have best-in-class capabilities in all of these areas, so picking partners with care is an essential component of a successful strategy.”

Oxygen (red spheres) migrates from one vacancy to another inside the scandia-doped cubic zirconia. In this new SOFC material, the oxygen must brush past cations (marked by the letter E).
The DOE Pulse reported that, using specialized cubic zirconia, scientists from Nanjing Normal University in China and Pacific Northwest National Lab created a membrane that could drop the temperature inside solid oxide fuel cells. Lowering the temperature means these cells could be built from less expensive materials.
Currently, the temperature inside SOFCs is about 1,000°C. With this much heat, the cells must be constructed using very durable and expensive ceramics. The team, led by NNU’s ed by Zhongging Yu, says its new scandia-doped cubic zirconia can work at temperatures as low as 650°C.
Using oxygen-plasma-assisted molecular beam epitaxy, the researchers grew scandia-stabilized zirconia films on sapphire substrates. The films were examined using x-ray diffraction, electron spectroscopy and microscopy.
The team used theoretical calculations and computational models to determined that nanoscale, nanosecond interactions occurring in the scandia-doped cubic film conducted oxygen faster than the yttrium doping in current electrolytes.
They say their work provides a fundamental understanding of how ions move in scandia-doped zirconia, and shows the material is very stable. “Our integrated approach takes the science to the next level,” says Theva Thevuthasan, who worked on the project and currently oversees the deposition and microfabrication capability at Environmental Molecular Science Lab at PNNL.
According to a PNNL news release, the group also has high hopes for another SOFC material made from nanolayers of zirconia and ceria.
The Energy Innovation track at the Ceramic Leadership Summit June 21-22 in Baltimore, Md., will highlight advances and challenges facing the the future of energy creation, harvesting and storage. Nuclear energy, solid-oxide fuel cells and sodium metal halide batteries are just a sample of the topics to be covered by industry leaders.
Here are the abstracts for the planned presentations in this track -
Enabling a nuclear renaissance: ‘Better, faster, cheaper’ using advanced ceramics (John Marra, associate lab director, Savannah River National Lab)
The nuclear industry is at the eye of a perfect storm with fuel oil and natural gas prices near record highs, worldwide energy demands increasing at an alarming rate, and increased concerns about greenhouse gas emissions that have caused many to look negatively at long-term use of fossil fuels. This convergence of factors has led to a growing interest in revitalization of the nuclear power industry within the United States and across the globe. This session will discuss the critical role that ceramic materials play throughout the entire fuel cycle and the critical role of materials advancements in the nuclear renaissance.
Next steps for fuel cells (Two presentations: Robert Rose, Robert Rose, senior advisor, US Fuel Cell Council; Claus Peter Kluge, R&S manager, CeramTec AG)
(Rose) Fuel cells are entering early markets in consumer products, generators of electricity; combined heat and power systems, industrial vehicles, and much more. Solid oxide systems are being developed for many of these markets, and the DOE envisions SOFC systems as simplifying and reducing the cost of carbon sequestration from coal. Rose will discuss the fuel cell vision, and the steps needed to make the vision a reality.
(Kluge) There was and is a fascination for converting energy only in two main portions: heat and electricity. There is no need for moving parts like pistons which will generate additional parasitic losses like friction and noise. Where we come from defines the state-of-the-art. Future technological, social and environmental aspects will define the way to go. The goal is to decrease costs and complexity in the customers’ cognition and to morph the specialty into a high volume standard product. The challenges are material development and processing to get well-defined, efficient and reliable products.
An industry perspective: Development and application of ceramic materials for efficient and clean power generation (William Treadway, group leader for ceramics and deputy department leader for the Physical Sciences Department, United Technologies Research Center; Ellen Sun, principal research scientist, UTRC)
UTRC is the central research organization for United Technologies Corporation - a world leader in the development and integration of energy efficient and clean power generation systems. The presentation will share UTRC’s experience in materials development, component testing, and system or sub-system demonstration and discuss material needs for near-term efficient and low emission power systems.
Materials for advanced sodium metal halide batteries (Mohamed Rahmane, senior engineer/project leader, GE Global Research)
The world needs large-scale energy storage devices and systems that are safe, reliable and economical. There are currently very few economically viable and technically feasible storage solutions that are dispatchable and meet the stringent cost and reliability demands. High-energy-density sodium metal halide battery technology is emerging as one of the key solutions, and GE is addressing the technology challenges and taking it to the manufacturing and commercial stages. This presentation will discuss the critical role that materials, particularly ceramics, play in the performance and life of sodium metal halide batteries.

According to a new report from Lux Research, the market for batteries, supercapacitors and fuel cells targeting transportation and smart grid applications will more than double from $21.4 billion in 2010 to $44.4 billion in 2015.
ACerS’ upcoming Ceramic Leadership Summit will introduce key figures in the energy storage technology sector that will expound on how to harness that $44 billion. The Energy Innovations track on Tuesday, June 10, will include talks on enabling a nuclear renaissance, current and future prospects of fuel cells, the strategic field of energy conversion. A representative from United Technologies will also present an industry perspective on energy storage, SOFCs and energy and emission reduction in gas turbines.
The Lux report, titled “Emerging Technologies Power a $44 Billion Opportunity for Transportation and Grid,” analyzes the prospects for several technologies, including batteries, supercapacitors, fuel cells in transportation and storage, distributed generation and transmission and distribution technologies on the power grid.
Some key findings are listed in the summary:

Ann Arbor-based Adaptive Materials Inc, a specialist in making microtubular solid oxide fuel cells, announced yesterday that it has won $3 million in new funding through Michigan’s Centers of Energy Excellence Program.
AMI, until now, has focused most of its efforts on military uses for its SOFCs, such as soldier-worn units, power sources for unmanned vehicles and field uses. The company has both 50- and 250-watt SOFCs that can be fuel with off-the-shelf propane and butane canisters.
While AMI’s business plan has always mentioned applications in the recreational vehicles, boating and medical devices markets, the reality is that it has been easier for military customers to justify the relatively high costs of these portable power devices.
However, a press release from AMI notes that, “The company will use the funding to support the commercialization of its fuel cells within the consumer leisure market.”
AMI may be on to something. It has always struck me that there is some pretty strong logic behind developing small SOFC products whose form factor incorporates safe, cheap and easy to find fuel cartridges. Generations of campers, for example, have grown up using portable stoves and lamps that use these small gas canisters.
Michelle Crumm, AMI chief business officer, says, “Funding from COEE provides the extra boost we need to break into the consumer market and deliver a truly game-changing technology. . . By focusing our technology on readily-available fuels, Adaptive Materials solved a problem associated with fuel cells: Consumers could certainly find need for a fuel cell, but no fuel to actually sustain the unit.”
Presumably, AMI will use the funds to continue to drive down the production costs of making their SOFCs. The company uses a unique co-extrusion method to form its microtubular SOFCs. Earlier this year, in the pages of ACerS’ International Journal of Applied Ceramic Technology, the University of Birmingham’s (U.K.) Kevin Kendall praised recent developments in microtubular SOFC science and applications:
Significant progress is being made in the development of microtubular SOFCs. Since its invention in the early 1990s, information about its benefits has been disseminated, leading to the start-up of several companies interested in applications from laptop power supplies to combined heat and power to transport and APUs.
Plastic extrusion is the main method for producing microtubular cells. This is an economic process, which can lead to high-quality ceramics with good strength and Weibull modulus. Co-extrusion is also a promising possibility that could produce one-step processing of cells.
A key benefit of microtubular SOFC is the increased power density, inversely proportional to diameter. Power densities of 1 kW/L are possible but the number of cell connections rises with the square of power density and could become the limiting factor. Thermal shock resistance of microtubes is many orders of magnitude better than that of planar SOFCs. Ramp rates of 8000 K/min are possible.
Aaron Crumm, Adaptive Materials’ chief visionary officer and co-founder, along with John W. Halloran, published an excellent paper in ACerS’ Journal of the American Ceramic Society back in 1998 about innovative methods to micromanufacture complex ceramic–metal structures:
These structures are fabricated by multiple pass co-extrusion of a feedrod comprised of several powder-filled thermoplastic compounds. The compounds contain either ceramic, metal or fugitive powders. To illustrate the capabilities of microfabrication, a demonstration part containing lead manganese niobate-lead titanate ceramic and silver palladium was fabricated. The final part was microconfigured, with a fenestrated structure containing 3110 repeat units per square centimeter. The repeat unit feature sizes were 15 and 5 µm for the ceramic and electrode, respectively. Microfabrication by co-extrusion is proposed as a fabrication technique for the production of smart structures and materials.
