Mechanical strength standards set for honeycomb ceramics

By / September 20, 2008

ASTM International has issued a new global standard to address the use of honeycomb ceramics in automotive catalytic converters, diesel particulate filters and combustion burner plates. The standard, ASTM C1674, Test Method for Flexural Strength of Advanced Ceramics with Engineered Porosity (Honeycomb Cellular Channels) at Ambient Temperatures, has been developed by group’s Subcommittee C28.04 on Applications,…

Nanoceramic particles: The new Slick 50?

By / September 19, 2008

Is it really true that everything “new” in engines is old? Some days it seems that way. Today we received word of a nanoceramic oil additive for combustion engines (and other mechanical-friction applications) from CerMetLab that offers itself as a way to reduce metal-on-metal friction and improve fuel economy and efficiency by 15 percent. Does…

Community Bulletin Board installed

By / September 17, 2008

We’ve installed a new community/forum tool that has replaced our first “Community Bulletin Board.” This tool is called the “Community Forum” and a link can be found here or at the top of the blog page. This is a page for readers to post requests for help, questions, networking opportunities, etc. If you have a…

Video of the week: New approach to solar concentrators

By / September 17, 2008

Researchers at MIT (see post below) have developed a novel way to concentrate sunlight for solar cells that doesn’t involve mirrors and tracking mechanisms. They use a system of glass and coatings to guide and collect light at the edges of the pane where solar cells can be positioned. Team leader Marco Baldo explains their…

Double-duty windows harvest solar energy

By / September 17, 2008

What if your house’s windows offered double-duty performance by not only letting in sunlight but also harvesting its energy to efficiently and cost-effectively power your home? That’s the concept behind the organic solar concentrator, a new kind of solar powering device, recently developed by MIT researchers and reported on in Science. “Light is collected over a large area…

NanoDynamics gets DOE boost for 400-watt SOFC

By / September 16, 2008

Buffalo, New York’s NanoDynamics Energy is at the receiving end of a nice DOE grant to continue development a 400-watt solid oxide fuel cell fuel by hydrogen, methane gas and related biogases. The $2.4 million contract allows NanoDynamics to scale-up their technologies from previous 20-watt+ prototypes SOFCs running on biogas, and develop efficient manufacturing techniques.

ORNL confirms Spaniards’ ionic conductivity ‘superhighway’ that may boost SOFCs

By / September 15, 2008

Investigators at the Oak Ridge National Lab have confirmed startling characteristics in a solid electrolyte material we reported on several weeks ago, one that should allow solid oxide fuel cells to operate at temperatures hundreds of degrees lower than what is currently possible and boost the practicality of solid-oxide fuel cells. To recap, a research…

Iranian research getting noticed

By / September 13, 2008

Iran isn’t necessarily known for being a leader in ceramic and related material science, but some recent announcements suggest they shouldn’t be ignored either. For example, one group has successfully produced a sulfonic acid nano-catalyst with the ability to be recycled more than 20 times. They envision this material to be a replacement in industrial…

Advance makes thermoelectrics twice as efficient

By / September 12, 2008

Ohio State University researchers say they have invented a new material that “will make cars even more efficient by converting heat wasted through engine exhaust into electricity” and with “twice the energy efficiency” of any thermoelectric material currently on the market. Lead researcher Joseph Heremans, an OSU professor of mechanical engineering and physics, reports on the new…

Boron nitride may provide ‘clear’ solar panels

By / September 10, 2008

Work at Japan’s National Institute of Materials Science may allow solar cells to be built into you house and car windows, windshield and even your sunglasses. The NIMS group, led by Dr. Shojiro Komatsu, has been interested in BN cell because it would be transparent to the visible light spectrum. Researchers claims to have already…
