Ceramics at the heart of advances in hydrogen production

By Jim Destefani / May 25, 2013

Berkeley researchers’ nanowire “artificial forest” for photosynthetic hydrogen production consists of silicon “trunks” and titanium oxide “leaves.” Credit: Lawrence Berkeley National Laboratory. Hydrogen is considered by many to be the Holy Grail of clean energy, but a major hurdle to moving toward the hydrogen economy is producing enough of the gas to make a significant…

Editor’s note—The generation that grew up reading the Harry Potter septology, grew up imagining things like invisibility cloaks as reality. The oldest of those young readers are now graduate school age and making invisibility cloaks for real.…

Topological insulator materials: From quantum mechanics to computers

By Eileen De Guire / May 20, 2012

Electrons on the surface of a topological insulator can flow with little resistance. Their spin and direction are intimately related; the direction of the electron determines its spin and in turn is determined by it. Credit: LBNL. Last week several press releases came out about new work on topological insulators. A topological insulator—more accurately, a…

Check ’em out: Warning on fracture of the alumina-bearing couple delta ceramic liner in hip implants Although the fracture rate of third-generation alumina-bearing couples is low, we believe that it may not be possible to eliminate the actual risk of alumina head fracture. Patients should be informed about the potential for this complication before receiving…

Duke, NETL study CO2 storage impact: Leakage must be reckoned with

By / November 30, 2010

Duke University, in collaboration with the DOE, just completed a study on carbon storage and the impacts of CO2 injection into different geologic formations. The findings were published in the Oct. 26, 2010 edition of Environmental Science & Technology. The report, “Potential Impacts of Leakage from Deep CO2 Geosequestration on Overlying Freshwater Aquifers,” also presented…

Video of the week – Two approaches to cloaking

By / January 21, 2009

[flash /ceramictechtoday/wp-content/video/cloaking_concepts.flv mode=1 f={image=/ceramictechtoday/wp-content/video/cloaking_concepts.jpg}]   Several research teams are actively pursuing cloaking/invisibility concepts. One of the prominent groups is at Duke University and the other is at University of California, Berkeley. The Berkeley team uses a crafted nano-prism of metamaterial atoms that has a negative refractive index for light of near-infrared wavelengths. The Duke team…

Who cloaked my cheese?

By / January 18, 2009

Back when “Ceramic Tech Weekly” was still just a newsletter (waaay back in mid-2008), I wrote several stories (see here and here) about the emerging technologies related to what is often referred to as “invisibility,” a.k.a., “cloaking” (hello Trekkies). Of course, there is a certain tendency to treat this as something of a novelty. But…
