3D nanostructures

By Chemical Engineering |

By combining a high-resolution scanning electron microscope and an ion-beam microscope into a single device, researchers at the Max Plank Institute for Iron Research (Düsseldorf, Germany; edlinks.chemengonline.com/5828-545) are able to “see” the inner structure of nanomaterials, biological matter, and high-performance steels in three dimensions.The technique is faster than x-ray (or electron- or neutron-beam) scattering, and has two-orders of magnitude better lateral resolution. The device has been used to study chromium-doped iron-aluminum intermetallic alloys, which, because of their high resistance to oxidation and sulfidation, could be used in new high-temperature gas turbines.

 

Ant power?

Tekion, Inc. (Champaign, Ill.; edlinks.chemengonline.com/5828-546) is collaborating with BASF AG (Ludwigfshafen, Germany) — the world’s largest producer of formic acid — to develop formic acid formulations to be used as fuel for Tekion’s fuel-cell technology. Tekion has an exclusive license from the University of Illinois, for a proprietary hybrid system, tradenamed Formira Power Pack, which uses a micro fuel cell to recharge a battery, allowing extended operation of mobile electronics devices. The power packs are refueled by exchanging a cartridge containing formic acid.

The partnership is expected to further the commercialization of the Formira Power Pack. The hybrid system is suitable for electronic devices in the power range up to 50 W and the energy range up to 100 W-h; this is the range required by industrial handheld computers, satellite-communication devices, notebook PCs and other mobile products, says BASF.
