The resulting micro-SOFC electrolyte membrane showed a hexagonal-pyramid array nanostructure and achieved a power density of 1.34 W/cm(2) at 500 C. A fabricated nanotubular SOFC theoretically attains a 20-fold increase in the effective surface, while projections indicate the possibility of achieving up to 40-fold. Engineering artificial tissue scaffolds with a similar organization to that of the natural tissue is a key element to the successful recapitulation of function. In: Micro Power Sources. Chang, Y.

Prior to joining QuantumScape, he was a Research Associate at Stanford University from June 2008 to January 2011. Further extension of these techniques to create a micro-vascular network within or between layers is possible.

By scanning the Li intercalation potential from high to low, we have gained control of multiple important material properties in a continuous manner, including tuning the oxidation state of Mo, the transition of semiconducting 2H to metallic 1T phase, and expanding the van der Waals gap until exfoliation. Lithium-ion batteries are at the heart of the next transportation revolution, but in the technologys current form, they fall short of meeting the needs of drivers in key areas like battery life, charging speed and cost. We used atomic force microscopy-based force spectroscopy to record an increase in the cytoskeletal tension after treatment with electric fields. QuantumScape has developed some impressive technology but sustaining the current valuation could prove a challenge too far. This result suggests the ability to significantly reduce Pt loading, thereby reducing the cost, and furthermore, can be easily applied to high performance fuel cells with complex 3-D structures.
