“…͓DOI: 10.1063/1.2245216͔ Carbon aerogels are a class of nanoporous aerogel solids with high porosity and low density. [1][2][3][4][5][6][7][8][9] Because of their high conductivity, carbon aerogels are often used electrochemically 10,11 and as supercapacitors. 10,12 The desire to produce stable, high surface area catalytic electrodes has generated significant interest in incorporating metal catalytic sites onto the inner surfaces of such materials.…”

In this study, the authors demonstrate the ability to apply precise, conformal W coatings onto all surfaces of nanoporous carbon aerogels using atomic layer deposition (ALD). The resulting material has a filamentous structure in which the W completely encapsulates the carbon aerogel strands. The material mass increases nonlinearly with W coating, achieving a tenfold increase following ten ALD cycles. The aerogel surface area increases by nearly a factor of 2 after ten W ALD cycles. This conformal metal coating of extremely high aspect ratio nanoporous materials by ALD represents a unique route to forming metal functionalized high surface area materials.

“…Carbon aerogels are typically prepared through the sol-gel polymerization of resorcinol with formaldehyde in aqueous solution to produce organic gels that are then supercritically dried and subsequently pyrolyzed in an inert atmosphere (Berthon-Fabry et al 2004;Brandt, and Fricke 2004;Pekala 1989;Pérez-Caballero et al 2008;Wiener et al 2004). Several possibilities exist for reducing the cost of producing carbon aerogels, including several new synthetic routes for preparation of organic aerogels.…”

Processes for Removal and Immobilization of 14C, 129I, and 85Kr

There are methods that are current candidates for the removal and immobilization of 14 C, 129 I, and 85 Kr. These methods have been outlined by Gombert (Gombert II 2007) and are not covered in this white paper. The methods covered here are those suggested by the current state-of-the-art science that show promise for the removal or immobilization of these isotopes from an advanced fuel cycle reprocessing plant. For the purposes of this white paper, all processes suggested by Pacific Northwest National Laboratory scientists are considered. The number of these processes to be actively investigated is reduced through a preliminary grading so that a small research project can be carried out to obtain a data set with which further decisions about these technologies can be made. Some of the technologies considered here are only immobilization methods, while some are both removal and immobilization methods.
