SLAC Archives and History Office (AHO) backlog of unprocessed material is over 3,000 cubic feet and growing. Because much of this material was directly transferred to off-site storage, the provenance and contents are a mystery. The costs of off-site storage, lack of knowledge of the contents, and the impending federal regulations in 2009 concerning storage facilities all suggest the need for a long-term plan for the backlog. AHO presents these options to SLAC management: (1) Continue with the status quo, adding new accessions to OffSite Records Management, LLC (hereinafter referred to as OffSite) storage; (2) Pull the backlog back a segment at a time for box-level processing, determine what is in each box, get rid of extraneous material, and return what is left to OffSite storage; (3) Gradually retrieve the backlog for thorough, folder-level processing and then transfer to the Federal Records Center in San Bruno (hereinafter referred to as FRC) or the Archives side of the operations at the National Archives and Records Administration in San Bruno (hereinafter referred to as NARA); and (4) Gradually retrieve the backlog for a combination of box-level processing with return to OffSite storage and thorough folder-level processing with transfer to FRC or NARA.

Solid oxide fuel cells (SOFC) hold great promise for clean power generation. However, high temperature stability and long term durability of the SOFC components have presented serious problems in SOFC technological advancement and commercialization. The seals of the fuel cells are the most challenging area to address. A high temperature gas seal is highly needed which is durable against cracking and gas leakage during thermal cycling and extended operation. This project investigates a novel composite seal by integrating 3D printed shape memory alloy (SMA) wires into a glass matrix. The SMA we use is TiNiHf and the glass matrix we use is SrO-La{sub 2}O{sub 3}-Al{sub 2}O{sub 3}-B{sub 2}O{sub 3}-SiO{sub 2} (SLABS). Dilatometry shows to be an extremely useful tool in providing the CTEs. It pinpoints regions of different CTEs under simulated SOFC thermal cycles for the same glass. For the studied SLABS glass system, the region with the greatest CTE mismatch between the glass seal and the adjacent components is 40-500 C, the typical heating and cooling regions for SOFCs. Even for low temperature SOFC development, this region is still present and needs to be addressed. We have demonstrated that the proposed SLABS glass has great potential in mitigating the …

This report is part of the Web-at-Risk project. Several enhancement ideas for future releases of the Web Archiving Service (WAS) have been identified. In order to refine and prioritize these ideas as well as elicit new enhancement ideas, 16 project curators participated in an online exercise between November 27 and December 16, 2007. The exercise employed a Delphi technique that consisted of a series of three online questionnaires, each available for a five or six day period. This report describes the exercise and reports the results.
