Summary
Description
<p>The project involved the development and testing of a new alumina-silicate based multi-purpose, cost-effective, &lsquo;green&rsquo; cementitious binder (geopolymer) capable of acting as a high performance refractory material with both a low ablation rate and a high early mechanical strength. This work was built upon previous research undertaken by the research team in the areas of geopolymer binders. Full scale and laboratory controlled tests were performed to compare geopolymer performance to currently available commercial products (e.g. Sentinel, Greencast). Geopolymer&rsquo;s thermal shock resistance properties were tested on eleven different fly ash stockpiles specimens from around the world. The geopolymer specimens were subjected to ASTM C-1100 (Standard Test Method for Ribbon Thermal Shock Testing of Refractory Materials). Samples were subjected to incremental 5-5-5-15-30 second flame exposure durations and to a 15 or 30 accumulated exposure, depending on the sample performance (e.g., if the plume became detached). Field test durations were limited to prevent excessive erosion of the test panels and subsequent plume detachment. Laboratory testing also demonstrated that geopolymer could withstand thermal shock and exposure to flame. Additionally, a computational model was created to determine the optimal chemical ratios for geopolymer to be exposed to elevated temperatures. Additionally, due to their excellent adhesion to pre-existing surfaces geopolymer binders were proven to be good candidates for use in repair of existing structures upon which they were applied and retrofitted; this was demonstrated and observed via tests conducted on repaired tested panels. Overall, the demonstration testing program revealed that the geopolymer products had equal or superior performance compared to commercial refractories currently used by NASA.</p>

The 2011 Toxics Release Inventory (TRI) dataset contains the most current TRI data available and reflects toxic chemical releases and pollution prevention activities that occurred at TRI facilities during the 2011 calendar year. You can use this dataset to find out what TRI-covered toxic chemicals are being produced and used at industrial facilities in your local area and how they are being managed. Please note that this dataset will change as the TRI Program continues to process TRI submissions. The TRI Program provides this dataset annually in late July to give the public an opportunity to see the most recent TRI information prior to the publication of the TRI National Analysis report in December.

NLRB C-Case (Unfair Labor Practice) data from CATS (Case Activity Tracking System) for the period of 01/01/1999 through 09/30/2011. Please be aware that from April 2011 through September 9, 2011, the NLRB implemented a new case management system (NxGen) that replaced CATS. This was an ongoing process, and each month, from April through September, additional regions migrated to NxGen, with the data for those regions being retained solely in NxGen. Accordingly, for cases that did not close before a region migrated to NxGen, any information regarding subsequent actions or dispositions that occurred after the region migrated to NxGen was not captured in CATS. Thus, this is the most complete information available from CATS. This supersedes any previous XML data publication by the NLRB on Data.Gov, as significant data review and cleanup was performed in CATS prior to the migration to NxGen. This also represents the final posting of the bulk-data (aka "Data Dump") from CATS. There are some known closing-date errors in this data, reflecting data-entry mistakes within CATS that have been identified and corrected within NxGen. This data has not been corrected within CATS since CATS is no longer the system of record for this Agency. Therefore, if any case shows a closing date beyond 09/30/2011, you can find the corrected closing date on http://www.nlrb.gov, under "Cases & Decisions," "Case Search."

The Center for Program Analysis maintains information related to RE-Powering America's Land Initiative, which demonstrates the potential that contaminated lands, landfills, and mine sites provide for developing renewable energy in the United States. The Data Asset comprises maps and shape files that show completed installations as well as renewable energy potential. It also includes a feasibility study data set that was completed in cooperation with DOE National Renewable Energy Laboratory (NREL) to pair EPA expertise on contaminated sites with the renewable energy expertise of NREL. Data Sets that demonstrate renewable energy potential exist for each EPA region. These Data Sets are not all-inclusive and do not identify best sites, and additional research and site-specific analysis is needed to verify viability for renewable energy potential at each site.

The ARES J-2X requires a large nozzle extension. Currently, a metallic nozzle extension is being considered with carbon-carbon composite as a backup. In Phase 1, Plasma Processes Inc. (PPI), with the support from subcontractor ATK Launch Systems, fabricated, coated and test fired Haynes 230 and domestically produced 2-D carbon-carbon nozzle extensions. The test results show coated carbon-carbon intact and Haynes 230 in need of film cooling and emissivity and, or thermal barrier coatings. Oxide emissivity coating reduced the Haynes 230 wall temperature by 500F. In Phase 2, the primary goal will be to develop the optimum thermal solution for a metallic J2X nozzle extension. Working with Pratt & Whitney Rocketdyne, high emissivity and thermal barrier solutions will be demonstrated on successively larger components until full size capability is demonstrated. A secondary goal is to continue the demonstration of domestically produced 2-D C/C composite nozzle extension materials and oxygen protective liners for use on liquid rocket engines. The team of Plasma Processes, Inc., Pratt & Whitney Rocketdyne and ATK Launch Systems offers the state of the art skill set that is uniquely suited to the Phase 2 program.
