A select number of scientific communities have been quite successful in evolving the culture within their community to encourage publishing and to provide resources for re-using well-documented data. These data have great potential for analysis and knowledge generation beyond the purposes for which they were collected and intended. However, there are still barriers in this process. To explore this problem, we have developed a prototype tool: the Experiment Dashboard (ED), with the objective of demonstrating the ability and potential of enabling automated data ingestion from typical research laboratories. This innovative prototype was developed to create a novel system and artifact to explore the possibilities of allowing researchers in laboratories across the nation to link their data acquisition systems directly to structured data repositories for data and metadata ingestion. The prototype functions with commonly used data acquisition software at the data source and the HUBzero scientific gateway at the data sink. ED can be set up with minimal effort and expertise. In this paper, we describe the motivation and purposes for the prototype, the architecture we devised and functionality of this tool, and provide a demonstration of the tool for optical measurements in a structural engineering laboratory. The goal of this paper is to articulate and show through our prototype a vision for future cyberinfrastructure for empirical disciplines that rely on the rapid collection, analysis, and dissemination of valuable experimental data. We also discuss lessons learned that may be useful for others seeking to solve similar problems. [ABSTRACT FROM AUTHOR]

The selective catalytic oxidation of ammonia (NH 3 -SCO) is currently the most effective method used to eliminate NH 3. However, one of the major challenges for NH 3 -SCO is the development of catalyst capable of completely converting NH 3 into harmless N 2 and water vapor. In this paper, a high N 2 selective catalyst prepared by the sol-gel method using TiO 2 as the support, Cu as the active species, and Sm as the auxiliary agent is presented. Compared to traditional Cu/TiO 2 catalyst, the 4SmCu/TiO 2 catalyst has higher catalytic activity and N 2 selectivity at low temperatures. The NH 3 conversion can reach 100%, and the selectivity of N 2 can be maintained at 100% at 275 °C. The excellent catalytic activity is attributed to the highly dispersed active species, abundant Lewis acid sites (LASs), and the generation of large amounts of surface-adsorbed oxygen. In addition, doping Sm species will cause TiO 2 lattice distortion, and at the same time load the distorted TiO 2 with more active material. Moreover, in-situ DRIFTS analysis suggests that both the 4SmCu/TiO 2 and Cu/TiO 2 catalysts follow the "internal" selective catalytic reduction (iSCR) mechanism during NH 3 -SCO reactions. The 4SmCu/TiO 2 catalyst generates more amides (-NH 2), which reduces the non-selective oxidation of the catalysts and promotes the formation of N 2. This provides a new idea and method for the selective catalytic oxidation of NH 3 to N 2 and water vapor using Cu-based catalysts. [Display omitted] • 4SmCu/TiO2 catalyst converts all NH3 into N2 and water vapor at 275 ℃. • The lattice distortion of TiO2 can support more active species. • Doping of Sm species increased the content of Lewis acid site and surface-adsorbed oxygen. • The rich amide intermediates reduce the non-selective oxidation of NH3 and O2.
