Selected AbstractsPortal-based Knowledge Environment for Collaborative ScienceCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 12 2007Karen Schuchardt Abstract The Knowledge Environment for Collaborative Science (KnECS) is an open-source informatics toolkit designed to enable knowledge Grids that interconnect science communities, unique facilities, data, and tools. KnECS features a Web portal with team and data collaboration tools, lightweight federation of data, provenance tracking, and multi-level support for application integration. We identify the capabilities of KnECS and discuss extensions from the Collaboratory for Multi-Scale Chemical Sciences (CMCS) which enable diverse combustion science communities to create and share verified, documented data sets and reference data, thereby demonstrating new methods of community interaction and data interoperability required by systems science approaches. Finally, we summarize the challenges we encountered and foresee for knowledge environments. Copyright © 2007 John Wiley & Sons, Ltd.

As a part of the IAEA's role in fostering the peaceful uses of nuclear science and technology, the IAEA's Division of Physical and Chemical Sciences has focused attention on the important classes of compounds such as, fluorine-18 products; technetium-99m labelled complexes; products for radionuclide therapy of yttrium-90, samarium-153, lutetium-177 and rhenium-186/188; industrial radiotracers based on bromine-82 labelled compounds, tritiated water and carbon-14 labelled thiocyanate. A number of coordinated research projects (CRP) and technical cooperation projects have been implemented for this purpose. Thematic technical and consultancy meetings have been held to review the status and prepare technical documents on specific topics of interest for developing Member States (MS). These measures have contributed to several developing MS acquiring/enhancing expertise in building local facilities and capability in the production and utilization of radioisotope labelled compounds.

[source] New Templating Strategies with Salen Scaffolds (Salen=N,N,-Bis(salicylidene)ethylenediamine Dianion)CHEMISTRY - A EUROPEAN JOURNAL, Issue 34 2008Arjan Abstract Templated approaches towards selective organic synthesis is a common feature in nature in which nucleic acid templated synthesis plays a crucial role in various fundamental biological processes. The key feature that allows control over the amazing selectivity found in natural processes is evidently the effective molarity of the reaction partners that is mediated by the macromolecular templation event. An ongoing challenge within many chemical sciences is to exploit similar templating principles and make use of synthetic systems that are designed for specific chemical conversions. Here, we describe the recent developments that involve (metallo)salen scaffolds that are used for diverse templating events (salen=N,N,-bis(salicylidene)ethylenediamine dianion). [source] | ||||||||||
