Group Travel for U.S. Participants at Seventh International Conference on Small-Angle Scattering (Prague, 13-16 July 1987)

为参加将于1987年7月13日至16日在捷克斯洛伐克布拉格举行的第七届小角散射问题国际会议的大约11名美国与会者提供总计高达10,000美元的旅费支持。会议的主题是小角X射线(SAXS)和中子(SANS)散射的理论、仪器和应用。这两种技术在材料科学(陶瓷、金属、合金等)中都有应用。聚合物科学(混合物、混合物、溶液等)、分子生物学(膜结构、溶液中的蛋白质、核酸等)、催化和化学应用(结构、孔隙率、粒度分布、表面积等)、临界现象和凝聚态物理。如果美国想要赶上欧洲科学家在过去十年中在SANS和SAXS方面设定的步伐，美国科学家的参与是必不可少的。目前在美国，反应堆和脉冲中子源都有六个SANS设施。几个高通量同步加速器设备现已可用于SAXS。它的目的是只支持那些将在会议上提交论文和/或充分履行重要技术职能的与会者。申请将通过提案中概述的程序严格筛选科学价值。将提供最终报告，确定得到支持的美国科学家，并描述会议的科学亮点。每个接受支持的人还将提供一页的经验总结。这是为热力学和传输现象及聚合物项目共同资助的赠款。

Travel support of up to a total of $10,000 is provided for approximately 11 U.S. participants in the 7th International Meeting on Small-Angle Scattering, to be held July 13-16, 1987 in Prague, Czechoslovakia. Topics of the conference are the theory, instrumentation and application of small angle x-ray (SAXS) and neutron (SANS) scattering. Applications of both these techniques are found in materials science (ceramics, metals, alloys, etc.) polymer science (mixtures, blends, solutions, etc.), molecular biology (membrane structure, proteins in solutions, nucleic acids, etc.), catalysis and chemical applications (structure, porosity, size distributions, surface areas, etc.), critical phenomena and condensed matter physics. Participation by U.S. scientists is essential if the U.S. is to match the pace set in the last decade by the European scientists in both SANS and SAXS. Currently in the U.S. there are six SANS facilities at both reactor and pulsed neutron sources. Several high flux synchrotron source facilities are now available for SAXS. It is intended to support only those participants who will present papers and/or fullfill a significant technical function at the conference. Applications will be screened rigorously for scientific merit by a procedure outlined in the proposal. A final report will be provided identifying the U.S. scientists that were supported and describing the scientific highlights of the meeting. Each person receiving support will also provide a one-page summary of their experiences. This is a jointly funded grant for Thermodynamics and Transport Phenomena and Polymers Programs.
