9415675 Cartledge This U.S.-Brazil Cooperative Science Program award supports travel expenses and expendable research supplies for work to be conducted by Prof. F. Cartledge and Dr. M. Titlebaum, both of Louisiana State University (LSU), Louisiana, with Dr. P. Buchler, Univ. of Sao Paulo, Brazil. Drs. Cartledge, Titlebaum and Buchler are conducting research on the solidification/stabilization of hazardous wastes using cementitious binders, a common technology applied to waste streams, mostly of heavy metal containing wastes. The use of organoclays as additives in the process has the potential for greatly expanding the utility of the method, particularly for the treatment of mixed waste streams and contaminated soils, where organic as well as inorganic wastes are present. The research groups at LSU and Sao Paulo have unique and complementary capabilities. The LSU group is noted for experience with solid state nuclear magnetic resonance spectroscopy, while the Sao Paulo group has broad experience with real waste streams and the design of mixes that are effective for the immobilization of organic containing wastes. The proposed research will involve sample preparation in Brazil, and the examination of spectroscopic and other properties at LSU. The LSU group will benefit from the Brazilian groups' expertise in clay uses and modifications, while the Sao Paulo group will benefit from access to modern instrumentation for solid characterization. ***

9415675卡特利奇这项美国-巴西合作科学计划奖励为路易斯安那州路易斯安那州立大学（LSU）的F.卡特利奇教授和M. Titlebaum博士以及巴西圣保罗大学的P. Buchler博士进行的工作提供旅费和消耗性研究用品。Drs。Cartledge， Titlebaum和Buchler正在研究使用胶凝粘合剂固化/稳定危险废物，这是一种用于废物流的常用技术，主要是含重金属的废物。在该工艺中使用有机粘土作为添加剂有可能大大扩展该方法的用途，特别是用于处理混合废物流和污染土壤，其中存在有机和无机废物。路易斯安那州立大学和圣保罗大学的研究小组具有独特和互补的能力。路易斯安那州立大学研究组以在固态核磁共振波谱方面的经验而闻名，而圣保罗研究组在实际废物流和有效固定含有机废物的混合物的设计方面拥有广泛的经验。拟议的研究将包括在巴西制备样品，并在路易斯安那州立大学检查光谱和其他特性。LSU小组将受益于巴西小组在粘土使用和修改方面的专业知识，而圣保罗小组将受益于获得现代固体表征仪器。＊＊＊
