This CAREER award to Christopher C. Landry at the University of Vermont is supported by the Advanced Materials Program in the Chemistry Division. The research deals with the synthesis, characterization and catalytic and chromatographic behavior of mixed phase microporous/mesoporous silicates and aluminosilicates. The mixed phases will be prepared by initial polymerization of a silicate source in the presence of an organic micellar template in aqueous solution and room temperature to form a weakly-organized mesoporous material. This material will be subsequently heated in the presence of a structure-directing agent, typically tetrapropyl ammonium cation, to form a microporous material. Incomplete annealing will produce mixed mesoporous/microporous composites. Structure, as a function of reaction variables will be explored. XRD, NMR, IR, SEM, TEM and porosimetry will be employed to characterize the mixed phases. The materials will be evaluated as catalysts for olefin isomerization and as chromatographic supports.The CAREER educational plan will focus on the inclusion of Materials Chemistry into both graduate and undergraduate curricula. Courses in Materials Chemistry will be developed which will also utilize local faculty and industrial scientists as resources. Classes and special lectures will be electronically disseminated through the University's Distance Learning Network, permitting both graduate students and industrial scientists at remote locations to earn credit towards advanced degrees. The program will include examples from Prof. Landry's research and other local industrial projects and is expected to stimulate industrial-academic research partnerships.

该职业奖授予佛蒙特大学的Christopher C. Landry，由化学学部先进材料项目资助。研究了混合相微孔/介孔硅酸盐和铝硅酸盐的合成、表征及其催化色谱行为。混合相将在有机胶束模板存在的情况下，在水溶液和室温下通过硅酸盐源的初始聚合制备，形成弱组织的介孔材料。该材料随后将在结构导向剂（通常是四丙基铵阳离子）的存在下加热，以形成微孔材料。不完全退火将产生混合介孔/微孔复合材料。结构，作为反应变量的函数将被探讨。采用XRD、NMR、IR、SEM、TEM和孔隙度法对混合相进行表征。这些材料将作为烯烃异构化催化剂和色谱载体进行评价。CAREER教育计划的重点是将材料化学纳入研究生和本科课程。将开发材料化学课程，并利用当地教师和工业科学家作为资源。课程和特别讲座将通过大学的远程学习网络以电子方式传播，允许研究生和远程地点的工业科学家获得高级学位的学分。该计划将包括兰德里教授的研究和其他本地工业项目的例子，并有望促进工业与学术研究的合作。
