9977715Abstract This project involves the acquisition, installation and use of a low vacuum, high resolution scanning electron microscope (SEM) with cryostage and x-ray microanalysis capabilities. There are currently over 30 scientists and a significant number of students and post-doctoral fellows on the campus of Kansas State University using SEMs for research in biological, physical, chemical and engineering specimens. None of the SEMs currently available is state-of-the-art and several of them are outdated, very difficult to use and maintain and provide relatively poor image quality. The new SEM will revitalize these research programs providing them with modern imaging capabilities and the ability to image in low vacuum, cryo-conditions and with x-ray microanalysis. This microscope will be used for research in a broad range of areas including insect genetic regulatory mechanisms; sensory receptors and cues for oviposition by moths and butterflies; geotechnical/geoenvironmental engineering; molluscan biomineralization; analysis of extruded food products; synthesis, properties and applications of hydrogels; function of insect blood cells; phenotypes of mutant Arabidopsis floral organs; and plant defense response and regulated secretions.

9977715摘要该项目涉及购置、安装和使用具有冷冻台和X射线微量分析功能的低真空、高分辨率扫描电子显微镜（SEM）。 目前有超过30名科学家和相当数量的学生和博士后研究员在校园内的堪萨斯州立大学使用SEM的生物，物理，化学和工程标本的研究。 目前可用的SEM中没有一个是最先进的，其中一些已经过时，非常难以使用和维护，并且提供相对较差的图像质量。 新的扫描电镜将振兴这些研究项目，为他们提供现代成像能力和在低真空、低温条件下成像的能力，并进行X射线显微分析。 该显微镜将用于广泛领域的研究，包括昆虫遗传调节机制;蛾和蝴蝶产卵的感觉受体和线索;岩土工程/地质环境工程;软体动物生物矿化;挤压食品分析;水凝胶的合成、性质和应用;昆虫血细胞的功能;突变拟南芥花器官的表型;以及植物防御反应和调节分泌。
