9313813 Zeyen Replacement of a 15 year old energy dispersive X ray Micronanalysis Unit (XRMA) on an existing scanning electron microscope, and addition of a detector and remote workstation to a newly acquired analytically configured transmission electron microscope are the proposal objectives. Replacement instrumentation is for campus wide research and student training on the St. Paul Campus of the University of Minnesota. The XRMA replacement sought is a workstation based analyzer capable of simultaneous energy dispersive X ray microanalysis from two light element detectors installed on existing instruments located in separate rooms. The replacement instrumentation would also provide for electronic image capture and storage, image analysis capabilities, and have a networking interface with Ethernet. The requested replacement instrument is an integral part of current and future campus wide biological and life science research needs. On going student training and research capabilities would be greatly enhanced by "state of the art" replacement instrumentation. Current research efforts, with state and national priorities, benefiting immediately from the proposal for a replacement instrument are: a) Wood decomposition and bioprocessing of lignin removal for paper products; b) Disease and pest resistance in plants; c) Elemental distribution research in plants aimed at reducing fertilizer needs; d) Forest water quality and applied ecology of lakes, streams and rivers; and, e) Atmospheric acid deposition and pesticide residue research in soil chemistry and physics. Replacement instrumentation is to be located in the Cooperative Electron Optics Facility (CEOF) in the Christensen Laboratory building on the St. Paul Campus. This multiple user facility has been in operation since 1969, is supported by the Minnesota Agricultural Experiment Station, and serves campus wide needs in analytical electron microscopy and XRMA. The CEOF is centrally located on the St. Paul Campus, has 11 rooms, 2 ultramicrotomes, vacuum evaporators, darkrooms and preparation laboratories. No renovation or remodeling is necessary to accept the proposed instrument replacement. u ~ s t # # # # # # # # # # # # # e# # # #!#"###$#%#&#'#(#)#*#+#,#-#.#/#0#1#2#3#4#5#6#7#8#9#:#;##=##?#@#A#B#C#D#E#F#G#H#I#J#K#L#M#N#O#P#Q#R#S#T#U#V#W# Y#Z# #\# #^#_#`#a#b#c#d# f#g#h#o# # m#n# p#q#r#s#t# y# # # # # # # # # # 9313813 Zeyen Replacement of a 15 year old energy dispersive X ray Micronanalysis Unit (XRMA) on an existing scanning electron 6 8 ! ! ! ! !

9313813 Zeyen在现有的扫描电子显微镜上更换一个使用了15年的能量色散X射线衍射分析单元（XRMA），并在新获得的分析配置透射电子显微镜上增加一个检测器和远程工作站是提案的目标。更换仪器是为校园范围内的研究和学生培训的圣保罗校园的明尼苏达大学。所寻求的XRMA替代品是一种基于工作站的分析仪，该分析仪能够从安装在位于不同房间的现有仪器上的两个轻元素探测器同时进行能量色散X射线微量分析。更换的仪器还将提供电子图像捕获和存储、图像分析能力，并具有与以太网的联网接口。所要求的更换仪器是当前和未来校园范围内生物和生命科学研究需求的一个组成部分。 正在进行的学生培训和研究能力将大大提高了“国家的最先进的”更换仪器。目前的研究工作，包括州和国家的优先事项，直接受益于关于替代文书的建议，是：a）木材分解和生物处理去除木质素用于纸制品; B）植物的疾病和害虫抗性; c）植物中的元素分布研究，旨在减少肥料需求; d）森林水质和湖泊、溪流和河流的应用生态学;（e）大气酸沉降和土壤化学和物理学中的农药残留研究。 替换仪器将位于圣保罗校区克里斯滕森实验室大楼的电子光学合作设施（CEOF）中。这个多用户设施自1969年以来一直在运行，由明尼苏达州农业实验站支持，并满足校园范围内的分析电子显微镜和XRMA的需求。CEOF位于圣保罗校区的中心，有11个房间，2个超薄切片机，真空蒸发器，暗室和制备实验室。无需翻新或改造即可接受拟议的手术工具更换。 u ~ s t # # e#！# "###$#%##'#(#)#*#+#,#-#.#/# 0#1#2#3#4#5#6#7#8#9#：#;##=##？#@# A#B#C#D#E#F#G#H#I#J#K#L#M#N#O#P#Q#R#S#T#U#V#W# Y#Z#\#^#_#`#a#B#c#d# f#g#h#o# # m#n# p#q#r#s#t# y编号 # # # # # # # # # 9313813 Zeyen在现有的扫描电子显微镜上更换使用了15年的能量色散X射线衍射分析装置（XRMA） 6 8 ! ! ! ! !
