Replacement instrumentation is proposed for campus-wide research and student training on the St. Paul campus of the University of Minnesota. The TEM replacement sought is an analytically configured TEM with microprocessor controls, electronic image capture and analysis capabilities, and a light element detector and analyzer. On-going student training and research capabilities would be greatly enhanced by state-of-the-art instrumentation. Current research efforts, with state and national priorities, benefiting immediately from the proposal are: a) Soil chemistry and physics related to atmospheric acid deposition and pesticide residues; b) Wood decomposition and bioprocessing of lignin removal for paper product; c) Nitrogen fixation by plants to reduce fertilizer needs; d) Forest water quality and applied ecology; e) Development and disease resistance in plants; and, e) Food quality and structure research.

替换仪器被提议用于明尼苏达大学圣保罗校区的校园范围内的研究和学生培训。TEM的替代品是一种分析配置的TEM，具有微处理器控制，电子图像捕获和分析能力，以及轻元素探测器和分析仪。最先进的仪器将大大提高正在进行的学生培训和研究能力。目前的研究工作，与州和国家的优先事项，立即受益于该提案：a)土壤化学和物理有关的大气酸沉降和农药残留；b)木材分解和去除纸制品木质素的生物处理；c)植物固氮，减少肥料需求；d)森林水质与应用生态；e)植物的发育和抗病能力；e)食品质量与结构研究。
