Support of UIC X-ray Diffraction Faciliites

小行星9612878 这笔赠款提供了48 355美元，作为芝加哥伊利诺斯大学单晶和粉末X射线衍射仪升级费用的一半。 单晶仪器的升级将包括一个新的旋进相机，自动化软件和一个新的工作站来处理X射线图像。 粉末XRD仪器的升级将包括自动化软件，这需要一个PC平台、一个薄膜附件、一个新的相机和一个水再循环器以及一个新的X射线管。 对这些仪器进行升级是完全合理的，将允许在广泛的温度和压力范围内继续对层状硅酸盐矿物学和晶体学进行富有成效的研究，研究有机分子和粘土矿物之间的吸附/解吸反应，碳酸盐-含水流体相互作用的实验岩石学，由于与废水沃茨中有机化合物的相互作用，氧化锰溶解的动力学研究，半导体表面的表征和催化剂的表征。 因此，这些升级将有利于部门教师和物理，化学和化学工程部门以及区域用户进行的广泛研究。 ***

9612878 Guggenheim This grant provides $48,355 as one-half support of the costs of upgrading the single crystal and powder X-ray diffraction (XRD) instruments at the University of Illinois at Chicago. Upgrades to the single crystal instrument would include a new precession camera, automation software and a new workstation to process X- ray images. Upgrades to the powder XRD instrument would include automation software which requires a PC platform, a thin film attachment, a new camera and a water recirculator and new X-ray tube. Upgrades to these instrument were well justified and will allow continued productive research on phyllosilicate mineralogy and crystallography over a wide range of temperatures and pressures, studies of the adsorption/desorption reactions between organic molecules and clay minerals, experimental petrology of carbonate-aqueous fluid interactions, studies of the kinetics of manganese oxide dissolution as a result of interactions with organic compounds in waste waters, characterization of semiconductor surfaces and characterization of catalysts. These upgrades will therefore benefit a wide range of research conducted both by departmental faculty and by faculty from the Departments of Physics, Chemistry, and Chemical Engineering as well as by regional users. ***
