Support of UIC X-ray Diffraction Faciliites

9612878古根海姆这笔拨款提供48355美元，作为伊利诺伊大学芝加哥分校升级单晶和粉末x射线衍射（XRD）仪器费用的一半支持。对单晶仪器的升级将包括一个新的进动相机，自动化软件和一个处理X射线图像的新工作站。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，一个水循环器和新的x射线管。这些仪器的升级是有充分理由的，并将允许在广泛的温度和压力范围内对层状硅酸盐矿物学和晶体学进行持续的富有成效的研究，研究有机分子与粘土矿物之间的吸附/解吸附反应，碳酸盐-水流体相互作用的实验岩石学，研究锰氧化物与废水中有机化合物相互作用的溶解动力学。半导体表面表征及催化剂表征。因此，这些升级将有利于各院系教员、物理、化学和化学工程系教员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. ***
