With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at John Carroll University will acquire Isothermal Titration and Differential Scanning Calorimetry Instruments. This equipment will enhance research in a number of areas including a) characterization of the effect of nonpolar solutes on coulombic interactions; b) organic and organoalkali structure and reactivity; c) determination of protein structure at solid/liquid interfaces and examination of sol-gel synthetic routes to alumina films; d) measurement of binding strengths of various metals to organometallic fragments; and e) analysis of surfaces of powders. Differential Scanning Calorimetry (DSC) is an extremely useful tool in modern analytical chemistry. Calorimetric analysis is used to measure the thermal energy (heat) exchange that occurs during molecular interactions and reactions. Thus DSC provides a very reliable and sensitive method for determining the thermodynamic properties of materials such as changes in heat capacity of liquid and solid samples.

在主要研究仪器(MRI)计划的支持下，约翰·卡罗尔大学化学系将获得等温滴定和差示扫描量热仪器。该设备将加强若干领域的研究，包括a)表征非极性溶质对库仑相互作用的影响；b)有机和有机碱的结构和反应性；c)测定固/液界面的蛋白质结构和研究氧化铝薄膜的溶胶-凝胶合成路线；d)测量各种金属与金属有机碎片的结合强度；以及e)粉末表面的分析。差示扫描量热法(DSC)是现代分析化学中一种非常有用的工具。量热分析用于测量分子相互作用和反应过程中发生的热能(热)交换。因此，DSC提供了一种非常可靠和灵敏的方法来确定材料的热力学性质，如液体和固体样品的热容变化。
