This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The Inorganic, Bioinorganic and Organometallic Chemistry Program supports the research of Professor Douglas Vander Griend of Calvin College for the in situ characterization of multi-component chemical solutions. Equilibrium Restricted Factor Analysis, a mathematical technique for modeling such complex solutions, allows information to be ascertained about the number and nature of specific chemical species without the need to chemically isolate them. This approach employs spectrophotometric titrations in the study of: 1) step-by-step assembly processes for supramolecular cubes based on 1st row transition metals, 2) precise thermodynamic interactions between the parts of a pseudo-rotaxane nanomachine, and 3) nickel complexes which demonstrate thermochromic properties. Like many potential applications in chemistry today, these systems showcase different types of molecular organization that can be difficult to characterize by conventional means. The proposed thermochromic windows that tint in response to sunlight are expected to lead to substantial energy savings. Undergraduates at all levels will work with Professor Vander Griend to learn a plethora of laboratory skills and develop chemical intuition through comprehensive involvement in the project. These students also regularly interact with collaborators at graduate and industrial laboratories.

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)提供资金的。无机化学、生物无机化学和金属有机化学项目支持卡尔文学院道格拉斯·范德·格里德教授对多组分化学溶液的现场表征研究。平衡限制因素分析是一种对这类复杂溶液进行建模的数学技术，它允许确定关于特定化学物种的数量和性质的信息，而不需要将它们化学隔离。这种方法使用分光光度滴定来研究：1)基于第一排过渡金属的超分子立方体的逐步组装过程，2)假轮烷纳米机器部件之间的精确热力学相互作用，以及3)表现出热致变色特性的镍配合物。就像当今化学中的许多潜在应用一样，这些系统展示了不同类型的分子组织，这些组织很难用传统方法来表征。拟议中的热致变色窗对阳光的反应将产生显著的节能效果。所有级别的本科生将与Vander Griend教授一起学习过多的实验室技能，并通过全面参与该项目来发展化学直觉。这些学生还定期与研究生和工业实验室的合作者互动。
