Scanning Probe Microscopy and Molecular Modeling in the Undergraduate Chemistry Laboratory Curriculum

我们项目的总体目标是：(i)通过展示实验的基本原理在当前科学、技术和公众感兴趣的领域中的作用来振兴本科化学实验室教学；（ii）让学生在理解宏观现象时，将原子、分子和现象的相关性联系起来；（iii）从实验课程的研究文献中采用在讲座设置和实验中证明成功的方法。为了达到这些目标，我们正在调整、实施和发展不同层次的本科化学实验课程。这些实验将扫描探针显微镜的原子和分子分辨率与分子建模相结合，将微观现象与宏观应用联系起来。这些实验证明了基础科学的基本原理与应用科学领域的相关性，例如纳米技术，在纳米技术中，理解原子和分子水平的过程对于设计下一代电子设备至关重要。许多实验都是改编自研究文献的实验，向学生展示科学的过程。通过这些实验，我们期望学生们能够更好地理解和欣赏科学的跨学科性质以及科学、工程和技术之间的相互作用。该项目影响到哥伦比亚大学的所有理工科本科生，这是一个多元化的种族人口，在性别方面混合均匀。为了进一步扩大参与的学生群体，我们还与诺福克州立大学（Norfolk State University）的化学教师合作，这是一所历史悠久的黑人大学。

Chemistry (12) The overarching goals of our project are: (i) to revitalize undergraduate chemistry laboratory instruction by demonstrating the role of underlying principles of experiments to areas of current scientific, technological, and public interest; (ii) to allow students to relate the relevance of atomic and molecular and phenomena in understanding macroscopic phenomena; (iii) to adapt methods proven successful in lecture settings and experiments from the research literature in the laboratory curriculum.. To achieve these goals, we are adapting, implementing and developing experiments for undergraduate chemistry laboratory courses at different levels. These experiments combine the atomic and molecular resolution of Scanning Probe Microscopy with molecular modeling to relate microscopic phenomena to macroscopic applications. The experiments demonstrate the relevance of fundamental principles of basic science to areas of applied science, such as nanotechnology, where understanding atomic and molecular-level processes is critical in designing the next generation electronic devices. Many of the experiments are adaptations of experiments derived of the research literature, demonstrating to students the process of science. By performing these experiments, we expect that students will develop a greater understanding and appreciation of the interdisciplinary nature of science and the interplay between science, engineering, and technology. The project affect all science and engineering undergraduate students at Columbia University, a diverse ethnic population evenly mixed in terms of gender. To further broaden the population of students involved, we are also collaborating with chemistry faculty at Norfolk State University, a historically black institution.
