A New Laboratory Course in the Chemistry and Physics of Materials

化学(12)物理(13)这个项目包括一门新的为期两个学期的实验室课程，由化学和物理系联合开发和教授，面向材料化学和物理专业的本科生。这两个系的现有课程都没有很好地涵盖固体和材料，因此联合努力在这个跨越传统学科界限的巨大且日益重要的科学技术领域对学生进行教育是有意义的。该项目将重点放在一门适合化学、物理或化学物理专业的课程中，并融合了化学家和物理学家的方法。特别注重材料的合成，将无机和有机物质放在一起考虑，并在实验室工作中用作实例，重点放在有用的性质和技术应用上。合成方面的实验正在进行中(例如高T_c超导体；V204；MoS_2)；提纯(例如区域细化)；晶体生长；结构描述和分析；通过X射线粉末衍射鉴定和确定物质的结构；表面成像(例如扫描隧道显微镜)；固体的机械、电、磁和光学性质(例如解理；压电性；半导体；有机导体；铁电性；磁化率；反铁磁性；超导；双折射；非线性光学性质)；以及软凝聚体的各种性质(如液晶)。一些实验正在根据化学或物理教育文献中发表的实验进行改编，一些新的实验正在开发中，以便对材料科学进行适当的全面介绍。学生完成简短的个人和/或小组研究项目，并就选定的主题发表演讲。巴纳德学院的化学和物理教职员工正在结合和分享他们的专业知识，哥伦比亚大学材料研究科学和工程中心也提供帮助。

Chemistry (12) Physics (13) This project involves a new two-semester laboratory course for undergraduates in the chemistry and physics of materials, developed and taught jointly by the Departments of Chemistry and Physics. Neither the solid state nor materials in general were well covered in the existing offerings of either department, so it makes sense to mount a joint effort to educate students in this area of immense and growing importance in science and technology, one that cuts across traditional disciplinary boundaries. The project focuses on laboratory work in a course suitable for majors in chemistry, physics, or chemical physics, and blends the approaches of both chemists and physicists. Special attention is paid to the synthesis of materials; both inorganic and organic substances are considered together and used as examples in laboratory work, and emphasis is placed on useful properties and technical applications.Experiments are being developed in synthesis (e.g. high Tc superconductors; V204; MoS2); purification (e.g. zone refining); crystal growth; structure description and analysis; identification and structure determination of substances by X-ray powder diffraction; surface imaging (e.g. scanning tunneling microscopy); the mechanical, electrical, magnetic, and optical properties of solids (e.g. cleavage; piezoelectricity; semi-conduction; organic conductors; ferroelectricity; magnetic susceptibility; anti-ferromagnetism; superconductivity; birefringence; nonlinear optical properties); and various properties of soft condensed matter (e.g. liquid crystals). A number of experiments are being adapted from ones which have been published in the chemical or physics education literature, and some new experiments are being developed, in order to create an appropriate overall introduction to materials science. Students perform short individual and/or group research projects, and present talks on selected topics. Chemistry and Physics faculty members at Barnard College are combining and sharing their expertise, and the Materials Research Science and Engineering Center of Columbia University also is providing assistance.
