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.

化学（12）物理（13）这个项目涉及一个新的两学期的实验室课程，为本科生在化学和材料物理，开发和教授的化学和物理系联合。 无论是固体状态还是一般材料都没有很好地涵盖在任何部门的现有产品，所以它是有意义的安装共同努力，教育学生在这个领域的巨大和日益增长的重要性，在科学和技术，一个跨越传统学科界限。 该项目侧重于实验室工作，适合化学，物理或化学物理专业的课程，并融合了化学家和物理学家的方法。 特别注意材料的合成;无机和有机物质都被考虑在一起，并作为实验室工作的例子，重点放在有用的性能和技术应用上。（例如高Tc超导体; V2 O 4; MoS 2）;纯化晶体生长;结构描述和分析;用X射线粉末衍射法鉴定和测定物质的结构;表面成像（例如扫描隧道显微镜）;固体的机械、电学、磁学和光学性质（例如解理;压电性;半导体;有机导体;铁电性;磁化率;反铁磁性;超导性;双折射;非线性光学性质）;以及软凝聚物质（例如液晶）的各种性质。 一些实验是改编自化学或物理教育文献中发表的实验，一些新的实验正在开发中，以创建一个适当的整体介绍材料科学。 学生进行简短的个人和/或小组研究项目，并就选定的主题进行演讲。 巴纳德学院的化学和物理教师正在结合和分享他们的专业知识，哥伦比亚大学的材料研究科学与工程中心也在提供帮助。
