2015-2016 Academic Year

Fall 2015

CHEM 141 Foundations of Chem w/Lab
A one-semester introductory course for students who are especially well-prepared for general chemistry, replacing CHEM 131, 132 as a prerequisite for more advanced courses in the major. Topics include atomic structure, chemical bonding, thermodynamics, kinetics, equilibrium, electrochemistry, acid/base chemistry, solubility, and transition metal chemistry. The laboratory experiments will relate directly to topics covered in lecture, and will include statistical analysis of data, molecular modeling, instrumental methods of analysis, and quantitative analytical and inorganic chemistry. Admittance into this course is based on a placement exam. Three hours of classroom and three hours of laboratory per week.

Spring 2016

CHEM 200 Analysis Antiox/Phyto in Food
In this laboratory-based course, we will investigate antioxidants, vitamins and other phytochemicals present in foods. Student-based research questions will drive the specific analyses and techniques employed, which may include colorimetric assays, titrations, and chromatographic or spectroscopic techniques. In consultation with the Dickinson College Farm, we will consider how agricultural practices affect the quality and properties of fruits and vegetables.

CHEM 244 Equilibrium Systems w/Lab
The fundamentals of chemical thermodynamics will be presented with a view towards providing an understanding of the concept of chemical equilibrium. Introductory concepts in chemical kinetics will also be discussed. Laboratory will focus on experiments illustrating the principles of thermodynamics and chemical kinetics. Three hours classroom and four hours laboratory per week. Prerequisites: 132 or 141, MATH 171 or concurrent enrollment.

CHEM 490 Nanomaterials
Materials, such as polymers, metals, alloys, ceramics, and semiconductors, are substances that have useful, often customizable properties. Nano-materials are materials that have at least one dimension that is measured as less than 1000 nm, although 100 nm may be a more appropriate upper limit. Nanomaterials often display properties that are quite different than their macroscale counterparts—these can include changes in electrical, thermal, magnetic, and physical phenomena. These surprising new properties manifest based on size alone, and nano-phenomena are rich ground for scientific discoveries and technological applications. Indeed, nanomaterials have already begun to alter medicine, electronics, energy generation/storage, and even the most mundane aspects of daily life. In this course, we will investigate the origins of nano-phenomena in materials and investigate their synthesis and applications from a chemical point of view.
