Catalog Description, Prerequisites and Schedule:

Introduces the fundamentals of glass science and technology. Provides a comprehensive overview of the ubiquitous phenomena associated with the amorphous state of matter, including glass transition and viscous relaxation, as well as the mechanical, optical, and dielectric properties of glasses. These behaviors are discussed in the context of different thermodynamic, structural, and kinetic models. The use of various characterization techniques to understand the glassy state, are reviewed. Different methods for processing, forming, and treatment of glasses are contrasted, using examples of conventional and new high-technology applications.

Course Objectives:

1. Impart the basic knowledge about the distinctive features of the amorphous state of matter.
2. Instruct students on issues of glass formation, processing, and various chemical and thermal treatments.
3. Convey the relationships between processing, structure, and physical properties of glasses.
4. Provide students with an overview of novel technological applications of glasses.
5. Give students an appreciation of the importance that materials design has for technological advancement, and the great flexibility that glassy materials posses in this context.

Course Outcomes:

1. Students know how to synthesize, process, and heat-treat glasses.
2. Students know the methods for structural characterization of amorphous materials.
3. Students understand the ubiquitous features of the structure in glasses and liquids, and how these relate to their properties.
4. Students have learned how to select materials for a wide range of optical, electrical, structural, and other functional applications.
5. Students have learned strategies to achieve desired materials properties by altering chemistry and processing conditions.

Assessment Tools:

1. Three take home exams, requiring the review of all course subjects covered in class. Exams are composed of knowledge-based questions and problems requiring numerical calculations.
2. Term paper consisting of researching a particular subject in glass science and technology. Papers are to be based on the review of the pertinent literature. Students give a short presentation on their papers towards the end of the semester. After addressing editorial comments by the instructor, the collected papers are bound and distributed to all students. Evaluation is based on:
a. Communication skill exhibited during the presentation as well as in the written document.
b. The detail, extent, and completeness to which the subject is covered in the paper.
