□ Course Outline

This course provides the understanding of the synthesis mechanisms of nanostructured materials, and exploits the synthesis methodology of organic-inorganic hybrid technologies for use in the energy conversion and storage devices.  The principles, materials, and device fabrications in battery, solar cell, fuel cell, and white LED will be discussed in this lecture.

3. Student Presentations (4-6 wks)

Projects

Overview

You are required to learn a specific research topic, and to communicate your ideas, both in presentation and writing, to other peers and to myself.  These skills are crucial for anyone disciplined in becoming an independent leader in the human society.

Topic

The presentation topic should be from a prestigious journal, such as Nature, Science, Angewandte Chemie, Appl. Phys. Lett., J. Appl. Phys., Chem. Mater., J. Phys. Chem. B, Nano Lett., etc. (SCI IF higher than 2.00).  You should give me a pdf file of the journal paper, which will be loaded on http://bp.snu.ac.kr for other classmates.

Identify and explore an active research topic involving nanostructures.  Choose an area that you feel will have a strong scientific or technological impact after your B.S. degree.

In one selected topic in materials for energy, you should criticize the characterization of nanostructures and the correlated physical/chemical properties.

Oral Presentation / Discussion

"If you were to be a reviewer of the journal, would you accept or reject the paper?  Why?"  You should point out any controversial and questionable issues, and describe how you would improve the current paper and understanding.  Never blindly copy a paper.

Each talk will be limited to 20 minutes, including presentation and questions/discussion from every attendee.  You use maximum 10 transparencies (ppt).  In each transparency, basic concepts/ideas should be clearly conveyed by the speaker.

Please bring your own computer and hardcopy of your 10-page presentation.

Term Paper

Compose a well-written paper about your topic, and the theme is the same as your oral presentation.  In your paper, please provide a literature review of previous studies, identify key unanswered research questions, and suggest promising research directions.
