3 Course Covers This class introduces advanced physical chemistry as an interdisciplinary subject. It reviews covers the latest development of modern chemistry and physics within the context of nanoscale science and technology. State-of-the-art experimental approaches such as instruments to prepare and characterize nanostructures and the guiding principles will be discussed as well. 1. Modern chemistry Chemistry from a different perspective Chemistry and nanotechnology 2. Nanostructured materials Bulk materials with nanostructures Low dimensional materials Mesoporous materials Preparation methods (synthesis) 4. Characterizations and properties Structural information Chemical information Physical properties Electrical properties 5. Applications State-of-the-art experimental Industrial applications 3. Physical chemistry of nanomaterials Quantum confinement Physical chemistry of solid surfaces New sciences of nanomaterials

4 Literature No specific textbooks will be required for the course. Supplementary materials such as useful chapters of reference books and latest papers critical to the class will be distributed as handouts. Suggested readings 1. Cao: Nanostructures and nanomaterials (Imperial College Press, 2004) 2. Hummel: Electronic properties of materials (Springer, 2000) 3. West: Basic Solid State Chemistry (Wiley, 1999) 4. Kelsall: Nanoscale Science and Technology (Wiley, 2005) 5. Klabude: Nanoscale Materials in Chemistry (Wiley, 2009)

5 Requirements Mandatory attendance (10%); Quizzes (20%); Problem sets (20%); Two exams (30%); The final presentation (20%). Problem sets, exams, and quizzes: Problem sets will be distributed during the semester. They will be distributed on the website and should be completed by the following week. The problem sets have to be handed in during the class. There will be in-class quizzes lasting ~15 minutes. There will be two in-class exams during the course of the semester, each lasting ~90 minutes. The quiz will be held randomly and the two exams will be held on October 3 st and November 7 th. Presentations: There will be a final in-class presentation in the end of the semester. The ~15 min presentation will be on a paper of your choice from the current literature (2009-present). The list of proper journals is provided on the website.

13 What is Nanotechnology (Nanoscience)? "Νανο" derives from the Greek word for dwarf. Technologies dealing with materials with at least one dimension with length scales in nanometer. 1 nm = 1*10-9 m (one billionth of a meter) one nanometer (one billion of a meter) is a magical point on the dimensional scale. Nanostructures are at the confluence of the smallest of human-made devices and the largest molecules of living things. Nanoscale science and engineering here refer to the fundamental understanding and resulting technological advances arising from the exploitation of new physical, chemical and biological properties of systems that are intermediate in size, between isolated atoms and molecules and bulk materials, where the transitional properties between the two limits can be controlled.
