Division/Committee: [COLL] Division of Colloid & Surface Chemistry

Colloidal nanoparticles represent an important class of structural and functional building block for many technologically significant materials and devices. However, technologies that leverage the structural advantages of individual nanoparticles have not been fully realized and have been limited by synthesis method. Fundamental issues related to chemical precursors, size, shape, and core/shell structure, surface chemistry, etc. critically determine the property and applications of nanoparticles and their assemblies. To address these issues, this symposium will cover the general topics of colloidal nanoparticle synthesis and assembly. Specifically, this symposium will focus on (1) nucleation and growth for crystal growth and to manipulate nanoparticle size, shape, and core/shell structure; (2) structural and property characterizations of nanoparticles; (3) Integration of nanoparticles in nanoelectronics and nanophotonics; and (4) Advanced spectroscopy and transport studies on optical, electronic, and magnetic structure, carrier dynamics, of nanoparticles/nanowires. The topics covered include: • Nanoparticle surface chemistry/functionalization to manipulate particle interactions, packing symmetry, external framework, and property; • Large area of self-assembled nanoparticle arrays and patterning with long range order; • In-situ characterizations of nanoparticle nucleation, growth, and self-assembly; • Characterization of structure and property of self-assembled nanoparticle arrays
