One-dimensional (1D) nanomaterials, including but not limited to nanowires, nanobelts and nanotubes, respresent an important and broad class of nanomaterials at the forefront of nanoscience and nanotechnology. The most reprehensive 1D nanomaterials, for example, are silicon nanowires and ZnO nanowires/nanobelts. 1d nanomaterials can be rationally and predictably synthesized in single crystal form with a ll key parameter controlled during growth: chemical composition, diameter, length, doping, growth direction, possibly surfaces, spatial distribution and patterning, and choice of substrates. 1d Nanomaterials thus represent one of the best defined and controlled classes of naoscale building blocks, which correspondingly have enabled a wide-range of devises and intergration strategies to be pursed in a rational manner. This conference is about the forefront research and inventions in rational synthesis, structure and property characterizations, device fabrication, system assembly and novel applications of 1D nanomaterials in nanoelectronics, nano-optoelectronics, nanophotonics, biomedical sciences, sensors, nano-enabled energy technology (solar cell, thermoelectric, piezoelectric nanogenerator, energy storage), nanopiezotronics, and environmental sciences.
