The aim of this symposium is to provide to the materials science community a unique forum to discuss current research activities focused on undoped, doped and surface functionalized one-dimensional (1D) nanostructures (including tubes, wires, rods, saws and belts), whose lateral dimensions fall within the 1-100 nm range. The functional quality of 1D nanostructures is based on their structure-property relationship, whose determination begins at an atomic level, and their ultimate utilization in novel smart devices and biological platforms.
Over the past few years, there has been increased interest in 1D nanostructures due to their fascinating material properties and prospective innovative technological applications. For instance, based on their unique geometric characteristics, 1D semiconductor, metal and carbon nanostructures, play a pivotal role as next-generation building blocks for electronic and photoelectronic devices, for chemical/biological/optical sensors, and for energy harvesting, storage, and conversion. 1D nanostructures can be readily designed to deterministically incorporate heterojunctions that promote charge separation and directional transport as well as to selectively position different catalysts. Recent advances in achieving high-quality 1D nanostructures with control over size and size dispersity, composition, structure, phase, and physical properties have further driven progress toward applications.
Regarding the 1D nanostructures organization issue, the capability of nanoscopic materials to be self-organized into large-scale assembly structures that exhibit unique collective properties has recently opened up new and exciting opportunities in the field of nanotechnology. The integration of 1D nanostructures into 2D and 3D higher-order architectures with rational design and biomimetic principles is a feasible and highly efficient strategy to obtain enhanced optical, electrical, and mechanical properties for photocatalytic solar energy conversion applications. Growth and integration of 1D nanostructures into 3D spatially high-dimensional architectures, bridges the gap between the nano- and the micro- and macro-scales, and forms the basis for an assembly of 1D materials into higher hierarchy domains.
In this regard, this symposium will cover: i) the existing synthetic approaches (top/down or bottom/up) that have been demonstrated for generating various types of 1D nanostructures; ii) fundamental properties; iii) the novel and intriguing phenomena associated with 1D nanostructures; iv) the experimental issues related to the assembly of 1D nanostructures into complex architectures; v) the potential of 1D nanostructures as functional components in device fabrication, biological probing, and nanomedicine; and vi) the projected impact of 1D nanostructures on the environment and health.
