HRTEM surface characterization of nanoscale solid-state materials

Surface structures of various nanoscale materials were studied in profile b y high-resolution transmission electron microscopy. These materials include carbon nanofibres containing polymerized carbon nanobells, boron carbonitr ide nanofibres with a cactus-like surface structure, carbon nanotubes with polymer coating, mesoporous molecular sieves with a paintbrush-like surface and some nanoparticle specimens with interesting surfaces. The formation m echanisms of the surface structures and the surface-related properties of t he materials also are discussed. Copyright (C) 2001 John Wiley & Sons, Ltd.
