In order to design and control the surface interaction between fine and nanoparticles in liquid and gas phases, we have been developing our original methods for characterization of molecular and nanometer-scale structure at interface, as well as the interaction between particles. In various application fields, since the control of adhesion and aggregation behaviors of nano and fine particles are one of the most important technologies, surface molecular structure design by organic ligands with different molecular structures for nanoparticles dispersion stability control in various organic solvents. For fine particle adhesion behavior control at high temperatures in energy and environmental systems is overviewed, the original characterization systems were developed to analyze the mechanisms of adhesion increase behaviors. New original method for preparation of model ash particles from pure silica and metal oxide particles was also developed by the addition of small amounts of elements, such as alkali metals and phosphates. Based on the analyzing results, the adhesion behavior of fine particles was controlled by the addition of various materials.
