Monodispersed colloidal silica (CS91, diameter = 110 nm) suspensions were dried on temperature-controlled (10 to 50 C) cover glasses. The volume fraction (phi) of the spheres in suspensions was 0.001 to 0.04. It is interesting that circular pattern with a ring structure at the outside edge was formed, both at 0 G and 1 G. This implies that Marangoni convection plays an important role for the pattern formation at 0 G. The patterns formed were analyzed by confocal laser scanning microscope. The width of the ring formed at 0 G was broader than that at 1 G. It is considered that particle transport from the pattern center to edge at 0 G was small due to the lack of convection by gravity., 資料番号: AA0063349063}, pages = {234--237}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {コロイド分散系の乾燥散逸構造発現に対する微小重力効果}, year = {2007} }
