Fig. 1. An integrated microflow reactor system consisting of four micromixers and four microtube reactors. Driven by remarkable improvements in our understanding of factors governing organic reactions, the role of organic synthesis has been expanded to various fields of science and technology, such as new materials and new medicinal agents. Because of rapid progress in such fields, demands for ...

The propagation of fractures during the drying of a colloidal silica suspension confined in a vertical microtube is investigated. During the drying process, the particle concentration increases until gel formation. In the gelled region, the tensile stresses increase and lead to the formation of two vertical perpendicular cracks propagating in the drying direction, dividing the tube into four eq...

The low specificity of anti-phosphoprotein antibodies is often a problem in immunoblotting analyses. We introduce a simple pretreatment procedure for cell lysates to give more specific detection of phosphoproteins in immunoblotting. Cellular phosphoproteins were preferentially trapped on Phos-tag agarose phosphate-affinity beads in a homemade spin-centrifuge microtube unit, and nonphosphorylate...
