BACKGROUND The goal of Japan's national "Healthy and Happy Family 21" campaign is to increase the nationwide breastfeeding rate for babies in the first month of life, which is currently below 50%, to a level of 60%. In this article, we summarize the breastfeeding rate for all of Japan's baby-friendly hospitals (BFHs) and extract their strengths in(More)
A mesoporous membrane composed of nanochannels with a uniform diameter has a potential use for precise size-exclusive separation of molecules. Here, we report a novel method to form a hybrid membrane composed of silica-surfactant nanocomposite and a porous alumina membrane, by which size-selective transport of molecules across the membrane becomes possible.(More)
The apparent diffusion coefficients of tris(2,2'-bipyridyl)ruthenium ([Ru(bpy(3))](2+)) are estimated in silica-nanochannels which are assembled inside columnar alumina pores in an anodic alumina membrane, and are modified with alkylsilanes such as trimethylchlorosilane (C1), butyldimethylchlorosilane (C4), and dodecyldimethylchlorosilane (C12).
