45S5 bioactive glass (BG) is a bioactive material known to bond to bone in vivo through a surface calcium phosphate (Ca-P) layer. The goal of this study was to address the importance of BG surface charge in the bioactive response by examining the relationship between charge variations and the formation of the surface Ca-P layer. The zeta potential of BG in an electrolyte solution (TE) was measu...
Ab initio molecular dynamics simulations have been performed on the water/Pt interface. When the surface is neutral, water is found to form a contact layer directing its O atom toward the surface, i.e., O-down configuration. When the surface is negatively biased, the contact layer shows a significant structural change. The O-down configuration is converted mostly to the H-down configuration. As...
The peripheral surface of a fertilized, uncleaved egg is subdivided through cleavage and is allotted to constituent cells. This is called the primary surface. In an early morula a constituent cell has two kinds of surfaces: the primary surface, and the secondary surface, which does not participate in forming the periphery of the embryo. Electron-microscopic observations showed structural differ...
