The properties of poly(methylglutarimide) (PMGI) when used as an electron beam resist are investigated. The results show that PMGI, when developed with a weak developer, xylenes, shows contrast higher than 12, which is comparable to the contrast achieved in cold developed poly(methylmethacrylate), and approximately twice as high as the recently achieved PMGI contrast using other developers. Usi...

Superhydrophobic poly(methylmethacrylate) (PMMA) surface with nanostructure was prepared effectively via phase separation and selective solvent method. It is proposed that the cooperation of the nanostructure of PMMA surface and the surface group reorientation leads to the superhydrophobicity of PMMA surface. The superhydrophobic PMMA surface with nanostructure was characterized by scanning ele...

Stewart L, Pellegrini CA, Way LW. Cholangiooenous Reflux Pathways as Defined by Corrosion Casting and Scanning Electron Microscopy. The American Journal of Surgery 1988; 155: 23-8. Using corrosion casting and scanning electron microscopy of the rat biliary tree, we investigated the site and size of the pathways that allow bacteria to reflux from bile to blood. Nonobstructed rat biliary trees we...

Hyperostosis is the most common skull change associated with meningioma. Five hyperostosis cases of meningioma en plaque infiltrating the skull processed without previous decalcification of the bone tissue were investigated histologically and immunohistochemically with antibodies against somatostatin receptor 2A (SSR2A). Undecalcified bone biopsies embedded in methylmethacrylate and paraffin-em...

Abstract Objectives The present study was performed to determine if minocycline HCl could influence the behavior of deproteinized bovine bone mineral (DBBM) and bioactive glass (BG) particles when used as filler material for new generation in a guided augmentation model. Materials Methods Two occlusive titanium caps were placed on rat calvaria. One filled with BG particles, second DBBM both pre...
