Nanoparticles have a size of 1nm-100nm in any one the three dimensions. Smaller nanoparticles different physical, chemical and biological properties than atoms molecules. Metals, non-oxide ceramic materials, metal oxides, silicates, polymers, organic biomolecular components can be used to create material nanoparticles. come various shapes, like spheres, platelets, cylinders, tubes. Green synthe...

The ceramics industry, resulting from developments of modern compounds, is a segment great influence in worldwide sustainability. Artisanal ceramic factories based on wood combustion have significant risks for the creation and discharge atmosphere nanoparticles (NPs) ultra-fine particles (UFPs). At present, there insufficient recognition engineered-NPs health. Real improvements are indispensabl...

Nowadays, the development of new materials that can be used to treat, repair, diagnose, replace, or restore a function human body represents one key research topics for worldwide scientists and medical industries [...]

We made a semiquantitative study of the comparative histology of pseudomembranes from 12 loose cemented ceramic-ceramic and 18 metal-polyethylene total hip replacements. We found no significant difference in cellular reaction between the two groups, but there was a major difference in the origin of the particulate debris. In the metal-polyethylene group, polyethylene of articular origin was pre...

STATEMENT OF PROBLEM During the insertion appointment, the practitioner is often faced with the need to adjust ceramic surfaces to fit a restoration to the adjacent or opposing dentition and soft tissues. PURPOSE The purpose of this study was to assess the ceramic surface smoothness achieved with various commercially available ceramic polishing kits on different commonly used ceramic systems....
