Effect of sp2-phase nanostructure on field emission from amorphous carbons

Electron field emission from amorphous carbon is found to depend on the clustering of the sp phase. The size of the sp phase is varied by thermal annealing and it dominates the effect of other parameters, such as chemical composition, surface termination, sp content, or conductivity. The optimum size of the sp phase is determined by Raman spectroscopy and is of the order of 1 nm. The field emis...

Eliminating microleakage from the composite resin system.

Research indicates that microleakage is the major cause of composite restoration failure. Because the different physical properties of composite resin and tooth structure cause microleakage in composite tooth restorations, it is possible to eliminate microleakage by making composite's physical properties more similar to those of tooth structure. This article reviews the physical properties of c...
