Indium phosphide (InP) semiconductor nanoparticles were obtained by laser ablation of a crystalline wafer in water. The transmission electron microscopy micrographs of the nanoparticles show that their size is in the range of 100 nm. In the Raman spe

Self-assembled monolayers of several alkanethiol molecules, with varying chain length and terminal groups, were investigated using x-ray photoelectron spectroscopy (XPS). The chain lengths varied from 10 to 15 methylene units, and the terminal group

To date, the dentin/adhesive (d/a) bond has primarily been studied by morphologic analysis in conjunction with bond strength measurement. Although these analyses have enhanced our understanding, numerous questions about the chemistry have not been an

In tissues that closely approximate bone, sufficient heat may be transferred to the bone during laser surgery to cause damage and/or necrosis. To date, there have been few studies examining the temperatures elicited at the bone surface as a result of

The clinical success of dental composites depends critically upon the adhesive bond that secures it to the tooth. Previous efforts to characterize the adhesive/dentin interface have generally required sample preparation that alters or damages the int

The degree of adhesive penetration into dentin has been studied through micro-Raman spectroscopic examination of the dentin/adhesive interface. In contrast to previous studies, for the specimen examined in this work the adhesive penetrates less than
