A Novel Microshear Test to Measure Dental Adhesion

February 1, 2001
Author(s)
Joseph M. Antonucci, Walter G. McDonough, Gary E. Schumacher, Y Shimada
A key factor in determining the strength and durability of polymeric dental restorative composites, sealants and adhesives is the quality of their interfaces/interphases. Bulk mechanical strength tests such as tensile, transverse and shear tests are

Hydrogen in nonstoichiometric cubic titanium monoxides: X-ray and neutron diffraction, neutron vibrational spectroscopy and NMR studies

Self-Assembled Monolayers: Effect of Chain Length on Nanofriction

September 6, 2006
Author(s)
S Hsieh, S Sambasivan, J V. Sengers, Stephen M. Hsu
We measured the interfacial friction of a series of alkylsilanes with chain lengths from C5 to C30 on silicon (100) surfaces using an Atomic Force Microscope (AFM). The dependence of the friction on chain length exhibits an optimum curvature with C12
