Journal ArticleDOI
Nanoindentation mapping of the mechanical properties of human molar tooth enamel.
TL;DR: N nanoindentation is used to map out the properties of dental enamel over the axial cross-section of a maxillary second molar, finding that local variations in mechanical characteristics were correlated with changes in chemical content and microstructure across the entire depth and span of a sample.
Journal ArticleDOI
Mechanical deflection of cantilever microbeams: A new technique for testing the mechanical properties of thin films
TL;DR: In this paper, the Young's moduli and the yield strengths of thin-film materials that comprise the beams are determined using simple beam theory and the load-deflection data, the measured mechanical properties are compared to those obtained by indenting similar thin films supported by their substrate.
Journal ArticleDOI
Hardness and Young's modulus of human peritubular and intertubular dentine.
TL;DR: A specially modified atomic-force microscope was used to measure the hardness of fully hydrated peritubular and intertubular dentine at two locations within unerupted human third molars: within 1mm of the dentine enamel junction and within 1 mm of the pulp.
Journal ArticleDOI
Effect of intermixing on self-propagating exothermic reactions in Al/Ni nanolaminate foils
TL;DR: In this article, the authors measured the effect of intermixing thickness on the reaction velocities in multilayered Al/Ni nanolaminate foils and found that increasing the intermixed region from 2.4 to 18.3 nm reduced the reaction velocity for all of the foils.
Journal ArticleDOI
Joining of stainless-steel specimens with nanostructured Al/Ni foils
Jiaping Wang,Etienne Besnoin,Alan Duckham,Stephen John Spey,Michael Reiss,Omar M. Knio,Timothy P. Weihs +6 more
TL;DR: In this article, the authors describe the joining of stainless-steel specimens at room temperature using free-standing Al/Ni foils as local heat sources for melting AuSn solder layers.
