Nanomechanical properties of dental resin-composites
Dental Materials, 2012To determine by nanoindentation the hardness and elastic modulus of resin-composites, including a series with systematically varied filler loading, plus other representative materials that fall into the categories of flowable, bulk-fill and conventional nano-hybrid types.Ten dental resin-composites: three flowable, three bulk-fill and four conventional

Nanomechanical properties of desmin intermediate filaments
Journal of Structural Biology, 2006Desmin intermediate filaments play important role in the mechanical integrity and elasticity of muscle cells. The mechanisms of how desmin contributes to cellular mechanics are little understood. Here, we explored the nanomechanics of desmin by manipulating individual filaments with atomic force microscopy.

Nanomechanical properties of vimentin intermediate filament dimers
Nanotechnology, 2009The cell's cytoskeleton, providing the cell with structure and shape, consists of a complex array of structural proteins, including microtubules, microfilaments and intermediate filaments. Intermediate filaments play a crucial role in mechanotransduction and in providing mechanical stability to cells, in particular under large deformation. By utilizing

Nanomechanical Properties of Globular Proteins: Lactate Oxidase
Langmuir, 2007We report on the study of the nanomechanical properties of a lactate oxidase (LOx) monolayer immobilized on gold substrates by atomic force microscopy techniques operating under buffer conditions. Topographical contact mode imaging evidenced the protein deformation under the applied tip load.

Nanomechanical Properties of Hydrated Carious Human Dentin
Journal of Dental Research, 2001Most restorative materials are bonded to caries-affected dentin that has altered structure. We tested the hypothesis that hydrated dentin of the transparent zone did not have increased hardness or elastic modulus. Nanoindentation by modified AFM was used to determine site-specific elastic modulus and hardness for components of hydrated dentin from 8 ...

Nanomechanical properties of commercial float glass
Journal of Non-Crystalline Solids, 2008The float process produces flat glass with a tin-rich surface due to contact with the molten metal bath. The incorporation of tin into the glass network is expected to modify the mechanical properties of the surface and the relative durability of the two sides of the material.

Nanomechanical Properties of Brittle Matter
2001The paper focuses on inelastic deformation of brittle materials, quasicrystals in particular. It is shown, that quasicrystals exhibit the normal indentation size effect (ISE) at room temperature, and the inverse one at elevated temperatures. Load-depth-curves exhibit distinct discontinuities, and unloading hysteresis was observed.

Nanomechanical properties of cellulose nanofibrils (CNF)
MRS Advances, 2015Cellulose is an abundant green polymer, which can be obtained in a variety of nanoscale structures broadly grouped as nano/microfibrils (CNF/MFC), bacterial celluloses (BC) or nano/microcrystals (CNC/CMC).

Nanomechanical properties of molecular deposition film
Journal of Wuhan University of Technology-Mater. Sci. Ed., 2005Two nanomechanical properties of the molecular deposition (MD) film deposited on the Au substrate were studied. The first is its nanotribological property investigated by an atomic force microscope, which indicates that the deposition of the MD film could reduce the frictional force.

Nanomechanical properties of polymer composite nanoclusters
Physical Mesomechanics, 2008The paper contains results of quantum mechanical and molecular dynamics simulation of the structure, energy characteristics, and nanomechanical properties of nanoclusters of a “polymer matrix - carbon filler” composite medium. Quantum mechanical simulation is carried out in the framework of the cluster approach, in the approximation of microscopic ...
