Nanomechanical Properties of Endodontically Treated Teeth
Journal of Endodontics, 2011Although it is apparent that teeth become more susceptible to fracture after root canal treatment, the contributing factors for this are not completely established. The purpose of this study was to determine whether there are changes in nanomechanical properties of dentin in root canal-treated teeth compared with non-root canal-treated control teeth ...

Understanding the crystallographic and nanomechanical properties of bryozoans
Journal of Structural Biology, 2022This study examines how microscale differences in skeletal ultrastructure affect the crystallographic and nanomechanical properties of two related bryozoan species: (i) Hornera currieae, which is found at relatively quiescent depths of c. 1000 m, and (ii) Hornera robusta, which lives at depths of 50-400 m where it is exposed to currents and storm waves.

Nanomechanical properties of hardened 60NiTi
Materials Science and Engineering: A, 2021Abstract The nanomechanical properties of hardened 60NiTi were studied using nanoindentation. The hardened 60NiTi consists of two regions: the NiTi + Ni4Ti3 region, which is composed of a B2 NiTi matrix and nanoscale Ni4Ti3 precipitates, and the globular Ni3Ti precipitates. Blind nanoindentation was first performed on 60NiTi using a diamond Berkovich

Nanomechanical properties of nacre
Journal of Materials Research, 2006Nacre, the inner iridescent layer of seashells is a model biomimetic system composed of 95% of inorganic (aragonite) phase and 5% of organic phase. Nacre exhibits an interlocked layered “brick and mortar” structure where the bricks are made up of aragonitic calcium carbonate and mortar is an organic phase.

Nanomechanical properties of single amyloid fibrils
Journal of Physics: Condensed Matter, 2012Amyloid fibrils are traditionally associated with neurodegenerative diseases like Alzheimer's disease, Parkinson's disease or Creutzfeldt-Jakob disease. However, the ability to form amyloid fibrils appears to be a more generic property of proteins. While disease-related, or pathological, amyloid fibrils are relevant for understanding the pathology and

Nanomechanical Property Analysis of Silica Aerogel
Volume 1: 15th International Conference on Advanced Vehicle Technologies; 10th International Conference on Design Education; 7th International Conference on Micro- and Nanosystems, 2013Aerogels (AGs) are open-cell nanofoams. AGs are lightweight and possess high thermal and acoustic insulation properties. Due to their ∼ 90% porosity, AGs are very brittle and fragile, which inhibits its use for load-bearing applications. For this reason an area of open research is the study and improvement of the mechanical properties of aerogels ...

Nanomechanical Properties of Vimentin Intermediate Filament
Advanced Materials Research, 2012Vimentin intermediate filament (IF) is one of the major proteins which built the cytoskeleton network alongside with the microtubule and actin filament. Though it was known that the vimentin IF network plays an important role in the mechanical behaviours of cells, it is surprised that its mechanical behaviours are not fully understood to date.

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
