RECENT PROGRESS OF NANO-MECHANICAL MAPPING
Chinese Journal of Polymer Science, 2009Nano-mechanical mapping by atomic force microscopy has been developed as an useful application to measure mechanical properties of soft materials at nanometer scale. To date, the Hertzian theory was used for analyzing force- distance curves as the simplest model among several contact mechanics between elastic bodies.

Micro- (and nano-) mechanical signal processors
SPIE Proceedings, 2010With quality factors (Q) often-exceeding 10,000, vibrating micromechanical resonators have emerged as leading candidates for on-chip versions of high-Q resonators used in wireless communications systems. However, as in the case for transistors, extending the frequency of MEMS resonators generally entails scaling of resonator dimensions ...

Intrinsic dissipation in a nano-mechanical resonator
Journal of Applied Physics, 2014We investigate the effect of size on intrinsic dissipation in nano-structures. We use molecular dynamics simulation and study dissipation under two different modes of deformation: stretching and bending mode. In the case of stretching deformation (with uniform strain field), dissipation takes place due to Akhiezer mechanism. For bending deformation, in

The Effect of Cross-Linking on Nano-Mechanical Properties of Polyamide
Key Engineering Materials, 2016Radiation crosslinking of polyamidu 6 (PA 6) is a well-recognized modification of improving basic material characteristics. Radiation, which penetrated through specimens and reacted with the cross-linking agent, gradually formed cross-linking (3D net), first in the surface layer and then in the total volume, which resulted in considerable changes in ...

Nano-mechanical Properties of Fluoride-treated Enamel Surfaces
Journal of Dental Research, 2008Calcium-fluoride-like deposits play a key role in caries prevention by topical fluoride. Previous microhardness analyses have introduced errors due to a substrate effect, and thereby could not substantiate the early loss of these deposits. To address this question, we applied Atomic Force Microscopy (AFM) and a nano-indentation technique in this study ...

Comparative study on nano-mechanics and thermodynamics of fish otoliths
Materials Science and Engineering: C, 2013Fish otolith is a kind of typical natural biomineral, which is composed of calcium carbonate and organic matrix. In fresh water carp otolith, the inorganic phase of lapillus is pure aragonite, and for asteriscus it is pure vaterite. In this research, the phase composition, phase transformation, mechanical property and solubility of lapillus and ...

Quantum behaviour in nano-mechanical systems
2010The emerging field of nano-electro-mechanical systems (NEMS), in which the single mode of a nanomechanical oscillator plays the role of an active device, is receiving much attention due to its technological importance. The characteristic component that gives the name to these devices is an oscillator of nanometer size coupled to the electrons on the ...

Micro/Nano Mechanics of Contact of Solids
2011Solid objects in contact with each other are omnipresent in technological applications. Due to the presence of unavoidable surface irregularities in the form of asperities, the contact is established at many locations in the form of islands, whose sizes vary from atomic scale to the size of the contacting objects.
