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 ...

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 ...

Design and simulation of nano-mechanical resonator for virus detection
2014 IEEE Sensors Applications Symposium (SAS), 2014In the present study, nano mechanical resonator is used to detect different viruses. Biosensors have been designed using single walled Boron Nitrite Nanotube (SWBNNT) as a sensing material in terms of nanowire and micro cantilever. Here we have considered two approaches for sensing the biomolecules.

Nano-structure and nano-mechanical properties of human teeth
2011 6th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2011In this study, we investigate the nanostructure and nano-mechanical properties of human teeth. A nano-indenter is adopted to acquire the nano-mechanical properties of teeth, while a focused ion beam system (FIB) is used to prepare high quality transmission electron microscopy specimen.

Nano-mechanical behaviour of lithium metasilicate glass–ceramic
Journal of the Mechanical Behavior of Biomedical Materials, 2015This paper reports the first study on the mechanical behavior of lithium metasilicate glass-ceramic using nanoindentation and in situ scanning probe imaging techniques. Indentation contact hardness, Hc, and Young's modulus, E, were measured at 10 mN peak load and 0.1-2 mN/s loading rates to understand the loading rate effect on its properties ...

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 ...

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.
