The nano-mechanical morphology of shale
Mechanics of Materials, 2008Abstract Shale, the sealing formations in most hydrocarbon reservoirs, is made of highly compacted clay particles of sub-micrometer size, nanometric porosity and different mineralogy. In this paper, we propose and validate a technique to identify the nano-mechanical morphology of such a nanocomposite material.

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.

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

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 ...

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 ...

Chemotherapeutic resistance: a nano-mechanical point of view
Biological Chemistry, 2018Abstract Chemotherapeutic resistance is one of the main obstacles for cancer remission. To understand how cancer cells acquire chemotherapeutic resistance, biochemical studies focusing on drug target alteration, altered cell proliferation, and reduced susceptibility to apoptosis were performed. Advances in nano-mechanobiology showed that

Nano-Mechanical Properties of Human Meniscal Surfaces
ASME 2011 Summer Bioengineering Conference, Parts A and B, 2011Osteoarthritis (OA) is a crippling disease in humans that deteriorates the articular cartilage (AC) and subchondral bone. Research has shown AC preservation is most important for halting the initiation of OA, in the human knee joint, and this defense is contingent on the structural integrity of the menisci [1, 2].
