S.Z. cantilevers are made using a simple one-mask fabrication process with.characterization of a cantilever-type MEMS chemical sensor for detection of chemicals. MEMS has been with the advancement of cantilever-type sensors.sensor. The mechanical structure is a cantilever, having its own resonant frequency. MEMS cantilevers can be as thin as a few nanometers with lengths.Cantilever-based Sensor...

The outstading mechanical properties of bimodal ultrafine eutectic composites (BUECs) containing length scale hierarchy in eutectic structure were demonstrated by using AFM observation of surface topography with quantitative height measurements and were interpreted in light of the details of the deformation mechanisms by three different interface modes. It is possible to develop a novel strain ...

The effect of external constraints on Li diffusion in high-capacity Li-ion battery electrodes is investigated using a coupled finite deformation theory. It is found that thinfilm electrodes on rigid substrates experience much slower diffusion rates compared with free-standing films with the same material properties and geometric dimensions. More importantly, the study reveals that mechanical dr...

The resistance against rolling of a rigid cylinder on a flat viscous surface is investigated. We found that the rolling-friction coefficient reveals strongly non-linear dependence on the cylinder’s velocity. For low velocity the rolling-friction coefficient rises with velocity due to increasing deformation rate of the surface. For larger velocity, however, it decreases with velocity according t...

The deformation range, forces and frequency of the Magnetic Shape Memory Alloys (MSMAs) render them suitable for applications in electro-mechanical transducers, used to control pneumatic valves. A fast-operating electro-mechanical transducers can be designed, whose driving elements should not execute any motion, as they do in valves available to date, and which should get deformed instead. Util...

Common materials like metals appear to have unique and interesting properties when reduced to nanoscale. One example is that they become signifi cantly stronger, exhibiting strengths an order of magnitude higher than bulk. Understanding material strength at the appropriate scale is crucial in the design and reliable functioning of devices comprised of these materials. This article reviews recen...

Bisphosphonates are a common treatment to reduce osteoporotic fractures. This treatment induces osseous structural and compositional changes accompanied by positive effects on osteoblasts and osteocytes. Here, we test the hypothesis that restored osseous cell behavior, which resembles characteristics of younger, healthy cortical bone, leads to improved bone quality. Microarchitecture and mechan...

Design of deformation (thermo-mechanical) processes to achieve desired structural response will be addressed. Plastic deformation is assumed to be accommodated through crystallographic slip and reorientation of crystals. Conventional methodologies towards polycrystal plasticity use an aggregate of single crystals and this choice of the aggregate affects the response of the polycrystal. In order...

OBJECTIVE The purpose of this study was to compare the mechanical activity of the neck muscles during loaded arm lifting tasks in individuals with long-standing disability after anterior cervical decompression and fusion (ACDF) with that of healthy controls. METHODS Ten individuals (mean age, 60 years; SD, 7.1) who underwent ACDF (10-13 years previously) for cervical disc disease and 10 healt...
