Effect of length and radius of singlewall carbon nanotube on its mechanical properties

Alzubi F.G., Cosby R., Kuwait Institute for Scientific Research, KW

A first principles atomistic calculations and analysis of Young’s modulus for short arm chair carbon nanotubes with different lengths and radii is]]are reported. The atomic forces and total energies were computed for the carbon nanotubes [...]

Multiscale Biomechanical Modeling of the Human Eye

Karampelas I.H., Furlani E.P., Nunez A., Vizzeri G., State University of New York at Buffalo, US

The human eye is a complex organ consisting of multiple different tissues with varying mechanical properties and functionality. Hence, there are many aspects of the biomechanical behavior of the eye that are not understood. In [...]

Modeling Fluid Structure-Interactions for Biomechanic Analysis of the Human Eye

Furlani E.P., Nunez A., Vizzeri G., University at Buffalo (SUNY), US

The human eye is a highly complex organ that consists of multiple different tissues with different properties and functionality, as well as pressurized fluid compartments with limited flow. Owing to this complexity, there are many [...]

Change of the Electronic Conductivity of CNTs and Graphene Sheets Caused by a Three-dimensional Strain Field

Ohnishi M., Suzuki K., Miura H., Tohoku University, JP

Since the electronic structure of deformed carbon nanotubes (CNTs) varies widely depending on their chirality and deformation mode, CNTs have the potential to be high-quality strain sensors. The authors revealed the possibility of the high [...]

FinFET reliability issue analysis by forward gated-diode method

Liu Z., PKU HKUST Shenzhen Institution of IER., CN

The reliability issue of the FinFET device is studied in details in this paper by the forward gated-diode R-G current method. Extraction of the stress induced interface states and oxide traps of FINFET is performed [...]

The Design, Fabrication and Characterization of A Novel Miniature Silicon Microphone Diaphragm

Cui W., Miles R.N., Su Q., State University of New York at Binghamton, US

A novel miniature silicon microphone diaphragm is described that is highly robust when subjected to stresses that may arise during the fabrication process. Residual stress produces major challenges in the fabrication of MEMS devices. This [...]

Influence of Stress and Temperature on the Microstructure Stability of Nanocrystalline Materials

Rajgarhia R.K., Koh S-W., Spearot D., Saxena A., Selvam P., Tummala R., University of Arkansas, Fayetteville, US

Nanocrystalline materials have improved mechanical and electrical properties in comparison to their microcrystalline counterparts due to their reduced crystallite or grain size. Loss of these unique properties due to grain growth under the affect of [...]
