Background: One area of nanoscience deals with nanoscopic interactions between nanostructured materials and biological systems. To elucidate the effects of the substrate surface morphology and viscoelasticity on cell proliferation, fractal analysis was performed on endothelial cells cultured on nanocomposite samples based on silicone rubber (SR) and various concentrations of organomodified nano...

Viscoelasticity is an essential property of bone related to fragility, which altered in aging and disease. Bone viscoelastic behavior attributed several mechanisms involving collagen mineral properties, porosities, hierarchical tissue organization. We aimed assess the relationships between cortical damping measured with Resonant Ultrasound Spectroscopy (RUS), microstructural compositional chara...

Abstract This work is devoted to studying a viscoelastic Kirchhoff-type equation with nonlinear boundary damping-source interactions in bounded domain. Under suitable assumptions on the kernel function g , density function, and M global existence general decay rate of solution are established. Moreover, we prove finite time blow-up result negative initial energy.

The theoretical sensitivity of Love wave and layer-guided shear horizontal acoustic plate mode ~SH-APM! sensors for viscoelastic guiding layers and general loading by viscoelastic materials is developed. A dispersion equation previously derived for a system of three rigidly coupled elastic mass layers is modified so that the second and third layers can be viscoelastic. The inclusion of viscoela...

The paper describes a method for reducing the positioning errors of a SCARA manipulator during the execution of a motion along a given trajectory; the stiffness and damping properties of the robot transmissions are considered in the mathematical model by introducing viscoelastic components between the actuators and the arms. By means of an optimization algorithm the motion laws of the actuators...

the preparation and characterization of the vinyltriethoxysilane-modified silica nanoparticles were investigated. also the surface tension of polystyrene, native (hydrophilic) silica and silane-modified (hydrophobic) silica were determined. two kinds of polystyrene/silica (treated and non-treated) nanocomposites were prepared with different filler loadings by solution method. their viscoelastic...
