A complete study based on advanced atomic force microscopy electrical mode called scanning spreading resistance (SSRM) is carried out a series of samples zinc oxide (ZnO) nanowires grown by chemical bath deposition with different doping concentrations using gallium (Ga). The concentration free charge carriers determined through SSRM signal calibration specific molecular beam epitaxy-grown multi...

NiCu alloy nanowires arrays were embedded into the anodic aluminum oxide (AAO) template by ac-pulse electrodeposition. Different off-time were used in electrolyte with constant concentration of Ni and Cu and acidity of 3. The effect of deposition parameters on alloy contents was investigated by studying the microstructure and magnetic properties of as-deposited NiCu alloy nanowires. Atomic forc...

the aim of this research is preparation of sno2 nanowires by means of thermal chemical reaction vapor transport deposition (tcrvtd) method from sno powders. the morphology, chemical composition and microstructure properties of the nanowires are characterized using field emission scanning electron microscope (fe-sem), eds, and xrd. the xrd diffraction patterns reveal that the sno2 nanowires have...

using piezoelectric patches the stress concentration around a hole on a plate under tension is reduced and controlled. to attain the reduction in stress two placements for piezoelectric patches is investigated. the first location is top/bottom of the hole with compression induced strain and the second is left/right of the hole with tension induced strains to control the stress flow. the result ...

With piezoelectric small-volume composites gaining importance in smart device applications and nanoindentation being recognized as a versatile method for assessing the properties of layer materials, present study is focused on indentation response structures multi-layered composites. In particular, effects nature substrate surrounding nanocomposites, such nanoislands, nanowires, are investigate...

Abstract In this critical review, we call attention to a widespread problem related the vast disagreement in elastic moduli values reported by different authors for nanostructures made of same material. As particular example, focus on ZnO nanowires (NWs), which are among most intensively studied nanomaterials due their remarkable physical properties and promising applications. Since NWs possess...

Piezoelectric nanogenerators (PNGs) are capable of converting energy from various mechanical sources into electric energy and have many attractive features such as continuous operation, replenishment and low cost. However, many researchers still have studied novel material synthesis and interfacial controls to improve the power production from PNGs. In this study, we report the energy conversio...
