In this paper, axisymmetric free vibration analysis of a circular Nano-plate having variable thickness was studied. The variation in thickness of plate was considered as a linearly in radial direction. Nonlocal elasticity theory was utilized to take into account size-dependent effects. Ritz functions was utilized to obtain the frequency equations for simply supported and clamped boundary. To ve...

Enhancing volatile organic compound (VOC) sensing performance sensors in terms response is vital for their practical application. Decoration noble metals onto nanostructures an effective approach improving characteristics. Herein, hydrothermally synthesized coral-like n...

Graphene-ZnO nanohybrid thin films were prepared by spray pyrolysis technique at 350 °C. Different graphene nanoplate concentrations of 0.1, 0.2, 0.3, 0.4, and 0.5 wt.% used to deposit on quartz substrates. The Structural optical properties the have been investigated. X-ray diffraction XRD results show that a hexagonal wurtzite polycrystalline structure no secondary phases observed. structural ...

Nanoplates have been extensively utilized in the recent years for applications nanoengineering as sensors and actuators. Due to their operative nanoscale, mechanical behavior of such structures might also be influenced by inter-atomic material interactions. For these reasons, nonlocal models are usually introduced studying behavior. Sensor technology plate should formulated with coupled mechani...

A simple route to fabricate a surface layer comprising Fe3O4 nanoplates on carbon steel has been successfully demonstrated using etching treatment followed by annealing in oxygen atmosphere. Different sizes of the (3 1 1) exposed can be fabricated varying temperature. Density Function Theory (DFT) calculation proved that energy was lowest among all facets, which make it most stable. The superhy...

Over the last decade, field-effect transistors (FETs) with nanoscale dimensions have emerged as possible label-free biological and chemical sensors capable of highly sensitive detection of various entities and processes. While significant progress has been made towards improving their sensitivity, much is yet to be explored in the study of various critical parameters, such as the choice of a se...
