Abstract Free vibrations of the orthotropic micro/nanoplate with nonclassical shape are investigated. The considered model is based on nonlocal elasticity theory. developed method uses Ritz as well R-function theory for construction system coordinate functions. linear frequencies obtained a rectangular plate two cutouts opposite sides, while boundary conditions several types, including simply s...

Au@Cu2O cuboctahedron with gold triangular nanoplate core and Cu2O shell was synthesized by a chemical method. X-ray diffraction (XRD) and transmission electron microscopy (TEM) tests demonstrated that the as-synthesis samples were consisted of gold triangular nanoplate core and Cu2O shell, and both of them were in good crystallization. The effective size control of the particles could be reali...

Recent reports of the synthesis and assembly of faceted nanoplates with a wide range of shapes and composition motivates the possibility of a new class of two-dimensional materials with specific patterns targeted for a host of exciting properties. Yet, studies of how nanoplate shape controls their assembly - knowledge necessary for their inverse design from target structures - has been performe...

Cantilever based sensors are a promising tool for a very diverse spectrum of biological sensors. They have been used for the detection of proteins, DNA, antigens, bacteria viruses and many other biologically relevant targets. Although cantilever sensing has been described for over 20 years, there are still no viable commercial cantilever-based sensing products on the market. Several reasons can...

The atomic force microscope (AFM) has become an essential tool for imaging the surface topography of conductors and insulators on a microand nanoscale level [1]. In addition, AFM has also been powerful in nanomachining [2]. Cracks may occur in the AFM cantilever during the nanomachining experiments or in the fabrication of cantilever. The cantilever with cracks will affect its performance in us...

The atomic force microscope (AFM) has become an essential tool for the measurement of surface characteristics of diverse materials on a microand nanoscale level [1]. The resolution of measurements for the AFM cantilever is related to its vibration sensitivity. Many researchers have much interest in studying the resonant frequency and sensitivity analysis of AFM cantilevers [2 4]. Cracks may be ...

in this work, we report synthesis of silver nanoplates by a simple reduction process of silver nitrate in the presence of polyvinyl alcohol (pva) and n,n'-dimethyl formamide (dmf). the characterization of the samples were carried out using x-ray diffraction (xrd), transmission-electron microscopy (tem) and uv-vis spectroscopy. absorption spectra of the nanoplates in comparison with that of...

One of the bio-sensing mechanisms is mechanical. Rather than measuring shift in resonance frequency, we adopt to measure the change in spring constant due to adsorption, as one of the fundamental sensing mechanism. This study explains  determination of spring constant of a surface functionalized micro machined micro cantilever, which resonates in a trapezoidal cavity-on Silicon wafer, with the ...

A relationship based on the modified couple stress theory is developed to investigate the flexural sensitivity of an atomic force microscope (AFM) with assembled cantilever probe (ACP). This ACP comprises a horizontal cantilever, two vertical extensions and two tips located at the free ends of the extensions which form a caliper. An approximate solution to the flexural vibration problem is obta...
