The flexoelectric effect is a coupling of polarization and strain gradient, which exists in a wide variety of materials and may lead to strong size-dependent properties at the nanoscale. Based on an extension to the classical beam model, this paper investigates the electromechanical coupling response of piezoelectric nanobeams with different electrical boundary conditions including the effect o...

The fabrication and understanding of the fundamental properties of well-defined one-dimensional structures are critical towards the development of nanostructures, nanomaterials, and developing nanotechnology. One-dimensional nanostructures can address basic issues about size and dimensionality in applications such as photonics [1,2], nanoelectronics [3,4], nanostructured materials [5,6], and ma...

We report on the experimental observation of curved plasmonic beam, a hook (PH), for surface plasmon-polariton (SPP) waves. The SPP PH effect could be obtained with cuboid particle broken shape symmetry fabricated relatively simple routine. This has pronounced difference fabrication structure generation Airy SPPs, which require complex techniques to compensate wave vector mismatch. confirmed ex...

In this paper, the shape transferability of using nanoscale multi-tip diamond tools in the diamond turning for scale-up manufacturing of nanostructures has been demonstrated. Atomistic multi-tip diamond tool models were built with different tool geometries in terms of the difference in the tip cross-sectional shape, tip angle, and the feature of tool tip configuration, to determine their effect...

Nucleation and Growth of Bubbles In article number 2103301, Yongming Hu, Chee Leung Mak, Linfeng Fei, co-workers present the nucleation growth mechanisms bubbles extracted in TEM by monitoring decomposition a solid precursor. Under electron-beam irradiation, 2D Ni(OH)2 flake emits gaseous species within matrix, leading to nanoscale bubbling processes via three-step pathway.

The classical Euler–Bernoulli beam model and Kirchhoff plate are very useful on the macroscopic scale. In context of Eringen’s nonlocal elasticity theory, this article aims to develop criteria applicability nanoscale models based Timoshenko Mindlin via wave propagation theory. corresponding governing differential equations for derived by Hamilton’s principle, dispersion then obtained. By applyi...

Abstract Gas storage and recovery processes in shales critically depend on nano-scale porosity chemical composition, but information about the nanoscale pore geometry connectivity of kerogen, insoluble organic shale matter, is largely unavailable. Using adsorption microcalorimetry, we show that once strong sites within network are taken, gas even at very low pressure governed by width rather th...
