Anelastic materials exhibit gradual full recovery of deformation once a load is removed, leading to dissipation of internal mechanical energy. As a consequence, anelastic materials are being investigated for mechanical damping applications. At the macroscopic scale, however, anelasticity is usually very small or negligible, especially in single-crystalline materials. Here, we show that single-c...

Zinc oxide [ZnO] thin films are deposited using a radiofrequency magnetron sputtering method under room temperature. Its crystalline quality, surface morphology, and composition purity are characterized by X-ray diffraction [XRD], atomic force microscopy [AFM], field-emission scanning electron microscopy [FE-SEM], and energy-dispersive X-ray spectroscopy [EDS]. XRD pattern of the ZnO thin film ...

Growing need of potent antibacterial agents has renewed a keen interest in the development of nanomaterials with antibacterial properties. The current work demonstrated the biosynthesis of zinc oxide nanoparticles (ZnO NPs) using aqueous leaf extract of Cardiospermum halicacabum and its bactericidal activity. The resultant biogenic metal oxide nanoparticles were analyzed by various characteriza...

here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (tea) and zinc acetate. the zno nano particles (nps) were formed and stabilized on the fabric surface by amine compound at 130 °c for 1 h. the synthesis of nano zno particles on the polyester fabric were confirmed by x-ray diffraction (xrd) pattern...

We report on the demonstration of the effectiveness of nanosecond laser annealing on optical properties of phosphorus ion (P)-implanted ZnO nanorods (NRs). Vertically-alligned ZnO NRs have been synthesized by nanoparticle-assisted pulsed laser deposition (NAPLD) on c-plane sapphire substrates. The pre-laser annealing was performed with the third harmonic (355 nm) of a Qwitched Nd:YAG laser at a...

Nano-crystalline ZnO particles were synthesized using alcoholic solutions of zinc acetate dihydrate through a colloidal process. Five types of capping agents: 3-aminopropyl trimethoxysilane (Am), tetraethyl orthosilicate (TEOS), mercaptosuccinic acid (Ms), 3-mercaptopropyl trimethoxysilane (Mp) and polyvinylpyrrolidone (Pv) were added at the first ZnO precipitation time (first PPT) to limit the...

UNLABELLED ZnO structures were deposited using a simple chemical bath deposition technique onto interdigitated electrodes fabricated by a conventional photolithography method on SiO2/Si substrates. The X-ray diffraction studies show that the ZnO samples have a hexagonal wurtzite crystalline structure. The scanning electron microscopy observations prove that the substrates are uniformly covered ...

Thin films of ZnO grown by sol-gel spin method using two different precursors viz. zinc nitrate and zinc acetate have been characterized for their crystalline nature and associated nanostructures. In some cases, the films consist of nanostructures in the form of nanocrystals and nanoneedles of dimensions in the range 15-60 nm. A comparison between the physical characterization and the nanostruc...
