anodic aluminum oxide (aao) fabricated by two step anodization technique, is used as a template to synthesize feco nanowire arrays by ac electrodeposition technique. response surface methodology (rsm) is applied to design the experiments, fit an empirical model and optimize the conditions to achieve the best magnetic properties. the magnetic properties, pore dimensions, composition and structur...

Dye-sensitized solar cells (DSSCs) utilize high surface area metal oxide sintered particle networks to absorb molecular dyes and transport injected charge carriers. While this sintered particle architecture allows liquid electrolyte DSSCs to achieve efficiencies up to 11%, slow charge transport through the semiconductor network limits the amount of modification that can be made to the electroly...

With increasing interest in the development of new composite systems for a variety of applications which require easily processible materials and adequate structural properties with high energy densities, we have pursued the chemical functionalization of oxide passivated aluminum nanoparticles (nAl) using three acrylic monomers, 3‐(trimethoxysilyl)propyl methacrylate (MPS), 2‐carboxyethyl acryl...

Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach t...

Nanofluid is a new class of heat transfer fluids engineered by dispersing metallic or non-metallic nanoparticles with a typical size of less than 100 nm in the conventional heat transfer fluids.This article aims to investigate the overall and convection heat transfer coefficient and Nusselt number of Al2O3-water nanofluid flowing in a horizontal double pipe heat exchanger under turbulent flow (...

In the present work, a facile approach to construct a nonvolatile resistive random access memory device based on the heterojunction of silver nanoparticles and aluminum oxide is reported. The device structure consisting of Aluminum-Aluminum oxide-Silver Nanoparticles-Aluminum is used to study the charge transport. The current-voltage measurements of this device clearly show the transition from ...

Nano-sized γ-Al2O3 was synthesized successfully by a simple method using Al2(SO4)3·18H2O as aluminium source and in the presence of polyethylene glycol (PEG 2000). FTIR spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to characterize the structure and morphology of synthesized powder. The results showed that PEG playe...

A simple theoretical model based on electric-field-assisted growth and dissolution of the barrier oxide has been proposed to understand the mechanisms for formation of a one-dimensional 1D anodic aluminum oxide AAO nanopore array. It is shown that formation of a one-dimensional horizontal nanopore array is the natural result of the self-adjusting effect of anodic oxidation. Because the electric...

Purpose: Acrylic dentures frequently fracture during service due totheir poor strength characteristics. The aim of this study was to evaluate the effects of adding 5%, 10% and 15% aluminum oxide powder on the flexural strength, surface hardness of a conventional heat-polymerized acrylic resin. Materials and methods: One of the commonly used conventional heat cure denture base resin (DPI) and hi...

A new material for microchannel plates (MCP) is proposed — anodic aluminum oxide. Microchannel plates made of this material may be much cheaper than with conventional lead glass MCP. Also a significantly smaller channel diameter (up to 70 nm) is easily achievable, which means better spatial resolution and the possibility to operate in strong magnetic fields. Methods and means are developed for ...
