Oxide Membrane

In this article, the anodic aluminum oxide (AAO) was prepared by two-step anodizing process in oxalic acid electrolyte. And a blue-emission of AAO itself attributed to the oxalate was observed. The AAO membrane with ordered nano-sized porous structure was an important membrane to produce nano-materials. And luminescent nano-particles embedded in AAO, such as ZnO in this article, possessed notably special performances which were due to the quantum size effect and the special environment provided by the nano-pores. Since AAO membranes possessed a unique structure, in this paper, an assumption about the application of the membrane in field emission display (FED) and electroluminescence (EL) was proposed.

Dielectrostriction is variation of dielectric properties of material with deformation. Linear relation between stresses and dielectric response, called stress-dielectric rule, closely resembles stress-optical rule. In addition, microscopic model predicts that dielectrostriction measurements are very effective for studying microstructure and size distribution of the suspended inclusions. In this paper, dielectrostriction effect is probed in silicone/aluminum oxide (Al2O3) suspensions having various distributions of micro- and nano-particles. A rosette of two planar capacitor sensors with mutually perpendicular electrodes is employed to detect the dielectrostriction responses and measure the strain-dielectric coefficients of suspensions during oscillatory shear flow. Experimental results confirm stress-dielectric rule for all suspensions; and show dielectrostriction response sensitive to particle distribution.

The adsorption behavior of acid orange-7 (AO-7) on aluminum oxide nanoparticles (ANP) generated by sol-gel method has been investigated to understand the physicochemical process involved and to explore the potential use of nano particles in textile effluent treatment and management. The results revealed that ANP can remove AO-7 dye up to 97.6 mg/g at 303 K. The adsorption process is found to be pH dependent and the optimum pH obtained is 2.0. The equilibrium was established in 1 h. Langmuir, Freundlich, and Temkin Isotherm models were applied on the system. Scanning electron microscopic analysis reveals eye-catching nanoporous morphology of the material. The results of FTIR spectroscopy reveal that the process is electrostatic complexation mechanism driven. XRD studies revealed nanocrystalline structure of ANP. BET surface area measurement suggests high pore volume and surface area of adsorbent. The kinetic measurements suggest pseudo-second-order kinetic processes. The thermodynamic measurements suggest that all processes are endothermic accompanied with negative ΔG° and positive ΔS°, ΔH°.

Bagging Method

The main aim of this article is to investigate the effect of inclusion of Aluminum oxide (Al₂O₃) nano particles at varied percentage of weights into the carbon fiber-reinforced (CFR) epoxy composites, and evaluating the Mechanical properties for flexure, Impact and Tensile strength. The Aluminum oxide (Al₂O₃) is included into various percentages starting from 1 to 5 wt% and spread homogeneously throughout the epoxy resin by ultrasonication process. The CFR- Al₂O₃ nano composites are prepared through layup technique and healed by vacuum bagging method. The mechanical properties such for flexure and ultimate tensile strength showed better properties due to the presence of Al₂O₃ nanoparticles, while response for CFRAl₂O₃ nano composites increased at 2 wt% addition of Al₂O₃ nano particles, and further reduction has been seen at 5wt% due to an greater static effect.
