The results on measuring the I-V characteristics of metal-semiconductor transition within Ti(200nm)|Si@O@Al(179nm)|Ti(203nm) test structure are presented. basis Si@O@Al nanocomposite is a solid solution Al in amorphous silicon a-Si(Al). I–V has form characteristic reverse-biased ohmic contact between metal and p-type semiconductor, which implies that a-Si(Al) substitutional solution. It shown f...

A new procedure for identifying the mechanical behavior of individual phases within a bi-material (matrix-particles) is presented. The case AlSi10Mg (large globularized Si-rich particles surrounded by an α-Al phase) processed additive manufacturing and post-treated taken as typical example. Grids nano-indentation tests are performed at different locations on nanocomposite using Berkovich indent...

Abstract Aluminum oxide (Al 2 O 3 ) nanoparticles are capable of improving the material characteristics if reinforced to soft and low strength material. The major limitation in utilization Al alloy 6061 medium heavy stress applications such as automobile, defense, transportations, aerospace is hardness strength. In order overcome deficiency Al6061, nano-Al Al6061 matrix nanocomposite (AMNC) was...

In this work, the multi-walled carbon nanotubes (MWCNTs) were purified with an acid treatment and subsequently dispersed using ultrasound a nonionic surfactant solution of ethoxylated lauric alcohol 7 moles ethylene oxide (E7E). Then, (CNTs) used as reinforcement phase (0.4 wt.% 0.8 wt.%) in Al- 10Mg alloy. The high-energy ball milling was employed for nanocomposites processing, resulting powde...

A three-dimensional micromechanics-based analytical model is developed to study thermo-mechanical properties of polymer composites reinforced with randomly distributed silica nanoparticles. Two important factors in nanocomposites modeling using micromechanical models are nanoparticle arrangement in matrix and interphase effects. In order to study these cases, representative volume element (RVE)...

The effect of milling time on the morphology, microstructure, physical and mechanical properties of pure Al-5 wt % Al₂O₃ (Al-5Al₂O₃) has been investigated. Al-5Al₂O₃ nanocomposites were fabricated using ball milling in a powder metallurgy route. The increase in the milling time resulted in the homogenous dispersion of 5 wt % Al₂O₃ nanoparticles, the reduction of particle clustering, and the red...

Polymer-clay nanocomposite coatings have attracted much attention because of impressive enhancements of coating properties. In this research, both commercially available and isophoronediamine-modified montmorillonite clays were used to obtain epoxy-clay nanocomposite coatings. These nanocomposite materials with different clay loadings in the form of coatings were applied to cold-rolled steel (C...

nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. antimicrobial nanocomposite ldpe films containing zno nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-zno pulse 10% polyethylene grafted maleic anhydride (pe-g-ma), w/w pure ldpe), were p...

in this work at the first step calcium hydroxide nano-particles were synthesized via sono-chemical method at room temperature. at the second step aminated multi-walled carbon nano-tubes was prepared via chemical modification of surfaces of cnt. finally modified-mwcnt and ca(oh)2 were added to paraloid matrix by aid of ultrasonic irradiation. paraloid-modified-mwcnt-ca(oh)2 nanocomposite was use...

Nanostructured composite sorbent of Mg/Al-aminobenzoate layered double hydroxide was prepared by coprecipitation method. The particle size of the nanocomposite was found to be 10-20 nm. Sorption performance of the prepared material was studied for removal of cobalt ion from aqueous solution. The percent uptake of cobalt ion was found to be 96.1%. The loading capacity of Mg/Alaminobenzoate compo...
