in this work, a new aluminum matrix nanocomposite reinforced with beta-magnesium aluminide nanoparticles was produced by powder metallurgy technique. the prealloyed al-40 wt.% mg intermetallic ingot was milled for 100 hours to synthesize β-al3mg2 nanoparticles with the average size of 25 nm. different amounts of nanoparticles were added to al matrix powder and the mixture was then milled for 10...
Polysaccharide nanocomposites have become increasingly important materials over the past decade. Polysaccharides offer a green alternative to synthetic polymers in the preparation of soft nanomaterials. They have also been used in composites with hard nanomaterials, such as metal nanoparticles and carbon-based nanomaterials. This mini review describes methods for polysaccharide nanocomposite pr...
In the first part of this paper, stability in the open air and ageing of plasma polymer films is concisely reviewed. Nanocomposite films metal/plasma polymer are shortly discussed. Their ageing is considered. Future work on more complex composites such as Sn or SnO2 /plasma polymer films is outlined.
We have studied the surface-smoothing effect of an ultrathin germanium (Ge) layer on silver (Ag)-silica (SiO2) nanocomposite films for superlensing applications. Our experimental results indicate that inserting a thin Ge layer below the silver-silica composite films can reduce the final surface root-mean-squared (RMS) roughness to under 1 nm. Additionally, the metal nanostructure plays a role i...
One-dimensional carbon nanotubes (CNT), which are mechanically strong and flexible, enhance strength of the host metal matrix. However, the reduction of ductility is often a serious drawback. Here, we report significantly enhanced plastic flow strength, while preventing tensile ductility reduction, by uniformly dispersing CNTs inAlmatrix. Nanoscale plasticity and rupturing processes near CNTs w...
MoS(2)@CMK-3 nanocomposite consisting of confined nanosized MoS(2) in CMK-3 carbon matrix exhibits much improved cycling performance and rate capability due to the enlarged interlayer distance and favorable conductivity.
the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...
Boron carbide is known as a hard material; it possesses unique complex of physical-mechanical properties and has diverse applications in industries. An expansion its field uses stems from the creation boron matrix nanocomposite materials. In view this perspective, an effective liquid-charge synthesizing method for their components nanopowder form been proposed. This paper provides focused revie...
The Ag-Ge-S system is among the best-performing active materials for a new class of high-performance electronic memory known as programmable metallization cells.[1,2] Memory switching in a programmable metallization cell relies on the electrochemical formation and dissolution of an electronically conducting filament within a solid electrolyte. In the Ag-Ge-S system, this electrochemical process...
Hydroxyapatite/silver nanocomposites have been designed and synthesized as an engineering material for biomedical applications. The hydroxyapatite matrix was synthesized by a sol-gel method and, subsequently, the Ag nanoparticles were deposited by heterogeneous precipitation followed by two different reduction routes: thermal or chemical. Both sets were studied and compared and, in all cases, t...
