improving barrier properties through the use of nanocomposites is an important area of research, especially for the food packaging industry. in this work, titanium dioxide (tio2 )/low density poly ethylene (ldpe) nanocomposites were synthesized as the oxygen barrier layers through the co-extrusion process. the oxygen permeability of the nanocomposite with 4% of tio2 decreased for about 16% comp...

B4C and its composites with TiB2 as second phase continues to be extensively used as the preferred ceramic material in military applications as armor systems for absorbing and dissipating kinetic energy from high velocity projectiles. It also exhibits a high melting point (2427 °C), and high neutron absorption cross section. Pressureless sintering of the B 4C-nanoTiB2 nanocomposite using small ...

The synthesis of polyaniline- Fe2O3 nanocomposite coating on aluminum Alloy 5052 (AA5052) surface has been investigated by using the galvanostatic method. The anticorrosion performance of polyaniline-Fe2O3 coating was investigated in 3.5% NaCl solution by the open- circuit potential (OCP), Tafel polarization technique and Electrochemical Impedance Spectroscopy (EIS). The corrosion rate of polya...

The interactions between a graphene sheet and an aluminium (111) layer in carbon-aluminium nanocomposite systems were investigated for various interfacial configurations using an ab initio simulation based on density functional theory. Dispersion relations and electron density distributions obtained for various interface registries suggest that the bond strength of the graphene/Al nanocomposite...

Electrically conductive polymer composites are suitable for use in the manufacture of antistatic products and components for electronic interconnects fuel cells and electromagnetic shielding. Selective laser sintering (SLS) was used to investigate the fabrication of electrically conductive nanocomposites of Nylon-12 filled with 4% by weight of carbon black. The effect of laser power and the sca...

the non-enzymatic glycation of low density lipoprotein (ldl) is a naturally occurring chemical modification of apolipoprotein b as a result of condensation between lysine residues and glucose. glycated ldl is poorly recognized by ldl receptors and initiates different processes that can be considered proatherogenic. thus, ldl glycation may contribute in the increased atherosclerotic risk of pati...

objective(s):resveratrol (res) is a polyphenol compound that has been shown a promising cardioprotective effect. however, some reports have yielded conflicting findings. herein, we investigated the anti-atherosclerotic effects of res in apolipoprotein e (apo e)-deficient mice on a high cholesterol diet. materials and methods: firstly, atherosclerosis was induced by feeding a high cholesterol di...

A functionalized graphene sheet-sulfur (FGSS) nanocomposite was synthesized as the cathode material for lithium-sulfur batteries. The structure has a layer of functionalized graphene sheets/stacks (FGS) and a layer of sulfur nanoparticles creating a three-dimensional sandwich-type architecture. This unique FGSS nanoscale layered composite has a high loading (70 wt%) of active material (S), a hi...
