Emission enhancement in dielectric nanocomposites

open access: yes, 2018
We consider emitting nanoparticles in dielectric nanocomposites with varying refractive index contrast and geometry. For that we develop a simple and universal method to calculate the emission enhancement in nanocomposites that employs solely the ...

Strong and osteoconductive poly(lactic acid) biocomposites by high-shear liquid dispersion of hydroxyapatite nanowhiskers

open access: yesNanocomposites, 2022
Controlled incorporation of bioactive hydroxyapatite (HA) into poly(lactic acid) (PLA) signifies a promising approach to design and development of biomedical-adaptive materials. Here we unravel a microwave-assisted biomineralization approach to synthesis

Polyethylene and Polypropylene Nanocomposites Based on Polymerically - Modified Clay Containing Alkylstyrene Units [PDF]

open access: yes, 2006
Sodium montmorillonite was modified with a new polymeric surfactant. The high molecular weight of the surfactant appears to have led to incomplete cation exchange of the clays, but did promote nanocomposite formation with polyethylene and polypropylene ...

A flexible one-pot route to metal/metal oxide nanocomposites [PDF]

open access: yes, 2010
We report a one-pot route to Au/CeO2 nanocomposites. A readily-available biopolymer, sodium alginate, is exploited for controlled formation and stabilisation of gold nanoparticles followed by in situ growth of a sponge-like network of CeO2 nanoparticles.

Silver nanoparticles–deposited sub-micro sized BaTiO3/PVDF composites: greatly increased enhanced constant and effectively suppressed dielectric loss

open access: yesNanocomposites, 2022
Silver (Ag) nanoparticles deposited sub–micro sized BaTiO3 particles (µBT) were fabricated as hybrid particles (Ag@µBT) to promote the dielectric response in a poly(vinylidene fluoride) (PVDF).

Fire retardancy of bis[2-(methacryloyloxy)ethyl] phosphate modified poly(methyl methacrylate) nanocomposites containing layered double hydroxide and montmorillonite [PDF]

open access: yes, 2009
Copolymer nanocomposites were prepared by suspension copolymerization of bis[2-(methacryloyloxy)ethyl] phosphate and methyl methacrylate, together with bis(2-ethylhexyl) phosphate layered double hydroxide and a montmorillonite, Cloisite 93A.

Multiscale Modeling of Process‐Induced Defects in Fused Filament Fabrication‐Printed Materials

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a predictive multiscale modeling tool for defect analysis of fused filament fabricated‐printed materials and their performance prediction using a mechanistic data science‐based reduced‐order modeling approach. Process‐induced defects are inherent to additively manufactured parts and significantly influence the performance of printed

Polymer/Clay Nanocomposites [PDF]

open access: yes, 2011
Nowadays the enormous use of polymer materials is attributed to their extraordinary combination of properties, low weight and ease of processing. However for improvement of some properties such as thermal and mechanical stability, large numbers of additives were added to polymeric matrix and formed polymer matrix composite [1, 2].

Bayesian modelling approach to hydrogen permeation in fibre-reinforced polymer composites

open access: yesComposites Part C: Open Access
A Bayesian modelling approach is proposed to enable uncertainty quantification of hydrogen permeation in fibre-reinforced polymer composites. Specifically, the approach combines surrogate modelling via Gaussian Process (GP) regression, Bayesian ...
