This study is concerned with the prediction of the effective thermal conductivity of nanocomposite thin films consisting of nanoparticles randomly distributed in a solid matrix. Crystalline sodium chloride with embedded monodisperse silver nanoparticles is investigated as a case study for thin films where phonons are the main heat carriers. To the best of our knowledge, the equation for phonon ...

Abstract The nanomaterials silver nanoparticles accompanied magnetite impurity (Ag–Fe 3 O 4 ) (AF) and cobalt nano ferrite/silver–magnetite (0.3 CoFe 2 /0.7Ag–Fe (CAF) nanocomposite were prepared by flash auto-combustion using urea as fuel. This is the first time preparing this new material. as-prepared characterized X-ray diffraction pattern, atomic force microscopy, Fourier transform infrared...

We used a sol–gel spin coating technique to synthesize nanocomposite thin films based on zinc oxide (ZnO) loaded with silver nanoparticles (NPs). tested these ZnO/Ag NPs photocatalysts, thickness of about 100 nm, for the photodegradation indigo carmine dye solution. The study focused effects Ag ZnO matrix as well impact their concentration photocatalytic performance nanocomposite. also highligh...

We performed a free radical polymerization of acrylamide in an aqueous solution by radio frequency-driven atmospheric pressure plasma jet. The was catalyzed simultaneous generation nanoparticles resulting percentage polymer yield increased factor 2–30 times. Polyacrylamide acted as capping agent for the silver nanoparticle formation yielding smaller while uncontrolled growth and massive particl...

A novel method of integration a silver-polydimethylsiloxane (PDMS) nanocomposite in microfluidic channel for the realization lab-on-a-chip is reported this work. By using silver nitrate aqueous precursor solution, nanostructures are formed on, and under surface PDMS, by situ reduction. The aggregates reduction have wide absorbance plasmon band UV–Visible range. Separated nano-islands, having na...
