Nanoparticle thin films have a vast range of applications in various fields due to their superior properties. There are a number of methods for nanoparticle thin film coatings, for example spray pyrolysis, electrodeposition, spin coating and sol-gel process. However, these methods are either a multistep synthesis or require the use of toxic substances. The sparking method is a onestep, simple...

In this research, we demonstrate a colorimetric plasmon sensor for the determination of mercury ions, which are toxic heavy metal ions. Colorimetric detection by the naked eye is certainly the most simple and convenient diagnostic method, especially when it does not require any complex optical or electrical systems. Colorimetric method using gold nanoparticles (AuNPs) is based on changes in...

Pure natural rubber (NR) has low durability and elasticity, which become a major bottleneck for practical use. To overcome the limitation, in general, the adding of carbon black and silica particles is applied$^{1,2}$, but carbon black has an effect of polymer cracking. Interestingly, the fullerene (C60) and carbon nanotube (CNT) can be used as rubber additive, resulting in the significant...

Lead halide perovskite solar cells (PVSCs) have been exhibiting high efficiency by using abundant materials and availability on flexible substrates with easy fabrication process. However, to fabricate the perovskite devices for large area are facing many problems such as surface coverage and quality of perovskite crystalline thin film. Here, we report the way to fabricate perovskite solar cell...

The presence of $\beta$-Cu(In,Ga)$_3$Se$_5$ phase on Cu-poor Cu(In,Ga)Se$_2$ thin film surface could play an important role in the efficiencies of Cu(In,Ga)Se$_2$ thin film solar cells. The $\beta$-Cu(In,Ga)$_3$Se$_5$ with various thicknesses were deposited after a completion of the three-stage co-evaporation process of Cu(In,Ga)Se$_2$ films. The optical absorption measurement is used to...

Stacks pattern of microspheres and nanoparticles can be deposited by layer-by-layer coating with several methods. In this work, we fabricated two monolayers of polystyrene microparticle by convective horizontal deposition. For initial layer, glass substrate was dragged with velocity of 25 $\mu$m/s, and applied horizontal vibration with frequency of 50 Hz in order to supply higher kinetic...

In this work, bacterial cellulose (BC) was biosynthesized by Glucanobacter xylinum bacteria. Fe$_{3}$O$_{4}$ nanoparticles under different concentrations were ex-situ impregnated into the BC structure. The BC pellicles in both never-dried and freeze-dried states were used as the templates to form BC-Fe$_{3}$O$_{4}$ nano-composites. Morphological studies of the samples indicated that the...
