We present a dip-coatable, high-capacitance ion gel dielectric for scalable fabrication of three-dimensional (3D) electrowetting-on-dielectric (EWOD) devices such as an n × n liquid prism array. Due to the formation of a nanometer-thick electric double layer (EDL) capacitor, an ion gel dielectric offers two to three orders higher specific capacitance (c ≈ 10 μF/cm²) than that of conventional di...

A nanolayer of composite and Rhodococcus erythropolis biocatalyst was studied for the first time for desulfurization of dibenzothiophene as a model sulfur compound and its performance was compared with that of composite and R. erythropolis alone. The nanolayer of composite was synthesized by sol-gel method from ferrous oxalate and zinc oxalate precursors coated on glass by spin coating techniqu...

Recent advances in the use of plasmonic metamaterials to improve absorption of light in thin-film solar photovoltaic devices has created a demand for a scalable method of patterning large areas with metal nanostructures deposited in an ordered array. This article describes two methods of fabricating ordered 2D nanosphere colloidal films: spin coating and interface coating. The two methods are c...

The fabrication of multi-level SU-8 microstructures using multiple coating and exposure steps and a single developing step has been achieved for up to six layers of SU-8. Alternating layers of SU-8 2010 (thin) and SU-8 2100 (thick) photoresist films were spin coated, followed by soft-bake, ultraviolet (UV) exposure and post-exposure bake steps. The multiple SU-8 layers were simultaneously devel...

This experiment attempted to create an organic solar cell using a simple spin coating technique. This was to be done using ZnPc and C 60 dissolved in chloroform. However no working solar cell was made. This was probably due to problems with dissolving the solutes in chloroform which led to aggregation and incomplete coverage of the slides during the spinning process. This problem with spinning ...

Metal nanowire networks are promising alternatives for transparent conducting layers in flexible electronics. However, the inverse relationship between transparency and conductivity limits their viability in many critical applications. In this work, we demonstrate a direct-write refining technique in which a solution-processed nanowire network, deposited by spin coating, is exposed to monochrom...

in this study, tio2 and zno nanofilms were prepared by sol-gel spin-coating method. nanofilms were characterized by x-ray diffraction (xrd), energy dispersive analysis of      x-ray (edx), scanning electron microscopy (sem) and field emission scanning electron microscopy (fe-esm). structural and morphological properties of nanofilms were investigated. the average crystalline size of tio2 and zn...

SODIUM CHLORATE IS MAINLY USED for production of chlorine dioxide (a pulp bleaching agent). Sodium chlorate is produced by an electrochemical process where chloride ions (from sodium chloride dissolved in water) are oxidized to chlorine on the anodes and hydrogen is evolved on the cathodes. The anode of this process consists of a metal plate coated with a catalytically active metal oxide film. ...
