Thick film technology powders

This prevents water penetration and only the exterior of the electrode is exposed to electrolytes. When used with 30 nm sized carbon black powder, the conductive area of the electrode in contact with the electrolyte consists of less than 1 % of the geometric cross-sectional area of the electrode. This has been compared with an ensemble of microelectrodes. These CCEs showed an improvement of up to three orders of magnitude in terms of Faradaic signal-to-noise compared with glassy carbon electrodes [218]. In addition, the sol gel method of preparation affords a variety of structural configurations and it has been shown that CCEs can be produced by thick film and ink jet technology, which allows for their mass production [219]. 

It was found that, for sensor design, both thin-fihn (Benson et al. 1998) and thick-film (Whitten et al. 2006 Mohajeri et al. 2009) technologies can be nsed. In the latter case, various light-colored metal oxides in the form of fine powders (0.01-100 pm) can be used as a support for the POC of W and Mo,... 

The great interest in sol-gel chemistry arises not only because of the simplicity of the procedure required to generate the material and the ease of doping, but also for several technological reasons. It is straightforward to obtain a sol gel material in a particular shape, be it in the form of powders, monoliths, thick/thin films or fibers. 

The synthesis and magnetic and electric characterization of finely dispersed powders and thin films of EuO Fe composite materials of various compositions were presented in [1,2]. Procedures for the fabrication of films with the different thicknesses by depositing them under conditions that meet the requirements of industrial technologies have been developed. In accordance with the X-ray data, the resulting composite films were always crystalline with the lattice parameter <2 = 0.5125-0.5140 nm, which is characteristic of EuO (B1 structure). The...
