The influence of the Ar/O2 gas ratio during radio frequency (RF) sputtering of the RuO2 sensing electrode on the pH sensing performance is investigated. The developed pH sensor consists in an RF sputtered ruthenium oxide thin-film sensing electrode, in conjunction with an electroplated Ag/AgCl reference electrode. The performance and characterization of the developed pH sensors in terms of sensitivity, response time, stability, reversibility, and hysteresis are investigated. Experimental results show that the pH sensor exhibits super-Nernstian slopes in the range of 64.33-73.83 mV/pH for Ar/O2 gas ratio between 10/0-7/3. In particular, the best pH sensing performance, in …

The aim of this study is to simplify the process of Discharge Thermal Energy Combined Desalination (DTECD) with Power System by integrating the two existing heat exchangers (condensers) into a new multi-stream one. This system is a heat recovery unit, which is used to cogenerate water and power. Two shell & tube condensers operate in a closed power cycle and a desalination system for cooling an ammonia mixture (70% wt.) as a working fluid and condensing a pure vapor respectively. Here, a multi-stream plate condenser is utilized instead of the two low exergy efficiency shell & tube condensers. The results …
