Metallic copper nanoparticles are produced by spray pyrolysis of nitrates with an addition ethanol as cosolvent at 600 degrees C. Depending on the synthesis temperature, two interesting reaction pathways found: below 525 C, approximately 10% hollow Cu(2)O parent particles oxidized to CuO and then reduced Cu, but higher remaining takes a direct path accompanied morphology change. These regimes discussed in aspects phase-transformation kinetics, gas-phase solid-phase thermodynamics, force...
Water is an essential need for humans and consumed as drinking water after fulfilling the health requirement in Republic of Indonesia Minister Health Regulation No.492/Menkes/Per/IV/2010. Due to increasing demand, there are currently many refilled stores economical practical alternative way people. However, their safety still needs be tested laboratory. This condition impractical so that it a portable measuring instrument especially based on TDS sensor can measure total dissolved solids...
