Sintering of Ni particles in the Ni-based anode is a major obstacle to the widespread use of solid oxide fuel cell because the sintering induces the degradation in the anode. The large amount of water vapor in the fuel is known to accelerate the degradation during the operation. However, the detailed accelerated sintering mechanism is unclear. In this study, to clear the accelerated sintering mechanism...
The process and action mechanism of the copper wastewater adsorption accomplished by ferric salt and cerous salt modified water granulated slag were studied in this paper. Results showed that under the conditions of room temperature of 20°C, dosage of 6g/L, pH 7, reaction time of 60min to treat 100 mL 20mg/L copper wastewater, the removal rate reached 93.64%.The adsorption of modified water granulated...
Hydrophobic property of concrete with different mixture was studied before and after coating two types of silane products. Adsorption mass of water and NaCl solution of concrete surface were adopted to determine the hydrophobic property. The results show that the water adsorption ability of concrete without silane coating decreases with the higher strength and more air content of concrete. The NaCl...
The coagulation experiment, with Kaolin and humic acids (nature organics) as objects, aluminum chloride (PAC) as coagulant and hydrated MnO2 as coagulant aid, were accomplished under different conditions. In the experiment, the particle size distribution, turbidity and streaming current (SCD) in water were detected by on-line detector. Then the variation rules of particle size distribution and SCD...
Removal of as(V) and as(III) from water using hydrous cerie oxide, CeO2ldrxH2O (HCO) was investigated under different pH and As loading conditions, using batch equilibrium adsorption and FTIR methods. Adsorption of both As(V) and As(III) anions was virtually independent of pH and up to 100% removal can be achieved in the lower concentration range 0.5 - 5.0 mg L-1 As at sorbent dosage of 1.0 g L-1...
Capacitive humidity sensors were fabricated using countersunk interdigitated electrodes coated with amorphous nanostructured TiO2, SiO2, and Al2O3 thin films grown by glancing angle deposition. The capacitive response and response times for each sensor were measured. The sensor utilizing TiO2 exhibited the largest change in capacitance, increasing exponentially from ~ 1 nF to ~ 1muF for an increase...
