“…Some researches on the reactions of aluminum in aqueous solutions have been carried out. [15][16][17][18][19][20][21][22][23][24][25] To obtain a high current density, it is advantageous to use an alkaline electrolyte. But, in the alkaline media, aluminum is very susceptible to selfdischarge by corrosion.…”

The corrosion behavior of aluminum in 1 M potassium hydroxide (KOH) solution with and without calcium tartrate was investigated by means of weight loss measurement, open-circuit potential measurement, potentiodynamic polarization, and electrochemical impedance spectroscopy. Experimental results showed that the corrosion of aluminum was inhibited by the addition of calcium tartrate. At high calcium tartrate concentrations, the anodic and cathodic processes were greatly inhibited. At its low concentration, the effect of the inhibitor on the former was much stronger than that on the latter. This might have been caused by the selective adsorption of the inhibitor on anodic active sites.

“…A quartz crystal resonator comprising two metal electrodes and a thin quartz plate is sensitive to mass changes due to loading on one of the electrodes and the viscoelastic property at the interface of the crystal and its electrode [1] For example, a 9 MHz resonator detects a mass variation of 1.4 ng/Hz from resonant frequency measurement [2] and a viscosity change of 4.3×10 −6 Pa·s/Ω from resonant resistance [3]. This sensitive detection has been used to measure the adsorbed amounts of a specific components in gas [4,5] and liquid phases [6].…”

A new device using dual quartz crystal resonators is proposed to determine the thermal property and morphological change of polystyrene. The resonators are installed in a small aluminum cell directly heated and air cooled according to the programmed temperature variation. The resonant frequencies of the dual resonators-one for reference and the other for sample-are measured and analyzed for the morphological change while their temperature varies. The temperatures of the changes are compared with the DSC thermogram and previously reported studies, and it is found that the measurements are comparable to those of the DSC. The proposed device is simple and easy to construct, and a portable system is available with some modification.

A new monitoring device for the nonisothermal crystallization of thermoplastic polymers, polyethylene, polypropylene, polystyrene, and polyamide, is developed utilizing a quartz crystal resonator, and its performance is evaluated by comparing the measurements with the results of DSC thermoanalysis and microscopic observation. The experimental results of four different polymers indicate that the variation of resonant freency of the quartz crystal resonator is a good means to monitor the crystallization process. Though the measurements of melting and crystallization are close to the DSC outcome, more deviation is observed with the new device. The change in crystalline morphology during the crystallization process is also detected from the slope changes of the frequency decrease. In comparison with the microscopic observation of polymer films, it is found that the processes of nucleation and crystal growth in nonisothermal crystallization can be explained with the variation of the resonant frequency of the quartz crystal resonator. In addition, crystallization kinetics is modeled with the Avrami equation.
