Spark-plasma sintering (SPS) process was used to sinter ZrO2.(8Y) powders, and a relative density of 99% has been reached at a low temperature (13.0°C) and short dwelling time (10 min) compared to the conventional sintered identical samples (1450°C 4 h)(CS). By the X-ray diffraction (XRD) patterns, the microstructure of the SPS pellet and CS pellet are both indexed by the cubic unit cell (Fm3.). The finer crystallite size (D111) of the SPS pellet is 154 nm and D111 of the CS pellet is more than 1 μm. The AC impedance spectroscopy shows that the ionic conductivity of SPS pellet is different from that of CS pellet. The activation energy for the SPS ceramics, estimated from the slope in the range of 400–800°C, was 91 kJ mol?1, which is in good agreement with CS pellet (96 kJ mol?1), indicating that the conduction mechanism in SPS ceramics is similar to that in CS ceramics.

Low frequency noise behaviors of partially depleted silicon-on-insulator(PDSOI) n-channel metal-oxide semiconductors(MOS) transistors with and without ion implantation into the buried oxide are investigated in this paper. Owing to ion implantation-induced electron traps in the buried oxide and back interface states, back gate threshold voltage increases from44.48 V to 51.47 V and sub-threshold swing increases from 2.47 V/dec to 3.3. V/dec, while electron field effect mobility decreases from 475.44 cm2.V·s to 3.3.65 cm2.V·s. In addition, the magnitude of normalized low frequency noise also greatly increases, which indicates that the intrinsic electronic performances are degenerated after ion implantation processing. According to carrier number fluctuation theory, the extracted flat-band voltage noise power spectral densities in the PDSOI devices with and without ion implantation are equal to 7×10-10V2.Hz-1and 2.7×10-8V2.Hz-1, respectively, while the extracted average trap density in the buried oxide increases from 1.42.1017cm-3.e V-1to 6.16×1018cm-3.e V-1. Based on carrier mobility fluctuation theory, the extracted average Hooge’s parameter in these devices increases from 3.92.10-5to 1.3.×10-2.fter ion implantation processing. Finally, radiation responses in the PDSOI devices are investigated. Owing to radiation-induced positive buried oxide trapped charges, back gate threshold voltage decreases with the increase of the total dose. After radiation reaches up to a total dose of 1 M·rad(si), the shifts of back gate threshold voltage in the SOI devices with and without ion implantation are-10.82.V and-3..84 V, respectively. The low frequency noise behaviors in these devices before and after radiation are also compared and discussed.

The enzymatic degradation of poly（ε-caprolactone）（PCL） has been investigated by using quartz crystal microbalance with dissipation （QCM-D） and surface plasmon resonance （SPR） in situ. The frequency and dissipation responses of QCM-D and the SPR signal responses can well describe the weight loss and the morphological changes of a PCL film. Our experiments reveal that the degradation has much dependence on the crystallinity and morphology of PCL. PCL with lower crystallinity （45%） and small spherulites degrades in a way of layer-by-layer. Both QCM-D and SPR measurements demonstrate the degradation is of first-order. However, PCL with higher crystallinity （55%） and larger spherulites exhibits a more complex degradation behavior;namely, the degradation in crystalline region lags behind that in amorphous region, leading to a microporous structure.
