Ferroelectric response under the external electric field was observed using polarization (P-E) studies and electron force microscopy (EFM) was used to study their piezoelectric response and domain structure.

Multi-layer Coating for Optical Mold of Strengthening by Electroplating Ni-W and Electroless Plating Ni-Mo-P by Nonisothermal Method Yun-Feng Chang1, a, Kung-Hsu Hou2,b, Ming-Der Ger3,c 1 Graduate School of Defense Science, Chung Cheng Institute of Technology, National Defense University, Taoyuan, 335 Taiwan 2 Department of Power Vehicle and System Engineering, Chung Cheng Institute of Technology, National Defense University, Taoyuan, 335 Taiwan 3 Department of Applied Chemistry and Material Science, Chung Cheng Institute of Technology, National Defense University, Taoyuan, 335 Taiwan a c31010401@ndu.edu.tw, b khou@ccit.du.tw, cmdger@ccit.edu.tw Keywords: Ni-W, Ni-Mo-P, multi-layer coating, electroplating, electroless plating Abstract.
It's a good adhesion with the substrate and uniform structure, no cracks be found, it has been significantly more smooth on surface topography in Fig. 4 (a), from Fig. 4 (b) shows the cross section view of the Ni-Mo-P coating can be successfully attached to the Ni-W layer to form a multi-layer protective layer.

Inherent advantages of SiC JFET device structure towards achieving prolonged T > 450 °C operation include all-pn-junction isolation and insensitivity to p-type contact resistance.
Temperature and/or pressure without including the complete chemistry (including trace amounts of HCl at 0.5 ppm and HF at 2.5 ppb that were found as reacted products in some samples) is not a sufficient means of screening electronics for long-term operation in the Venusian surface environment.

Chitosan is one kind of ideal polymer which has wide variety of sources, low cost and readily biodegradable, meanwhile there are many free amino in the molecular structure of it, so it has strong adsorption flocculation and superior environmental compatibility.
It perhaps attributed to solution pH influence on the solution chemistry of metals and the activity of the functional groups.
