Structure and Performance of Ti/TiN/PbO2 Electrodes with Plasma-sprayed TiN Interlayer Huang Amin1, a, Zhang Jianxin2, b, Wu Xiaowen1, c, Wang Yang1, d 1School of Materials Science and Engineering, Hebei University of Technology, Tianjin, China 2Hebei Key Laboratory of Advanced Functional Materials aham0130@163.com, bzjxhut@126.com, cwuxiaowen8610@126.com, dwangyang0305@126.com Keywords: Ti/TiN/PbO2 electrode, reactive plasma spray, TiN coating, electrical deposition, oxygen evolution potential, accelerate life Abstract.
The morphology and phase structure of the TiN and PbO2 coatings were examined using a PHILIPS XL33-TMP scanning electron microscope and a Broker AXS D8 FOCUS diffractometer.
It is shown that the coating presents a layered structure because of the heavy impact of droplets on the substrate in the spraying process.
The TiN coating has a layered structure on the cross section and consists of small TiO2.

This structure is similar to the α-quartz, which is stability.
(b) The crystal structure of FePO4 viewed along the x axis.
The improvement could be attributed to the amorphous structure and nano-sized particles.

This may be due to metal/polymer bonding and conversion of polymeric structure into hydrogen-depleted carbon network.
An AC field applied to the metal–polymer–metal structure may cause a net polarization which is out of phase at sufficiently high frequency with the field.

Fig.1a shows the morphology of the amorphous seed crystal which is reticular structure.
According to preferential adsorption law of colloidal chemistry, that is colloidal particles adsorb preferentially the ions which have the same chemical elements with the colloidal particles, and the iron ions had higher concentration in the system, we can infer that iron ions were adsorbed to the surface of α-FeOOH (Fig.1c).
Finally, well-structured coralloid architectures were obtained(Fig.1e).
Then, there are three synthetic ways of crystal structures of α-FeOOH: A.
The crystals grew up in this way until they changed into coral like hierarchical structure composed by nanorods.

NS equation solving aerodynamic is simulated by CFD, and is simulated by the dynamic response of structures for joint solving calculations .Structure and flow fields exchange information with each other through the intermediate data platform..
The unit can also simulate cellular / foam sandwich structure and skin - a combination of the spar cap structure.
It provides the theoretical basis for the design to optimize the structure and properties of the blade.

• For lateral structures in sub-µm range we used the electron beam lithography.
The presented microvalves consist of three layers: a channel structure support, a Pyrex glass cover and a heating structure also providing the electrical interface.
The channel structures are fabricated by wet etching of Si or SiO2 wafers.
The second technique uses photopatterned hydrogel structures (Fig. 3).
Macromolecular chemistry offers different routes to synthesize these gels.

For the PdNi/C sample, Fig. 3(a) showed that the general structure contained spherical nanoparticles of C, Pd, and Ni elements with different sizes less than 100 nm.
Meanwhile, the structure of Ag/MWCNT mainly included Ag nanoparticles heterogeneously attached onto the surfaces of the carbon nanotubes as observed in Fig. 3(c).
