Synthesis and characterization of gold nanoparticles
Gold nanoparticles were synthesized with citrate reduction using the method of Turkevich.
Chloroauric acid (HAuCl4) (46.8 mM) was used as the precursor and trisodium citrate dehydrates (2.2 mM) was used as the reduction and stabilizer agent.
All data were expressed as mean ± Standard deviation [22]. 3.

Scholars at home and abroad have done some research on cobalt hydroxide by different methods, for example, controllable electrodeposition method [2], electrochemical reduction[3], wet chemical process[4], sol-gel synthesis[5], hydrothermal synthesized[6].
These data showed that [Co(NH3)n]3+ is the main form of existence in the competitive reaction, Eq. 1 and Eq. 2 occurred rarely by hydrothermal synthesis method.

Introduction
Laccases (benzenediol:oxygen oxidoreductases; EC 1.10.3.2) are multicopper oxidases, which can catalyzes the oxidation of a wide range of compounds coupled to the reduction of molecular oxygen to water with the one electron oxidation mechanism [1].
Data were subjected to one-way analysis of variance (ANOVA) by using SPSS 17.0 software (SPSS Inc., Chicago, IL, USA), and significant differences between treatments was assessed by least significant difference multiple comparison test at p < 0.05.
Whereas, higher moisture contents were reported to cause decreased porosity, loss of particle structure, development of stickiness, reduction in gas volume, and decrease in gas exchange [15].

Vertical displacement of point P (Fig. 1) serves as a comparative data.
Another disadvantage of passive damping is a significant reduction in structural stiffness.
The consequence would be a considerable reduction of the maximum load to which the structure can be subjected.

In the present simulations, the kinetic parameter has not been calibrated by specific experimental data, the unit of cannot be determined.
The reduction speed of grain 2 area fraction is higher with larger .
When the number of particles increases, the reduction speed of the grain 2 area fraction is lowered.

The state –of- art anode (Ni/YSZ) catalysts are deactivated during operation because of the sulfur species amorphous carbon bending to the surface of anode, recently, a symmetrical SOFC using a redox (reduction- oxidation) stable materials as both the anode and the cathode is the effective solution to prevent anode deactivation, especially for the sulfur poisoning effect.
The data were analyzed with ZView software [25].
Where, the values of x = 0.1 and x = 0.2 converge at 800°C, because of a drop in the conductivity attributed to a thermal reduction of Fe3+ to Fe2+ [8].

The high temperature chemical stability of two ceramic materials and DZ40M alloy were respectively studied by microstructure analysis of the interface samples, and the influence of active elements in DZ40M alloy on the interfacial reaction,reaction products and reaction mechanism were discussed based on the thermodynamic data and microstructure analysis.
Therefore, the oxidation-reduction reaction between Ti, Al, Zr in alloy and SiO2 in the core is the main reason for the interface reaction between DZ40M alloy and silica-base core.
The oxidation-reduction reaction between Ti, Al, Zr in alloy and SiO2 in the core is essential for the reaction

The plastic anisotropy coefficients or Lankford r-values are calculated using an automatic least-squares method by fitting the video-recorded specimen width and length strains data between 0.2% strain and the longitudinal uniform strain defined at maximum load.
The tensile strength reduction is due to the coupling between phase transformation and temperature evolution, as shown in Fig. 4.
Summary In this work, the experimentally investigated uniaxial tensile behavior of AISI 304L steel sheet as a function of both strain-rate and plastic strain level showed firstly the coupling effects between the temperature increase with strain-rate, namely, a reduction of the uniaxial ultimate strength triggered by a decreasing of the strain-induced a'-martensite phase transformation.

The reduction in amplitude of a dispersive wave-packet reduces the sensitivity of the testing system.
The reduction in amplitude due to dispersion reduces the sensitivity of the testing has already been reported (7).
Based on the observed data, the resolvable distance of separation of defects could be arrived at.
