For this paper, we use the Co loading values measured by EDS analysis in the data analysis and discussion.
Fig. 3 Koutecky-Levich plots for the ORR on CoNC coated glassy carbon electrodes Fig. 3 shows the Koutecky-Levich plots for the ORR data taken at the potential from -0.1 to 0.2 V.
The data comes from the current-potential curves (Fig. 2) obtained using CoNC2.
Its approach contrasts with the theoretical plots for 2- and 4-electron reduction reaction in Fig. 3.
It could be suggested that the CoNC2 can alter the ORR reaction mechanism via both the 2-electron reduction reaction and the 4-electron reduction reaction. 2.3 Scanning electron microscopy measurement Fig. 4 shows SEM images of a sample of CoNC2 catalyst magnified 5000 and 10000 times.

It can be effective for large-scale incomplete ocean data reduction and it also provides a strong basis for decision making for the marine environment processing and follow-up processing.
The prevalence of incomplete data in marine monitoring and other areas of the internet of things bring tremendous difficulties to data fusion, data mining.
In order to mining knowledge from incomplete data, Literature [6] constructed a new similar relationship.
These studies are for static data, but in reality in many databases are dynamic.
Conclusions The traditional approach to deal with incomplete data is make it completed.

Fig. 1 X-ray diffraction data for the mixture of Fe2O3-Ca MA powders as a function of total milling time.
Fig. 4 X-ray diffraction data for the mixture of Fe2O3-Ca MA powders ball-milled for various time intervals and subsequently heat treated up to 600°C.
Fig. 4 shows the X-ray diffraction data for the mixture of Fe2O3-Ca MA powders ball-milled for various time intervals and subsequently heat treated up to 600°C.
Hence, the magnetic data of Fe2O3-Ca MA powders can supply a better understanding of the evidences for the solid state reduction process of Fe2O3-Ca system, as well as the amount of magnetic phase and microstructures.
The X-ray diffraction and magnetic data have been discussed simultaneously in order to achieve a better understanding of the solid state reduction induced by MA.

The experimental data were collected to obtain training set and
testing set.
The results of the ANN model were in good agreement with experimental data.
Finally, 59 groups of data were obtained by experimented.
But, the neural network can be easily over-fitting, which causes the error rate on new unseen data to be much larger than the error rate on the training data.
Fig. 2 shows the root mean square error for both testing data and training data for various numbers of units in the hidden layer by means of trainbr algorithm.

Degradation of Azo Dyes by the Reduction and Oxidation with Nano
Sized Zero Valented Iron
B.H.
Pre-reduction by nZVI could convert azo dye to products whose oxidation is more degradable and therefore enhances the removal efficiency.
The successful use of ZVI has been reported to decolorize azo dye solution by reduction of the -N=N- bond at the iron surface [2,3,4,5].
The laboratory synthesized nZVI used in this study had the specific surface area of 27.9m2/g, which is smaller than the data reported in the literature.
Compared to various H2O2 dosages, pre-reduction of Orange II with nZVI enhanced the TOC removal by 5~15%.
