The α-MnO2-CNT curve shows a significant reduction current with a reduction peak at -0.2V (versus the standard calomel electrode, SCE) in an oxygen-saturated environment.
The reduction potential of α-MnO2-CNT shifted from -0.28 to -0.32 at 1600 rpm.
The four-electron transfer reaction occurs in the following order: 2+-* (i) *** (ii) *-* (iii) *+-2 (iv) The Koutecky-Levich (K-L) equation can be used to calculate the number of electrons (n) involved in the oxygen reduction reaction, as depicted in Figure 6. using the rotating disk electrode (RDE) data for various voltages.
The K-L equation is presented as follows: (1) (2) (3) The equation used to calculate the electron transfer number in RDE data for various voltages, shown in Figure 6. is given by the Koutecky-Levich (K-L) equation.

The
powder diffraction data were collected between 375 K and 975 K in steps of approximately 8 K/5
min. and evaluated by Rietveld refinements.
The powder diffraction data were collected at Beamline I711 of the MAX-II synchrotron in Lund, Sweden [3].
The samples were packed in 0.3 mm quartz capillaries, open in both ends, and kept spinning during the 5 min data accumulations [4].
Results The raw data (Fig. 1) of the CSS ZSM-5 directly show some important steps in the calcination and combustion processes.

Electrode metal powders are generally synthesized by the wet reduction process [1-2], chemical
vapor deposition method [3] and spray dry method [4].
In this study, Ni powders were prepared by the reduction of hydrazine of Ni salts from diethanolamine (DEA) solvent.
Hydrazine hydrate (N2H4⋅H2O) was used as reducing agent and the reduction was allowed to proceed at 180~240 °C for 0~40 minutes.

Abstract.
Thus, 3D laser scanning was used to acquire geometric feature data, including the length, width, height of unstable rock masses, controlled structural plane, and cutting depth of posterior-margin joints, and to plot the sections of the unstable rock masses (Fig. 2).
Since the saturated cohesion and internal friction angle of unstable rock mass are inaccessible, we adopted similar strata for analogy, and referred to the regional empirical data: 0.21 MPa, 29.8°; the geometric dimensions of the unstable rock masses are showed in Fig. 2.
According to SRM, the slope stability safety factor is defined as the reduction degree of a soil-rock body strength parameter when the slope reaches critical failure, or namely the ratio of actual strength to critical-failure strength of soil-rock body, or namely the reciprocal of the reduction factor [6].

In these methods worker intervention may be required, but it is minimized and the actions of the employee are supported with hardware and software solutions, that enable the reduction of the error rate of data acquisition and increase its speed.
Manual data acquisition Automation, robotics and mechanization allows a significant reduction in human participation in production process, but there are still processes that are not automated, mainly due to insufficient profitability.
Primary data sources.
Secondary data sources.
Secondary data sources can also create new data based on the raw data, that is necessary for control purposes.
