In this paper, the process of sol-gel method used to prepare LiFePO4/C with different complexing agents was studied, and the analysis of the experimental data based on the ligand field theory was carried out.
Hence, the sharp oxidation and reduction peaks in CV curves indicate that strong lithium intercalation and de-intercalation reactions occurred for LS600 electrode.

It can be seen that the low frequency impedance values all decrease by the increasing immersion time, and the reduction state increase from 3 to 1.
FTIR data have indicated that PAn and TiO2 nanoparticles are simply not blended or mixed up.

However, when wheels are rotating, potion of the flow will be absorbed by the wheels, which contributes to the reduction of the vortex zone.
The reason for above data is as follows: airflow mass (as shown in Table 2) increases when wheels are rotating, which leads to faster airflow speed near underbody and lower pressure.

The data were collected from 25° to 50° with a step size of 0.05° and a scan time of 6s was used.
The LDH release from human monocytes/macrophages increased when cells were in contact with C-HA crystallites, indicating damage to the cell membrane, but the levels of LDH release decreased significantly with a reduction in C-HA concentration from 100 million to 1 million (Fig 3a).

Ref [1] points out that the structure of multi-stator slots is conducive to the reduction motor iron loss.
Table 1 The Parameters of the Prototype Parameter data Number of pole pairs p 2 Speed (r/min) 24000 Stator outer diameter（mm） 81 Stator inside diameter（mm） 56 Outer diameter of PM（mm） 28 Rotor core outer diameter（mm） 18 Length of core (mm) 40 Rotor PM materials N35UH As shown in Fig. 1, the magnetic field is not evenly distributed inside the air gap.

Based on the research, we can get 60 data (10 surface * 6 industrial point) from different low-carbon industry.
A clustering algorithm based on nonlinear reduction dimensionality.

Other than been used as electricity producer, Pico-hydro turbine can also resulted for reduction of CO2 emissions as it can replace fossil fuel and fuel wood to help exploiting local resources, reduces dependence on imported fossil fuel, and saves forests from destruction and soil erosion, cutting down the number of house fires and provides power for recharging portable equipment such as mobile phone [2,3].
The recorded data is also being plotted into a graph for easier observation of the water energy potential.

It is known that doping with vanadium leads to grain refinement, appropriation of viscosity, reduction in brittleness, and increase in the alloy strength [3].
These data suggests that the alloy Ti50Ni48.7Mo0.3V1 has high plastic properties and possesses a well-defined SME.

It shows that the more the reduction of the line width and the increase of the period, the better the infrared transmittance is.
