Multiple cycles of reduction and oxidization characteristics of the synthesized CoFe2O4 Good redox performance and sintering-resistance are of the great concerns to preserve the reactivity of prepared CoFe2O4 over multiple cycles of reduction and oxidization process, especially used for catalyst or CO2 fixation.
Furthermore, taken the first reduction cycle as an example, the CoFe2O4 reduction by H2 was composed of two reaction stages, one centering at ~480oC with the intensity of TCD signal stabilized as –0.035, and the other shoulder at ~550oCwith TCD signal as –0.015, among which, the former was ascribed to the reduction of Co2+ by H2, and the latter arose from the reduction of Fe3+ involved in the formed CoFe2O4.
Reduction of carbon dioxide into carbon by freshly reduced CoFe2O4 nanoparticles.

Low-carbon tourism is a mode (or model) that tries to protect resources and environment through the reduction of carbon dioxide emissions.
When we do quantitative analysis, it should be easy to collect data.
Thus, it is more appropriate to adopt the inherent data information in the process of analysis.
Both the subjective effect such as the satisfaction of the travelers and the objective effect such as data of the component of the travelers are included.
The indicators used by the evaluation system are fraught with details, and the data used in the evaluating process are convenient to collect.

The operation characteristics of 40kW wind power turbine is provided based on the practical operation data collected within three years and the simulated results obtained from the software calculation.
The general efficiency of this triple hybrid power system in economic and environment aspects is also studied by using and comparing the simulation methodology and the data in practical operation.
extracted power by rotor and caught power by blades area, CM is torque coefficient on the rotor, Cp therefore can be expressed by (2): (2) In practical application, the Cp and area A can be determined by the mechanical characteristics of wind power turbine, they are therefore can be expressed by a constant k, and then the obtained power on rotor and the most appropriate wind speed can be expressed, Supposing power containing in each square meter is calculated based on measured wind speed, is wished fraction of wind power turbine with unit of kW/m2, AWT is wished area swept by wind blades, and then the capacity of wind power turbine can be expressed as: (3) Wind speed in target site is studied based on the measured wind speed data
Hence, the annual reduction in expenditure used for electricity can be derived by converting the generated energy from hybrid system into cost with the ratio of 0.18 USD (U.S Dollar) per kilowatt, and then the reduction of expenditure used for the electricity in different month of the year is shown in Table 3: Table 3: Reduction of expenditure used for electricity in different month of the year We have much more interest in environment efficiency than financial efficiency.
Regarding to the total generation from triple hybrid system, we can easily obtain the monthly reduction of CO2.

To reduce the order of the polynomials of the transfer function the balance reduction method [2] was used.
The measurement of the input/output data for the given lab model. 2.

The determination of the transfer function model and its reduction.
To do this we have connected the whole system ( piezo-actuator, steel beam, piezo-sensor and charge amplifier) to the excitation and data acquisition devices.

On the other hand, annealing at 850°C led to a further reduction of RC , with a slightly increasing dependence of RC on the measurement temperature (here regarded as a “metal-like” behavior).
The experimental data could be well fitted with a thermionic field emission (TFE) model, i.e. with a dependence like [12] with and , FB and ND are the barrier height and the carrier concentration, and C1 is a function of ND, T and FB.
By the fit of the experimental data it was possible to extract a Schottky barrier height ΦB = 0.85 eV and a carrier concentration ND = 1.75´1019 cm-3.
In this case, the data were fitted by the function RC µ Tα, with α = 1.8.
As already demonstrated by combining X-ray diffraction data with EDX analyses on various parts of the layer, the Au-rich regions of such samples can attributed to the presence of the AlAu4 phase [16].

Data from a literature review showed that, for vehicles with internal combustion engine, a 10% curb weight reduction is equal to 4.5 to 6 % increase in fuel efficiency.
A further benefit of less fuel consumption is emission reduction of global warming pollutants.
The three main concepts for vehicle weight reduction are with the use of: 1.
Experimental Data - How They Work Together The three main design tools currently utilized, for vehicle body weight reduction, are the application of AHSS, engineering plastics and light weight metals.
