To date, numerous synthetic protocols have been developed to prepare TMDs nano-materials, including thermal reduction, high temperature sulfurization, hydrothermal method, chemical vapor deposition (CVD), and even laser ablation, and a substantial number of inorganic layer-like materials of TMDs have been prepared and characterized, such as WS2, NbSe2, MoS2, MoTe2, TiS2 and so on.
The tests of friction reduction and wear resistance were performed at rotating speed of 400 rpm under the load of 10-30N for 20 min.
Fig.1 XRD patterns of pure TiSe2 and standard card no.30-1383(a) and the full width at half maximum data of the characteristic spectrum peak (b) 3.
It could also be observed that the (100) peak were fatally weakened, and however, (001) and (002) peaks became stronger and sharper with the reaction temperature at 800℃, and the full width at half maximum (FWHM) data can be seen from (Fig.1b).
At the reaction temperature of 600℃, Ti and Se react with each other to form TiSe2 primary irregular particles with the size of 50-100nm through anoxidation-reduction reaction at the initial stage (1h) as shown in Fig.4a.

Moreover, due to the universal occurrence of the reduction of beneficial plant microorganisms and rapid proliferation of pathogens, we supposed that some potential antagonists and plant beneficial microorganisms may disappear in such a process.
Data for plate counts were compared with Duncan’s multiple range test (SPSS 12th edition), with a designated level of significance of P < 0.05.
Results Changes in culturable bacteria Plate count analysis revealed a reduction in the number of culturable bacteria in rhizosphere and bulk soils as cucumber cropping continued.
Our data appears to confirm this speculation, for rhizosphere samples with less EP-index were always associated with higher disease incidences.
The two known bacterial species with population reduction were most closely related to Pseudomonas sp. and Bacteriovorax sp.

A meter makes it possible to calculate the residence times of the system in the various levels of degradation in order to account for the losses generated by the reduction or cessation of production.
The set1 has two levels of degradation, a degraded state (degradé_1) accompanied by a reduction in production, an out-of-service state (Hs_1) with a total loss of production.
We are working on real data and information about this system [14].
The reduction of the implementation complexity of our system during future use will be represented by a single block and with a parameter λ (t) whose discrete values are recorded in a database.
Conclusion Until now, feedback data and information from manufacturers, which are often too weak, raise difficulties to define a quantifiable and cost-effective maintenance strategy.

The obtained data is correlated with standard spectrum.
According to the results of table 3, conjugation has significantly reduced the MIC and MBC of gentamicin against E. coli that can cause reduction of effective dose and also side effects.
In the present study, conjugation of gold nanoparticles with gentamicin caused significant dose reduction against E. coli and also disappearance of resistance of C. botulium and C. perfringens to gentamicin.
These results are in agreement with Bhattacharya and Saha (2007), that reported significant reduction in MIC of kanamycin and streptomycin conjugated with gold nanoparticles and more thermal stability was found in conjugate.
The data of this study provides an insight for in vivo studies.

An Experimental Study of Steam Gasification of Biomass over Precalcined Copper Slag Catalysts Shuanghui Deng1,a, Jianhang Hu1,b,*, Hua Wang1,2,c, Juanqin Li1,d and Wei Hu1,e 1Engineering Research Center of Metallurgical Energy Conservation & Emission Reduction, Ministry of Education, Faculty of Metallurgical and Energy Engineering, Kunming University of Science and Technology, Kunming, 650093,China; 2State Key Lab.
However, the growth of the heating value caused by the increase of the H2 content was insufficient to compensate for the reduction of the heating value caused by the reduction of the CH4 and C2Hm content.
According to analysis data of the product gas, the optimal catalytic activity could be obtained at the precalcination temperature of 1000℃.
Comprehensive comparison of all the data showed that in the case of copper slag precalcined at 1000℃ for 5h the amounts of the gas yield, the gasification efficiency, the steam decomposition efficiency and the hydrogen yield reached the maximum in this study.

For the commercial application of the SOFC technology, there are some importance requirements on the cost reduction, performance enhancement, and long-term stability.
The criteria of the accuracy between the experimental data and the simulating result which combines the five variables is defined by that the value of the Gaussian Distribution of Activation Energy Accuracy (GDAE accuracy) is set at 2.
The fitting lines are well consistent with the measured data, and the fitting parameters of the EIS analysis of the cell under different operation times and temperatures are plotted in Fig. 7.
Some studies have observed the cathodic polarization loss and indicate that this effect is attributed to the change of the three phase boundary (TPB) and / or the microstructure, the remove of the surface passive layer associated with the segregated phase of the Sr and / or La species on the surface of LSM, the partial reduction of the cathode, and the formation of the oxygen vacancies [33-36].
That is inconsistent with the literatures that propose that the electrode polarization is mainly attributed to the reduction reaction of the oxygen in the cathode due to the poor activity of the catalyst.

The formula for fitting the experimentally obtained data from the fatigue test used in this paper is based on empirically derived S–N diagrams known as Wöhler curves: S=a×Nb, (1) where a, b – the material constants characterizing the S–N curve.
The correction of the fatigue strengths to the selected corresponding age of the specimens turns out to be very important since the smallest calculated correction was 80 % for a reduction of 84 days (for specimens of reference composite without fibers).
The largest correction is represented by a value of 68 % corresponding to a reduction in age by 149 days (for composite with the dosage of 0.5 % of steel fibers).
In these figures, measured data are plotted for a standardized specimen age of 28 days; filled marks indicate a successful fatigue test, and unfilled marks indicate unbroken specimens.

As shown in Figures 2, the erosion behaviours achieved from pitting depth measurements and eroded volume measurements are similar. 3.2 Absorption kinetic, an influencing factor of erosion It is possible to use the data regarding water absorption provided in the work of (Guihéneuf et al., 2020b) in order to analyse the link between erosion and material characteristics.
The dispersant additions permit generally an ACap/n and Pd reduction.
These additions reduce the capillary water content, suggesting a reduction of the water quantity that can be absorbed by the material.
The ACap/n reduction is more pronounced when the vegetal based varnish is coated on the samples, but this could not be a viable solution in long-term if water pass through this coating protection.

The dense network of seismographs deployed in this region recorded ground motion acceleration data with good quality.
During the Wenchuan earthquake, most stations recorded three-component ground motion acceleration data completely except 11 stations, of which the data missed completely or partially.
In this paper, 94 suites of typical three-component data with larger peak ground acceleration and longer duration were chosen to investigate vertical ground motion characteristics of Wenchuan earthquake.
Because more than 90% stations are located in the soil site and all the data are from the Wenchuan earthquake, the influence of magnitude and site condition on Tp were disregarded and the epicentral distance is considered only.
(3) The site condition has some influence on av/ah, and further analysis and research on the influence of site condition and focal mechanism on av/ah will be needed with the accumulating of ground motion data

The experimental data was found fitted well with the pseudo-second-order model, an indication that chemisorption was the rate controlling mechanism.
The above adsorption data was further analyzed by using two kinetic models; pseudo-first order and pseudo-second order kinetic models.
Based on the R2 values (Table 1), it was found that the pseudo-first order model did not fit well to the adsorption data.
The data obtained from the isotherm study was interpreted by using Langmuir and Freundlich isotherm models.
The Freundlich isotherm data is listed in Table 2.
