In this research, PdCoNi nanocomposites supported on graphene were prepared by chemical reduction reaction with a strong reducing agent.
Experimental Synthesis of metal nanocomposites supported on graphene The metal nanocomposites were synthesized using simple reduction of metal catalysts and graphite oxide (GO) using NaBH4 as the reducing agent.
The reduction was performed by adding an excess of NaBH4 into the mixture and stirred to obtain a black slurry.
This peak can be used to calculate the electrochemically active surface area (EASA) of the catalysts by determining the columbic charge for the reduction of palladium oxide [6].

The Mn solute
content was evaluated from resistivity data and thermoelectric power assuming that only
Al6(Fe,Mn) was precipitated [5].
The EBSD data also showed that there was a strong β-fibre rolling texture in the heavily cold worked materials.
Taylor factors calculated from the EBSD texture data show a slight increase during annealing, Table 2.
The fits to the HH97 and SH96 data gave exponents ν = 8.4 and 5.0, respectively, but the same activation energy U=225 kJ/mole.
At ν=8.4 a very good representation of the data in Fig. 4 and an activation energy U=100 kJ/mole is obtained from Eq.1.

The data extracted by piezoelectric acceleration sensor is more intuitive, more convenient.
But this method can not realize long distance real time monitoring, there are some shortcomings such as the piezoelectric sensor is still the traditional connection mode, when the number of measuring point is more, the test operation time will be in short [10]; and like that only one sensor can be arranged in a cross section, which can only measure the parameters of a specific section of real-time monitoring, but the long distance real-time changes of the parameters along the line is in need; moreover the data processing must be carried on after the end of the test, which can not monitor in real time.
The development of science and technology provides the possibility for solving the above defects, the distributed optical fiber sensing technology with its unique advantage is particularly worthy of esteem[11]: it can realize remote measurement and monitoring; it can carry on the long distance test, it has high performance ratio; the optical fiber can all become sensitive element, which can acquire the distribution information of measured the sensing area in real time; it can process data in real time, and it can achieve truly real-time monitoring, timely finding and solving the potential problems and harm.
The experimental method obtains data through tests, analyzes vibration propagation and environmental impact through the data.
During the choice of building materials, it is necessary to choose some greater rigidity material, such as while selecting the materials of the ground, the hard materials can be chosen, such as cement floor and terrazzo floor, which have good vibration reduction effect.

Image reconstruction and structural noise reduction techniques are outlined.
Reiterative deconvolution performs the best in such errors reduction (Fig. 6).
Reduction of close proximity errors using iterative (a) and reiterative deconvolution (b) With high accuracy deconvolution available more data can be extracted from the measurement.
Structural noise reduction using SSP enhances the image from the inner layers If separation of desired echoes (deconvolution) is applied then velocity over frequencies range can be evaluated in order to attain new information even for thin materials [15].
Some data can be extracted form straightforward measurements.

The thermal conductivities of cement paste is thus numerically calculated and the predictions are compared with the existing experimental data.
Furthermore, addition of nanosilica particle sizes of 50 nm decreases the thermal conductivity by down to 15% reduction in thermal conductivity compared to the control cement paste have shown in Fig. 2.
Finally, addition of nanosilica particle sizes of 150 nm is a decreases the thermal conductivity by down to 15% reduction in thermal conductivity compared to the control cement paste have shown in Fig. 3.
In order to validate this analytical model for the case of cement paste reinforced by nanosilica, it has been applied to the commercial three contents of nanosilica particle that the predicted results have shown a good correlation to the experimental data.

Though the
main target of the work was to gain a data basis for possible future needs of defect and risk
assessment, an emphasis was put on an evaluation of crack growth mechanisms, too.
Analysed data of crack growth and threshold conditions are a basis for an application of damage tolerance philosophy, which is in case of pressure vessels quite a complicated task due to several reasons: combination of high cycle and low cycle loading with overloading cycles and a very large number of affecting factors as regards corrosion environments like load frequency, waveform, strain rate hold time, environmental parameters - solution composition, corrosion potential, etc. [1,2].
Mechanical properties were: strength 634 MPa, yield stress 507 MPa, ductility 22 %, reduction area 68 %, notch toughness 210 J/cm 2.
The main part of the program concerned FCG in air environment, when effects of overloading in a combination with compressive individual load cycles were investigated [8], besides the measurement of basic FCG data and threshold values at loading with constant load amplitude.
FCG rate reduction in water in comparison with air was in a wide interval of ∆K.

Making full use of the heat of waste gas adapts to the social demand of energy conservation and emission reduction and gains better economic and social benefits.
Table 2 Main parameters of RHF in Kimistu plant Parameters Data Sinter diameter/m 20 Bottom wide/m 4 Hearth area/m2 230 Yield/(t/h) 23 Reduction temperature/℃ 1250~1300 Layers of pellets 1~2 Residence time/min 10~20 The waste gas recycling system is composed by a heat boiler, air preheater (heat exchanger) and a dust washing tower.
The main disposing object of the RHF is plumbum zinc bearing dust and the reduction temperature is around 1000~1300℃.
The pellets then conveyed into deep reduction electric arc furnace where the pellets smelt and the titanium bearing slag separates from the vanadium bearing hot metal.
In order to make sure that the coal and concentrate contact with each other closely to improve the reduction efficiency it is necessary to mill the anthracite to fine powder.
