It destroys the hazardous organics and immobilizes heavy metals and radioactive elements, and additionally, it provides volume reductions that can vary between 40 and 99% [5-9].
Results and Discussion 3.1 Heat treatment parameters The preliminary data generated using the DTA technique on an as-quenched sample is showed in Fig. 2 where a slop change at ~700°C indicating a glass transition temperature followed by an exothermic peak, a shoulder one covering the range 750-850°C and well defined one at 923°C.
The high crystallization degree caused a reduction of the open porosity so that the glass-ceramics material showed good water resistance.

In the experiments, nine typical data were chosen and each of them was measured three times.
For a given thickness reduction resulting from the calendering, the smoothness and gloss of papers increased with the roll temperature increasing, and the increasing rate of smoothness was more than that of gloss.
The effect of calendering on a number of paper properties was found to be uniquely related to the thickness reduction resulting from the calendering.

The AuNPs/ZnFe2O4 samples prepared by the colloidal deposition methods were characterized by X-ray Diffractometer(XRD), The diffraction data was investigated 2θ angles between 10°and 90°.
Owing to the existence and stability of the sun, so the photocatalytic properties experiments were evaluated by the reduction of the reduction of methyl orange under UV-light.

These data presented that the development of the information technology is speeding, but there are many problems in the development of Xinjiang electronic government.
The initial Xinjiang E-government applications implemented reflected the traditional views of information communication technology in government, focusing on improvement in speed and reduction in cost of the services delivered.

Various constitutive equations based on dislocation density evolution during hot forming have been developed from the experimentally measured data to describe the sensitivity of the flow stress to the strain [7, 10].
The reduction in height has been chosen as 60% (true strain: 0.9) at the end of the compression tests to avoid barreling.
Moreover, it is observed that error levels decrease by reduction of the strain rate.

Through researches on these phenomena, human have made artificial super-hydrophobic surfaces, applying it to industrial and agricultural and people's daily life, such as ship antifouling, pipeline drag-reduction, anti-icing, anti-oxidation, anti-current conduction[2~6], and so on, for its characteristic of self-cleaning, corrosion-resistance, anti- icing, drag-reduction.
The CA data was averaged by calculating the values measured in five different spots.

It was shown that polymeric organic interphase changes the dispersion of the particles and their sizes, allowing a reduction of working temperature and also the increasing of the catalytic performance [3].
The pores with size of 3.8 nm in diameter seems originated from ceramic matrix and the reduction of the incremental of pore volume for bigger polyester chains is consequence of lesser proportion between carbon and ceramic phase in the composite.
a) b) Fig. 4 Porosity data calculated from isotherms of nitrogen adsorption-desorption at 77 K as function of polyester type pyrolysed at 600°C for 3 hours under nitrogen flux: a) pore size distribution in the mesopore region and b) main pore diameter associated to the pore area.

To quantitatively analyze the effect of starting bias on subthreshold swing, we define the ratio of increased subthreshold swing (∆SSR) as the value of increased subthreshold swing (S) over the value of subthreshold swing with -2V starting bias (SB) and S was extracted from the I-V data between 1nA and 10nA:
∆SSR%=SSB-SSB@-2VSSB@-2V
As shown in Fig.4, the subthreshold swing of MOSFET with GOX1 increased by more than 400% when the starting bias was -15V, while the subthreshold swing of MOSFET with GOX2 increased by only 40% when the starting bias was -20V.
This result suggested that the NBTI of SiC MOSFET can be improved by improving the processes of gate oxide, which, according to the proposed mechanism, was achieved through the reduction of interface traps.
The improvement of NBTI of MOSFET should be due to the reduction of donor-like interface traps populated between the flat-band and valence band edge according to the proposed hole trapping mechanism.

The signal was transformed from analog to digital by Oscilloscope HS3, and the data was analyzed by TiePie software running on laptop.
Reduction of compressive strength of concrete exposed to high temperature is shown in Fig. 8.
The most visible reduction of compressive strength is in range 800 °C to 1000 °C when C-S-H decomposes and decarbonation of carbonates continues.

The TPDRO machine (Thermo Finnigan, 1100 SERIES) was used to study the temperature programme reduction (TPR) for this catalyst at 10 oC/min up to 1173 K. 50mg catalyst was loaded into a glass column which was placed inside the equipment under the flow of pure hydrogen at 20 ml/min.
Ethanol steam reforming was carried out at atmospheric pressure by varying the catalyst loading in the reactor bed from 0.1 g to 2 g at 600 oC, with other parameters were constant such as catalyst reduction conditions, nitrogen flowrate (50% v/v) and steam to ethanol molar ratio (fixed at 6.5 to 1).
It was observed similarly in Hi-FUEL catalyst as there was no ethylene produced at all data points.
