The reduction of pure WO3 and Ce/WO3 has been studied by using temperature programmed reduction (TPR) and X-ray diffraction (XRD) analysis.
The reduction behavior were examined by non-isothermal reduction up to 900 ºC then continued with isothermal reduction at 900 ºC for 45 min under (40% v/v) carbon monoxide in nitrogen (CO in N2) atmosphere.
The completeness of the reduction of the powder was analyzed by temperature programmed reduction (TPR) method.
For identification purposes of crystalline phase composition, diffraction pattern obtained were matched with standard diffraction data (JCPDS) files.

Selective Catalytic Reduction of NOx on Cr-Mn Mixed Oxide at Low Temperature CHEN Zhihang 1,2,a, LI Xuehui 2, Cen Chaoping 1, GAO Xiang 2, WANG Lefu 2 1.
Introduction Selective catalytic reduction [1,2], plasma catalysis[4,5], catalytic decomposition[4] and so on could be used for elimination of nitrogen oxides.
Intensity data were collected over a 2θ range of 5°-85°.
The XRD phases were identified by comparison with the reference data from International Center for Diffraction Data (ICDD) files.
The performance of pure CrOx, MnOx, and Cr(0.5)-MnOx mixed oxide catalysts prepared by the citric acid, the co-precipitation and the solid state reaction method for selective catalytic reduction of NOx with NH3 is shown in Fig. 1.

With slenderness ratio changing, the variations of experimental data such as axial strain, lateral deflection at mid-height, ultimate bearing capacity, and peak strain were comparatively analyzed.
The ultimate load reduction factor is obtained by regression analysis based on the experimental results of Larch Glulam short columns.
Comparing curves in Fig. 3 with data in Table 2, the conclusions can be made as follows: (1) The trend of the lateral and vertical strain of each specimen was almost the same, so the failure process is divided into three phases [11,13]: elastic phase, plastic phase and failure phase.
Combining the curves in Fig. 4 and the data in Table 2, the conclusions can be made as follows: (1) As can be seen from a) and b) in Fig. 4: 1) Small lateral deflection appears at the preliminary stage of loading, which is caused by physical eccentricity and defects of columns; 2) At the initial loading, specimens suffer mainly compression stress, and lateral deflection at mid-height is almost zero.
The formula of the ultimate load reduction factor for long Larch Glulam columns is obtained by nonlinear fitting, which is: .

Figure 1 shows an eye-diagram of a Pulse Amplitude Modulation (PAM)-4 data transmission on a micro-strip line.
To calculate the data at twice the symbol rate, the transmit data is held for T sec by a delay element.
Figure 4 shows the simulation results of a PAM-4 data transmission using DTHP at 2 GS/s (Symbol/sec) on a 1-m-long micro-strip line.
The transmitter data can be demodulated at receiver by using modulo reduction.

There can be many reductions of.
So, means all the reductions of.
Intersection set of any reduction is a sole kernel.
Thus the minimum attribute reduction is obtained.

Moreover, the reduction temperature of the NSR catalyst decrease first and then increase with the increase of calcination heating rate, and the reduction temperature of as-received NSR catalyst is the lowest as the reduction temperature is 6 °C/min, that is its reduction performance is the optimal.
The specific surface area and pore size distribution of the catalyst were performed by nitrogen adsorption data (NOVA2000, Kangta, USA).
Moreover, the catalyst with the calcination heating rates of 6 °C/min obtains the minimum reduction temperature (459.2 °C), indicating that the catalyst has the best low temperature reduction performance.

The conducted experiments on benchmark data sets validate the proposed approach.
We sampled multiple data sets of data scale of 2000 points from the Swiss Roll Surface.
HLLE will expand removed region, and distort the rest of the data points.
While VK-HLLE is better able to embed the data in two-dimensional space.

The classical metal-organic Frameworks CuBTC showed remarkable low temperature activity in selective catalytic reduction of NO with NH3 (NH3-SCR).
The nature of the active Cu species among CuBTC in NH3-SCR based on the activity data were characterized by TEM, XPS, XRD, EPR and IR.
In this paper, CuBTC was synthesized by hydrothermal method and used for selective catalytic reduction of NO with NH3.
The activity data was recorded when the catalytic reaction practically reached steady-state condition at each temperature.
Conclusions The CuBTC catalysts showed remarkable low temperature activity in selective catalytic reduction of NO with NH3.
