Temperature programmed reduction was conducted using a 25 mg of catalyst on an apparatus (ChemBET Pulsar & TPR/TPD, Quantachrome).
TPR profiles of the samples exhibited two reduction peaks in the range 244˚C and 297˚C, characteristic for the reduction of CuO.
The occurrence of two reduction peaks indicates the presence of CuO species differently interacting with the ceria and zirconia matrix.
Previous authors have observed similar reduction peaks for copper based catalysts and have attributed the low-temperature (L-T) peak to the reduction of highly dispersed CuO or Cu2+ ions in an octahedral environment, whereas the high-temperature (H-T) peak to the reduction of bulk CuO[14].
The data in Table 1 indicated that the performance of bifunctional catalysts was strongly affected by Ce and Zr molar ratios, i.e. catalysts including simplex ceria or zirconia exhibited low CO2 conversion.

The ordinary Voronoi model Voronoi structures are fundamental geometric data structures that appear naturally in a broad range of scientific areas including biology, statistics and computer science [12-15].
Fig. 4 presents the microstructures of extra low-carbon and high strength bake-hardening steel sheet for different cold rolling reductions [17] and the microstructures generated by the modified Voronoi model for the same reductions, respectively.
It can be seen that the topologies of the microstructures in which the grains are elongated, resemble those of the deform microstructures for different cold rolling reductions.
Fig. 5 shows the grain size distributions for different cold rolling reductions.
The topologies of the microstructures are similar to those of the deform microstructures for different cold rolling reductions, and the grain size distributions follow lognormal distribution.

The data for the adsorption dynamics to the ammonia nitrogen are in line with the pseudo-second order kinetics equation, and the adsorption isotherme is well fitted to the Langmuir model.
Introduction With the launch of the ammonia nitrogen emission reduction task in the “Twelfth Five-Year” plan of China, the emission standards of ammonia nitrogen in wastewater are bound to be increasingly stringent, and the method of how to economically and effectively remove ammonia nitrogen from the wastewater to complete the emission reduction task is a key point of wastewater treatment.
This is to accelerate the comprehensive utilization of coal fly ash and the recycling of wastewater of the rare earth industry and provide some experimental parameters and theoretical data for domestic study and practical industrial application in the field.
Therefore, the small pores changed to large pores, resulting to an increased in pore diameter and volume and reduction in specific surface area.
The data for the adsorption dynamics of LaZP to the ammonia nitrogen is in line with the pseudo-second order kinetics equation, and the adsorption isotherme is well fitted to the Langmuir model The desorption rate of ammonia nitrogen improved with an increased concentration of NaCl solution.

Data was collected in the 2θ range of 5°– 90° with a step size of 0.0167° and exposure per step of 27 sec.
Because the raw diffraction data contain some noise, the background during the analysis was subtracted using the Sonneveld and Visser algorithm.
The data were then smoothed using a cubic polynomial function.
The activity of the catalyst was estimated by the number of produced products of the CO2 reduction reaction (mainly methanol CH3OH) per unit mass of catalyst per unit time recorded by a flame ionization detector of a gas chromatograph.

Experiments Conditions Experiments of Coal Flotation A series of conditions flotation test data show that, the best conditions are collector dosage is 0.8l/t, frother dosage is 0.06l/t, slurry concentration is 80 g/L and flotation is 3 min.
It illustrate that a good ash reduction effect will be gotten.
Depressant Action Time Depressant action time has an impact on the ash reduction effect of coal slurry flotation.

The data shows a figure that is very far from the government's target.
The study used data analysis methods, namely logit analysis or logistic regression with multinominal logits.
The collecting data held in February-April in 2023 with google form’s online survey and we share it with facebook and Instagram adsvertisement.
(2) Result and Discussion After the collecting data we get 678 respondens, and from habit’s factor we know that 36,45% respondent who have >60 minutes mobility time in a day choose convensional motorcycle while 60% respondent who have 15-30 minutes mobility time in a day choose electric motorcycle with battery.
Than, we calculate the data with multinomial logit regression.

This semiconducting characteristic was supported by electrochemical impedance spectroscopy (EIS) data which gave Bode plots with absolute frequency and a maximum frequency phase angle values of 38.3° and 75°, respectively.
On the reverse scan, in the negative direction, the reduction peak c' observed at Epc' = +24 mV, can be attributed to the reduction of Pd2+ to Pd0 or of Pd oxide formed during the forward scan.
In the reverse scan, two reduction peaks were observed, peak c' at Epc' = 16 mV and peak b' at Epb' = -445 mV.
The EIS experimental data for PdTe modified electrode in PBS (pH 7.2) were analysed by Nyquist and Bode plots.

The net-trapped charge, Qtrap, is given by ∫= F i E E it trap dEEDQ )( (1) Experimental data shows that the interface trap density (Dit) increases exponentially near the conduction band edge (EC) for 4H-SiC[3].
Reduction in Dit,edge causes a reduction in trapped charge.
The traps cause a reduction in the inversion charge density.
Consistent with our 4H- SiC MOSFET experimental data, this results in lower threshold voltages at higher temperatures as shown in Fig. 6.

The X-ray diffraction analysis demonstrated the presence of acanthite Ag2S on the surface of ZnS/ITO slides, which is consistent with the cyclic voltammetic data.
The cathodic peak C1 is in conjugation with the anodic peak A1 and could be attributed to the reduction of Ag2S to Ag:
The cathodic peak C2 and C3 may be related to the reduction of Ag2O2 and soluble SO42- to S2-.
During the first anodic potential scanning from -1.2 V to 1 V, two anodic peaks were observed, which could be attributed to the reduction of Ag2S to Ag and the formation of S.

However, most of existing feature selection methods are serial and inefficient to be applied to massive text data sets.
It is a NP-complete question to choose representative feature set from massive data set.
So every chromosome corresponds to an attribute reduction subset.
The software tool used in experiment is Weka that is a series of machine learning algorithm related to data mining and developed by the New Zealand Waikato University.
So the ratio of the data transmission time and the whole time is much longer, which leads to gradually lower efficiency.
