Reduction of Hematite by Electrical Discharge Assisted Milling D.
Preliminary discharge milling experiments performed under arc conditions have demonstrated that this technique can be employed for initiation of reduction reactions in metal oxides.
However, further reduction of magnetite to FeO [6] during room temperature milling has proved more difficult, in part, due to the large positive free energy change associated with the latter reduction reaction.
XRD outputs were analysed with Traces Software (GBC Scientific) with search-match capability using the International Centre for Diffraction Data (ICDD) powder diffraction file, 2003 Version (PDF-2).
Semi-quantitative EDS analysis of large sample areas revealed increases in average iron content with increases in milling time, confirming that chemical reduction occurred during discharge milling and that the amount of reduction increased with increasing discharge milling time.

The strengthening mechanism of this Cu-Ag composite is described by a equation similar to the Hall–Petch relationship, the fitted results based on which shows good agreement with the experimental data when the layer thickness is lower than 100-200 nm.
It is also revealed that, good agreement is shown between the experimental data and fitted curve based on equation (2), when the layer thickness is lower than 100-200 nm.
However, the experimental data are quite different from the fitted curve when layer thickness is about 1 μm or larger, i.e., when cold reduction is low.
The varaitions between the experimental data and fitted curve is consistent with the microstructure characteristics and the rule of mixtures discussed above.
Good agreement is shown between the experimental data and fitted curve based this equation when the layer thickness is lower than 100-200 nm.

Drag is usually an undesirable effect and the reduction of drag is associated with the reduction of pumping power requirement in transporting system.
They also suggested that not all drag reduction surfactant caused by viscoelastic since they found drag reduction as non-viscoelastic drag reducing surfactants.
Experimental procedures The pressure drop data in the pipe for water before the addition of anionic surfactants are initially used in the calculations of the drag reduction in which the drag reduction in the pipes is defined as: 1001(%) Reduction       −= b a ∆P ∆P Where ∆Pb and ∆Pa is the pressure drop before and after the addition of the surfactant solution.
At the highest concentration as 600 ppm, the lowest drag reduction was obtained are 4 % at Re = 78645 and the highest drag reduction was obtained are 8 % at Re from 44940 to 56175.
In 400 ppm, the lowest drag reduction is 3 % and the highest is 4 %.

As one cycle sampling has accomplished, arrange the sampling data according to the sampling order the digitization data is obtained [4], as showed in Fig. 1.
Both processing is the function of data processing unit.
In addition, AD9480 also outputs a synchronous clock DCO + and DCO-, which can be used to expand bit wide of LVDS outputs 250MH data stream and achieve frequency reduction.
Differential ADC data transmission and processing technology greatly improves the reliability of data transmission and processing.

The photocatalytic Cr(VI) reduction were performed under visible light irradiation.
Clearly, Cr(VI) reduction efficacy was 5.1% under visible light irradiation in the absence of photocatalyst, revealing the negligible role of self-photolysis on Cr(VI) reduction.
Furthermore, to make a measurable comparison of photocatalytic performance, the experimental data were fitted into first-order kinetic ln(Ct/Co) = kt and shown in Fig. 2b.
(a) Photocatalytic Cr(VI) reduction and (b) the corresponding kinetic analysis.

Abstract.This paper investigated the reduction of benzo[a]pyrene (BaP) in coal tar pitch by modifying with 1,4-Benzenedimethanol, Divinylbenzene and Trioxymethylene.
Results and Discussion The data on reduction of BaP with 1,4-Benzenedimethanol were shown in figure 1 and figure 2 .
Figure 1 Reduction of BaP with 20% 1,4-Benzenedimethanol at various temperature Figure 2 Reduction of BaP with 1,4-Benzenedimethanol of various content at 120℃ The experimental data on conversion of BaP with divinylbenzene in both case, respectively of heating temperature and divinylbenzene content, were shown in figure 3 and figure 4.
Figure 3 Reduction of BaP with 12% divinylbenzene at various temperatures Figure 4 Reduction of BaP with divinylbenzene of various content at 130℃ The both BaP decreasing rate and converting rate are firstly increasing and then decreasing in both cases.
It is also evident from the results that these crossing link monomers bring about the reduction in the following order: Trioxymethylene> 1,4-Benzenedimethanol > Divinylbenzene.

Cycloidal drives are widely used in today’s industries for drives where large reduction ratios are required.
One of the axes of the accelerometer orientated in the tangential direction was plugged into a data collection and analysis device – Labquest (Vernier Software & Technology, USA) to capture tangential acceleration of the pulley.
Thus, when the weight was dropped, the system response would trigger data collection automatically.

The viscosity reduction rate can truly reflect the actual viscosity reduction ratio.
As can be seen from the data in Fig. 2 (left), when the kerosene diluents was added, effect on the viscosity is very large, increasing as the proportion of kerosene, the viscosity decreased from 11 to about 2 Pa.s.
The viscosity reduction plays a role on the heavy oil.
This method can truly reflect the real viscosity reduction rate.
If the method gets promotion, so other researchers can compare the data, to know optimization molecules structure and to explore the polymer structure-activity relationship.

Nevertheless, they suffered from sluggish kinetics of the oxygen reduction reaction (ORR).
In addition, a weak peak from the (1(_)11) plane of copper oxides was observed at about 35.5o in the XRD data, suggesting that part of the copper has not been completely reduced and a very small amount of copper oxides exists.
The earlier the oxygen reduction peak appears, the higher the electrocatalytic activity of the material.
Methanol is oxidized at the anode concomitant with oxygen reduction at the cathode.

Sequentially, the COD reduction data efficiency includes B 20% (88.65%), L 20% (84.2%), A 10% (80%), A 20% (79.92%), ABL 10% (72.3%), B 10% (25.67%), ABL 20% (-10.87%), with the greatest efficiency occurring in the L10% treatment at 89.76%.
COD Levels Data.
The data presented, shows that an increase in graphical data corresponds to a higher percentage reduction in COD levels, while a decrease in graphical data, corresponds to a lower percentage reduction.
Overall, the data graph shows different COD reduction data, with some data experiencing a significant decrease and others showing no significant decrease.
Based on analysis data from the 16S rRNA gene sequence, it was discovered that the third isolate used isolates A, B, and L, was identified as Alcaligenes ammonioxydans.
