It was found that β1 ordered bct phase with the
axis ratio c/a=0.948 was formed in the AuMn alloy due to the Mn reduction by evaporation during
melting.
The crystal structure data and lattice parameter of β1 are listed in T able 2 and the schematic crystal structures are shown in Figure 4.
On the other hand, the lattice parameter of Laves phase is slightly decreased by reduction of Au content.
Crystal structure data and lattice parameters determined by XRD.
Based on the experimental data, the phase constitution at 873 K along the AuMn-Cu2MnGa is visualized in the Au-Cu-Mn-Ga quaternary system as shown in Figure 6. 10 μm γ L 1 μm β2 P L γγγγ 5 μm (a) AuMn (c) CuMn 0.5 Ga 0.5 (b) Au0.5Cu0.5Mn0.75Ga0.25 20 μm β1 MnO or Mn3O4 10 μm γ L 1 μm β2 P L γγγγ 5 μm (a) AuMn (c) CuMn 0.5 Ga 0.5 (b) Au0.5Cu0.5Mn0.75Ga0.25 20 μm β1 MnO or Mn3O4 Fig. 5.

This vibration has a great impact on the dynamic stability of the mill and rolling reduction, and will significantly reduce the dimensional accuracy and surface quality of seamless steel pipe.
The calculation results of rolling force of tandem rolling mill are compared with the measured data and the results are shown in Fig. 3.
The dynamic response value of the roll may be optimized by controlling the reduction, friction coefficient, rolling speed and so on.
The rolling speed is 600 mm / s, the friction coefficient is 0.3, and the reduction is 15%.

And another main reason could be the reduction of adsorption sites due to the occupation of iron nanoparticles.
Chlorophenols as a group of organic compounds are very stable under aerobic conditions in both soil and water, amendable to biological and chemical reduction only under specific environmental conditions.
The data showed that the concentration of Cl- increased along with the reaction time, though the removal of PCP had already finished within 2 h.
Besides, the reduction of adsorption sites due to the occupation of iron nanoparticles would be another important cause.

There are two ways that environmental packaging plays a catalytic role of low-carbon logistics: First, the reduction of packaging materials and R&D and application of green packaging materials; second, the green and environmental protection in the design and application of packaging mode.
Therefore, the logistics management process is considered mainly from the overall situation of logistics supply chain beginning with energy-saving and emission reduction targets, using modern management and technology so that every link of logistics system can share general information, and then put all links as an integrated system for organization and management to provide competitive customer service in the condition of an total cost as low as possible, including process low carbonization in the whole logistics system with positive logistics and reverse logistics involved.
Reduction of packaging materials and the applications, research and development of green packaging materials.
To realize the informationization of whole logistics process needs bar code or some other RFID (Radio Frequency Identification) techniques to reflect the specific information of the cargo within, and makes use of EDI (Electronic Data Interchange) system to form a high-precision logistics information system.

On the other hand, mixtures with OI content up to 50% showed reduction of water absorption and firing shrinkage, while flexural strength was increased.
The waste OI pure presents an abrupt reduction of water absorption at sintering temperatures between 1130°C and 1080°C, showing that some reaction has occurred.
Analyzing data of X-ray diffraction, it can be seen that the waste OI stands out due to the high content of microline and plagioclase, together with quartz, enstatite, biotite and edenite.

Abstract. 4-Phenoxy-4', 4''-diaminotriphenylamine was synthesized from N, N-diarylation of 4-amino diphenyl ether and 4-fluoro nitrobenzene, and subsequent reduction of the resultant dinitro compound.
Results and Discussion Monomer was synthesized by double N-arylation reaction of 4-phenoxyaniline and two equivalent amount of 4-fluoronitrobenzene in the presence of cesium fluoride, followed by hydrazine Pd/C-catalyzed reduction of the intermediate dinitro compound.
After the reduction, the primary amino groups showed the typical absorption bands at 3459 and 3329 cm-1 due to N-H strentching. 1H NMR of the diamine monomer was agreed well with the proposed molecular structure.
Comparing the electrochemical data, it can be found that –OCH3 substituted triphenylamine was a little more easily oxidized than –OC6H5 substituted triphenylamine.

Screening of FeSNPs for dye reduction using methylene blue.
Screening of nanoparticle preparations for reduction of dyes.
The ability of NPs to cause reduction of MB dye was used as a measure of the efficiency of decolorizing dyes by chemical reduction process.
Among the preparations tested, it was found that FeSNPs synthesized in-vacuo and capped with plant derived polymer BP were most efficient (>80 %) in reducing MB compared to other capping agents (efficiency 30-60 %, data not shown.
Removal of Acid Black 1 from solution using selected FeSNPs It was observed that maximum efficiency (85 %) of Acid Black 1 removal was obtained when the concentration of dye was 20 mg/L (data not shown).

The
experimentally verified 'Corrected Brinson Model' [4,5] provides fundamental, and accurate
performance data for developing models for integrating SMAs within beams, plates, and shells.
This predicts a 26.2% reduction in the rotor forward-whirl amplitude at resonance, however in practice certain material availability restrictions for the single-ended active bearing meant that 10% less SMA was fitted than was actually modelled.
It is relevant to note that this downshift principally occurs because of the pronounced shift in the resonant point along the frequency axis rather than any significant overall reduction in forward-whirl amplitude at the displaced resonant point.
Specific code was written to do this calculation for blocks of data, and a typical result is given in Fig.4.
Amplitude reductions at the first critical speed of around 5-10% were recorded using this system, noticeably lower than in the open-loop tests performed earlier.
