After reduction process (reduced form, route (I)), the density of membrane
decreased slightly to 2.21 g/cm3.
There was no significantly change in shrinkage of the membrane in oxidation and reduction form (route (I)).
Each of the data represented an average of measurements at least 5-10 tests.
After reduction with H2 gas, only Al2O3 and nickel (Ni, JCPDS:4-0850) phases were founded as exhibited in Fig. 2(b).
There was no significantly change in shrinkage of membrane in oxidation and reduction form from route (I).

Oxide free Tin nanoparticles were synthesized from a chemical reduction method.
There are two kinds of methods used to synthesize non-noble nanoparticle, one is chemical reduction method, also referred to as the “bottom-up” method, the other one is the physical method called the “top-down” method.
The peak positions of the 30.66°, 32.00°, 44.30°, 45.67°, 56.60°, 62.63°, 64.7°, 66.50°, corresponding with the (200), (101), (220), (211), (301), (112), (400), (321), reflected with face-centered cubic structure by fitting the individual peak profiles with a pseudo-Voigt function (JADE, Material Data Inc.)[10].
The experimental results Summary Oxide free tin nanoparticles were synthesized via chemical reduction method with low-cost precursor, and their thermal properties and crystal structure were studied via differential scanning calorimetry (DSC) and X-ray diffraction (XRD), respectively.

Therefore, the development of cost-effective metallization technologies is very important for the reduction of manufacturing cost.
Electrochemical is a very mature technology, in which an applied current or potential is used to deposit a film of metal or alloy by the reduction of metallic ions onto a conductive substrate [11].
Lack of these data significantly limits the development of photoplating.

Data used in this study is extracted from [2] and [3].
PCA is based on a change in the dimensional plane of the prospected data into a new contracted data set sufficiently representative of the original larger data set [9].
This reduction in data set is always accompanied by an information loss.
As such, a successful PCA achieves the maximum data set reduction with minimum information loss.
Several data points are different then those available in [2] since data was refined and several inconsistencies corrected.

There were significant increase in the shear strength and reduction of moisture content which could be an early indication that sludge which predominantly contains ferric oxide could be strengthen by means of electroosmotic stabilization.
Simultaneously, logging of the vertical settlement measured using vertical distance transducer (LVDT) was automatically done using the data acquisition unit (ADU) and the current was recorded using logging multi-meter.
The electroosmotic tests on the other hand exhibits significant reduction and variations of moisture content especially for the 10kPa-30V test which contains 525% moisture at location close the cathode.
Higher consolidation, meaning higher reduction of moisture content.
The increase of shear strength was contributed by the reduction of moisture content coupled with the probable formation of cementitious material.

The results of heat engineering calculations are presented, where the temperature changes in the reinforcement depending on the heating time and reduction of the protective layer thickness, as well as the change in the diameter of the reinforcement and its effect on the bearing capacity are shown.
Fig. 3 shows the reduction in diameter of the reinforcement during the operational period due to corrosion processes.
This paper takes into account the reduction in thickness δ and considers 6 values (0, 5, 10, 15, 20, 25mm).

The fire resistance during the operational period Summary According to the results of this study, it was shown that a reduction in the cross-sectional area of the working reinforcement due to corrosion and a reduction in the cross-sectional area of the column leads to a significant decrease in the fire resistance limit due to loss of bearing capacity.

Electrochemical test results show that the addition of rare earths can reduce the degree of the plating solution’s polarization, accelerate the electrode reaction speed, increase the alloy reduction capacity, promote alloy’s co-deposition, and improve the bonding strength between alloy layer and substrate, thus the peeling strength between ultra-thin copper foil and carrier is enhanced.
Electrochemical workstation software of AUTOLAB and Origin7.0 are used in data processing.
It can be seen from Figure 2, curve 1 has two smaller peaks at -0.389V and -0.645V, curve 2 has two larger reduction peaks at -0.359V and -0.622V, and two reduction peaks of curve 2 have a little more positive potential shift compared to curve 1.
This fully shows that the addition of rare earth decreases the reduction potential of H-G alloy plating solution, increases the reduction capacity and promotes the alloy deposition speed.
(3)The electrochemical testing results show that the addition of rare earth elements in alloy plating bath can promote the alloy deposition on the carrier foil surface, improve the crystal nucleus formation rate and the metal’s reduction capacity and accelerate the alloy deposition rate.

Cylindrical workpieces were deformed into stepped shafts with cross-sectional area reductions of 35, 52.73 and 75%.
Additionally, the numerical results have good agreement with the experimental data.
That is why the errors in springback are reduced with the decreasing grain size of copper work pieces after MCWR of the same cross sectional area reduction.
Consequently, the MCWR work pieces sprangback more significantly when the area reduction increased.

reduction synthesis routes.
We shall be discussing the role of starch on the aggregation characteristics of copper and silver nanoparticles formed by chemical reduction in aqueous conditions.
Experimental details AgNPs and CuNPs are prepared under two different chemical reduction conditions [3, 4].
SAXS data was collected using Panalytical X-ray generator (PW 3830) having SAXS 896986 Anton Paar mounted on it.
We recorded the SAXS data in the q-range 0.125 to 6.5nm-1.
