Yeob Lee et al. reported the visible-light responsive photocatalytic behavior of NiTi-LDH under a coexisting sacrificial reduction reagent such as AgNO3 [2].
Graphene was obtained successfully by a thermal reduction of graphene oxide in ambient atmosphere at a temperature of 1000 °C for 30 s.
Table 1 shows the parameters of each photovoltage profile, a decay rate of photovoltage kd (sec-1) was calculated by fitting of eq. (1) described below to experimental data by least-square method.

In particular, using Tailored Welded Blanks (TWB), significant advantages can be obtained in terms of weight reduction, fuel consumption and economical and environmental impact.
One of the most effective solutions allowing weight reductions without compromising the integrity of the structure is the use of mixed structures composed by elements in magnesium and aluminium alloys conveniently joined.
Ts and Te, A and D data were chosen in such a way to get the material phase transformation taking into account aluminum and magnesium alloys at the beginning of the numerical simulation and to avoid any transformation back during the process.

Anacardic acids, which are antimicrobial substances employed in the reduction of Ag+ to Ag.
The reduction in thermal conductivity with temperature can be attributed to the fact that temperature altered the original crystal structure of the materials and expose more free electrons and phonons to conduction.

The outlined model requires input data relating to the response of the system,
i.e., displacement (x) and velocity ( x& ) , in addition to the applied voltage (v).

At potentials more negative than - 1.2 V, the
junction is blocked, the reduction current being smaller than 20 µA/cm2 at - 2 V.
The reduction current density is smaller than 0.7 A/m2 at - 1 V.
As for as the refractive index of porous silicon (1.3 - 1.6) is lower than that of alumina (1.65 - 1.77), values correlate well with the previously reported data [3], the anodic alumina layer provides an appropriate light guiding effect.

Experimental data of the coated P-91 and linear fit of the
logarithm of the deposition rate versus 1/T.
In comparison with the single aluminization, the addition of Zr causes a great reduction of partial pressure of AlCl3 chlorides leads to increase the proportion of AlCl (the principal source of Al in the deposition) and an increase in the deposition rate.Coatings are formed of (Fe,Cr)2Al5 intermetallic phase.
The highest coating thickness is found where 4wt% of Zr in the reactive bed is added and increasing the %wt of Zr causes a reduction of the thickness.

For the tensile test at 973 K, fracture occurred in the elastic region regardless of the carbon and nitrogen doping, so that only the data for the tensile strength (fracture strength) were plotted in this figure (Figs.3b and 3e).
At 773 K, a brittle intergranular fracture mode dominates in alloy Base, resulting in the reduction of tensile elongation as shown in Figs.3c and 3f.
The absorbed hydrogen migrates on rapid diffusion paths such as grain boundaries and dislocations and reaches to grain boundaries in front of a propagating micro crack, resulting in reduction of tensile elongation and fracture strength.

A coating thickness of only a few µm enables full corrosion protection and a reduction in oxidation rate.
Once perfected, this process will offer huge energy savings of up to 85 per cent, reduction of emissions by over 70 percent and capital cost savings over conventional casting and rolling processes for producing steel sheet products.

Introduction
A huge amount of energy is usually consumed in
the reduction process of alumina to aluminum in
the electrolytic cells.
A study on the sources of phosphorous in aluminum reduction cells proved that about 50% of the phosphorus pick-up by the electrolytic bath stemmed from corroded collars [6].
The expansion values of FDI, PDI as well as LPGI may explain the electrical resistance data indicated in Fig. 5, where more expansion leads to higher contact pressure and, hence, lower electrical resistance at the stub-collar-anode connections.
