Due to the huge bandgap bowing, the incorporation of N drastically reduces the bandgap energy with the majority of the reduction resulting from the lowering of conduction band, as in the case of InGaAsN [1].
Good agreement between the simulated and experimental data demonstrates that the In0.050Ga0.950P0.975N0.025/GaP lattice-matched SQWs with excellent crystal quality and fairly flat interfaces have been successfully grown on the GaP substrate.
However, with a reduction of well-width, the PLE absorption edges exhibit lower increasing of the energy than the calculated optical transition energies.

The data indicates that regardless of grazing grassland or ungrazed grassland, N2O emission peak appears in March and April, the spring thaw time, or the most precipitation time in June and July[4].

TWB is the link between high safety requirements and affordable weight reduction.
(a) (b) Fig.3 Vertical pressing mode Fig.4 Inclined pressing mode Calculation of Leveling Force Leveling force is an important data for leveling mechanism design, if the leveling force is too small, the mismatch can not be corrected, and too large leveling force will leading to a bulky design.
Fig. 9 Implementation Structure Conclusion The leveling technology has outstanding effect to the quality of tailored laser welding,especially in the reduction of mismatch.

The specimens were reheated at 1000˚C for 300S and rolled with two pass schedule, resulting in a reduction of 25% and 30% at 950˚C and 900˚C, respectively.
The refinement of bainitic ferrite by increasing the cooling rate could be due to the following: when the cooling rate increases, the reduction in the bainite transformation start temperature (Table 2), Bs, lead to an increase in the driving force (the difference in free energy between the austenite phase and the ferrite phase) for the nucleation rate of substructures of ferrite and, consequently, to a decrease in the width of the bainitic ferrite laths.
The EBSD measurements data were used to analyze the local grain orientation, the grain size and the grain boundary character distribution.

Introduction Accompanying the development of photovoltaic industry, the cost reduction and high efficiency of crystalline silicon solar cells, which dominate almost 90% of the PV production, are faced with most important tasks.
Crystallographic data collection by OIM was performed in a PHILIPS XL-30(FEG) scanning electron microscope (SEM), operating at 25 kV under a step size of 2μm.
On the other hand, the low undercooling value may be a favorable condition to form Σ3 twin boundaries, since the reduction in free energy for the formation of a Σ3 boundary is excess of that for another other type of boundary [10], and the grain boundary energy of the Σ3 twin boundary is quite small, compared with other symmetrical grain boundaries [8],.

They were asymmetrically rolled to 1.5 mm in thickness (83% reduction) at room temperature using a rolling mill with roll diameters of 130 mm.
Some of the asymmetrically rolled samples were continually symmetrically rolled to 0.3 mm (80% reduction).
The corresponding data of mechanical properties is also listed in table 1.

In this work, chemical and mineralogical compositions, acid neutralizing capacity, loss on ignition, salt content were analyzed to provide data for further treatment of the ash.
Content of glass phases reaches around 54%, which is conducive to reduction of energy in recycling of the ash.
The aqueous condition is conducive to reduction of leaching toxicity of heavy metals from the ash, which tend to be leached out into the environment in an acidic condition.

As suggested by the CV data, the peak AIII corresponds to the formation of Fe (V) species seen in Eq. 4.
Fe+2OH—→Fe(OH)2+2e (2) Fe(OH)2+2OH—→FeO2—+2H2O+e (3) FeO2—+ +2OH— → FeO43-+ 2H2O+2e (4) 3FeO43-+ 2H2O → FeO42-+ FeO2—+4OH— (5) 4 OH— →O2+2H2O+4e (6) Three cathodic current peaks are observed and attributed, one each, to the reduction of Fe(VI) to Fe(III), of Fe(III) to Fe(II), and of Fe(II) to Fe(0).The peak CIII corresponds to the reduction of ferrate(Ⅵ) according to the following Eq.7[5].
