Under cyclic fatigue, a reduction of crack bridging is observed, followed by a decrease of the compliance function.
In a recent work, the authors have applied a procedure, which allows for bridging stress determination and R-Curve evaluation from compliance data [6-8].

In recent years, there has been a strongly growing demand for the use of metallic foams, particularly aluminum foam, for automotive, railway and aerospace applications where weight reduction and safety improvement are needed [2-3].
Moreover, the strength doesn't change so much with increasing from 0% to 15%, although there are some data scattering, which is attributed to non-uniformity of particle and height difference of specimen fabricated.

On the early step, the Raman data were compared with the theory based on the Drude model, but more recently the Lindhard−Mermin expression for the dielectric function was used.
The main effect of screening is a reduction of the phonon frequency from LOω to TOω when the number of carriers increases.

Data of shrinkage along the pressure axis, temperature, and electrical power input were automatically stored through a dataacquisition system into a PC.
This can be ascribed to the reduction of particle sizes by ball-milling.

Moreover, the azobenzene substituent with a longer alky spacer attaching to the polythiphens backbone can give rise to a reduction of steric hindrance and consequently oxidation potential for electrochemical polymerization.
The NMR data of the resulting compound is in agreement with its structure.

It was also found out that increment of austempering temperature from 260°C to 390°C resulted in reduction of hardness values due to increment of austenite percentages in the microstructure [12].

This peak at 350 K could contribute significantly to the reduction of the mobility for transistors with oxide grown by pyrogenic.
To determine the interface state density (Dit) as a function of the bandgap energy, we have performed theoretical fit to experimental data Fig. 7.

The synthesis, performed at temperatures between 1050-1100°C in an open-tube, is based on the carbothermal reduction of silica present as the native oxide on the substrate surface [2].
In agreement with literature data, the emission at 1.73 eV can involve deep levels in 3C-SiC with an activation energy of about 0.5 eV [8-9].

Meanwhile, the feedback signals that actual measure data is processed into two parts: Position quantity p2 and speed quantity v2, then the single position error that converts into a single position error and a velocity error of two parts.
According to the given velocity, this can make the system to avoid the blindness suppression of the speed and the amplification of noise and achieve the purpose of error reduction.

From the figure, we can see that the Cu2+ oxidation-reduction peak high and the half peak wide both increases with increasing the Cu2+ concentration.
