It was found that the YNbO4 is formed in preference to AlNbO4, this demonstrates that Nb is the most avid Y than for Al.

The effect of high-pulsed magnetic field on the unidirectionally solidified Al-Cu eutectic microstructure with 10µm/s withdrawn velocity was investigated.
The rod-like specimen of Al-33.2wt％Cu eutectic alloy with a diameter of 7.0 mm was placed in alumina crucible with 120mm length.

The first Rossendorf paper on this subject was reported by Klabes et al. [4] on the FLA of As-implanted silicon.
Basic estimations of the FLA processing on such ITO-on-glass or polyethylene terephthalate (PET) were already discussed by Gebel et al. [8].
This emitter was the worldwide first Si-based UV emitter which showed electroluminescence (EL) at 316 nm.
An increase of both the annealing temperature and time leads to a decrease of the UV EL intensity.
The sample annealed at 1100 °C for 20 ms (FLA) exhibits a 4 times higher UV EL than the sample treated at RTA.

El Naschie [1] first proposed the concept of chaotic turbulence.
Lahmar et al. [4] proposed an optimized short bearing theory for nonlinear dynamic analysis of turbulent journal bearings.
Chang-Jian et al. [5] established a model of flexible rotor by turbulent short journal bearings.
Chang-Jian et al. [6] established a model of a flexible rotor-turbulent journal bearing system and gave a kind of solution of turbulent long journal bearings by Sommerfeld condition.

For, example, Jafari el al [6] conducted series tests to study the strength of concrete joint samples under normal stress of 4 MPa and shear velocities varying from 0.005-0.4mm/s, as well as different loading cycles.
Simlar works were also conducted by Jing et al, Homand et al, Hutson and Dowding, Lee et al and Plesha [7-11].
Based on the experimental works, Jafari el al and Jing et al [6-7] also primarily presented a constitutive relation of rock joint under dynamic cyclic loading condition.

The alumina and silica supported NiMoO4 catalysts (with Ni:Mo:Al (or Si) = 1:1:10) were prepared by a co-precipitation/impregnation technique in the previous conditions using the same metallic precursors and γ-Alumina and silica as the supports.

The aim of the project was to calculate “run-off” effect of Al and Sn from cans into drink during short-term storage and compare it with WHO norm.

An actual values of release of Al in the form of ions into drink during short-term storage was calculated from half-filled can with selected drink (energy drink in Fig.4).
Quantifying corrosion process in the form of detection of release of Al from can into energy drink after 24 hours it was observed that “run-off” effect reached app. 0.25 mg of Al per day.
Total impedance of Al at room temperature is about 12 times higher than at temperatures around 500C.
