El Naschie that the nanoage is something of a Hemingway line of demarcation between the have and the have nots [1].
The ultrasonic vibration can greatly reduce the viscosity of the solution, making the impossible possible, see articles by Wan et al. [7] and Si et al. [8].
In this issue, a modification of the bubble electrospinning is suggested by Dou et al. [11].

For the electrical measurements, Au or Al electrodes with planar geometry were contacted to the sample surface and fasten together.
The present value seems to be slightly smaller than 0.38–0.45 eV of previous results reported by Reddy et al [1].

Hanafi et al. estimated cutting parameters in turning of PEEK-CF30 using TiN tools under dry machining, to attain minimum power consumption and the best surface quality using Taguchi and grey relational method [4].
Another work was a study into the effects of cutting parameters and nose radius in turning of 7075 Al alloy SiC composite to minimize power consumption and maximize tool life [5].

Kulkarnia at el [1] studied the ratcheting in pressured straight piping under cyclic bending load using four points bending equipment and analyzed the ratcheting strain with the Chaboche constitutive model in ANSYS.
Yahiaoui at el [2] discussed the location where the ratcheting may happen based on the elastic finite element analysis results in the elbow under in-plane cyclic bending load.
Gao et al [3] analyzed the cyclic plasticity in pressured elbow under out-plane bending load using finite element method and perfect elastic-plastic model.
Gao et al [6] has concluded that the ratcheting strain mainly occurred in circumference.

Effect of solution-treatment condition on texture of a Ti-Mo-Al-Zr shape memory alloy was investigated by X-ray pole figure measurement.
Ti-Mo-Al-Zr alloy is a Ni-free and β-Ti based biomedical shape memory alloy.
In a Ti-Mo-Al-Zr shape memory alloy, it was reported that {110}β <001>β recrystallization texture (Goss) is developed by the solution-treatment as the reduction rate increases, unlike some Ti-Nb based SMAs [5-10].
The purpose of this study is to investigate the effect of solution-treatment condition on the recrystallization texture in the Ti-Mo-Al-Zr shape memory alloy.
This result is in good agreement with the results obtained by Hiramatsu at el [5]. {227}β <110>β and {378}β <112>β are not common as deformation textures of bcc metals [11].

El-Hamid et al, [8] synthesized biocement C3S nanocrystal with sol-gel and solid state methods.
ACS, Sigma-Aldrich, Germany), Al(NO3)3⋅9H2O (~98.5%, Reag.
WMTA was synthesized by the sol-gel method as Lee et al. [9] with modifications to the composition.
Radiopacity of WMTA WMTA radiopacity test was carried out to see the content of mm Al and to see the equality of radiopacity between dentin and aluminum (Al) which had the same thickness [21].
