Song et al. [9] reported that the strength of Sn-1Ag-0.5Cu solder was increased by additions of <1.0 wt.% Zn, but decreased at Zn content of 2.0 wt.%.
Wang et al. [14] reported that in Sn-0.7Cu-1.0Zn, some dispersed particles were appeared and mainly located at the boundary between the refined β -Sn phase and the eutectic lamella.
Zhang et al. [17] reported that the optimal wettability was obtained with the addition of 1.5wt.% Zn in Sn-Ag-Cu solder alloy.
Kamal et al. [18] also found that the wetting property of Sn3.5Ag solder can be improved with the addition of 1.5wt.% Zn but decreases significantly when Zn content increases up to 3.0 wt.%.

For example, morphology-controlled polygonal ZnO nanobowls have been fabricated by Yang et al. [4, 5] via colloidal-crystal-assisted imprint method and solution dipping.
Ye et al. have presented a method to fabricate gold nanobowls via ion milling and vapor HF etching technique, and these gold bowls have shown a promising application in SERS-based biomolecular detection [6].
TiO2 nanobowl ordered arrays have been fabricated from polystyrene monolayer templates and atomic layer deposition by Wang et al., and they were proved to be useful for the submicron spheres selection and subwavelength photolithography [7, 8].
Li et al. have also presented a method to fabricate TiO2 nanobowls via a block copolymer templating and sol-gel process [9].
The dispersion was spin-coated onto silicon substrates by a spin-coater (EL-S-200, Solar-Semi).

The reseaches of Jiang et al. [7,8] and Molodtsov et al. [9] are employed into the current study.
To estimate the longitudinal interations between α/β tubulins and GDP molecule within a protofilament, Jiang et al. [7] modeled tubulin as a grid ball with a diamter 4.8 nm and a GDP molecule as a rigid ball with a diameter of 0.55 nm which are connected with the non-linear springs. α/β tubulins are composed of carbon (C), hydrogen (H), nitrogen (N), oxygen (O), and sulfur (S), and a GDP molecule is composed of carbon (C), hydrogen (H), nitrogen (N), oxygen (O), and phosphorus (P).
Jiang et al. [7] adopted the Lennard–Jones 6–12 potential for the van der Waals interaction, and obtained an analytical expression for the energy density that is contributed by the longitudinal interactions as (1) where h is the distance between the centers of the tublin and GDP molecule.

Moreover, the new time parameters used to produce the slurry – including the swirling time, resting time and drainage time (if applied) – yield to a slightly shorter total time cycle for the slurry production, as presented schematically in Fig. 8.
The same approach was applied to other common AlSiMg foundry alloys in die casting [6].
In a recent project with Duralcan Al9%Si20%SiC composite, it has been found that the slurries produced by the SEED process without drainage have a good process response for semisolid forming and that sound, netshape die cast parts are produced.
The solid fraction, aAl grains and SiC distribution can be optimized by adjusting the process parameters, which demonstrates the great flexibility of the SEED process.
Microstructures of (a) the semisolid slurry produced by nondrained SEED process and (b) the die cast part, showing globular aAl gains and uniformly distributed SiC particles Conclusion The SEED technology for rheocasting of aluminium is now available without the drainage phase.

A systematic investigation of the Ba2B

//5+O6 (B

perovskites has been presented in the works of Zurmuhlen et al. [6, 7].
The value of TC� for Ba2MgWO6 agrees well with that obtained by Zurmuhlen et al. in [7], 50 ppm K -1, at microwave frequencies.
Reaney et al. [9] have established a relationship between the temperature coefficient of the permittivity, which is close related to the TCf (TCf = -TC�/2 - �; � is the linear thermal expantion coefficient) and a structure tolerance-factore (t) for Ba- and Sr-based complex perovskites A 2+(B /nB // 1-n) 4+O3 as well as their solid solutions.
A correlation between TC� and t has been presented by Reaney et. al in the form of a diagram [9].
