The influence of cosurfactant content and the hetero- geneous distillation process on the structure and properties of the particles was studied.
The influence of cosurfactant content on the structure and properties of zirconia nano-particles were particularly investigated.
Crystal structure.
This is because that the microemulsion method is a wet chemistry method, in the process of drying Zr(OH)4 wet gel, with the water evaporation gradually, particles fall closely together due to hydrogen-bonding formed by small amounts of water between particles and huge surface tension of particles.
The cosurfactant content has little influence on the crystal phase of ZrO2, but has some influence on integrality of ZrO2 crystal structure.

The chemical structure of polyurea differs from that of polyurethane, which is formed by the reaction of an isocyanate and a hydroxyl.
The chemical structure of Polyurea makes it an excellent barrier that significantly inhibits environmental attack and electrolyte penetration, thus providing long term corrosion protection.
Thanks to the ongoing research in the chemistry world, new and better Polyurea products are continually developed.
The whole structure is located 12 meters underground, in proximity to the Mediterranean.

The result shows that CuInS2 film with chalcopyrite structure can be successfully prepared by one-step electrodeposition.
The influence of annealing temperature on the structure and morphology of the film was highlighted.
The crystallographic phase structures of the film were characterized by an X-ray Difractometer （XRD，Rigaku, Japan） with Cu Kα radiation(λ=1.5406Å) at 40kV and 150mA.
Conclusions With the improvement of annealing, CuInS2 film with chalcopyrite structure can be successfully prepared by one-step electrodeposition.

Structure and piezoelectric properties of (1-x)K0.49Na0.51NbO3-xLiTaO3 lead-free piezoceramics Yue-Ming Lia, Liang Jiang, Zong-Yang Shen, Run-Hua Liao and Zhu-Mei Wang Dpt.
It can be seen from Fig. 1(a) that all ceramics have the single-phase perovskite structures with LiTaO3 contents x up to 0.07.
All these characteristics demonstrate the ceramics has an orthorhombic perovskite structure at x ≤ 0.04 while become tetragonal one at x ≥ 0.06.
The ceramics show an orthorhombic perovskite structure when x ≤ 0.04, while changes to a tetragonal one when x ≥ 0.06.

The crystal structures of sintered samples were determined by X-ray diffraction.
The BNTK100x ceramics are all of pure perovskite structure.
According to the principle of crystal chemistry, K + (1.64Å) is most likely to go into A-site in perovskite system substituting Na +(0.99Å), while Nb5+(0.64Å) could substitute for Ti4+(0.61Å).
This result is consistent with the change of phase structure determined by XRD.
Conclusion All composition investigated in this study can form single perovskite structure.

To meet the above requirements, steel chemistry was developed that corresponded to formula 0.07%C-1.6%Mn-0.075%Nb and complied with the present-day requirements HTP-steels, characterized by lower carbon and produced by thermomechanical controlled process (TMCP).

Comparison of К(НV1.96) for pipe steels with different chemistry shows that with lower carbon in steel from 0.19 % to 0.06 % the structural non-uniformity coefficient goes down from 1.79 до 1.10.
Low values of the structural non-uniformity coefficient of the tested steel are suggestive of high uniformity of plate through-thickness structure.
