Introduction Lead Titanate Zirconate (PZT) is typically ferroelectric ceramics materials characterized by the ability to convert electrical signals into mechanical vibrations, and vice versa, due to the presence of electric dipoles in its structure [1].
The PZT molar ratio of 53/47 (Zr/Ti) exhibits high dielectric constant, piezoelectric and electromechanical properties [2] due the large number of possible directions of the spontaneous polarization present in its structure.

The dynamic mechanical analysis was introduced to prove the film structure.
DMA test further indicated that blends films were phase separated structure and can considered as phase separation blends involving a soft phase filled with hard spheres.

Under the background of creating Oriental leisure capital, the continuing expansion and update of Hangzhou and the internal demand of adjustment and upgrading of industrial structure optimization make the industrial heritage protection and development in Hangzhou along the canal become an important part of the organic update of Hangzhou development increasingly.
Until 1980s, industrial districts of light chemistry and Gongchen bridge textile industry districts were gradually formed along the Hangzhou Canal (Figure 1), inside of which the industrial occupancy depending on water transport is closely next to the affiliated dwellings for the worker.
In the restoring process, the functional space is open, and the surrounding related structures, facilities and the depended landscape elements which indicate the feature of industry development are retained.

It makes difficult to use them in the production of thin-walled and high-reinforced structures, monolithic floors, application of finishing and protective coatings and repairing of roads.
To improve the workability of the concrete mix and obtain a polymer concrete with a homogeneous structure and high strength, it is recommended to use chlor-paraffin ChP-470A and “Lukoil” engine oil as a plasticizer.
It makes difficult to use them in the forming of thin-walled and high-reinforced structures, monolithic floors production, application of finishing and protective coatings and repairing of roads [14-16].

Introduction Copper nitride (Cu3N) in cubic anti-ReO3 structure (space group Pm3m) is a fascinating nontoxic and stable material at room temperature in air [1].
XRD pattern of sample 1 means as-deposited films are belong to cubic-ReO3 structure of Cu3N with a strong preferred [111] orientation.

In addition, the structure difference in the homologues acetate seems having no effect on the stability and release behavior of curcumin, while the investigated properties clearly depend on the ME/acetate ratio in the microemulsions.
It is well known, microemulsions are thermodynamically stable and macroscopically homogeneous; however, the structure is heterogeneous on a microscopic scale.
Conductivity is a structure-sensitive property of solutions and is frequently used to investigate the structure and structural changes of microemulsions.
In order to understand whether the oil structure dominantly influence the microemulsion release behavior, the phase diagrams of three more systems, by replacing ethyl acetate with butyl acetate，n-amyl acetate and n-octyl acetate respectively, were determined.
Summary The work demonstrates that the Brij97/isopropyl alcohol/ethyl acetate/H2O system forms a microemulsion single-phase, which spanning the range of possible structures from W/O and O/W droplets to a bicontinuous structure.

Using the methods of X-ray phase analysis, spectrography and metallography, the composition and structure of coatings were determined, the microhardness distribution over the coating thickness was studied.

The alloy was processed in three subsequent steps: 1) casting and homogenization, 2) extrusion, and 3) cold rolling and heat treatment to obtain a recrystallized grain structure.
The three subsequent processing steps of the alloy were 1) casting and homogenization, 2) extrusion, and 3) cold rolling and heat treatment to obtain a recrystallized grain structure.
The polished specimens were also anodized at room temperature for 2 min using HBF4 to reveal the grain structure.
Results and discussion As seen from Fig. 1, all three materials exhibit an equi-axed grain structure.

In this research we propose a portable system designed as a structure created by 3D printing of thermoplastic materials and composite materials.
Inside of this structure, optimized as an assembly space, the electronic system is designed for guidance and warning actions adapted to the patient with low vision.
Block diagram of sensorial system In the system's operating structure, the DC source (an external battery) feeds the Arduino Uno plate.
The rapid prototyping method (3D printing) has been the major advantage of building such a system by making it possible to create a small, easy to assemble and usable structure with the appropriate chromaticity and adaptability to any anthropometric dimensions.
