Experimental results show that the electrochemical activity of the PBrT/WO3 nanocomposite films was significantly improved due to the contribution of unique structure and interactions between PBrT andWO3[2].
Conducting polymers, being a family of important electrochromic materials, have gained popularity due to their unique advantages, such as good processibility, high optical contrast, flexibility for large-area application and the ability to modify their structure to create multicolor electrochrome[3].

Most of the work should be finished manually, which would affect the accuracy of the results and limit the operating efficiency of the experiment, and which can’t meet the requirements of modern analytical chemistry for complex samples, such as speediness, briefness and accuracy[10].

X-ray studies show that after annealing in H2 at 973 K and above the crystal structure of the surface, which is in direct contact with the surrounding environment changes.
process in the reducing environment starts with the formation of free polarons at T = 870 K; further temperature increase leads to the point defects concentration increase thus process of bipolarons formation begins; - cooling of the LN congruent sample from the T = 870 K leads to the bipolarons formation; calculated energy of bipolaron association is about 0.3 eV; - the AA resulting spectrum at Tr consists of three bands and in general has a similar shape after annealing in vacuum, H2, H2O vapour and Ar: band with a maximum at the 350...400 nm is most likely caused by the F-type centers, 500...520 nm – bipolaron absorption, 700...800 nm – absorption of coupled polarons; - annealing of LN in H2 leads to the more intensive coloration comparing to annealing in other environments; lowest intensity spectrum is after annealing in H2O-vapor; - coloration process is caused by diffusion, which is anisotropic; - annealing of LN in H2 at T > 973 K leads to the formation of layer with LiNb3O8 structure

Many learning subjects are based on experimental courses, especially for some of the practical disciplines, such as physics, chemistry, etc., but at present,[1-3] due to the limitations of the experimental conditions, such as the lack of laboratory equipment, laboratory equipment difficult to operate, precision instruments easy to damage, lack of access to experimental time-consuming and money, making the students experiment practice, resulting in some teaching experiments cannot be properly opened, plus some abstract experiments cannot be realized in real physical scene, such as nuclear fission, which hinder the students' practical ability.

Moreover, the method of manufacturing such ceramics can be effectively employed to control the size and shape of MEMS devices, as well as material properties through tailoring the chemistry of the organic precursors.
It offers temporal and spatial control of the formation and allows processing at ambient conditions, and also can easily obtain free-standing polymer structure with low cost.
Many studies reported in literature deal with the photo polymerization kinetics of thiol-ene systems [3~5], but none studied the thiol compound copolymerized with double bond in hyper branched structure.

Relationship between solution treatment time and microhardness of different areas It is well known that the solution treatment of HNSS can dissolve carbides and nitrides in the matrix to obtain a uniform structure for subsequent processing [17,18].
Both elements are depleted at the ferrite-austenite/austenite-austenite boundaries, and especially from the banded ferrite phase because Cr is a ferrite stabilizing element, and the structure tends towards austenite during solution treatment [16].

Introduction The indole ring widely distributes in nature as one of the most important heterocycles. [1] 4-Azaindole, which has a similar structure to indole, but with a nitrogen atom taking the place of C-4 in the benzene ring, has utilized as a key structure in biological and medicinal chemistry. [2–9] For example, the 2,3-bis(het)aryl-4-azaindole derivatives have shown inhibition of the kinases RAF-1 and DYRK1A. [10] The 4-azaindole bisphosphonate derivatives were reported to treat and prevent disorders associated with abnormal calcium and phosphate metabolism in bone and joint diseases. 4-Azaindole was first prepared by Kruber in 1943.[11] To date, one of the most commonly used method for the preparation of 4-azainole was the same as those for indoles including the Madelung-type cyclization, [12] a Reissert-type procedure, [13–16] the Leimgruber-Batcho reaction, [17,18] and a Lorenz-type cyclization. [18,19] Recently, several groups have utilized a reductive cyclization methodology
