This article analyzes the two synthetic approaches we have developed for the syn- thesis of 1- (2-pyridyl) isoquinolines with different substituents in the C3 and C4 po- sitions, which are of interest, in particular, as ligands for transition metal cations [5], as well as from the point of view of creat- ing OLED [6].

summary:
  2 shows the dependence of the photo-response of PbSe films from the time they were annealed at temperatures of 648, 673 and 698 K. Dependencies have pronounced maximum of response, which with increasing temperature shifts toward shorter annealing. It is found that the decrease in crystallite sizes, which form PbSe films, contributes to a signifi- cant increase in the level of its photore- sponse.

Its expression is observed for the system under study with an increase in the magnitude of anode current density from 0.5 A/cm2 (Fig. 1b), at that the transition times are from 2 ms to 10–15 s. Chronopotentiometry at platinum electrode in KF-NaF-AlF 3 -Al 2 O 3 melt 192 № 3 | 2015 Chimica Techno Acta Analysis of curves of change in the platinum potential under current inter- ruption points indicates a long period of term relaxation of the platinum potential as after the anode current density pulse of value of 30 mA/cm2 (30–35 s), so after pulses of value of 0.5–2.0 A/cm2 (10–15 s).

  Measurements have shown that the electrical conductivity of zinc-rich coatings containing electrolytic zinc powder, not inferior to the conductivity of the film with powder PZHD-0 obtained by the method of evaporation-condensation, despite the sig- nificant difference in the amount of zinc pigment. On the basis of the received data we can conclude that the use of electrolytic zinc powder as a pigment will significantly save zinc.

  Yttrium ferrite quenched from high temperature within the entire range (1173 – 1473 K) or slowly cooled to RT possesses ortho- rhombically distorted perovskite structure, which is in good agreement with the results reported earlier [1-4]. Fig. 1 illustrates XRD patterns of YFeO3 prepared at vari- ous conditions and evaluated values of unit cell parame- ters, as an example. Since YСоO3 is only stable below 1266 K, it is likely that a continuous series of YFe1-xCoxO3 solid solutions cannot be obtained at higher temperatures.

  Similar shifts of  the  absorp- tion bands of  C=O bonds in  IR spectra were previously observed during the in- teraction of ivy triterpene glycosides with Chol [12], as well as during the formation of GA and GC complexes [11]. These facts may indi- cate the presence of hydrophobic contacts between Chol and GC molecules.

summary:
  As  for the  film of  individual lead sulfide and solid solutions films based on PbS, elastic compressive stresses are cre- ated in them, that evidenced by the nega- tive temperature dependences σ = f (T) in Fig. 4. The  absolute value of  mechani- cal stresses of  these films increases with an increasing the annealing temperature from 350 to  893  K.  Compressive stress- es rise in absolute terms from about 200 to 1200 kN/m2 for PbS and from 150–250 to 2000–2750 kN/m2 for CdxPb1−xS under these conditions.

  Synthesis of highly stable luminescent molecular crystals based on (E)-2-((3-(ethoxycarbonyl)-5-methyl-4-phenylthiophen-2-yl)amino)-4-oxo-4-(p-tolyl)but-2-enoic acid

summary:
  Generally, organic crystals (OCs) are based on organic molecules packed in a specific order, where weak intermolecular interactions maintain the integrity of the crystal structure. This organic compound was then utilized to create new organic molecular crystals in the form of single microcrystals and large scale thin films demonstrating highly efficient and stable photolumi- nescence at ambient conditions.

Pene- tration of liquid metal along the grain boundaries sharply reduces the strength characteristics of the latter [6–9].

  New possibilities of the functionalization of 6-hydrazino-1,3-dimethyluracils: one-pot synthesis of 5,7-dimethylpyrazolopyrimidine-4,6-dione and 1,3-dimethyl-5-arylidenebarbituric acid derivatives

summary:
  It is known that pyrazolopyrimidine derivatives have a wide spectrum of biological activity, including antimicrobial[1, 2, 3], antivi- ral[4, 5], anti-inflammatory and etc. We found that heating hydrazones 2а-c in TFA gave 5,7-dimethylpyrazolopyrimidine-4,6-diones 3а-c and 5- benzylidene-1,3-dimethylpyrimidine-2,4,6-trione deriva- tives 4а-c. Considering the literature data, it can be as- sumed that the formation of pyrazolopyrimidines 3a-c occurs through the 5-trifluoroacyl intermediate A. The formation of intermediate A occurs as a result of acylation of the starting hydrazones 2a-c of TFA.

summary:
  Similarly, carbon nanotubes with different morphologies (single-walled and multi-walled carbon nanotubes (MWNTs)) can be produced by varying differ- ent catalysts and process parameters. A decrease in specific surface area, similarly associ- ated with the oxidation of carbon nanotubes, was also ob- served.

summary:
  On the other hand, using geometrical- topological method (bond-valence site energy modeling, BVSE), and density functional theory (DFT) calculations, we demonstrated that Mn ions form MnO6 clusters, which are preferably linked in dense layers in Li1.3Nb0.3Mn0.4O2, and negatively affects lithium diffusion The decrease in the state of charge can be explained by a partial reduction of Mn ions during synthesis.
