The AlN nanopowder is plasmachemically synthesized at the Institute of Inorganic Chemistry of the Latvian Academy of Sciences.
In addition, during the liquid-phase recrystallization, the yttrium oxide removes the oxygen impurity from the AlN structure, thus increasing the ceramics heat conductivity (Table 3).
The structure of the composites produced by pressureless sintering in a nitrogen atmosphere is the AlN ceramic matrix with uniformly distributed grains of molybdenum (Fig. 1) or another conductive second phase.

Synthesis, Characterization and Optical Property of KLaF4:Ce3+ Nano Particle Yanxia Han1, a, Qiannan Li2,b , Haiyun Shen3,c and Qiuhua Yang4,d 1Department of Chemistry, School of Science, Tianjin University, Tianjin, 300072, China ahan_yanxia@126.com, bqiannan2012@126.com, cshenhaiyun2006@163.com, dqiuhuay@tju.edu.cn Keywords: KLaF4:Ce3+, co-precipitation method, luminescent properties.
KLaF4 has two kinds of cubic and hexagonal structure just like NaYF4, but higher stability than NaYF4.
R Liu[10] has prepared a cubic phase KLaF4:Er3+/Yb3+ nanocrystalline and core-shell structure by thermal decomposition, which is demonstrated strong fluorescence emission.

Synthesis and Characterization of Silicone-modified Butyl Acrylate-Methyl Methacrylate Copolymer Latex Ye Han1,a, Xinwen Li1,b, Zhenguo Liu2,c, Huixuan Zhang1,2,d 1Changchun University of Technology, Changchun 130012, China 2 Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022 ahy@mail.ccut.edu.cn, blixw@mail.ccut.edu.cn, cliuzg@mail.ccut.edu.cn, dzhanghx@mail.ccut.edu.cn Keywords: Semi-continuous emulsion polymerization, D4, Low temperature resistance, Adhesive strength Abstract：Silicone-modified butyl acrylate-methyl methacrylate copolymer latex was prepared via semi-continuous emulsion polymerization.
When D4 content was 2.5wt%, the adhesive strength was the highest, which was ascribed to the crosslinking structure of copolymer hindering the movement of molecular chain and bankrupt in wetting and mutual diffusion.
Reasons were as followed: with increasing the content of D4, crosslinked and net-like structures were favored due to polycondensation of D4, which prevented molecular chain movement.

That is because the pressure required for pure hydrogen hydrate formation is very high( about 200MPa at temperature below 250K), but it is reduced after adding additive such as TBAB or THF, TBAB or THF molecules occupied the large-cage and stabilized the hydrate structure while H2 molecules occupied the small-cage, which will reduce the hydrate formation pressure dramatically.
For TBAB-H2 semic-hydrate, the cation is encaged into the large cavities, while the anion is combined with water molecule by hydrogen bonds and form cage, which can stabilize the hydrate structure[6,7].

It was probably because that red 2-hydroxy chalcone was generated by ring-opening reaction of the extraction of flavonoids. 2.2.2 Effect of temperature on dye stability Fig. 3 The effect of temperature on dye stability As shown in Fig. 3, with the increasing of temperature, the dye absorbance had little changes, which illustrated that semen litchi dye can keep stable at higher temperatures. 2.3 Extracts component analysis 2.3.1 Qualitative chemical analysis Table 3 The chemical analysis of semen litchi extract Analysis Method Experimental phenomena Tannins 1% FeCl3 solution dark green precipitate gelatin solution precipitate Flavonoids 1% AlCl3 solution yellowish-brown precipitate ethanol of 1% FeCl3 the color of dark green 2.3.2 Infrared spectroscopic analysis Fig. 4 The infrared spectrum of semen litchi extract Tannins and flavones are both natural polyphenols with common molecular structure containing hydroxyl, ester, aromatic ring and glycosidic bond [6].
The effect of the dye bath pH was attributed to the correlation between dye structure and silk fabric.

These investigations will allow one to produce one-electron logic structure and spin-information systems using an electron spin as a memory cell: one spin – one information bit.
The origin of the ferromagnetism in diluted magnetic semiconductors has been investigated using the first-principles calculation of electronic structure in works [10].

Our method reported here differs conceptually from all previous methods of forming porous films, it exploits a duplication of the structure of porous alumina template.
The crystal structure of the porous films was examined by XRD.

The grain structure of film can be seen clearly from this AFM image.
We conclude that the optimum layers coated on glass substrate were 12 layers with exhibit the lowest emission peak which due to the lowest crystalline structure.
