Ongoing research aims to replace the copper wick structures with high conductive CNT wick structures [6].
Fig. 1 Sintered copper in CNT The resulting structure had a volumetric porosity of 50%.
An additional novel wet chemistry method used to create silver nanoparticles took advantage of D-glucose as a reducing sugar and a starch as the stabilizer and also cellulose molecular chain is applied to employ the reducing and stabilizing features of cellulose to synthesize nanosilver..
Because the wick is a capillary structure comprising carbon nanotubes this ensures that vaporized operating fluid is condensed fast.

Molecular weight determination The effects of oxypropylation reaction on Kraft lignin structure were evaluated by using changes in molecular weight.
This result reveals that Kraft lignin is stable at high temperature, which is attributed to the high degree of branching and formation of highly condensed aromatic structure for both types of lignins.
The second thermal degradation at about 280 °C is characterized by the weight loss of hemicelluloses that are attached to the lignin structure [11].

The structure of the metal welded bellow seal is given as the Fig1.
In order to improve the life-span and durability of the metal welded bellow, the structure of the bellow wave should be improved.
The stress, strain and displacement were analyzed by comparing the V and S wave structure of welded bellows seals.
Numerical Model for Shape Optimization Reaction-diffusion model was firstly proposed by Turing and has been studied in various fields, such as chemistry and biology.
This is indicated that the stress concentration largely reduced and the optimized structure close to uniform stress distribution form.

The pyrolytic carbon shows four forms with a different polycrystalline structure: isotropic, low textured, medium textured and high textured [1].
The pyrolytic carbon matrix around the fibers has a cylindrically layered structure and each layer may have different coefficients of thermal expansion in the axial, radial and circumferential directions, i.e., it is anisotropic.
The number of layers, their width, order and structure are influenced by the deposition parameters.

Introduction Since conventional phosphate glass has hygroscopic property and poor chemical durability owing to the glass structure, its application was limited.
Also for a comparative experiment, we used a product that was fabricated by factory Result & Discussion According to the amount of network modifier oxides, phosphate glass has two types of structure: network structure and polymeric chain structure, and both are different from silicate glass.
When increasing the network modifier oxide, phosphate glass tends to form polymeric chain structure.
From Figs. 3 and 4, therefore, we know that the dissolved amount of K ion and Ca ion depend on the quantity of K2O It is considered that 4 Title of Publication (to be inserted by the publisher) dissolution velocity increased because the glass structure substitute (-O-)P-O-Ca for (-O-)P-O-••••K+ when the quantity of K2O increases.

Breathers with a rigid type of non-linearity exist in pure metals with FCC –, BCC –, and HCP – structures.
Alloys of A3B stoichiometry with L12 superlattice structure are the most numerous ones.
Searching the currently known systems having L12 structure made it possible to identify about 190 of such phases in the field of A3B composition.
Alloys with L12 structure form the development basis of currently existing superalloys.
In computational chemistry, the embedded atom model is applied for approximate description of two atoms interaction energy.

Incremental Regressive Learning Algorithm of Support Vector Machine and its Application Shihua Zhang1,a, Xilong Qu2,b and Xueye Wang3,c 1Network Information Center, Hunan Institute of Engineering, Hunan, 411104, China 2School of Computer and Communication, Hunan Institute of Engineering, Hunan, 411104, China 3College of Chemistry, Xiangtan University, Hunan, 411105, China ashihua_zh@yahoo.com.cn,b42559003@qq.com Key words: Incremental Learning; SVM (support vector machine); estimation of regression; ANNs regression; Abstract.
The main advantage of SVM is that it adopts the structure risk minimization (SRM) principle, which has been shown to be superior to the traditional empirical risk minimization (ERM) principle, employed by conventional neural networks.
(ii) We showed that using the ISVM methodology we can have a reliable prediction compared to the simple structure of a linear model and complex model ANNs.

Modification of the glass structure is affected by decreasing the number of Si-O bridges and the connectivity of the network [2].
It was well known that Raman spectroscopy was a powerful tool for the analysis the archaeological glasses both for surface weathering study and bulk structure characterization [2, 6].
SEM-EDS The precious study on the structures of the glass samples showed some agglomerations of various microstructures, as shown in Fig. 1.
In the spectra of the studied glass fragments, the strong band appears at around 1000 cm-1, which is characteristic of the structures with isolated and poorly connected tetrahedral, observed in any glassy network containing a large amount of PbO.

Since then a significant improvement has been recorded in terms of surface structure, hardness and wear resistance [1].
The surface structures of the track produced at different glazing speeds revealed that all the surfaces are fairly smooth with defect free surfaces.
This explanation is also supported by metallographic evidence with a higher dendritic structure in the melt pool layer shown in Fig 3 (a).
The elemental analysis of this dendritic structure (Fig. 3 (d) gave mainly Ti and C.
