It retains an orthorhombic structure but demonstrates some degree of polar behavior compared to the α-phase
Notably, the introduction of water to the mixture led to the formation of a foam-like structure, as seen in Fig. 5
Consistent with the first experiment, adding water resulted in a foam-like structure, again shown in Fig. 5.
Foam-like structure of PVDF during both experiments.

Au nanosponges with tuned structures have also shown excellent optical properties and enhanced electronic fields in recent studies.
Figure . 5 (a) is the R6G SERS measured in an Au/Ag core-shell structure; (b) shows the linear regression curve of R6G.

As the great potential in biology, chemistry and medicine fields, microfluidics has developed into a new multidisciplinary research area including biology, chemistry, medicine, fluids, electronics, materials, mechanics et al.
There is some reference value to optimize the Bi-directional micro pump structure.
The resistance block M and the channel vessel wall of “H” structure filter introduced in Reference [2] constitute a unilateral structure of thick-walled orifice (L/d =2.5>2), given by Fig. 2.
Fig. 2 Structure and dimensions of the modified H filter There are some components realize their function using the characteristics of orifice structure formed by the sudden change of micro channel section.
The flow constringency in thin-walled structure causes that minimum section is out of orifice, and the flow constringency in thick-walled structure forms a negative pressure area in the orifice which can pump liquid in the channels.

Due to the excellent mechanical properties, ZrO2 was widely used as structural material in multi-industry, such as chemistry, power, biology, metallurgy and so on.
Thus, these ceramic-metal composites also play an important role in the structure materials, and it was so-called “cermets”.
Thus, ZrO2-Mo composite is a good candidate apllying in dunstry as structure matrials.
There might be some salt ions entering into the matrix due to the porous structure of composite.
So we thought that the composite had relative high corrosion resistant, even it showed porous structure.

The latter, a five-membered heterocycle comprising sulfur, is interesting because it has a kink or bend in the structure because of its structure.
In this work, we focus our studies on photoalignment properties of these materials in relation to their molecular structure.
Figure 1: Chemical structure of the azo containing thiophene based acrylates.
Summary In summary, our investigations show that the structure of the aligning materials is of vital importance for photoalignment of LC.

Influence on Structure and Composition of Carbon Supported PtCu-LaOx Composite Membrane Electrode by Acid Treatment Bin Yang1,a and Mingzhe Shen1 1School of Materials Science and Engineering, Kunming University of Science and Technology, 253 Xuefu Avenue, Kunming, Yunnan, 650093, China ayb0871@163.com Keywords: Structure, Composition, PtCu-LaOx, Acid treatment, Fuel Cells.
In our study, a new type of Pt/C membrane electrodes, PtCu-LaOx composite structure, on the surface of carbonaceous substrates was manufactured by Ion Beam Sputtering technology, and also was treated in different concentration H2SO4 solution.
It could be seen that Pt(111) and Pt(200) were main diffraction peak of PtCu-LaOx membrane, and could mean that the phase composition in these samples was all fcc crystal structure.
It was found in these samples that Cu had been alloyed with Pt, and that the phase composition was all fcc crystal structure, and that Pt(111) and Pt(200) were main diffraction peak.

In order to find ground state structures, we considered a large number of possible initial structures.
Then we optimized the geometric parameters of the ground state structures, the structures which appear without imaginary frequency and have the lowest energy are ground state structures.

The structure of the products was characterized by FTIR and 11B NMR.
The plane triangle structure is changed into regular tetrahedron and it will form semi-polar boron spiro structure[6].
It may be due to the free hydrogen in hydroxyl in the semi-polar boron spiro structure that takes a certain acidity[6].
