Infrared spectroscopy has been used to investigate the chemical structure of polymers.
Structure and water sorption of polyurethane nanocomposites based on organic and inorganic components.

Instruction TiO2 is the most potential photocatalyst because of its stable chemistry properties, non - toxic and low cost [1,2,3].
The structure properties were characterized by a SIEMENS D-500 X-ray diffractometer with a CuK wavelength of 0.154 18 nm.
It indicates that the doping of Ag can pomote the growth of anatase phase and can not change the crystal structure of TiO2.

These problems are probably due to the β - alumina (NaAl11O17) type structure with high ionic conductivity.
New phosphors with a rigid crystal structure should be designed.

Results and discussion Structure characterization of the products.
No phases corresponding to compounds of Eu and Lu were found, which illuminated that Eu3+, Lu3+ were successfully doped into the lattices of the host structure.

Phase structure of the sample was analyzed using X-ray diffraction (XRD) patterns recorded on a PHILIPS X’pert Pro X-ray diffractometer with CuKa radiation (l = 1.546 Å).
However, one can see from Fig. 2(b) for XRD patterns over a 2θ range of 40° -52° at 0.05°/s that the peaks near (031), (113), (032) and (123) planes are spitted for t>12h, which show that Ag2Se begin to form texture structure.

The structure of the prepared composite was examined by FE-TEM and FE-SEM according to a method described by Oh et al. (2006) [3].
One example of the composite is a structure in which nanosized Ag particles formed from Ag ion and silica molecules formed from silicate is, individually or together, surrounded by water-soluble polymer via exposure to radioactive rays.

Sow 1,2, 1Department of Physics, Blk S12, Faculty of Science, NUS, 2 Science Drive 3, Singapore 117542; 2National University of Singapore Nanoscience and Nanotechnology Initiative, 2 Science Drive 3, Singapore 117542; 3Department of Chemistry, Faculty of Science, NUS, 3 Science Drive 3, Singapore 117543 We present the applications of optical tweezers to manipulate and assemble CuxS dendrites in fluidic medium.
One of the challenges faced by incorporating micro/nanostructures into devices is to be able to control their motion and position, and further to manipulate and arrange the structures into desired formations or patterns.
Optical manipulation in conjunction with a patterned substrate would achieve even better assembly of the dendrite since the dendrite would be confined to the patterned structures on the substrate.

Interface electrostatic force and ion diffusing or motion provide requirement for the physical chemistry reaction of the interface joining.
Because of the symmetry of the sample structure, a quarter of each sample was analyzed.
Because of the symmetry of the three-layer structure, it can be seen that the entire deformation of the sample is much smaller than that of the two-layer sample.
