Abstract.
These experiments indicate that under laser exposure investigated nanocomposite became in a new state (Figure 2), which has a different photoinduced absorption coefficient due to agglomeration of CdS quantum dots in larger structures.
As was noted above, light at the wavelength λ = 633 nm does not modify the structure of the nanocomposite and has no effect on the optical properties of the sample.

A study of the luminescence of rare earth solid state materials is an interesting research field in
both rare earth physics and chemistry [9-10].
Fig.1 Preparation procedure of Nd1.6Eu0.4Zr2O7 nanocrystals by SACM 2) Instrumentation The crystalline phase structure was determined by Bruker D8 Advance X-ray diffractometer (XRD) using Cu Kα radiation.
Raman spectroscopy is a very useful tool for the study of bond length and angle between cation and anion in the average lattice, structural phase transitions and in determing phases and structure of multioxide systems [17].

Abstract.
Thanks to pore size distribution curves it is evident than pore structure of arenaceous marlstones is really different.
Also this characteristic is considerably dependent on pore structure, but in the case of water vapour diffusion resistance factor it is negatively correlated.

Introduction
Cement-based material is the most universal used material for concrete construction, but its relatively low mechanical strength and fracture toughness hardly meet the increasing requirements of superior properties of concrete structures under extremely complicated conditions just like earthquake, gust loading, blast stress [1].
Nanosize materials possess many outstanding properties in physics, or chemistry otherwise from those of macro-size, or micro-size ones.
Multi-walled carbon nanotube (MWCT), made of rolled several layers of carbon graphite, possess the quasi one-dimensional nano-structures (of some μm length, some nm diameter) [4], the nanotube has extraordinary mechanical properties, extremely high electrical/thermal conductivity, unique optical/magnetic properties, which has been widely used as high strength but light fiber, one-dimensional quantum lead with radial limited range, nano-electronic parts of an apparatus, and near-field emission material [5].

Abstract.
The performance tested in different time was shown in Table 6 and Table 7.It can be concluded that antistatic agent synthesized could be used in polyurethane seal materials for its good conductive property and molecular structure.
It formed the surface structure like the Fig. 1(e) after processing and drying.
