Abstract.
Mesoporous aluminophosphate molecular sieve (MAP), with an ordered structure consisting of alumino-oxygen tetrahedron and phosphor-oxygen tetrahedron, was first synthesized under a hydrothermal condition [3].
Results and Discussion Surface characterizations The catalyst materials were characterized for evaluating the morphology and structure.
Catalytic performance The materials thus characterized for structure and morphology were then used as catalysts to evaluate their catalytic efficiency.
Conclusions Results show that Cr-MAP molecular sieve has a mesoporous structure with long-range ordered crystal.

Spindle-like CdS structures were successfully synthesized via a simple one-step solvothermal process.
The mean center diameter of the spindle-like structure is about 200nm.
To 16h, the length and the diameter of the spindle-like structures were increased inconspicuously, but still could be found two or three elongated spindle-like structure connected together (Fig.3d).

Abstract.
SEM analysis showed that the catalytic paper had a porous structure originating from the layered fiber network, with Fe-pillared bentonite mostly embedded in the grooves along the axial direction of the carbon fibers.
ACFs and pulp fiber formed characteristic network structures and fine bentonite particles as the photocatalyst were scattered on the fiber matrix.
The network structure could adsorb orange II molecules and achieve high concentration of orange II near the Fe-pillared bentonite loaded on the carbon fibers.
SEM analysis indicated ACFs and pulp fibers formed a network structure with Fe-pillared bentonite mostly loaded on the grooves of ACFs.

Figure 3 shows the molecular structures of the salts used.
It is also observed two peaks of decomposition at 210ºC probably the loss of structure of C16 and 325 °C possibly referring to the C18 carbon chain, which exists in the structure of quaternary ammonium salt.
Apparently, the decomposition peak of the structure of the active material occurs at 260ºC.

Polarization and electric field characteristics were measured by Sawyer-Tower circuit and good hysteresis nature was formed for both structures of the films.
Ferroelectrics with perovskite structure(ABO3), such as lead titanate (PbTiO3), PbZrTiO3, PbLaTiO3 etc are the most studied ferroelectric oxides because of their versatile properties large piezoelectric-pyroelectric and large remanent polarization for use in thin film capacitors, electronic transducers, actuators, high-k dielectrics[5-6].
XRD analysis was carried out to examine the crystal structure and phase formation of hydrothermal synthesized lead titanate powders.
From SEM Photomicrograph, it was obvious that the altering solution chemistry was quite acceptable and appropriate for growth mechanism.
