Particular attention was devoted to synthesis and
processing routes, especially to mechanical alloying and mechano-chemistry, and to the
correlation between synthesis parameters and physical properties.

The cross-sectional structures of composite membranes were observed by scanning electron microscopy (SEM).
Moreover, XRD results revealed the crystal structure of PVDF.
This trend may be explained as follows: Layered structure of BBN is more advantageous to dissolve with PVDF and NMP according to their dissolved coefficient.
Fig.3 shows SEM micrographs of the cross-section structures of membranes M0, M1, M2, M3.

The aim of studies is to use computational chemistry methods to develop a mathematical model of log P for a number of monomers, model able to predict log P values for new chemical compounds before their synthesizing and testing.
The PM3 method was used regarding the semi empirical parameters used in the quantum calculations of molecular structures.
This set of structured data representing each molecule, was statistically correlated with the partition coefficient.
This can be achieved relatively easily with the aid of computational chemistry, which allows the identification of structural parameters which provides information on the changes induced by the presence and nature of the different chemical groups in the molecule.

Results and Discussion
The structure of LEG film is further characterized by a higher resolution TEM, Fig. 1(a).
At a higher magnification, the inset of Fig. 1(b) reveals randomly arranged and interconnected graphene flakes in the form of a 3D structure.
The presence of this intense band confirms an efficient restoration of sp2-domains (π-π conjugation) of the graphitic structure.
Surface inspection revealed that the deposition conditions assist CuNPs in anchoring on LEG surface without altering or blocking its porous structure.

The phase structure and phase
transition of Pb(Zr1-x(Ni1/3Nb2/3)xO3 (PZNN), where x = 0.0 ≤ x ≤ 0.50, were investigated.
It undergoes the AFE to a paraelectric (PE) phase and transforms from an orthorhombic structure to a cubic structure at 236°C [4].
Lead nickel niobate (Pb(Ni1/3Nb2/3)O3;PNN) has a perovskite structure and typical relaxor ferroelectric properties.
The crystal structure of PNN at room temperature is cubic (Pm3m), with a lattice parameter of 4.03 Å [9].
The columbite structure (NiNb2O6) was synthesized first.

The porous structure regularity for ONC is significantly determined by template structure, carbon precursor, synthetic procedure, process parameters and so on.
Finally, new porous structure will be formed in the porous channel of SBA-15 due to the partial carbonization of sucrose.
The morphology and structure of ONC was observed by a transmission electron microscopy JEOL JEM-2100 (TEM).
This may be due to the more condensed structure as discussed in the above XRD section.
