The review and research papers presented in this volume may be subdivided into three aims:
(i) the investigation and modelling of interfacial structure (ii) efforts to correlate structure/property relationships and (iii) phenomenological descriptions of particular interfacial properties The conference focussed on four objectives: 1.Grain Boundaries Structure and Properties 2.Dynamical and Mechanical Properties 3.Heterophase Interfaces 4.Electrical Properties and Superconductors.

Thus, the obtained data allow predicting operating parameters of the electrolysis to obtain copper - cadmium oxide system of a predetermined porous structure.
Significant changes in the nature of porous structure occur during heat treatment.

The functionalization on the meso positions endows this type of compound a brighter perspective in synthetic chemistry.
In all cases, the symmetry of tripyrrane or tripyrrin structure had been disrupted.
Scheme 1 The synthesis of bis-(5,10-diphenyltripyrrin)nickel(II) 5 Fig. 2 The crystal structure of 5 (H atoms were eliminated for clarity) The crystal structure of 5 is shown in Fig. 2.
Fig. 3 shows the details of the distortion in one of the two tripyrrin structures.
The synthesis of 5 provides a new model in the tripyrrin synthesis, providing a brighter perspective for tripyrrins in synthetic chemistry.

Several substitutions have been made in the KTP structure with the intention to understand its unusual properties owing to the ability of this structure to accept the insertion of different cations.
Results The polar structure was first refined as KTP without dopants.
Nb and Sb cations enter the different crystallographic positions in the structure (the Ti(1) and Ti(2) sites, respectively).

The thermal chemistry behavior of the as-prepared nano-Ni/B composite particles was better than superfine boron powders.
In addition, the micro structure and the thermal chemistry behavior of nano-Ni/B composite particles were characterized by SEM, XRD and TG-DTA.
The thermal chemistry behavior of the samples was measured by DTA and TG using the analyzer of TG-DTA-DSC (Beijing Henven Instrument HCT-2).
Nano-Ni particle with high purity is a spheroid of face-centered cubic crystalline structure with an average diameter of 21.7 nm.
Thermal chemistry behavior of the as-prepared nano-Ni/B composite particles is better than the uncoated boron particles.

Keywords: phthalates, nanofiltration, adsorption, humic acid, nature organic matter.
The humic acid (HA) added in the simulated water increased the adsorption of PAEs on NF90 but decreased that on NF70, and the ions (K+, Ca2+) added in the simulated water affected the adsorption by influencing membrane structure, HA structure and interaction between membrane and HA, and the same result was obtained in the river water.
Introduction Nanofiltration(NF) can efficiently remove organic contaminants by adsorption, size exclusion and charge repulsion[1], and it can be governed by many factors including membrane characteristics, physicochemical properties of the solutes, and solution chemistry[2, 3].
For this, the DCHP’s special cubic structure play a role, the least water solubility (0.24mg/L) is a proof.
The adsorption of PAEs on NF70 and NF90 membrane strongly dependent on the solution chemistry including pH, ionic strength and organic matters.
