Abstract.
This change in chemical structure is responsible for a whole range of different physicochemical properties, which are mainly caused by the presence of sulphur – sulphur interactions incurring conformational rearrangements of EDTT repeat units [5].
Increase of g-factor value with applied potential is caused by several factors, such as changes in energetic structure, magnetic environment and gradual increase of spin density on sulphur atom with progressive doping.

Looking forward to the heterojunction structure is helpful to the catalyst's stability, and at the same time has a good sensitization effect.
Summary The phthalocyanine sensitized nanowires TiO2 visible catalyst was prepared by in-situ hydrothermal, and we obtained a series of conclusions in experiment: by controlling the amount of CoPcTs, the growth of TiO2 and the adsorption of sensitizer is synchronous under the hydrothermal condition, which induce to interpenetrating structure; verified the phthalocyanine sensitization nano-TiO2 photo catalytic ability in degradation experiment of MO solution; methyl orange was degraded in different visible light, thus, we can indicate sensitization effect of the MO degradation results from CoPcTs in visible light.

MLCC is fabricated by laminating dielectric layers and internal electrodes alternately and then
co-fired to form the monolithic structure.
We investigate the structure and dielectric properties of this low-temperature sintered ceramics and make a comparison of the two doping methods.
The defect chemistry equation is written as: B2O3 → 2 Bi⋅⋅⋅ + 3OO X + 3 VBa" (2) When doped as powder, ZnO-B2O3 tends to serve as flux material and form liquid phase [3].

One of the methods used to develop Mg is to make a magnesium composite structure [2].
Composite structures are considered to be more flexible in terms of control of the component design, the use of reinforcing powder, and biocompatibility [4, 5].

Demand from the electronic industry for thick and thin film of magnetic ceramics has dramatically increased, and novel device designs based on the availability of 2-D magnetic structures are continuously being developed.
The structure of dried films was investigated by SEM (STEREOSCAN 360, Cambridge Instruments) and X-ray Diffraction (BRUKER D8 ADVANCE).
Improving the results as to reliable control of the deposition process, film thickness and texture control and post-deposition processing needs further insight on the physics and chemistry of the EPD process from ethanol-diluted DEG/magnetic nanoparticle suspensions, which presents many non-standard aspects.
