Introduction
The application of advanced materials in aircraft and automotive industries enables to enhance properties of integral structures in airframes, body frames and engines and reduce their weight and cost.
However, components made of different materials need to be someway joined or welded and the joints of two different materials produce local changes of properties, chemistry and microstructure in heat-affected zones (HAZ).
All this possible events as well as existence of residual stresses at the interface and/or in the end-member of the joints need to be considered in design of components and structures.

The TGA profiles of PLA/PANI NF and PLA/P(ANI-co-m-ABA) (60/40) NF were similar, which was expected because the polymers are not very different in structure.
This is due to rapid solidification of the NF retarding the growing crystalline structure in the NF.

It indicated that the kind of the adsorption isotherm is a typicall IV Brunauer-Emmett-Teller, a typical adsorption hysteresis appeared when P/P0=0.6~0.95, and the pore size was 1.099nm, it means that the catalyst contains good pore structure which could provide many catalytic site for the reaction [9].

As shown in Fig. 1, the crystal structure clearly shows that the pyridine group and coumarin dye was conjugated with the divinylbenzene linker.
Such conjugated structure facilitates the electron transfer between the coumarin dye and pyridine group.

LDHs are well known for their anionic exchange properties and their stable structure.
The structures of samples were determined by X-ray diffraction (XRD) using a Rigaku D/max 2000/PC diffractometer with Cu Kα radiation (λ = 1.5406Å, scan rate 0.02°/s).

Abstract.
The sample showed a typical fine eutectic structure with interphase spacings on a submicron scale, as shown in Fig. 5.
The co-precipitation of two phases of YAG and Al2O3 resulted in a homogeneous eutectic structure.
