Reactive synthesis of TiAl/Ti5Si3 in situ composites Jianfeng Zhu a, Wenwen Yang, and Shaodan Li Key Laboratory of Auxiliary Chemistry & Technology for Chemical Industry, Ministry of Education, Shaanxi University of Science and Technology, Xi'an 710021, China a zhujf@sust.edu.cn Keywords: TiAl, Ti5Si3, composite, reaction synthesis Abstract.
With respect to address these issues, it is anticipated that a unique structure will be produced with in situ formed Ti5Si3 and Ti3Al distributed in TiAl matrix.
The former offers the coarse grain sized, but the latter has the fine duplex structure of the lamellar phase of α2 (Ti3Al) and colonies equiaxed γ (TiAl) phase.
Fig. 4 (d) shows the α2 (Ti3Al) lamellar structure, which is also beneficial for improving the TiAl based materials.
A unique structure was produced with in situ formed Ti5Si3 and Ti3Al distributed uniformly in γ-TiAl matrix.

These hollow HAP microspheres with such structures may be useful as devices for drug delivery.
The XRD patterns of the dried and reacted powder showed no distinct peaks, with only a broad background indicating a non-crystalline structure.
LCB glass microsphere was proved to be good precursor for hollow HAP microspheres and the resulting microspheres possessed good hollow structures.
These hollow HAP microspheres with the structures may be useful as potential drug-delivery medium.

Lignin surrounds hemicellulose and cellulose to form a more complex structure where lignin acts as barrier layer around both components.
In order to get high sugar yield for biohydrogen production, the structure of EFB need to be examined.
The morphology of the samples was observed under Scanning Electron Microscope, SEM model Philips XL30 to study the fiber structure.
High lignin content in whole native sample might be due to incomplete acid hydrolysis in EFB fibers because inaccessibility of acid to cellulose in complex structure.
The structure looks very rigid and solid because the surface of the fiber is covered by a layer of matrix material like lignin or waxes [3].

Mechanical Properties It is common knowledge that mechanical properties are very structure-sensitive ones and that it is not so easy to prepare the representative samples for detailed study.
The second one is often connected with the presence of the clearly defined columnar structure.
The structure of these films is characterized by a negligible dislocation network coupled with only one film/substrate interface.

Since the inorganic component of bone is not stoichiometric HA but CO3Ap that contains up to 8 wt% of carbonate in the apatitic structure [11], CO3Ap appears to be an excellent candidate for the bone substitute material.
The interconnected structure was observed (Fig. 3 a).
However, the void structure is found in the micropore of struts. 250 µm 25 µm (a) (b) Fig. 3 SEM image of α-TCP foam specimen after coating with CO3Ap/PCL showing the interconnected structure (a) and a void structure (b) 3.2 Cell attachment Cell attachment is the primary process to ensure a successful osteointergration when implant [15].
As previously reported, the implant’s surface properties and surface chemistry influence the cell response at the cell–material interface, ultimately affecting the rate and quality of new tissue formation [6,17].
Conclusions Coating CO3Ap/PCL on the α-TCP foam not only maintained the interconnected structure but also improved the biological activity of the α-TCP foam.

After impregnation with Fe, the X-ray diffraction profiles were almost unchanged, exhibiting the high diffraction peaks at low angles, indicating that SBA-15 still retained the ordered structure (Figure 2) [10].
It can be observed that the samples under study had high levels of silica (SiO2), given that the structure of the SBA-15 molecular sieve consists solely of silica.
The specific area and total specific pore volume of the calcined SBA-15 molecular sieve given in Table 2 are typical of SBA-15 structures synthesized under similar conditions, as reported elsewhere [7,12].
Conclusion According to XRD, BET, and EDX results, the SBA-15 support has a structure that includes multi-level mesopores, crystallites, and grains within the original particles.
