The microstructure
of TiO2 nanowire made from mixtures of 75% of anatase structured particles and 25% of rutile
structured particles showed rutile structure by XRD.
These two structure particles used as a raw material to synthesize TiO2 nanowire.
The other hand, Fig.2 has a rutile structure and has no peaks of other impurities, such as NaCl and Na2TiO3.
This unscrolling phenomenon was accompanied by a phase transition, resulting in nanosheets with the rutile structure.
These can be explained by surface chemistry.

The reveal of the as-cast grain structure by an optical microscope (OM) indicates that the high Zn content reduces grain sizes considerably.
Fig.1 presents the optical micrographs revealing the grain structures of the three alloys.
This observation implies that the addition of Zn addition leads to a fine grain structure in the Zn-containing.
Optical micrographs showing grain structures of SC (a) Mg-1.0Zn, (b) Mg-5.0Zn and (c) Mg-10.0Zn alloys, respectively.

Characterization of the thermo-gravimetric analysis, differential scanning calorimetry (DSC) indicated that much more residual char with intumescent structure, the incombustible gas and water were formed during combustion of flame retardant polyester fabric, whose decomposition temperature was lower compared to that of the untreated sample.

Planar defects, which are aligned along {100} crystallographic planes of the perovskite
structure, form with time.
Many of these materials, which primarily reveal the perovskite crystal structure, exhibit the property of high proton conductivity at moderate temperatures.
However, a final conclusion about the local chemistry and the corresponding formation mechanism cannot be drawn as yet.

Structure and properties of the nanocomposite films were measured with FTIR, SEM, XPS and
DMTA.
Introduction The blending of different sorts of materials produces composite structure, which can combine different material properties, or may reveal novel properties not existing in the constituent phases [1-3].
Poly(amic acid)/BaTiO3 nanocomposite solution was prepared by directly mixing of poly(amic acid) solution and BaTiO3 nanoparticles with a typical perovskite structure and a diameter of about 30 ~ 70 nm under the mechanical stirring and ultrasonic wave irradiation.
The nanoparticles and clusters coalesced into more uniform structure at a higher BaTiO3 concentration than at a lower one.
The εIE of the polyimide and nanocomposite films was intensively affected by the structure regularity of polyimide main chain.

The tight texture structure and the well-stretched monofilament surfaces of the MPF fabrics retard the grafting to a great extent.
In fact, the grafting morphology was strongly related with substrate structure [5].
As a trifunctional monomer may also modify the polymerization kinetics and, by forming branched and compact structures, promote precipitation and high local concentration of the growing polymers at the surface.
Therefore, the tier layer structure of SMS seems to promote the grafting copolymerization.
The inner fine and soft fiber layer of tier layer structure of SMS nonwovens demonstrate high grafting propensity.
