Interestingly, the conductivity of LiTaO3 is about the same as pure MEH-PPV but the charged species and the structure of the materials are different.
This emphasizes the effect of the type of conducting species as well as the structure of the material medium under consideration.
It can be applied to different types of conducting species as well as different types of materials with different structures.

The results of density measurements are shown in Table 1 and show that the variations in the density correspond to changes in the structure as observed either by microscopy or by X-ray diffraction.
The heat treatment for prolonged time (8 hours) without the magnetic field leads to precipitation of the nonmagnetic phase as well; this phase has a complex peak structure and it seems that the diffraction pattern of the magnetic phase gets buried in its complex pattern.
The higher temperature heat treatment precipitates a complex structure (Fig. 2c) consisting of BaB2O4, BaFe2O4 and Fe2O3.

Bentonites usually have their structure interstratified among members of the family of the montomorillonites and other phyllosilicates (lamellar structure).
The structure of the phyllosilicates comprises the following structural units: a leaf of silica tetrahedrons, connected by oxygen located in the edges of the base, and a leaf of alumina octahedrons, connected by lateral faces.

The XRD pattern comparison also confirms that the crystal structure of Ni–P matrix did not change after incorporation of Al2O3 particles.
Heat treatment of Ni–P/Al2O3 composite coatings leads to changes of Ni–P matrix from amorphous structure to crystallite structure.

The formation of chemical bonds between cerium and manganese ions induces rearrangement of the electronic structure of the solid solution and the variations in the transport and magnetic properties.
The crystal structure of the CeXMn1-XS compounds were investigated on polished lateral surfaces of parallelepipeds at room temperature in the initial state and after carrying out of measurements in the temperature range 80K –500 K.
According to X-ray diffraction patterns for compositions no reflections different from the fcc structure are observed.

Etched structures were measured using an optical microscope, scanning electron microscope (SEM), and 3-D profiler after ultrasonic cleaning.

The nonionic pluronic amphiphilic triblock copolymer of P123, consisting of a hydrophobic block of (PO)70 and a hydrophilic block of (EO)20, plays as the structure-directing and protecting agent in the template syntheses of Cu2O nanocubes.
They explained that the weak covalent bonds between Cu2O cubes might cause the connection of two nanocubes at the edges and the extended dangling bonds at the cube's corner might adsorb each other to form [O-Cu-O]3- dumb-bell unit, as they act in the microcosmic structure of cuprite lattice.
Because the P123 is not preferentially adsorbed on the different crystal faces of Cu2O, the P123 templates the growth of small as-nucleated Cu2O particles mirroring the fundamental cubic crystal structure of the cuprite unit cell.

Their paramagnetic behavior is therefore not related only to their small particle size, but is also related to their intrinsic structure: to their crystallinity and especially to the distribution of the constitutive ions between the tetrahedrally coordinated sites and octahedrally coordinated sites of the spinel lattice [10].
It could be expected on the basis of literature reports [11] that the nanoparticles have a metastable structure in terms of the distribution of constitutive cations in the spinel lattice.
Moreover, the HREM imaging (Fig. 3) shows that the nanoparticles prepared below 50 oC were poorly crystalline, whereas the structure of the nanoparticles prepared at the higher temperatures was characterised by relatively high regularity, almost free of extended lattice defects. 20 30 40 50 60 70 95 °C 311 440 511 422 400 220 65 °C 50 °C ; 26 h 50 °C ; 1 h 35 °C 25 °C 2 T h e t a [ ° ] Fig. 1: XRD patterns of the samples prepared at different temperatures and with two different times allowed for the precipitation of the hydroxides at 50 oC.

MgNb2O6 (MN), with the columbite crystal structure, is developed as potential candidates of applications in dielectric resonators because of the microwave dielectric properties (dielectric constant εr = 21.4 and quality factor Q ´ f = 93 800 GHz at 1300 °C [2]).
In order to reduce the sintering temperatures of dielectric materials, many attempts have been made, for example reaction-sintering process [3], low-melting glass additives [4], preparing small particle sizes of the starting materials using the chemistry method such as wet-chemical [5] and precipitation methods [6].
The milled different times powders and the crystal structures of the sintered samples were analyzed by X-ray diffraction (XRD; Rigaku D/Max 2550, Japan) with Cu Ka radiation.
The microwave dielectric properties are mainly caused by the porosity, structure defect and grain boundary.
