The resulting structure of contacting crystallites.
The energies are given relative to their minima for the bcc structure.
So, considering the atomic structure near the interface as an alloy, it can be assumed that under certain conditions the copper atoms arranges in the bcc structure.
The structure of this layer differs from the structure of the corresponding bulk materials.

The scaffolds obtained by this process have a lamellar architecture that exhibits similarities with the meso- and micro- structure of the inorganic component of nacre.
Up until now, there was no single method available that could replicate the interfacial chemistry, the architecture and the interfacial roughness of the shells.
A finer microstructure is obtained for high interface velocity, without affecting the long-range order of the entire structure.
In addition, our results indicate that by controlling the freezing kinetics and the patterns of the cold finger, it is also possible to build mesostructural features and gradients (Fig. 1g), similar to the osteonal structure of compact bone, that could contribute optimizing the mechanical response of the final materials, for example by stiffening the structure and limiting torsion.
Optimization of the porous structure of calcium phosphate implants for bone substitutes and in situ release of active principles.

Characterization of the prepared ceramics with XRD and FESEM showed that lattice parameter and grain size are slightly increased, indicating Cu-excess to have the big impact on the both phase structure and microstructure.
The phase structure and microstructure of these new materials also studied in order to explain the mechanism of dielectric properties.
Based on the increase of dielectric constant, it is suggested that the occupation of Cu-site (Cu+ and/or Cu2+) by Ti4+ (classified as a donor dopant), maybe attribute to the reducing oxygen vacancies in CCTO structure and lower the conductivity of CCTO.

The structure and size of the MNP@P(MAHCD-co-MMA) nanoparticles were confirmed by FTIR, TGA, XRD and TEM.
CDs form the structure of toroidal, hollow truncated cones with hydrophilic outside and hydrophobic internal cavities.
Nowadays, magnetic nanoparticles with tailored surface chemistry have been widely used in various fields.
The size, structure and surface properties of the MNP@P(MAHCD-co-MMA) nanoparticles were characterized using different analytical tools.
This revealed that the resultant nanoparticles were pure Fe3O4 with a spinel structure.

It is seen from Fig. 2 that both two XRD patterns exhibit a sharp peak at around 2Theta=20.5o, which is a characteristic peak of PVDF β-phase crystalline structure, corresponding to the β(200/110).
F4 membranes have high porosities and interconnected porous structures, so they are able to uptake large amounts of liquid electrolytes and offer effective conduction channels, which in turn lead to high ionic conductivities and increase charge and discharge capacities.
The good cycle performance of F4 fibrous membranes could be attributed to their unique porous structure, high liquid electrolyte uptake and high ionic conductivity.

Increasing the concentration of PS in DMF reduces the contact angle to 150° and increases the contact angle hysteresis to 60°, which was shown to have a bead-free fiber structure.
The nano-sized fibers in this structure are too thin to support the entire membrane [13] and observations of these thin fibers show the membrane breaking very easily.
Fibers with micro-sized diameters provide support for the entire membrane while the nano-sized membrane and bead structures create the appropriate roughness.
To obtain more durable superhydrophobic fibers, we developed a multilayer structure of bead-on-string fibers using a 5% PS solution and micro-sized fibers using a 20% PS solution deposited simultaneously.

Although this method can detect the actual effect of the magnet design, it is time-consuming and difficult to get a satisfactory magnetic structure.
In addition, the magnet structure forms have many types, such as the C-type, H-type, double-column type, U-shaped, etc.
The structure is similar to a box with a height of 200 mm.
