Microstructural evaluation conducted by X-ray diffraction and scanning electron microscopy confirms the hierarchical structure of the ceramic grain.
Hierarchical-structure Ba0.985Bi0.01TiO3-BaTi1-xZrxO3 (abbreviated BBT-BTZ100x) powders have been synthesized.
Then, BTZ would grow at the surface of BBT because the similarity of their geometrical structure.
This structure depresses the volatilization of Bi2O3 and abnormal grain growth.
The composition inhomogeneity and structure defects facilitate the diffusion phase transition (DPT) and result in a widening peak in the DSC curve.

Results and Discussion 3.1 Mechanical Properties Tensile properties of film materials relate to their chemical structure can be described by tensile strength and elongation.
This is probably because degeneration of whey protein exposed more sulfydryl and hydroxyl bonds to form disulfide bonds and enhanced integration between intermolecular, resulted a better linked structure of the films. 3.5 Water Vapor Permeability Fig. 3 Water vapor permeability of films at four different RH gradients.

While achieving exceptional properties in these areas, the expanding application of composites necessitates the development of more complex, multifunctional resins to enable greater efficiency in composite structures.
Vitrimers are crosslinked polymers, similar to thermosets, that possess side chain chemistry that disassociates above a set temperature.
Especially if the reversable side chain chemistry is present in the initial components (rather than synthesized during manufacture).

It has been revealed that WNS has macroporous structures with a pore size distribution more homogeneous than that of olive pits.
Abrasion strength of the sinter prepared with WNS of different sizes When using pyrolyzed WNS of 1 mm in size, the fuel particles burn quickly and do not allow the required amount of heat to produce a strong sinter structure.

The pore structure and surface properties were characterized by N2 adsorption at 77K, transmission electron microscope (TEM) and Fourier transform infrared spectroscopy ( FTIR).
Results show that the prepared carbon is a microporous- and mesoporous-adsorbent with developed pore structure and abundant surface oxygen-containing groups.
Activated carbon (AC) is widely used to remove organic or inorganic chemicals in liquid or gas phase as adsorbents because of its huge surface area and well-developed pore structure.
The pore structure parameters (Table 1) indicate that KAC pocesses far larger specific surface area and pore volume.
The high adsorption capacity of KAC can be attributed to its larger surface area, developed pore structure and abundant surface oxygen-containing functional groups.

The results suggest the as-obtained samples are spherical structure with the diameter of approximately 10-20 nm, the absorbance intensity in the visible light range increased with the amount of deposited increased.
The remarkable photocatalytic activities are due to the high-quality of composites structure and the driving force for electron transfer in nanoparticle.
The crystal structure of samples was characterized by powder X-ray diffraction (XRD) (D/max-IIIA, Japan) using Cu Ka radiation.
This implies that there is no significant change observed in phase structure and crystallite size of TiO2 during the whole precipitation.
From all of the above investigations, it is evident that relatively Cu(OH)2 can be deposited on the anatase N-TiO2 templates that preserve their nanospherical structure.

The establishment of an effective finite element model for bridge structure is essential in the health monitoring system for Bridge.
So it is necessary to verify and update this FEM using the measured data to acquire the FEM which is more similar to the actual structure [2].
Hence the static method has a good agreement with the practical structures; it can be used as the baseline FEM for damage detection, health monitoring, performance evaluation and design verification of structures.
Response surface method is applied in chemistry, agriculture, aerospace, machinery and other experimental fields for early [7] and gradually applied in civil engineering (structural reliability analysis) field.
Damage detection of structures based on static response.

The modified Bentonite structure showed increased interlayer space due to the introduction of molecules or ions.
The mixture was stirred for an additional 4 hours to facilitate the intercalation of the surfactant into the clay structure.
Upon intercalation with CTAB (Cetyltrimethylammonium bromide), the modified Bentonite structure shows new absorption bands at 3448.53 and 3628.13 cm-1.
The FTIR spectra of the modified Bentonite structure reveal supplementary absorption bands at 3448.53 and 3628.13 cm-1.
These bands suggest an increase in interlayer space in the intercalated structure, caused by the introduction of molecules or ions between the montmorillonite mineral layers.
