X-ray diffraction patterns confirmed the FCC spinel structure of synthesized particles.
Introduction The study of nanocrystalline materials is an active area of research in physics, chemistry, medical science and materials engineering as well as in multidisciplinary fields [1,2].
Characterization: The structure and particle sizes were determined by X-ray diffraction (XRD) data.
The decrease in lattice constant for X=1 may be due to total shift of crystal structure from CoFe2O4 to MnFe2O4.
The variation of resistivity can be explained on the basis of actual location of cations in the spinel structure.

Hydrogels are cross-linked polymeric structures, which consist of up to approximately 90% water, the remainder is polymer chain.
Nevertheless, to maintain their structure and softness, hydrogels must be stored in suitable conditions to prevent water vaporization.
The structure of alginates consists of a homopolymeric block of (1,4)-linked β-D-mannuronate (M) and α-L-guluronate (G) acids.
The shrinkage rate was 39% and 25%, respectively for single- and five-layer structures [22].
This structure may provide better conditions for the viability of cells deposited in the hydrogel scaffold [22].

The structures and properties of PLA oligomers were characterized by FT-IR, GPC, DSC, etc.
PLA oligomers' molecular group and structure changes after thermal hydrolytic reactions were determined by FT-IR spectrum(Shimadzu FT-IR, solution-cast film, on NaCl plate), of which typical samples of PLA-W1h, PLA-W2h, PLA-W3h, PLA-W6h, PLA-W9h and PLA-W12h were chosen as typical samples, whose structures and performance were characterized and analyzed.
According to polymer physical sciences, polymer molecular weight and molecular weight distribution are the internal factors which impact the molecular structure and properties of the material.

The efforts of new automotive industry are mainly directed towards the substitution of aluminum for steel in the body structure because the aluminum structures are lighter than traditional steel ones and meet the requirements, in terms of both vehicle design and manufacture.
However, this substitution is not so automatic, but it is important to study the material properties and the structure design, focusing the attention on the methods of joining.
However, this substitution is not so automatic, but it is important to study the material properties and the structure design in order to optimise the car performances.
This treatment is performed to alter the surface chemistry of the adherents.
Single lap joint A wide variety of joint configurations is possible when bonding structures.

From the point of view of material science, the durability of concrete is mainly affected by its components, inner structure and performance.
Considered from the view of material science, durability of concrete is mainly affected by its composition, inner structure and property.
Structure Forming and Characteristics of Common Concrete The structure of concrete can represent the ratio of gas-phase, liquid-phase and solid-phase as well as their mutual relations.
