Intermatallics compound Ni3Fe has L12 crystal structure.
The Ni3Fe alloy has a disordered structure above the critical temperature Tc and an ordered structure below Tc.
It was suggested that alloy stoichiometry strongly influences grain-boundary chemistry which in turn, affects the grain-boundary cohesion [10].
Therefore, we can deduct that the structure defect—vacancy is formed in rich Fe alloy and anti-site defect is formed in rich Ni alloy.

Results and Discussion The XRD analysis was used in order to investigate the phase structure of TiO2 and Fe-TiO2 nanoparticles.
This suggests that some pertubation takes place in the anatase structure after the introduction of Fe (III) ions [11].

Most probe designs for small molecule molecular imaging typically begin with drugs that modify known structures.
This usually requires structure-activity relationships (SAR) to determine the optimal probe position.
MS analysis showed that residues Arg251 and Trp249 were labeled by probes, and from the crystal structure of MFE2.

Researches showed that the nature of a surface of composition depends on structure and on length of oligoester.
Particle size of the modifier depends on structure of composites and makes from 0.3-3 microns.

Using X-ray phase and X-ray structure microanalysis, it was established that the initial single crystal wolfram consists of Fe0.5Mn0.5WO4 and Fe0.3Mn0.7WO4.
Conducting the model experiments on sintering with the subsequent removal of water-soluble compounds (alkalization) made it possible to follow the change in the structure of wolframite.
A large amount of information on the process of tungsten-containing raw materials sintering with alkali metal carbonates is presented in the literature [5–9], but data on the kinetics and chemistry of the interaction in FexMn1–xWO4–Na(K)2CO3 mixtures during heating is very limited.
According to the results of thermal analysis, during the heating (20 °C/min) of initial wolframite to 1000 °C in the air flow, no transformations in the mineral structure were detected.

Different kinds of silicon structures were found in the coatings.
As known, there exist many different structures of silicon, like cubic, tetragonal and hexagonal.
In the deposition experiments, different structures of silicon appeared by different deposition methods and conditions.
Following the experiments, two different structures [11-12] were selected for the coating original models.

Pore structure HA microspheres with diameter of 2μm and uniform distribution can be obtained when the concentration of Rutin was 0.01wt%.
HA microspheres self-assemble by short rod, and the pore structure are formed by rods.
The structure of Rutin has plane double benzene ring similar to 17-β-E2 and DES.
HA nuclei priority growth along the c-surface into rod-like structure.
As a result, nucleation from the surface of the spherical micelle, and finally generate pore structure HA microspheres.

The interconnected structure of cellulose microfibril having a diameter of 27 nm was observed by TEM.
The properties of NR can be tailored by the addition of fillers of varying surface chemistry and aggregate size/aspect ratio to suit the application concerned.
In this work, as-prepared CMF, which is mainly nanosized fibrils with web-like structures, was used for preparing NR nanocomposite films.
The increasing in toughness of the composite film is the effect of long fibril characteristic and interconnected web-like structure of the CMF.
The CMF, prepared by acid hydrolysis of cellulose from banana peel, consisted of interconnected web-like structure with an average diameter around 27 nm.

Various studies have shown that most X7R dielectric materials exhibit core-shell structures in the grains.
In addition to these additives, rare earth oxides doping into BaTiO3 ceramics could greatly change the microstructure, phase composition, density and properties of mechanics, physics, chemistry and sintering[11-16].
For chemical characteristics, there are the core-shell structure caused by non-uniform doping and homogeneous structure caused by uniform doping.
In the BT- Nb2O5-ZnO system, that Nb5+ diffuses difficultly in BT grains results in the appearance of the core-shell structure[25].
The type III REO(Nd, Ce and Pr) doping could destroy the original core-shell structure and form a new core-shell structure[29, 30], in which the shell region was decreased and the core region was increased, so the dielectric constant peak at 40ºC were depressed, the peak at 127ºC were raised.

In this collection of papers, we present the last advances in the field of sustainable materials and structures as they appear in the proceedings of the 2021 edition of the international workshop ”Engineering Materials for Sustainable Structures” (EM4SS’21) organised by the University of Modena and Reggio Emilia under the auspices of the Italian Industry Association for composite materials (Assocompositi).
The symposium gathered researchers alongside industrial partners active in the field of sustainable technologies and mechanics of complex materials and structures.
Again, long-term performance of novel construction materials plays a crucial role in determining resilience and reliability of modern structures.
Mechanics of Solids and Structures The Session reports on state-of-the-art and new concepts in the mechanics of solids and structures, includingmultiscaleandasymptoticmodels,homogenizationandinstability,nonlinearelasticity,wave propagation and reflection, plasticity, fracture mechanics.
