Therefore, heat and cold resistance, water and weather resistance are required for structures made of PCM along with the usual requirements for mechanical strength [5, 6].
One of the main manifestations of the impact of environmental factors on PCM is the saturation of their structure with moisture [20-22].
As a result, there is a partial plasticization and restoration of the amorphous structure of the matrix.

The structure, morphology, magnetic, optical and electrical properties of BiFeO3 were characterized by XRD, SEM, VSM and UV-VIS.
According to the JCPDS powder data (Card No. 20-0169), the products have a perovskite structure.

Results and Discussion In this study, FTIR was used to characterize and compare the structure of lignin isolated from bagasse and synthesized lignin-Mg(OH)2.
Based on the FTIR spectra, the functional group of lignin bagasse and lignin-Mg(OH)2 structures can be analyzed.
Bagasse’s lignin shows a wide band at a wavenumber of 3413 cm-1 which is associated with the presence of hydroxyl groups in phenolic and aliphatic structures.
The modification of lignin bagasse with Mg(OH)2 give some changes to the lignin structures.

In general, there are at least four ways to synthesize AgNWs, starting with template-based and seed-based (electrochemical methods, wet chemistry, and polyols) methods.
Template-Based Method The concept of "template-assisted assembly" refers to method of using predetermined shapes or structures.
Typically, template-based method can construct a three-dimensional ordered onlooker materials structure. 
Additionally, the template is frequently made of polymer with particular structure or material with a system structure, such as graphene foam, nickel foam, sponge, polyurethane, etc [12]–[14].

These inserts have the shape of tablets or rods, are the first to evaporate, and form transition layers of the required composition and structure.
Evaporating and condensing simultaneously with the ingot material, they form the composition, structure and properties of the ceramic layer.
The condensing liquid phase actively interacts with the surface of NiCoCrAlY bond coat, changing its chemistry, and forming the second bond coat with high aluminium content, close to NiAl in its composition.
Study of the coating fine structure revealed that the layer based on boron carbide, owing to the developed and used 'know-how" in the technology of evaporation and condensation, is a multiphase nano-structured coating with inclusions of textured nanoparticles of about 10 nm size.
One of the examples of graded coatings with a nano-sized structure is the hard graded Sn-Cr-MgO coating, the distribution of chemical elements and microhardness of which are given in Fig. 8.
