Hexagonal structure of NaYF4 has three cation sites, one for rare earth ions, one for both rare earth and sodium ions, and the third for sodium ions [5].
Crystal structures of the powders were identified by X-ray diffraction (XRD).

Mostly, the finite element method was used in theoretical modeling of these structures.
The finite element method might be applied to interpretation of structure - properties relationships of composites and nanocrystalline materials.

In this study, we examine how the incorporation of tin into the structure of soda-lime-silica (SLS) glass alters the thermal and elastic properties of the glass, which in turn will govern the magnitude and distribution of the residual stress in the tin penetration zone of float glass.
The substitution of SnO2 for Na2O would result in a more strongly bonded structure.

Synthesis and Characterization of Biodegradable Segmented Liquid Crystalline Poly(ester-urethane)s Jie Du1,a, Xianying Cao1,b 1College of Materials and Chemistry Engineering, Hainan University, Haikou, China, 570228 aj.du.phd@gmail.com, bcxying_02@163.com Keywords: biodegradable; polyurethanes; liquid-crystalline polymers (LCP); thermal properties Abstract.
As the main-chain structure of the copolyesters became more random and harder to crystallize, Tm of the copolyesters decreased.
This was thought to be due to the introduction of noncrystallizable components MD, resulting in the lowered crystallization rate and the random structure of the copolymers.

It indicated that the PZN-PZT ceramics formed a single-phase solid solution with pervoskite structure, and no other phases were detected.
It can be seen that the composites showed compact structure and the ceramic powders could combine with the polymer matrix homogeneously.

The similarity of IR spectra indicates the similarity of the backbone structure of all polymers.
The unique peaks of νC=N from VP and δC-OH from VLB indicates that only the “templet” ions were leached, while other structure of the polymer was not destroyed.
