Traditional treatment with a NaOH solution only maintains partial fibrous structure.
After being immerged in PBS (pH = 7.4) or distilled water for 12 weeks, the post-treated chitosan nanofibers can preserve the original structure.
The post-treated SF/CS nanofibers could maintain the nanofibrous structure in culture medium for 54 days and were suitable for human fetal osteoblastic cells proliferating and differentiating.
The cross-linked mats could maintain their morphology and porous structure upon immersion in water for relatively long period.

Results and Discussion 3.1 Phase structure analysis The phase purity and structure of semiconductor materials can be characterized by XRD.
The MgO exhibits a cubic structure with the standard JCPDS card no. 77-2179 and cell parameter of a = 0.4211 nm and space group: Fm-3m (225).
The ZnO/MgO adsorbents have a mesoporous structure (Figure 10(f)), indicating that the pore filling plays a role in the adsorption of CR dyes.

It is generally accepted that in this type of anodization a high current density is the main driving force for arrangement of pores into a close packed hexagonal structure [7, 8].
Moreover, the upper part of the AAO is detached revealing an inhomogeneous AAO structure beneath.
Although both samples are built of an integrated AAO structure, there is a distinct difference in morphology of their skeletons.
After the breakdown, a new process has begin which resulted in a formation of the disintegrated AAO structure.
Chemical composition and the surface structure were also analyzed.

Optical microscopy showed martensitic structures with very fine grains in all the tested samples.
This structure is unstable.
From literature [12], the 15-5 PH stainless steel has a martensitic structure.
In Figure 19, the samples were at their peak strength and lath martensitic structure was present.
The structure of both vendors seems to be similar except the fact that vendor G has more rounded structures which is in accord with the lower strength.

In SLS, a laser sinters powder particles selectively layer by layer, building up solid structures without support structures.
These structures are built using stimuli-responsive materials with the geometrical freedom of 3D printing to create structures that dynamically change shape in a predetermined manner.
Shape Change Mechanism for 4D-printed Structure generally undergoes three-stage processes: 1.
Shape memory photopolymers have already been developed, mostly based on acrylate or methacrylate chemistry with accurately designed network structures.
