The amorphous carbon structure was obtained at the diffraction angle of 23o.
It shows that the carbon structure is fiber-like with a tubular shape.
It shows that the structure of the activated carbon is an irregular shape.
Moreover, activated carbon has a rich pore structure.

Pure molecule of NPG, PE or TRIS has layer-shaped structure.
Structure difference between NPG and PE is the biggest, so the hydrogen bond is affected more serious.
Structure difference between TRIS and PE is the smallest, so there shows a different case.
This is because PE and TRIS are close in crystal structure, atom mass and atom size.
Because hydrogen bonds are influenced by the structure defects, there is no uniform trend between the value of x and specific capacity.

This can be explained by the different structures of the calcination precursors.
We can obtain different precursor structures with different n()/n(Y3+).
Three-layer core-shell structure had shortened the diffusion distance of Y3+ and Al3+.

The technology can form a predefined three-dimensional structure with certain shape and size, suitable for variety of natural polymer materials (the most similar with extracellular matrix, such as fibrin, sodium alginate, chitosan, hyaluronic acid) with gelatin coupling forming; therefore, it satisfied majority cells needs of choosing the gelatin-based composite hydrogels reasonably.
Tissue analog precursor should mimic the natural organizations farthest in the structure and function [3], therefore, it should have suitable shape and gradient distribution in macro structure, should have vascular-like systems for transmission the nutrients and metabolic residue in micro structure, materials also need to have diversity available for cell selection.
Based on the technology, more complex 3D structures can be manufactured, both the macro structure forming and micro pore constructing can be coupled to the same forming process, the structure shape and pore is more controllable, the process is relatively easy to information [11-12].
The biomaterials applied to cell assembly should have the bionic features in composition and structure, were chosen according to two aspects: (i) should be compatible with cells, suitable for cell survival, growth, and proliferation (i.e., water diffusible, biodegradable, and biocompatible) and (ii) should be easily processed and shaped without causing harm to the cells.

.% of silver in the structure and the diameter of the silver particles on the silica carriers was 30 ± 7 nm on average.
Depending on the annealing temperature after the air-drying, the structure of both silver and silica vary.
The crystal structure of the powder was examined by q-2q XRD measurements (Philips PW1710) using CuKa radiation.
Processing provides a porous silica structure that holds together, and has quite similar silver structure as the powder applied.

Long chain sulfur compound break down into small molecules, damaging the colloidal structure of heavy oil, improving the quality of heavy irreversible.
By the means of pyrolysis, the colloidal structure in resins was damage to disintegrate between saturates and aromatics. 2.2 Sub-critical water modification Sub-critical water is a new medium and a good solvent being developed under the idea of green chemistry.
(2) The fA in SWM, CM and CMH decreased, indicating the degree of Aromatic structure lower in modification process, such as heavy oil colloidal system was destroyed, and aggregates dispersed into small degree and aromatic structure.

It tends to form a very thin and loose structure attached to the beaker wall.
What's more, the high porosity can also mean the confusion of the structure of the backbone of our system, and the confusion of the structure will increase the heat resistance of our system.
SEM pictures show similar structures too.
They also show similar spherulitic crystal structures (see Fig. 3 (a), (b), (c), (d)).

The pretreatments techniques herein assessed were the metal sheet annealing to change the surface chemistry, and the metal sheet mechanical abrasion by sandblasting with the aim to increase the surface roughness.
The microstructural and mechanical results were then correlated to the metal sheet surface morphology and chemistry induced by the different treatments examined through optical profilometry and X-ray Photoelectron Spectroscopy (XPS).
A steel structure supported a screw, which, employing a pre-compressed spring with a load cell, allowed applying a normal force (FN) on the samples through a steel punch.
The Authors also assume that the Sdr parameter cannot describe the porous structure of the oxide layer since this parameter cannot be used to accurately evaluate reentrant surfaces [16].
