Figure 2 Polyethylene structure Most of the PE resins are formed of ethylene / α-olefin copolymerization, and the polymer structures vary by α-olefin type (Table 1) [11].
The most popular way of NCC production is to purify the crystal structure by eluting the amorphous parts of the cellulose structure with the use of strong acids [57].

Introduction The structure of thin film surfaces is determined by both thermodynamics and growth kinetics.
To analyze the interface structures of the metallic multilayers, X-ray diffraction (XRD) technique was carried out.
From the previous study the surface structure is considered to be an Fe(100)- c(2×2)O reconstruction surface [14, 15].

This work deals with the study of the structure of TiO2 nanoparticles that were synthesized by the sol-gel method (using isopropanol as solvent), and calcined at 200 and 500°C.
This sample showed the following proportion of phases: anatase (62.88%) with a tetragonal structure (a=0.3790926, b=0.3790926, c=0.9495732) nm; and b) brookite (37.12%) with an orthorhombic structure (a=0.9167624, b=0.5416461, c=0.5210546) nm.
The synthesis of nanostructured materials such as TiO2 nanoparticles by wet chemistry routes is a powerful way to obtain reproducible homogeneous samples.
Apparently, the type of catalysts added during hydrolysis influences both the phase structures and crystallization of the TiO2 nanoparticles [20].

The structure of geopolymers was studied by using X-Ray diffraction (XRD).
For these compositions the XRD patterns indicated that the structure of the resulting geopolymers were essentially amorphous.
This suggests that the Na-PSS geopolymers consist of disordered frameworks with short-range order, with structures similar to those of felspathic glasses [23,8].

The material is cured by the UV light radiation, which stiffens the structure, reproducing a given 3D morphology.
This step is crucial for the purpose of forming the solid structure in the 3D printing procedure.
In case of the FDM method, the filament is deposited layer-by-layer forming a topologically nontrivial 3D structure.
With such resolution, the possibility of bioprinting models of the physiological structures is quite realistic.

This paper deals with the development of a new sensing structure based on polymeric foils and optic fiber sensors, namely the Fiber Bragg Grating sensors.
The number and sophistication of optoelectronic systems found in smart structures is increasing at an unprecedented level.
The Bragg structures were first printed in the fiber core using a communication wavelength range (1520-1570 nm).
After the thickness homogenization, the layer is cured in the oven, to become a solid structure.

Introduction The compound of nitrogen heterocyclic pyrimidine has been one of the important research areas of chemistry and biochemistry, which is widely concerned by medical and pesticide researchers. 2-chloro-4,6-diamino-5-cyanopyrimidine is an important pyrimidine intermediate, which can be applied to synthesize bactericide, pesticide, herbicide, anxiolytic and anticarcinogen [1,2]. 2-chloro-4,6-diamino-5-cyanopyrimidine is usually prepared with sodium salt of 1-amino-1- cyanamino-2,2-dicyanoethylene.
The structure of the product was confirmed by IR, NMR and MS characterization.
The structure of the target compound was confirmed by IR, NMR and MS characterization.
The structures of three new pyrimidine derivatives were confirmed by IR, NMR and MS characterization.

It uses a specific structure of copolymerization[1].
This is mainly due to spherical molecular structure of functional polymer, and it’s rigid, less flexible molecular chains, so, the migration of it in rock pore is easy to be stuck.
Unique features of molecular structure of functional polymers have a stronger ability to improve oil recovery.

Most of deacidification methods were used on degraded paper damaging the fibers structure and the ink.
The mechanical properties of different paper samples are substantially influenced by the individual characteristics of cellulose fibers, by the nature, concentration and chemical properties of fillers and additives, as well as by the network structure of the paper [7].
The process should be related to the fact that ethanol can form hydrogen bonds with different cellulose chains, thus creating a sort of crosslinked structure, and the alkali reserves infiltrate the aperture of the cellulose fibers.
