Results and discussion As shown in the Fig. 2, the film A produced by the MAIP method has poor surface quality, and its loose structure is believed to result in lower hardness.
As shown in Fig. 5, both samples have a dense structure and clear interface although film B contains three coating layers and film A has two layers.
Summary Present study shows the impact of the preparation approach, deposition sequence and mid-layer on the Me/MeN/Me (Me=Al, Ti) multilayer thin film structure and their thermal stability.

Choosing the basis of 6-311++G (d. p) with chitosan as its model, we use the density functional B3LYP method to optimize the structure and calculate the energy for the chitosan and sulfate.
In recent years, the structural and adsorption properties of chitosan and its derivatives by quantum chemistry in theory have been reported.
The structure of chitosan membrane by Ab initio quantum chemical calculation is reported by Zhang Aili[8].
The result of model optimization by Density Functional Theory B3LYP/6-311G (3df, 3pd) demonstrates that the structure of the metal complexes resemble closely the structure of the active sites of metalloenzymes.
Choosing chitosan as adsorbent, the theoretical for the interaction of chitosan and sulfate by quantum chemistry is explored in this paper.

Abstract.
The orientation structure developed by sintering, and the orientation factor achieved 0.85 as determined using the Lotgering method.
This suggests that the ceramic has an anisotropic structure.
Orientation structure has developed with sintering temperature.
Orientation structure was developed with sintering.

Introduction of Ag as a dopant into the lattice structure of TiO2 crystals enhance the formation of reactive oxygen species (ROS), slows down the charge recombination rate, decreases the band gap of TiO2 [11], and finally, efficiently enhances the visible light photocatalytic degradation [12–14].
Si/TiO2 particles are undoubtedly present on the surface of the TiO2+TPMP+APTES+rGO composite, while the presence of rGO can only be suspected since the C and O elements originating from rGO cannot be identified separately due to their presence in the cellulose structure.

The glass chemistry, particularly the content of
modifyer,usually Y or a rare earth (RE) ion, and the volume fractions of these oxynitride glass
phases within the ceramic control the properties of silicon nitride, in particular, creep at high
temperature.
The high temperature mechanical properties, especially creep, of silicon nitride depend on the types and amounts of sintering additives used which determine the volume and chemistry of the grain boundary glasses [2-4, 6-7].
This is known to be due to the increased cross-linking within the glass structure as 2-coordinated bridging oxygen atoms are replaced by 3-coordinated nitrogen atoms [5, 10-11].
Smaller RE ions prefer an oxygen environment in the glass structure so, as N is concentrated in the IG films, smaller RE ions (Lu, Er) diffuse out to the triple points [16].

Sodium ion is expected to be able to stabilize the HA structure since doping with singly charged ions is believed as possible route to stabilize the CHA structure, by substituting for calcium ions and providing the charge balance [5].
The addition of Na+ has been found to have stabilize effect in the structure of HA or b-TCP.
TEM images (a) Na-free HA powders, (b) 10%Na-HA powders which part of the PO4 groups in apatitic structure was replaced by CO32- groups.

Many researchers focus on rectorite as adsorbent and catalyst support for it’s expandable smectite-layer in the inner structure.
The variations in the lamellar structures of Na-R and Co@R were scanned with the small angle XRD.
The crystalline structures of materials showed in the small angle XRD pattern (Fig. 2) are consistent with the standard patterns of rectorite (JCPDS File No. 25-0781).
