Introduction Corrosion of engineering structures and components in service has continued to be a huge source of concern to corrosion experts in the academia and industries.
The surface of metallic structure is attacked through the migration of ions away from the surface, resulting in material loss over time.
The adsorption process is affected by the chemical structures, allocation of charge in molecule, the nature and apparent charge of metal, and the type of aggressive media [25].

Combustion of polymeric materials is a complex process involving combinations of heat and mass transfer/diffusion, fluid dynamics and degradation chemistry.
The release of NH3 induces the formation of a foam structure in the polymer mixture.
Sample 4 presented the smallest expansion factor with a relatively dense structure (Figure 3 (e)).
Its structure after fire test (Figure 3 (f)) was similar to sample 1.

We reported on the synthesis and characterization of novel polymeric precursors for SiCBN and BCN ceramics via hydroboration of organosilazane and triethynylborazine with borazine, including the pyrolytic chemistry.[5-7] The liquid type of polymers were advantageous with higher processibility and stability in air than the previously reported products.
Results and discussion Fig. 1 shows representative SEM photographs of various porous SiCBN and BCN ceramics with flat plane or deep-seated structures.
It is obvious that the achieved porous SiCBN and BCN ceramic contain 3 dimensionally ordered structures with excellent regularity at least in short range.
In addition, the highly ordered porous ceramic structure was reproducibly obtained as the slower heating rates gently released the gaseous products during pyroysis.
In particular, below 600� it should be gently annealed to consolidate the infiltrated polymeric structure because major thermal decomposition with high mass loss was occurred at the range.

The crystal structure of WO3 nanostructure was triclinic phase and their morphology was mainly one dimensional nanorods.
In modern synthesis and preparative chemistry, more and more hydrothermal methods are used to carry out the reactions which cannot happen under usual conditions, and various new compounds and new phases are synthesized.

Pereparation of hollow silica core/mesoporous silica shell monodisperse uniform spheres Lili Lv1,2, Wenhao Geng2, Cheng Wang1,a*, Zhuoying Xie3,Yuanjin Zhao3, Yuan Guan2, Xuduo Bai1, Liguo Sun2,3b* 1 Key Laboratory of Functional Inorganic Material Chemistry, Ministry of Education of the People’s Republic of China, Heilongjiang University, Harbin, 150080, P.R.
The hollow core and mesoporous structure were formed by calcination which acts as the removable templates.
In this paper, we reported a method to synthesize monodisperse hollow mesoporous silica of well-defined core/shell structure.
By comparing the PS/silica/CTAB composite spheres calcined before (Fig.1c) and after (Fig.1d), no obvious shrinkage was observed, indicating the structure of the spheres are stable.
The well-defined step between 0.4 and 0.6 of P/P0 indicates a highly narrow mesoporous structure.

Beginning from the manufacture process of metal rubber material, the structure and electromagnetic shielding mechanic were studied.
Using the microscope we can see that its internal frame is connected disorderly by a considerable volume of metal silk, and it is just like the net structure of rubber’s microscopic view.
It is because that the structure of metal rubber material is irregular and special.
Shielding Efficiency fitting curve Summary Researching from the manufacture process of metal rubber material, the structure and electromagnetic shielding mechanics were analyzed, and the mathematic model of electromagnetic shielding efficiency was deduced.

However, ageing of coating was dependent on its structure.
These may include the enhancement of mechanical properties, visual appearance or corrosion resistance or may provide special magnetic of optical properties[1-3].The degree of environmental degradation that occurs in a fiber reinforced polymer composite structure is linked directly with the amount of moisture that is absorbed.
Experiments Materials The epoxy resin (E-51) used in this study was supplied by Nantong Xingchen Synthesized Resin Institution, which structure was shown as following: The E-type glass fibers investigated in current studies were commercial.
Moisture can potentially cause debonding at the fiber/matrix interface not only through chemical attack and reaction, but also through mechanochemical effects such as osmotic pressure [8].The mechanism of attack at the interface is decisively governed by the chemistry, structure, morphology, and modes of failure at that interface[9].

Different pretreatment methods have led to various surface structures, which resulted in various effects on removal heavy metals.
Introduction Sepiolite is a Mg-silicate with fibrous morphology, whose structure consists of talc-like ribbons parallel to the fiber axis.
This special structure brings about a high adsorption capacity.
Effect of Modification Degree on the Structure of Sepiolite When sepiolite was modified by 15% hydrochloric acid, the various RMR was obtained under different modification time.
XRD shows that during the modification, if the RMR is too high, the octahedral part in sepiolite structure transforms into tetrahedron.

The TiAlN coating shows the highest hardness at a certain N2 flow rate when it has the most compact structure.
Increasing R (N2) further, TiAlN coatings turn a single B1-NaCl type cubic structure.
Additionally, the cross-section morphologies of TiAlN coatings turn from a dense fibrous structure to a bulky columnar structure with increasing R (N2)，as shown in the cross-section images (Fig. 3b-d).The TiAlN coatings show different microstructural morphology as R (N2) increased, and we acquired the most compact coatings at R (N2) =10%.
