Results and Discussion Analysis of the Surface Structure on The Modified Activated Carbon The surface structures of the activated carbons have burnt out pores with tunnel or honeycomb-like structures as shown in Fig. 1.
But also consider the existence of surface chemistry effects.
In addition, it also increases the NiO metal content which affects chemical adsorption and surface chemistry.
This shows that the effect of physical adsorption is still more dominant for CO gas adsorption than the effects of surface chemistry.
Characteristics of compounds that affect surface chemistry are polarity, hydrophobic properties and acid-base bonds.

The micron-scale silver powder was purchased from Aldrich Chemistry having the purity of 99% and size less than 250 nm.
Excess Gibbs free energy drives the agglomerate to become more compact (close packed structure), which results in an increase in the number of bonds.

When the dosage of AMPS is 20%, the apparent viscosity become biggest, the reason is that AMPS is a kind of monomers with anionic group, ionization structure is introduced with AMPS, the chain will stretch because of the electrostatic repulsion of the ionization structure, the product become more viscosity.
The structure of the polymer characterization (IR) The structure of synthetic product was characterized by infrared spectrum.

The result showed that zinc ions were substituted in the structure.
It is intriguing objective to substituted zinc ions into HA structure.
Some studies have been done to study the effect of zinc on HA structure.
This has cause a disturbance in crystal structure of the apatite.

Preparation and analysis of doped TiO2 in the Bi2O3-SiO2-ZnO-B2O3 low-melting sealing glasses Qibin Gua, and Jiamiao Nib Department of Architecture and Material Engineering, Hubei University of Education, Wuhan 430205, China agqibin@hubce.edu.cn, bnijiamiaolf@163.com Keywords: Bi2O3-SiO2-ZnO-B2O3 glass; TiO2; Chemical durability; Transformation temperature Abstract: In this paper, optical, the chemistry stability, and glass transformation, softening temperature were studied on Bi2O3-SiO2-ZnO-B2O3 system glass doped with 2wt.%, 4wt.%, 6wt.% and 8wt.
This is because the PbO glass systems form PbO4 structures easily since Pb plays the role of an intermediate due to its own ionic field strength.
After TiO2 adding into the silicate glass, Ti4+ ions can enter into glass network structure, and [TiO4] and [SiO2] can form a stable glass.
When other components are unchanged in cases, in Bi2O3-SiO2-ZnO-B2O3 system glass, replaced ZnO by TiO2, with the increasing of TiO2 content, one part of TiO2 in the form of [TiO4] entered into the glass network structure, reducing the glass dissociative oxygen, increasing the density of the glass network structure, which leads to increased of the characteristic temperature of glass[1-4].
Conclusions The optical, chemistry stability, glass transformation and softening temperature were studied on Bi2O3-SiO2-ZnO-B2O3 system glass doped with 2wt.%, 4wt.%, 6wt.% and 8wt.
