Foam drainage half-life length is determined by the molecular structure of foaming agent system.Longer half-life shows better initial stability before the bubble entering the formation.However, the differences in molecular structure of foaming agent will lead to different of bubble in shear resistance, temperature resistance, salt resistance and other aspects, whether the half-life should be as long as possible, this issue needs to be verified.

X-ray diffraction (XRD), thermal gravimetric analysis (TGA), and temperature programmed reduction (TPR) were used to characterize the average structures and redox properties of these materials.
The structure (a) and main chemical reactions (b) in an automotive three-way catalytic converter.
Atomic-resolution phase-contrast imaging was used to determine the degree of crystallinity and disorder and surface structure in individual nanoparticles.
It is clear that the XRD pattern of Ce precipitates can be indexed on a face-centered cubic, fluorite-type unit cell, but the synthesized of Pr/Tb precipitates are hydroxides (Pr(OH)3 and Tb(OH)3) with a hexagonal structure.

Furthermore, with the special structure of the material, it meets the needs of drug absorption and delivery.
Moreover, CTO:Er films show excellent biocompatibility [11-12], and therefore the typical structure of the films may be exploited as a drug release platform.
By utilizing fibrous structures, we have enhanced drug loading capacity and achieved sustained release of curcumin over a 5-hour period.
Results and Discussion Structure, and morphology of CaTiO3:Er3+ flim Fig. 1 shows the XRD patterns of the as-synthesized samples with Er3+ doping content.
These results indicated the successful synthesis of the crystalline structure of CaTiO3 films.

Abstract.
Phase structure of the coatings were studied using X-ray diffraction (XRD) (JDX-8P, JEOL, Japan, with CuKα radiation (λ= 1.5418 Å) as the X-ray source) technique.
The identification of phase structures corresponding to different c.d.’s were obtained, and is shown in Fig. 1(B).
From the intensity and the diffraction angle of XRD signals, it may be observed that c.d. plays an important role on both composition and phase structure of the coatings.
The lattice growth from cubic to face centered structure was observed, indicating the enhanced crystallinity and micro hardness of the Ni-W coating, as evident from the data.

Abstract.Using orange peels as raw material, a stacking structured carbon material has been synthesized through carbonizing and activating process.
Herein, we report a novel stacking structured orange peel carbon (OPC) material synthesized through carbonizing and activating process.
The synergetic effect of stacking structure, thin sheets and irregular wrinkled surface of OPC on the electrochemical performance of the OPC/S cathode is investigated in detail.
The stacking structure is well remained in OPC/S composite, which may help to enhance the electrochemical performance of the OPC/S composite.
Conclusions A novel stacking structured orange peel carbon (OPC) material has been synthesized through carbonizing and activating by KOH.
