With the assistance of anion surfactant sodium dodecyl sulphonate (SDS), spindle-shaped nanostructured lithium iron phosphate (S-LFP) was synthesized in glycol-water media via a novel refluxing method under N2 atmosphere. FeSO4, (NH4)2HPO4 and LiOH were used as Fe, P and Li sources, respectively. The crystal phases were analyzed by X-ray diffraction (XRD). The morphology and spindle-shaped nanostructure were observed by field emission scanning electron microscopy (FE-SEM). The results showed that the purity of the product was greatly influenced by the volume ratio of glycol to water. With the increase of the ratio, the crystal phases tended to pure LFP. On the other hand, with the increase of SDS amount, the particles tended to uniform and spindle-shaped morphology.

The hydrolysis effect of ionic liquid glycine chloride [Gly]Cl aqueous system without any catalyst on the degradation for chitosan were studied. The molecular weight (Mw) and degree of deacetylation (DD) of degraded products were tested via the viscometric method and the titration method, respectively. The structure of the raw and degraded chitosans were assessed through Fourier transform infrared spectroscopy (FTIR) and X-ray powder diffraction (XRD). Besides, the antibacterial effects of different Mw chitosans to Escherichia coli and Staphylococcus aureus were evaluated. The results showed that [Gly]Cl aqueous solution was of good assistant degradation effect for chitosan and different molecular weight (300-800 kDa) chitosans were obtained with different processing time via the ionic liquid hydrolysis method. The DD of degraded chitosans tested from titration method was almost unchanged by the treatment. The FTIR and XRD results showed that the ionic liquid degradation had no obvious effect on the molecular structure of chitosan. Besides, the antibacterial activity was closely relevant to the chitosan concentration and Mw. When the concentration was greater than 0.005% (w/v), chitosan began to show strong antibacterial activity. Molecular weight of 636 kDa exhibited commendable antimicrobial properties to E. coli and S. aureus simultaneously.

A green oxidation of benzylic alcohols to the corresponding aldehydes or ketones was achieved in aqueous media using ionic liquid/H2O2/HCl catalytic oxidation system. The procedure is mild, environment-friendly and simple. Ionic liquids can be successfully recovered and reused for the oxidation of the same (different) substance. The directing effect of the ionic liquid is supported by the good selectivities and yields. These reactions demonstrate the catalytic oxidation and phase transfer function of the ionic liquid is stronger than that without ionic liquid.

Surfactant-templated synthesis of ordered nanostructured materials attracts more and more attention. In this paper, ordered nanostructured Fe3O4powder was synthesized via a facile reflux method in ethanol-water media using sodium dodecyl sulphonate (SDS, C12H25SO3Na) as template. XRD and VSM were used to characterize the ordered nanostructure, inorganic phase and magnetic properties. Results show that Fe3O4powder is of an ordered nanostructure of 7.6 nm which was detected by SAXRD and the inorganic phase is composed of cubic Fe3O4nanocrystals. VSM analysis shows that the ordered nanostructured Fe3O4exhibits a two-phase structure and a soft magnetic property with a saturation magnetization of 40emu/g.

In this paper, C/SiO2 composites were fabricated by self-assembly process combined with heat treatment. The X-ray diffraction (XRD) analysis, SEM and impedance analyzer were used to investigate the microstructure and radio-frequency dielectric properties of the composites. The results showed that the matrix of C/SiO2 composite with a periodical structure formed by the hexagonal stacking of SiO2 microspheres. The sheet carbon distributes in pores formed by SiO2 microspheres and act as the functional phase in the composite. The results indicate that the permittivity of C/SiO2 composite could be easily adjusted by controlling the content of Carbon in the composite. Both real and imaginary parts of the permittivity increase with the content of carbon, but decrease with the frequency.
