“…In the second stage, a distinct weight loss occurred in the TGA analyses between 250 and 450 • C for the combustion of organic groups in the cross-linked gels. 23 The sample prepared using more water content (R w = 50) has the least weight loss, at 14%. The sample obtained without any water added (R w = 0) exhibited the highest weight loss, about 27%.…”

“…The detection limits of the four analytes were 5.0, 6.7, 4.5 and 6.0 mg/L, respectively. These four analytes can be well separated in 10 min [246]. A method based on CE for determination of bufadienolides in toad venom and their Chinese medicinal preparations was also developed.…”

Traditional Chinese medicines (TCMs) are getting more and more popular nowadays in the whole world for improving health condition of human beings as well as preventing and healing diseases. TCM is a multi-component system with components mostly unknown, and only a few compounds are responsible for the pharmaceutical and/or toxic effects. The large numbers of other components in the TCM make the screening and analysis of the bioactive components extremely difficult. So, separation and analysis of the desired chemical components in TCM are very important subjects for modernization research of TCM. Thus, many novel separation techniques with significant advantages over conventional methods were introduced and applied to separation and analysis of the chemical constituents in TCM. This review presents just a brief outline of the applications of different separation methods for the isolation and analysis of TCM constituents.

“…Acetylacetone is employed as one of the chelating agents with metal alkoxides because it significantly changes the hydrolysis behavior, thus giving rise to a new molecular precursor. [12][13][14][15][16][17][18] In the present study, we report on the electrical and optical properties and the microstructures of Mg(Zr 0.05 Ti 0.95 )O 3 thin films prepared by the sol-gel method using acetylacetone modifier on n-type Si(100) substrates followed by annealing at different temperatures.…”

In this study, electrical and optical properties and the microstructures of Mg(Zr0.05Ti0.95)O3 thin films prepared by the sol–gel method using acetylacetone modifier on n-type Si(100) substrates followed by annealing at different temperatures were investigated. The increase in grain size of Mg(Zr0.05Ti0.95)O3 thin films occurred with an increase in annealing temperature and the ratio of acetylacetone to (Zr+Ti) component. Furthermore, it was determined that with an increase in the annealing temperature from 600 to 800 °C and the ratio of acetylacetone to (Zr+Ti) component from to , the dielectric constant increases from 9 to 14.8 at 1 kHz and the loss tangent decreases from 0.3 to 0.04. In addition, the optical bandgap and the leakage current density also improved with increasing annealing temperature and the ratio of acetylacetone to (Zr+Ti) component. These results indicated that the sol–gel route using acetylacetone as a modifier can generate Mg(Zr0.05Ti0.95)O3 thin films of high quality with the optimization of the content of acetylacetone and the annealing temperature.
