摘要：
Stable and monodispersed silver nanoparticles were produced through a mild, convenient, one-pot method based on the reduction of silver nitrate in the presence of poly(amic acid) (PAA) as a stabilizer. The surface plasma band transition was monitored along with time in the reaction mixture for three sets of experiments by ultraviolet-visible spectroscopy. Analysis of the data with the Avrami equation yielded n exponent with values between 0.5 and 1.5, demonstrating three-dimensional heterogeneous nucleation and diffusion-controlled growth, accompanied by soft impingement effect. XRD and TEM analyses show a softly agglomerated polycrystalline state and a nearly spherical morphology (<50 nm) of nanoparticles. The FT-IR result indicates that the PAA molecular structure could be hardly influenced by the formation of nanoparticles. ©2013 Central South University Press and Springer-Verlag Berlin Heidelberg.

摘要：
A series of polyimide composites with various mass fractions of multi-walled carbon nanotubes (MWNTs) were prepared by in situ polymerization. To increase the chemical compatibility of carbon nanotubes with the polyimide matrix, MWNTs were treated with an acid mixture and sulfoxide chloride in turn. The modified MWNTs are dispersed homogeneously in the matrix while the structure of the PI and MWNTs are stable in the preparation process. The composite films hold preferable thermal stability the same as the pure PI. The composite films exhibited good thermomechanical properties. The storage modulus increased significantly by increasing MWNT content and decreasing the enhancement of temperature. The films' glass transition temperature increased with enhancing of MWNTs frictions. The dielectric constants of the composites decrease with increasing frequency and increase sharply with the adding of MWNTs, which is favorable for practical use in anti-static materials and embedded capacitors.

摘要：
A displacement method of detecting hydrogen sulfide in aqueous media based on complex L–Cu ensemble is developed. Once combined with Cu2+, complex L–Cu displayed high specificity for sulfide anion. Among the various anions, only sulfide anion induce the revival of fluoresecence of compound L, which is quenched by Cu2+, resulting in turn-on type sensing sulfide anion. Complex L–Cu exhibits a highly sensitive fluorescent response toward S2− by releasing compound L to give a remarkable change with 20-fold fluorescence intensity enhancement under 2 equivalent of S2− added in Tris–HCl/ DMF (20 mM, 6/4, v/v), and also exhibits a dynamic response range for S2− from 5×10−7 to 5×10−6 M, with a detection limit of 0.18 μM. In addition, the turn-on fluorescent change upon the addition of S2− is also applied in cell imaging.

摘要：
A novel water-compatible microporous and mesoporous hyper-cross-linked resin modified with phenolic hydroxyl group (named as GQ-03) was synthesized to remove aniline in aqueous solution as compared with XAD-4. The maximum adsorption capacity of GQ-03 emerged at the molecular state for both aniline and p-cresol while the pH dependency trend of aniline adsorbed onto XAD-4 was accordant with the dissociation curve of aniline. The ionic strength influenced the adsorption obviously. The pseudo-first-order rate equation could describe the adsorption process of aniline onto GQ-03 in two stages while this equation could characterize the entire adsorption process of XAD-4. The adsorption isotherms could be correlated to the Freundlich model, higher K F and n values for GQ-03 than XAD-4. The breakthrough capacity and the total adsorption capacity of GQ-03 and XAD-4 was up to 47.2 mg mL -1 and 28.3 mg mL -1 , 271.7 mg mL -1 and 115.6 mg mL -1 , respectively. The size matching between the pore diameter of GQ-03 and the molecular size of aniline, and hydrogen bonding between GQ-03 and aniline resulted in the larger adsorption capacity. © 2012 Elsevier B.V.

摘要：
A series of novel bis-Schiff base were synthesized from 1-aryl-3-methyl-4-benzoyl-5-pyrazolones and diethylenetriamine (or triethylenetetramine) as the starting materials. All of these bis-Schiff bases were characterized by means of NMR, IR, and MS. The UV-vis absorption spectra and fluorescent spectra of these bis-Schiff bases were also measured. Moreover, the B3LYP/6-31G(d) method was used to optimize the ground state geometry of the bis-Schiff bases; and the UV-vis spectroscopic properties of the products were computed and compared with corresponding experimental data based on cc-pVDZ basis set of TD-B3LYP method. It has been found that all of these bis-Schiff bases show a remarkable absorption peak in a wavelength range of 270-340 nm; and their maximum emission peaks are around 348 nm.

摘要：
A novel hyper-cross-linked polymeric adsorbent modified with acetylaniline as the cross-linked bridge (denoted GQ-02) was synthesized for the enhanced removal of bisphenol A (BPA) from aqueous solution. Its chemical structure and pore structure were characterized by infrared spectroscopy and surface area analysis. Results showed that the adsorption capacity of BPA onto GQ-02 was larger than that of the commercial resins NDA-150, H103, NDA-88, NDA-99, and XAD-4 due to the cross-linked bridge of acetylaniline uploaded on GQ-02 resin. The solution pH had no significant effect on the adsorption capacity until it was higher than 6.39. The adsorption rate of GQ-02 was greater than that of H103 because of the longer cross-linked bridge between two benzene rings. The adsorption isotherms could be correlated to the Langmuir equation. More favorable adsorption of BPA onto GQ-02 than H103 was further demonstrated by thermodynamic analysis. Nearly 100% regeneration efficiency for GQ-02 was achieved by 80% ethanol and 0.5. mol/L NaOH. © 2012.

摘要：
The objective of this work was to study the comparison of the adsorption performances of phenol in aqueous solution onto H103 resin and XAD-4 resin. Experimental results showed that the molecular form of phenol is favorable for the adsorption. The adsorption capacity of phenol onto H103 was much larger than that of XAD-4 due to its average pore diameter. The pseudo-first-order rate equation can characterize the adsorption of phenol onto H103 and XAD-4. The rate constant k<inf>1</inf> for XAD-4 is greater than the one of H103 at the same condition, consistent with the shorter required time for XAD-4. ©(2012) Trans Tech Publications, Switzerland.

摘要：
A new effective fluorescent sensor based on rhodamine was synthesized, which was induced by Cu<sup>2</sup> in aqueous media to produce turn-on fluorescence. The new sensor 1 exhibited good selectivity for Cu<sup>2</sup> over other heavy and transition metal (HTM) ions in H<inf>2</inf>O/CH <inf>3</inf>CN(7:3, v/v). Upon addition of Cu<sup>2</sup>, a remarkable color change from colorless to pink was easily observed by the naked eye, and the dramatic fluorescence turn-on was corroborated. Furthermore, kinetic assay indicates that sensor 1 could be used for real-time tracking of Cu<sup>2</sup> in cells and organisms. In addition, the turn-on fluorescent change upon the addition of Cu<sup>2</sup> was also applied in bioimaging. ©2012 Elsevier B.V. All rights reserved.

摘要：
Industrial waste water with high levels of lead has serious threat to human health and other organisms. Power generation methods were used for recycling of lead. Some factors such as temperature, power generation time, the anode material, type and concentration of anode area solution on the power generation process were studied to find the optimal process parameters. The experimental results show that: in the optimum conditions, the recovery rate of lead was more than 90% and the lead concentration in waste water has reached the discharge standard. This method does not produce by-products of environmental pollution in the power generation process and needn't external supply of energy but produce certain energy. So it is a green chemistry technology. ©(2012) Trans Tech Publications.

摘要：
Cerium and nitrogen co-doped TiO<inf>2</inf> nanocrystals were synthesized by a simple sol-gel process, using tetrabutyl titanate as the raw materials with (NH<inf>4</inf>)<inf>2</inf>Ce(SO<inf>4</inf>)<inf>3</inf> and urea as ion donors. The co-doped TiO<inf>2</inf> nanoparticles were characterized by X-ray diffraction and transmission electro microscopy. The photodegradation of glyphosate has been investigated in aqueous suspensions of doped TiO<inf>2</inf> under visible irradiation. The results exhibit a higher thermal stability of anatase than pure TiO<inf>2</inf>. The uniform test results show the optimal conditions: n<inf>Ce</inf>/n<inf>Ti</inf> n<inf>N</inf>/n<inf>Ti</inf> and calcining temperature was 0.08, 0.01 and 800°C. The highest degradation rate for co-doped TiO<inf>2</inf> show five times photocatalytic activity of Degussa P25. ©(2012) Trans Tech Publications.
