摘要：
In view of the few reports of the near-infrared emissive probe for fluorine ions, we herein designed and synthesized a new easy-to-get colorimetric and near-infrared emissive fluorescent probe (IS-NR-F) with a large Stokes shift (>127 nm). Based on specific F- triggered desilylation reaction induced enhanced ICT strategy involving the donor phenolate anion and the acceptor malononitrile, the probe exhibited dual colorimetric and fluorescent turn-on responses, and provided excellent selectivity for fluoride ions. The fluorescent response at 665 nm displayed very good linear relationship in the wide concentration range and deduced a low detection limit of 0.09 ppm. The detection mechanism was confirmed by H-1 NMR, ESIMS, and TLC calculation. Moreover, probe IS NR F has been successfully employed to detect F - in tap water, toothpaste samples, and fluorescent imaging of F- in HeLa cells. (C) 2019 Elsevier Ltd. All rights reserved.

摘要：
With rapid development of nuclear industry, the overexploitation of uranium has brought a series of radioactive pollution problems to water, soil, atmosphere and ecosystem. Uranium and its compounds are highly carcinogenic and biologically toxic, posing a deadly threat to human health. Therefore, how to design a highly selective and sensitive sensor to detect uranyl ions in the environment and organisms has become an urgent task. This review summarizes relevant literature on the detection of uranyl ions by different sensors over the years. The detection methods can be roughly divided into three categories: optical sensors, electrochemical sensors and other sensors; further classification has also been carried out according to their detection mechanism. The detection limits and performances of different sensors are discussed to intuitively understand different capability for these methods in detecting uranyl ions. We also discuss the trend and future direction of uranium to provide a valuable reference for further developing better uranyl sensors. © 2019 Elsevier B.V.

摘要：
Abstract: A novel Zn2+ fluorescent probe Nʹ-((4′-(diphenylamino)-4-hydroxy-[1,1′-biphenyl]-3-yl)methylene)-2-hydroxybenzohydrazide (TPA-HPH) with a larger Stokes shift (210nm) was designed and synthesized, which was seen to be highly selective and sensitive to Zn2+ ion over other metal ions in the system of MeCN:H2O (V/V = 6:4, pH = 7.0). Meanwhile, it was observed that the TPA-HPH solution changed from colorless to yellow by “naked eye” when Zn2+ was added. Under optimized conditions, the fluorescence intensity of the probe showed a good linear relationship with Zn2+ ion concentration in the range of 0–10μM with a low detection limit of 7.3 × 10−10M. The fluorescent mechanism was proposed. Most importantly, TPA-HPH could realize on-site monitor and live cell imaging for Zn2+ ion.

摘要：
采用基团贡献法(GC)和分子动力学法(MD)模拟了聚间苯二甲酰间苯二胺纤维(MPDI)和聚对苯二甲酰对苯二胺(PPTA)的玻璃化转变温度,并与实验值进行了对比.结果表明,使用基团贡献法和分子动力学法测得的MPDI和PPTA的玻璃化转变温度与实验值接近,说明基团贡献法和分子动力学法可以用来预测芳香族聚酰胺的玻璃化转变温度.在此基础上,采用GC和MD预测了聚间苯二甲酰对苯二胺(PPIA)的玻璃化转变温度.在MD模拟中,对密度、比体积、回转半径和非键相互作用随温度的变化规律进行了分析.结果表明,自由体积理论能较好地解释PPIA的玻璃化转变现象,其中非键相互作用随温度的变化是玻璃化转变的本质原因.PPIA的玻璃化转变温度介于MPDI和PPTA之间,有望成为综合性能介于两者之间的另一种高性能聚酰胺.

摘要：
With the increasing demand of nuclear power plant, the depleted uranium is inevitably emitted and causes environmental risk, hence it is crucial to develop new methods to efficiently eliminate uranium compounds from water. In this work, a bifunctional material core-shell-shell layered double hydroxide (LDH) decorated hollow magnetic polydopamine (MP) microspheres (defined as MPL) were synthesized and evaluated for the cleanup of uranium (VI) from aqueous solutions through specific adsorption. The experimental results showed that the adsorption was significantly affected by pH value rather than ionic strength, reflecting that the interaction was mainly governed by inner-sphere surface complexation owing to the multiple functional groups including imine, catechol, amine, and hydroxyl groups. The adsorption kinetics can be perfectly depicted by the pseudo-second-order model with high uptake percentage of 94.8%, which was superior to the previously reported materials. Interestingly, the maximum adsorption performance can be tuned by changing the thickness of polydopamine shell and the content of LDH, in the order of MP<inf>2</inf>L<inf>2</inf>(344 mg/g) >MP<inf>2</inf>L<inf>3</inf>(291 mg/g) >MP<inf>3</inf>L<inf>2</inf>(245 mg/g) >MP<inf>2</inf>L<inf>1</inf>(211 mg/g) >ML<inf>2</inf>(142 mg/g) >MP<inf>1</inf>L<inf>2</inf>(141 mg/g) >MP<inf>2</inf>(71 mg/g) >Fe<inf>3</inf>O<inf>4</inf>(34 mg/g) at 298.15 K and pH 5.0. The adsorption mechanism has been thoroughly investigated with techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), thermo-gravimetric analyses (TGA), Fourier transformed infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). In summary, the bifunctional material could be applied as promising building block for the enrichment and recovery of uranium (VI) from aqueous solutions in environmental pollution cleanup.<br/> ©2017 Elsevier Ltd

摘要：
Potentially toxic metals in sewage and industrial effluents pose a serious threat to human health and the environment. Herein, core-shell hollow magnetic polydopamine nanoparticles (denoted as Fe 3 O 4 @PDA) were fabricated via a simple one-pot synthesis method and applied for the elimination of Pb(ii) and Cu(ii) from wastewater. The versatile polydopamine (PDA) layer with abundant functional groups (amine, imine and catechol groups) provided favourable sites to bind metal ions. The experimental results showed that the adsorption processes were significantly affected by the pH values of the suspension. The ionic strength-independent adsorption processes indicated the existence of inner-sphere surface complexes of Pb(ii) and Cu(ii) on Fe 3 O 4 @PDA. The results showed that Fe 3 O 4 @PDA exhibited fast removal kinetics for Pb(ii) and Cu(ii), which achieved equilibrium within 3 h. The adsorption processes were well fitted by the pseudo-second-order kinetic model and Langmuir isotherm model. Furthermore, the removal capacities of Fe 3 O 4 @PDA were calculated to be 57.25 mg g -1 for Pb(ii) and 86.35 mg g -1 for Cu(ii), which were much higher than those of pure Fe 3 O 4 and other materials. Most importantly, the adsorption efficiencies of Pb(ii) and Cu(ii) on Fe 3 O 4 @PDA were still ∼71% and ∼70% after five cycles, respectively. In summary, the hollow Fe 3 O 4 @PDA nanoparticles can be used as outstanding materials for the elimination of Pb(ii) and Cu(ii), which is beneficial to reduce the toxic effects of heavy metal ion contaminated water. © the Partner Organisations.

摘要：
Nickel/cobalt double hydroxides with sphere-like nanoflowers and nanoporous structures were controllably prepared by introducing halide ions into the reaction system. The morphology and structure of the composites were characterized by X-ray diffraction, scanning electron microscope, infrared spectra and Brunauer-Emmett-Teller method. Halides, especially bromide, can dramatically affect the morphology of the crystal aggregates, and some morphology-dependent electrochemical properties are found. Nickel/cobalt double hydroxide, prepared in the presence of potassium bromide, exhibits excellent electrochemical performance. The composite's specific capacitance can reach 2630 F g-1 at a current density of 1 A g-1. Even at 8 A g-1, the composite can still retain 80.7% of its capacitance, which is much higher than that of nickel/cobalt double hydroxide prepared in the absence of bromide (68.6%). © 2018 The Authors.

摘要：
Abstract: An off–on colorimetric and fluorescent probe N1, N4-bis (2-(3′, 6′-bis(diethylamino)-3-oxospiro[isoindoline-1,9′-xanthen]-2-yl) ethyl) terephthalamide (Rp) for Fe3+ was designed and synthesized, which could selectively and sensitively respond to Fe3+ among other tested metal cations in THF–H2O solution (v/v = 4/6, pH = 7.2) accompanied with a remarkable fluorescence enhancement and an obvious color change visible to “naked-eye”. The fluorescence intensity of the probe Rp showed a good linearity with the concentration of Fe3+ covering from 0.1 to 26 μM and the detection limit was 0.0231 μM. Meanwhile, the binding mode between Rp and Fe3+ was found to be a 1:2 stoichiometric formation. Moreover, the complexation of Rp–Fe3+ could be broken by carbonate, so this system might be utilized as a carbonate probe in the future. Most importantly, the probe Rp was not only applied to monitor Fe3+ level in human blood serum and water samples, but also was used for fluorescence imaging of Fe3+ in living cell.

摘要：
Uranium was not only the main source of nuclear energy but also one of the long-lived radionuclide. Herein,a novel arginine modified hydroxyapatite carbon microsphere composites (defined as C@HAp/ Arg) obtained promptly via a one-step mild hydrothermal method,was applied to remove U(VI) from aqueous solutions. Based on the characterization of transmission electron microscopy (TEM),scanning electron microscopy (SEM),Fourier transformed infrared spectroscopy (FT-IR),X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS),the synthesized C@HAp/Arg presented globular morphology and abundant functional groups (e.g.,ACOO~-),which were beneficial to its combination with U(VI). The interaction mechanism and removal capability of U(VI) on C@HAp/Arg were studied by batch adsorption technique and spectroscopy analysis. The results implied that U(VI) can form strong surface complexes on C@HAp/Arg. The kinetics adsorption of U(VI) followed pseudo-second-order kinetic model with high removal efficiency (~95% within 5 h at pH 5.0). The adsorption isotherms were well fitted by Langmuir model,implying that U(VI) uptake on C@HAp/Arg was monolayer coverage. It was found that the maximum adsorption capacities of CSs,C@HAp and C@HAp/Arg toward U(VI) were calculated to be 23.16,72.09 and 569.66 mg/g,respectively,at 298.15 K and pH 5.0,and thermodynamic parameters revealed that the adsorption processes of U(VI) were spontaneous and endothermic. In addition,effect of co-existed ions and CO_3~(2-) concentrations demonstrated that U(VI) adsorption on C@HAp/Arg was weakly interfered by foreign ions and carbonate concentrations. More importantly,the adsorption performance of U(VI) on C@HAp/Arg was still over ~87% after five cycles. Therefore,it was noted that the versatile C@HAp/Arg could be potentially used as a powerful building block for the enrichment and disposal of U(VI) from aqueous solutions,which could efficiently reduce the potential toxicity of U(VI) in the U (VI)-contaminated water.

摘要：
A modified gelcasting approach was used to fabricate the microscale randomized 1–3 piezoelectric array, which involves the in situ polymerization of hydantion epoxy resin and 3,3′-Diaminodipropylamine (DPTA) in the lead zirconate titanate (PZT) suspensions with low viscosity and high solid loading. Rheological results demonstrated that the hydantion epoxy resin concentration had little effect on the viscosity of the premix solution, and therefore the optimized solid loading of the suspensions with 15.0 wt% resin could reach as high as 55.0 vol%. Weibull analysis also revealed that a more homogenous microstructure was obtained derived from the 55.0 vol% PZT suspension, where the Weibull modulus and the characteristic flexural strength reached the maximum value of 12.57 and 80.94 MPa. The excellent randomized piezoelectric pillar array with superior structural integrity and high fidelity was successfully fabricated. ©2016 Elsevier Ltd and Techna Group S.r.l.

摘要：
In this study, chitosan–metal oxide composites (CS–MO) were prepared for graphene oxide (GO) removal from aqueous solutions. The results showed that the GO coagulation on CS–MO was dependent on pH and ionic strength. The maximum GO removal capacities reached 442.5mg/g on CS–Al2O3, 425.0mg/g on CS–ZnO and 421.2mg/g on CS–MgO, respectively, showing a huge advantage in the efficient elimination of GO from natural water system. The coagulation of GO on CS–MO was dominated by electrostatic attraction in acidic conditions and by hydrogen bonds in neutral and alkaline conditions. The findings are helpful to improve the current understanding of the environmental behavior of GO in natural aqueous systems. © 2016, Springer Science+Business Media Dordrecht.

摘要：
Capacitive deionization (CDI) is a promising water desalination technology in which a pair of porous electrodes is electrically charged to remove ionic species from water. Rational design of electrode materials and device structure opens new possibilities in removing heavy metals from wastewater by the CDI process. Herein, a bench-scale CDI device based on 3D functionalized flexible carbonaceous aerogels (CAs) derived from natural and renewable biomass was designed for water decontamination. We put forward a new and promising fabrication method, which utilized only low valence metal precursors to fabricate high valence metal oxides (MO) and CA hybrids (denoted CAs/MO). The resultant CAs/MO hybrids exhibited a hierarchical porous structure with a specific surface area of 262.6 m2 g-1 and an excellent specific capacity of 120.4 F g-1. Enhanced electrochemical capacity and low inner resistance endowed the CAs/MO hybrid electrodes with an outstanding decontamination capacity of 57.13 mg g-1 for Cu(ii) at a low applied voltage of 1.2 V, which was nearly 3 times higher than that of 19.28 mg g-1 at an open circuit and highlighted the advantages of the CDI process in decontamination technology. The CAs/MO electrodes had good cycling stability for CDI decontamination applications. This study certifies the feasibility of decontamination and recovery of aqueous toxic heavy metals using the CDI process in pollution cleanup. © 2017 The Royal Society of Chemistry.

Layered double hydroxides;Methyl orange;SiO2@LDH;Sorption;U(VI)
摘要：
Hierarchical silicon dioxide-@-layered double hydroxide (SiO2@LDH) nanocomposites were synthesized by a facile in situ co-precipitation method, and characterized by XRD, FESEM, FT-IR and XPS in detail. The sorption of uranium (U(VI)) and methyl orange (MO) on SiO2@LDH were investigated as a function of pH, ionic strength, contact time and temperature. The results indicated that the sorption of U(VI) and MO were strongly dependent on pH, and weakly dependent on ionic strength, demonstrating that the interaction of U(VI) was mainly dominated by inner-sphere surface complexation and the sorption of MO was mainly attributed to electrostatic attraction due to the high removal efficiency (∼98% within 4h for U(VI) ions, and ∼92% within 10min for MO). The kinetics sorption of U(VI) and MO both followed the pseudo-second-order model well, suggesting that the sorption processes were chemical sorption. The sorption isotherms of U(VI) and MO on SiO2@LDH were well fitted by the Langmuir model, and the maximum sorption capacities of SiO2@LDH were calculated to be 303.1mg·g−1 for U(VI) and 166.1mg·g−1 for MO. The thermodynamic parameters revealed that the sorption of U(VI) and MO was spontaneous process. Integrating the experimental result analysis, the hierarchical SiO2@LDH may be a promising material for the efficient elimination of radionuclides and dyes from aqueous solutions in natural environmental pollution cleanup. © 2017

摘要：
Novel rod-like ternary nanoscale layered double hydroxides (Ca-Mg-Al-LDH) and their bimetal derivatives (Ca-Mg-Al-LDOx, x: 200, 300, 400, 500, and 600 °C) were fabricated with a simple-green hydrothermal and calicination process. The interaction mechanism and adsorption property of U(VI) on Ca-Mg-Al-LDH and Ca-Mg-Al-LDOx were investigated by a batch technique and spectroscopy analysis, and the results indicated that U(VI) could form strong and stable surface complexes on Ca-Mg-Al-LDH and Ca-Mg-Al-LDOx surfaces. The adsorption capacity of U(VI) on various adsorbents could be controlled and adjusted through changing the calcination temperature, which was attributed to the different contents of various metal-oxide bonds (e.g., Ca-O, Mg-O, and Al-O). The adsorption capacities of U(VI) on these adsorbents were in the order of Ca-Mg-Al-LDO<inf>500</inf>(486.8 mg/g) >Ca-Mg-Al-LDO<inf>600</inf>(373.4 mg/g) >Ca-Mg-Al-LDO<inf>400</inf>(292.5 mg/g) >Ca-Mg-Al-LDO<inf>300</inf>(260.0 mg/g) >Ca-Mg-Al-LDO<inf>200</inf>(223.5 mg/g) >Ca-Mg-Al-LDH (132.5 mg/g), which might be attributed to more active surface sites and abundant "Ca-O and Al-O" with the increase of calcination temperature. The results of kinetic and thermodynamic studies demonstrated that the adsorption was a spontaneous and endothermic chemical process, and the better fitted Sips model revealed that the adsorption reaction was multilayer adsorption at low concentration of U(VI) and monolayer adsorption at high concentration of U(VI). This study provided highlights on the interaction mechanism of U(VI) with various metal-oxide bonds, and it could play an important role for the controllable adsorption capacity and effcient application in environmental remediation. ©2016 American Chemical Society.
