摘要：
Due to the rapid development of the nuclear power industry, and consequently, the nuclear accident in Fukushima, much attention has been paid to novel materials for the efficient and rapid separation, removal and recovery of nuclear fuel associated radionuclides from aqueous solutions. Herein, a novel mesoporous material, dihydroimidazole functionalized SBA-15 (DIMS), was synthesized via a post-grafting method and used as an efficient sorbent for the extraction of U(VI) from aqueous solution. The synthesized material was found to possess highly ordered mesoporous structures with a large surface area and a uniform pore diameter. The sorption tests under various conditions demonstrated that the sorption of U(VI) by DIMS was fast, with an equilibrium time of less than 10 min. Additionally, the maximum sorption capacity reached 268 mg g−1 at pH 5.0 ± 0.1. Changes in the solid-to-liquid ratio (msorbent/Vsolution) did not have any remarkable effect on the U(VI) sorption. Besides, the sorbed U(VI) can be easily desorbed by 0.01 mol L−1 or more concentrated HNO3 solution, resulting in a U(VI) solution with a concentration factor of 300 at a solid–liquid ratio as low as 0.013 g L−1. The reclaimed sorbent can be reused with no obvious decrease in the sorption capacity. The selectivity of the DIMS sorbent for U(VI) ions was found to be fairly desirable by the sorption tests with the solutions containing a range of competing metal ions.

摘要：
Restructuring-induced catalytic activity is an intriguing phenomenon of fundamental importance to rational design of high-performance catalyst materials. We study three copper-complex materials for electrocatalytic carbon dioxide reduction. Among them, the copper(II) phthalocyanine exhibits by far the highest activity for yielding methane with a Faradaic efficiency of 66% and a partial current density of 13 mA cm−2 at the potential of – 1.06 V versus the reversible hydrogen electrode. Utilizing in-situ and operando X-ray absorption spectroscopy, we find that under the working conditions copper(II) phthalocyanine undergoes reversible structural and oxidation state changes to form ~ 2 nm metallic copper clusters, which catalyzes the carbon dioxide-to-methane conversion. Density functional calculations rationalize the restructuring behavior and attribute the reversibility to the strong divalent metal ion–ligand coordination in the copper(II) phthalocyanine molecular structure and the small size of the generated copper clusters under the reaction conditions. The catalytic conversion of carbon dioxide into value-added products requires an understanding of the active species present under working conditions. Here, the authors discover copper-containing complexes to reversibly transform during electrocatalysis into methane-producing copper nanoclusters.

摘要：
Evidences indicate that a complex relationship exists among sleep disorders, obesity and insulin resistance. NEU-P11 is a novel melatonin agonist used in treatment of psychophysiological insomnia, and in animal studies NEU-P11 showed sleep-promoting effect. In this study, we applied NEU-P11 on obese rats to assess its potential melatoninergic effects in vivo. Obese models were established using high-fat/high-sucrose-fed for 5 months. NEU-P11 (10 mg/kg)/melatonin (4 mg/kg)/vehicle were administered by a daily intraperitoneal injection respectively for 8 weeks. Our results showed that NEU-P11 or melatonin inhibited both body weight gain and deposit of abdominal fat with no influence on food intake. The impaired insulin sensitivity and antioxidative potency were improved and the levels of plasma glucose, total cholesterol (TC), triglycerides (TG) decreased with an increased in HDL-cholesterol (HDL-c) after NEU-P11 or melatonin administration. These data suggest that NEU-P11, like melatonin, decreased body weight gain and improved insulin sensitivity and metabolic profiles in obese rats. We conclude that NEU-P11 has a melatoninergic effect on regulating body weight in obese rats and also improving metabolic profiles and efficiently enhancing insulin sensitivity.

摘要：
A sensitive and selective electrochemical sensor for metronidazole (MNZ) was developed. The core–shell metronidazole-magnetic molecularly imprinted polymer (MMIP) was synthesized and then attached to the surface of magnetic glassy carbon electrode (MGCE) with the help of magnetic force in order to prepare MMIP/MGCE sensor. The performance of the obtained imprinted sensor was investigated by cyclic voltammetry and electrochemical impedance spectroscopy. Various factors, known to affect the response behavior of the MMIP/MGCE electrode, were studied and optimized. The imprinted sensor exhibits high recognition ability and affinity for MNZ in comparison with the nonimprinted one. In addition, the MMIP/MGCE also shows good stability and acceptable reproducibility for the determination of MNZ. Under the optimal experimental conditions, the current response of the electrochemical sensor was linear to MNZ concentrations in the range from 5.0 × 10−8 to 1.0 × 10−6 M, with the detection limit of 1.6 × 10−8 M. The method was successfully applied to the analysis of MNZ in milk samples and honey samples with acceptable recoveries of 93.5–102.2%.

摘要：
Artificial metalloenzymes combine the advantages of both natural enzymes and chemically synthesized models, which have achieved significant progress in the last decade. This review summarizes the recent achievements in rational design of metalloenzymes from single to multiple active sites in natural or de novo protein scaffolds, with a diverse range of functionalities, even beyond those of natural metalloenzymes. These achievements include construction of mononuclear active site by metal substitution or incorporation, design of homo- or hetero-dinuclear site, introduction of Fe-sulfur or other metal clusters, reconstitution of metallo-porphyrins or other metal complexes, and design of dual or multiple active sites in single, dimeric proteins, de novo proteins, protein-protein interfaces, as well as protein oligomers and polymers. Other new trends in recent designs are also discussed. The progress not only elucidates the structural and functional relationship of natural metalloenzymes, but also provides practical clues for design of advanced artificial metalloenzymes with potential applications.

摘要：
Uranium is one of the most hazardous heavy metal due to its long half-life radioactivity, high toxicity and mobility as aqueous uranyl ion (UO2 2+) under ordinary environmental conditions. Herein, amino functionalized SBA-15 (APSS) was developed as a rapid and efficient sorbent for removal of U(VI) from the environment. The APSS sample was synthesized by grafting method and was characterized by SEM, NMR, SAXS, and N2 sorption/desorption isothermal experiments. The sorption of U(VI) by APSS was investigated under different conditions of pH, contact time, initial U(VI) concentration, ionic strength and solid–liquid ratio. The results show that the sorption of U(VI) by APSS is strongly dependent on pH but independent of ionic strength and solid–liquid ratios (m/V). The sorption is ultrafast with an equilibrium time of less than 30 min, and the sorption capacity is as large as 409 mg/g at pH 5.3 ± 0.1. Besides, the U(VI) sorption by APSS from extremely diluted solution and the desorption of U(VI) from APSS were also studied. It is found that 100 mg of APSS can almost completely remove the U(VI) ions from 4 L aqueous solution with the U(VI) concentration as low as 4.2 ppb and the sorbed U(VI) can be completely desorbed by 0.1 mol/L nitric acid. The results strongly reveal the high performance of the APSS material in the removal and preconcentration of U(VI) from the aqueous solution.

摘要：
With the fast development of nanoscience and nanotechnology, the nanomaterials have attracted multidisciplinary interests. The high specific surface area and large numbers of oxygen-containing functional groups of graphene oxides (GOs) make them suitable in the preconcentration and solidification of radionuclides from wastewater. In this paper, mainly based on the recent work carried out in our laboratory, the efficient elimination of radionuclides using GOs and GO-based nanomaterials as adsorbents are summarized and the interaction mechanisms are discussed from the results of batch techniques, surface complexation modeling, spectroscopic analysis and theoretical calculations. This review is helpful for the understanding of the interactions of radionuclides with GOs and GO-based nanomaterials, which is also crucial for the application of GOs and GO-based nanomaterials in environmental radionuclide pollution management and also helpful in nuclear waste management.
