| 1 | A smart nanoprobe based on luminescent terbium metal-organic framework coated gold nanorods for monitoring and photo-stimulated combined thermal-chemotherapy显示文摘Real-time monitoring and accurate treatment are of great significance for reducing the side effects during the cancer therapy.In this work,we rationally prepared a smart nanoprobe based on core-shell terbium metal-organic gramework(MOF)with highly effective photothermal conversion capacity and drug release efficiency under near-infrared light irradiation for real-time fluorescence imaging-guided multimodal therapy.The nanoprobe can achieve prominent photothermal therapy and controllable drug release,act as a fluorescence thermometer,and also real-time feedback of temperature is expected to be achieved.At the same time,the two-photon ligand design significantly improves the tissue penetration ability of the nanoprobe.Our work is expected to provide a reference for precise treatment and real-time monitoring of tumors and at the same time provide new ideas for the formulation of individualized treatment plans. | Tong Zhang Liying Qin Liangliang Liu Meina Zhang Tianyi Du Yifan Fan Huicheng Yan Pingru Su Ping Zhou Yu Tang | 2022 | Journal of Rare Earths2022，40，9： | 0 |
| 2 | Relationship between reaction rate constants of organic pollutants and their molecular descriptors during Fenton oxidation and in situ formed ferric-oxyhydroxides显示文摘Fenton oxidation is a promising water treatment method to degrade organic pollutants. In this study, 30 different organic compounds were selected and their reaction rate constants(k) were determined for the Fenton oxidation process. Gaussian09 and Material Studio software sets were used to carry out calculations and obtain values of 10 different molecular descriptors for each studied compound. Ferric-oxyhydroxide coagulation experiments were conducted to determine the coagulation percentage. Based upon the adsorption capacity,all of the investigated organic compounds were divided into two groups(Group A and Group B). The percentage adsorption of organic compounds in Group A was less than 15%(wt./wt.)and that in the Group B was higher than 15%(wt./wt.). For Group A, removal of the compounds by oxidation was the dominant process while for Group B, removal by both oxidation and coagulation(as a synergistic process) took place. Results showed that the relationship between the rate constants(k values) and the molecular descriptors of Group A was more pronounced than for Group B compounds. For the oxidation-dominated process,EHOMOand Fukui indices(f(0)_x, f(-)_x, f(+)_x) were the most significant factors. The influence of bond order was more significant for the synergistic process of oxidation and coagulation than for the oxidation-dominated process. The influences of all other molecular descriptors on the synergistic process were weaker than on the oxidation-dominated process. | Lijuan Jia Zhemin Shen Pingru Su | 2016 | Journal of Environmental Sciences2016，28，5： | 0 |
