| 1 | Reliable and Load Balance-Aware Multi-Controller Deployment in SDN显示文摘Software Defined Networking(SDN) provides flexible network management by decoupling control plane and data plane. However, such separation introduces the issues regarding the reliability of the control plane and controller load imbalance in the distributed SDN network, which will cause the low network stability and the poor controller performance. This paper proposes Reliable and Load balance-aware Multi-controller Deployment(RLMD) strategy to address the above problems. Firstly, we establish a multiple-controller network model and define the relevant parameters for RLMD. Then, we design the corresponding algorithms to implement this strategy. By weighing node efficiency and path quality, Controller Placement Selection(CPS) algorithm is introduced to explore the reliable deployments of the controllers. On this basis, we design Multiple Domain Partition(MDP) algorithm to allocate switches for controllers according to node attractability and controller load balancing rate, which could realize the reasonable domain planning. Finally, the simulations show that, compared with the typical strategies, RLMD has the better performance in improving the reliability of the control plane and balancing the distribution of the controller loads. | Tao Hu Peng Yi Jianhui Zhang Julong Lan | 2018 | China Communications2018，15，11： | 6 |
| 2 | A Distributed Decision Mechanism for Controller Load Balancing Based on Switch Migration in SDN显示文摘Software Defined Networking(SDN) provides flexible network management by decoupling control plane from data plane. And multiple controllers are deployed to improve the scalability and reliability of the control plane, which could divide the network into several subdomains with separate controllers. However, such deployment introduces a new problem of controller load imbalance due to the dynamic traffic and the static configuration between switches and controllers. To address this issue, this paper proposes a Distribution Decision Mechanism(DDM) based on switch migration in the multiple subdomains SDN network. Firstly, through collecting network information, it constructs distributed migration decision fields based on the controller load condition. Then we choose the migrating switches according to the selection probability, and the target controllers are determined by integrating three network costs, including data collection, switch migration and controller state synchronization. Finally, we set the migrating countdown to achieve the ordered switch migration. Through verifying several evaluation indexes, results show that the proposed mechanism can achieve controller load balancing with better performance. | Tao Hu Peng Yi Jianhui Zhang Julong Lan | 2018 | China Communications2018，15，10： | 6 |
| 3 | Phosphonate-Decorated Covalent Organic Frameworks for Actinide Extraction: A Breakthrough Under Highly Acidic Conditions显示文摘Although solid-phase extraction is a useful approach for metal ion separation from aqueous solutions,existing sorbents suffer from low extraction effici-encies and/or instability when in contact with strong acidic media.We report here the first study on rational design and fabrication of phosphonate-decorated covalent organic frameworks,COF-IHEP1 and COF-IHEP2,for efficient and selective extraction of of uranium(VI)[U(VI)]and plutonium(IV)[Pu(IV)]from highly acidic solutions. | Jipan Yu Liyong Yuan Shuai Wang Jianhui Lan Lirong Zheng Chao Xu Jing Chen Lin Wang Zhiwei Huang Wuqing Tao Zhirong Liu Zhifang Chai John K.Gibson Weiqun Shi | 2019 | CCS Chemistry2019，1，3： | 3 |

| 9 | Construction of hierarchically porous metal-organic framework particle by a facile MOF-template strategy显示文摘Increasing the mass diffusion efficiency is a major challenge in the realm of metal-organic frameworks(MOFs).Construction of hierarchically porous,typically microporous MOF adsorbents or catalysts is crucial for enhancing both mass transfer and molecular accessibility.Many strategies have been proposed for the synthesis of hierarchically porous MOFs(HP-MOFs),with some striking results.In this paper,we proposed a facile and versatile strategy,termed the MOF-Template strategy,for fabricating hierarchical pores in MOF particle.The highly controlled crystalline sizes and morphologies of the unstable Cu-MOFs Cu_(3)(BTC)_(2) and Cu(Qc)_(2) have been exploited in their utilization as sacrificial agents by uniformly dispersing them during the shaping process of ZIF-8.Through a facile treatment with alkaline solution,tunable mesopores and macropores could be easily introduced in the shaped ZIF-8 spheres.This strategy could effectively improve the adsorption kinetics and separation productivity of MOF materials while maintaining high mechanical stability,offering promising prospects for industrial application. | Tianhao Lan Qi Wang Chunyu Lu Jianhui Li Jinlong Li Yang Chen Libo Li Jiangfeng Yang Jinping Li | 2023 | Particuology2023，，3： | 1 |
| 10 | Temperature-responsive alkaline aqueous biphasic system for radioactive wastewater treatment显示文摘The treatment of anionic ^(99)TcO_(4)^(-)in the waste tank with high alkalinity is still very challenging.In this work,a new temperature-responsive alkaline aqueous biphasic system(ABS)based on(tri-n–butyl)-ntetradecyl phosphonium chloride(P_(44414)Cl)was developed to remove radioactive ^(99)TcO_(4)^(-).The phase transition mechanism was studied by cloud point titration,small-angel X-ray scattering,dynamic light scattering,and molecular dynamic simulations.As the Na OH concentration or temperature increased,the P_(44414)^(+)micelle could grow and aggregate.This micelle showed a particularly high affinity toward ReO_(4)^(-)/^(99)TcO_(4)^(-)compared to other competing anions and could directly extract more than 98.6%of ^(99)TcO_(4)^(-)from simulated radioactive tank waste supernatant.Furthermore,the loaded ^(99)TcO_(4)^(-)could be easily stripped by using concentrated nitric acid rather than metal salt-based reductants.This work clearly demonstrates that the alkaline ABS is a promising separation system for solving the technetium problem in the alkaline waste tank. | Chuanying Liu Jianhui Lan Qibin Yan Zhipeng Wang Chao Xu Weiqun Shi Chengliang Xiao | 2022 | Chinese Chemical Letters2022，33，7： | 0 |
| 11 | Theoretical investigation on the solution behaviors of Ba and Zr in uranium dinitride显示文摘The in-pile performance of ceramic fuels is significantly affected by the fission products. In this work, we have performed first-principles density functional theoretical calculations to study the interaction between metallic fission products(barium and zirconium) and the uranium dinitride UN2 matrix. The thermodynamic properties and bonding nature of Ba and Zr atoms in different incorporation configurations indicate that Zr is more soluble in UN2 matrix than Ba. With increasing the concentration of the impurity atoms, Zr-doped UN2 exhibits a slight tendency to contract, while Ba-doped UN2 tends to swell. Based on the competition between steric effect and chemical interaction, various incorporation trends for Ba and Zr in UN2 as well as in UN have been understood. | Yujuan Zhang Jianhui Lan Qunyan Wu Congzhi Wang Tao Bo Zhifang Chai Weiqun Shi | 2015 | Science China(Information Sciences)2015，58，12： | 0 |
| 12 | Theoretical studies on the complexation of Eu(Ⅲ) and Am(Ⅲ) with HDEHP: structure, bonding nature and stability显示文摘Separation of trivalent lanthanides(Ln(Ⅲ)) and actinides(An(Ⅲ)) is a key issue in the advanced spent nuclear fuel reprocessing. In the well-known trivalent actinide lanthanide separation by phosphorus reagent extraction from aqueous komplexes(TALSPEAK) process, the organophosphorus ligand HDEHP(di-(2-ethylhexyl) phosphoric acid) has been used as an efficient reagent for the partitioning of Ln(Ⅲ) from An(Ⅲ) with the combination of a holdback reagent in aqueous lactate buffer solution. In this work, the structural and electronic properties of Eu^(3+) and Am^(3+) complexes with HDEHP in nitric acid solution have been systematically explored by using scalar-relativistic density functional theory(DFT). It was found that HDEHP can coordinate with M(Ⅲ)(M=Eu, Am) cations in the form of hydrogen-bonded dimers HL_2^-(L=DEHP), and the metal ions prefer to coordinate with the phosphoryl oxygen atom of the ligand. For all the extraction complexes, the metal-ligand bonds are mainly ionic in nature. Although Eu(Ⅲ) complexes have higher interaction energies, the HL_2^- dimer shows comparable affinity for Eu(Ⅲ) and Am(Ⅲ) according to thermodynamic analysis, which may be attributed to the higher stabilities of Eu(Ⅲ) nonahydrate. It is expected that this work could provide insightful information on the complexation of An(Ⅲ) and Ln(Ⅲ) with HDEHP at the molecular level. | juan luo congzhi wang jianhui lan qunyan wu yuliang zhao zhifang chai changming nie weiqun shi | 2016 | Science China Chemistry2016，59，3： | 0 |
