| 1 | Preparation of lignin/TiO2 nanocomposites and their application in aqueous polyurethane coatings显示文摘A simple method using a water soluble lignin quaternary ammonium salt (LQAS) and TiO2 has been developed for the preparation of lignin/TiO2 nanocomposites in an aqueous medium under mild conditions. The LQAS/TiO2 nanocomposites contain well-dispersed small particles with excellent ultraviolet (UV) shielding abilities and good compatibilities with waterborne polyurethane (WPU). When the LQAS/TiO2 nanocomposites were blended with WPU, the UV absorbance and the tensile ductility of the WPU increased significantly. The composite WPU hybrid film containing 6 wt-% LQAS/TiO2 nanocomposite had the highest visible light transmittance and had excellent ultraviolet aging properties. After 192 h of UV light irradiation, the tensile strength of the composite film was above 8 MPa and the elongation at break was 800%. This work highlights new possibilities for the utilization of alkali lignin. | Dongjie Yang Shengyu Wang Ruisheng Zhong Weifeng Liu Xueqing Qiu | 2019 | Frontiers of Chemical Science and Engineering2019，13，1： | 5 |
| 2 | Multi-energy Demand Response Management in Energy Internet: A Stackelberg Game Approach显示文摘A multi-energy Demand response management(DRM) approach in Energy Internet is proposed by employing Stackelberg game theory. The multi-energy trading problem in DRM is formulated as a Stackelberg game, where an energy provider, as a leader, adjusts energy prices, and residential smart energy hubs, as followers, dynamically schedule multiple energy flows according to the prices. The existence and uniqueness of the equilibrium of the proposed game model are analyzed.A multi-energy DRM algorithm for reaching the game equilibrium is developed. Simulation results show that the proposed game-based approach can effectively reduce residential energy costs and improve revenues of the energy provider. | WU Jie ZHOU Wenhui ZHONG Weifeng LIU Jinhua | 2019 | Chinese Journal of Electronics2019，28，3： | 2 |

| 4 | Electricity Consumption Scheduling with Consumers' Comfort and Preference in Smart Grid显示文摘A game theory based scheduling method for household electricity consumption in smart grid is proposed in this paper. A non-cooperative game model is employed during the scheduling. All household consumers compete with each other and control their loads to maximize their payoffs. For solving the scheduling problem, we formulate the Utility optimization(UO) model, in which the electricity cost reduction and the improvement of consumers' comfort and preference are considered simultaneously. The System optimization(SO) model only minimizes the electricity cost when scheduling the consumers' electricity consumption. Then we compare and analyze the two models in numerical simulation. The existence and the uniqueness of Nash equilibrium for proposed game model are proved. Simulation results show that the UO model provides an effective scheduling approach to achieve higher comfort and preference and at the same time decrease the energy cost. | ZHOU Wenhui WU Jie ZHONG Weifeng ZOU Sheng | 2016 | Chinese Journal of Electronics2016，25，6： | 1 |
| 5 | Motion and removal behavior of inclusions in electrode tip during magnetically controlled electroslag remelting:X-ray microtomography characterization and modeling verification显示文摘Detailed three-dimensional(3 D)microtomography characterizations of inclusions in electrode matrix,mushy zone(MZ)and liquid melt film(LMF)were performed to elucidate the motion and removal behavior of inclusions in electrode tip during magnetically controlled electroslag remelting(MC-ESR)process.A transient 2 D numerical model was also built to verify the experimental results and proposed mechanisms.The number and size of inclusions exhibited an obvious increasing trend from edge to mid region in LMF,while remained almost the same in electrode matrix and MZ.The inclusions in LMF migrated from edge to mid region of LMF,accompanied with removal process.In addition,the kinetic conditions for inclusion migrating to LMF/slag interface(LSI)were enhanced during MC-ESR process,thereby improving the inclusion removal efficiency in LMF.This work highlights the 3 D characterization and motion/removal mechanisms of inclusions in electrode tip,as well as sheds new light on preparing high purity materials. | Yifeng Guo Zhibin Xia Qiang Li Mingyue Sun Weifeng Liu Shaogang Wang Zhe Shen Tianxiang Zheng Biao Ding Yunbo Zhong | 2022 | Journal of Materials Science & Technology2022，，1： | 1 |

| 8 | Improved Model of Radial Vibration in Switched Reluctance Motor Including Magnetic Saturation显示文摘This paper proposes an improved method for the prediction of radial vibration in switched reluctance motor(SRM)considering magnetic saturation.In this paper,the basic modeling principle is briefly introduced,it is based on the derivation that the peak acceleration is dependent on the product of phase current and current gradient idi/dt.However,the derivation may cause errors due to saturation effect.Thus in this paper,the discrete sample data are firstly acquired based on DC pulse measurement method,by which electromagnetic,torque and peak acceleration characteristics can all be acquired.Then the entire peak acceleration characteristics are obtained by improved Least Square Support Vector Machine(LSSVM).Based on the obtained static peak acceleration characteristics,the time-varied radial vibration model is established based on superposition of natural oscillations of dominant vibration modes.Finally,a simulation model is built up using MATLAB/Simulink.The good agreement between simulation and experiment shows that the proposed method for modeling is feasible and accurate,even under saturation.In addition,since LSSVM does not need any prior knowledge,it is much easier for modeling compared with other existing literatures. | Xiaoqiang Guo Rui Zhong Mingshu Zhang Desheng Ding Weifeng Sun | 2018 | CES Transactions on Electrical Machines and Systems2018，2，4： | 0 |

| 11 | Risk factors for post-hepatectomy liver dysfunction in primary liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis显示文摘Objective:The purpose of this study was to analyze risk factors for development of post-hepatectomy liver dysfunction in primary liver cancer(PLC)patients with concurrent hepatic schistosomiasis and chronic hepatitis.Methods:A retrospective analysis of 73 PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis,of which 16 patients developed liver dysfunction(persistent ascites or pleural effusion or occurrence of liver-related potentially fatal complications)following hepatectomy,was performed.After clinical characteristics were recorded,preoperative liver function parameters and surgery-related parameters in these patients were assessed.Seventeen potential risk factors for post-hepatectomy liver dysfunction were identified.The association between these potential risk factors and post-hepatectomy liver dysfunction then was analyzed.Results:Univariate analysis showed that liver cirrhosis,intraoperative blood loss,and preoperative total bilirubin were associated with the development of post-hepatectomy liver dysfunction.Multivariate logistic regression analysis of these three factors revealed that intraoperative blood loss≥600 mL and cirrhosis were two independent risk factors for post-hepatectomy liver dysfunction in PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis.Conclusion:Keeping intraoperative blood loss below 600 mL can help avoid the development of post-hepatectomy liver dysfunction in liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis.For patients with concomitant liver cirrhosis,every effort should be made to minimize potential liver function impairment induced by other adverse factors. | ZHANG Minfeng SHEN Weifeng ZHONG Wei LIU Qu SHEN Rongxi YANG Jiamei | 2013 | Journal of Medical Colleges of PLA(China)2013，28，4： | 0 |
| 12 | Papillary fibroblast-recruiting injectable self-healing multifunctional hydrogels for wound regeneration显示文摘The recruitment of key cells to regeneration sites is a promising strategy to promote functional wound healing.Dermal fibroblasts exhibit a heterogeneous population of cells during homeostasis and in response to injury.Papillary fibroblasts play central regulatory roles in the regeneration of skin appendages during wound healing.Inspired by the phenomenon where bait for grass carp can attract grouped grass carps to a fishing spot soon,“Grass Carp Fishing”multifunctional hydrogels,that is,codelivery of an antibody of leucine-rich repeats and immunoglobulin-like domains 1(Lrig1)on the surface of papillary fibroblasts and insulinlike growth factor 1(IGF1)with recruitment function,can recruit papillary fibroblasts.In the experiments,carboxymethyl chitosan showed positive effects in promoting cell proliferation and neovascularization,while dopamine-grafted gelatin was effective in stabilizing the structure and prolonging the degradation time.The sustained release of Lrig1 antibodies and IGF1 from injectable self-healing multifunctional hydrogels persistently accelerated the migration and proliferation of Lrig1+fibroblasts.The in vivo results from a full-thickness cutaneous wound model showed that injectable self-healing multifunctional hydrogel accelerated wound healing and skin regeneration through the recruitment of Lrig1+papillary fibroblasts in wound tissue.Our findings reveal an injectable self-healing multifunctional hydrogel for regeneration,a promising approach to promoting skin wound healing. | Yueyue Li Weifeng Zhong Junjie Wu Yuan Jia Zhonghua Chen Kaiwen Zhang Danyang Guo Yifei Fu Mengnan Chen Weiwei Chen Fan Tian Xia Li Hongji Zhang Xiaojin Zhou Feng-Lai Yuan | 2023 | Nano Research2023，16，7： | 0 |
