| 1 | Thermally conductive polyvinyl alcohol composite films via introducing hetero-structured MXene@silver fillers显示文摘Ag nanoparticles were in-situ grown on the surface of MXene nanosheets to prepare thermally conductive hetero-structured MXene@Ag fillers.With polyvinyl alcohol(PVA)as the polymer matrix,thermally conductive MXene@Ag/PVA composite films were fabricated by the processes of solution blending,pouring,evaporative self-assembly.With the same mass fraction,MXene@Ag-III(MXene/Ag,2:1,w/w)presents more significant improvement in thermal conductivity coefficient(λ)than MXene@Ag,single MXene,Ag,simply blending MXene/Ag.MXene@Ag-III/PVA composite films show dual functions of excellent thermal conductivity and electromagnetic interference(EMI)shielding.When the mass fraction of MXene@Ag-III is 60 wt.%,the in-planeλ(λ_(∥)),through-planeλ(λ_(⊥)),EMI shielding effectiveness(EMI SE)are 3.72 and 0.41 W/(m∙K),32 dB,which are increased by 3.1,1.3,105.7 times than those of pure PVA film(0.91 and 0.18 W/(m∙K),0.3 dB),respectively.The 60 wt.%MXene@Ag-III/PVA composite film also has satisfying mechanical and thermal properties,with Young’s modulus,glass transition temperature,heat resistance index of 3.8 GPa,58.5 and 175.3℃,respectively. | Mukun Li Yuyao Sun Dianying Feng Kunpeng Ruan Xia Liu Junwei Gu | 2023 | Nano Research2023，16，5： | 10 |
| 2 | Novel Cascaded Z-Source Neutral Point Clamped Inverter显示文摘Z-source Neutral point clamped(NPC) inverter inherits the advantages of Z-source inverter, which can buck-boost energy and allow the shoot-through states.At the same time, Z-source NPC inverter has high running efficiency and less harmonic content. Hence, it can be widely used in motor drives and fuel cell applications.When increasing the modulation index, one can only get smaller shoot through value in Z-source NPC inverter,therefore the output voltage of the inverter can not be boosted very high. In this paper, a novel cascaded Z-source neutral point clamped inverter is proposed by cascading two Z-source networks in series. An Alternative phase opposition disposition(APOD) carrier-based modulator is applied to control the proposed Z-source inverter. To confirm the operating principle of the new Z-source NPC inverter, a generic APOD carrier-based modulator for the cascaded Z-source NPC Inverter under Matlab/Sinmulink is built. The simulation results show that the boost factor has been increased from 1/(1- 2D) for the traditional Z source NPC inverter to 1/(1- 4D) for the proposed cascaded Z-source NPC inverter. A prototype of the cascaded Z-source NPC inverter has been set up. The experimental results verify that the new topology can increase the boost factor and expand the voltage regulation range of the inverter. | HE Yuyao LIU Hailong FENG Wei LI Jie | 2016 | Chinese Journal of Electronics2016，25，5： | 2 |
| 3 | A fast boundary protection for an AC transmission line connected to an LCCHVDC inverter station显示文摘For AC transmission lines connected to an LCC-HVDC inverter station,commutation failure can lead to the wrong operation of traditional protection.To solve the problem,this paper proposes a fast protection scheme using transient information from one end of the AC line.The boundary frequency characteristics of the AC line connected to LCC-HVDC inverter are analyzed first.This reveals the existence of significant attenuation on both high frequency signals and some specific frequency signals.Based on the boundary characteristics,a novel boundary protection principle utilizing a backward traveling wave is then proposed.A PSCAD/EMTDC simulation model of a±800 kV LCC-HVDC and 500 kV AC transmission system is established,and different fault cases are simulated.The simulation results prove that the novel protection principle is immune to commutation failure,fault resistance and fault type. | Zhen Liu Houlei Gao Sibei Luo Le Zhao Yuyao Feng | 2020 | Protection and Control of Modern Power Systems2020，5，1： | 2 |

| 5 | ROS is essential for initiation of energy deprivation-induced autophagy显示文摘Autophagy is a highly conserved degradation process in which intracellular components are engulfed into a double membrane structure,known as the autophagosomes,and then delivered to lysosomes/vacuoles for degradation(Ohsumi,2014).Recently,autophagy has been found to be responsible for maintaining glucose homeostasis in adult animals(Karsli-Uzunbas et al.,2014).However,the molecular mechanism underlying energy deprivation-induced autophagy remains relatively unclear. | Choufei Wu Yixing Li Shu Zhong Yingcong Chen Yu Xie Yuyao Feng Weijing Yao Suping Fu Yanlan Zhu Liefeng Wang Yuting Chen Liqin Zhang Jingjing Tong Cong Yi | 2021 | Journal of Genetics and Genomics2021，48，6： | 1 |

| 7 | HDAC I/IIb selective inhibitor Purinostat Mesylate combined with GLS1 inhibition effectively eliminates CML stem cells显示文摘Purinostat Mesylate(PM)is a novel highly selective and active HDAC I/IIb inhibitor,and the injectable formulation of PM(PMF)based on the compound prescription containing cyclodextrin completely can overcome PM’s poor solubility and improves its stability and pharmacokinetic properties.Here,we showed that PM effectively repressed the survival of Ph+leukemia cells and CD34+leukemia cells from CML patients in vitro.In vivo studies demonstrated that PMF significantly prevented BCR-ABL(T315I)induced CML progression by restraining leukemia stem cells(LSCs),which are insensitive to chemotherapy and responsible for CML relapse.Mechanism studies revealed that targeting HDAC I/IIb repressed several important factors for LSCs survival including c-Myc,β-Catenin,E2f,Ezh2,Alox5,and mTOR,as well as interrupted some critical biologic processes.Additionally,PMF increased glutamate metabolism in LSCs by increasing GLS1.The combination of PMF and glutaminase inhibitor BPTES synergistically eradicated LSCs by altering multiple key proteins and signaling pathways which are critical for LSC survival and self-renewal.Overall,our findings represent a new therapeutic strategy for eliminating LSCs by targeting HDAC I/IIb and glutaminolysis,which potentially provides a guidance for PMF clinical trials in the future for TKI resistance CML patients. | Qiang Qiu Linyu yang Yunyu Feng Zejiang Zhu Ning Li Li Zheng Yuanyuan Sun Cong Pan Huandi Qiu Xue Cui Wei He Fang Wang Yuyao Yi Minghai Tang Zhuang Yang Yunfan Yang Zhihui Li Lijuan Chen Yiguo Hu | 2023 | Bioactive Materials2023，，3： | 1 |
| 8 | Intercellular mitochondrial transfer as a means of tissue revitalization显示文摘As the crucial powerhouse for cell metabolism and tissue survival,the mitochondrion frequently undergoes morphological or positional changes when responding to various stresses and energy demands.In addition to intracellular changes,mitochondria can also be transferred intercellularly.Besides restoring stressed cells and damaged tissues due to mitochondrial dysfunction,the intercellular mitochondrial transfer also occurs under physiological conditions.In this review,the phenomenon of mitochondrial transfer is described according to its function under both physiological and pathological conditions,including tissue homeostasis,damaged tissue repair,tumor progression,and immunoregulation.Then,the mechanisms that contribute to this process are summarized,such as the trigger factors and transfer routes.Furthermore,various perspectives are explored to better understand the mysteries of cell-cell mitochondrial trafficking.In addition,potential therapeutic strategies for mitochondria-targeted application to rescue tissue damage and degeneration,as well as the inhibition of tumor progression,are discussed. | Delin Liu Youshui Gao Jiao Liu Yigang Huang Junhui Yin Yuyao Feng Linjing Shi Bruno PMeloni Changqing Zhang Minghao Zheng Junjie Gao | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 0 |
| 9 | Practical Realization of Optimal Auxiliary Frequency Control Strategy of Wind Turbine Generator显示文摘Adding the auxiliary frequency control function to the wind turbine generator(WTG)is a solution to the frequency security problem of the power system caused by the replacement of the synchronous generator(SG)by the WTG.The auxiliary frequency control using rotor kinetic energy is an economical scheme because the WTG still runs at the maximum power point during normal operation.In this paper,the functional optimization model of the auxiliary frequency control strategy of WTG is established.The optimal auxiliary frequency control strategy is obtained by solving the model numerically.As for the practical realization of the control strategy,the coordination of the auxiliary frequency control with the maximum power point tracking(MPPT)control is studied.The practical auxiliary frequency control strategy is modified to adapt to different power disturbances in the system,and the parameter setting method is also proposed.The sensitivity of system frequency to control parameters is studied.Finally,the simulation results verify the effectiveness and practicability of the proposed control strategy. | Ming Sun Yong Min Xuejun Xiong Lei Chen Le Zhao Yuyao Feng Bingran Wang | 2022 | Journal of Modern Power Systems and Clean Energy2022，10，3： | 0 |
