| 2 | Energy-saving Superconducting Magnetic Energy Storage(SMES)Based Interline DC Dynamic Voltage Restorer显示文摘The fast-response feature from a superconducting magnetic energy storage(SMES)device is favored for suppressing instantaneous voltage and power fluctuations,but the SMES coil is much more expensive than a conventional battery energy storage device.In order to improve the energy utilization rate and reduce the energy storage cost under multiple-line power distribution conditions,this paper investigates a new interline DC dynamic voltage restorer(IDC-DVR)scheme with one SMES coil shared among multiple compensating circuits.In this new concept,an improved current-voltage(I/V)chopper assembly,which has a series of input/output power ports,is introduced to connect the single SMES coil with multiple power lines,and thereby satisfy the independent energy exchange requirements of any line to be compensated.Specifically,if two or more power lines have simultaneous compensating demands,the SMES coil can be selectively controlled to compensate the preferable line according to the priority order of the line.The feasibility of the proposed scheme is technically verified to maintain the transient voltage stability in multiple-line voltage swell and sag cases caused by either output voltage fluctuations from external power sources or power demand fluctuations from local sensitive loads.The simulation results provide a technical basis to develop a cost-effective SMES-based IDC-DVR for use in various DC distribution networks. | Xiaoyuan Chen Qi Xie Xingming Bian Boyang Shen | 2022 | CSEE Journal of Power and Energy Systems2022，8，1： | 4 |
| 3 | Structured hierarchical Mn–Co mixed oxides supported on silicalite-1 foam catalyst for catalytic combustion显示文摘Silicalite-1(S1)foam was functionalized by supporting manganese-cobalt(Mn-Co)mixed oxides to develop the structured hierarchical catalyst(Mn-Co@SlF)for catalytic combustion for the first time.The self-supporting S1 foam with hierarchical porosity was prepared via hydrothermal synthesis with polyurethane(PU)foam as the template.Subsequently,Mn-Co oxide nano sheets were uniformly grown on the surface of S1 foams under hydrothermal conditions to prepare the structured hierarchical catalyst with specific surface area of 354 m^2·g^-1,micropore volume of 0.141 cm^3·g^-1 and total pore volume of 0.217 cm3·g^-1,as well as a good capacity to adsorb toluene(1.7 mmol·g^-1 at p/p0=0.99).Comparative catalytic combustion of toluene of over developed structured catalyst Mn-Co@SlF was performed against the control catalysts of bulk Mn-Co@S1(i.e.,the crushed Mn-Co@SlF)and unsupported Mn-Co oxides(i.e.,Mn-Co).Mn-Co@SlF exhibited comparatively the best catalytic performance,that is,complete and stable toluene conversion at 2480 C over 65 h due to the synergy between Mn-Co oxides and S1 foam,which provided a large number of oxygen vacancies,high redox capacity.In addition,the hierarchical porous structure also improved the accessibility of active sites and facilitated the global mass transfer across the catalyst bed,being beneficial to the catalysis and catalyst longevity. | Yanan Guan Hengyu Shen Xing Guo Boyang Mao Zhenyuan Yang Yangtao Zhou He Liang Xiaolei Fan Yilai Jiao jinsong Zhang | 2020 | Chinese Journal of Chemical Engineering2020，28，9： | 3 |
| 4 | Optimising the electroluminescence performance of ZnS:Cu/epoxy composites via exploring the relationship between electroluminescence intensity and filler intrinsic attributes显示文摘Electroluminescent composites have considerable potential for applications in photoelectric display,electric field measurement and other fields due to their advantages of simple preparation and uniform luminescence.However,high voltage required by the operation of electroluminescent composites hinders their applications in the electric domain,and research on the relationship between electroluminescence principle of composites and filler intrinsic attributes is insufficient.In this paper,the effects of electric field strength,filler mass fraction and voltage frequency on the electroluminescence intensity of ZnS:Cu/epoxy composites are studied,which are majorly used as the luminescent layer of electroluminescent devices.To enhance the electroluminescence intensity of composites,high-temperature sintered BaTiO_(3)and zinc oxide whiskers(ZnOw)particles are introduced in the base matrix.The finite element method is applied to verify that the matrix of high dielectric constant is in favour of improving the electroluminescence intensity of composites.The band structure of the ZnS:Cu particle is calculated based on the density functional theory+U method to analyse the intrinsic relationship between electroluminescence and particle electronic structure.This paper provides a basis for the research of high electroluminescence intensity devices and will be conducive to better understanding on the relationship between electroluminescence principle and filler intrinsic attributes. | Wen Qi Miao Liu Siqi Chen Kun He Luxing Zhao Boyang Shen Xingming Bian | 2022 | High Voltage2022，7，6： | 2 |

| 6 | Synergistic Promotion of Electrical, Mechanical and Thermal Properties for Silicone Rubber-based Field Grading Material via Compound Modification显示文摘Use of nonlinearconductive SiC/silicone rubber(SR)field grading material(FGM)can improve the local field concentration of composite insulators.Adding large volume fraction and large-size SiC particles(SiCp)into SR can obtain a good field grading effect,but it is accompanied by the deterioration of mechanical properties.Compounding SiC with different shapes can solve this contradiction.By incorporating one-dimensional SiC whiskers(SiCw)to synergize with granular SiCp,SiC/SR FGM with better field-dependent conductivity,mechanical properties and thermal conductivity than large-size SiCp and large volume fraction filling case can be obtained by using smaller size SiCp and lower filling contents.The simulations of 500 kv line insulators show that the modified SiC/SR FGM can reduce the maximum field strength along the insulator surface and at sheath-core rod interfaces by 55%and 71.4%,respectively.The combined application of FGM and grading ring can achieve a complementary effect.Using FGM to partially replace the role of the grading rings,the field strength indicators can still meet the operational requirements after the tube radius and shielding depth of the grading rings at both ends are reduced by 36.2%and 40%separately,which is a benefit to alleviating the problems of high weight and large volume faced by traditional field grading methods. | Jiale Wu Yangzhi Gong Peiqi Xiong Zexi Xing Xiaofeng Xue Xiao Yang Boyang Shen Xingming Bian | 2024 | CSEE Journal of Power and Energy Systems2024，10，1： | 0 |
| 7 | Effect of TiO_(2)coating on the surface condition and corona characteristics of positive DC conductors with particle matters显示文摘Persistent severe smog and dust weather exists in many regions of China.Particles accu-mulate on the surface of high‐voltage transmission lines,which affects the surface morphology of the transmission line and induces corona discharge.This work mainly studies the influence of electric field and photocatalysis on the corona characteristics of transmission lines.In this work,plasma spraying is used to prepare a dense,smooth and excellent photocatalytic TiO_(2)coating on the surface of transmission wires.An electron microscope and a white light interference profilometer is used to study the surface condition of the samples.The variation in the surface condition of the samples is observed under different fouling,light time and electric field intensity.The corona characteristics of power transmission lines under different surface conditions are studied.The results show that light and applied electric field promote the photocatalytic effect of TiO_(2),which helps to decompose the contamination on the surface of power transmission wires and thus reduce the corona discharge of transmission lines.The increase in corona inception voltage reduces the corona current pulse repetition rate and the ion current density during corona discharge. | Pei Xu Yanxiang Ma Jie Zhu Luxing Zhao Boyang Shen Xingming Bian | 2022 | High Voltage2022，7，1： | 0 |
| 8 | Experiments and Analysis of Corona Inception Voltage Under Combined AC-DC Voltages at Various Air Pressure and Humidity in Rod to Plane Electrodes显示文摘As the effect of climate plays a significant role in corona discharge under combined voltages,the variation of corona inception voltage with different air pressure and humidities is studied.An experimental platform,based on a rod-to-plane electrode,is constructed with adjustable air pressure from 0.06 MPa to 0.10 MPa and with a relative humidity(RH)from 20%to 90%.The variation of ultraviolet(UV)photon count and corona inception voltage is obtained at various climate conditions under different applied voltages:the single AC,single DC,and combined AC-DC.It turns out that all the corona inception voltages decline with the drop of air pressure and the rise of humidity under different applied voltages.The influence between different voltages primarily relies on space charge,as more AC components make it easier to accumulate positive ions.The existence of AC makes ions move forward and backward while the existence of DC dominates the polarity of corona and general drift directions.At last the fitting formula of hybrid corona inception voltage combining air pressure and relative humidity is given. | Zichen He Junyu Zhu Jie Zhu Xingming Bian Boyang Shen | 2021 | CSEE Journal of Power and Energy Systems2021，7，4： | 0 |
| 9 | Superconducting fault current limiter(SFCL)for fail-safe DC-DC conversion:From power electronic device to micro grid protection显示文摘In DC micro grids and networks,DC-DC power converters having a large number of semiconductor-based power electronic devices are usually adopted to interconnect the renewable sources and flexible loads.Most of the semiconductor-based devices suffer from poor fault withstanding abilities,but conventional power electronic protection schemes have the bottlenecks of the time-delay,self-malfunction and mis-judgement.This paper presents a novel solution using the superconducting fault current limiter(SFCL)to protect a power electronic device and extend the usage to a micro grid.This SFCL is actually a self-triggering,recoverable,and passive current limiter,which does not involve any additional circuit hardware and software.Experimental investigations and simulation analyses clarify the feasibility of using this superconductor-based protection scheme to implement the self-acting fail-safe protection of DC-DC converters.Further system-level simulations explore the SFCL to suppress the over-current and stabilize the bus voltage of a photovoltaic based DC micro grid,particularly facing millisecond-level transients and faults.Our experimental and theoretical investigations lay some technical bases to establish a superconductor-semiconductor-coupled interdisciplinary application from the view from the applied superconductivity,to power electronics,and to micro grids. | Xiaoyuan Chen Mingshun Zhang Yu Chen Shan Jiang Huayu Gou Yi Lei Boyang Shen | 2022 | Superconductivity2022，，1： | 0 |
| 10 | METTL14 is a chromatin regulator independent of its RNA N^(6)-methyladenosine methyltransferase activity显示文摘METTL3 and METTL14 are two components that form the core heterodimer of the main RNA m^(6)A methyltransferase complex(MTC)that installs m^(6)A.Surprisingly,depletion of METTL3 or METTL14 displayed distinct effects on stemness maintenance of mouse embryonic stem cell(mESC).While comparable global hypo-methylation in RNA m^(6)A was observed in Mettl3 or Mettl14 knockout mESCs,respectively.Mettl14 knockout led to a globally decreased nascent RNA synthesis,whereas Mettl3 depletion resulted in transcription upregulation,suggesting that METTL14 might possess an mA-independent role in gene regulation.We found that METTL14 colocalizes with the repressive H3K27me3 modification.Mechanistically,METTL14,but not METTL3,binds H3K27me3 and recruits KDM6B to induce H3K27me3 demethylation independent of METTL3.Depletion of METTL14 thus led to a global increase in H3K27me3 level along with a global gene suppression.The effects of METTL14 on regulation of H3K27me3 is essential for the transition from self-renewal to differentiation of mESCs.This work reveals a regulatory mechanism on heterochromatin by METTL14 in a manner distinct from METTL3 and independently of m^(6)A,and critically impacts transcriptional regulation,stemness maintenance,and differentiation ofmESCs. | Xiaoyang Dou Lulu Huang Yu Xiao Chang Liu Yini Li Xinning Zhang Lishan Yu Ran Zhao Lei Yang Chuan Chen Xianbin Yu Boyang Gao Meijie Qi Yawei Gao Bin Shen Shuying Sun Chuan He Jun Liu | 2023 | Protein & Cell2023，14，9： | 0 |
| 11 | Isolation and microbial transformation of tea sapogenin from seed pomace of Camellia oleifera with anti-inflammatory effects显示文摘In the current study,tea saponin,identified as the primary bioactive constituent in seed pomace of Camellia oleifera Abel.,was meticulously extracted and hydrolyzed to yield five known sapogenins:16-O-tiglogycamelliagnin B(a),camelliagnin A(b),16-O-angeloybarringtogenol C(c),theasapogenol E(d),theasapogenol F(e).Subsequent biotransformation of compound a facilitated the isolation of six novel metabolites(a1−a6).The anti-inflammatory potential of these compounds was assessed using pathogenassociated molecular patterns(PAMPs)and damage-associated molecular patterns molecules(DAMPs)-mediated cellular inflammation models.Notably,compounds b and a2 demonstrated significant inhibitory effects on both lipopolysaccharide(LPS)and high-mobility group box 1(HMGB1)-induced inflammation,surpassing the efficacy of the standard anti-inflammatory agent,carbenoxolone.Conversely,compounds d,a3,and a6 selectivity targeted endogenous HMGB1-induced inflammation,showcasing a pronounced specificity.These results underscore the therapeutic promise of C.oleifera seed pomace-derived compounds as potent agents for the management of inflammatory diseases triggered by infections and tissue damage. | SHEN Pingping JIANG Xuewa ZHANG Jingling WANG Jiayi Raj Richa LI Guolong GE Haixia WANG Weiwei YU Boyang ZHANG Jian | 2024 | Chinese Journal of Natural Medicines2024，22，3： | 0 |
