| 1 | Future evolution of automated demand response system in smart grid for low-carbon economy显示文摘Smart grid construction is an important carrier and an effective way to promote the development of lowcarbon economy.Demand response(DR)is commonly regarded as an important core technology in smart grid field,and it reflects the flexible and interactive features of the core business in smart electricity.It is the developing direction of automated demand response(ADR)technology,and its main features are the standardization of information exchange,together with the intelligence of decision-making and the automation of implementations.ADR technology can improve the efficiency of the whole power system and enhance the ability to accept new energy sources.This paper analyzes the role of demand response in improving efficiency and low-carbon energy saving power systems.The automated demand response system architecture is investigated,and the ADR roadmap of commercial/industrial and residential customer is proposed.The key technologies for ADR system are analyzed,including demand response strategy,information exchanging model,measurement and verification techniques,and multi-agent scheduling techniques.To ensure the interoperability between the grid side and the user side,the ADR business in smart grid user interface standards is concluded to support further demand side management project. | Huaguang YAN Bin LI Songsong CHEN Ming ZHONG Dezhi LI Limin JIANG Guixiong HE | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，1： | 12 |
| 2 | Intensive phototherapy vs.exchange transfusion for the treatment of neonatal hyperbilirubinemia:a multicenter retrospective cohort study显示文摘Background:Intensive phototherapy(IPT)and exchange transfusion(ET)are the main treatments for extreme hyperbilirubinemia.However,there is no reliable evidence on determining the thresholds for these treatments.This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia.Methods:This retrospective cohort study was conducted in seven centers from January 2015 to January 2018.Patients with extreme hyperbilirubinemia that met the criteria of ET were included.Patients were divided into three subgroups(low-,medium-,and high-risk)according to gestational week and risk factors.Propensity score matching(PSM)was performed to balance the data before treatment.Study outcomes included the development of bilirubin encephalopathy,duration of hospitalization,expenses,and complications.Mortality,auditory complications,seizures,enamel dysplasia,ocular motility disorders,athetosis,motor,and language development were evaluated during follow-up at age of 3 years.Results:A total of 1164 patients were included in this study.After PSM,296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-,medium-,and high-risk subgroups with 188,364,and 40 matched patients,respectively.No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity,complications,and sequelae.Hospitalization duration and expenses were lower in the low-and medium-risk subgroups in the IPT only group.Conclusions:In this study,our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia.The indication of ET for patients with hyperbilirubinemia could be stricter.However,it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors.If IPT can be guaranteed and proved to be therapeutic,ET should be avoided as much as possible. | Meng Zhang Yang He Jun Tang Wenbin Dong Yong Zhang Benjin Zhang Hong Wan Quanmin Deng Lirong Guan Bin Xia Zhong Chen Min Ge Jing Zhao Wenxing Li Jingjun Pei Yi Qu Dezhi Mu | 2022 | Chinese Medical Journal2022，，5： | 7 |
| 3 | DNA tetrahedron-mediated immune-sandwich assay for rapid and sensitive detection of PSA through a microfluidic electrochemical detection system显示文摘Prostate-specific antigen(PSA)is the most widely used biomarker for the early diagnosis of prostate cancer.Existing methods for PSA detection are burdened with some limitations and require improvement.Herein,we developed a novel microfluidic–electrochemical(μFEC)detection system for PSA detection.First,we constructed an electrochemical biosensor based on screen-printed electrodes(SPEs)with modification of gold nanoflowers(Au NFs)and DNA tetrahedron structural probes(TSPs),which showed great detection performance.Second,we fabricated microfluidic chips by DNA TSP-Au NF-modified SPEs and a PDMS layer with designed dense meandering microchannels.Finally,theμFEC detection system was achieved based on microfluidic chips integrated with the liquid automatic conveying unit and electrochemical detection platform.TheμFEC system we developed acquired great detection performance for PSA detection in PBS solution.For PSA assays in spiked serum samples of theμFEC system,we obtained a linear dynamic range of 1–100 ng/mL with a limit of detection of 0.2 ng/mL and a total reaction time<25 min.Real serum samples of prostate cancer patients presented a strong correlation between the“gold-standard”chemiluminescence assays and theμFEC system.In terms of operation procedure,cost,and reaction time,our method was superior to the current methods for PSA detection and shows great potential for practical clinical application in the future. | Dezhi Feng Jing Su Yi Xu Guifang He Chenguang Wang Xiao Wang Tingrui Pan Xianting Ding Xianqiang Mi | 2021 | Microsystems & Nanoengineering2021，7，2： | 1 |

| 7 | Preparation and Characterization of Andalusite Ceramic Used for Solar Thermal Power Generation显示文摘High-temperature thermal storage material is one of the critical materials of solar thermal power generation system. Andalusite, kaolin, talc, γ-Al 2 O 3 and partially stabilized zirconia were used as the raw materials, and in-situ synthesis of cordierite was adopted to fabricate thermal storage material for solar thermal power generation via pressureless sintering. The phase compositions, microstructures and thermal shock resistances of the sintered samples were analyzed by XRD, SEM and EDS, and the corresponding mechanical properties were measured. The results show that the major phases of the samples are mullite and zirconium silicate, and the pores distribute uniformly. After being sintered at 1 460 ℃, A4 sample exhibits a better mechanical performance and thermal shock resistance, its loss rate of bending strength after 30 cycles thermal shock is 3.04%, the bulk density and bending strength are 2.86 g·cm-3 and 139.66 MPa, respectively. The better thermal shock resistance of the sample is closely related to the effect of zirconium silicate, such as its uniform distribution, nested growth with mullite, low thermal expansion coeffi cient, high thermal conductivity, etc. This ceramic can be widely used as one of potential thermal storage materials of solar thermal power generation system. | 吴建锋 CHENG Hao XU Xiaohong ZHOU Yang HE Dezhi LIU Yi | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，3： | 1 |
| 8 | Preparation and Characterization of Mullite-Silicon Carbide Heat Absorbing Ceramics for Solar Thermal Tower Plant显示文摘The in-situ synthesized mullite bonded SiC ceramics for solar thermal tower plant were prepared from Silicon carbide(SiC ), manufactured aluminum hydroxide(Al(OH)3) and Suzhou kaolin via semi-dry pressing and pressureless firing. The results indicate that sample B3(designed mullite content 15 wt%) fired at 1 400 ℃ exhibited optimal performance with a bending strength of 97.41 MPa. Sample B3 can withstand 30-cycles thermal shock without cracking(wind cooling from 1 100 ℃ to room temperature), and the bending strength after thermal shock decreased by 17.92%. When the service temperature is 600 °C, the thermal diffusivity, specific heat capacity, thermal conductivity and heat capacity are 6.48×10-2 cm2·s-1, 0.69 k J·kg-1· K-1, 9.62 W·m-1·K-1 and 977.76 k J·kg-1, respectively. The XRD and SEM results show that SiC , mullite, α-quartz, and tridymite are connected closely, which gives the material a good bending strength. After 30-time thermal shock cycles, the structure of samples becomes loose. SiC grains are intersectingly arranged with rodshape mullite, exhibiting a favorable thermal shock resistance. The addition of Al(OH)3 and Suzhou kaolin can accelerate the synthesis of mullite, thus to reduce the firing temperature effectively. The volume effect of tridymite is relatively small, improving the thermal shock resistance of materials. A higher designed mullite content yields a lower loss rate of bending strength. The mullite content should not be more than 15 wt% or else the bending strength would be diminished. | 徐晓虹 RAO Zhenggang WU Jianfeng ZHOU Yang HE Dezhi LIU Yi | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，1： | 1 |
| 9 | Simulation of positive streamer propagation in an air gap with a GFRP composite barrier显示文摘The puncture of glass fibre reinforced polymer(GFRP)laminate is a primary damage pattern of wind turbine blades due to lightning strikes.A numerical simulation model of positive streamer propagation in a needle‐to‐plate air gap with a GFRP laminate is established to investigate the breakdown mechanism of GFRP laminate.The model not only considers the dynamics of charged particles in the air and the composite laminate,but also the current continuity at gas-solid interfaces.The simulated streamer discharge pattern and the surface streamer length are in good agreement with the observation results.The distributions and evolutions of the electron number density,electric field,and surface charge densities during streamer propagation are obtained.It is found that the enhancement of the electric field on the GFRP laminate is caused by the rapid deposition of positive and negative space charges on the GFRP laminate after a secondary streamer incepts on the lower surface of the GFRP laminate.The effects of the applied voltage,relative permittivity,and thickness of the GFRP laminate on the electric field on the GFRP laminate are investigated.The obtained results could assist in further under-standing of the mechanism of GFRP wind blade breakdown due to lightning strikes. | Hengxin He Dezhi Xia Bin Luo Weijiang Chen Kai Bian NianWen Xiang | 2021 | High Voltage2021，6，6： | 1 |

| 13 | An efficient aggregation-enhanced delayed fluorescence luminogen created with spiro donors and carbonyl acceptor for applications as an emitter and sensitizer in high-performance organic light-emitting diodes显示文摘Organic light-emitting diodes(OLEDs)fabricated using organic thermally activated delayed fluorescence materials as sensitizers have recently achieved significant advancements,but the serious efficiency roll-offs are still troublesome in most cases.Herein,a tailor-made multifunctional luminogen SBF-BP-SFAC containing 9,9′-spirobifluorene(SBF)and spiro[acridine-9,9-fluorene](SFAC)as electron donors and carbonyl as an electron acceptor is synthesized and characterized.SBF-BPSFAC has the advantages of high thermal stability,aggregation-enhanced delayed fluorescence,and balanced carrier transport ability,and prefers horizontal dipole orientation.Highly efficient OLEDs employing SBF-BP-SFAC as an emitter radiate intense cyan light with outstanding external quantum efficiencies(ηexts)of up to 30.6%.SBF-BP-SFAC can also serve as an excellent sensitizer for orange fluorescence,phosphorescence,and delayed fluorescence materials,providing excellent η exts of up to 30.3% with very small efficiency roll-offs due to the fast Förster energy transfer as well as exciton annihilation suppression by bulky spiro donors.These outstanding performances demonstrate the great potential of SBF-BP-SFAC as an emitter and sensitizer for OLEDs. | Hao Chen Jiajie Zeng Ruishan Huang Jianghui Wang Junchu He Hao Liu Dezhi Yang Dongge Ma Zujin Zhao Ben Zhong Tang | 2023 | Aggregate2023，4，2： | 0 |
| 14 | Current Loop Disturbance Suppression for Dual Three Phase Permanent Magnet Synchronous Generators Based on Modified Linear Active Disturbance Rejection Control显示文摘A modified four-dimensional linear active disturbance rejection control(LADRC)strategy is proposed for a dual three-phase permanent magnet synchronous generator(DTP-PMSG)system to reduce cross-coupling between the d and q axis currents in the d-q subspace and harmonic currents in the x-y subspace.In the d-q subspace,the proposed strategy uses a model-based LADRC to enhance the decoupling effect between the d and q axes and the disturbance rejection ability against parameter variation.In the x-y subspace,the 5th and 7th harmonic current suppression abilities are improved by using quasi-resonant units parallel to the extended state observer of the traditional LADRC.The proposed modified LADRC strategy improved both the steady-state performance and dynamic response of the DTP-PMSG system.The experimental results demonstrate that the proposed strategy is both feasible and effective. | Dezhi Xu Hu Yao Yang He Wenxiang Zhao | 2024 | Chinese Journal of Electrical Engineering2024，10，1： | 0 |
| 15 | Rolling Bearing Fault Diagnosis Based On Convolutional Capsule Network显示文摘Fault diagnosis technology has been widely applied and is an important part of ensuring the safe operation of mechanical equipment.In response to the problem of frequent faults in rolling bearings,this paper designs a rolling bearing fault diagnosis method based on convolutional capsule network(CCN).More specifically,the original vibration signal is converted into a two-dimensional time–frequency image using continuous wavelet transform(CWT),and the feature extraction is performed on the two-dimensional time–frequency image using the convolution layer at the front end of the network,and the extracted features are input into the capsule network.The capsule network converts the extracted features into vector neurons,and the dynamic routing algorithm is used to achieve feature transfer and output the results of fault diagnosis.Two different datasets are used to compare with other traditional deep learning models to verify the fault diagnosis capability of the method.The results show that the CCN has good diagnostic capability under different working conditions,even in the presence of noise and insufficient samples,compared to other models.This method contributes to the safe and reliable operation of mechanical equipment and is suitable for other rotating scenarios. | Guangjun Jiang Dezhi Li Ke Feng Yongbo Li Jinde Zheng Qing Ni He Li | 2023 | Journal of Dynamics, Monitoring and Diagnostics2023，2，4： | 0 |
| 16 | In-situ construction of abundant active centers on hierarchically porous carbon electrode toward high-performance phosphate electrosorption: Synergistic effect of electric field and capture sites显示文摘Phosphate removal is crucial for eutrophication control and water quality improvement.Electro-assisted adsorption,an eco-friendly elec-trosorption process,exhibited a promising potential for wastewater treatment.However,there are few works focused on phosphate electro-sorption,and reported electrodes cannot attach satisfactory removal capacities and rates.Herein,electro-assisted adsorption of phosphate via in-situ construction of La active centers on hierarchically porous carbon(LaPC)has been originally demonstrated.The resulted LaPC composite not only possessed a hierarchically porous structure with uniformly dispersed La active sites,but also provided good conductivity for interfacial electron transfer.The LaPC electrode achieved an ultrahigh phosphate electrosorption capability of 462.01 mg g^(-1) at 1 V,outperforming most existing electrodes.The superior phosphate removal performance originates from abundant active centers formed by the coupling of electricfield and capture sites.Besides,the stability and selectivity toward phosphate capture were maintained well even under comprehensive conditions.Moreover,a series of kinetics and isotherms models were employed to validate the electrosorption process.This work demonstrates a deep understanding and promotes a new level of phosphate electrosorption. | Peng Zhang Fukuan Li Mingming He Silu Huo Xueli Zhang Benqiang Cen Dezhi Fang Kexun Li Hao Wang | 2024 | Green Energy & Environment2024，9，1： | 0 |
