| 3 | A novel phenoxazine-based hole transport material for efficient perovskite solar cell显示文摘Based on the previous research work in our laboratory, we have designed and synthesized a small-molecule,hole transport material(HTM) POZ6-2 using phenoxazine(POZ) as central unit and dicyanovinyl units as electron-withdrawing terminal groups. Through the introduction of a 2-ethyl-hexyl bulky chain into the POZ core unit, POZ6-2 exhibits good solubility in organic solvents. In addition, POZ6-2 possesses appropriate energy levels in combination with a high hole mobility and conductivity in its pristine form. Therefore, it can readily be used as a dopant-free HTM in perovskite solar cells(PSCs) and a conversion efficiency of 10.3% was obtained. The conductivity of the POZ6-2 layer can be markedly enhanced via doping in combination with typical additives, such as 4-tert-butylpyridine(TBP) and lithium bis(trifluoromethanesulfonyl) imide(Li TFSI).Correspondingly, the efficiency of the PSCs was further improved to 12.3% using doping strategies. Under the same conditions, reference devices based on the well-known HTM Spiro-OMe TAD show an efficiency of 12.8%. | Ming Cheng Cheng Chen Bo Xu Yong Hua Fuguo Zhang Lars Kloo Licheng Sun | 2015 | Journal of Energy Chemistry2015，24，6： | 1 |
| 4 | Single-cell transcriptomic atlas of goat ovarian aging显示文摘Background The ovaries are one of the first organs that undergo degenerative changes earlier in the aging process,and ovarian aging is shown by a decrease in the number and quality of oocytes.However,little is known about the molecular mechanisms of female age-related fertility decline in different types of ovarian cells during aging,especially in goats.Therefore,the aim of this study was to reveal the mechanisms driving ovarian aging in goats at single-cell resolution.Results For the first time,we surveyed the single-cell transcriptomic landscape of over 27,000 ovarian cells from newborn,young and aging goats,and identified nine ovarian cell types with distinct gene-expression signatures.Functional enrichment analysis showed that ovarian cell types were involved in their own unique biological processes,such as Wnt beta-catenin signalling was enriched in germ cells,whereas ovarian steroidogenesis was enriched in granulosa cells(GCs).Further analysis showed that ovarian aging was linked to GCs-specific changes in the antioxidant system,oxidative phosphorylation,and apoptosis.Subsequently,we identified a series of dynamic genes,such as AMH,CRABP2,THBS1 and TIMP1,which determined the fate of GCs.Additionally,FOXO1,SOX4,and HIF1A were identified as significant regulons that instructed the differentiation of GCs in a distinct manner during ovarian aging.Conclusions This study revealed a comprehensive aging-associated transcriptomic atlas characterizing the cell typespecific mechanisms during ovarian aging at the single-cell level and offers new diagnostic biomarkers and potential therapeutic targets for age-related goat ovarian diseases. | Dejun Xu Shuaifei Song Fuguo Wang Yawen Li Ziyuan Li Hui Yao Yongju Zhao Zhongquan Zhao | 2024 | Journal of Animal Science and Biotechnology2024，15，1： | 0 |
| 5 | A crosslinked polymer as dopant-free hole-transport material for efficient n-i-p type perovskite solar cells显示文摘A new crosslinked polymer,called P65,with appropriate photo-electrochemical,opto-electronic,and thermal properties,has been designed and synthesized as an efficient,dopant-free,hole-transport material(HTM)for n-i-p type planar perovskite solar cells(PSCs).P65 is obtained from a low-cost and easily synthesized spiro[fluorene-9,90-xanthene]-30,60-diol(SFX-OH)-based monomer X65 through a freeradical polymerization reaction.The combination of a three-dimensional(3 D)SFX core unit,holetransport methoxydiphenylamine group,and crosslinked polyvinyl network provides P65 with good solubility and excellent film-forming properties.By employing P65 as a dopant-free hole-transport layer in conventional n-i-p type PSCs,a power conversion efficiency(PCE)of up to 17.7%is achieved.To the best of our knowledge,this is the first time a 3 D,crosslinked,polymeric dopant-free HTM has been reported for use in conventional n-i-p type PSCs.This study provides a new strategy for the future development of a 3 D crosslinked polymeric dopant-free HTM with a simple synthetic route and low-cost for commercial,large-scale applications in future PSCs. | Linqin Wang Fuguo Zhang Tianqi Liu Wei Zhang Yuanyuan Li Bin Cai Lanlan He Yu Guo Xichuan Yang Bo Xu James M.Gardner Lars Kloo Licheng Sun | 2021 | Journal of Energy Chemistry2021，30，4： | 0 |
| 6 | Special issue on on-board optimization strategy design methods for connected hybrid electric vehicles显示文摘As a trend in the innovation of automotive engineering,connectivity provides new opportunities and challenging issues for vehicular powertrain control due to big potential in the use of the connected information for improving energy efficiency and reducing CO_(2) emission.In real world driving situation,a bottleneck for achieving optimal energy efficiency via control of the power sources in the powertrain is the uncertainty in power demand,since the power demand is delivered by the driver according to the driving environment which is always with stochasticity and un-detectable event in the environment.The connectivity enables us to predict the power demand in advance by using the real-time information of vehicle-to-vehicle,vehicle-to-infrastructure. | Tielong Shen Carlos Guardiola Fuguo Xu | 2022 | Control Theory and Technology2022，20，2： | 0 |
| 7 | On-board torque management approach to the E-COSM benchmark problem with a prediction-based engine assignment显示文摘This paper proposes an energy management strategy for the benchmark problem of E-COSM 2021 to improve the energy efficiency of hybrid electric vehicles(HEVs)on a road with a slope.We assume that HEVs are in a connected environment with real-time vehicle-to-everything information,including geographic information,vehicle-to-infrastructure information and vehicle-to-vehicle information.The benchmark problem to be solved is based on HEV powertrain control using traffic information to achieve fuel economy improvements while satisfying the constraints of driving safety and travel time.The proposed strategy includes multiple rules and model predictive control(MPC).The rules of this strategy are designed based on external environment information to maintain safe driving and to determine the driving mode.To improve fuel economy,the optimal energy management strategy is primarily considered,and to perform real-time energy management via RHC-based optimization in a connected environment with safety constraints,a key issue is to predict the dynamics of the preceding vehicle during the targeted horizon.Therefore,this paper presents a real-time model-based optimization strategy with learning-based prediction of the vehicle’s future speed.To validate the proposed optimization strategy,a powertrain control simulation platform in a traffic-in-the-loop environment is constructed,and case study results performed on the constructed platform are reported and discussed. | Bo Zhang Jiangyan Zhang Fuguo Xu | 2022 | Control Theory and Technology2022，20，2： | 0 |
| 8 | Real-time optimization of energy consumption under adaptive cruise control for connected HEVs显示文摘This paper presents a real-time energy optimization algorithm for a hybrid electric vehicle(HEV)that operates with adaptive cruise control(ACC).Real-time energy optimization is an essential ssue such that the HEV powertrain system is as efficient as possible.With connected vehice technique,ACC system shows considerable potential of high energy eficiency.Combining a classical ACC algorithm,a two-level cooperative control scheme is constructed to realize real-time power distribution for the host HEV that operates in a vehicle platoon.The proposed control strategy actually provides a solution for an optimal control problem with multi objectives in terms of string stable of vehicle platoon and energy consumption minimization of the individual following vehicle.The string stability and the real-time optimization performance of the cooperative control system are confirmed by simulations with respect to several operating scenarios. | Jiangyan ZHANG Fuguo XU | 2020 | Control Theory and Technology2020，18，2： | 0 |

| 10 | Advances in chemokines of teleost fish species显示文摘In mammals,chemokines are a superfamily of cytokines that regulate cell migration or exert direct antimicrobial activity.The presence and organization of four invariant cysteine residues within the mature protein sequence can classify chemokines into four major subfamilies:CXC,CC,CX_(3)C,and XC.In teleost,a novel subfamily of chemokines named CX has been identified.Since the first report of a CC chemokine(CK1)in rainbow trout in 1998,the number of identified chemokine genes in different fish species has expanded dramatically.In this paper,we reviewed the chemokine genes that have been identified so far in teleost fish and their tissue expressions and responses post-stimulation.We also discussed the functions of fish chemokines based on currently available information and compared them to human chemokines.Additionally,we predicted the structures of trout chemokines for the first time,and we found that the structures of trout chemokines share significant similarities.Finally,the adjuvant effects of fish chemokines in aquaculture were also reviewed.Overall,this review will give us a better understanding of the chemokines of teleost fish. | Hongsen Xu Fuguo Liu | 2024 | Aquaculture and Fisheries2024，9，2： | 0 |
| 11 | Gear downshift control of inverse-automatic mechanical transmission of electric vehicle显示文摘In order to improve the driving dynamics and riding comfort of pure electric vehicles,taking a two-speed I-AMT(Inverse-Automatic Mechanical Transmission)with rear friction clutch as the research object,a gear shift strategy,which consists of the open-loop control of the clutch position control and the closed-loop control of the drive motor speed control,is proposed.Considering the inherent time-delay and external disturbances within the motor speed adjustment system,a two DOF(degree-of-freedom)Smith predictor with feedforward input is designed to track the target speed of the drive motor.The feedforward input is used to eliminate the influence of clutch sliding friction on the motor speed control,while the feedback speed tracking controller is applied to realize the speed tracking performance with the existence of time-delay and the external disturbance.In order to verify the effectiveness of the gear shift control strategy and the accuracy of the two DOF Smith controller with feedforward control,simulation results comparison is firstly carried out to illustrate the effectiveness of the control scheme.Then,a light pure electric vehicle equipped with I-AMT was used for downshift experiments under large throttle,which is the most difficult working scenario to control the transmission.The experimental results show that the two DOF Smith controller can eliminate the influence of time-delay on the closed-loop control,and the proposed whole gear shift control strategy can limit the clutch slippage time within 1.5 s,resulting in a smaller shift jerk,thus guarantee the driving dynamics and riding comfort simultaneously. | Jinlong Hong Chao Zhang Hankun Chu Bingzhao Gao Hao Wu Guangjie Wei Hua Liu Fuguo Xu | 2022 | Green Energy and Intelligent Transportation2022，1，1： | 0 |
