| 1 | Kinematics and Dynamics Hessian Matrices of Manipulators Based on Screw Theory显示文摘The complexity of the kinematics and dynamics of a manipulator makes it necessary to simplify the modeling process.However,the traditional representations cannot achieve this because of the absence of coordinate invariance.Therefore,the coordinate invariant method is an important research issue.First,the rigid-body acceleration,the time derivative of the twist,is proved to be a screw,and its physical meaning is explained.Based on the twist and the rigid-body acceleration,the acceleration of the end-effector is expressed as a linear-bilinear form,and the kinematics Hessian matrix of the manipulator(represented by Lie bracket)is deduced.Further,Newton-Euler's equation is rewritten as a linear-bilinear form,from which the dynamics Hessian matrix of a rigid body is obtained.The formulae and the dynamics Hessian matrix are proved to be coordinate invariant.Referring to the principle of virtual work,the dynamics Hessian matrix of the parallel manipulator is gotten and the detailed dynamic model is derived.An index of dynamical coupling based on dynamics Hessian matrix is presented.In the end,a foldable parallel manipulator is taken as an example to validate the deduced kinematics and dynamics formulae.The screw theory based method can simplify the kinematics and dynamics of a manipulator,also the corresponding dynamics Hessian matrix can be used to evaluate the dynamical coupling of a manipulator. | ZHAO Tieshi GENG Mingchao CHEN Yuhang LI Erwei YANG Jiantao | 2015 | Chinese Journal of Mechanical Engineering2015，28，2： | 22 |
| 2 | The histone H3 lysine-27 demethylase Jmjd3 plays a critical role in specific regulation of Th17 cell differentiation显示文摘Interleukin(IL)17-producing T helper(Th17)cells play critical roles in the clearance of extracellular bacteria and fungi as well as the pathogenesis of various autoimmune diseases,such as multiple sclerosis,psoriasis,and ulcerative colitis.Although a global transcriptional regulatory network of Th17 cell differentiation has been mapped recently,the participation of epigenetic modifications in the differentiation process has yet to be elucidated.We demonstrated here that histone H3 lysine-27(H3K27)demethylation,predominantly mediated by the H3K27 demethylase Jmjd3,crucially regulated Th17 cell differentiation.Activation of naı¨ve CD41 T cells immediately induced high expression of Jmjd3.Genetic depletion of Jmjd3 in CD41 T cells specifically impaired Th17 cell differentiation both in vitro and in vivo.Ectopic expression of Jmjd3 largely rescued the impaired differentiation of Th17 cells in vitro in Jmjd3-deficientCD41 T cells.Importantly,Jmjd3-deficient mice were resistant to the induction of experimental autoimmune encephalomyelitis(EAE).Furthermore,inhibition of the H3K27 demethylase activity with the specific inhibitor GSK-J4 dramatically suppressed Th17 cell differentiation in vitro.At the molecular level,Jmjd3 directly bound to and reduced the level of H3K27 trimethylation(me3)at the genomic sites ofRorc,which encodes the masterTh17 transcription factorRorgt,and Th17 cytokine genes such as Il17,Il17f,and Il22.Therefore,our studies established acritical role of Jmjd3-mediatedH3K27demethylation inTh17 cell differentiation andsuggest that Jmjd3 can be a novel therapeutic target for suppressing autoimmune responses. | Zhi Liu Wei Cao Longxia Xu Xi Chen Yu Zhan Qian Yang Sanhong Liu Pengfei Chen Yuhang Jiang Xiaohua Sun Yu Tao Yiming Hu Cuifeng Li Qi Wang Ying Wang Charlie Degui Chen Yufang Shi Xiaoren Zhang | 2015 | Journal of Molecular Cell Biology2015，7，6： | 6 |
| 3 | Elevating H3K27me3 level sensitizes colorectal cancer to oxaliplatin显示文摘Histone methylation is a context-dependent modification that regulates gene expression,and the trimethylation of histone H3 lysine 27(H3K27me3)usually induces gene silencing.Overcoming colorectal cancer(CRC)chemoresistance is currently a huge challenge,but the relationship between H3K27me3 modification and chemoresistance remains largely unclear.Here,we found that H3K27me3 levels positively correlated with the metastasis-free survival of CRC patients and a low H3K27me3 level predicted a poor outcome upon chemotherapeutic drug treatment.Oxaliplatin stimulation significantly induced the expression of H3K27 lysine demethylase 6A/6B(KDM6A/6B),thus decreasing the level of H3K27me3 in CRC cells.Elevation of H3K27me3 level through KDM6A/6B depletion or GSK-J4(a KDM6A/6B inhibitor)treatment significantly enhanced oxaliplatin-induced apoptosis.Conversely,when inhibiting the expression of H3K27me3 by EPZ-6438,an inhibitor of the histone methyltransferase EZH2,the proportion of apoptotic cells remarkably decreased.In addition,the combination of GSK-J4 and oxaliplatin significantly inhibited tumor growth in an oxaliplatin-resistant patient-derived xenograft model.Importantly,we revealed that oxaliplatin treatment dramatically induced NOTCH2 expression,which was caused by downregulation of H3K27me3 level on the NOTCH2 transcription initiation site.Thus,the activated NOTCH signaling promoted the expression of stemness-related genes,which resulted in oxaliplatin resistance.Furthermore,oxaliplatin-induced NOTCH signaling could be interrupted by GSK-J4 treatment.Collectively,our findings suggest that elevating H3K27me3 level can improve drug sensitivity in CRC patients. | Qi Wang Xi Chen Yuhang Jiang Sanhong Liu Hanshao Liu Xiaohua Sun Haohao Zhang Zhi Liu Yu Tao Cuifeng Li Yiming Hu Dandan Liu Deji Ye Yongzhong Liu Mingliang Wang Xiaoren Zhang | 2020 | Journal of Molecular Cell Biology2020，12，2： | 6 |
| 4 | Parallel selection of distinct Tof5 alleles drove the adaptation of cultivated and wild soybean to high latitudes显示文摘Photoperiod responsiveness is a key factor limiting the geographic distribution of cultivated soybean and its wild ancestor.In particular,the genetic basis of the adaptation in wild soybean remains poorly understood.In this study,by combining whole-genome resequencing and genome-wide association studies we identified a novel locus,Time of Flowering 5(Tof5),which promotes flowering and enhances adaptation to high latitudes in both wild and cultivated soybean.By genomic,genetic and transgenic analyses we showed that Tof5 en-codes a homolog of Arabidopsis thaliana FRUITFULL(FUL).Importantly,further analyses suggested that different alleles of Tof5 have undergone parallel selection.The Tof5H1 allele was strongly selected by humans after the early domestication of cultivated soybean,while Tof5H2 allele was naturally selected in wild soybean,and in each case facilitating adaptation to high latitudes.Moreover,we found that the key flowering repressor E1 suppresses the transcription of Tof5 by binding to its promoter.In turn,Tof5 physically associates with the promoters of two important FLOWERING LOCUS T(FT),FT2a and FT5a,to upregulate their transcription and promote flowering under long photoperiods.Collectively,ourfindings provide insights into how wild soybean adapted to high latitudes through natural selection and indicate that cultivated soybean underwent changes in the same gene but evolved a distinct allele that was artificially selected after domestication. | Lidong Dong Qun Cheng Chao Fang Lingping Kong Hui Yang Zhihong Hou Yongli Li Haiyang Nan Yuhang Zhang Qingshan Chen Chunbao Zhang Kun Kou Tong Su Lingshuang Wang Shichen Li Haiyang Li Xiaoya Lin Yang Tang Xiaohui Zhao Sijia Lu Baohui Liu Fanjiang Kong | 2022 | Molecular Plant2022，15，2： | 5 |

| 8 | FT5a interferes with the Dt1-AP1 feedback loop to control flowering time and shoot determinacy in soybean显示文摘Flowering time and stem growth habit determine inflorescence architecture in soybean, which in turn influences seed yield. Dt1, a homolog of Arabidopsis TERMINAL FLOWER 1(TFL1), is a major controller of stem growth habit, but its underlying molecular mechanisms remain unclear.Here, we demonstrate that Dt1 affects node number and plant height, as well as flowering time,in soybean under long-day conditions. The b ZIP transcription factor FDc1 physically interacts with Dt1, and the FDc1-Dt1 complex directly represses the expression of APETALA1(AP1). We propose that FT5 a inhibits Dt1 activity via a competitive interaction with FDc1 and directly upregulates AP1. Moreover, AP1 represses Dt1 expression by directly binding to the Dt1 promoter, suggesting that AP1 and Dt1 form a suppressive regulatory feedback loop to determine the fate of the shoot apical meristem. These findings provide novel insights into the roles of Dt1 and FT5 a in controlling the stem growth habit and flowering time in soybean, which determine the adaptability and grain yield of this important crop. | Lin Yue Xiaoming Li Chao Fang Liyu Chen Hui Yang Jie Yang Zhonghui Chen Haiyang Nan Linnan Chen Yuhang Zhang Haiyang Li Xingliang Hou Zhicheng Dong James LWeller Jun Abe Baohui Liu Fanjiang Kong | 2021 | Journal of Integrative Plant Biology2021，63，6： | 3 |
| 9 | UV illumination enhanced desorption of oxygen molecules from monolayer MoS2 surface显示文摘The oxygen adsorption can drastically alter the electronic properties of the two-dimensional(2D)materials,which is usually dificult to be removed.In this work,we report the ultraviolet(UV)ilumination induced desorption of the O2 molecules from the monolayer MoS2 surface by using the atmosphere dependent transport measurement,Kelvin probe microscopy,photoluminescence spectroscopy and X-ray photoelectron spectroscopy.Obvious increasing of the conductivity,rising of the Fermi level,and red shift of the photoluminescence peaks of the MoS2 were observed after the UV ilumination in vacuum,indicating the elimination of the depletion effect from the oxygen adsorption.Such parameter changes can be reversibly recovered by the subsequent O2 exposure.Furthermore,obvious decreasing of the oxygen concentration after the UV ilumination was also observed by X-ray photoelectron spectroscopy.Thus the UV induced O2 photodesorption effect is evidenced.The photo-excited charge transfer mechanism is proposed to account for the photodesorption effect.These results provide a nondestructive way to clean the MoS2 surface and manipulate the performance of the MoS2 based devices. | Yuhang Wang Zhiquan He Jinbing Zhang Hao Liu Xubo Lai Boyang Liu Yibao Chen Fengping Wang Liuwan Zhang | 2020 | Nano Research2020，13，2： | 3 |
| 10 | Light-responsive and corrosion-resistant gas valve with non-thermal effective liquid-gating positional flow control显示文摘Safe and precise control of gas flow is one of the key factors to many physical and chemical processes,such as degassing,natural gas transportation,and gas sensor.In practical application,it is essential for the gas-involved physicochemical process to keep everything under control and safe,which significantly relies on the controllability,safety,and stability of their valves.Here we show a light-responsive and corrosion-resistant gas valve with non-thermal effective liquid-gating positional flow control under a constant pressure by incorporating dynamic gating liquid with light responsiveness of solid porous substrate.Our experimental and theoretical analysis reveal that the photoisomerization of azobenzene-based molecular photoswitches on the porous substrate enabled the gas valve to possess a light-responsive and reversible variation of substantial critical pressure of non-thermal effective gas flow switch.Moreover,the chemically inert gating liquid prevented the solid substrate from corrosion and,by combining with the high spatiotemporal resolution of light,the gas valve realizes a precisely positional open and close under a steady-state pressure.The application demonstrations in our results show the potentials of the new gas valve for bringing opportunities to many applications,such as gas-involved reaction control in microfluidics,soft actuators,and beyond. | Baiyi Chen Rongrong Zhang Yaqi Hou Jian Zhang Shiyan Chen Yuhang Han Xinyu Chen Xu Hou | 2021 | Light(Science & Applications)2021，10，7： | 3 |

| 12 | High-definition colorful perovskite narrowband photodetector array enabled by laser-direct-writing显示文摘Narrowband photodetectors as specific spectral sensing pixels have drawn intense attention in multispectral detection due to their distinct characteristic of filter-free spectrum discrimination,in which the emerging halide lead perovskites witness a booming development in their performance and wavelength-selectivity from blue to near-infrared light.However,the challenge in integrating perovskite narrowband photodetectors on one chip imposes an impediment on practical application.In this work,the combination of laser-direct-writing and ion exchange is proposed as an efficient way to fabricate high-definition colorful sensing array with perovskite narrowband photodetector unit as pixel.Under laser irradiation,the photolysis of halocarbon solvent(CHCl_(3),CH_(3)CH_(2)I,etc)releases the halide ions,which brings the ion exchange and gives rise to slow-varying bandgap in single perovskite photoactive film.This ion exchange can be controlled via laser irradiation time and focus point,thus enabling precisely engineerable bandgap.By optimizing the process,it is successfully applied to develop patterned perovskite narrow blue and green photodetectors array with a high-definition of~53 ppi.We believe this result will make a great step forward to integrate multifunctional perovskite devices on one chip,which will pave the way for perovskite optoelectronic device to the commercial application. | Xiaobao Xu Yuhang Dong Yuanzhou Zhang Zeyao Han Jiaxin Liu Dejian Yu Yi Wei Yousheng Zou Bo Huang Jun Chen Haibo Zeng | 2022 | Nano Research2022，15，6： | 2 |
| 13 | Improved Denoising Autoencoder for Maritime Image Denoising and Semantic Segmentation of USV显示文摘Unmanned surface vehicle(USV)is currently a hot research topic in maritime communication network(MCN),where denoising and semantic segmentation of maritime images taken by USV have been rarely studied.The former has recently researched on autoencoder model used for image denoising,but the existed models are too complicated to be suitable for real-time detection of USV.In this paper,we proposed a lightweight autoencoder combined with inception module for maritime image denoising in different noisy environments and explore the effect of different inception modules on the denoising performance.Furthermore,we completed the semantic segmentation task for maritime images taken by USV utilizing the pretrained U-Net model with tuning,and compared them with original U-Net model based on different backbone.Subsequently,we compared the semantic segmentation of noised and denoised maritime images respectively to explore the effect of image noise on semantic segmentation performance.Case studies are provided to prove the feasibility of our proposed denoising and segmentation method.Finally,a simple integrated communication system combining image denoising and segmentation for USV is shown. | Yuhang Qiu Yongcheng Yang Zhijian Lin Pingping Chen Yang Luo Wenqi Huang | 2020 | China Communications2020，17，3： | 2 |
| 14 | Analysis of molecular variation in porcine reproductive and respiratory syndrome virus in China between 2007 and 2012显示文摘In the present study, 89 porcine reproductive and respiratory syndrome virus(PRRSV) isolates in China during 2007 to 2012 were randomly selected from the GenBank genetic sequence database. Evolutionary characteristics of these isolates were analyzed based on the sequences of non-struc-tural protein 2(Nsp2) and glycoprotein 5(GP5). The genetic variations of the isolates were also compared with six representative strains. The results showed that a high degree of genetic diversity exists among the PRRSV population in China. Highly pathogenic PRRSV isolates, with a discon-tinuous deletion of a 30 amino acid residue in the Nsp2 region, remained the most dominant virus throughout 2007–2012 in China. Owing to the extensive use of representative vaccine strains, natu-ral recombination events occurred between strains. Three isolates – HH08, DY, and YN-2011 – were more closely related to vaccine strains than the other isolates. Both YN-2011 and DY were the evolu-tionary products of recombination events between strains SP and CH-1R. The results of the present study provide useful information for the epidemiology of PRRSV as well as for vaccine development. | Yuhang Cao Hongsheng Ouyang Mingjun Zhang Fuwang Chen Xin Yang Daxing Pang Linzhu Ren | 2014 | Virologica Sinica2014，29，3： | 2 |
| 15 | Single‑Atom Cobalt‑Based Electrochemical Biomimetic Uric Acid Sensor with Wide Linear Range and Ultralow Detection Limit显示文摘Uric acid(UA)detection is essential in diagnosis of arthritis,preeclampsia,renal disorder,and cardiovascular diseases,but it is very challenging to realize the required wide detection range and low detection limit.We present here a single-atom catalyst consisting of Co(Ⅱ)atoms coordinated by an average of 3.4 N atoms on an N-doped graphene matrix(A-Co-NG)to build an electrochemical biomimetic sensor for UA detection.The A-Co-NG sensor achieves a wide detection range over 0.4-41,950μM and an extremely low detection limit of 33.3±0.024 nM,which are much better than previously reported sensors based on various nanostructured materials.Besides,the A-Co-NG sensor also demonstrates its accurate serum diagnosis for UA for its practical application.Combination of experimental and theoretical calculation discovers that the catalytic process of the A-Co-NG toward UA starts from the oxidation of Co species to form a Co^3+-OH-UA*,followed by the generation of Co^3+-OH+^*UA_H,eventually leading to N-H bond dissociation for the formation of oxidized UA molecule and reduction of oxidized Co^3+to Co^2+for the regenerated A-Co-NG.This work provides a promising material to realize UA detection with wide detection range and low detection limit to meet the practical diagnosis requirements,and the proposed sensing mechanism sheds light on fundamental insights for guiding exploration of other biosensing processes. | Fang Xin Hu Tao Hu Shihong Chen Dongping Wang Qianghai Rao Yuhang Liu Fangyin Dai Chunxian Guo Hong Bin Yang Chang Ming Li | 2021 | Nano-Micro Letters2021，13，1： | 2 |
| 16 | Moisture-resistant,stretchable NO_(x)gas sensors based on laser-induced graphene for environmental monitoring and breath analysis显示文摘The accurate,continuous analysis of healthcare-relevant gases such as nitrogen oxides(NOx)in a humid environment remains elusive for low-cost,stretchable gas sensing devices.This study presents the design and demonstration of a moisture-resistant,stretchable NO_(x)gas sensor based on laser-induced graphene(LIG).Sandwiched between a soft elastomeric substrate and a moisture-resistant semipermeable encapsulant,the LIG sensing and electrode layer is first optimized by tuning laser processing parameters such as power,image density,and defocus distance.The gas sensor,using a needlelike LIG prepared with optimal laser processing parameters,exhibits a large response of 4.18%o ppm^(-1)to NO and 6.66%o ppm^(-1)to NO_(2),an ultralow detection limit of 8.3 ppb to NO and 4.0 ppb to NO_(2),fast response/recovery,and excellent selectivity.The design of a stretchable serpentine structure in the LIG electrode and strain isolation from the stiff island allows the gas sensor to be stretched by 30%.Combined with a moisture-resistant property against a relative humidity of 90%,the reported gas sensor has further been demonstrated to monitor the personal local environment during dfferent times of the day and analyze human breath samples to classify patients with respiratory diseases from healthy volunteers.Moisture-resistant,stretchable NO_(x)gas sensors can expand the capability of wearable devices to detect biomarkers from humans and exposed environments for early disease diagnostics. | Li Yang Guanghao Zheng Yaoqian Cao Chuizhou Meng Yuhang Li Huadong Ji Xue Chen Guangyu Niu Jiayi Yan Ye Xue Huanyu Cheng | 2022 | Microsystems & Nanoengineering2022，8，4： | 2 |
| 17 | Trace Amounts of Triple-Functional Additives Enable Reversible Aqueous Zinc-Ion Batteries from a Comprehensive Perspective显示文摘Although their cost-effectiveness and intrinsic safety,aqueous zinc-ion batteries suffer from notorious side reactions including hydrogen evolution reaction,Zn corrosion and passivation,and Zn dendrite formation on the anode.Despite numerous strategies to alleviate these side reactions have been demonstrated,they can only provide limited performance improvement from a single aspect.Herein,a triple-functional additive with trace amounts,ammonium hydroxide,was demonstrated to comprehensively protect zinc anodes.The results show that the shift of electrolyte pH from 4.1 to 5.2 lowers the HER potential and encourages the in situ formation of a uniform ZHS-based solid electrolyte interphase on Zn anodes.Moreover,cationic NH^(4+)can preferentially adsorb on the Zn anode surface to shield the“tip effect”and homogenize the electric field.Benefitting from this comprehensive protection,dendrite-free Zn deposition and highly reversible Zn plating/stripping behaviors were realized.Besides,improved electrochemical performances can also be achieved in Zn//MnO_(2)full cells by taking the advantages of this triple-functional additive.This work provides a new strategy for stabilizing Zn anodes from a comprehensive perspective. | Ruwei Chen Wei Zhang Quanbo Huang Chaohong Guan Wei Zong Yuhang Dai Zijuan Du Zhenyu Zhang Jianwei Li Fei Guo Xuan Gao Haobo Dong Jiexin Zhu Xiaohui Wang Guanjie He | 2023 | Nano-Micro Letters2023，15，6： | 2 |
| 18 | Large extracellular vesicles secreted by human iPSC-derived MSCs ameliorate tendinopathy via regulating macrophage heterogeneity显示文摘Tendinopathy is a common musculoskeletal disorder which results in chronic pain and reduced performance.The therapeutic effect of stem cell derived-small extracellular vesicles(sEVs)for tendinopathy has been validated in recent years.However,whether large extracellular vesicles(lEVs),another subset of extracellular vesicles,possesses the ability for the improvement of tendinopathy remains unknown.Here,we showed that lEVs secreted from iPSC-derived MSCs(iMSC-lEVs)significantly mitigated pain derived from tendinopathy in rats.Immuno-histochemical analysis showed that iMSC-lEVs regulated the heterogeneity of infiltrated macrophages and several inflammatory cytokines in rat tendon tissue.Meanwhile,in vitro experiments revealed that the M1 pro-inflammatory macrophages were repolarized towards M2 anti-inflammatory macrophages by iMSC-lEVs,and this effect was mediated by regulating p38 MAPK pathway.Moreover,liquid chromatography-tandem mass spectrometry analysis identified 2208 proteins encapsulated in iMSC-lEVs,including 134 new-found proteins beyond current Vesiclepedia database.By bioinformatics and Western blot analyses,we showed that DUSP2 and DUSP3,the negative regulator of p38 phosphorylation,were enriched in iMSC-lEVs and could be transported to macrophages.Further,the immunomodulatory effect of iMSC-lEVs on macrophages was validated in explant tendon tissue from tendinopathy patients.Taken together,our results demonstrate that iMSC-lEVs could reduce inflammation in tendinopathy by regulating macrophage heterogeneity,which is mediated via the p38 MAPK pathway by delivery of DUSP2 and DUSP3,and might be a promising candidate for tendinopathy therapy. | Teng Ye Zhengsheng Chen Jieyuan Zhang Lei Luo Renzhi Gao Liangzhi Gong Yuhang Du Zongping Xie Bizeng Zhao Qing Li Yang Wang | 2023 | Bioactive Materials2023，，3： | 2 |
| 19 | Enhanced thermoelectric performance of two dimensional MS2(M=Mo,W)through phase engineering显示文摘The potential application of monolayer MS2(M?Mo,W)as thermoelectric material has been widely studied since the first report of successful fabrication.However,their performances are hindered by the considerable band gap and the large lattice thermal conductivity in the pristine 2H phase.Recent discoveries of polymorphism in MS2s provide new opportunities for materials engineering.In this work,phonon and electron transport properties of both 2H and 1T0 phases were investigated by first-principle calculations.It is found that upon the phase transition from 2H to 1T0 in MS2,the electron transport is greatly enhanced,while the lattice thermal conductivity is reduced by several times.These features lead to a significant enhancement of power factor by one order of magnitude in MoS2 and by three times in WS2.Meanwhile,the figure of merit can reach up to 0.33 for 1T0eMoS2 and 0.68 for 1T0eWS2 at low temperature.These findings indicate that monolayer MS2 in the 1T0 phase can be promising materials for thermoelectric devices application.Meanwhile,this work demonstrates that phase engineering techniques can bring in one important control parameter in materials design. | Bin Ouyang Shunda Chen Yuhang Jing Tianran Wei Shiyun Xiong Davide Donadio | 2018 | Journal of Materiomics2018，4，4： | 2 |
| 20 | Advances in inorganic nanoparticles trapping stiffness measurement:A promising tool for energy and environmental study显示文摘Optical tweezers system has emerged as an efficient tool to manipulate tiny particles in a non-invasive way.Trapping stiffness,as an essential parameter of an optical potential well,represents the trapping stability.Additionally,trapping inorganic nanoparticles such as metallic nanoparticles or other functionalized inorganic nanoparticles is important due to their properties of good stability,high conductivity,tolerable toxicity,etc.,which makes it an ideal detection strategy for bio-sensing,force calculation,and determination of particle and environmental properties.However,the trapping stiffness measurement(TSM)methods of inorganic nanoparticles have rarely been analyzed and summarized.Here,in this review,the principle and methods of TSM are analyzed.We also systematically summarize the progress in acquiring inorganic particles trapping stiffness and its promising applications.In addition,we provide prospects of the energy and environment applications of optical tweezering technique and TSM.Finally,the challenges and future directions of achieving the nanoparticles trapping stiffness are discussed. | Xiaolin Chen Jiajie Chen Jianxing Zhou Xiaoqi Dai Yuhang Peng Yili Zhong Ho-Pui Ho Bruce Zhi Gao Han Zhang Junle Qu Yonghong Shao | 2023 | Energy Reviews2023，2，2： | 1 |
