| 1 | Defined tumor antigen-specific T cells potentiate personalized TCR-T cell therapy and prediction of immunotherapy response显示文摘Personalized immunotherapy targeting tumor-specific antigens(TSAs)could generate efficient and safe antitumor immune response without damaging normal tissues.Although neoantigen vaccines have shown therapeutic effect in clinic trials,precise prediction of neoantigens from tumor mutations is still challenging.The host antitumor immune response selects and activates T cells recognizing tumor antigens.Hence,T cells engineered with T-cell receptors(TCRs)from these naturally occurring tumor antigen-specific T(Tas)cells in a patient will target personal TSAs in his/her tumor.To establish such a personalized TCR-T cell therapy,we comprehensively characterized T cells in tumor and its adjacent tissues by single-cell mRNA sequencing(scRNA-seq),TCR sequencing(TCR-seq)and in vitro neoantigen stimulation.Compared to bystander T cells circulating among tissues,Tas cells were characterized by tumor enrichment,tumor-specific clonal expansion and neoantigen specificity.We found that CXCL13 is a unique marker for both CD4^(+)and CD8^(+)Tas cells.Importantly,TCR-T cells expressing TCRs from Tas cells showed significant therapeutic effects on autologous patient-derived xenograft(PDX)tumors.Intratumoral Tas cell levels measured by CXCL13 expression precisely predicted the response to immune checkpoint blockade,indicating a critical role of Tas cells in the antitumor immunity.We further identified CD200 and ENTPD1 as surface markers for CD4^(^(+))and CD8^(^(+))Tas cells respectively,which enabled the isolation of Tas cells from tumor by Fluorescence Activating Cell Sorter(FACS)sorting.Overall,our results suggest that TCR-T cells engineered with Tas TCRs are a promising agent for personalized immunotherapy,and intratumoral Tas cell levels determine the response to immunotherapy. | Jingjing He Xinxin Xiong Han Yang Dandan Li Xuefei Liu Shuo Li Shuangye Liao Siyu Chen Xizhi Wen Kuai Yu Lingyi Fu Xingjun Dong Kaiyu Zhu Xiaojun Xia Tiebang Kang Chaochao Bian Xiang Li Haiping Liu Peirong Ding Xiaoshi Zhang Zhenjiang Liu Wende Li Zhixiang Zuo Penghui Zhou | 2022 | Cell Research2022，32，6： | 10 |
| 2 | Recent progress of nanogenerators acting as biomedical sensors in vivo显示文摘Since the nanogenerator(NG) was invented in 2006, it has been successfully developed and utilized to harvest various forms of mechanical energy in vivo. The NGs promote the progress of self-powered biomedical devices. Moreover, NGs can also be used as sensors to detect a variety of important physiological signals, which brings us closer to real-time, high-fidelity monitoring of physical and pathological information. This paper summarizes the in vivo applications of NGs as biomedical sensors, including in cardiac sensors, respiration sensors, blood pressure sensors, gastrointestinal sensors and bladder sensors.However, there are still many challenges in using NGs as sensors in vivo. For example, how can we minimize and encapsulate the NGs, how can we increase the stability and reliability during long-term detection, and how can we establish a corresponding relationship between the NG’s electrical output and the physiological signals. It is also critical to follow the medical principles more closely in the development of self-powered sensors in the future. We believe that the self-powered sensors would promote the development of the next-generation healthcare monitoring systems. | Jinyan Sun Anping Yang Chaochao Zhao Fang Liu Zhou Li | 2019 | Science Bulletin2019，64，18： | 9 |
| 3 | A wearable noncontact free-rotating hybrid nanogenerator for self-powered electronics显示文摘Self-powerability is a new trend in the development of portable devices.Harvesting biomechanical energy to power personal information electronics is of great significance.In this work,we report a wearable noncontact freerotating hybrid nanogenerator(WRG),which is constituted by a triboelectric nanogenerator and an electromagnetic generator.A continuous output over 2 seconds can be achieved during one instantaneous incentive by external force,which is improved by two orders of magnitude compared to other wearable nanogenerators due to its unique mechanical energy storage design.The WRG can be integrated into shoes to generate an output energy of 14.68 mJ in each stepping,which meets the power requirements of most personal information electronics.The wireless sensor,GPS,and smartphone can be powered by the WRG continuously.The WRG is expected to be applied in self-powered information electronics extensively in the future. | Dongjie Jiang Han Ouyang Bojing Shi Yang Zou Puchuan Tan Xuecheng Qu Shengyu Chao Yuan Xi Chaochao Zhao Yubo Fan Zhou Li | 2020 | InfoMat2020，2，6： | 8 |

The database of acupuncture and moxibustion prescriptions for AD was established by using Excel software so as to conduct the descriptive analysis, association analysis on the data.RESULTS: Baihui(GV 20), Sishencong(EX-HN 1),Shenmen(HT 7), Zusanli(ST 36), Neiguan(PC 6),Fengchi(GB 20), Taixi(KI 3), Dazhui(GV 14), Shenshu(BL 23), Sanyinjiao(SP 6), Shenting(GV 24), Fenglong(ST 40), Xuanzhong(GB 39), Shuigou(GV 26)and Taichong(LR 3) were of higher frequency in the treatment of AD with acupnucture and moxibustion. Most acupoints were selected from the Governor Vessel. The commonly used acupoints were located on the head, face, neck and lower limbs. The combination of the local acupoints with the distal ones was predominated. The crossing points among the specific points presented the advantage in the treatment. The association analysis indicated that the correlation among Fengchi(GB 20)-Baihui(GV 20) was the strongest, followed by combinations of Dazhui(GV 14)-Baihui(GV 20), Shenshu(BL 23)-Baihui(GV 20) and Neiguan(PC 6)-Baihui(GV 20) and indicated the common rules of the clinical acupoint selection and combination for AD.CONCLUSION: Our findings provide a reference for acupoints selection and combination for AD in clinical acupuncture practice. | Yu Chaochao Wang Li Kong Lihong Shen Feng Ma Chaoyang Du Yanjun Zhou Hua | 2018 | Journal of Traditional Chinese Medicine2018，38，6： | 4 |
| 5 | Volcanoes and Climate:Sizing up the Impact of the Recent Hunga Tonga-Hunga Ha'apai Volcanic Eruption from a Historical Perspective显示文摘An undersea volcano at Hunga Tonga-Hunga Ha'apai(HTHH)near the South Pacific island nation of Tonga,erupted violently on 15 January 2022.Potential climate impact of the HTHH volcanic eruption is of great concern to the public;here,we intend to size up the impact of the HTHH eruption from a historical perspective.The influence of historical volcanic eruptions on the global climate are firstly reviewed,which are thought to have contributed to decreased surface temperature,increased stratospheric temperature,suppressed global water cycle,weakened monsoon circulation and El Niño-like sea surface temperature.Our understanding of the impacts of past volcanic eruptions on global-scale climate provides potential implication to evaluate the impact of the HTHH eruption.Based on historical simulations,we estimate that the current HTHH eruption with an intensity of 0.4 Tg SO_(2)injection will decrease the global mean surface temperature by only 0.004℃in the first year after eruption,which is within the amplitude of internal variability at the interannual time scale and thus not strong enough to have significant impacts on the global climate. | Meng ZUO Tianjun ZHOU Wenmin MAN Xiaolong CHEN Jian LIU Fei LIU Chaochao GAO | 2022 | Advances in Atmospheric Sciences2022，39，12： | 4 |
| 6 | Atomically precise metal-chalcogenide semiconductor molecular nanoclusters with high dispersibility:Designed synthesis and intracluster photocarrier dynamics显示文摘A comprehensive understanding of excited-state dynamics of semiconductor quantum dots or nanomaterials at the atomic or molecular level is of scientific importance.Pure inorganic(or non-covalently protected)seimiconductor molecular nanoclusters with atomically precise structure are contributive to establish accurate correlation of excited-state dynamics with their composition/structure,however,the related studies are almost blank because of unresolved solvent dispersion issue.Herein,we designedly created the largest discrete chalcogenide seimiconductor molecular nanoclusters(denoted P2-CuMSnS,M=In or/and Ga)with great dispersibility,and revealed an interesting intracluster“core–shell”charge transfer relaxation dynamics.A systematic red shift in absorption spectra with the gradual substitution of In by Ga was experimentally and computationally investigated,and femtosecond transient absorption measurements further manifested there were three ultrafast processes in excited-state dynamics of P2 nanoclusters with the corresponding amplitudes directed by composition variation.Current results hold the great promise of the solution-processible applications of semiconductor-NC-based quantum dots and facilitate the development of atomically precise nano-chemistry. | Jiaxu Zhang Chaochao Qin Yeshuang Zhong Xiang Wang Wei Wang Dandan Hu Xiaoshuang Liu Chaozhuang Xue Rui Zhou Lei Shen Yinglin Song Dingguo Xu Zhien Lin Jun Guo Haifeng Su Dong-Sheng Li Tao Wu | 2020 | Nano Research2020，13，10： | 2 |

| 8 | Highly Aligned Ultra-Thick Gel-Based Cathodes Unlocking Ultra-High Energy Density Batteries显示文摘Increasing electrode thickness can substantially enhance the specific energy of lithium-ion batteries;however,ionic transport,electronic conductivity,and ink rheology are current barriers to adoption.Here,a novel approach using a mixed xanthan gum and locust bean gum binder to construct ultrathick electrodes is proposed to address above issues.After combining aqueous binder with single-walled carbon nanotubes(SWCNT),active material(LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)) and subsequent vacuum freeze-drying,highly aligned,and low-tortuosity structures with a porosity of ca.50%can be achieved with an average pore size of 10μm,whereby the gum binder-SWCNT-NMC811 forms vertical structures supported by tissue-like binder/SWCNT networks allowing for excellent electronic conducting phase percolation.As a result,ultra-thick electrodes with a mass loading of about 511 mg cm^(−2) and 99.5 wt%active materials have been demonstrated with a remarkable areal capacity of 79.3 mAh cm^(−2),which is the highest value reported so far.This represents a>25×improvement compared with conventional electrodes with an areal capacity of about 3 mAh cm^(−2).This route also can be expanded to other electrode materials,such as LiFePO_(4) and Li_(4)Ti_(5)O_(12),and thus opens the possibility for low-cost and sustainable ultra-thick electrodes with increased specific energy for future lithium-ion batteries. | Shichun Yang Chaochao Zhou Qiong Wang Binbin Chen Yan Zhao Bin Guo Zhengjie Zhang Xinlei Gao Ridwanur Chowdhury Huizhi Wang Chao Lai Nigel P.Brandon Billy Wu Xinhua Liu | 2022 | Energy & Environmental Materials2022，5，4： | 0 |
| 9 | Morphological,electromagnetic and absorbing properties of GR/Fe_(93.5)Si_(3.5)La_(1)Ce_(2) composite powders显示文摘In this study,the morphological,electromagnetic and absorbing properties of GR/Fe_(93.5)Si_(3.5)La_(1)Ce_(2) composite powders were systematically investigated.The composite powders was prepared by highenergy ball milling.X-ray diffractometer(XRD) and Raman spectroscopy analyses confirm the presence of α-Fe and graphene in the composite powders.Scanning electron microscopy(SEM) observation shows that the composite powders have a flake morphology.The electromagnetic and absorbing properties of the composite powders were analyzed with a vector network analyzer.When the milling time and graphene content are 12 h and 1 wt%,respectively,the composite powders exhibit the best absorbing property.For 1.0 wt% GR/Fe_(93.5)Si_(3.5)La_(1)Ce_(2) composite at 0.3 GHz,the ε’and ε' are 77.76 and124.73,and the μ’and μ' are 6.09 and 2.83.Its tanδ_(ε),tanδ_(μ) and tanδ reach 0.63,13.80 and 14.43,respectively,which basically increased the tanδ by more than 2 times compared with other composite powders.This indicates that the composite powder has excellent wave absorption performance.Meanwhile,the analysis shows that the loss mechanism of the composite powder is mainly relaxation loss,conduction loss,eddy current loss and natural resonance.Therefore,this composite powder provides a new approach for the development of wave absorbing materials. | Wei Zhou Chaochao Zeng Zhenghou Zhu | 2023 | Journal of Rare Earths2023，41，1： | 0 |
| 10 | FinB rain 2.0:when finance meets trustworthy AI显示文摘Artificial intelligence(AI) has accelerated the advancement of financial services by identifying hidden patterns from data to improve the quality of financial decisions. However, in addition to commonly desired attributes,such as model accuracy, financial services demand trustworthy AI with properties that have not been adequately realized. These properties of trustworthy AI are interpretability, fairness and inclusiveness, robustness and security,and privacy protection. Here, we review the recent progress and limitations of applying AI to various areas of financial services, including risk management, fraud detection, wealth management, personalized services, and regulatory technology. Based on these progress and limitations, we introduce FinBrain 2.0, a research framework toward trustworthy AI. We argue that we are still a long way from having a truly trustworthy AI in financial services and call for the communities of AI and financial industry to join in this effort. | Jun ZHOU Chaochao CHEN Longfei LI Zhiqiang ZHANG Xiaolin ZHENG | 2022 | Frontiers of Information Technology & Electronic Engineering2022，23，12： | 0 |
| 11 | Photosensitivity sources of dissolved organic matter from wastewater treatment plants and their mediation effect on 17α-ethinylestradiol photodegradation显示文摘Dissolved organic matter(DOM)from each treatment process of wastewater treatment plants(WWTPs)contains abundant photosensitive substances,which could significantly affect the photodegradation of 17α-ethinylestradiol(EE2).Nevertheless,information about EE2 photodegradation behavior mediated by DOM from diverse WWTPs and the photosensitivity sources of such DOM are inadequate.This study explored the photodegradation behavior of EE2 mediated by four typical WWTPs’DOM solutions and investigated the photosensitivity sources of DOM in the anaerobic-anoxic-oxic(A2/O)process.The parallel factor analysis identified three varying fluorescing components of these DOM,tryptophan-like substances or protein-like substances,microbial humuslike substances,and humic-like components.The photodegradation rate constants of EE2 were positively associated with the humification degree of DOM(P<0.05).The triplet state substances were responsible for the degradation of EE2.DOM extracted from the A2/O process,especially in the secondary treatment process had the fastest EE2 photodegradation rate compared to that of the other three processes.Four types of components(water-soluble organic matter(WSOM),extracellular polymeric substance,humic acid,and fulvic acid)were separated from the A2/O process DOM.WSOM had the highest promotion effect on EE2 photodegradation.Fulvic acid-like components and humic acid-like organic compounds in WSOM were speculated to be important photosensitivity substances that can generate triplet state substances.This research explored the physicochemical properties and photosensitive sources of DOM in WWTPs,and explained the fate of estrogens photodegradation in natural waters. | Zhicheng Liao Bei Li Juhong Zhan Huan He Xiaoxia Yang Dongxu Zhou Guoxi Yu Chaochao Lai Bin Huan Xuejun Pan | 2023 | Frontiers of Environmental Science & Engineering2023，17，6： | 0 |

| 13 | Tuning coherent phonon dynamics in two-dimensional phenylethylammonium lead bromide perovskites显示文摘Organic-inorganic layered perovskites are two-dimensional quantum well layers in which the layers of lead halide octahedra are stacked between the organic cation layers.The packing geometry of the soft organic molecules and the stiff ionic crystals induce structural deformation of the inorganic octahedra,generating complex lattice dynamics.Especially,the dielectric confinement and ionic sublattice lead to strong coupling between the photogenerated excitons and the phonons from the polar lattice which intensively affects the properties for device applications.The anharmonicity and dynamic disorder from the organic cations participate in the relaxation dynamics coupled with excitations.However,a detailed understanding of this underlying mechanism remains obscure.This work investigates the electron–optical phonon coupling dynamics by employing ultrafast pump-probe transient absorption spectroscopy.The activated different optical phonon modes are observed via systematic studies of(PEA)_(2)PbBr_(4) perovskite films on the ultrafast lattice vibrational dynamics.The experimental results indicate that solvent engineering has a significant influence on lattice vibrational modes and coherent phonon dynamics.This work provides fresh insights into electron-optical phonon coupling for emergent optoelectronics development based on layered perovskites. | Minghuan Cui Chaochao Qin Zhongpo Zhou Yuanzhi Jiang Shichen Zhang Zeye Yuan Mingjian Yuan Kun Yu Yuhai Jiang Yufang Liu | 2023 | Nano Research2023，16，2： | 0 |
| 14 | Lignin-based electrospun nanofiber membrane decorated with photo-Fenton Ag@MIF-100(Fe) heterojunctions for complex wastewater remediation显示文摘Membrane technology for wastewater remediation has aroused wide interest owing to its unique properties and potential applications.However,it remains challenging to explore green,efficient and robust membrane material and technique for complex wastewater treatment.Herein,we proposed using a simple electrospinning and in situ seeding method to fabricate a lignin-based electrospun nanofiber membrane(LENM)decorated with photo-Fenton Ag@MIL-100(Fe)heterojunctions for efficient separation of oil/water emulsions and degradation of organic dye.Thanks to the embedded lignin in LENM,an ultrahigh MIL-100(Fe)loading(53 wt%)with good wettability and high porosity was obtained.As a result,the hybrid Ag@MIL-100(Fe)/LENM exhibited excellent oil/water emulsions separation efficiency(more than 97%)without a compromise of water flux.Moreover,the hybrid membrane showed an excellent dye removal with degradation of 99%methylene blue within 30 min under illumination,which is attributed to a synergy of dye adsorption/enrichment and photo-Fenton catalytic degradation from Ag@MIL-100(Fe).Therefore,the lignin-based photo-Fenton hybrid membrane can lay the foundation for the preparation and application of green,sustainable and versatile membrane materials and technologies for efficient complex wastewater remediation. | Guodong Tian Chao Duan Bingxu Zhou Chaochao Tian Qiang Wang Jiachuan Chen | 2023 | Frontiers of Chemical Science and Engineering2023，17，7： | 0 |
