| 1 | Pathological changes in the lungs and lymphatic organs of 12 COVID-19 autopsy cases显示文摘Systematic autopsy and comprehensive pathological analyses of COVID-19 decedents should provide insights into the disease characteristics and facilitate the development of novel therapeutics.In this study,we report the autopsy findings from the lungs and lymphatic organs of 12 COVID-19 decedents—findings that evaluated histopathological changes;immune cell signature and inflammatory factor expression in the lungs,spleen and lymph nodes.Here we show that the major pulmonary alterations included diffuse alveolar damage,interstitial fibrosis and exudative inflammation featured with extensive serous and fibrin exudates,macrophage infiltration and abundant production of inflammatory factors(IL-6,IP-10,TNFo?and IL-I f).The spleen and hilar lymph nodes contained lesions with tissue structure disruption and immune cell dysregulation,including lymphopenia and macrophage accumulation.These findings provide pathological evidence that links injuries of the lungs and lymphatic organs with the fatal systematic respiratory and immune malfunction in critically ill COVID-19 patients. | Qian Liu Yu Shi Jun Cai Yaqi Duan Rongshuai Wang Hongyan Zhang Qiurong Ruan Jiansha Li Lei Zhao Yifang Ping Rong Chen Liang Ren Xiaochun Fei Heng Zhang Rui Tang Xi Wang Tao Luo Xindong Liu Xuequan Huang Zhenhua Liu Qilin Ao Yong Ren Jing Xiong Zhicheng He Haibo Wu Wenjuan Fu Pengnan Zhao Xinwei Chen Guoqiang Qu Yunyun Wang Xi Wang Jia Liu Dongfang Xiang Sanpeng Xu Xiaowei Zhou Qingrui Li Jinghong Ma Heng Li Jie Zhang Sizhe Huang Xiaohong Yao Yiwu Zhou Chaofu Wang Dingyu Zhang Guoping Wang Liang Liu Xiu-Wu Bian | 2020 | National Science Review2020，7，12： | 6 |
| 2 | A four-gene signature-derived risk score for glioblastoma:prospects for prognostic and response predictive analyses显示文摘Objective: Glioblastoma(GBM) is the most common primary malignant brain tumor regulated by numerous genes, with poor survival outcomes and unsatisfactory response to therapy.Therefore, a robust, multi-gene signature-derived model is required to predict the prognosis and treatment response in GBM.Methods: Gene expression data of GBM from TCGA and GEO datasets were used to identify differentially expressed genes(DEGs)through DESeq2 or LIMMA methods.The DEGs were then overlapped and used for survival analysis by univariate and multivariate COX regression.Based on the gene signature of multiple survival-associated DEGs, a risk score model was established,and its prognostic and predictive role was estimated through Kaplan–Meier analysis and log-rank test.Gene set enrichment analysis(GSEA) was conducted to explore high-risk score-associated pathways.Western blot was used for protein detection.Results: Four survival-associated DEGs of GBM were identified: OSMR, HOXC10, SCARA3, and SLC39A10.The four-gene signature-derived risk score was higher in GBM than in normal brain tissues.GBM patients with a high-risk score had poor survival outcomes.The high-risk group treated with temozolomide chemotherapy or radiotherapy survived for a shorter duration than the low-risk group.GSEA showed that the high-risk score was enriched with pathways such as vasculature development and cell adhesion.Western blot confirmed that the proteins of these four genes were differentially expressed in GBM cells.Conclusions: The four-gene signature-derived risk score functions well in predicting the prognosis and treatment response in GBM and will be useful for guiding therapeutic strategies for GBM patients. | Mianfu Cao Juan Cai Ye Yuan Yu Shi Hong Wu Qing Liu Yueliang Yao Lu Chen Weiqi Dang XiangZhang Jingfang Xiao Kaidi Yang Zhicheng He Xiaohong Yao Yonghong Cui Xia Zhang Xiuwu Bian | 2019 | Cancer Biology & Medicine2019，16，3： | 2 |
| 3 | Silk-based hydrogel incorporated with metal-organic framework nanozymes for enhanced osteochondral regeneration显示文摘Osteochondral defects(OCD)cannot be efficiently repaired due to the unique physical architecture and the pathological microenvironment including enhanced oxidative stress and inflammation.Conventional strategies,such as the control of implant microstructure or the introduction of growth factors,have limited functions failing to manage these complex environments.Here we developed a multifunctional silk-based hydrogel incorporated with metal-organic framework nanozymes(CuTA@SF)to provide a suitable microenvironment for enhanced OCD regeneration.The incorporation of CuTA nanozymes endowed the SF hydrogel with a uniform microstructure and elevated hydrophilicity.In vitro cultivation of mesenchymal stem cells(MSCs)and chondrocytes showed that CuTA@SF hydrogel accelerated cell proliferation and enhanced cell viability,as well as had antioxidant and antibacterial properties.Under the inflammatory environment with the stimulation of IL-1β,CuTA@SF hydrogel still possessed the potential to promote MSC osteogenesis and deposition of cartilage-specific extracellular matrix(ECM).The proteomics analysis further confirmed that CuTA@SF hydrogel promoted cell proliferation and ECM synthesis.In the full-thickness OCD model of rabbit,CuTA@SF hydrogel displayed successfully in situ OCD regeneration,as evidenced by micro-CT,histology(HE,S/O,and toluidine blue staining)and immunohistochemistry(Col I and aggrecan immunostaining).Therefore,CuTA@SF hydrogel is a promising biomaterial targeted at the regeneration of OCD. | Zhicheng Cao Hongmei Wang Jialin Chen Yanan Zhang Qingyun Mo Po Zhang Mingyue Wang Haoyang Liu Xueyang Bao Yuzhi Sun Wei Zhang Qingqiang Yao | 2023 | Bioactive Materials2023，，2： | 2 |

| 5 | Halogenated Thermally Activated Delayed Fluorescence Materials for Efficient Scintillation显示文摘Organic scintillators,materials with the ability to exhibit luminescence when exposed to X-rays,have aroused increasing interest in recent years.However,the enhancement of radioluminescence and improving X-ray absorption of organic scintillators lie in the inherent dilemma,due to the waste of triplet excitons and weak X-ray absorption during scintillation.Here,we employ halogenated thermally activated delayed fluorescence materials to improve the triplet exciton utilization and X-ray absorption simultaneously,generating efficient scintillation with a low detection limit,which is one order of magnitude lower than the dosage for X-ray medical diagnostics.Through experimental study and theoretical calculation,we reveal the positive role of X-ray absorption,quantum yields of prompt fluorescence,and intersystem crossing in promoting the radioluminescence intensity.This finding offers an opportunity to design diverse types of organic scintillators and expands the applications of thermally activated delayed fluorescence. | Xiao Wang Guowei Niu Zixing Zhou Zhicheng Song Ke Qin Xiaokang Yao Zhijian Yang Xiaoze Wang He Wang Zhuang Liu Chengzhu Yin Huili Ma Kang Shen Huifang Shi Jun Yin Qiushui Chen Zhongfu An Wei Huang | 2023 | Research2023，，4： | 1 |
| 6 | Ore-forming age and tectonic setting of the Linjiasandaogou gold deposit in the Liaodong Peninsula,northeast China:constraints from geochronology and geochemistry显示文摘The Linjiasandaogou gold deposit is located in the Qingchengzi Orefield,North China Craton,China,and has not attracted many studies.We present geochronological,whole-rock geochemical,and Sr–Nd–Hf isotopic data to constrain the age and tectonic setting of the mineralization.U–Pb dating of zircon from pre-and post-ore dikes indicates the Linjiasandaogou Au deposit formed at ca.227–226 Ma.The granite porphyry(ca.227 Ma)and quartz diorite porphyry(ca.228 Ma),which are slightly older than the mineralization,have(;Sr/;Sr)i-=0.7127–0.7162,εNd(t)=–13.7 to–17.0,andεHf(t)=–14.6 to–16.9,and display enrichment in light rare earth elements and large ion lithophile elements and depletion in high field strength elements.Two lamprophyres(226 and225 Ma),which are slightly younger than the mineralization,have higher(;Sr/;Sr)i(0.7165–0.7216),negativeεNd(t)(–11.2 to–14.3)andεHf(t)(–15.6 to–18.6)values,and are enriched in light rare earth elements but depleted in high field strength elements(Nb and Ta).The geochemical characteristics of the granitoid and lamprophyres indicate a lower crustal and enriched mantle source,respectively.We infer that the Linjiasandaogou Au deposit formed in a postcollisional tectonic setting,following the collision between the North China,Yangtze craton,and Central Asian Orogeny in Triassic. | Xiaofeng Yao Tingjie Yan Zhicheng Lü Chenggui Lin Kuifeng Mi Shenghui Li Yang Li Wange Du | 2022 | Acta Geochimica2022，41，2： | 1 |
| 7 | Tyramine-enhanced zwitterion hyaluronan hydrogel coating for anti-fouling and anti-thrombosis显示文摘Zwitterions have aroused much interest to endow implantable medical devices with anti-fouling and anti-thrombosis performance,due to their ability to form a hydrated layer that can provide a good barrier against protein and cell adhesion. Herein,tyramine modified sulfobetaine-derived sodium hyaluronan(HST) hydrogel coating was fabricated, in which hyaluronan(HA)was used as polysaccharide skeleton to graft zwitterionic sulfobetaine, and tyramine was introduced as crosslinker to construct both the network of hydrogel and a strong covalent bond between coating and substrate. Hydrogel coating was prepared by spin coating or painting HST prepolymer solution under ultraviolet light irradiation. The obtained HST hydrogel coating shows good stability. Moreover, in addition to its outstanding anti-fouling performance and good biocompatibility, it can effectively prevent thrombosis in blood circulation ex vivo. This work offers a universal strategy to prepare a high-performance anti-fouling and antithrombosis coating, which is expected to promote the development of functional coatings for biomedical materials. | GUO ZhiCheng YAO MengMeng SUN Hong SHI MingYue DONG XiaoRu HE ShaoShuai GUO BingYan YAO FangLian ZHANG Hong LI JunJie | 2022 | Science China(Technological Sciences)2022，65，8： | 1 |
| 8 | Science with the 2.5-meter Wide Field Survey Telescope(WFST)显示文摘The Wide Field Survey Telescope(WFST) is a dedicated photometric surveying facility being built jointly by University of Science and Technology of China(USTC) and the Purple Mountain Observatory(PMO). It is equipped with a 2.5-meter diameter primary mirror, an active optics system, and a mosaic CCD camera with 0.73 gigapixels on the primary focal plane for highquality image capture over a 6.5-square-degree field of view. The installation of WFST near the summit of Saishiteng mountain in the Lenghu region is scheduled in summer of 2023, and the operation is planned to start three months later. WFST will scan the northern sky in four optical bands(u, g, r and i) at cadences from hourly/daily in the deep high-cadence survey(DHS) program, to semi-weekly in the wide field survey(WFS) program. During a photometric night, a nominal 30 s exposure in the WFS program will reach a depth of 22.27, 23.32, 22.84, and 22.31(AB magnitudes) in these four bands, respectively, allowing for the detection of a tremendous amount of transients in the low-z universe and a systematic investigation of the variability of Galactic and extragalactic objects. In the DHS program, intranight 90 s exposures as deep as 23(u) and 24 mag(g), in combination with target of opportunity follow-ups, will provide a unique opportunity to explore energetic transients in demand for high sensitivities, including the electromagnetic counterparts of gravitational wave events, supernovae within a few hours of their explosions,tidal disruption events and fast, luminous optical transients even beyond redshift of unity. In addition, the final 6-year co-added images, anticipated to reach g■25.8 mag in WFS or 1.5 mags deeper in DHS, will be of fundamental importance to general Galactic and extragalactic science. The highly uniform legacy surveys of WFST will serve as an indispensable complement to those of the Vera C. Rubin Observatory's Legacy Survey of Space and Time(LSST) that monitors the southern sky. | Tinggui Wang Guilin Liu Zhenyi Cai Jinjun Geng Min Fang Haoning He Ji-an Jiang Ning Jiang Xu Kong Bin Li Ye Li Wentao Luo Zhizheng Pan Xuefeng Wu Ji Yang Jiming Yu Xianzhong Zheng Qingfeng Zhu Yi-Fu Cai Yuanyuan Chen Zhiwei Chen Zigao Dai Lulu Fan Yizhong Fan Wenjuan Fang Zhicheng He Lei Hu Maokai Hu Zhiping Jin Zhibo Jiang Guoliang Li Fan Li Xuzhi Li Runduo Liang Zheyu Lin Qingzhong Liu Wenhao Liu Zhengyan Liu Wei Liu Yao Liu Zheng Lou Han Qu Zhenfeng Sheng Jianchun Shi Yiping Shu Zhenbo Su Tianrui Sun Hongchi Wang Huiyuan Wang Jian Wang Junxian Wang Daming Wei Junjie Wei Yongquan Xue Jingzhi Yan Chao Yang Ye Yuan Yefei Yuan Hongxin Zhang Miaomiao Zhang Haibin Zhao Wen Zhao | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，10： | 1 |

| 10 | Partition-Based Cache Replacement to Manage Shared L2 Caches显示文摘The Least recently used(LRU) replacement has been widely employed by on-chip shared caches. With the increase of cache associativity, the performance gap between LRU and theoretical optimal replacement algorithm is significant, motivating us to design alternative replacement algorithms to improve cache performance. We propose a Partition-based cache replacement(PCR) algorithm to manage multi-core shared L2 caches. PCR takes into consideration recency and frequency information of cache access, and cache resource interference among multiple competing applications. PCR is effective to filter out the less frequently reused blocks through a dynamic insertion/promotion policy based on the target partitions, and ensures that some fraction of the working set is retained in the cache to contribute to more hits. Our evaluation shows that PCR improves performance of an 8-core system by an average of 11.3% over LRU-based cache. | FANG Juan WANG Jing LI Chengyan YAO Zhicheng KE Weimao | 2014 | Chinese Journal of Electronics2014，23，3： | 1 |
| 11 | Advancements in understanding mechanisms of hepatocellular carcinoma radiosensitivity:A comprehensive review显示文摘Primary liver cancer is a significant health problem worldwide.Hepatocellular carcinoma(HCC)is the main pathological type of primary liver cancer,accounting for 75%-85%of cases.In recent years,radiotherapy has become an emerging treatment for HCC and is effective for various stages of HCC.However,radiosensitivity of liver cancer cells has a significant effect on the efficacy of radiotherapy and is regulated by various factors.How to increase radiosensitivity and improve the therapeutic effects of radiotherapy require further exploration.This review summarizes the recent research progress on the mechanisms affecting sensitivity to radiotherapy,including epigenetics,transportation and metabolism,regulated cell death pathways,the microenvironment,and redox status,as well as the effect of nanoparticles on the radiosensitivity of liver cancer.It is expected to provide more effective strategies and methods for clinical treatment of liver cancer by radiotherapy. | Gaoyuan Yang Huamei Yan Yongchang Tang Feng Yuan Mingbo Cao Yupeng Ren Yuxuan Li Zhiwei He Xiaorui Su Zhicheng Yao Meihai Deng | 2023 | Chinese Journal of Cancer Research2023，35，3： | 1 |
| 12 | The capacity and mechanisms of various oxidants on regulating the redox function of ZVI显示文摘It is well known that zero-valent iron(ZVI)could catalyze the oxidation of various oxidants to realize the rapid oxidation removal of pollutants.However,in this study,we found that the addition of different oxidants could regulate the redox function of ZVI system.In three different co-treatment systems,the effects of different oxidizers(peroxymonosulfate(PMS),persulfate(PDS),hydrogen peroxide(H_(2)O_(2)))dosages on the ratios of oxidative degradation rate and reductive degradation rate of p-nitrophenol(PNP)were studied.The effect of the H+released from oxidizers and the generated reactive oxygen species(ROS)in ZVI/PMS,ZVI/PDS,ZVI/H_(2)O_(2)systems were detailed discussed.Especially,the contribution of generated ROS for reductive degradation of PNP was quantified in the ZVI/H_(2)O_(2)system.Based on the results of TOC removal,UV-vis absorption spectra,and intermediates concentration curves,it was found that the degradation of PNP changed from reduction to oxidation with the increase of oxidant proportion.When the molar ratio of ZVI to oxidizer equal to 100,PNP was mainly degraded by reduction accompanied by slight oxidation.Combined with the results of SEM-EDS and XPS,it was confirmed that the enhanced degradation of PNP under the addition of oxidant was mainly related to the generated ROS,the additional H+,and the corrosion products of ZVI. | Siqi Zou Qun Chen Yang Liu Yuting Pan Gang Yao Zhicheng Pan Bo Lai | 2021 | Chinese Chemical Letters2021，32，6： | 1 |

| 14 | Three-dimensional-printed polycaprolactone scaffolds with interconnected hollow-pipe structures for enhanced bone regeneration显示文摘Three-dimensional(3D)-printed scaffolds are widely used in tissue engineering to help regenerate critical-sized bone defects.However,conventional scaffolds possess relatively simple porous structures that limit the delivery of oxygen and nutrients to cells,leading to insufficient bone regeneration.Accordingly,in the present study,perfusable and permeable polycaprolactone scaffolds with highly interconnected hollow-pipe structures that mimic natural micro-vascular networks are prepared by an indirect onepot 3D-printing method.In vitro experiments demonstrate that hollow-pipe-structured(HPS)scaffolds promote cell attachment,proliferation,osteogenesis and angiogenesis compared to the normal non-hollow-pipe-structured scaffolds.Furthermore,in vivo studies reveal that HPS scaffolds enhance bone regeneration and vascularization in rabbit bone defects,as observed at 8 and 12weeks,respectively.Thus,the fabricated HPS scaffolds are promising candidates for the repair of critical-sized bone defects. | Jiahua Duan Dong Lei Chen Ling Yufeng Wang Zhicheng Cao Ming Zhang Huikang Zhang Zhengwei You Qingqiang Yao | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
| 15 | Elevated Kir2.1/nuclear N2ICD defines a highly malignant subtype of non-WNT/SHH medulloblastomas显示文摘Medulloblastoma(MB)is one of the most common childhood malignant brain tumors(WHO grade IV),traditionally divided into WNT,SHH,Group 3,and Group 4 subgroups based on the transcription profiles,somatic DNA alterations,and clinical outcomes.Unlike WNT and SHH subgroup MBs,Group 3 and Group 4 MBs have similar transcriptomes and lack clearly specific drivers and targeted therapeutic options.The recently revised WHO Classification of CNS Tumors has assigned Group 3 and 4 to a provisional non-WNT/SHH entity.In the present study,we demonstrate that Kir2.1,an inwardly-rectifying potassium channel,is highly expressed in non-WNT/SHH MBs,which promotes tumor cell invasion and metastasis by recruiting Adam10 to enhance S2 cleavage of Notch2 thereby activating the Notch2 signaling pathway.Disruption of the Notch2 pathway markedly inhibited the growth and metastasis of Kir2.1-overexpressing MB cell-derived xenograft tumors in mice.Moreover,Kir2.1^(high)/nuclear N2ICD^(high)MBs are associated with the significantly shorter lifespan of the patients.Thus,Kir2.1^(high)/nuclear N2ICD^(high)can be used as a biomarker to define a novel subtype of non-WNT/SHH MBs.Our findings are important for the modification of treatment regimens and the development of novel-targeted therapies for non-WNT/SHH MBs. | Yan-Xia Wang Haibo Wu Yong Ren Shengqing Lv Chengdong Ji Dongfang Xiang Mengsi Zhang Huimin Lu Wenjuan Fu Qing Liu Zexuan Yan Qinghua Ma Jingya Miao Ruili Cai Xi Lan Bin Wu Wenying Wang Yinhua Liu Dai-Zhong Wang Mianfu Cao Zhicheng He Yu Shi Yifang Ping Xiaohong Yao Xia Zhang Peng Zhang Ji Ming Wang Yan Wang Youhong Cui Xiu-Wu Bian | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 0 |
| 16 | Biomaterial-induced macrophage polarization for bone regeneration显示文摘As the main target cells of immune regulation,macrophages play an important role in the bone regeneration process.Macrophages can be polarized into the M1 and M2 types under the stimulation of different factors.They have proinflammatory and anti-inflammatory effects,respectively,and play key roles in different stages of bone regeneration.The ratio of M1 to M2 macrophages can be regulated by immunomodulatory biomaterials to promote bone repair and regeneration.In this paper,we review the recent literature on the chemical,physical and biological properties of biomaterials and the regulation of macrophage polarization under the influence of other factors.We also cover new methods for preparing immunomodulatory biomaterials for bone regeneration.This paper will provide new design ideas for the development of biomaterials with immunological properties and will support the clinical translation of bone-related medical biomaterials. | Long Chen Zhicheng Yao Siqin Zhang Kuihan Tang Qiming Yang Yuanzheng Wang Bohan Li Yingjie Nie Xiaobin Tian Li Sun | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
| 17 | Multi-junction cascaded vertical-cavity surface-emitting laser with a high power conversion efficiency of 74%显示文摘High electro-optical conversion efficiency is one of the most distinctive features of semiconductor lasers as compared to other types of lasers.Its further increase remains a significant objective.Further enhancing the efficiency of edgeemitting lasers(EEL),which represent the highest efficiency among semiconductor lasers at present,is challenging.The efficiency of vertical cavity surface emitting lasers(VCSELs)has always been relatively low compared to EEL.This paper,combining modeling with experiments,demonstrates the potential of multi-junction cascaded VCSELs to achieve high efficiency beyond that of EELs,our simulations show,that a 20-junction VCSEL can achieve an efficiency of more than 88%at room temperature.We fabricated VCSEL devices with different numbers of junctions and compared their energy efficiency.15-junction VCSELs achieved a maximum efficiency of 74%at room temperature under nanosecond driving current,the corresponding differential quantum efficiency exceeds 1100%,being the largest electro-optical conversion efficiency and differential quantum efficiency reported until now for VCSELs. | Yao Xiao Jun Wang Heng Liu Pei Miao Yudan Gou Zhicheng Zhang Guoliang Deng Shouhuan Zhou | 2024 | Light(Science & Applications)2024，13，3： | 0 |

| 19 | Lipid-based nanoparticles for cancer immunotherapy显示文摘As the fourth most important cancer management strategy except surgery, chemotherapy and radiotherapy, cancer immunotherapy has been confirmed to elicitdurable antitumor effects in the clinic by leveraging thepatient’s own immune system to eradicate the cancer cells.However, the limited population of patients who benefitfrom the current immunotherapies and the immune relatedadverse events hinder its development. The immunosuppressive microenvironment is the main cause of the failure,which leads to cancer immune evasion and immunity cycleblockade. Encouragingly, nanotechnology has been engineered to enhance the efficacy and reduce off-target toxicityof their therapeutic cargos by spatiotemporally controllingthe biodistribution and release kinetics. Among them, lipidbased nanoparticles are the first nanomedicines to makeclinical translation, which are now established platforms fordiverse areas. In this perspective, we discuss the availablelipid-based nanoparticles in research and market here, thendescribe their application in cancer immunotherapy, withspecial emphasis on the T cells-activated and macrophagestargeted delivery system. Through perpetuating each step ofcancer immunity cycle, lipid-based nanoparticles can reduceimmunosuppression and promote drug delivery to triggerrobust antitumor response. | Shumin Fan Huize Han Zhicheng Yan Yao Lu Bing He Qiang Zhang | 2023 | Medical Review2023，3，3： | 0 |
| 20 | Enhancement of CH_(3)CO^(*) adsorption by editing d-orbital states of Pd to boost C–C bond cleavage of ethanol eletrooxidation显示文摘Improving the complete ethanol electrooxidation on Pd-based catalysts in alkaline media has drawn widely attention due to the high mass energy density.However,the weak adsorption energy of CH_(3)CO^(*) on Pd restricts the C–C bond cleavage.Inspired by the molecular orbital theory,we proposed the d-state-editing strategy to construct more unoccupied d-states of Pd for the enhanced interaction with CH_(3)CO^(*) to break C–C bonds.As expected,the reduced number of e_g electrons and more unoccupied d-states of Pd successfully formed on as-prepared porous Rh Au–Pd Cu nanosheets(PNSs).Theoretical calculations show that the optimized d-states of Rh Au–Pd Cu PNS can effectively improve the adsorption of CH_(3)CO^(*) and drastically reduce the energy barrier of C–C bond cleavage,thus boosting the complete oxidation of ethanol.The charge ratio of C_1 pathway on Rh Au–Pd Cu PNSs is 51.5%,more than 2 times higher than that of Pd NSs.Our finding provides an innovative perspective for the design of highly-efficient noble-based electrocatalysts. | Yuchen Qin Fengqi Wang Pei Liu Jinyu Ye Qian Wang Yao Wang Guangce Jiang Lijie Liu Pengfang Zhang Xiaobiao Liu Xin Zheng Yunlai Ren Junjun Li Zhicheng Zhang | 2024 | Science China Chemistry2024，67，2： | 0 |
