| 1 | N-doped defective carbon with trace Co for efficient rechargeable liquid electrolyte-/all-solid-state Zn-air batteries显示文摘Simple synthesis of multifunctional electrocatalysts with plentiful active sites from earth-abundant materials is especially fascinating. Here, N-doped defective carbon with trace Co(1.5 wt%) was prepared via a scalable one pot solid pyrolysis process. The sample exhibits efficient bifunctional OER/ORR activity in alkaline, mainly ascribed to the unique micro-mesoporous structure(1–3 nm), high population of graphitic-N doping(up to 49.0%), abundant defects and the encapsulated Co nanoparticles with graphitized carbon. The according rechargeable liquid Zn-air batteries showed excellent performance(maximum power density of 154.0 mW cm^(-2); energy density of 773 Wh kg^(-1) at 5 mA cm^(-2) and charging-discharging cycling stability over 100 cycles). As a proof-of-concept, the flexible, rechargeable all-solid-state Zn-air batteries were constructed, and displayed a maximum power density as high as 45.9 mW cm^(-2), among the top level of those reported previously. | Zhiyan Chen Qichen Wang Xiaobin Zhang Yongpeng Lei Wei Hu Yao Luo Yaobing Wang | 2018 | Science Bulletin2018,63,9: | 14 |
| 2 | Extraordinary simultaneous enhancement of the coercivity and remanence of dual alloy HRE-free Nd-Fe-B sintered magnets by post-sinter annealing显示文摘Post-sinter annealing process plays an important role in the microstructures and magnetic properties of the Nd-Fe-B sintered magnets.In this paper,systematically investigated are the magnetic properties and microstructures of the as-sintered and post-sinter annealed Nd-Fe-B magnets with Pr-Fe-Ga boundary addition.Two choice consecutive annealing methods are adopted at high and low temperatures,namely the 1 st annealing at 880℃ for 2 h and then the 2^(nd) annealing at 440℃ for 3 h.It is exceptional to find out that both the remanence and coercivity are improved after 2^(nd) annealing process for this type of magnet.The coercivity is hugely increased from 10.09 kOe for the as-sintered sample to 17.19 kOe for the 2^(nd) annealed magnet,with a significant increment of 70.37%in coercivity.The extraordinary magnetic properties of B_(r)=14.44 kGs,H_(cj)=17.19 kOe and(BH)_(max)=51.08 MGOe are obtained for the designated Nd-Fe-B sintered magnets without heavy rare earth(HRE)elements manufactured by dual alloy method.The Curie temperature is monotonically decreased from 634 K to 602 K while the c-axis alignment degree is optimized after annealing.Microstructural observation and analysis indicate that the elemental distribution patterns are altered after the 2^(nd) annealing.The diffusion of the aggregate(Pr,Nd,Cu,Ga)-rich phase from triple junctions into the grain boundary regions is ascribed to the formation of thin and continuous grain boundary layer,which is critical to improve the microstructures and magnetic properties. | Qingfang Huang Qingzheng Jiang Jifan Hu Sajjad Ur Rehman Gang Fu Qichen Quan Jixiang Huang Deqin Xu Dakun Chen Zhenchen Zhong | 2022 | Journal of Materials Science & Technology2022,,11: | 3 |
| 3 | Trimetallic oxyhydroxides as active sites for large-current-density alkaline oxygen evolution and overall water splitting显示文摘Earth-abundant electrocatalysts for large-current-density water splitting under alkaline condition are desirable.Oxygen evolution reaction,which is a bottleneck of the overall water splitting,faces the problems of complicated reconstruction and deficiency in rational design of active sites.Herein,we report a series of transition metal chalcogenides for alkaline OER.Among them,FeCoNi(S)displayed a low overpotential of 293 m V to deliver a current density of 500 m A cm^(-2),which is in the top level of non-precious metal based OER electrocatalysts.A combination of(ex)in situ characterizations and DFT calculation shows that Ni(Fe,Co)trimetallic oxyhydroxides were the active sites for highly-efficient OER.Furthermore,for FeCoNi(S),when used as a bifunctional catalyst for water splitting,it only required a cell voltage of 1.84 V to deliver~500 m A cm^(-2) with extraordinary long-term stability over 2000 h.This work provides the comprehension of high-efficiency,robust catalysts for OER and overall water splitting at large current densities in alkaline media. | Lei Chen Yunpeng Wang Xin Zhao Yuchao Wang Qian Li Qichen Wang Yougen Tang Yongpeng Lei | 2022 | Journal of Materials Science & Technology2022,,15: | 3 |

| 6 | Oxygen-rich carbon-nitrogen quantum dots as cocatalysts for enhanced photocatalytic H_2 production activity of TiO_2 nanofibers显示文摘We developed an one-step hydrothermal method to synthesize carbon-nitrogen quantum dots(CNQDs) with oxygen-rich functional groups.The sample was characterized by TEM,AFM,FT-IR,XPS,UV-vis absorption and PL spectra.The 0/C and N/C atomic ratio of typical CNQDs with diameters of 3-6 nm are ca.0.4 and 0.2,respectively.Without noble metal cocatalyst,the photocatalytic H_2 production rate of CNQDs/TiO_2 nanofibers(NFs)(112.4 μmol h^(-1) g^(-1)) is 1.8 times higher than that of TiO_2 NFs.The good absorption of light contributes to the enhanced photocatalytic H_2 performance.The CNQDs could be promising in biomedical imaging,optical data recording storage and photo/electrocatalysis,etc. | Zhiyan Chen Yishang Wu Qichen Wang Zhiyong Wang Lihua He Yongpeng Lei Zhongmin Wang | 2017 | Progress in Natural Science:Materials International2017,27,3: | 1 |

| 10 | Potential active sites of Mo single atoms for electrocatalytic reduction of N_(2)显示文摘Single atom catalysts(SACs) with isolated metal atoms dispersed on supports exhibit distinctive performances for electrocatalysis reactions.The designable realization of well-dispersed single metal atoms is still a great challenge owing to their ease of aggregation.Here,Mo single atomic sites(Mo-N_(3)C)combined with some ultrasmall Mo_(2)C/MoN clusters(Mo-SA/Mo_(2)C-MoN-Cs,mean diameter <2 nm) on nitrogen-doped porous carbon were synthesized via a simple pyrolysis of bimetallic Zn/Mo metalorganic frameworks.X-ray absorption near edge spectra(XANES) in combination with various characterizations show that most of Mo species in sample exist in the form of single sites and the exact structure is Mo-N_(3)C.Density functional theory(DFT) calculation further shows that as the number of Ncoordination in the Mo-NxC moieties increases,the positive cha rge of Mo atoms increases.The single Mo atoms in Mo-N_(3)C have the best capability of N_(2) adsorption,which may serve as main active sites for further electrochemical N2 reduction. | Lei Chen Chaozheng He Ran Wang Qian Li Jian Zeng Wei Liu Yuchao Wang Qichen Wang Tong Ye Yougen Tang Yongpeng Lei | 2021 | Chinese Chemical Letters2021,32,1: | 1 |
| 11 | A reference-grade genome assembly for Astragalus mongholicus and insights into the biosynthesis and high accumulation of triterpenoids and flavonoids in its roots显示文摘Astragalus membranaceus var.mongholicus(AMM),a member of the Leguminosae,is one of the most important medicinal plants worldwide.The dried roots of AMM have a wide range of pharmacological effects and are a traditional Chinese medicine.Here,we report the first chromosome-level reference genome of AMM,comprising nine pseudochromosomes with a total size of 1.47 Gb and 27868 protein-encoding genes.Comparative genomic analysis reveals that AMM has not experienced an independent wholegenome duplication(WGD)event after the WGD event shared by the Papilionoideae species.Analysis of long terminal repeat retrotransposons suggests a recent burst of these elements at approximately 0.13 million years ago,which may explain the large size of the AMM genome.Multiple gene families involved in the biosynthesis of triterpenoids and flavonoids were expanded,and our data indicate that tandemduplication has been the main driver for expansion of these families.Among the expanded families,the phenylalanine ammonia-lyase gene family was primarily expressed in the roots of AMM,suggesting their roles in the biosynthesis of phenylpropanoid compounds.The functional versatility of 2,3-oxidosqualene cyclase genes in cluster Ⅲ may play a critical role in the diversification of triterpenoids in AMM.Our findings provide novel insights into triterpenoid and flavonoid biosynthesis and can facilitate future research on the genetics and medical applications of AMM. | Yi Chen Ting Fang He Su Sifei Duan Ruirui Ma Ping Wang Lin Wu Wenbin Sun Qichen Hu Meixia Zhao Lianjun Sun Xuehui Dong | 2023 | Plant Communications2023,4,2: | 0 |
| 12 | Novel gold nanoparticles targeting somatostatin receptor subtype two with near-infrared light for neuroendocrine tumour therapy显示文摘Neuroendocrine tumours(NETs)are rare cancers with positive somatostatin receptor 2(SSTR2)expression,and treatment strategies for NETs are not satisfactory.Nanomaterial-mediated therapy targeting SSTR2 in NETs is very promising.This study firstly combined mesoporous silica-coated gold nanorods(AuNRs@mSiO_(2))and targeting-SSTR2 dodecane tetraacetic acidtyrosine3-octreotate(DOTA-TATE)into AuNRs@mSiO_(2)@DOTA-TATE to investigate NETs inhibition under near-infrared light.AuNRs@mSiO_(2)@DOTA-TATE showed good photothermal conversion efficiency.In vitro,under light irradiation,the cell viability significantly decreased with increasing AuNR@mSiO_(2)@DOTA-TATE concentration;in two successfully established neuroendocrine tumour organoids with SSTR2 expression,AuNRs@mSiO_(2)@DOTA-TATE with light inhibited tumours significantly better than AuNRs@mSiO_(2) with light.In vivo,the SSTR2-targeting ability and biodistribution of AuNRs@mSiO_(2)@DOTA-TATE were confirmed with AuNRs@mSiO_(2)@64Cu-DOTA-TATE under micro-positron emission tomography/computed tomography(micro-PET/CT);in the AuNRs@mSiO_(2)@DOTA-TATE with laser group,the tumour surface temperature increased rapidly,with tumour volumes similar to those in the octreotide group and significantly lower than those in other groups.There was no significant difference in mice body weight between the AuNRs@mSiO_(2)@DOTA-TATE with laser group and other groups.No significant inflammatory lesions or cell necrosis was found in the main organs.In summary,we presented a feasible strategy to construct AuNRs@mSiO_(2)@DOTA-TATE with good photothermal conversion efficiency,targetingSSTR2 ability,significant antitumour effects,and good biocompatibility,warranting further explorations of AuNRs@mSiO_(2)@DOTA-TATE for NETs therapy applications. | Qichen Chen Zilin Li Jiangyuan Yu Qing Xie Haizhen Lu Yiqiao Deng Jinghua Chen Wenjia Zhu Li Huo Yizhou Zhang Wei Song Jianqiang Lan Jianqiang Cai Zhen Huang Zixi Wang Hong Zhao | 2022 | Nano Research2022,15,10: | 0 |
| 13 | RING finger 138 deregulation distorts NF-κB signaling and facilities colitis switch to aggressive malignancy显示文摘Prolonged activation of nuclear factor(NF)-кB signaling significantly contributes to the development of colorectal cancer(CRC).New therapeutic opportunities are emerging from targeting this distorted cell signaling transduction.Here,we discovered the critical role of RING finger 138(RNF138)in CRC tumorigenesis through regulating the NF-кB signaling,which is independent of its Ubiquitin-E3 ligase activity involved in DNA damage response.RNF138^(−/−) mice were hyper-susceptible to the switch from colitis to aggressive malignancy,which coincided with sustained aberrant NF-кB signaling in the colonic cells.Furthermore,RNF138 suppresses the activation of NF-кB signaling pathway through preventing the translocation of NIK and IKK-Beta Binding Protein(NIBP)to the cytoplasm,which requires the ubiquitin interaction motif(UIM)domain.More importantly,we uncovered a significant correlation between poor prognosis and the downregulation of RNF138 associated with reinforced NF-кB signaling in clinical settings,raising the possibility of RNF138 dysregulation as an indicator for the therapeutic intervention targeting NF-кB signaling.Using the xenograft models built upon either RNF138-dificient CRC cells or the cells derived from the RNF138-dysregulated CRC patients,we demonstrated that the inhibition of NF-кB signaling effectively hampered tumor growth.Overall,our work defined the pathogenic role of aberrant NF-кB signaling due to RNF138 downregulation in the cascade events from the colitis switch to colonic neoplastic transformation and progression,and also highlights the possibility of targeting the NF-кB signaling in treating specific subtypes of CRC indicated by RNF138-ablation. | Yalan Lu Rong Huang Jianming Ying Xingchen Li Tao Jiao Lei Guo Haitao Zhou Han Wang Amannisa Tuersuntuoheti Jianmei Liu Qichen Chen Yanhong Wang Luying Su Changyuan Guo Fu Xu Ziyi Wang Yan Lu Kai Li Junbo Liang Zhen Huang Xiao Chen Jinjie Yao Hanjie Hu Xiaowen Cheng Yufeng Wan Xinyan Chen Ning Zhang Shiying Miao Jianqiang Cai Linfang Wang Changzheng Liu Wei Song Hong Zhao | 2022 | Signal Transduction and Targeted Therapy2022,7,7: | 0 |

| 15 | One-step hydrothermal synthesis of Cit-NaYbF_(4):Er^(3+)nanocrystals with enhanced red upconversion emission for in vivo fluorescence molecular tomography显示文摘Fluorescence imaging techniques represent essential tools in in vitro,preclinical,and clinical studies.In this study,an improved one-step hydrothermal method to synthesize citric acid(CA)modifiedα-NaYbF_(4):2%Er^(3+)nanocrystals was proposed.The introduction of various doping ions into NaYbF_(4):2%Er^(3+)and the different valence states of the same ions affect both the crystal size and upconversion luminesce nce.There fore,we investigated the upconversion luminesce nce enha ncement of NaYbF_(4):2%Er^(3+)by ion doping and find that the upconversion luminescence intensity of the upconversion nanoparticles(UCNPs)co-doped with 5 mol%Fe^(2+)ions shows the greatest enhancement,especially for red emission at654 nm.Furthermore,HeLa cells incubated with UCNPs allow for imaging with strong red upconversion emission detectio n.Confocal laser scanning microscope(CLSM)fluorescent images of HeLa cells indicate that NaYbF_(4):2%Er/5%Fe^(2+)leads to a clear outline and improves visualization of the cell morphology.In addition,the CA coated NaYbF_(4):2%Er^(3+)/5%Fe^(2+)nanoparticles and NaYbF_(4):2%Er^(3+)/5%Fe^(2+)show low cytotoxicity in HeLa cells.Organ imaging reveals the efficiency of these UCNPs to analyze the lungs,liver,and spleen.Together,these results indicate that the Cit-NaYbF_(4):2%Er^(3+)/5%Fe^(2+)UCNPs are efficient nanoprobes for fluorescence molecular to mography. | Xiaoli Luo Qichen Chen Hongbo Guo Heng Zhang Xiaowei He Wu Zhao | 2024 | Journal of Rare Earths2024,42,1: | 0 |

| 17 | Phosphating-induced charge transfer on CoO/CoP interface for alkaline H_(2)evolution显示文摘Designing non-noble metal electrocatalysts toward alkaline hydrogen evolution reaction(HER)with high performance at a large current density is urgent.Herein,a CoO/CoP heterostructure catalyst(termed POZ)was designed by a phosphating strategy.The strong electron transfer on the interface of CoO/CoP was experimentally and theoretically proven.POZ showed a low overpotential of 236 mV at 400 mA/cm^(2),which was 249 mV lower than non-phosphated sample.It also exhibited a remarkable solar-to-hydrogen conversion efficiency of 10.5%.In this work,the construction of CoO/CoP interface realized by a simple phosphating strategy could provide an important reference to boost the HER performance on those materials not merely metal oxides. | Qian Li Yuchao Wang Jian Zeng Qiumei Wu Qichen Wang Lian Sun Liang Xu Tong Ye Xin Zhao Lei Chen Zhiyan Chen Limiao Chen Yongpeng Lei | 2021 | Chinese Chemical Letters2021,32,11: | 0 |
