| 1 | Generation of a Hutchinson-Gilford progeria syndrome monkey model by base editing显示文摘Many human genetic diseases,including Hutchinson-Gilford progeria syndrome(HGPS),are caused by single point mutations.HGPS is a rare disorder that causes premature aging and is usually caused by a de novo point mutation in the LMNA gene.Base editors(BEs)composed of a cytidine deaminase fused to CRISPR/Cas9 nickase are highly efficient at inducing C to T base conversions in a programmable manner and can be used to generate animal disease models with single amino-acid substitutions.Here,we generated the first HGPS monkey model by delivering a BE mRNA and guide RNA(gRNA)targeting the LMNA gene via microinjection into monkey zygotes.Five out of six newborn monkeys carried the mutation specifically at the target site.HGPS monkeys expressed the toxic form of lamin A,progerin,and recapitulated the typical HGPS phenotypes including growth retardation,bone alterations,and vascular abnormalities.Thus,this monkey model genetically and clinically mimics HGPS in humans,demonstrating that the BE system can efficiently and accurately generate patient-specific disease models in non-human primates. | Fang Wang Weiqi Zhang Qiaoyan Yang Yu Kang Yanling Fan Jingkuan Wei Zunpeng Liu Shaoxing Dai Hao Li Zifan Li Lizhu Xu Chu Chu Jing Qu Chenyang Si Weizhi Ji Guang-Hui Liu Chengzu Long Yuyu Niu | 2020 | Protein & Cell2020,11,11: | 11 |
| 2 | Crustal accretion and reworking processes of micro-continental massifs within orogenic belt:A case study of the Erguna Massif,NE China显示文摘This paper summarizes the geochronological, geochemical and zircon Hf isotopic data for Mesozoic granitoids within the Erguna Massif, NE China, and discusses the spatial-temporal variation of zircon Hf isotopic compositions, with the aim of constraining the accretion and reworking processes of continental crust within the Erguna Massif, and shedding light on the crustal evolution of the eastern segment of the Central Asian Orogenic Belt. Based on the zircon U-Pb dating results, the Mesozoic granitic magmatisms within the Erguna Massif can be subdivided into five stages: Early-Middle Triassic(249–237 Ma), Late Triassic(229–201 Ma), Early-Middle Jurassic(199–171 Ma), Late Jurassic(155–149 Ma), and Early Cretaceous(145–125 Ma).The Triassic to Early-Middle Jurassic granitoids are mainly I-type granites and minor adakitic rocks, whereas the Late Jurassic to Early Cretaceous granitoids are mainly A-type granites. This change in magmatism is consistent with the southward subduction of the Mongol-Okhotsk oceanic plate and subsequent collision and crustal thickening, followed by post-collision extension. Zircon Hf isotopic data indicate that crustal accretion of the Erguna Massif occurred in the Mesoproterozoic and Neoproterozoic. ZirconεHf(t) values increase gradually over time, whereas two-stage model(TDM2) ages decrease throughout the Mesozoic. The latter result indicates a change in the source of granitic magmas from the melting of ancient crust to more juvenile crust. Zircon εHf(t)values also exhibit spatial variations, with values decreasing northwards, whereas TDM2 ages increase. This pattern suggests that,moving from south to north, there is an increasing component of ancient crustal material within the lower continental crust of the Erguna Massif. Even if at the same latitude, the zircon Hf isotopic compositions are also inconsistent. These results reveal lateral and vertical heterogeneities in the lower continental crust of the Erguna Massif during the Mesozoic, which we use as the basis of a structural and tectonic model for this region. | SUN ChenYang TANG Jie XU WenLiang LI Yu ZHAO Shuo | 2017 | Science China Earth Sciences2017,60,7: | 10 |
| 3 | Oryza sativa FER-LIKE FE DEFICIENCY-INDUCED TRANSCRIPTION FACTOR(OsFIT/OsbHLH156)interacts with OsIRO2 to regulate iron homeostasis显示文摘Iron(Fe)is indispensable for the growth and development of plants.It is well known that FER-LIKE FE DEFICIENCY-INDUCED TRANSCRIPTION FACTOR(FIT)is a key regulator of Fe uptake in Arabidopsis.Here,we identify the Oryza sativa FIT(also known as Osb HLH156)as the interacting partner of IRON-RELATED BHLH TRANSCRIPTION FACTOR 2(OsIRO2)that is critical for regulating Fe uptake.The OsIRO2 protein is localized in the cytoplasm and nucleus,but OsFIT facilitates the accumulation of OsIRO2 in the nucleus.Loss-of-function mutations of OsFIT result in decreased Fe accumulation,severe Fe-deficiency symptoms,and disrupted expression of Feuptake genes.In contrast,OsFIT overexpression promotes Fe accumulation and the expression of Fe-uptake genes.Genetic analyses indicate that OsFIT and OsIRO2 function in the same genetic node.Further analyses suggest that OsFIT and OsIRO2 form a functional transcription activation complex to initiate the expression of Fe-uptake genes.Our findings provide a mechanism understanding of how rice maintains Fe homeostasis. | Gang Liang Huimin Zhang Yang Li Mengna Pu Yujie Yang Chenyang Li Chengkai Lu Peng Xu Diqiu Yu | 2020 | Journal of Integrative Plant Biology2020,62,5: | 4 |

| 5 | Experimental and Numerical Investigation on Erosion Corrosion of the Air Cooler Tube Bundle in a Residue Hydrotreating Unit显示文摘Corrosion leakage occurred in the 14th tube bundle in the first row of a residual oil hydrotreating air cooler after operating for two years.The failure location was 0.5 m from the outlet header box.In this paper,the erosion corrosion of the air cooler tube bundle was investigated by experimental and numerical methods.Visual inspection,scanning electron microscopy(SEM),and X-ray diffraction(XRD)experiments were performed,and the failure morphology and material composition confirmed that the damage was caused by erosion corrosion.The shear stress transport k–ωturbulence model(SST-k–ω)was then used to investigate the flow and erosion corrosion characteristics,combined with mass transfer,corrosion rate,and ionization equilibrium models.The numerical simulation results revealed that the water phase volume fraction increased with flow and heat transfer in the fluid,which increased the mass flow rate and concentration of hydrogen sulfide.The mass transfer coefficient and corrosion rate were proposed as important parameters to characterize erosion corrosion.Moreover,the local concentration of wall shear stress was found to increase the risk of erosion corrosion.The predicted high-risk area was consistent with the actual failure area,which verified that this failure incident was attributable to erosion corrosion by the water phase. | Jin Haozhe Yu Chenyang Gu Youjie Qian Guangwei Liu Xiaofei Ou Guofu Jia Yongna | 2022 | China Petroleum Processing & Petrochemical Technology2022,24,4: | 2 |
| 6 | Pseudo[n,m]rotaxanes of Cucurbit[7/8]uril and Viologen‐Naphthalene Derivative: A Precise Definition of Rotaxane显示文摘Summary of main observation and conclusion Rotaxane is a kind of classic supramolecule, which is usually constructed from a number of macrocycles and one axis molecule. Herein, we have expanded the supramolecular structure of [n]rotaxane to offer a precise definition of (pseudo)[n,m]rotaxane for accurately describing the two kinds of (pseudo)rotaxanes structures, which are self‐assembled from cucurbit[7/8]uril (CB[7/8]) and viologen‐naphthalene derivative, respectively. Furthermore, these CB‐based pseudorotaxanes exhibit varied photophysical properties, stimuli‐responsive behavior triggered by competitive guest, and self‐sorting behavior. | Beilin Zhang Yunhong Dong jie Li Yang Yu Chenyang Li Liping Cao | 2019 | Chinese Journal of Chemistry2019,37,3: | 2 |
| 7 | Mixing and Vaporization Process of Injecting Water in Hydrogenation Unit显示文摘Injecting water into the main pipeline is a common method to prevent the ammonium salt corrosion in hydrogenation units.The use of spray nozzle can enhance the effects of washing ammonium salt and reduce the risk of ammonium salt corrosion.The droplet atomization and evaporation model were used to investigate the mixing process of injecting water and gas-oil mixture in a high-pressure environment.The effects of some key parameters including fluid velocity,temperature,and droplet volume fraction on the mixing and vaporization process were analyzed.Numerical simulation results show that with the increase of injecting water flow rate,the fluid velocity increases and the temperature decreases continuously.When the mass flow rate of injecting water is 1.5 t/h,the droplet has the maximum evaporation efficiency and the volume fraction reaches a minimum value.Besides,with the increase of atomization angle and droplet size,the mean velocity and the temperature of fluid decrease continuously.The increase of atomization angle or the decrease of droplet size will accelerate the evaporation process of droplets and reduce the droplet volume fraction,which indicates that the droplet slip velocity and the contact area are the key factors affecting the droplet evaporation rate. | Liu Xiaofei Yu Chenyang Zhu Haiyan Xu Henghui Jin Haozhe Wang Chao | 2021 | China Petroleum Processing & Petrochemical Technology2021,23,4: | 1 |

| 9 | Recent Advances in Molybdenum-Based Materials for Lithium-Sulfur Batteries显示文摘Lithium-sulfur(Li-S)batteries as power supply systems possessing a theoretical energy density of as high as 2600 Wh kg−1 are considered promising alternatives toward the currently used lithium-ion batteries(LIBs).However,the insulation characteristic and huge volume change of sulfur,the generation of dissolvable lithium polysulfides(LiPSs)during charge/discharge,and the uncontrollable dendrite formation of Li metal anodes render Li-S batteries serious cycling issues with rapid capacity decay.To address these challenges,extensive efforts are devoted to designing cathode/anode hosts and/or modifying separators by incorporating functional materials with the features of improved conductivity,lithiophilic,physical/chemical capture ability toward LiPSs,and/or efficient catalytic conversion of LiPSs.Among all candidates,molybdenum-based(Mo-based)materials are highly preferred for their tunable crystal structure,adjustable composition,variable valence of Mo centers,and strong interactions with soluble LiPSs.Herein,the latest advances in design and application of Mo-based materials for Li-S batteries are comprehensively reviewed,covering molybdenum oxides,molybdenum dichalcogenides,molybdenum nitrides,molybdenum carbides,molybdenum phosphides,and molybdenum metal.In the end,the existing challenges in this research field are elaborately discussed. | Henghan Dai Lumin Wang Yue Zhao Jialu Xue Ruicong Zhou Chenyang Yu Jianing An Jinyuan Zhou Qiang Chen Gengzhi Sun Wei Huang | 2021 | Research2021,,1: | 1 |
| 10 | Unraveling Passivation Mechanism of Imidazolium-Based Ionic Liquids on Inorganic Perovskite to Achieve Near-Record-Efficiency CsPbI_(2)Br Solar Cells显示文摘The application of ionic liquids in perovskite has attracted wide-spread attention for its astounding performance improvement of perovskite solar cells(PSCs).However,the detailed mechanisms behind the improvement remain mysterious.Herein,a series of imidazolium-based ionic liquids(IILs)with different cations and anions is systematically investigated to elucidate the passivation mechanism of IILs on inorganic perovskites.It is found that IILs display the following advantages:(1)They form ionic bonds with Cs^(+)and Pb^(2+)cations on the surface and at the grain boundaries of perovskite films,which could effectively heal/reduce the Cs^(+)/I−vacancies and Pb-related defects;(2)They serve as a bridge between the perovskite and the hole-transport-layer for effective charge extraction and transfer;and(3)They increase the hydrophobicity of the perovskite surface to further improve the stability of the CsPbI_(2)Br PSCs.The combination of the above effects results in suppressed non-radiative recombination loss in CsPbI_(2)Br PSCs and an impressive power conversion efficiency of 17.02%.Additionally,the CsPbI_(2)Br PSCs with IILs surface modification exhibited improved ambient and light illumination stability.Our results provide guidance for an indepth understanding of the passivation mechanism of IILs in inorganic perovskites. | Jie Xu Jian Cui Shaomin Yang Yu Han Xi Guo Yuhang Che Dongfang Xu Chenyang Duan Wenjing Zhao Kunpeng Guo Wanli Ma Baomin Xu Jianxi Yao Zhike Liu Shengzhong Liu | 2022 | Nano-Micro Letters2022,14,1: | 1 |
| 11 | Nonreciprocal coherent coupling of nanomagnets by exchange spin waves显示文摘Nanomagnets are widely used to store information in non-volatile spintronic devices.Spin waves can transfer information with low-power consumption as their propagations are independent of charge transport.However,to dynamically couple two distant nanomagnets via spin waves remains a major challenge for magnonics.Here we experimentally demonstrate coherent coupling of two distant Co nanowires by fast propagating spin waves in an yttrium iron garnet thin film with sub-50 nm wavelengths.Magnons in two nanomagnets are unidirectionally phase-locked with phase shifts controlled by magnon spin torque and spin-wave propagation.The coupled system is finally formulated by an analytical theory in terms of an effective non-Hermitian Hamiltonian.Our results are attractive for analog neuromorphic computing that requires unidirectional information transmission. | Hanchen Wang Jilei Chen Tao Yu Chuanpu Liu Chenyang Guo Song Liu Ka Shen Hao Jia Tao Liu Jianyu Zhang Marco A.Cabero Z Qiuming Song Sa Tu Mingzhong Wu Xiufeng Han Ke Xia Dapeng Yu Gerrit E.W.Bauer Haiming Yu | 2021 | Nano Research2021,14,7: | 1 |

| 13 | Mesh-like vertical structures enable both high areal capacity and excellent rate capability显示文摘In order to balance electrochemical kinetics with loading level for achieving efficient energy storage with high areal capacity and good rate capability simultaneously for wearable electronics,herein,2 D meshlike vertical structures(NiCo_2 S_4@Ni(OH)_2) with a high mass loading of 2.17 mg cm^(-2) and combined merits of both 1 D nanowires and 2 D nanosheets are designed for fabricating flexible hybrid supercapacitors.Particularly,the seamlessly interconnected NiCo_2 S_4 core not only provides high capacity of 287.5 μAh cm^(-2) but also functions as conductive skeleton for fast electron transport;Ni(OH)_2 sheath occupying the voids in NiCo_2 S_4 meshes contributes extra capacity of 248.4 μAh cm^(-2);the holey features guarantee rapid ion diffusion along and across NiCO_2 S_4@Ni(OH)_2 meshes.The resultant flexible electrode exhibits a high areal capacity of 535.9 μAh cm^(-2)(246.9 mAh g^(-1)) at 3 mA cm^(-2) and outstanding rate performance with 84.7% retention at 30 mA cm^(-2),suggesting efficient utilization of both NiCo_2 S_4 and Ni(OH)_2 with specific capacities approaching to their theoretical values.The flexible solid-state hybrid device based on NiCo_2 S_4@Ni(OH)_2 cathode and Fe_2 O_3 anode delivers a high energy density of 315 μWh cm^(-2) at the power density of 2.14 mW cm^(-2) with excellent electrochemical cycling stability. | Ruyi Chen Jialu Xue Yujiao Gong Chenyang Yu Zengyu Hui Hai Xu Yue Sun Xi Zhao Jianing An Jinyuan Zhou Qiang Chen Gengzhi Sun Wei Huang | 2021 | Journal of Energy Chemistry2021,30,2: | 1 |
| 14 | Risk SNP-induced lncRNA-SLCCl drives colorectal cancer through activating glycolysis signaling显示文摘Long non-coding RNAs(lncRNAs)play key roles in colorectal carcinogenesis.Here,we aimed to identify the risk SNP-induced lncRNAs and to investigate their roles in colorectal carcinogenesis.First,we identified rs6695584 as the causative SNP in 1 q41 locus.The A>G mutation of rs6695584 created a protein-binding motif of BATF,altered the enhancer activity,and subsequently activated IncSLCCl expression.Further validation in two independent CRC cohorts confirmed the upregulation of IncSLCCl in CRC tissues,and revealed that increased IncSLCCl expression was associated with poor survival in CRC patients.Mechanistically,lncRNA-SLCCl interacted with AHR and transcriptionally activated HK2 expression,the crucial enzyme in glucose metabolism,thereby driving the glycolysis pathway and accelerating CRC tumor growth.The functional assays revealed that IncSLCCl induced glycolysis activation and tumor growth in CRC mediated by HK2.In addition,HK2 was upregulated in colorectal cancer tissues and positively correlated with IncSLCCl expression and patient survival.Taken together,our findings reveal a risk SNP-mediated oncogene lncRNA-SLCCl promotes CRC through activating the glycolysis pathway. | Tingting Yan Chaoqin Shen Penglei Jiang Chenyang Yu Fangfang Guo Xianglong Tian Xiaoqiang Zhu Shiyuan Lu Bingshe Han Ming Zhong Jinxian Chen Qiang Liu Yingxuan Chen Junfang Zhang Jie Hong Haoyan Chen Jing-Yuan Fang | 2021 | Signal Transduction and Targeted Therapy2021,6,3: | 1 |

| 16 | High lithiophilic nitrogen-doped carbon nanotube arrays prepared by in-situ catalyze for lithium metal anode显示文摘Lithium metal has a very outstanding theoretical capacity(3860 mAh/g)and is one of the most superior anode materials for high energy density batteries.However,the uncontrollable dendrite growth and the fo rmation of'dead lithium'are the important hidden dangers of short cycle life and low safety.However,the uncontrollable dendrite growth and the fo rmation of dead lithium leads to short cycle life and hidden dange r,which hinder its practical application.Controlling the nucleation and growth process of lithium is an effective strategy to inhibit lithium dendrite.Herein,a simple in situ self-catalytic method is used to construct nitrogen doped carbon nanotube arrays on stainless steel mesh(N-CNT@SS)as a lithium composite anode.The N-doped CNTs provide a great number of N-functional groups,which enhance the lithiophilic of anode and provide a large number of uniform nucleation sites,hence it has excellent structural stability for cycles.The arrays provide neat lithium-ion transport channels to uniform lithiumion flux and inhibits dendrite generation,revealed by the COMSOL multi-physics concentration field simulation.The N-CNT@SS composite anode sustain stable at 98.9%over 300 cycles at 1 mA/cm2.NCNT@SS as the anode is coupled LiFePO_(4)(LFP)as the cathode construct a full battery,demonstrating excellent cycling stability with a capacity of 152.33 mAh/g and capacity retaining ratio of 95.4%after 100 cycles at 0.5 C. | Chenyang Zhao Xiaoju Yin Zhikun Guo Dan Zhao Guiye Yang Aosai Chen Lishuang Fan Yu Zhang Naiqing Zhang | 2021 | Chinese Chemical Letters2021,32,7: | 1 |
| 17 | Rationale and Study Design for Evaluating the Efficacy and Safety of Intracardiac Echocardiography-Guided Minimal-Fluoroscopy Ablation in Patients with Paroxysmal Atrial Fibrillation:A Non-Inferior,Multi-Center,Prospective Randomized Controlled Trial(PAF-ICE Trial)显示文摘The feasibility and safety of intracardiac echocardiography(ICE)-guided catheter ablation for atrial fibrillation(AF)using a minimal/zero-fluoroscopy approach have recently been reported.This approach helps to reduce ionizing radiation exposure and orthopedic complications resulting from using lead aprons.The objectives of this planned prospective,multicenter randomized controlled trial(RCT)(paroxysmal AF(PAF)-ICE trial;ChiCTR2000033624)are to evaluate the efficacy and safety of ICE-guided minimal-fluoroscopy ablation in patients with PAF and the impact on occupational hazards among lab staff.Patients will be randomized in a 1:1 ratio to 2 groups:minimal fluoroscopy group(n=216)and traditional approach group(n=216).In the minimal fluoroscopy group,an ICE catheter will be used for geometry/anatomic construction,transseptal puncture,catheter tracking,and effusion monitoring.Pulmonary vein isolation(PVI)will be performed using an open-irrigated radiofrequency SmartTouch Surround Flow or SmartTouch catheter(Biosense Webster,Diamond Bar,California,USA),and confirmed by a multipolar Lasso or PentaRay catheter(Biosense Webster).In the traditional approach group,an ICE catheter will not be used.Transseptal puncture will be performed under fluoroscopic guidance,with all geometries constructed by mapping the catheters.The primary efficacy endpoint is freedom from AF recurrence(without antiarrhythmic medications)at 12months after ablation.Other endpoints include duration of lead apron use,measures of intra-procedural efficiency,and peri-procedural complications.This RCT will evaluate the efficacy and safety of ICE-guided minimal-fluoroscopy ablation in patients with PAF,also evaluate the benefits to lab staff(regarding reducing occupational hazards)related to this“minimal/zero-fluoroscopy”and“leadless”mode. | Ruhong Jiang Xingpeng Liu Jidong Zhang Yu Chen Rui Wang Mengzuo Wu Deyong Long Jia Li Haixiong Wang Jie Fan Weizhu Ju Weili Ge Xu Liu Hai Deng Weijian Wang Pingzhen Yang Ding Li Xiaobo Huang Xiongtao Liu Hailong Tao Paul CZei Roderick Tung Xunzhang Wang Chenyang Jiang | 2021 | Cardiology Discovery2021,1,4: | 1 |

| 20 | A flame-retardant binder with high polysulfide affinity for safe and stable lithium–sulfur batteries显示文摘Lithium-sulfur(Li-S) batteries have shown promises for the next-generation, high-energy electrochemical storage, yet are hindered by rapid performance decay due to the polysulfide shuttle in the cathode and safety concerns about potential thermal runaway. To address the above challenges, herein, we show a flame-retardant cathode binder that simultaneously improves the electrochemical stability and safety of batteries. The combination of soft and hard segments in the polymer framework of binders allows high flexibility and mechanical strength for adapting to the drastic volume change during the Li(de)intercalation of the S cathode. The binder contains a large number of polar groups, which show the high affinity to polysulfides so that they help to anchor active S species at the cathode. These polar groups also help to regulate and facilitate the Li-ion transport, promoting the kinetics of polysulfide conversion reaction. The binder contains abundant phosphine oxide groups, which, in the case of battery's thermal runaway, decompose and release PO· radicals to quench the combustion reactions and stop the fire. Consequently, Li-S batteries using the new cathode binder show the improved electrochemical performance, including a low-capacity decay of 0.046% per cycle for 800 cycles at 1 C and favorable rate capabilities of up to 3 C. This work offers new insights on the practical realization of high-energy rechargeable batteries with stable storage electrochemistry and high safety. | Guowei Yu Guofeng Ye Cheng Wang Chenyang Wang Zhaoyun Wang Pu Hu Yu Li Xi-Xi Feng Shuang-Jie Tan Min Yan Sen Xin Zhitian Liu | 2024 | Science China Chemistry2024,67,3: | 0 |
