| 2 | Review of soot measurement in hydrocarbon-air flames显示文摘Soot,which is produced in fuel-rich parts of flames as a result of incomplete combustion of hydrocarbons,is the No.2 contributor to global warming after carbon dioxide.Developing soot measurement techniques is important to understand soot formation mechanism and control soot emission.The various soot measurement techniques,such as thermophoretic sampling par-ticles diagnostics followed by electron microscopy analysis,thermocouple particle densitometry,light extinction,laser-induced incandescence,two-color method,and emission computed tomography,are reviewed in this paper.The measurement principle and application cases of these measurement methods are described in detail.The development trend of soot measurement is to realize the on-line measurement of multi-dimensional distributions of temperature,soot volume fraction,soot particle size and other parameters in hydrocarbon-air flames.Soot measurement techniques suitable for both small flames in laboratories and large-scale flames in industrial combustion devices should be developed.Besides,in some special situations,such as high-pressure,zero gravity and micro-gravity flames,soot measurement also should be provided. | LOU Chun,CHEN Chen,SUN YiPeng&ZHOU HuaiChun State Key Laboratory of Coal Combustion,Huazhong University of Science and Technology,Wuhan 430074,China | 2010 | Science China(Technological Sciences)2010，53，8： | 13 |
| 3 | SRSF1 plays a critical role in invariant natural killer T cell development and function显示文摘Invariant natural killer T(iNKT)cells are highly conserved innate-like T lymphocytes that originate from CD4^(+)CD8^(+)double-positive(DP)thymocytes.Here,we report that serine/arginine splicing factor 1(SRSF1)intrinsically regulates iNKT cell development by directly targeting Myb and balancing the abundance of short and long isoforms.Conditional ablation of SRSF1 in DP cells led to a substantially diminished iNKT cell pool due to defects in proliferation,survival,and TCRαrearrangement.The transition from stage 0 to stage 1 of iNKT cells was substantially blocked,and the iNKT2 subset was notably diminished in SRSF1-deficient mice.SRSF1 deficiency resulted in aberrant expression of a series of regulators that are tightly correlated with iNKT cell development and iNKT2 differentiation,including Myb,PLZF,Gata3,ICOS,and CD5.In particular,we found that SRSF1 directly binds and regulates pre-mRNA alternative splicing of Myb and that the expression of the short isoform of Myb is substantially reduced in SRSF1-deficient DP and iNKT cells.Strikingly,ectopic expression of the Myb short isoform partially rectified the defects caused by ablation of SRSF1.Furthermore,we confirmed that the SRSF1-deficient mice exhibited resistance to acute liver injury uponα-GalCer and Con A induction.Our findings thus uncovered a previously unknown role of SRSF1 as an essential post-transcriptional regulator in iNKT cell development and functional differentiation,providing new clinical insights into iNKT-correlated disease. | Jingjing Liu Menghao You Yingpeng Yao Ce Ji Zhao Wang Fang Wang Di Wang Zhihong Qi Guotao Yu Zhen Sun Wenhui Guo Juanjuan Liu Shumin Li Yipeng Jin Tianyan Zhao Hai-Hui Xue Yuanchao Xue Shuyang Yu | 2021 | Cellular & Molecular Immunology2021，18，11： | 3 |
| 4 | Nitrogen doped FeS_(2) nanoparticles for efficient and stable hydrogen evolution reaction显示文摘Performance breakthrough of electrocatalysts highly relies on the regulation of internal structures and electronic states.In present work,for the first time,we successfully synthesized nitrogen doped FeS_(2) nanoparticles(N-FeS_(2))as the electrocatalysts for hydrogen evolution reaction(HER).The band structure and electronic state of FeS_(2) are modulated by a nitrogen doping strategy,as confirmed by X-ray photoelectron spectroscopy(XPS),X-ray absorption spectroscopy(XAS)and density functional theory(DFT)calculations.Owing to the band structure and electronic state regulation as well as the weakening of H-S interaction,the designed N-FeS_(2) electrocatalyst exhibits superior catalytic performance with a low overpotential(~126 mV at 10 mA cm^(-2))and excellent activity stability under alkaline conditions,which is substantially improved as compared with that of the pure FeS_(2) counterpart.Our work demonstrates that the modulation of electron state and band structure of an electrocatalyst,which can provide a valuable guidance for designing excellent catalysts for hydrogen evolution reaction and beyond. | Jian Ye Yipeng Zang Qingyu Wang Yida Zhang Da Sun Leijie Zhang Gongming Wang Xusheng Zheng Junfa Zhu | 2021 | Journal of Energy Chemistry2021，30，5： | 2 |

| 6 | Rice FLOURY ENDOSPERM22, encoding a pentatricopeptide repeat protein, is involved in both mitochondrial RNA splicing and editing and is crucial for endosperm development显示文摘Most of the reported P-type pentatricopeptide repeat(PPR) proteins play roles in organelle RNA stabilization and splicing. However, P-type PPRs involved in both RNA splicing and editing have rarely been reported, and their underlying mechanism remains largely unknown. Here, we report a rice floury endosperm22(flo22) mutant with delayed amyloplast development in endosperm cells. Map-based cloning and complementation tests demonstrated that FLO22 encodes a mitochondrion-localized P-type PPR protein.Mutation of FLO22 resulting in defective transsplicing of mitochondrial nad1 intron 1 and perhaps causing instability of mature transcripts affected assembly and activity of complex Ⅰ, and mitochondrial morphology and function. RNA-seq analysis showed that expression levels of many genes involved in starch and sucrose metabolism were significantly down-regulated in the flo22mutant compared with the wild type, whereas genes related to oxidative phosphorylation and the tricarboxylic acid cycle were significantly upregulated. In addition to involvement in splicing as a P-type PPR protein, we found that FLO22 interacted with DYW3, a DYW-type PPR protein, and they may function synergistically in mitochondrial RNA editing. The present work indicated that FLO22 plays an important role in endosperm development and plant growth by participating in nad1 maturation and multi-site editing of mitochondrial messager RNA. | Hang Yang Yunlong Wang Yunlu Tian Xuan Teng Zehui Lv Jie Lei Erchao Duan Hui Dong Xue Yang Yuanyan Zhang Yinglun Sun Xiaoli Chen Xiuhao Bao Rongbo Chen Chuanwei Gu Yipeng Zhang Xiaokang Jiang Wenyu Ma Pengcheng Zhang Yi Ji Yu Zhang Yihua Wang Jianmin Wan | 2023 | Journal of Integrative Plant Biology2023，65，3： | 1 |

| 8 | Orbital-regulated interfacial electronic coupling endows Ni3N with superior catalytic surface for hydrogen evolution reaction显示文摘The interstitial structure and weak Ni-N interaction of Ni3N lead to high unoccupied d orbital energy and unsuitable orbital orientation,which consequently results in weak orbital coupling with H2O and slow water dissociation kinetics for alkaline hydrogen evolution catalysis.Herein,we successfully lower the unoccupied d orbital energy of Ni3N to strengthen the interfacial electronic coupling by employing the strong electron pulling capability of oxygen dopants.The prepared O-Ni3N catalyst delivers an overpotential of 55 mV at 10 mA cm−2,very close to the commercial Pt/C.Refined structural characterization indicates the oxygen incorporation can decrease the electron densities around the Ni sites.Moreover,density functional theory calculation further proves the oxygen incorporation can create more unoccupied orbitals with lower energy and superior orientation for water adsorption and dissociation.The concept of orbital-regulated interfacial electronic coupling could offer a unique approach for the rational design of hydrogen evolution catalysts and beyond. | Yanyan Fang Da Sun Shuwen Niu Jinyan Cai Yipeng Zang Yishang Wu Linqin Zhu Yufang Xie Yun Liu Zixuan Zhu Amirabbas Mosallanezhad Di Niu Zheng Lu Junjie Shi Xiaojing Liu Dewei Rao Gongming Wang Yitai Qian | 2020 | Science China Chemistry2020，63，11： | 1 |

| 10 | Gd_(2)O_(3) nanoparticles modified g-C_(3)N_(4) with enhanced photocatalysis activity for degradation of organic pollutants显示文摘Gd_(2) O_(3) nanoparticles modified g-C_(3) N_(4) photocatalytic composites were synthesized by a simple one-step hydrothermal method.The structure,morphology,optical properties of the prepared photocatalyst were characterized by X-ray diffraction(XRD),field emission scanning electron microscopy(FESEM),field emission transmission electron microscopy(FETEM) and X-ray photoelectron spectroscopy(XPS).The result demonstrates that gadolinium is mainly dispersed on the surface of g-C_(3) N_(4) in the form of Gd_(2) O_(3),and does not destroy the lattice structure of g-C_(3) N_(4).Besides,the gadolinium can cause the red shift of the absorption edge of light,narrow the band gap,and increase the separation efficiency of the photogenerated electron and hole of g-C_(3) N_(4).Especially,the specific surface area of g-C_(3) N_(4) can be significantly increased.Furthermore,g-C_(3) N_(4)/Gd-0.05 displays the highest photodegradation performance when it is used for degradation of methyl orange(MO),methylene blue(MB) and Rhodamine B(RhB).The photodegradation rate of g-C_(3) N_(4)/Gd-0.05 composites is 72.4% for MO,95.5% for RhB,100% for MB after120 min under visible light(λ> 420 nm) irradiation.Narrow band gap promotes the separation of photogenerated electron and hole,which enhances the photocatalytic activity of g-C_(3) N_(4).It is noted that g-C_(3) N_(4)/Gd-0.05 exhibits excellent photocatalytic stability by the photocurrent and the cyclic photodegradation of MO. | Yipeng Zhou Fanshan Zeng Chaoyang Sun Jun Wu Yu Xie Fayun Zhang Senlin Rao Fahui Wang Jinbing Zhang Jinsheng Zhao Shiqian Li | 2021 | Journal of Rare Earths2021，39，11： | 1 |

| 14 | Accelerating water dissociation kinetics of Ni3N by tuning interfacial orbital coupling显示文摘The high unoccupied d band energy of Ni_(3)N basically results in weak orbital coupling with water molecule,consequently leading to slow water dissociation kinetics.Herein,we demonstrate Cr doping can downshift the unoccupied d orbitals and strengthen the interfacial orbital coupling to boost the water dissociation kinetics.The prepared Cr-Ni_(3)N/Ni displays an impressive overpotential of 37 mV at 10 mA·cmgeo-2,close to the benchmark Pt/C in 1.0 M KOH solution.Refined structural analysis reveals the Cr dopant exists as the Cr-N_(6)states and the average d band energy of Ni_(3)N is also lowered.Density functional theory calculation further confirms the downshifted d band energy can strengthen the orbital coupling between the unpaired electrons in O 2p and the unoccupied state of Ni 3d,which thus facilitates the water adsorption and dissociation.The work provides a new concept to achieve on-demand functions for hydrogen evolution catalysis and beyond,by regulating the interfacial orbital coupling. | Yishang Wu Yufang Xie Shuwen Niu Yipeng Zang Jinyan Cai Zenan Bian Xuanwei Yin Yanyan Fang Da Sun Di Niu Zheng Lu Amirabbas Mosallanezhad Huijuan Wang Dewei Rao Hongge Pan Gongming Wang | 2021 | Nano Research2021，14，10： | 1 |
| 15 | A novel mutation in ROR2 led to the loss of function of ROR2 and inhibited the osteogenic differentiation capability of bone marrow mesenchymal stem cells(BMSCs)显示文摘Receptor tyrosine kinase-like orphan receptor 2(ROR2)has a vital role in osteogenesis.However,the mechanism underlying the regulation of ROR2 in osteogenic differentiation is still poorly comprehended.A previous study by our research group showed that a novel compound heterozygous ROR2 variation accounted for the autosomal recessive Robinow syndrome(ARRS).This study attempted to explore the impact of the ROR2:c.904C>T variant specifically on the osteogenic differentiation of BMSCs.Methods:Coimmunoprecipitation(CoIP)-western blotting was carried out to identify the interaction between ROR2 and Wnt5a.Double-immunofluorescence staining was used for determining the expressions and co-localization of ROR2 and Wnt5a in bone marrow mesenchymal stem cells(BMSCs).Western blot(WB)analysis and quantitative reverse transcription polymerase chain reaction(RT-qPCR)were conducted to identify the expression levels of ROR2 in the BMSCs transfected with LV-shROR2 or LV-ROR2-c.904C>T.The alkaline phosphatase(ALP)activity was detected,and Alizarin Red S staining was done for evaluating the osteogenic differentiation of BMSCs.RT-qPCR was employed to identify the expression of the sphingomyelin synthase 1(SMS1)mRNA in the BMSCs transfected with LV-shROR2 or LV-ROR2-c.904C>T and the mRNA expression levels of Runt-related transcription factor 2(RUNX2),osteocalcin(OCN),and osteopontin(OPN).WB was performed to confirm the protein expressions of extracellular regulated protein kinases1(ERK),P-ERK,Smad family member1/5/8(Smad1/5/8),P-Smad1/5/8,P-P38,P38,RUNX2,OCN,and OPN in the BMSCs transfected with LV-shROR2/LV-ROR2-c.904C>T and sphingomyelin(SM).Results:The ROR2:c.904C>T mutant altered the subcellular localization of the ROR2 protein,which caused an impaired interaction between ROR2 and Wnt5a.The depletion of ROR2 restricted the osteogenic differentiation capability of BMSCs and downregulated the expression of SMS1.SM treatment could reverse the inhibition of osteoblastic differentiation in ROR2-depleted BMSCs.Conclusion:The findings of this work revealed that the ROR2:c.904C>T variant led to the loss of function of ROR2,which impaired the interaction between ROR2 and Wnt5a and also controlled the osteogenic differentiation capability of BMSCs.Furthermore,SM was revealed to be engaged in the osteoblastic differentiation of BMSCs regulated by ROR2,which renders SM a potential target in the therapy for ARRS. | WENQI CHEN XIAOYANG CHU YANG ZENG YOUSHENG YAN YIPENG WANG DONGLAN SUN DONGLIANG ZHANG JING ZHANG KAI YANG | 2023 | BIOCELL2023，47，7： | 0 |
| 16 | Effects of time-delayed vibration absorber on bandwidth of beam for low broadband vibration suppression显示文摘The effects of time-delayed vibration absorber(TDVA) on the dynamic characteristics of a flexible beam are investigated. First, the vibration suppression effect of a single TDVA on a continuous beam is studied. The first optimization criterion is given,and the results show that the introduction of time-delayed feedback control(TDFC) is beneficial to improving the vibration suppression at the anti-resonance band. When a single TDVA is used, the anti-resonance is located at a specific frequency by the optimum design of TDFC parameters. Then, in order to obtain low-frequency and broad bands for vibration suppression, multiple TDVAs are uniformly distributed on a continuous beam,and the relationship between the dynamic responses and the TDFC parameters is investigated. The obtained relationship shows that the TDVA has a significant regulatory effect on the vibration behavior of the continuous beam. The effects of the number of TDVAs and the nonlinearity on the bandgap variation are discussed. As the multiple TDVAs are applied, according to the different requirements on the location and bandwidth of the effective vibration suppression band, the optimization criteria for the TDFC parameters are given, which provides guidance for the applications of TDVAs in practical projects such as bridge and aerospace. | Xiuting SUN Yipeng QU Feng WANG Jian XU | 2023 | Applied Mathematics and Mechanics(English Edition)2023，44，10： | 0 |
| 17 | Sequentially bridged MXene platelets for strong high‐temperature EM‐IR bi‐stealth sheets显示文摘Combination of flexible multifunctional stealth technology properties such as electromagnetic(EM)and infrared(IR)stealth is crucial to the development of aerospace,military,and electronic fields,but the synthesis technology still has a significant challenge.Herein,we have successfully designed and synthesized highly flexible MXene@cellulose lamellae/borate ion(MXCB)sheets with strong high‐temperature EM‐IR bi‐stealth through sequential bridging of hydrogen and covalent bonds.The resultant MXCB sheets display high conductivity and good mechanical features such as flexibility,stretchability,fatigue resistance,and ultrasonic damage.MXCB sheets have a high tensile strength of 795 MPa.Furthermore,MXCB sheets with different thicknesses indicate exceptional high‐temperature thermal‐camouflage characteristics.This reduces the radiation temperature of the target object(>300°C)to 100°C.The conductivity of MXCB sheet with 3μm thickness is 6108 S/cm and the EM interference(EMI)shielding value is 39.74 dB.The normalized surface‐specific EMI SE absolute shielding effectiveness(SSE/t)is as high as 39312.78 dB·cm2/g,which remained 99.39%even after 10,000 times repeated folding.These multifunctional ultrathin MXCB sheets can be arranged by vacuum‐assisted induction to develop EM‐IR bi‐stealth sheet. | Yushan Yang Kaicong Chen Yipeng Chen Chao Wang Baokang Dang Yingying Li Ming Liu Qingfeng Sun | 2024 | SmartMat2024，5，1： | 0 |
| 18 | A biomimetic-structured wood-derived carbon sponge with highly compressible and biocompatible properties for human-motion detection显示文摘Piezoresistive sensors,as an indispensable part of electronic and intelligent wearable devices,are often hindered by nonrenewable resources(graphene,conventional metal,or silicon).Biomass-derived carbonaceous materials boast many advantages such as their light weight,renewability,and excellent chemical stabilization.However,a major challenge is that the strength and resilience of carbon-based piezoresistive materials still falls short of requirements due to their random microarchitectures which cannot provide sufficiently good stress distribution.Encouraged by the excellent compressible properties and extraordinary strength of the Thalia dealbata stem,we propose a wood biomassderived carbon piezoresistive sensor with an artificial interconnected lamellar structure like the stem itself.By introducing a freezing-induced assembly process,a wood-based,completely delignified,nano-lignocellulose material can be built into a“bridges supported lamellar”type architecture,where subsequent freeze-drying and pyrolysis results in carbon aerogel monoliths.The resultant bioinspired carbon sponge has high compressibility and strength,of the order of two to five times higher than that of conventional metal,carbon,and organic materials.Combined with excellent biocompatible properties and chemical durability,these are useful properties for intelligent wearable devices and human-motion detection. | Yipeng Chen Lintong Hu Caicai Li Baokang Dang Qingfeng Sun Tianyou Zhai Huiqiao Li | 2020 | InfoMat2020，2，6： | 0 |
| 19 | Analyzing Ethereum Smart Contract Vulnerabilities at Scale Based on Inter-Contract Dependency显示文摘Smart contracts running on public blockchains are permissionless and decentralized,attracting both developers and malicious participants.Ethereum,the world’s largest decentralized application platform on which more than 40 million smart contracts are running,is frequently challenged by smart contract vulnerabilities.What’s worse,since the homogeneity of a wide range of smart contracts and the increase in inter-contract dependencies,a vulnerability in a certain smart contract could affect a large number of other contracts in Ethereum.However,little is known about how vulnerable contracts affect other on-chain contracts and which contracts can be affected.Thus,we first present the contract dependency graph(CDG)to perform a vulnerability analysis for Ethereum smart contracts,where CDG characterizes inter-contract dependencies formed by DELEGATECALL-type internal transaction in Ethereum.Then,three generic definitions of security violations against CDG are given for finding respective potential victim contracts affected by different types of vulnerable contracts.Further,we construct the CDG with 195,247 smart contracts active in the latest blocks of the Ethereum and verify the above security violations against CDG by detecting three representative known vulnerabilities.Compared to previous large-scale vulnerability analysis,our analysis scheme marks potential victim contracts that can be affected by different types of vulnerable contracts,and identify their possible risks based on the type of security violation actually occurring.The analysis results show that the proportion of potential victim contracts reaches 14.7%,far more than that of corresponding vulnerable contracts(less than 0.02%)in CDG. | Qiuyun Lyu Chenhao Ma Yanzhao Shen Shaopeng Jiao Yipeng Sun Liqin Hu | 2023 | Computer Modeling in Engineering & Sciences2023，，5： | 0 |
