| 1 | Machine Learning−based Weather Support for the 2022 Winter Olympics显示文摘1.A key support for the 2022 Winter Olympics The XXIV Olympic Winter Games are scheduled to take place from 4 to 22 February 2022,followed by the Paralympic Games from 4 to 13 March,in Beijing and towns in the neighboring Hebei Province,China.Weather plays an extremely important role in the outcome of the games(Chen et al.,2018).It can not only cause a difference between a medal or not,but affect the safety of athletes.Success of the Winter Olympics will greatly depend on weather conditions at the outdoor competition venues,dealing with many weather elements including the snow surface temperature,apparent temperature,gust wind speed,snow,visibility,etc.To ensure that the scheduled games go smoothly,it is imperative to have hourly or even every 10-minutely forecasts as well as updated weather-related risk assessments at the venues for the next 240 hours.So far,the Beijing/Hebei Meteorological Observatory has already started intelligent weather forecasting at 3-km resolution based on the results of numerical weather prediction(NWP)models.However,these experiments have suggested that the current forecasting techniques are incapable of capturing the complex mountain weather variations around some venues.The forecasting capability of NWP is constrained partly by limited knowledge of the local weather mechanisms. | Jiangjiang XIA Haochen LI Yanyan KANG Chen YU Lei JI Lve WU Xiao LOU Guangxiang ZHU Zaiwen Wang Zhongwei YAN Lizhi WANG Jiang ZHU Pingwen ZHANG Min CHEN Yingxin ZHANG Lihao GAO Jiarui HAN | 2020 | Advances in Atmospheric Sciences2020，37，9： | 6 |
| 2 | Residence time distribution of high viscosity fluids falling film flow down outside of industrial-scale vertical wavy wall: Experimental investigation and CFD prediction显示文摘The flow behavior of gravity-driven falling film of non-conductive high viscosity polymer fluids on an industrial-scale vertical wavy wall was investigated in terms of film thickness and residence time distribution by numerical simulation and experiment.Falling film flow of high viscosity fluids was found to be steady on a vertical wavy wall in the presence of the large film thickness.The comparison between numerical simulation and experiment for the film thickness both in crest and trough of wavy wall showed good agreement.The simulation results of average residence time of falling film flow with different viscous fluids were also consistent with the experimental results.This work provides the initial insights of how to evaluate and optimize the falling film flow system of polymer fluid. | Shichang Chen Lihao Zhang Yongjun Wang Xianming Zhang Wenxing Chen | 2019 | Chinese Journal of Chemical Engineering2019，27，7： | 4 |
| 3 | The prior rules of designing Ti_(3)C_(2)T_(x) MXene-based gas sensors显示文摘Working temperature,sensitivity,and selectivity are some of the characteristics of the applied gas sensors.How to design and fabricate an ideal gas sensor working at room temperature is still challenging and attracting lots of interest.Two-dimensional(2D)materials with ultra-thin structure have been demonstrated as a family of ideal candidates to achieve this goal.Among them,Ti_(3)C_(2)T_(x) MXene,a kind of layered sheet synthesized by selectively etching MAX phases materials,shows remarkable potential to be the sensitive materials solely or in a composite.However,their designing rules are still lacking critical thinking from the viewpoint of the intrinsic property of Ti_(3)C_(2)T_(x) MXene based materials.In this article,two critical features,i.e.,the thickness of the sensitive materials,and the scope of the analytes,are elaborated towards Ti_(3)C_(2)T_(x) MXene based gas sensors after characterizing the performance of sensing reducing gases(NH3 and CO)and oxidizing gas(NO2).First,the thinner the Ti_(3)C_(2)T_(x) MXene sensitive layer,the better the sensitivity.Second,the Ti_(3)C_(2)T_(x) MXene based gas sensor is not suitable for strong and moderate oxidation gas due to its ease of oxidation.These two rules are demonstrated,and could be considered with priority both in the future researches and practical applications. | Yingying Jian Danyao Qu Lihao Guo Yujin Zhu Chen Su Huanran Feng Guangjian Zhang Jia Zhang Weiwei Wu Ming-Shui Yao | 2021 | Frontiers of Chemical Science and Engineering2021，15，3： | 3 |
| 4 | An Organic Solvent-Assisted Intercalation and Collection (OAIC) for Ti_(3)C_(2)T_(x) MXene with Controllable Sizes and Improved Yield显示文摘A good method of synthesizing Ti_(3)C_(2)T_(x)(MXene)is critical for ensuring its success in practical applications,e.g.,electromagnetic interference shielding,electrochemical energy storage,catalysis,sensors,and biomedicine.The main concerns focus on the moderation of the approach,yield,and product quality.Herein,a modified approach,organic solvent-assisted intercalation and collection,was developed to prepare Ti_(3)C_(2)T_(x) flakes.The new approach simultaneously solves all the concerns,featuring a low requirement for facility(centrifugation speed<4000 rpm in whole process),gram-level preparation with remarkable yield(46.3%),a good electrical conductivity(8672 S cm^(−1)),an outstanding capacitive performance(352 F g^(−1)),and easy control over the dimension of Ti_(3)C_(2)T_(x) flakes(0.47–4.60μm^(2)).This approach not only gives a superb example for the synthesis of other MXene materials in laboratory,but sheds new light for the future mass production of Ti_(3)C_(2)T_(x) MXene. | Danyao Qu Yingying Jian Lihao Guo Chen Su Ning Tang Xingmao Zhang Wenwen Hu Zheng Wang Zhenhuan Zhao Peng Zhong Peipei Li Tao Du Hossam Haick Weiwei Wu | 2021 | Nano-Micro Letters2021，13，11： | 2 |
| 5 | Distribution patterns of 210Po, 210Pb and the particle export in the Taiwan Strait during the winter显示文摘210Po and 210Pb are increasingly used to constrain particle dynamics in the open oceans,however they are less used in coastal waters.Here,distributions and partitions of 210Po and 210Pb were examined in the Taiwan Strait,as well as their application to quantify particle sinking.Activity concentrations of dissolved 210Po and 210Pb(<0.6μm)ranged from 1.21 to 7.63 dpm/(100 L)and from 1.07 to 6.33 dpm/(100 L),respectively.Activity concentrations of particulate 210Po and 210Pb varied from 1.96 to 36.74 dpm/(100 L)and from 3.11 to 38.06 dpm/(100 L).Overall,particulate 210Po and 210Pb accounted for the majority of the bulk 210Po and 210Pb.210Po either in dissolved or particulate phases showed similar spatial patterns to 210Pb,indicating similar mechanisms for controlling the distributions of 210Po and 210Pb in the Taiwan Strait.The different fractionation coefficients indicated that particles in the Zhemin Coastal Current(ZCC)inclined to absorb 210Po prior to 210Pb while they showed an opposite effect in the Taiwan Warm Current(TWC).Based on the disequilibria between 210Po and 210Pb,the sinking fluxes of total particulate matter(TPM)were estimated to range from–0.22 to 3.84 g/(m2·d),showing an overall comparable spatial distribution to previous reported sediment accumulation rates.However,our sinking fluxes were lower than the sedimentation rates,indicating a sediment resuspension in winter and horizontal transport of particulate matter from the Taiwan Strait to the East China Sea. | Lihao Zhang Weifeng Yang Min Chen Yinian Zhu Zhou Wang Ziming Fang Yusheng Qiu Yanhong | 2020 | Acta Oceanologica Sinica2020，39，2： | 1 |
| 6 | Fabrication of a bio-instructive scaffold conferred with a favorable microenvironment allowing for superior implant osseointegration and accelerated in situ vascularized bone regeneration via type H vessel formation显示文摘The potential translation of bio-inert polymer scaffolds as bone substitutes is limited by the lack of neovascularization upon implantation and subsequently diminished ingrowth of host bone,most likely resulted from the inability to replicate appropriate endogenous crosstalk between cells.Human umbilical vein endothelial cell-derived decellularized extracellular matrix(HdECM),which contains a collection of angiocrine biomolecules,has recently been demonstrated to mediate endothelial cells(ECs)-osteoprogenitors(OPs)crosstalk.We employed the HdECM to create a PCL(polycaprolactone)/fibrin/HdECM(PFE)hybrid scaffold.We hypothesized PFE scaffold could reconstitute a bio-instructive microenvironment that reintroduces the crosstalk,resulting in vascularized bone regeneration.Following implantation in a rat femoral bone defect,the PFE scaffold demonstrated early vascular infiltration and enhanced bone regeneration by microangiography(μ-AG)and micro-computational tomography(μ-CT).Based on the immunofluorescence studies,PFE mediated the endogenous angiogenesis and osteogenesis with a substantial number of type H vessels and osteoprogenitors.In addition,superior osseointegration was observed by a direct host bone-PCL interface,which was likely attributed to the formation of type H vessels.The bio-instructive microenvironment created by our innovative PFE scaffold made possible superior osseointegration and type H vessel-related bone regeneration.It could become an alternative solution of improving the osseointegration of bone substitutes with the help of induced type H vessels,which could compensate for the inherent biological inertness of synthetic polymers. | Yijun He Wenhao Wang Shaozhang Lin Yixi Yang Lizhi Song Yihan Jing Lihao Chen Zaopeng He Wei Li Ao Xiong Kelvin W.K.Yeung Qi Zhao Yuan Jiang Zijie Li Guoxian Pei Zhi-Yong Zhang | 2022 | Bioactive Materials2022，7，3： | 1 |

| 8 | Mediator complex subunit MED25 physically interacts with DST to regulate spikelet number in rice显示文摘Grain number is a flexible trait and contributes significantly to grain yield.In rice,the zinc finger transcription factor DROUGHT AND SALT TOLERANCE(DST)controls grain number by directly regulating cytokinin oxidase!dehydrogenase 2(OsCKX2)expression.Although specific upstream regulators of the DST-OsCKX2 module have been identified,the mechanism employed by DST to regulate the expression of OsCKX2 remains unclear.Here,we demonstrate that DST-interacting protein 1(DIP1),known as Mediator subunit OsMED25,acts as an interacting coactivator of DST.Phenotypic analyses revealed that OsMED25-RNAi and the osmed25 mutant plants exhibited enlarged panicles,with enhanced branching and spikelet number,similar to the dst mutant.Genetic analysis indicated that OsMED25 acts in the same pathway as the DST-OsCKX2 module to regulate spikelet number per panicle.Further biochemical analysis showed that OsMED25 physically interacts with DST at the promoter region of OsCKX2,and then recruits RNA polymerase II(Pol II)to activate OsCKX2 transcription.Thus,OsMED25 was involved in the communication between DST and Pol II general transcriptional machinery to regulate spikelet number.In general,our findings reveal a novel function of OsMED25 in DST-OsCKX2 modulated transcriptional regulation,thus enhancing our un derstanding of the regulatory mechanism underlying DST-OsCKX2-mediated spikelet number. | Lihao Lin Minmin Du Shuyu Li Chuanlong Sun Fangming Wu Lei Deng Qian Chen Chuanyou Li | 2022 | Journal of Integrative Plant Biology2022，64，4： | 1 |
| 9 | Fertilization and clear-cutting effects on greenhouse gas emissions of pinewood nematode damaged Masson pine plantation显示文摘Introduction:Management practices are essential for maintaining forest ecological functions under increasing diseases and pest disasters.The effects of nitrogen fertilization(NF)and clear-cutting(CC)on the soil microbial community structure and greenhouse gases emission were investigated of pinewood nematodes(Bursaphelenchus xylophilus)-infected Masson pine(Pinus massoniana)plantations.Outcomes:CC increased the soil microbial biomass carbon(SMBC)and soil microbial biomass nitrogen(SMBN)contents relative to the control(CK).NF increased the SMBN but had no significant effect on the SMBC content.The total fungal and bacterial abundances increased in the CC treatment compared with the CK,but there was no significant difference between the NF and CK.The cumulative soil CO_(2)emission(-2.35 t C·hm^(-2))was higher than that of CK(1.65 t C·hm^(-2))in summer,and the cumulative annual N_(2)O emission(16.90 kg N·hm^(-2)yr^(-1))of NF was approximately 47 times of CK(0.36 t N·hm^(-2)·yr^(-1)).CC increased the CO_(2)flux(-2.21 t C·hm^(-2))in summer but have no significantly effects on N_(2)O emission.Conclusion:These results indicated that NF and CC practices changed forest soil microbial community structure and affected soil greenhouse gas emissions in pinewood nematodes-infected Masson pine plantations.The CO_(2)emission rates increased in the NF and CC treatments,which reduced the carbon sequestration function of forests and had a negative impact on climate change. | Xue Zhang Zeyao Zhao Tong Chen Tianyu Zhao Lihao Song Li Mei | 2021 | Ecosystem Health and Sustainability2021，7，1： | 1 |
| 10 | SEMG-based fighter pilot muscle fatigue analysis and operation performance research显示文摘Fatigue has a tremendously adverse impact on pilot performance.This study aims to explore the Biceps Brachii(BB),Rectus Femoris(RF),Flexor Carpi Radialis(FCR),and Tibialis Anterior(TA)activities of fighter pilots in the early and late combat stages,and the target hitting time.A total of 13 volunteers were recruited to conduct simulated combats inside a real fighter cockpit.The surface Electromyography(sEMG)was collected from all volunteers in the initial and final 20s of flight,and the target hitting time during three simulated combats was recorded.The root mean square(RMS)values of right BB and TA were significantly higher than the left side values(p<0.001),while insignificant differences were found in the RMS values between the bilateral RF and FCR.Compared to the early flight period,the median frequency(MF)values of BB and TA were significantly lower during the late flight period,and the RMS values were significantly higher(p<0.047).Contrastively,the RMS values of FCR and RF differed insignificantly during the late flight period.Regarding the target hitting time,a significant difference was noted between task 1 and rask3.Subjects exhibit varying levels of muscle fatigue for different muscle groups before and after the flight.The muscle fatigue levels are asymmetrical on the left and right sides.Muscle fatigue might reduce the pilots'operational ability.This study provides a reference for fighter pilot fatigue protection and treatment. | Biyun Zhou Bo Chen Huijuan Shi Lihao Xue Yingfang Ao Li Ding | 2022 | Medicine in Novel Technology and Devices2022，，4： | 0 |
| 11 | Metabolic engineering of Streptomyces to enhance the synthesis of valuable natural products显示文摘The mycelial bacterium Streptomyces is a workhorse for producing natural products,serving as a key source of drugs and other valuable chemicals.However,its complicated life cycle,silent biosynthetic gene clusters(BGCs),and poorly characterized metabolic mechanisms limit efficient production of natural products.There-fore,a metabolic engineering strategy,including traditional and emerging tools from different disciplines,was developed to further enhance natural product synthesis by Streptomyces.Here,current trends in systems metabolic engineering,including tools and strategies,are reviewed.Particularly,this review focuses on recent developments in the selection of methods for regulating the Streptomyces life cycle,strategies for the activation of silent gene clusters,and the exploration of regulatory mechanisms governing antibiotic production.Finally,future challenges and prospects are discussed. | Zuwei Xu Lihao Ji Wenxiu Tang Liang Guo Cong Gao Xiulai Chen Jia Liu Guipeng Hu Liming Liu | 2022 | Engineering Microbiology2022，2，2： | 0 |
| 12 | Multimodal critical-scenarios search method for test of autonomous vehicles显示文摘Purpose–The purpose of this paper is to search for the critical-scenarios of autonomous vehicles(AVs)quickly and comprehensively,which is essential for verification and validation(V&V).Design/methodology/approach–The author adopted the index F1 to quantitative critical-scenarios’coverage of the search space and proposed the improved particle swarm optimization(IPSO)to enhance exploration ability for higher coverage.Compared with the particle swarm optimization(PSO),there were three improvements.In the initial phase,the Latin hypercube sampling method was introduced for a uniform distribution of particles.In the iteration phase,the neighborhood operator was adapted to explore more modals with the particles divided into groups.In the convergence phase,the convergence judgment and restart strategy were used to explore the search space by avoiding local convergence.Compared with the Monte Carlo method(MC)and PSO,experiments on the artificial function and critical-scenarios search were carried out to verify the efficiency and the application effect of the method.Findings–Results show that IPSO can search for multimodal critical-scenarios comprehensively,with a stricter threshold and fewer samples in the experiment on critical-scenario search,the coverage of IPSO is 14%higher than PSO and 40%higher than MC.Originality/value–The critical-scenarios’coverage of the search space is firstly quantified by the index F1,and the proposed method has higher search efficiency and coverage for the critical-scenarios search of AVs,which shows application potential for V&V. | Tianyue Feng Lihao Liu Xingyu Xing Junyi Chen | 2022 | Journal of Intelligent and Connected Vehicles2022，5，3： | 0 |
| 13 | Trace Elements of Multi-stage Minerals and Titanite U-Pb Dating for the Gneisses from Liansan Island,Sulu UHPM Belt显示文摘Gneisses with anatectic characteristics from the Liansan island in the Sulu UHPM(ultra-high pressure metamorphic)belt were studied for petrography,titanite U-Pb dating and mineral geochemistry.Three origins of garnets are distinguished:metamorphic garnet,peritectic garnet and anatectic garnet,which are formed in the stages of peak metamorphism,retrograde anatexis and melt crystallization,respectively.The euhedral titanite has a high content of REE and high Th/U ratios,which is interpreted as indicating that it was newly-formed from an anatectic melt.The LA-ICP-MS titanite U-Pb dating yields 214-217 Ma ages for the titanite(melt)crystallization.The distribution of trace elements varies in response to the different host minerals at different stages.At the peak metamorphic stage,Y and HREE are mainly hosted by garnet,Ba and Rb by phengite,Sr,Nb,Ta,Pb,Th,U and LREE by allanite and Y,U and HREE by zircon.During partial melting,Y,Pb,Th,U and REE are released into the melt,which causes a dramatic decline of these element contents in the retrograde minerals.Finally,titanite absorbs most of the Nb,U,LREE and HREE from the melt.Therefore,the different stages of metamorphism have different mineral assemblages,which host different trace elements. | SONG Lihao CAO Yuting XIE Tianhe CHEN Yuyao GAO Yuan WANG Songjie LI Xuping | 2023 | Acta Geologica Sinica(English Edition)2023，97，6： | 0 |
| 14 | Antioxidant-enriched autologous biogel promoted diabetic wound healing by remodeling inherent posttraumatic inflammatory patterning and restoring compromised microenvironment homeostasis显示文摘Successful wound healing depends on the reconstruction of proper tissue homeostasis,particularly in the posttraumatic inflammatory tissue microenvironment.Diabetes jeopardizes tissues’immune homeostasis in cutaneous wounds,causing persistent chronic inflammation and cytokine dysfunction.Previously,we developed an autologous regeneration factor(ARF)technology to extract the cytokine composite from autologous tissue to restore immune homeostasis and promote wound healing.However,treatment efficacy was significantly compromised in diabetic conditions.Therefore,we proposed that a combination of melatonin and ARF,which is beneficial for proper immune homeostasis reconstruction,could be an effective treatment for diabetic wounds.Our research showed that the utilization of melatonin-mediated ARF biogel(AM gel)promoted diabetic wound regeneration at a more rapid healing rate.RNA-Seq analysis showed that AM gel treatment could restore more favorable immune tissue homeostasis with unique inflammatory patterning as a result of the diminished intensity of acute and chronic inflammation.Currently,AM gel could be a novel and promising therapeutic strategy for diabetic wounds in clinical practice through favorable immune homeostatic reconstructions in the tissue microenvironment and proper posttraumatic inflammation patterning. | Yixi Yang Le Wang Yonglin Zhou Yijun He Shaozhang Lin Yuwei Zeng Yunhe Zhou Wei Li Zaopeng He Qi Zhao Lihao Chen Zijie Li Wenhao Wang Zhi-Yong Zhang | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
| 15 | Multi-dimensional characteristic construction methods of computational materials under big data environment显示文摘Characteristic construction is an important part of material data analysis.In the big data environment,the de-velopment of material data science will have implications for multidimensional data analysis methods.Among these,the machine learning method for multidimensional data models can be widely applied to material data types,including element ratios,atomic compositions,electronic arrangements,molecular structures,and energy distributions.For high-throughput computing materials,it is recommended in material data science to judge and extract the main characteristics influencing material properties and predict novel functional materials us-ing the discovered laws.Consequently,we considere the characteristic construction,learning prediction,feature extraction,and high-order analysis of computational materials as the main research purposes,and construct a composite analysis model of the material system by combining data preprocessing,data mining,data evaluation,and knowledge representation as the main steps of data analysis.This demonstrates that a method to comprehen-sively judge the properties of materials by constructing the characteristics of materials in different dimensions is essential. | Lihao Chen Shuopu Wang Chen Zou Ben Xu Ke Bi | 2022 | ChemPhysMater2022，1，3： | 0 |
| 16 | Cadmium removal mechanistic comparison of three Fe-based nanomaterials: Water-chemistry and roles of Fe dissolution显示文摘Cadmium(Cd)is a common toxic heavy metal in the environment.Taking Cd(II)as a target contaminant,we systematically compared the performances of three Fe-based nanomaterials(nano zero valent iron,nZVI;sulfidated nZVI,S-nZVI;and nano FeS,nFeS)for Cd immobilization under anaerobic conditions.Effects of nanomaterials doses,initial pH,co-existing ions,and humic acid(HA)were examined.Under identical conditions,at varied doses or initial pH,Cd(II)removal by three materials followed the order of S-nZVI>nFeS>nZVI.At pH 6,the Cd(II)removal within 24 hours for S-nZVI,nFeS,and nZVI(dose of 20 mg/L)were 93.50%,89.12%and 4.10%,respectively.The fast initial reaction rate of nZVI did not lead to a high removal capacity.The Cd removal was slightly impacted or even improved with co-existing ions(at 50 mg/L or 200 mg/L)or HA(at 2 mg/L or 20 mg/L).Characterization results revealed that nZVI immobilized Cd through coprecipitation,surface complexation,and reduction,whereas the mechanisms for sulfidated materials involved replacement,coprecipitation,and surface complexation,with replacement as the predominant reaction.A strong linear correlation between Cd(II)removal and Fe(II)dissolution was observed,and we proposed a novel pseudo-second-order kinetic model to simulate Fe(II)dissolution. | Xiaoge Huang Lihao Chen Ziqi Ma Kenneth C.Carroll Xiao Zhao Zailin Huo | 2022 | Frontiers of Environmental Science & Engineering2022，16，12： | 0 |
| 17 | Pepper variome reveals the history and key loci associated with fruit domestication and diversification显示文摘Pepper(Capsicum spp.)is an important vegetable crop that provides a unique pungent sensation when eaten.Through construction of a pepper variome map,we examined the main groups that emerged during domestication and breeding of C.annuum,their relationships and temporal succession,and the molecular events underlying the main transitions.The results showed that the initial differentiation in fruit shape and pungency,increase in fruit weight,and transition from erect to pendent fruits,as well as the recent appearance of large,blocky,sweet fruits(bell peppers),were accompanied by strong selection/fixation of key alleles and introgressions in two large genomic regions.Furthermore,we identified Up,which encodes a BIG GRAIN protein involved in auxin transport,as a key domestication gene that controls erect vs pendent fruit orientation.The up mutation gained increased expression especially in the fruit pedicel through a 579-bp sequence deletion in its 5′upstream region,resulting in the phenotype of pendent fruit.The function of Up was confirmed by virus-induced gene silencing.Taken together,these findings constitute a cornerstone for understanding the domestication and differentiation of a key horticultural crop. | Yacong Cao Kang Zhang Hailong Yu Shumin Chen Donghui Xu Hong Zhao Zhenghai Zhang Yinqing Yang Xiaozhen Gu Xinyan Liu Haiping Wang Yaxin Jing Yajie Mei Xiang Wang Véronique Lefebvre Weili Zhang Yuan Jin Dongliang An Risheng Wang Paul Bosland Xixiang Li IIan Paran Baoxi Zhang Giovanni Giuliano Lihao Wang Feng Cheng | 2022 | Molecular Plant2022，15，11： | 0 |
| 18 | ScY@C_(3v)(8)-C_(82):Metal-Metalσ^(2)Bond in Mixed Rare-Earth Di-metallofullerenes显示文摘Comprehensive Summary The experimental investigation of rare-earth metal-metal bonds remains a challenge in the study of chemical bonds.Herein,we report the synthesis and characterization of a novel heteronuclear di-metallofullerene,ScY@C_(3v)(8)-C_(82),which contains a mixed rare-earth metal-metal bond.ScY@C_(3v)(8)-C_(82)was successfully synthesized by arc-discharging method and characterized by mass spectrometry,UV-vis-NIR spectroscopy and single-crystal X-ray diffraction crystallography,which unambiguously determined its molecular structure.Theoretical calculations were also performed to study the optimized positions of Sc-Y metallic dimer and the electronic configuration.The combined experimental and theoretical results confirmed that both Sc and Y atoms transfer two electrons to the C_(3v)(8)-C_(82)cage,i.e.,(ScY)4+@(C_(3v)(8)-C_(82))4-.In particular,a covalent Sc-Yσ2 bond,which has never been reported before,is proven to be formed inside C_(3v)(8)-C_(82)fullerene cage.This work presents a novel di-metallofullerene containing mixed rare-earth metal-metal bond and expands the understanding of metal-metal bonding of rare earth elements. | Lihao Zheng Yannick Roselló Yingjing Yan Yang-Rong Yao Xiaolin Fan Josep M.Poblet Antonio Rodríguez-Fortea Ning Chen | 2023 | Chinese Journal of Chemistry2023，41，15： | 0 |

| 20 | Review on the terahertz metasensor:from featureless refractive index sensing to molecular identification显示文摘The terahertz(THz)wave is at the intersection between photonics and electronics in the electromagnetic spectrum.Since the vibration mode of many biomedical molecules and the weak interaction mode inside the molecules fall in the THz regime,utilizing THz radiation as a signal source to operate substance information sensing has its unique advantages.Recently,the metamaterial sensor(metasensor)has greatly enhanced the interaction between signal and substances and spectral selectivity on the subwavelength scale.However,most past review articles have demonstrated the THz metasensor in terms of their structures,applications,or materials.Until recently,with the rapid development of metasensing technologies,the molecular information has paid much more attention to the platform of THz metasensors.In this review,we comprehensively introduce the THz metasensor for detecting not only the featureless refractive index but also the vibrational/chiral molecular information of analytes.The objectives of this review are to improve metasensing specificity either by chemical material-assisted analyte capture or by physical molecular information.Later,to boost THz absorption features in a certain frequency,the resonant responses of metasensors can be tuned to the molecular vibrational modes of target molecules,while frequency multiplexing techniques are reviewed to enhance broadband THz spectroscopic fingerprints.The chiral metasensors are also summarized to specific identification chiral molecules.Finally,the potential prospects of next generation THz metasensors are discussed.Compared to featureless refractive index metasensing,the specific metasensor platforms accelerated by material modification and molecular information will lead to greater impact in the advancement of trace detection of conformational dynamics of biomolecules in practical applications. | JIAMING LYU LIHAO HUANG LIN CHEN YIMING ZHU SONGLIN ZHUANG | 2024 | Photonics Research2024，12，2： | 0 |
