| 1 | Coordinated optimal dispatch and market equilibrium of integrated electric power and natural gas networks with P2G embedded显示文摘As power to gas(P2 G) technology gradually matures, the coupling between electricity networks and natural gas networks should ideally evolve synergistically.With the intent of characterizing market behaviors of integrated electric power and natural gas networks(IPGNs)with P2 G facilities, this paper establishes a steady-state model of P2 G and constructs optimal dispatch models of an electricity network and a natural gas network separately. In addition, a concept of slack energy flow(SEF) is proposed as a tool for coordinated optimal dispatch between the two networks. To study how the market pricing mechanism affects coordinated optimal dispatch in an IPGN, a market equilibrium-solving model for an IPGN is constructed according to game theory, with a solution based on the Nikaido-Isoda function. Case studies are conducted on a joint model that combines the modified IEEE 118-node electricity network and the Belgian 20-node gas network.The results show that if the game between an electric power company and a natural gas company reaches market equilibrium, not only can both companies maximize their profits, but also the coordinated operation of the coupling units, i.e., gas turbines and P2 G facilities, will contribute more to renewable energy utilization and carbon emission reduction. | Zexing CHEN Yongjun ZHANG Tianyao JI Zexiang CAI Licheng LI Zhiheng XU | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，3： | 37 |
| 2 | Immune secondary response and clonal selection inspired optimizers显示文摘The immune system's ability to adapt its B cells to new types of antigen is powered by processes known as clonal selection and affinity maturation. When the body is exposed to the same antigen,immune system usually calls for a more rapid and larger response to the antigen,where B cells have the function of negative adjustment. Based on the clonal selection theory and the dynamic process of immune response,two novel artificial immune system algorithms,secondary response clonal programming algorithm (SRCPA) and secondary response clonal multi-objective algorithm (SRCMOA),are presented for solving single and multi-objective optimization problems,respectively. Clonal selection operator (CSO) and secondary response operator (SRO) are the main operators of SRCPA and SRCMOA. Inspired by the clonal selection theory,CSO reproduces individuals and selects their improved maturated progenies after the affinity mat-uration process. SRO copies certain antibodies to a secondary pool,whose members do not participate in CSO,but these antibodies could be activated by some external stimulations. The update of the secondary pool pays more attention to maintain the population diversity. On the one hand,decimal-string representation makes SRCPA more suitable for solving high-dimensional function optimiza-tion problems. Special mutation and recombination methods are adopted in SRCPA to simulate the somatic mutation and receptor edit-ing process. Compared with some existing evolutionary algorithms,such as OGA/Q,IEA,IMCPA,BGA and AEA,SRCPA is shown to be able to solve complex optimization problems,such as high-dimensional function optimizations,with better performance. On the other hand,SRCMOA combines the Pareto-strength based fitness assignment strategy,CSO and SRO to solve multi-objective optimization problems. The performance comparison between SRCMOA,NSGA-Ⅱ,SPEA,and PAES based on eight well-known test problems shows that SRCMOA has better performance in converging to approximate Pareto-optimal fronts with wide distributions. | Maoguo Gong Licheng Jiao Lining Zhang Haifeng Du | 2009 | Progress in Natural Science:Materials International2009，19，2： | 24 |
| 3 | The Impact of the Linked Factors of Provenance,Tectonics and Climate on Potash Formation:An Example from the Potash Deposits of Lop Nur Depression in Tarim Basin,Xinjiang,Western China显示文摘Potash deposits commonly accumulate in highly restricted settings at the final stage of brine evaporation. This does not mean that potash deposits are formed simply as a result of the evaporation concentration of seawater or lake water, but rather as a coupling result of particular provenance, tectonics and climate activities. In this paper, we focus on the formative mechanism of the potash deposits of Lop Nur depression in Tarim Basin to interpret the detailed coupling mechanism among provenance, tectonics and climate. In terms of the provenance of Lop Nur Lake, the water of the Tarim River which displays 'potassium-rich' characteristics play an important role. In addition, the Pliocene and Lower-Middle Pleistocene clastic beds surrounding Lop Nur Lake host a certain amount of soluble potassium and thus serves as 'source beds' for potash formation. During the late Pliocene, the Lop Nur region has declined and evolved into a great lake from the previous piedmont and diluvial fan area. Since the mid Pleistocene, the great-united Lop Nur Lake has been separated and has generated a chain system consisting of Taitema Lake, Big Ear Lake and Luobei Lake which has turned into the deepest sag in Lop Nur Lake. Dry climate in Lop Nur region has increased since the Pliocene, and became extreme at the late Pleistocene. The study implies that potash formation in Lop Nur Lake depends on the optimal combination of extreme components of provenance, tectonics and climate during a shorter-term period. The optimal patterns of three factors are generally characterized by the long-term accumulation and preliminary enrichment of potassium, the occurrence of the deepest sub-depression and the appearance of an extremely arid climate in Lop Nur region. These factors have been interacting synergistically since the forming of the saline lake and in the later stages strong 'vapor extraction' caused by extremely arid climate is needed to trigger large scale mineralization of potash deposits. | LIU Chenglin JIAO Pengcheng Lü Fenglin WANG Yongzhi SUN Xiaohong ZHANG Hua WANG Licheng YAO Fojun | 2015 | Acta Geologica Sinica(English Edition)2015，89，6： | 18 |
| 4 | Seasonal and spatial distributions of euphotic zone and longterm variations in water transparency in a clear oligotrophic Lake Fuxian, China显示文摘To assess the seasonal and spatial variations and long-term trends in water optical properties in Lake Fuxian, investigations based on field work in four seasons and a long-term analysis of data from 1980 to 2014 were conducted. The results show that there was no significant variation in the euphotic depth(Z_(eu)) across the four seasons, and no significant correlations between Z_(eu) and potential influencing factors in seasons other than summer, suggesting that the water itself may be a major factor regulating the Z_(eu)in general. Nevertheless, significant differences in Z_(eu) between the north region(NR) and the south region(SR) were observed in all seasonal tests except spring. This finding relates to a higher abundance of chromophoric dissolved organic matter(CDOM) in the NR due to runoff, especially in the rainy seasons(summer and autumn).CDOM and its terrigenous component had an important impact on Z_(eu)in summer, with the highest precipitation, and impacts from suspended solids and non-algal particles were also found in the NR in summer. The Secchi disk depth in the lake decreased clearly over the years,with significantly negative correlations with the increasing permanganate index and air temperature, implying that organic contaminants(CDOM and/or phytoplankton) are important regulators of water transparency. We estimate that the combined effects of climate warming and changes in land use and land cover are also indirect regulating factors. These findings should be considered in the protection of Lake Fuxian, owing to the importance of light penetration in aquatic ecosystems. | Qichao Zhou Yunlin Zhang Kaidi Li Licheng Huang Fengle Yang Yuanyang Zhou Junjun Chang | 2018 | Journal of Environmental Sciences2018，30，10： | 18 |
| 5 | Global correlation for strontium isotope curve in the Late Cretaceous of Tibet and dating marine sediments显示文摘87Sr/86Sr ratios of marine carbonate samples collected from a sedimentary section of the Late Cretaceous in the south of Tibet were measured. Based on the absence of cathodoluminescence and a very low Mn/Sr ratio (average 0.06) of the samples, it is thought that they contain information on the original seawater strontium isotope composition. The strontium isotope evolution curve of the Late Cretaceous in Tibet we established here, is consistent with other coeval curves from Europe, North America and Antarctica, supports the notion that the strontium isotope composition of seawater is governed by global events, which provides a new approach for the inter-continental and inter-basinal correlations of Late Cretaceous in the area and is a complementarity for biostratigraphy. In addition, we attempt to determine the age of the boundaries for Campanian/Santonian and Maastrichtian/Campanian by 87Sr/86Sr ratios for Gamba section in southern Tibet. The two boundaries are located in the thickness of 217 m (83.5 Ma) and 291 m (71.3 Ma), respectively. | HUANG Sijing SHI He SHEN Licheng ZHANG Meng WU Wenhui | 2005 | Science China Earth Sciences2005，48，2： | 11 |
| 6 | Bench-to-bedside strategies for osteoporotic fracture: from osteoimmunology to mechanosensation显示文摘Osteoporosis is characterized by a decrease in bone mass and strength, rendering people prone to osteoporotic fractures caused by low-energy forces. The primary treatment strategy for osteoporotic fractures is surgery;however, the compromised and comminuted bones in osteoporotic fracture sites are not conducive to optimum reduction and rigid fixation. In addition, these patients always exhibit accompanying aging-related disorders, including high inflammatory status, decreased mechanical loading and abnormal skeletal metabolism, which are disadvantages for fracture healing around sites that have undergone orthopedic procedures. Since the incidence of osteoporosis is expected to increase worldwide, orthopedic surgeons should pay more attention to comprehensive strategies for improving the poor prognosis of osteoporotic fractures. Herein, we highlight the molecular basis of osteoimmunology and bone mechanosensation in different healing phases of elderly osteoporotic fractures, guiding perioperative management to alleviate the unfavorable effects of insufficient mechanical loading, high inflammatory levels and pathogen infection. The well-informed pharmacologic and surgical intervention, including treatment with anti-inflammatory drugs and sufficient application of antibiotics, as well as bench-to-bedside strategies for bone augmentation and hardware selection, should be made according to a comprehensive understanding of bone biomechanical properties in addition to the remodeling status of osteoporotic bones, which is necessary for creating proper biological and mechanical environments for bone union and remodeling. Multidisciplinary collaboration will facilitate the improvement of overall osteoporotic care and reduction of secondary fracture incidence. | Yong Xie Licheng Zhang Qi Xiong Yanpan Gao Wei Ge Peifu Tang | 2019 | Bone Research2019，7，3： | 10 |
| 7 | New insights on the origin of the basement of the Xisha Uplift,South China Sea显示文摘The study of basement geochronology provides crucial insights into the tectonic evolution of oceans. However, early studies on the basement of the Xisha Uplift were constrained by limited geophysical and seismic data; Xiyong1 was the only commercial borehole drilled during the 1970 s because of the huge thickness of overlying Cenozoic strata on the continental margin. Utilizing two newly-acquired basement samples from borehole XK1, we present petrological analysis and zircon uranium(U)-lead(Pb) isotope dating data in this paper that enhance our understanding of the formation and tectonic features of the Xisha Uplift basement. Results indicate that this basement is composed of Late Jurassic amphibole plagiogneisses that have an average zircon 206 Pb/238 U age of 152.9±1.7 Ma. However, the youngest age of these rocks, 137±1 Ma, also suggests that metamorphism termination within the Xisha basement occurred by the Early Cretaceous. These metamorphic rocks have adamellites underneath them which were formed by magmatic intrusions during the late stage of the Early Cretaceous(107.8±3.6 Ma). Thus, in contrast to the Precambrian age(bulk rubidium(Rb)-strontium(Sr) analysis, 627 Ma) suggested by previous work on the nearby Xiyong1 borehole, zircons from XK1 are likely the product of Late Mesozoic igneous activity. Late Jurassic-Early Cretaceous regional metamorphism and granitic intrusions are not confined to Xisha; rocks have also been documented from areas including the Pearl River Mouth Basin and the Nansha Islands(Spratly Islands) and thus are likely closely related to large-scale and long-lasting subduction of the paleo-Pacific plate underneath the continental margins of East Asia, perhaps the result of closure of the Meso-Tethys in the South China Sea(SCS). Controversies remain as to whether, or not, the SCS region developed initially on a uniform Precambrian-aged metamorphic crystalline basement. It is clear, however, that by this time both Mesozoic compressive subduction and Cenozoic rifting and extension had significantly modified the original basement of the SCS region. | ZHU WeiLin XIE XiNong WANG ZhenFeng ZHANG DaoJun ZHANG ChengLi CAO LiCheng SHAO Lei | 2017 | Science China Earth Sciences2017，60，12： | 10 |
| 8 | Heterogeneous parallel computing accelerated iterative subpixel digital image correlation显示文摘Parallel computing techniques have been introduced into digital image correlation(DIC) in recent years and leads to a surge in computation speed. The graphics processing unit(GPU)-based parallel computing demonstrated a surprising effect on accelerating the iterative subpixel DIC, compared with CPU-based parallel computing. In this paper, the performances of the two kinds of parallel computing techniques are compared for the previously proposed path-independent DIC method, in which the initial guess for the inverse compositional Gauss-Newton(IC-GN) algorithm at each point of interest(POI) is estimated through the fast Fourier transform-based cross-correlation(FFT-CC) algorithm. Based on the performance evaluation, a heterogeneous parallel computing(HPC) model is proposed with hybrid mode of parallelisms in order to combine the computing power of GPU and multicore CPU. A scheme of trial computation test is developed to optimize the configuration of the HPC model on a specific computer. The proposed HPC model shows excellent performance on a middle-end desktop computer for real-time subpixel DIC with high resolution of more than 10000 POIs per frame. | HUANG JianWen ZHANG LingQi JIANG ZhenYu DONG ShouBin CHEN Wei LIU YiPing LIU ZeJia ZHOU LiCheng TANG LiQun | 2018 | Science China(Technological Sciences)2018，61，1： | 9 |
| 9 | Synthesis of Bimodal Mesoporous TiO_(2)-PTA/BMMS and Its Enhanced Performance in the Photocatalytic Oxidative Desulfurization显示文摘With the bimodal mesoporous silica(BMMS)acting as the support and the composite of TiO2 with phosphotungstic acid(PTA)functioning as the active constituent,TiO_(2)-PTA/BMMS was synthesized by the two-step impregnation route.This catalyst was applied in the photocatalytic oxidative desulfurization(PODS)process,with dibenzothiophene serving as the model sulfur compound.PODS proceeds in one pot,in which H_(2)O_(2) acts as the oxidant and methanol plays the role of the solvent.TiO_(2)-PTA/BMMS was characterized by XRD,N_(2) adsorption and desorption,XRF,FTIR,UV-vis,SEM,EDS and TEM techniques.It showed that the introduction of PTA contributes higher order,higher surface area and pore volume to the bimodal mesoporous support.With TiO_(2)-PTA/BMMS used as the catalyst under the UV irradiation,the desulfurization rate can reach 99.6%.This result is obviously higher than that achieved by TiO_(2)/BMMS.The catalyst also has no significant drop in catalytic activity after eight runs of reusing.In such catalytic system,the synergistic effects of this photocatalytic oxidation and the extraction with the methanol serving as the solvent played an indispensable role. | Yang Lina Zhang Xi Cui Licheng Xu Meizhen Li Jian | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，3： | 8 |
| 10 | The Toxic Mechanism of High Lethality of Herbicide Butachlor in Marine Flatfish Flounder,Paralichthys olivaceus显示文摘The toxic mechanism of herbicide butachlor to induce extremely high lethality in marine flatfish flounder,Paralichthys Olivaceus,was analyzed by histopathological examination,antioxidant enzymes activities and ATP content assay.Histopathological examination of gill,liver and kidney of exposed fishes showed that gill was a target organ of butachlor.The butachlor seriously impaired the respiration of gills by a series of lesions such as edema,lifting and detachment of lamellar epithelium,breakdown of pillar cells,and blood congestion.The dysfunction of gill respiration caused suffocation to the exposed flounder with extremely high acute lethality.Antioxidant enzyme activity assay of the in vitro cultured flounder gill(FG) cells exposed to butachlor indicated that butachlor markedly inhibited the antioxidant enzyme activities of Superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GPX).Furthermore,along with the decline of antioxidant enzyme activities,ATP content in the exposed FG cells decreased,too.This infers that the oxidative stress induced by butachlor can inhibit the production of cellular ATP.Similar decrease of ATP content was also observed in the exposed flounder gill tissues.Taken together,as in FG cells,butachlor possibly induced a short supply of ATP in pillar cells by inhibiting the antioxidant enzyme activities and then affecting the contractibility of the pillar cells,which in turn resulted in the blood congestion and suffocation of exposed flounder. | GUO Huarong YIN Licheng ZHANG Shicui FENG Wenrong | 2010 | Journal of Ocean University of China2010，9，3： | 8 |
| 11 | Skeleton-vasculature chain reaction: a novel insight into the mystery of homeostasis显示文摘Angiogenesis and osteogenesis are coupled.However,the cellular and molecular regulation of these processes remains to be further investigated.Both tissues have recently been recognized as endocrine organs,which has stimulated research interest in the screening and functional identification of novel paracrine factors from both tissues.This review aims to elaborate on the novelty and significance of endocrine regulatory loops between bone and the vasculature.In addition,research progress related to the bone vasculature,vessel-related skeletal diseases,pathological conditions,and angiogenesis-targeted therapeutic strategies are also summarized.With respect to future perspectives,new techniques such as single-cell sequencing,which can be used to show the cellular diversity and plasticity of both tissues,are facilitating progress in this field.Moreover,extracellular vesicle-mediated nuclear acid communication deserves further investigation.In conclusion,a deeper understanding of the cellular and molecular regulation of angiogenesis and osteogenesis coupling may offer an opportunity to identify new therapeutic targets. | Ming Chen Yi Li Xiang Huang Ya Gu Shang Li Pengbin Yin Licheng Zhang Peifu Tang | 2021 | Bone Research2021，9，3： | 6 |
| 12 | Integrated energy storage system based on triboelectric nanogenerator in electronic devices显示文摘The emergence of electronic devices has brought earth-shaking changes to people's life.However,an extemal power source may become indispensable to the electronie devices due to the limited capacity of batteries.As one of the possible solutions for the extermal power sources,the triboelectric nanogenerator(TENG)provides a novel idea to the increasing mumber of personal electronic devices.TENG is a new type of energy ollector,which has become a hot spot in the field of nanotechnology.It is widely used at the acquisition and conversion of mechan-ical enegy to electrice energy through the principle of electrostatic induction.On this basis,the TENG could be integrated with the energy stonage system into a self-powered system,W hich can supply power to the electronic devices and make them work continuously.In this review,TENG's basic structure as well as its working process and working mode are firstly discussed.The integration method of TENGs with enegy storage systems and the related research status are then introduced in detail.At the end of this paper,we put forward some problems and discuss the prospect in the future. | Xiao Feng Yang Zhang Le Kang Licheng Wang Chongxiong Duan Kai Yin Jinbo Pang Kai Wang | 2021 | Frontiers of Chemical Science and Engineering2021，15，2： | 5 |
| 13 | A mini-review on the modeling of volatile organic compound adsorption in activated carbons: Equilibrium, dynamics, and heat effects显示文摘The research on the adsorption equilibria,kinetics,and increase in process temperature of the volatile organic compound(VOC)adsorption in porous materials ensures safe production,thereby reducing production costs and improving separation efficiency.Therefore,it is critical in predicting the entire adsorption process based on minimal or no experimental input of the adsorbate and adsorbent.We discuss,in this review,the factors that affect the adsorption performance of VOCs in activated carbons,including the adsorption equilibrium,adsorption kinetics,and exotherm during adsorption.Subsequently,the existing prediction models are summarized and compared concerning the adsorption equilibrium,adsorption kinetics,and exothermic process of adsorption.We then propose a new prediction model based on intermolecular interaction and provide an outlook toward the design and manipulation of efficient adsorbents for the VOC system. | Shanshan Wang Liangliang Huang Yumeng Zhang Licheng Li Xiaohua Lu | 2021 | Chinese Journal of Chemical Engineering2021，34，3： | 4 |

| 15 | Acrylamide exposure impairs blood-cerebrospinal fluid barrier function显示文摘Previous studies show that chronic acrylamide exposure leads to central and peripheral neuropathy. However, the underlying mechanisms remained unclear. In this study, we examined the permeability of the blood-cerebrospinal fluid barrier, and its ability to secrete transthyretin and transport leptin of rats exposed to acrylamide for 7, 14, 21 or 28 days. Transthyretin levels in cerebrospinal fluid began to decline on day 7 after acrylamide exposure. The sodium fluorescein level in cerebrospinal fluid was increased on day 14 after exposure. Evans blue concentration in cerebrospinal fluid was increased and the cerebrospinal fluid/serum leptin ratio was decreased on days 21 and 28 after exposure. In comparison, the cerebrospinal fluid/serum albumin ratio was increased on day 28 after exposure. Our findings show that acrylamide exposure damages the blood-cerebrospinal fluid barrier and impairs secretory and transport functions. These changes may underlie acrylamide-induced neurotoxicity. | Xue Yao Licheng Yan Lin Yao Weijun Guan Fanxu Zeng Fuyuan Cao Yanshu Zhang | 2014 | Neural Regeneration Research2014，9，5： | 4 |

| 17 | Effect of rice-rice-rape rotation on physicochemical property and bacterial community of rhizosphere soil显示文摘Through collecting rhizosphere soil sample from a 30-year long-term fixed location test site that use“rice-ricerape”crop rotation(RRR)and“rice-rice-fallow”continuous cropping systems(RRF),this paper investigated effects of long-term crop rotation on physicochemical property and bacterial community of rhizosphere soil.Results showed that total nitrogen(TN),total phosphorus(TP)and available potassium(AK)contents in rhizosphere soil under long-term RRR were decreased by 28.09%,15.69%and 6.25%respectively.Alkali-hydrolyzable nitrogen(AN)and available phosphorus(AP)contents were 10.59%and 13.25%higher than those of soil in RRF respectively.Three soil samples collected during different periods also showed that RRR resulted in a lower rhizosphere soil pH than RRF.Clone library analysis revealed that significant difference in rhizosphere soil bacterial community was observed between RRR and RRF continuous cropping.Abundance ofα-Proteobacteria,β-Proteobacteria andγ-Proteobacteria were higher in rhizosphere soil of RRR compared to RRF.pH of rhizosphere soil was significantly correlated with Acidobacteria level,while total organic carbon(TOC)content was significantly correlated with Proteobacteria level.Long-term RRR enhanced conversion of N and P in rhizosphere soil,increased bio-availability to crop,and promoted diversity of soil bacterial community.Bacterial diversity in RRR could be ecological significance in maintaining soil fertility and functionality. | Licheng Zhang Juan Li Mingqing Zhang | 2020 | Oil Crop Science2020，5，3： | 4 |
| 18 | Reducing Energy Loss and Morphology Optimization Manipulated by Molecular Geometry Engineering for Hetero-junction Organic Solar Cells显示文摘of main observation and conclusion Molecular geometry engineering is an efective strategy to control the micromorphology and molecularenergy level in organic photovoltaics(OPVs).Two novel copolymers based on alkysilyl-and chloride-functionalied benzodithiophene(BDT)were designed and synthesized for wide bandgap copolymer donor materials in OPVs.It was found that the two copolymers exhited distinctly different proper-ties in active layer when blended with fulerene-fre acceptor T-4.The chloride-functionalited copolymer PBDTCI-TZ2 with deeper molecular energy leveland better coplanar structure induced more ordered aggregation in blend flm.Thus,the device based on PBDTC-TZ exhibits better energy alinmentwith IT-4F and smallr radiative recombination.furthermore,the non-radiative recombination of PBDTCI-TZ.T-4F based device is about 45 mV lowerthan the PBDTS-TZ/T-4F based device,contributing to a lower enery loss(Ein,and a higher open-cicut voltage(Vc).As a resut,the devices based onthe blend of PBDTC-TZ2.IT-4F exhibit a high power conversion efficiency(PCE)of up to 12.2%with a high Vvoe of 0.837 Vv,higher than that of PBDTSi-TZ:IT-4F,of which the PCE is 11.2%with a Voc of 0.781V. | Guodong Xu Huan Rao Xunfan Liao Youdi Zhang Yuming Wang Zhi Xing Ting Hu Licheng Tan Lie Chen Yiwang Chen | 2020 | Chinese Journal of Chemistry2020，38，12： | 4 |

| 20 | MoS2 Nanosheets Sensitized with Quantum Dots for Room-Temperature Gas Sensors显示文摘The Internet of things for environment monitoring requires high performance with low power-consumption gas sensors which could be easily integrated into large-scale sensor network.While semiconductor gas sensors have many advantages such as excellent sensitivity and low cost,their application is limited by their high operating temperature.Two-dimensional(2D)layered materials,typically molybdenum disulfide(MoS2)nanosheets,are emerging as promising gas-sensing materials candidates owing to their abundant edge sites and high in-plane carrier mobility.This work aims to overcome the sluggish and weak response as well as incomplete recovery of MoS2 gas sensors at room temperature by sensitizing MoS2 nanosheets with PbS quantum dots(QDs).The huge amount of surface dangling bonds of QDs enables them to be ideal receptors for gas molecules.The sensitized MoS2 gas sensor exhibited fast and recoverable response when operated at room temperature,and the limit of NO2 detection was estimated to be 94 ppb.The strategy of sensitizing 2D nanosheets with sensitive QD receptors may enhance receptor and transducer functions as well as the utility factor that determine the sensor performance,offering a powerful new degree of freedom to the surface and interface engineering of semiconductor gas sensors. | Jingyao Liu Zhixiang Hu Yuzhu Zhang HuaYao Li Naibo Gao Zhilai Tian Licheng Zhou Baohui Zhang Jiang Tang Jianbing Zhang Fei Yi Huan Liu | 2020 | Nano-Micro Letters2020，12，5： | 3 |
