| 2 | Preparation of titanium oxycarbide from various titanium raw materials:Part I.Carbothermal reduction显示文摘Carbothermal reduction was performed at temperatures up to 1600°C for vanadium-bearing titanomagnetite,ilmenite concentrate,and high titania slag.The possibility of selective carbothermal reduction was discussed in detail from the viewpoint of thermodynamics,and also tested.The products were analyzed by X-ray diffraction,scanning electron microscopy,and chemical analysis.The results show that it is possible to reduce all iron oxide to metallic iron,and titania to oxycarbide(TiCxOy),without the reduction of other oxides like silica and magnesia. | GAO Chengjun,JIANG Bo,CAO Zhanmin,HUANG Kai,and ZHU Hongmin School of Metallurgical and Ecological Engineering,University of Science and Technology Beijing,Beijing 100083,China | 2010 | Rare Metals2010，29，6： | 7 |
| 3 | Patterns and determinants of wood physical and mechanical properties across major tree species in China显示文摘The physical and mechanical properties of wood affect the growth and development of trees, and also act as the main criteria when determining wood usage. Our understanding on patterns and controls of wood physical and mechanical properties could provide benefits for forestry management and bases for wood application and forest tree breeding. However, current studies on wood properties mainly focus on wood density and ignore other wood physical properties. In this study, we established a comprehensive database of wood physical properties across major tree species in China. Based on this database, we explored spatial patterns and driving factors of wood properties across major tree species in China. Our results showed that(i) compared with wood density, air-dried density, tangential shrinkage coefficient and resilience provide more accuracy and higher explanation power when used as the evaluation index of wood physical properties.(ii) Among life form, climatic and edaphic variables, life form is the dominant factor shaping spatial patterns of wood physical properties, climatic factors the next, and edaphic factors have the least effects, suggesting that the effects of climatic factors on spatial variations of wood properties are indirectly induced by their effects on species distribution. | ZHU JiangLing SHI Yue FANG LeQi LIU XingE JI ChengJun | 2015 | Science China(Life Sciences)2015，58，6： | 4 |

| 5 | The relationships among structure variables of larch forests in China显示文摘Background:Larch(Larix Mill.)forests are widely distributed in the upper parts of mountainous areas in China,playing vital roles in constructing mountain landscapes and maintaining mountain environments.Despite their importance,our knowledges on the large-scale patterns of structure characteristics and the relationships between different structure variables are unclear.In this paper,we investigated 155 plots from 11 natural larch forest types across the country to explore the biogeographic patterns of the structure characteristics and the allometric relationships between different structure variables for Chinese larch forests.Results:The structure characteristics were significantly different among larch forest types.For different larch forest types,the power function fits the relationships between tree height and diameter at breast height(DBH),average DBH and stem density,and taper and stem density well,but with different exponents among larch forest types.The power exponents of the allometric relationships between tree height and DBH for different larch forest types varied from 0.61 to 0.93(mean=0.86)by standard major axis regression(SMA),and from 0.51 to 0.78(mean=0.56)by ordinary least square regression(OLS).The 50%,75%and 95%quantile regression(QR)and OLS indicated that the average DBH and taper of the L.gmelinii forests,L.gmelinii var.principis-rupprechtii forests,and L.sibirica forests were significantly correlated with stem density.Conclusions:The relationship between tree height and DBH showed a power function relationship for all larch forest types in China,but with different exponents.Overall,stem density was negatively correlated with average DBH and taper.The Sect.Larix forests exhibited stand density effect.Our findings provide an important basis for recognizing the biogeographic patterns of structure factors and for the management of larch forests in China. | Wenjing Fang Qing Zhao Qiong Cai Anwar Eziz Guoping Chen Yuhao Feng Heng Zhang Jiangling Zhu Chengjun Ji Zhiyao Tang Jingyun Fang | 2020 | Forest Ecosystems2020，7，4： | 2 |
| 6 | Highly transmitted silver nanowires-SWCNTs conductive flexible film by nested density structure and aluminum-doped zinc oxide capping layer for flexible amorphous silicon solar cells显示文摘Indium tin oxide(ITO)is widely used in transparent conductive films(TCFs);however,several disadvan-tages,such as high cost and toxicity of indium,limit its applications.Therefore,it is necessary to develop other materials that can replace ITO.Silver nanowires or single walled carbon nanotubes(SWCNTs)have attracted considerable interest owing to their unique electrical,optical,and thermal stabilities,and thus,they are ideal for transparent electrodes for flexible or stretchable devices.In this study,we develop a novel architecture of composite TCFs on a polyethylene naphthalate(PEN)flexible substrate.Herein,the silver nanowires-SWCNTs films with nested density structure were fabricated through ultrasonic spraying technology by varying the spraying width.For achieving enhanced transmittance,we combined the larger irregular grids and holes with fewer nanowires stacked in the longitudinal direction,more optical chan-nels,and good carrier transport.Thereafter,aluminum-doped zinc oxide(AZO)was used as capping to the structure for enhancing the optical properties of the TCFs.The silver nanowires-SWCNTs/AZO(ASA)bilayer was obtained in the optimized architecture,which showed superior optoelectronic performance to that shown by commercial ITO with a high optical transmittance of 92%at the wavelength of 550 nm and low sheet resistance of 17/sq.In the specially structured conductive film,the significant improvement in the transmittance and uniformity of the sheet resistance was attributed to the effective nanowire junc-tion contact compared to that in ordinary structure of silver nanowires,which reduced the mean density of small clusters of nanowires.Compared with the silver nanowires-SWCNTs films,the ASA bilayer film exhibited excellent resistance to boiling,mechanical bending(10,000 cycles),and CO_(2)plasma.Moreover,the sheet resistance of ASA changed slightly after the tape tests,thereby illustrating a strong adhesion to the PEN substrate after the enclosure of AZO.Meanwhile,the AZO capping layer can enhance the op-tical transmittance between 600 and 1500 nm.In addition,the amorphous silicon photovoltaic devices with flexible ASA TCFs exhibited a power conversion efficiency(PCE)of 8.67%.After bending for 3000 times,the PCE was decreased to 8.20%,thereby demonstrating the potential of developed films to replace traditional ITO. | Shunliang Gao Xiaohui Zhao Qi Fu Tianchi Zhang Jun Zhu Fuhua Hou Jian Ni Chengjun Zhu Tiantian Li Yanlai Wang Vignesh Murugadoss Gaber A.M.Mersal Mohamed M.Ibrahim Zeinhom M.El-Bahy Mina Huang Zhanhu Guo | 2022 | Journal of Materials Science & Technology2022，，31： | 2 |
| 7 | The study of the adductor muscle-shell interface structure in three Mollusc species显示文摘The adductor muscle scar(AMS) is the fixation point of adductor muscle to the shell. It is an important organicinorganic interface and stress distribution area. Despite recent advances, our understanding of the structure and composition of the AMS remain limited. Here, we report study on the AMS of three bivalves: Mytilus coruscus,Chlamys farreri and Ruditapes philippinarum. Results showed that there were significant differences among their AMS structures. Both M. coruscus and C. farreri were found to have a columnar layer above the nacreous platelet shell structure at the AMS and this layer was more organized in M. coruscus. There was no distinguishable twolayer structure in R. philippinarum. Atomic force microscopy(AFM) and Fourier transform infrared spectroscopy(FT-IR) results showed that the AMS was much smoother than the nacreous inner shell in all the three species and the AMS had minor different compositions from the nacreous shell layer. SDS-PAGE(sodium dodecyl-sulfate polyacrylamide gel electophoresis) study of the proteins isolated from the interface indicated that there was a 70 k Da protein which seemed to be specifically located to the highly organized columnar AMS structure in Mytilus coruscus. Further analysis of this protein showed it contained high level of Asx(Asp+Asn), Glx(Glu+Gln) and Gly.The special structure and composition of the AMS might play important roles in the stability, adhesion and function at this stress distribution site. | ZHU Yaoyao SUN Chengjun SONG Yingfei JIANG Fenghua YIN Xiaofei TANG Min DING Haibing | 2016 | Acta Oceanologica Sinica2016，35，8： | 1 |
| 8 | Differentiated super-enhancers in lung cancer cells显示文摘Super-enhancers(SEs) are regulatory elements with enriched accumulation of key transcription factors.Few studies were done investigating SEs in lung cancers.Here we analyzed epigenetic profiling data to identify SEs in lung cancer cell lines.Enhancers were classified as SEs and typical enhancers(TEs).Most of the TEs were overlapped between normal cell and cancer cells.A great portion of SEs were differentiated comparing these cells.Analysis of GO terms associated with SEs revealed SE remodeling(lost on some sites while gain on others) between normal and lung cancer cells.By comparing the average number of SEs in each GO term in cancer cells with the number in control cells,surprisingly,no GO terms with significantly increased SE number in cancer condition were observed.On the contrary,in aspects such as 'cell-cell adhesion','receptor activity' and'negative regulation of canonical Wnt signaling pathway',the related SEs were significantly reduced in cancer cells.These findings suggest that in lung cancer,cells may not gain decisive gene expression in the related aspect,instead,they may have lost control of the fateful genes.Taken together,our work with the usability of omics data identified SEs in lung cancer cells and further showed cancer-specific features of SE-related terms. | Xin Li Chengjun Lu Qijue Lu Chunguang Li Ji Zhu Tiejun Zhao Hezhong Chen Hai Jin | 2019 | Science China(Life Sciences)2019，62，9： | 1 |

| 12 | Rapid evolution of T2/S-RNase genes in Fragaria linked to multiple transitions from self-incompatibility to self-compatibility显示文摘The T2/RNase gene family is widespread in eukaryotes,and particular members of this family play critical roles in the gametophytic self-incompatibility(GSI) system in plants.Wild diploid strawberry(Fragaria)species have diversified their sexual systems via self-incompatible and self-compatible traits,yet how these traits evolved in Fragaria remains elusive.By integrating the published and de novo assembled genomes and the newly generated RNA-seq data,members of the RNase T2 gene family were systematically identified in six Fragaria species,including three self-incompatible species(Fragaria nipponica,Fragaria nubicola,and Fragaria viridis) and three self-compatible species(Fragaria nilgerrensis,Fragaria vesca,and Fragaria iinumae).In total,115 RNase T2 genes were identified in the six Fragaria genomes and can be classified into three classes(Ⅰ-Ⅲ) according to phylogenetic analysis.The identified RNase T2 genes could be divided into 22 homologous gene sets according to amino acid sequence similarity and phylogenetic and syntenic relationships.We found that extensive gene loss and pseudogenization coupled with small-scale duplications mainly accounted for variations in the RNase T2 gene numbers in Fragaria.Multiple copies of homologous genes were mainly generated from tandem and segmental duplication events.Furthermore,we newly identified five S-RNase genes in three self-incompatible Fragaria genomes,including two in F.nipponica,two in F.viridis,and one in F.nubicola,which fit for typical features of a pistil determinant,including highly pistil-specific expression,highly polymorphic proteins and alkaline isoelectric point(pI),while no S-RNase genes were found in all three selfcompatible Fragaria species.Surprisingly,these T2/S-RNase genes contain at least one large intron(>10 kb).This study revealed that the rapid evolution of T2/S-RNase genes within the Fragaria genus could be associated with its sexual mode,and repeated evolution of the self-compatible traits in Fragaria was convergent via losses of S-RNase. | Wu Chen Hong Wan Fang Liu Haiyuan Du Chengjun Zhang Weishu Fan Andan Zhu | 2023 | Plant Diversity2023，45，2： | 1 |
| 13 | 中国西南亚高山云冷杉林中大熊猫主食竹的地上生物量及其生物和非生物影响因子显示文摘作为大熊猫(Ailuropoda melanoleuca)的主食竹之一,缺苞箭竹(Fargesia denudate)广泛分布在中国西南山地云冷杉林的林下。然而,缺苞箭竹生物量及其分布的驱动因素仍不清楚。本研究基于对王朗大样地(25.2 ha)209个样方(投影面积为20 m×20 m)中的乔木层和灌木层(包括竹子等木质草本)的系统调查,探讨非生物因素(地形和土壤理化性质)和生物因素(乔木密度、乔木总胸高断面积(TBA)和灌木盖度等)对缺苞箭竹地上生物量的影响。研究结果表明,样方缺苞箭竹地上生物量平均为1.17 ton/ha,在209个调查样方中差异很大(0-4.88 ton/ha,95%置信区间)。缺苞箭竹生物量随海拔、坡度和乔木平均胸径的增加而显著增加,随乔木密度、灌木盖度和土壤pH的增加而显著降低,而与乔木TBA、坡向、土壤有机质或总氮含量无显著线性关系。随机森林模型表明,地形和生物因素对缺苞箭竹生物量的影响比土壤理化性质更大。具体来说,地形主要通过改变乔木密度和土壤理化性质来影响缺苞箭竹的生物量。本研究结果可为大熊猫的保护和亚高山云冷杉林的管理提供科学参考。 | Xinyu Xiong Jiangling Zhu Sheng Li Fan Fan Qiong Cai Suhui Ma Haojie Su Chengjun Ji Zhiyao Tang Jingyun Fang | 2022 | Journal of Plant Ecology2022，15，1： | 1 |

| 15 | Alkaline Phosphatase-Initiated Sensitive Responsiveness of Activatable Probes to Hydrogen Sulfide for Accurate Cancer Imaging and Differentiation显示文摘Optical imaging with molecular probes is becoming an essential tool for advancing biological research and clinical applications.However,most currently available molecular probes show limited sensitivity,specificity,and accuracy due to their typical responsiveness to a single stimulation for biomarker-based imaging.In this study,we develop a novel molecular probe that shows alkaline phosphatase(ALP)-instructed sensitive responsiveness to hydrogen sulfide for accurate cancer imaging and differentiation.This designed probe in an aggregated state under physiological conditions bears negatively charged surfaces,giving poor optical response to H_(2)S.The ALP-mediated dephosphorylation reaction yields an assembled product with a positively charged surface,affording significantly aggregation-enhanced responsiveness to H_(2)S with light-up NIR fluorescence at 755 nm.Such charge reversal of assembled probe from negative to positive plays a vital role in allowing precise visualization and differentiation of cancers based on differences in ALP upregulation and H_(2)S content.We envisage that our charge-reversal strategy for multiple-parameter-activated molecule probes will facilitate boosting the specificity and precision of cancer imaging. | Rongchen Wang Kai Yin Muye Ma Tianli Zhu Jinzhu Gao Jie Sun Xuemei Dong Chengjun Dong Xianfeng Gu He Tian Chunchang Zhao | 2022 | CCS Chemistry2022，4，12： | 0 |
| 16 | Tetradentate cyclometalated platinum complex enables high-performance near-infrared electroluminescence with excellent device stability显示文摘Due to the high decay rate of the non-radiative transition of long wavelengths, the molecular design of efficient and stable near-infrared(NIR) electroluminescent materials remains a big challenge. Herein,a new tetradentate cyclometalated platinum(II) complex with an N∧C∧C∧N coordinated framework has been developed and used as a dopant for NIR organic light-emitting diodes(OLEDs). The complex exhibited a short-lived(0.5–1.5 μs) metal-to-ligand charge transfer(MLCT) excited state in doped and neat films. The resulting NIR OLEDs(λ_(EL)= 730 nm) achieved maximum external quantum efficiency(EQE_(max))of 5.2% and radiance of 74626 m W sr^(-1)m^(–2). Of note, the device exhibited excellent stability with operational lifetime of 119 h for LT_(90). This work demonstrated the great potential of tetradentate platinum(II)complexes in the field of NIR OLEDs. | Chengjun Wu Youming Zhang Jingsheng Miao Kai Li Weiguo Zhu Chuluo Yang | 2023 | Chinese Chemical Letters2023，34，2： | 0 |
| 17 | A dual-modality hydrogen sulfide-specific probe integrating chemiluminescence with NIR fluorescence for targeted cancer imaging显示文摘Taking apart in numerous physiological and pathological activities,hydrogen sulfide(H_(2)S)has been selected as an excellent target spot for the early diagnosis of cancer.So far,there are many mature probes that apply single optical imaging to monitor endogenous H_(2)S.Nevertheless,a single modality is not an ideal method to afford accurate diagnostic information in comprehensive biological organisms.Herein,we developed a dual-modal imaging probe BWS.This designed probe showed a specific response to H_(2)S with both chemiluminescence and NIR fluorescence light-up.The concurrence of fluorescence and chemiluminescence signal provided“double insurances”for highly accurate monitoring of H_(2)S.Satisfactorily,this dual-modal imaging probe performed precise visualization of endogenous H_(2)S in living cells and in vivo.We envisaged that this chemiluminescence/fluorescence real-time dual-modality strategy for H_(2)S detection will expand and optimize the multimodal imaging methods for efficient diagnosis and treatment of cancer. | Xuemei Dong Lixin Sun Ziwen Zhang Tianli Zhu Jie Sun Jinzhu Gao Chengjun Dong Rongchen Wang Xianfeng Gu Chunchang Zhao | 2023 | Science China Chemistry2023，66，6： | 0 |
| 18 | Hetero-assembly of gold nanoparticles on a DNA origami template显示文摘Hetero-assembling of spherical building blocks with well-defined spatial distribution holds great significance in developing chiral nanostructures. Herein, a strategy for hetero-assembling of gold nanoparticles(Au NPs) was demonstrated using rigid bifacial DNA origami as templates. By tuning the sizes and the fixed location of Au NPs on DNA origami, right-handed and left-handed Au NPs nanostructures were respectively constructed. Gel electrophoresis indicated the formation of the DNA origami-Au NPs complex and transmission electron microscopy(TEM) visually displayed the arrangement of Au NPs in these two chiral structures. The spatial configuration and 3D geometry of Au NPs were further illustrated by the stereographic TEM with tilting angles from ?30° to 30°. This strategy provides a universal approach to construct the asymmetrical 3D geometries, which may have potential applications in biomimicking and nanophotonics. | Jie Chao Yinan Zhang Dan Zhu Bing Liu Chengjun Cui Shao Su Chunhai Fan Lianhui Wang | 2016 | Science China Chemistry2016，59，6： | 0 |
| 19 | A test of the mycorrhizal-associated nutrient economy framework in two types of tropical rainforests under nutrient enrichments显示文摘Shifts in tree species and their mycorrhizal associations driven by global change play key roles in biogeochemical cycles. In this paper, we proposed a framework of the mycorrhizal-associated nutrient economy(MANE), and tested it using nutrient addition experiments conducted in two tropical rainforests. We selected two tropical rainforests dominated by arbuscular mycorrhizal(AM) and ectomycorrhizal(ECM) trees, and established eighteen20 m×20 m plots in each rainforest. Six nitrogen(N) and phosphorus(P) addition treatments were randomly distributed in each rainforest with three replicates. We examined the differences in soil carbon(C) and nutrient cycling, plant and litter productivity between the two rainforests and their responses to 10-year inorganic N and P additions. We also quantified the P pools of plants, roots, litter, soil and microbes in the two rainforests. Overall,distinct MANE frameworks were applicable for tropical rainforests, in which soil C, N and P were cycled primarily in an inorganic form in the AM-dominated rainforest, whereas they were cycled in an organic form in the ECMdominated rainforest. Notably, the effects of mycorrhizal types on soil P cycling were stronger than those on C and N cycling. The intensified N and P deposition benefited the growth of AM-dominated rainforests instead of ECMdominated rainforests. Our findings underpin the key role of mycorrhizal types in regulating biogeochemical processes, and have important implications for predicting the ecological consequences of global changes. | Qingshui Yu Suhui Ma Xiaofeng Ni Lai Jiang Zhang Zhou Jiangling Zhu Chengjun Ji Zhiyao Tang Xiaoli Cheng Jingyun Fang | 2023 | Forest Ecosystems2023，10，1： | 0 |
| 20 | Environmental heterogeneity regulates species-area relationships through the spatial distribution of species显示文摘Species-area relationships(SARs),also known as species-area curves,are fundamental scaling tools for biodiversity research.Sampling design and taxonomic groups affect the widely cited forms of species-area curves.However,the influence of sampling design and related environmental heterogeneity on SAR curves is rarely considered.Here,we investigated the SAR among different plant life forms(herbaceous plants,shrubs,and trees)in a 25.2-ha ForestGEO plot,the Wanglang Plot,in Sichuan,southwestern China,using a non-contiguous quadrat sampling method and power-law model.We compared the estimated parameters(the intercept c and the slope z)of the power-law models among different plant life forms,tested whether the SAR curve forms varied with sampling starting location,and assessed the effect of environmental heterogeneity accumulating with sampling area on curve variation.We found a wider range of variations in the SARs.The estimated c,z-values of power SAR were higher for the herbaceous plants than for the woody plants.A wider variation of SARs for the herbaceous plants than those for the woody plants.The selection of sampling starting location affected the SAR curve forms because of the roles of soil and topographic heterogeneity.We concluded that environmental heterogeneity regulates SAR curves sampled from different starting locations through spatial distribution of plant life forms.Thus,we recommend considering the design of sampling starting location when constructing SAR curves,especially in a heterogeneous habitat with unrandom distribution patterns of species. | Chenqi He Leqi Fang Xinyu Xiong Fan Fan Yangang Li Luoshu He Xiaoli Shen Sheng Li Chengjun Ji Jiangling Zhu | 2022 | Forest Ecosystems2022，9，3： | 0 |
