4Toxicity of graphene oxide and multi-walled carbon nanotubes against human cells and zebrafish显示文摘Graphene possesses unique physical and chemical properties, which have inspired a wide range of potential biomedical applications. However, little is known about the adverse effects of graphene on the human body and ecological environment. The purpose of our work is to make assessment on the toxicity of graphene oxide (GO) against human cell line (human bone marrow neuroblastoma cell line and human epithelial carcinoma cell line) and zebrafish (Danio rerio) by comparing the toxic effects of GO with its sister, multi-walled carbon nanotubes (MWNTs). The results show that GO has a moderate toxicity to organisms since it can induce minor (about 20%) cell growth inhibition and slight hatching delay of zebrafish embryos at a dosage of 50 mg/L, but did not result in significant increase of apoptosis in embryo, while MWNTs exhibit acute toxicity leading to a strong inhibition of cell proliferation and serious morphological defects in developing embryos even at relatively low concentration of 25 mg/L. The distinctive toxicity of GO and MWNTs should be ascribed to the different models of interaction between nanomaterials and organisms, which arises from the different geometric structures of nanomaterials. Collectively, our work suggests that GO does actual toxicity to organisms posing potential environmental risks and the result is also shedding light on the geometrical structure-dependent toxicity of graphitic nanomaterials.CHEN LiQiang HU PingPing ZHANG Li HUANG SiZhou LUO LingFei HUANG ChengZhi 2012Science China Chemistry2012,55,10:12
5Sisyphus effects in hydrogen electrochemistry on metal silicides enabled by silicene subunit edge显示文摘Nonmetal elements strictly govern the electrochemical performance of molybdenum compounds.Yet,the exact role played by nonmetals during electrocatalysis remains largely obscure.With intermetallic MoSi_2comprising silicene subunits,we present an unprecedented hydrogen evolution reaction(HER)behavior in aqueous alkaline solution.Under continuous operation,the HER activity of MoSi_2shows a more than one order of magnitude improvement in current density from 1.1 to 21.5 mA cm^(à2)at 0.4 V overpotential.Meanwhile,this activation behavior is highly reversible,such that voltage withdrawal leads to catalyst inactivation but another operation causes reactivation.Thus,the system shows dynamics strikingly analogous to the legendary Sisyphus’labor,which drops and recovers in a stepwise manner repeatedly,but never succeeds in reaching the top of the mountain.Isomorphic WSi_2behaves almost the same as MoSi_2,whereas other metal silicides with silicyne subunits,including CrSi_2and TaSi_2,do not exhibit any anomalous behavior.A thin amorphous shell of MoSi_2is observed after reaction,within which the Si remains partially oxidized while the oxidation state of Mo is basically unchanged.First-principles calculations further reveal that the adsorption of hydroxide ions on silicene subunit edges and the subsequent Si vacancy formation in MoSi_2jointly lead to the anomalous HER kinetics of the adjacent Mo active centers.This work demonstrates that the role of nonmetal varies dramatically with the electronic and crystallographic structures of silicides and that silicene structural subunit may serve as a promoter for boosting HER in alkaline media.Zechao Zhuang Yong Li Jiazhao Huang Zilan Li Kangning Zhao Yunlong Zhao Lin Xu Liang Zhou Lyudmila V.

6The fluctuating environment associated with the episodic biotic crisis during the Permo/Triassic transition:Evidence from microbial biomarkers in Changxing,Zhejiang Province显示文摘The environmental conditions and the biotic crisis during the Permo-Triassic (Tr/P) transition received increasing attention in the past decades. Presented herein are the molecular fossil records of cyano-bacteria and green sulfur bacteria,the base of the marine ecosystem,to highlight the episodic nature of both the environment and the biotic crisis during this critical period. At least two episodes of cyano-bacterial expansion are documented by 2-methylhopanes ranging from C28 to C32 in carbon number,indicative of the instable marine ecosystem and the fluctuant aquatic nutrients. Meanwhile,the index of 2-alkyl-1,3,4-trimethylbenzenes (biomarkers of green sulfur bacteria) and the ratio of pristane to phy-tane (Pr/Ph) witness the fluctuation of sedimentary environmental redox conditions. The above mo-lecular evidence suggests the occurrence of highly fluctuating environmental conditions during the Tr/P transition,which is consistent with,and probably the cause of,the multi-phased biotic crisis and the prolonged faunal recovery.HUANG XianYu JIAO Dan LU LiQiang XIE ShuCheng HUANG JunHua WANG YongBiao YIN HongFu WANG HongMei ZHANG KeXin LAI XuLong 2007Science China Earth Sciences2007,50,7:10
7Tectonic Constraints on the Transformation of Paleozoic Framework of Uplift and Depression in the Ordos Area显示文摘During the Paleozoic, the Ordos area in the western North China Plate was located at the intersecting position of microplates and controlled by their interaction. The structural framework in the Ordos area, which underwent transformations in the Ordovician, the Carboniferous and the Permian respectively, was dominated by the alternation of uplift and depression. The transformations of structural framework are utilized as the clues to investigate the microplates’ interacting type and its response in the Ordos area. According to the regional structural evolution, the Ordos area is simplified into an isopachous, isotropic and elastic shell model, and under proposed various boundary conditions, three series of numerical simulations corresponding to the three structural transformations are carried out to determine the detailed tectonic constraints. Numerical simulations reveal that the structure of the uplift and depression, which is similar to the actual pattern, develops only under one special boundary condition in each of the three series, indicating that the structural framework responds to the unique tectonic background. The simulation results show that in the Early Paleozoic, the L-shaped paleouplift formed nearby the southwestern corner of the Ordos area because the intensity of the compressions in the southern and western boundaries resulting from the ocean-continent collisions was similar. In the Late Paleozoic, it evolved into continent-continent (or arc-continent) interaction in the southern and northern boundaries; in the preliminary stage of the interaction, since the interface between the North China Plate and the plates on the south and north was narrow, the relative acting force was little and the regional western boundary immobile, and the structural framework in the basin was characterized by the N-S trending slender-waist-shaped uplift; as the interface between the plates expanded gradually, the extrusive force in the southern and northern boundaries of the North China Plate increased, resulting in the paleogeographic divisions showing E-W trending, and, the western boundary of the basin was extruded westward due to the intense compression inducing the local NE trending of paleogeographic division in the central area. The simulation results further reflect that the symmetry of the uplift-depression pattern is restricted by that of the boundary conditions, suggesting that the Paleozoic structural transformations of the Ordos area under boundary constraints accord with the universal physical symmetrical principle.WANG Qingfei DENG Jun HUANG Dinghua YANG Liqiang GAO Bangfei XU Hao JIANG Shaoqing 2006Acta Geologica Sinica(English Edition)2006,80,6:10
8Novel MOF shell-derived surface modification of Li-rich layered oxide cathode for enhanced lithium storage显示文摘Li-rich layered oxide materials have attracted increasing attention because of their high specific capacity(>250 mAh g^(-1)). However, these materials typically suffer from poor cycling stability and low rate performance. Herein, we propose a facile and novel metal-organic-framework(MOF) shell-derived surface modification strategy to construct NiCo nanodots decorated(~5 nm in diameter) carbon-confined Li_(1.2)Mn_(0.54) Ni_(0.13)Co_(0.13)O_2 nanoparticles(LLO@C&NiCo). The MOF shell is firstly formed on the surface of as-prepared Li_(1.2)Mn_(0.54)Ni_(0.13)Co_(0.13)O_2 nanoparticles via low-pressure vapor superassembly and then is in situ converted to the NiCo nanodots decorated carbon shell after subsequent controlled pyrolysis.The obtained LLO@C&NiCo cathode exhibits enhanced cycling and rate capability with a capacity retention of 95% after 100 cycles at 0.4 C and a high capacity of 159 mAh g^(-1) at 5 C, respectively, compared with those of LLO(75% and 105 mAh g^(-1)). The electrochemical impedance spectroscopy and selected area electron diffraction analyses after cycling demonstrate that the thin C&NiCo shell can endow LLO with high electronic conductivity and structural stability, indicating the undesired formation of the spinel phase initiated from the particle surface is efficiently suppressed. Therefore, this presented strategy may open a new avenue on the design of high-performance electrode materials for energy storage.Zhitong Xiao Jiashen Meng Qi Li Xuanpeng Wang Meng Huang Ziang Liu Chunhua Han Liqiang Mai 2018Science Bulletin2018,63,1:8
9Huge thick conglomerate movement induced by full thick longwall mining huge thick coal seam显示文摘A discrete elemental method was used to study the thickness of conglomerate layer in a full thick seam mining activities under the influence of the law, pointing out the thickness of the conglomerate at different seam mining, and during the destruction and instability of existing state of laws. At 21141 thick seam mining, the face toward the direction of separation between the thick layer of conglomerate rock and the next bit after reaching its maximum capacity due to pull from the bottom of the plastic zone, formed a stratified and hierarchical down collapse. The shape of caving area is a ''triangular block'', the length of the plastic zone and face advancement from the linear fit between the height of the plastic zone and the advancing face is a quadratic function of distance, while the top layer of thick gravel layer is the overall bending subsidence trend. Tilting the direction of the face, a thick gob of collapsed conglomerate layer is formed in the coal gob entity on both sides of the thick conglomerate at the top of the overall fracture morphology performance, thus forming a mutual extrusion of articulated block structure. The instability, separation and balance of the thick conglomerate layer in the hinged block stope stress leads to abnormal occurrence of rock burst induced by face as the major factor in the accident. This research reveals the form of stress distribution in the destroyed layer of the thick conglomerate rock, analyzes the stope law of coupling for the pressure burst behavior law for the mining work face, and the choice of preventive measures to provide a theoretical basis and implementation.Ma Liqiang Qiu xiaoxiang Dong Tao Zhang Jixiong Huang Yanli 2012International Journal of Mining Science and Technology2012,22,3:7
10Comprehensive Mineral Nutrition Analysis of Watermelon Grafted onto Two Different Rootstocks显示文摘Grafting is a widely used practice in fruit-bearing vegetables. However, why grafting affects plant growth, fruit yield, and quality, especially from the aspect of mineral nutrition, remains unclear. In this study, watermelon cultivar ‘Zaojia 8424' was grafted onto bottle gourd ‘Jingxinzhen1'(Lagenaria siceraria) and pumpkin ‘Qingyanzhen 1'(Cucurbita maxima × C. moschata). Non-grafted plants were used as the control. Results show that rootstock grafting significantly increases plant growth and single fruit weight of watermelon. Watermelon grafted onto rootstocks, especially pumpkin, exhibits significantly higher root volume, root surface area, and number of root tips and forks in comparison with non-grafted plants. Fruit flesh, rind firmness, and rind thickness were enhanced by grafting. However, fruit soluble solids and taste significantly decreased in plants grafted onto pumpkin. The total uptake(mg · plant^(-1)) and concentration(mg · g^(-1)DW) of N, K, Ca, Fe, Mg, and Mn in root, stem, leaf,fruit rind, and flesh were generally higher in grafted plants compared to non-grafted ones, especially for N of pumpkin rootstock-grafted plants.The total uptake of nutrients of plants grafted onto bottle gourd and pumpkin was increased by 30.41% and 49.14% at fruit development stage and by 21.33% and 47.46% at fruit maturation stage, respectively, compared with non-grafted plants. We concluded that watermelon grafting onto suitable rootstocks can increase the uptake of mineral nutrition, especially for N in the pumpkin rootstock grafted plants, thereby affecting plant growth, fruit yield, and quality.HUANG Yuan ZHAO Liqiang KONG Qiusheng CHENG Fei NIU Mengliang XIE Junjun Muhammad Azher Nawaz BIE Zhilong 2016Horticultural Plant Journal2016,2,2:7
11Effects of the Fhb1 gene on Fusarium head blight resistance and agronomic traits of winter wheat显示文摘The gene Fhb1 has been used in many countries to improve wheat Fusarium head blight(FHB) resistance. To make better use of this gene in the Yellow-Huai River Valleys Winter Wheat Zone(YHWZ), the most important wheat-producing region of China, it is desirable to elucidate its effects on FHB resistance and agronomic traits in different genetic backgrounds. Based on a diagnostic marker for Fhb1, six BC2 populations were developed by crossing dwarf-male-sterile(DMS)-Zhoumai 16 to three Fhb1 donors(Ningmai 9, Ningmai 13, and Jianyang 84) and backcrossing to Zhoumai 16 and Zhoumai16’s derivative cultivars(Lunxuan 136 and Lunxuan 13) using marker-assisted backcross breeding. The progenies were assessed for FHB resistance and major agronomic traits.The Fhb1 alleles were identified using the gene-specific molecular marker. The plants with the Fhb1-resistant genotype(Fhb1-R) in these populations showed significantly fewer infected spikelets than those with the Fhb1-susceptible genotype(Fhb1-S). When Lunxuan 136 was used as the recurrent parent, Fhb1-R plants showed significantly fewer infected spikelets per spike than Fhb1-R plants produced using Lunxuan 13 as the recurrent parent, indicating that the genetic backgrounds of Fhb1 influence the expression of FHB resistance. Fhb1-R plants from the DMS-Zhoumai 16/Ningmai 9//Zhoumai 16/3/Lunxuan 136 population showed the highest FHB resistance among the six populations and a significantly higher level of FHB resistance than the moderately susceptible control Huaimai 20. No significant phenotypic differences between Fhb1-R and Fhb1-S plants were observed for the eight agronomic traits investigated. These results suggest that it is feasible to improve FHB resistance of winter wheat withoutreducing yield potential by introgressing Fhb1 resistance allele into FHB-susceptible cultivars in the YHWZ.Teng Li Hongjun Zhang Yiwen Huang Zhenqi Su Yun Deng Hongwei Liu Chunyan Mai Guangjun Yu Huili Li Liqiang Yu Tongquan Zhu Li Yang Hongjie Li Yang Zhou 2019The Crop Journal2019,7,6:6

14Temporal and spatial cellular and molecular pathological alterations with single-cell resolution in the adult spinal cord after injury显示文摘Spinal cord injury(SCI)involves diverse injury responses in different cell types in a temporally and spatially specific manner.Here,using single-cell transcriptomic analyses combined with classic anatomical,behavioral,electrophysiological analyses,we report,with single-cell resolution,temporal molecular and cellular changes in crush-injured adult mouse spinal cord.Data revealed pathological changes of 12 different major cell types,three of which infiltrated into the spinal cord at distinct times post-injury.We discovered novel microglia and astrocyte subtypes in the uninjured spinal cord,and their dynamic conversions into additional stage-specific subtypes/states.Most dynamic changes occur at 3-days post-injury and by day-14 the second wave of microglial activation emerged,accompanied with changes in various cell types including neurons,indicative of the second round of attacks.By day-38,major cell types are still substantially deviated from uninjured states,demonstrating prolonged alterations.This study provides a comprehensive mapping of cellular/molecular pathological changes along the temporal axis after SCI,which may facilitate the development of novel therapeutic strategies,including those targeting microglia.Chen Li Zhourui Wu Liqiang Zhou Jingliang Shao Xiao Hu Wei Xu Yilong Ren Xingfei Zhu Weihong Ge Kunshan Zhang Jiping Liu Runzhi Huang Jing Yu Dandan Luo Xuejiao Yang Wenmin Zhu Rongrong Zhu Changhong Zheng Yi Eve Sun Liming Cheng 2022Signal Transduction and Targeted Therapy2022,7,4:4
15A simple model of radial nerve injury in the rhesus monkey to evaluate peripheral nerve repair显示文摘Current research on bone marrow stem cell transplantation and autologous or xenogenic nerve transplantation for peripheral nerve regeneration has mainly focused on the repair of peripheral nerve defects in rodents.In this study,we established a standardized experimental model of radial nerve defects in primates and evaluated the effect of repair on peripheral nerve injury.We repaired 2.5-cm lesions in the radial nerve of rhesus monkeys by transplantation of autografts,acellular allografts,or acellular allografts seeded with autologous bone marrow stem cells.Five months after surgery,regenerated nerve tissue was assessed for function,electrophysiology,and histomorphometry.Postoperative functional recovery was evaluated by the wrist-extension test.Compared with the simple autografts,the acellular allografts and allografts seeded with bone marrow stem cells facilitated remarkable recovery of the wrist-extension functions in the rhesus monkeys.This functional improvement was coupled with radial nerve distal axon growth,a higher percentage of neuron survival,increased nerve fiber density and diameter,increased myelin sheath thickness,and increased nerve conduction velocities and peak amplitudes of compound motor action potentials.Furthermore,the quality of nerve regeneration in the bone marrow stem cells-laden allografts group was comparable to that achieved with autografts.The wrist-extension test is a simple behavioral method for objective quantification of peripheral nerve regeneration.Dong Wang Xijun Huang Guo Fu Liqiang Gu Xiaolin Liu Honggang Wang Jun Hu Jianhua Yi Xiaofeng Niu Qingtang Zhu 2014Neural Regeneration Research2014,9,10:3
16A writable lithium metal ink显示文摘The recent revival of Li metal anodes(LMA)leads to a renewed interest in LMA as the ultimate choice for rechargeable lithium batteries towards high energy density.However,multiple challenges stand in the way of using LMA,of which high reactivity,dendrite growth,the difficulty of fabricating Li thin foils,and the flammability of organic liquid electrolytes are typical.Here,a writable Li metal ink(LMI)prepared by introducing biomass-derived carbon particles into molten Li is presented.Due to the significantly decreased surface tension,LMI is able to directly write on copper foils or other substrates that ultrathin Li foils with a remarkably small thickness(<10μm)can be achieved.The versatility of LMI is further demonstrated in addressing the interface issue between LMA and garnet-type solid-state electrolytes,where directly writing LMI on the garnet offers a perfect contact and enables an extremely low interfacial resistance of 6Ωcm^2,in sharp contrast to 939Ωcm^2 between the pure Li and the garnet.Due to the successful partnership with non-flammable solid-state electrolytes,ink-based technology may have a chance to bring us very close to the use of solid-state lithium metal batteries(SSLMBs)with high safety and high energy density.Wangyan Wu Jian Duan Jiayun Wen Yuwei Chen Xuyang Liu Liqiang Huang Zhengfeng Wang Shengyuan Deng Yunhui Huang Wei Luo 2020Science China Chemistry2020,63,10:2
17MXene-Ti3C2Tx for watt-level high-efficiency pulse generation in a 2.8μm mid-infrared fiber laser显示文摘We report a watt-level passively Q switched 2.8μm mid-infrared multi-mode fiber laser by employing multi-layered two dimensional MXene-Ti3C2Tx as the saturable absorber(SA).The MXene-Ti3C2Tx is fabricated by selectively etching aluminum layers in Ti3AlC2.The non-saturable loss,modulation depth,and saturable inten-sity of the SA at 2866 nm were measured to be 25.0%,33.2%,and 0.043 GW/cm^2,respectively.The maximum average output power of the Ti3C2Tx Q-switched fiber laser reached 1.09 W at 28.23%slope fficiency.The pulse repetition rate,shortest pulse width,pulse peak power,and single-pulse energy were 78.12 kHz,1.04μs,13.4 W,and 13.93μJ,respectively.This is the frst demonstration of watt-level pulse gencration in a mid-infrared fiber laser using low dimensional materials,to the best of our knowledge.These results indicate that the Ti3C2Tx is a reliable and superior broadband SA for high power mid-infrared pulsed laser generation.CHEN WEI LIQIANG ZHOU DONGSHENG WANG HAO CHI Hua HUANG HAN ZHANG YONG LIU 2020Photonics Research2020,8,6:2

19Highly stable Al-doped ZnO by ligand-free synthesis as general thickness-insensitive interlayers for organic solar cells显示文摘Highly conductive and dispersible Al-doped ZnO(AZO) nanoparticles(NPs) have been successfully prepared by ligand-free colloidal synthesis at low temperature and stabilization by surfactant-aid including ethanolamine(EA), ethylenediamine(EDA),diethylenetriamine(DETA) and triethylenetetramine(TETA). Due to the strong intermolecular hydrogen-bonding interactions between AZO NPs and the amino groups from surfactants, the inevitable aggregation was suppressed and the surface defect sites were passivated obviously. The existence of electron transfer from the nitrogen of the amino groups to the zinc of AZO,led to a dramatic increase in electrical conductivity. A homogeneous current intensity value up to ~2200 pA for AZO tread by DETA was characterized by conductive atomic force microscopy(C-AFM), which was more superior than that of the reported sol-gel synthesized AZO with the assistance of EA surfactant(refer to 170.7 pA). Furthermore, non-fullerenes solar cells based on PBDB-T:ITIC with AZO-DETA(80 nm) yielded a best device efficiency of 10.7% and kept up prominent PCE exceeding 10%even with more thicker interlayer(95 nm).Yilin Wang Zhongyou Peng Shuqin Xiao Jia Yang Huanyu Zhou Liqiang Huang Lulu Sun Yinhua Zhou Licheng Tan Yiwang Chen 2018Science China Chemistry2018,61,1:2
