| 1 | LDHs derived nanoparticle-stacked metal nitride as interlayer for long-life lithium sulfur batteries显示文摘Shuttle effect is one of the most serious disadvantages in lithium-sulfur battery which results in poor cycle performance and hinders the commercialization of Li-S battery.To reduce the dissolution of polysulfides into the electrolyte and prolong the cycling stability,nanoparticle-stacked metal nitride derived from layered double hydroxides(LDHs)as an interlayer was inserted between sulfur cathode and separator to confine polysulfides by physical and chemical interactions.Meanwhile,the surface of metal nitride will form an oxide passivation layer.The passivation layer possesses hydrophilic metal-O group and provides a polar surface for strong binding with polysulfide.What’s more,the nanoparticlesstacked structure could immerge and retain electrolyte well,which could enhance the ability of promoting the electron exchange rate.The sulfur electrode with nanoparticle-stacked metal nitride interlayer has an excellent cycle performance owing to the interactions between metal nitride and polysulfides.The battery delivered an initial capacity of 764.6 m Ahg^(-1) and still possesses a capacity of 477.5 mAhg^(-1) with the retention of 62.4% after 800 cycles. | Zhen Li Zhaoling Ma Yanyong Wang Ru Chen Zhenjun Wu Shuangyin Wang | 2018 | Science Bulletin2018，63，3： | 8 |
| 2 | Apoptosis in glioma-bearing rats after neural stem cell transplantation显示文摘Abnormal activation of the Ras/Raf/Mek/Erk signaling cascade plays an important role in glioma. Inhibition of this aberrant activity could effectively hinder glioma cell proliferation and promote cell apoptosis. To investigate the mechanism of glioblastoma treatment by neural stem cell transplantation with respect to the Ras/Raf/Mek/Erk pathway, C6 glioma cells were prepared in suspension and then infused into the rat brain to establish a glioblastoma model. Neural stem cells isolated from fetal rats were then injected into the brain of this glioblastoma model. Results showed that Raf-1, Erk and Bcl-2 protein expression significantly increased, while Caspase-3 protein expression decreased. After transplantation of neural stem cells, Raf-1, Erk and Bcl-2 protein expression significantly decreased, while Caspase-3 protein expression significantly increased. Our findings indicate that transplantation of neural stem cells may promote apoptosis of glioma cells by inhibiting Ras/Raf/Mek/Erk signaling, and thus may represent a novel treatment approach for glioblastoma. | Hua Li Zhenjun Chen Shaopeng Zhou | 2013 | Neural Regeneration Research2013，8，19： | 5 |
| 3 | High-throughput 3D reconstruction of stochastic heterogeneous microstructures in energy storage materials显示文摘Stochastic heterogeneous microstructures are widely applied in structural and functional materials,playing a crucial role in determining their performance.X-ray tomography and focused ion beam serial sectioning are frequently used methods to reconstruct three-dimensional(3D)microstructures,yet are demanding techniques and are resolution-limited.Here,a highthroughput multi-stage 3D reconstruction method via distance correlation functions is developed using a single representatively large-sized 2D micrograph for stochastic microstructures,and verified by X-ray micro-tomography datasets of isotropic and anisotropic solid oxide fuel cell electrodes.This method provides an economic,easy-to-use and high-throughput approach for reconstructing stochastic heterogeneous microstructures for energy conversion and storage devices,and can readily be extended to other materials. | Yanxiang Zhang Mufu Yan Yanhong Wan Zhenjun Jiao Yu Chen Fanglin Chen Changrong Xia Meng Ni | 2019 | npj Computational Materials2019，，1： | 3 |
| 4 | Computer Simulation of Mechanical Properties of Nano-scale Cu/FeS Composite显示文摘The mechanical properties of nano-scale Cu/FeS composite were simulated by molecular dynamics (MD) simulation in this paper. Through the analysis on the stress-strain curves, the results of MD simulation were in good agreement with mechanisms of macroscopic deformation. When the size of particles was smaller than a certain value, the relationship between yield strength and size, which was different from the large size crystals abided by the contrary Hall-Petch relationship. Based on the discussion of nano-scale Cu/FeS composite, some interesting conclusions were obtained. For example, the 'S' type curves were discovered in stress-strain curves and the anisotropy of FeS was very evident when the exposures of reinforcing phase (FeS) were different and so on. The basic theories and calculations of the composite that contains nano-scale particles were discussed. At the same time, a new modeling building method of composites, which was close to actual experiences, were considered in this paper. | Zhenjun Hong Jingchao Chen Jing Feng Yeping Du Jie Yu Lijuan Zhang Shuzhen Wu Futai Xu | 2010 | Journal of Materials Science & Technology2010，26，4： | 2 |
| 5 | Spatial variations in the trophic status of Favia palauensis corals in the South China Sea:Insights into their different adaptabilities under contrasting environmental conditions显示文摘Scleractinian corals exhibit a dual trophic pattern of autotrophic photosynthesis and heterotrophic predation.However,whether corals can adjust their trophic status under contrasting environmental conditions remains unclear.In our study,70 scleractinian corals(Favia palauensis)were collected from Sanya and the Xisha and Nansha Islands in the South China Sea.We measured the zooxanthellae density(ZD)andδ^(13)C of zooxanthellae(δ^(13)C_(z))and host tissue(δ^(13)C_(h))and analyzed the difference betweenδ^(13)C_(h) andδ^(13)C_(z)(i.e.,△^(h-z)^(13)C).The relatively high ZD andδ^(13)C_(z) values in the samples from Sanya indicate that these corals might have higher photosynthetic rates and autotrophic abilities than those from Xisha and Nansha.In contrast,the relatively lowδ^(13)C_(h) and△^(h-z)^(13)C values in the samples from Xisha and Nansha suggest that these corals might have a higher heterotrophic ability than those from Sanya.In addition,we tested the coral tissue biomass and skeletalδ^(13)C(δ^(13)C_(s))in the samples from Sanya and examined their correlations with△^(h-z)^(13)C.The results showed a negative correlation,indicating that the more the organic material produced by the coral,the stronger its heterotrophic ability.Our results show that corals can adjust their trophic status under different environmental and physiological conditions,which is essential for increasing their adaptability to different environmental conditions. | Shendong XU Zhinan ZHANG Kefu YU Xueyong HUANG Hanji CHEN Zhenjun QIN Risheng LIANG | 2021 | Science China Earth Sciences2021，64，6： | 2 |
| 6 | Super-absorbent swellable polymer as grouting material for treatment of karst water inrush显示文摘Grouting is the most commonly used method to control water inrush in underground engineering.Traditional cement-based materials are easy to dilute and hard to coagulate under the influence of large flow and high-velocity water inrush.To address these deficiencies,a new type of polymer grouting material with an excellent expansion ratio was synthesised.The material quickly absorbs water and has an expansion ratio of 1:300.The material is composed of a superabsorbent polymer(SAP),glycerol,and ethanol.The effects of water quality on the expansion ratio and expansion rate of the material were examined,and the best solid–liquid ratio for the slurry was determined by fluidity measurements.A karst specially designed pipeline water inrush test device showed that 800 g of SAP can achieve 0.6 m/s water flow blockage in the smooth pipeline,demonstrating that the ability of the SAP slurry to block water inrush is superior to those of other materials.This study provides a reference for water inrush plugging,and has important implications for the reduction and control of karst pipeline-type water inrush disasters,ensuring the safety of construction sites and preventing loss of life and damage to property. | Shucai Li Chenyang Ma Rentai Liu Mengjun Chen Jia Yan Zhenjun Wang Shaolong Duan Huasheng Zhang | 2021 | International Journal of Mining Science and Technology2021，31，5： | 2 |

| 8 | Sericin protects against diabetes-induced injuries in sciatic nerve and related nerve cells显示文摘Sericin from discarded silkworm cocoons of silk reeling has been used in different fields,such as cosmetology,skin care,nutrition,and oncology.The present study established a rat model of type 2 diabetes by consecutive intraperitoneal injections of low-dose (25 mg/kg) streptozotocin.After intragastrical perfusion of sericin for 35 days,blood glucose levels significantly declined,and the expression of neurofilament protein in the sciatic nerve and nerve growth factor in L4-6 spinal ganglion and anterior horn cells significantly increased.However,the expression of neuropeptide Y in spinal ganglion and anterior horn cells significantly decreased in model rats.These findings indicate that sericin protected the sciatic nerve and related nerve cells against injury in a rat type 2 diabetic model by upregulating the expression of neurofilament protein in the sciatic nerve and nerve growth factor in spinal ganglion and anterior horn cells,and downregulating the expression of neuropeptide Y in spinal ganglion and anterior horn cells. | Chengjun Song Zhenjun Yang Meirong Zhong Zhihong Chen | 2013 | Neural Regeneration Research2013，8，6： | 2 |

| 10 | Growth of 12-inch uniform monolayer graphene film on molten glass and its application in PbI2-based photodetector显示文摘Direct growth of large area uniform graphene on functional insulating materials is essential for engineering versatile applications of graphene. However, the existing synthesis approaches can hardly avoid the generation of non-uniform multilayer graphene along the gas flow direction, affording huge challenges for further scaling up. Herein, by exploiting the molten state of soda-lime glass, we have accomplished the direct growth of large area uniform (up to 30 cm × 6 cm) graphene via a facile chemical vapor deposition route on low cost soda-lime glass. The use of molten glass eliminates the chemically active sites (surface corrugations, scratches, defects), and improves the mobility of carbon precursors, affording uniform nucleation and growth of monolayer graphene. Intriguingly, thus-obtained graphene acts as an ideal coating layer for the surface crystallographic modification of soda-lime glass, making it epitaxy substrates for synthesizing high-quality PbI2 nanoplates and continues films. Accordingly, a prototype photodetector was fabricated to present excellent photoelectrical properties of high responsivity (~ 600 on/off current ratio) and fast response speed (18 μs). This work hereby paves ways for the batch production and the direct applications of graphene glass as platforms for constructing high performance electronic and optoelectronic devices. | Zhaolong Chen Haina Ci Zhenjun Tan Zhipeng Dou Xu-dong Chen Bingzhi Liu Ruojuan Liu Li Lin Lingzhi Cui Peng Gao Hailin Peng Yanfeng Zhang Zhongfan Liu | 2019 | Nano Research2019，12，8： | 1 |

| 12 | Estrogen intervention in microvascular morphology and choline acetyltransferase expression in rat hippocampal neurons in chronic cerebral ischemia显示文摘We observed dynamic changes in microvessels and a protective effect of estrogen on chronic cerebral ischemia ovariectomized rat models established through permanent occlusion of bilateral carotid arteries at 7,14 and 21 days.The results revealed that estrogen improved microvasculature in the hippocampus of chronic cerebral ischemic rats,upregulated Bcl-2 protein expression,downregulated Bax protein expression,increased choline acetyltransferase expression in hippocampal cholinergic neurons,and suppressed hippocampal neuronal apoptosis.These findings indicate that estrogen can protect hippocampal neurons in rats with chronic cerebral ischemia. | Zhenjun Yang Hongwei Yan Guomin Zhang Zhihong Chen Jingfeng xue | 2011 | Neural Regeneration Research2011，6，17： | 1 |
| 13 | Room-Temperature Assembled MXene-Based Aerogels for High Mass-Loading Sodium-Ion Storage显示文摘Low-temperature assembly of MXene nanosheets into three-dimensional(3D) robust aerogels addresses the crucial stability concern of the nano-building blocks during the fabrication process,which is of key importance for transforming the fascinating properties at the nanoscale into the macroscopic scale for practical applications.Herein,suitable cross-linking agents(amino-propyltriethoxysilane,Mn^(2+),Fe^(2+),Zn^(2+),and Co^(2+)) as interfacial mediators to engineer the interlayer interactions are reported to realize the graphene oxide(GO)-assisted assembly of Ti_(3)C_(2)T_(x) MXene aerogel at room temperature.This elaborate aerogel construction not only suppresses the oxidation degradation of Ti_(3)C_(2)T_(x) but also generates porous aerogels with a high Ti_(3)C_(2)T_(x) content(87 wt%) and robustness,thereby guaranteeing the functional accessibility of Ti_(3)C_(2)T_(x) nanosheets and operational reliability as integrated functional materials.In combination with a further sulfur modification,the Ti_(3)C_(2)T_(x) aerogel electrode shows promising electrochemical performances as the freestanding anode for sodium-ion storage.Even at an ultrahigh loading mass of 12.3 mg cm^(-2),a pronounced areal capacity of 1.26 mAh cm^(-2) at a current density of 0.1 A g^(-1) has been achieved,which is of practical significance.This work conceptually suggests a new way to exert the utmost surface functionalities of MXenes in 3D monolithic form and can be an inspiring scaffold to promote the application of MXenes in different areas. | Fei Song Jian Hu Guohao Li Jie Wang Shuijiao Chen Xiuqiang Xie Zhenjun Wu Nan Zhang | 2022 | Nano-Micro Letters2022，14，2： | 1 |

| 16 | Development of a Widely Applicable and Simple Prognostic Score for Patients with Acute-on-chronic Liver Failure显示文摘Background and Aims:Acute-on-chronic liver failure(ACLF)tends to progress rapidly with high short-term mortality.We aimed to create a widely applicable,simple prognostic(WASP)score for ACLF patients.Methods:A retrospective cohort of ACLF cases recruited from three centers in China were divided into training and validation sets to develop the new score.A prospective longitudinal cohort was recruited for further validation.Results:A total of 541 cases were included in the training set,and seven independent ACLF prognostic factors were screened to construct a new quantitative WASP-ACLF table.In the validation set of 671 cases,WASP-ACLF showed better predictive ability for 28-day and 90-day mortality than the currently used prognostic scores at baseline,day 3,week 1,and week 2.The predictive efficacy and clinical validity of the model improved over time.Patients were assigned to low-,intermediate-,and high-risk groups by their WASP-ACLF scores.Compared with the other two groups,intermediate-risk patients had a more uncertain prognosis,with a 90-day mortality of 44.4–50.6%.Sequential assessments at weeks 1 and 2 found the 90-day mortality of intermediate-risk groups was<20%forpatients with a≥2 point decrease in WASP-ACLF and was up to 56%for patients with a≥2 points increase.Similar results were observed in prospective data.Conclusions:The new ACLF prognostic score was simple,widely applicable,and had good predictive efficacy.Continuous assessments and trend of change in WASP-ACLF need to be considered,especially for intermediate-risk patients. | Zhenjun Yu Yu Zhang Yuhan Li Feng Zhou Manman Xu Shaoli You Yu Chen Bing Zhu Ming Kong Fangjiao Song Shaojie Xin Zhongping Duan Tao Han China Network for Severe Liver Diseases | 2022 | Journal of Clinical and Translational Hepatology2022，10，5： | 1 |

| 20 | Loss of silencing activity caused by 5′-terminal modification with D-/L-isonucleotide(isoNA) or locked nucleic acid(LNA) could not be restored by 5′-terminal phosphorylation显示文摘In this study,a series of 5′-phosphorylated siRNAs with D-/L-isonucleotide(isoNA)or locked nucleic acid(LNA)incorporated at the 5′-terminus were synthesized.It was found that after incorporating either isoNA or LNA at the 5′-terminus of the antisense strand or sense strand,the silencing activity of modified strands has been inhibited,which cannot be recovered by phosphorylation at the 5′-terminus;however,the silencing activity of unmodified strand to its own target was increased.This work indicates that the isoNA and LNA modification at 5′-terminus can interfere with the strand selection during the RISC assembling process,and the disturbance of the 5′-phosporylation should not be the only viable mechanism. | HUANG Ye CHEN Zhuo WANG Zhuo LI YaTing CHEN Yue YANG ZhenJun ZHANG LiHe | 2014 | Science China Chemistry2014，57，2： | 1 |
