| 3 | Biomass-derived nitrogen-doped hierarchical porous carbon as efficient sulfur host for lithium–sulfur batteries显示文摘Lithium-sulfur(Li-S) battery is a potential energy storage technology with high energy density and low cost. However, the gap between theoretical expectation and practical performance limits its wide implementation. Herein, we report a nitrogen-doped porous carbon derived from biomass pomelo peel as sulfur host material for Li-S batteries. The hierarchical porous architecture and the polar surface introduced by N-doping render a favorable combination of physical and chemical sulfur confinements as well as an expedite electron/ion transfer, thus contributing to a facilitated and stabilized sulfur electrochemistry. As a result, the corresponding sulfur composite electrodes exhibit an ultrahigh initial capacity of 1534.6 mAh g^-1, high coulombic efficiency over 98% upon 300 cycles, and decent rate capability up to 2 C. This work provides an economical and effective strategy for the fabrication of advanced carbonaceous sulfur host material as well as the significant improvement of Li-S battery performance. | Qinghuiqiang Xiao Gaoran Li Minjie Li Ruiping Liu Haibo Li Pengfei Ren Yue Dong Ming Feng Zhongwei Chen | 2020 | Journal of Energy Chemistry2020，29，5： | 15 |

| 5 | Toxicity of the brominated flame retardant tris-(2,3-dibromopropyl) isocyanurate in zebrafish (Danio rerio)显示文摘Tris-(2,3-dibromopropyl) isocyanurate (TBC) is a heterocyclic brominated flame retardant that was recently detected in the environment in China.TBC is semi-volatile and can accumulate in the lipid of some species,but little is known about its effect on aquatic organisms.We exposed adult zebrafish to 0,0.25,1 and 4mg/L TBC for 28 d and measured the effect on survival,growth,histopathology,hormone levels,enzyme activity,and gene expression.TBC exposure had no effect on survival or growth.We observed significant damage to the liver and gill,including hepatocellular swelling and fatty degeneration in the liver as well as proliferation and edema of epithelial cells in the gills.In addition,exposure to 4mg/L TBC induced proliferation of goblet cells in the intestine of both sexes,acellular areas in the testis,and thinly scattered vitellogenic granules in vitellogenic oocytes.TBC exposure had no effect on the levels of thyroid hormones,testosterone,estradiol,liver superoxide dismutase activity,malondialdehyde content,and brain cholinesterase activity.By contrast,hepatic vitellogenin and cytochrome P4501A gene expression was significantly down-regulated in both male and female zebrafish in response to TBC exposure.Our results suggest that exposure to TBC causes a variety of potential reproductive and endocrine toxic effects. | ZHANG Xu LI Juan CHEN MinJie WU Le ZHANG Chi ZHANG Jie ZHOU QunFang LIANG Yong | 2011 | Chinese Science Bulletin2011，56，15： | 13 |
| 6 | Impact of dissolved organic matter on the photolysis of the ionizable antibiotic norfloxacin显示文摘Norfloxacin(NOR), an ionizable antibiotic frequently used in the aquaculture industry, has aroused public concern due to its persistence, bacterial resistance, and environmental ubiquity.Therefore, we investigated the photolysis of different species of NOR and the impact of a ubiquitous component of natural water — dissolved organic matter(DOM), which has a special photochemical activity and normally acts as a sensitizer or inhibiter in the photolysis of diverse organics; furthermore, scavenging experiments combined with electron paramagnetic resonance(EPR) were performed to evaluate the transformation of NOR in water. The results demonstated that NOR underwent direct photolysis and self-sensitized photolysis via hydroxyl radical(U OH) and singlet oxygen(1O2) based on the scavenging experiments. In addition, DOM was found to influence the photolysis of different NOR species, and its impact was related to the concentration of DOM and type of NOR species. Photolysis of cationic NOR was photosensitized by DOM at low concentration, while zwitterionic and anionic NOR were photoinhibited by DOM, where quenching of U OH predominated according to EPR experiments, accompanied by possible participation of excited triplet-state NOR and1O2. Photo-intermediate identification of different NOR species in solutions with/without DOM indicated that NOR underwent different photodegradation pathways including dechlorination, cleavage of the piperazine side chain and photooxidation, and DOM had little impact on the distribution but influenced the concentration evolution of photolysis intermediates. The results implied that for accurate ecological risk assessment of emerging ionizable pollutants, the impact of DOM on the environmental photochemical behavior of all dissociated species should not be ignored. | Chen Liang Huimin Zhao Minjie Deng Xie Quan Shuo Chen Hua Wang | 2015 | Journal of Environmental Sciences2015，27，1： | 11 |

| 8 | Process Control and Optimization for Heterologous Protein Production by Methylotrophic Pichia pastoris显示文摘The methylotrophic yeast Pichia pastoris is a highly successful system for production of a variety of heterologous proteins due to its unique features/abilities for effective protein expression, and tremendous efforts have been made to increase heterologous protein productivity by P. pastoris in recent years. When new engineered yeast strains are constructed and are ready to use for industrial protein production, process control and optimization techniques should be applied to improve the fermentation performance in the following aspects: (1) increase recombinant cell concentrations in fermentor to high density during growth phase; (2) effectively induce heterologous proteins by enhancing/stabilizing titers or concentrations of the proteins during induction phase; (3) decrease operation costs by relieving the working loads of heat-exchange and oxygen supply. This article reviews and discusses the key and commonly used techniques in heterologous protein production by P. pastoris, with the focus on optimizations of fermentation media and basic operation conditions, development of optimal glycerol feeding strategies for achieving high density cultivation of P. pastoris and effective heterologous protein induction methods by regulating specific growth rate, methanol concentration, temperatures, mixture ratio of multi-carbon substrates, etc. Metabolic analysis for recombinant protein production by P. pastoris is also introduced to interpret the mechanism of sub-optimal heterologous protein production and to explore further optimal expression methods. | GAO Minjie SHI Zhongping | 2013 | Chinese Journal of Chemical Engineering2013，21，2： | 10 |

| 10 | Choice for graphene as conductive additive for cathode of lithium-ion batteries显示文摘Graphene is a promising conductive additive for the lithium-ion batteries(LIBs) and shows great potential especially with its fast development of the large scale fabrication technology. This work has explored the influence of the incorporation of graphenes prepared by three typical methods on the electrochemical performance of the LiCoO_2-based cathode focusing on the choice for the effective graphene as conductive additive for the cathode of LIBs. Through the comparison of the intrinsic characteristics of graphenes and the electrochemical performance of electrodes with graphene, it is found that graphene with low disorder degree and large size is not suitable for LiCoO_2 cathodes as conductive additive. Conversely, the graphene with oxygen functional groups, relatively low surface area and proper size displays much better electrochemical performance when it is used as conductive additive. This work also demonstrates the transmission mechanism for different graphenes as conductive additives in the LiCoO_2 materials, and further reveals that the conductivity of graphene is not the only factor as conductive additives, surface chemistry and sheet size of the graphene are also essential factors which greatly influence the electrochemical performance of electrode. In addition, when combined with Super P, only 1% graphene is enough to construct an efficient conductive network in the electrode. This study also gives a new sight on the practical application of graphene as conductive additive for high performance LIBs. | Ying Shi Lei Wen Songfeng Pei Minjie Wu Feng Li | 2019 | Journal of Energy Chemistry2019，28，3： | 10 |
| 11 | A 600-year flood history in the Yangtze River drainage:Comparison between a subaqueous delta and historical records显示文摘Based on grain size analysis and high-resolution elemental scanning of core YD0901,taken from the subaqueous Yangtze River delta,a 600-year flood history was reconstructed for the Yangtze River drainage system.Zr/Rb ratios were chosen as a proxy for Yangtze River floods.Zr resides mainly in the coarse-grained minerals,and Rb is found in the fine-grained minerals.When floods occur,the discharge of the Yangtze River increases,which carries more coarse-grained minerals into the East China Sea.Therefore,deposition of coarse-grained minerals significantly increases relative to fine-grained minerals on the subaqueous delta,and subsequently the Zr/Rb ratios also increase.The higher the Zr/Rb peaks,the greater number of coarse particles deposited by saltation processes.Zr/Rb peaks correlate very well with historical records for Yangtze River floods.Especially at about AD 1870,the Zr/Rb ratio reached a maximum value over the last 600 years,which is consistent with 'the extreme flood event' in the upper and middle reaches of the Yangtze River in AD 1870,as indicated in the historical records.Results show that floods have occurred at a relatively high frequency over the last 600 years,which is consistent with historical records when,during the Ming-Qing Dynasty,floods occurred once every 4 years.In addition,spectral analysis of the Zr/Rb ratio showed that there is close link between the Yangtze River floods and ENSO intensity. | WANG MinJie ZHENG HongBo XIE Xin FAN DaiDu YANG ShouYe ZHAO QuanHong WANG Ke | 2011 | Chinese Science Bulletin2011，56，2： | 9 |

| 14 | Iron and lead ion adsorption by microbial flocculants in synthetic wastewater and their related carbonate formation显示文摘Although microbial treatments of heavy metal ions in wastewater have been studied, the removal of these metals through incorporation into carbonate minerals has rarely been reported. To investigate the removal of Fe3+and Pb2+, two representative metals in wastewater, through the precipitation of carbonate minerals by a microbial flocculant(MBF) produced by Bacillus mucilaginosus. MBF was added to synthetic wastewater containing diferent Fe3+and Pb2+concentrations, and the extent of flocculation was analyzed. CO2 was bubbled into the mixture of MBF and Fe3+/Pb2+to initiate the reaction. The solid substrates were analyzed via X-ray difraction, transmission electron microscopy and energy dispersive spectroscopy. The results showed that the removal efciency decreased and the MBF adsorption capacity for metals increased with increasing heavy metal concentration. In the system containing MBF, metals(Fe3+ and Pb2+), and CO2, the concentrated metals adsorbed onto the MBF combined with the dissolved CO2, resulting in oversaturation of metal carbonate minerals to form iron carbonate and lead carbonates. These results may be used in designing a method in which microbes can be utilized to combine CO2 with wastewater heavy metals to form carbonates, with the aim of mitigating environmental problems. | Minjie Yao Bin Lian Hailiang Dong Jianchao Hao Congqiang Liu | 2013 | Journal of Environmental Sciences2013，25，12： | 7 |
| 15 | Involvement of C2H2 zinc finger proteins in the regulation of epidermal cell fate determination in Arabidopsis显示文摘Cell fate determination is a basic developmental process during the growth of multicellular organisms.Trichomes and root hairs of Arabidopsis are both readily accessible structures originating from the epidermal cells of the aerial tissues and roots respectively, and they serve as excellent models for understanding the molecular mechanisms controlling cell fate determination and cell morphogenesis. The regulation of trichome and root hair formationis a complex program that consists of the integration of hormonal signals with a large number of transcriptional factors, including MYB and b HLH transcriptional factors.Studies during recent years have uncovered an important role of C2H2 type zinc finger proteins in the regulation of epidermal cell fate determination. Here in this minireview we briefly summarize the involvement of C2H2 zinc finger proteins in the control of trichome and root hair formation in Arabidopsis. | An Yan Minjie Wu Yongqin Zhao Aidong Zhang Bohan Liu John Schiefelbein Yinbo Gan | 2014 | Journal of Integrative Plant Biology2014，56，12： | 7 |
| 16 | Genomic insights into the fast growth of paulownias and the formation of Paulownia witches' broom显示文摘Paulownias are among the fastest growing trees in the world,but they often suffer tremendous loss of wood production due to infection by Paulownia witches'broom(PaWB)phytoplasmas.In this study,we have sequenced and assembled a high-quality nuclear genome of Paulownia fortunei,a commonly cultivated paulownia species.The assembled genome of P.fortunei is 511.6 Mb in size,with 93.2%of its sequences anchored to 20 pseudo-chromosomes,and it contains 31985 protein-coding genes.Phylogenomic analyses show that the family Paulowniaceae is sister to a clade composed of Phrymaceae and Orobanchaceae.Higher photosynthetic efficiency is achieved by integrating C3 photosynthesis and the crassulacean acid metabolism pathway,which may contribute to the extremely fast growth habit of paulownia trees.Comparative transcriptome analyses reveal modules related to cambial growth and development,photosynthesis,and defense responses.Additional genome sequencing of PaWB phytoplasma,combined with functional analyses,indicates that the effector PaWB-SAP54 interacts directly with Paulownia PfSPLa,which in turn causes the degradation of PfSPLa by the ubiquitin-mediated pathway and leads to the formation of witches'broom.Taken together,these results provide significant insights into the biology of paulownias and the regulatory mechanism for the formation of PaWB. | Yabing Cao Guiling Sun Xiaoqiao Zhai Pingluo Xu Liming Ma Minjie Deng Zhenli Zhao Haibo Yang Yanpeng Dong Zhonghai Shang Yujie Lv Lijun Yan Haifang Liu Xibing Cao Bingbing Li Zhe Wang Xiaogai Zhao Haiyan Yu Fan Wang Wen Ma Jinling Huang Guoqiang Fan | 2021 | Molecular Plant2021，14，10： | 7 |
| 17 | Angelica tenuissima Nakai Ameliorates Cognitive Impairment and Promotes Neurogenesis in Mouse Model of Alzheimer's Disease显示文摘Objective: To research Angelica tenuissima Nakai(ATN) for use in novel Alzheimer's disease(AD) therapeutics. Methods: The effect of a 30% ethanol extract of ATN(KH032) on AD-like cognitive impairment and neuropathological and neuroinflammatory changes induced by bilateral intracerebroventricular injections of β-amyloid(Aβ) peptide(Aβ_(1-42)) was investigated. Male C57 Bl/6 mice were randomly divided into 4 groups, 10 in each group. KH032-treated groups were administrated with a low or high dose of KH032(50 and 200 mg/kg, respectively), intragastrically for 16 days; distilled water was applied in the sham and negative groups. Open field test, Y maze and Morris water maze test were used for behavior test and cognitive ability. In addition, the neuroprotective effects of KH032 in Aβ_(1-42)-infused mice on the histopathological markers [neuronspecific nuclear protein(Neu N), Aβ1-42] of neurodegeneration were examined. The levels of glial fibrillary acidic protein(GFAP), Neu N, phosphorylation extracellular signal-regulated kinase(ERK)/ERK, brain-derived neurotrophic factor(BDNF), phosphorylation c AMP response element-binding(CREB)/CREB protein expression were measured by Western blot. Results: KH032 treatment ameliorated cognitive impairments, reduced the overexpression of Aβ_(1-42), and inhibited neuronal loss and neuroinflammatory response in the Aβ_(1-42)-infused mice. Moreover, KH032 treatment enhanced BDNF expression levels in the hippocampus. Finally, KH032 treatment increased phosphorylation of ERK1/2 and CREB, vital for ERK-CREB signaling. Conclusions: KH032 attenuated cognitive deficits in the Aβ_(1-42)-infused mice by increasing BDNF expression and ERK1/2 and CREB phosphorylation and inhibiting neuronal loss and neuroinflammatory response, suggesting that KH032 has therapeutic potential in neurodegenerative disorders such as AD. | Minji Choi Younghyurk Lee Seung-Hun Cho | 2018 | Chinese Journal of Integrative Medicine2018，24，5： | 7 |

The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations. | Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 7 |
| 20 | Chemical vapor deposition of monolayer WS2 nano- sheets on Au foils toward direct application in hydrogen evolution显示文摘Monolayer tungsten disulfide (WS2), a typical member of the semiconducting transition metal dichalcogenide family has drawn considerable interest because of its unique properties. Intriguingly the edge of WS2 exhibits an ideal hydrogen binding energy which makes WS2 a potential alternative to Pt-based electrocatalysts for the hydrogen evolution reaction (HER). Here, we demonstrate for the first time the successful synthesis of uniform monolayer WS2 nanosheets on centimeter- scale Au foils using a facile, low-pressure chemical vapor deposition method. The edge lengths of the universally observed triangular WS2 nanosheets are tunable from -100 to N1,000 nm. The WS2 nanosheets on Au foils featuring abundant edges were then discovered to be efficient catalysts for the HER, exhibiting a rather high exchange current density of -30.20 μA/cm2 and a small onset potential of Nl10 mV. The effects of coverage and domain size (which correlate closely with the active edge density of WS2) on the electrocatalytic activity were investigated. This work not only provides a novel route toward the batch-production of monolayer WS2 via the introduction of metal foil substrates but also opens up its direct application for facile HER. | Yanshuo Zhang Jianping Shi Gaofeng Han Minjie Li Qingqing Ji Donglin Ma Yu Zhang Cong Li Xingyou Lang Yanfeng Zhang Zhongfan Liu | 2015 | Nano Research2015，8，9： | 7 |
