| 1 | Effect of rGO Coating on Interconnected Co_3O_4 Nanosheets and Improved Supercapacitive Behavior of Co_3O_4/rGO/NF Architecture显示文摘In this study, the effect of reduced graphene oxide(rGO) on interconnected Co_3O_4 nanosheets and the improved supercapacitive behaviors is reported. By optimizing the experimental parameters, we achieved a specific capacitance of ~1016.4 F g^(-1) for the Co_3O_4/rGO/NF(nickel foam) system at a current density of 1 A g^(-1). However, the Co_3O_4/NF structure without rGO only delivers a specific capacitance of ~520.0 F g^(-1)at the same current density. The stability test demonstrates that Co_3O_4/rGO/NF retains ~95.5% of the initial capacitance value even after 3000 charge–discharge cycles at a high current density of 7 A g^(-1). Further investigation reveals that capacitance improvement for the Co_3O_4/rGO/NF structure is mainly because of a higher specific surface area(~87.8 m^2g^(-1))and a more optimal mesoporous size(4–15 nm) compared to the corresponding values of 67.1 m^2g^(-1) and 6–25 nm,respectively, for the Co_3O_4/NF structure. rGO and the thinner Co_3O_4 nanosheets benefit from the strain relaxation during the charge and discharge processes, improving the cycling stability of Co_3O_4/rGO/NF. | Tinghui Yao Xin Guo Shengchun Qin Fangyuan Xia Qun Li Yali Li Qiang Chen Junshuai Li Deyan He | 2017 | Nano-Micro Letters2017，9，4： | 8 |
| 2 | Ultraviolet Photoconductance of a Single Hexagonal WO_(3) Nanowire显示文摘The ultraviolet (UV) photoconductance properties of a single hexagonal WO_(3) nanowire have been studied systematically. The conductance of WO_(3) nanowires is very sensitive to ultraviolet B light and a field-effect transistor (FET) nanodevice incorporating a single WO_(3) nanowire exhibits excellent sensitivity, reversibility, and wavelength selectivity. A high photoconductivity gain suggests that WO_(3) nanowires can be used as the sensing element for UV photodetectors. Measurements under UV light in vacuum show that the adsorption and desorption of oxygen molecules on the surface of the WO_(3) nanowire can significantly influence its photoelectrical properties. The WO_(3) nanowires have potential applications in biological sensors, optoelectronic devices, optical memory, and other areas. | Kai Huang Qing Zhang Feng Yang Deyan He | 2010 | Nano Research2010，3，4： | 7 |

| 4 | Responses of soil microbial communities and functions associated with organic carbon mineralization to nitrogen addition in a Tibetan grassland显示文摘Alpine grasslands with a high soil organic carbon(SOC)storage on the Tibetan Plateau are experiencing rapid climate warming and anthropogenic nitrogen(N)deposition;this is expected to substantially increase the soil N availability,which may impact carbon(C)cycling.However,little is known regarding how N enrichment influences soil microbial communities and functions relative to C cycling in this region.We conducted a 4-year field experiment on an alpine grassland to evaluate the effects of four different rates of N addition(0,25,50,and 100 kg N ha^-1 year^-1)on the abundance and community structure(phospholipid fatty acids,PLFAs)of microbes,enzyme activities,and community level physiological profiles(CLPP)in soil.We found that N addition increased the microbial biomass C(MBC)and N(MBN),along with an increased abundance of bacterial PLFAs,especially Gram-negative bacterial PLFAs,with a decreasing ratio of Gram-positive to Gram-negative bacteria.The N addition also stimulated the growth of fungi,especially arbuscular mycorrhizal fungi,reducing the ratio of fungi to bacteria.Microbial functional diversity and activity of enzymes involved in C cycling(β-1,4-glucosidase and phenol oxidase)and N cycling(β-1,4-N-acetyl-glucosaminidase and leucine aminopeptidase)increased after N addition,resulting in a loss of SOC.A meta-analysis showed that the soil C/N ratio was a key factor in the response of oxidase activity to N amendment,suggesting that the responses of soil microbial functions,which are linked to C turnover relative to N input,primarily depended upon the soil C/N ratio.Overall,our findings highlight that N addition has a positive influence on microbial communities and their associated functions,which may reduce soil C storage in alpine grasslands under global change scenarios. | Ruyi LUO Jiafa LUO Jianling FAN Deyan LIU Jin-Sheng HE Nazia PERVEEN Weixin DING | 2020 | Pedosphere2020，30，2： | 3 |
| 5 | Preparation and electrochemical performance of MWCNTs@MnO_2 nanocomposite for lithium ion batteries显示文摘Tubular nanocomposite with interconnected MnO2 nanoflakes coated on MWCNTs(MWCNTs@MnO2)was fabricated by an aqueous solution method at 80°C.Scanning electron microscopy,X-ray diffraction and galvanostatic charge-discharge tests were used to characterize the structures and electrochemical performances of the as-prepared nanocomposite.The capacity reaches 1233.6 mA h g-1 at a current density of 100 mA g-1 for the first discharge,and it can still maintain a capacity of 633.1mA h g-1 after 100 charge-discharge cycles.The results show that MWCNTs with good electrical conductivity as anchors of MnO2 can provide fast electron transport channels for MnO2 in the electrochemical reactions,and the as-prepared MWCNTs@MnO2 nanocomposite is a potential anode material for lithium ion batteries. | LIU YingQi LI XiuWan WEI ZhiWei ZHANG LiPing WEI XiuCheng HE DeYan | 2014 | Science China(Technological Sciences)2014，57，6： | 2 |
| 6 | Yield-scaled nitrous oxide emissions from nitrogen-fertilized croplands in China: A meta-analysis of contrasting mitigation scenarios显示文摘Nitrogen(N) losses in cropland resulting from the application of synthetic fertilizers decrease crop productivity and exacerbate environmental pollution.Mitigation measures, such as reduction in N fertilizer application rates, can have unintentional adverse effects on crop yield. We conducted a meta-analysis of soil N_(2)O emissions from agricultural fields across China under contrasting mitigation scenarios as a novel approach to identify the most effective strategy for the mitigation of emissions of N_(2)O derived from N fertilizer use in China. Current standard agricultural practice was used as a baseline scenario(BS), and 12 potential mitigation scenarios(S1–S12) were derived from the available literature and comprised single and combinations of management scenarios that accounted for crop yield. Mitigation scenarios S6(nitrification inhibitor 3,4-dimethylpyrazole phosphate) and S11(20% reduction in N application rate plus nitrification inhibitor dicyandiamide) in maize, rice, and wheat crops led to an average 56.0% reduction in N_(2)O emissions at the national level, whereas scenario S4(nitrification inhibitor dicyandiamide) led to yield optimization, with a 14.0% increase for maize and 8.0% increase for rice as compared to the BS. Implementation of these most effective mitigation scenarios(S4, S6, and S11) might help China, as a signatory to the 2015 United Nations Framework Convention on Climate Change(Paris Agreement), to achieve a 30% reduction in N_(2)O emissions by 2030. | Garba ALIYU Jiafa LUO Hong J.DI Deyan LIU Junji YUAN Zengming CHEN Tiehu HE Weixin DING | 2021 | Pedosphere2021，31，2： | 2 |

| 8 | Kinetic Monte Carlo simulation of film morphologies at the initial stages显示文摘The morphologies at the initial stages of thin film growth were studied by using Kinetic Monte Carlo techniques.A more efficient model was used to calculate the activity energy.The model involves incident atom attachment,diffusion,detachment from the surface,detached atom returning,and dimer diffusion.We edited a set of software of the model and simulated the surface morphologies by the principle of computer graphics.It is shown that the nucleuses formed at the initial stages and the surface morphologies at high temperatures are very different from those at low temperatures.The later surface growth depends on the nucleuses at the initial stages.The mechanism results from the atom thermal movement,the temperature determines the diffusion ability,and the deposition rate determines the diffusion time. | ZHENG XiaoPing ZHANG PeiFeng HE DeYan LI Lian | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，1： | 1 |

| 16 | Facile synthesis of NiMn2S4 nanoflakes on nickel foam for high-performance aqueous asymmetric supercapacitors显示文摘Supercapacitors display promising electrochemical performance with high power density and excellent cycle stability.However,their low energy density limits their advancement in a broader range of applications.To enhance their energy density,we proposed self-assembled spinel NiMn2S4nanoflakes grown on nickel foam which we successfully prepared by a facile hydrothermal method.The NiMn2S4electrode delivers a high capacitance of 2096.7 F g^(-1)at 1.0 A g^(-1),with an exceptional rate capability(~720.6 F g^(-1)at a very high current density of 100 A g^(-1))and good cycle stability(~85.1%retention of the initial capacitance after 7000 cycles with the Coulombic efficiency around 100%).The as-fabricated asymmetric supercapacitors based on NiMn2S4nanoflakes//active carbon demonstrate an energy density of 73.6 W h kg^(-1)at 800.5 W kg^(-1)and adequate cycling performance of~84.6%capacitance retention at 15 A g^(-1)after 10000 cycles.The results reveal that the nanostructured NiMn2S4is an excellent electrode material for high-performance energy storage applications. | ADIL Emin LI YaLi GAO Zhe DONG YunXia LI DongHao CHEN YongChao FU YuJun HE DeYan LI JunShuai | 2024 | Science China(Technological Sciences)2024，67，2： | 0 |
| 17 | Discovery of a Potent Botulinum Neurotoxin A Inhibitor ZM299 with Effective Protections in Botulism Mice显示文摘Botulinum neurotoxins serotype A(BoNT/A)is the deadliest toxins known to humans and the'Category A'agent for bioterrorism.Over the past 20 years,significant efforts have been put forth to develop effective inhibitors of BoNT/A.Unfortunately,few identified inhibitors possess noteworthy efficacy against BoNT/A in vivo.Here,we performed a high-throughput virtual screening based on the structure-based docking simulations and found a novel potent scaffold 2-thionicotinate that inhibits the BoNT/A light chain(LC).We then synthesized and optimized a novel series of 2-thionicotinate derivatives and comprehensively evaluated their activity against BoNT/A in vitro and in vivo.An optimized compound ZM299 effectively exhibits anti-BoNT/A activity in primary neurons and displayed remarkably therapeutic efficacy against BoNT/A in vivo,which could raise the survival rate of intoxicated mice to 100%(12/12)after lethal doses of BoNT/A exposures.These findings demonstrate that 2-thionicotinates is a promising scaffold for producing more effective anti-BoNT/A analogs,and compound ZM299 is worthy of further preclinical evaluation as a drug candidate for the treatment of botulism. | Jianxin Wang Yuelin Wu Deyan Luo Chunlin Zhuang Nianzhi Ning Yanming Zhang Zhili He Jie Gao Zhanying Hong Xiguo Xv Wannian Zhang Tao Li Zhenyuan Miao Hui Wang | 2022 | Chinese Journal of Chemistry2022，40，3： | 0 |
| 18 | Improved comprehensive performance of CsPbI_(2) Br perovskite solar cells by modifying the photoactive layers with carbon nanodots显示文摘Introducing additives into perovskite layers is an effective method to enhance the power conversion efficiency(PCE)and operation stability of perovskite solar cells(PSCs).Herein,we reported an addition of carbon nanodots(CNDs)into the CsPbI_(2) Br photoactive layer to boost performance of the related PSCs.It is found that the trap density can be notably suppressed,and the crystallinity can be enhanced after introducing CNDs with an optimal quantity.The PSC with 1.0 wt%addition of CNDs delivers a notable improved average PCE of 13.77%(the highest PCE:14.69%)from that of 12.14%for the control device without CND addition.Moreover,the CND-added CsPbI 2 Br PSCs exhibit superior stability,i.e.,~86% retention of the initial PCE after 160 h aging in air with the humidity of 20%-30%,to the control device. | Yanzhou Wang Caidong Xie Xincheng Yao Qiulu Chen Weining Liu Yujun Fu Qiming Liu Junshuai Li Yali Li Deyan He | 2022 | Journal of Materiomics2022，8，2： | 0 |
| 19 | Enhancement of photoelectric performance for CsPbI2Br solar cells by the synergistic effect of binary additives显示文摘CsPbI_(2)Br-based perovskite solar cells(PSCs)have attracted much attention because of their excellent phase stability and appropriate bandgap.However,numerous defects of undercoordinated ions or mobile species are the sites of carrier nonradiative recombination,causing a low power conversion efficiency(PCE).In this work,NaCl and nitrogen-doped graphene quantum dots(N-GQDs)as binary additives are introduced into perovskite precursor to obtain high-quality photoactive films.Chloride ion(Cl^(-))is incorporated into perovskite due to the same physical and chemical properties as bromine(Br^(-)),that align the energy level of CsPbI_(2)Br,decrease the energy barrier between perovskite and P3HT to promote carrier transport and extraction,hence result in the reduced energy loss.Meanwhile,because of its good conductivity,N-GQDs at grain boundaries can rapidly conduct photogenerated electrons to SnO_(2),suppressing carrier recombination at grain boundaries.Furthermore,the trap state density of the CsPbI_(2)Br film with binary additives is reduced,which could prolong the carrier lifetime,and improve surface morphology.As a result,a PCE of 15.37%for CsPbI_(2)Br PSCs with binary additives is obtained,which shows~22.76%relative increment compare with the pristine PSCs.Therefore,a simple and convenient optimization strategy of binary additives for PSCs is proposed in this work. | Qiulu Chen Like Lin Yanzhou Wang Zhe Gao Yujun Fu Qiming Liu Junshuai Li Deyan He | 2023 | Journal of Materiomics2023，9，1： | 0 |
