| 1 | Ab initio prediction and characterization of phosphorene-like SiS and SiSe as anode materials for sodium-ion batteries显示文摘In this work, a density functional theory(DFT) based first-principles study is carried out to investigate the potential of phosphorene-like SiS and SiSe monolayers as anode materials for sodium-ion(Na-ion) batteries. Results show that both SiS and SiSe have large adsorption energies towards single Na atom of 0.94 and 0.43 eV, owing to the charge transfers from Na to SiS or SiSe. In addition, it is found that the highest Na concentration for both SiS and SiSe is x = 1 with the chemical formulas of Na SiS and Na SiSe, corresponding to the high theoretical specific capacities for Na storages of 445.6 and 250.4 m Ah g^(-1), respectively. Moreover, Na diffusions are very fast and show strong directional behaviors on SiS and SiSe monolayers, with the energy barriers of only 0.135 and 0.158 eV, lower than those of conventional anode materials for Na-ion batteries such as Na_2Ti_3O_7(0.19 eV) and Na_3Sb(0.21 eV). Finally,although SiS and SiSe show semiconducting behaviors, they transform to metallic states after adsorbing Na atoms, indicating enhanced electrical conductivity during battery cycling. Given these advantages, it is expected that both SiS and SiSe monolayers are promising anode materials for Na-ion batteries, and in principle, other Na-based batteries as well. | Haoran Jiang Tianshou Zhao Yuxun Ren Ruihan Zhang Maochun Wu | 2017 | Science Bulletin2017，62，8： | 6 |
| 2 | A Li-S battery with ultrahigh cycling stability and enhanced rate capability based on novel ZnO yolk-shell sulfur host显示文摘Currently,lithium-sulfur(Li-S)batteries still suffer from fast capacity decay,poor coulombic efficiency(CE)and short cycling lifespan,which result from the severe shuttle effect issue caused by high solubility and rapid diffusion of lithium polysulfides(Li PSs)in organic electrolytes.Here,yolk-shell zinc oxide(YSZn O)spheres are synthesized and for the first time,applied as a host for Li-S batteries to tackle this challenge.The polar Zn O exhibits high chemical anchoring ability toward Li PSs while the unique yolk-shell structure not only provides an additional physical barrier to Li PSs but also enables much more uniform sulfur distribution,thus significantly suppressing Li PSs shuttling effect meanwhile promoting sulfur conversion reactions.As a result,the YS-Zn O enables the Li-S battery to display an initial specific capacity of1355 m Ah g^(-1) and an outstanding capacity retention capability(~89.44%retention rate)even after 500 cycles with the average CE of~99.46%at the current of 0.5 C.By contrast,the capacity of conventional-Zn O-nanoparticles based battery severely decays to 472 m Ah g^(-1) after cycling for 500 times.More impressively,the S/YS-Zn O based Li-S battery can maintain a low decay rate of 0.040%every cycle and high average CE of 98.82%over 1000 cycles at 3 C. | Ruihan Zhang Maochun Wu Xinzhuang Fan Haoran Jiang Tianshou Zhao | 2021 | Journal of Energy Chemistry2021，30，4： | 5 |
| 3 | Evaluation index system of shared energy storage market towards renewable energy accommodation scenario:A China’s Qinghai province context显示文摘With the ever-increased installed capacity of renewable energy generation units in a power system,the so-called shared energy storage(SES),a novel business model under the umbrella of the shared economy principle,has the potential to play an essential role in the accommodation of renewable energy generation.However,unified evaluation standards and methods,which can help decision-makers analyze the performance of the SES market,are still not available.In this paper,an evaluation index system of the SES market is designed based on the trading rules of China’s Qinghai province and the structure-conduct-performance(SCP)analytical model.Moreover,the definition and characteristics of the indices,which can show the performance of the SES market from different perspectives,are given.Furthermore,the ideal cases are presented as the evaluation benchmark based on the development expectation of the SES market,and the analytic hierarchy process(AHP)and the technique for order preference by similarity to an ideal solution(TOPSIS)are applied to evaluate the SES market comprehensively.Finally,a case study based on actual data of the SES trading pilot project in Qinghai shows that the evaluation index system can reflect the operation status,existing problems and influencing factors of the SES market. | Baomin Fang Weiqiang Qiu Maochun Wang Wei Zhou Zhenzhi Lin Fushuan Wen | 2022 | Global Energy Interconnection2022，5，1： | 5 |
| 4 | Optimization on Production Key Factors of Microbial Fermented Feed and Analysis on Composition Variation During Fermentation显示文摘[Objective] In order to study the production key factors of microbial fermented feed and the composition variation during fermentation. [Methods]Water,temperature,energy and protein were selected to study the effects on microbial fermented feed. And the fermentation conditions were optimized. Changes on nutrient composition during fermentation were determined and analyzed. [Result] Test results showed that feed formula with high sugar content,low protein,34%-36% water content,high fermentation temperature was more conducive to the production and actual production needs of fermentation strains. During the fermentation,strains showed interactions,test tended to be completed at the 144^(th)h after the fermentation,and number of lactic acid bacteria reached the peak of 1. 86 × 10~9 strain/g,contents of lactic acid could even reach 0. 89%. As time prolonged,contents of total energy,fiber and isothiocyanate gradually reduced,while contents of water and protein increased slightly. Contents of vitamin were stable,which in an order of V_B> V_E> V_K> V_A> V_D. Composition of amino acids showed an better change,contents of glutamic acid and proline decreased slowly,while contents of glycine and phenylalanine increased slowly. [Conclusion]High quality microbial fermentation feed could improve the palatability and safety of feed and keep the intestinal balance of livestock and poultry,which had broad application prospect. | Lin Biaosheng Luo Jian Li Yiming He Yuqin Luo Maochun Yang Xiaoyan | 2017 | Animal Husbandry and Feed Science2017，9，3： | 4 |
| 5 | 3D metal-organic frameworks based on lanthanide-seamed dimeric pyrogallol[4]arene nanocapsules显示文摘Two novel 3D metal-organic frameworks(MOFs)with cds network,{[Me NH_3]_7[Ln_8(Pg C_2)_2(H_2O)_y(HCOO)_7]}_n·x(Solvent)(FJI-Y4,FJI=Fujian Institute,Ln=Gd,y=12;FJI-Y5,Ln=Dy,y=11;Pg C_2=C-ethylpyrogallol[4]arene),based on unprecedented dimeric pyrogallol[4]arene-based Ln_8metal-organic nanocapsule(MONC)supramolecular building blocks and formate linkers,have been prepared under solvothermal conditions.To our best of knowledge,they present not only the first two examples of 3D hierarchical structures constructed from MONCs in metal-pyrogallol[4]arene system,but also the first two examples of MOFs based on lanthanide MONCs.Remarkably,the inner cavity volume of the Ln_8capsule in FJI-Y4 and FJI-Y5 is approximately151?~3,which is larger than those found in previous transition metal-seamed dimeric Pg C_n-based MONCs.Magnetic investigation on FJI-Y4 suggests a significant magnetocaloric effect(23.97 J kg^(-1)K^(-1),ΔH=7 T,2.5 K),while FJI-Y5 exhibits slow relaxation of the magnetization. | Kongzhao Su Mingyan Wu Wenjing Wang Mi Zhou Daqiang Yuan Maochun Hong | 2018 | Science China Chemistry2018，61，6： | 2 |

| 7 | Targeting macrophagic SHP2 for ameliorating osteoarthritis via TLR signaling显示文摘Osteoarthritis(OA),in which M1 macrophage polarization in the synovium exacerbates disease progression,is a major cause of cartilage degeneration and functional disabilities.Therapeutic strategies of OA designed to interfere with the polarization of macrophages have rarely been reported.Here,we report that SHP099,as an allosteric inhibitor of src-homology 2-containing protein tyrosine phosphatase 2(SHP2),attenuated osteoarthritis progression by inhibiting M1 macrophage polarization.We demonstrated that M1 macrophage polarization was accompanied by the overexpression of SHP2 in the synovial tissues of OA patients and OA model mice.Compared to wild-type(WT)mice,myeloid lineage conditional Shp2 knockout(c KO)mice showed decreased M1 macrophage polarization and attenuated severity of synovitis,an elevated expression of cartilage phenotype protein collagen II(COL2),and a decreased expression of cartilage degradation markers collagen X(COL10)and matrix metalloproteinase3(MMP3)in OA cartilage.Further mechanistic analysis showed that SHP099 inhibited lipopolysaccharide(LPS)-induced Toll-like receptor(TLR)signaling mediated by nuclear factor kappa B(NF-κB)and PI3K—AKT signaling.Moreover,intra-articular injection of SHP099 also significantly attenuated OA progression,including joint synovitis and cartilage damage.These results indicated that allosteric inhibition of SHP2 might be a promising therapeutic strategy for the treatment of OA. | Ziying Sun Qianqian Liu Zhongyang Lv Jiawei Li Xingquan Xu Heng Sun Maochun Wang Kuoyang Sun Tianshu Shi Zizheng Liu Guihua Tan Wenqiang Yan Rui Wu Yannick Xiaofan Yang Shiro Ikegawa Qing Jiang Yang Sun Dongquan Shi | 2022 | Acta Pharmaceutica Sinica B2022，12，7： | 2 |

| 10 | A critical Trudinger-Moser inequality involving a degenerate potential and nonlinear Schrodinger equations显示文摘The classical critical Trudinger-Moser inequality in R^(2)under the constraint∫_(R_(2))(|▽u|^(2)+|u|^(2))dx≤1 was established through the technique of blow-up analysis or the rearrangement-free argument:for anyτ>0,it holds that sup u∈H^(1)(r^(2)fR^(2)(τ|U|^(2)+|▽u|^(2)dx≤1∫_(R^(2)(E^4π|u|^(2)-1)dx≤C(τ)<+∞)))and 4πis sharp.However,if we consider the less restrictive constraint∫_(R_(2))(|▽u|^(2)+|u|^(2))dx≤1,where V(x)is nonnegative and vanishes on an open set in R^(2),it is unknown whether the sharp constant of the Trudinger-Moser inequality is still 4π.The loss of a positive lower bound of the potential V(x)makes this problem become fairly nontrivial.The main purpose of this paper is twofold.We will first establish the Trudinger-Moser inequality sup u∈H^(1)(r^(2)fR^(2)(τ|U|^(2)+|▽u|^(2)dx≤1∫_(R^(2)(E^4π|u|^(2)-1)dx≤C(τ)<+∞)))when V is nonnegative and vanishes on an open set in R^(2).As an application,we also prove the existence of ground state solutions to the following Sciridinger equations with critical exponeitial growth:-Δu+V(x)u=f u)in R^(2),(0.1)where V(x)≥0 and vanishes on an open set of R^(2)and f has critical exponential growth.Having a positive constant lower bound for the potential V(x)(e.g.,the Rabinowitz type potential)has been the standard assumption when one deals with the existence of solutions to the above Schrodinger equations when the nonlinear term has the exponential growth.Our existence result seems to be the first one without this standard assumption. | Lu Chen Guozhen Lu Maochun Zhu | 2021 | Science China Mathematics2021，64，7： | 1 |
| 11 | On the effect of injection of gas in the numerical simulation of accretion flows显示文摘We investigate the effects of various ways of injection of gas at the outer boundary in the numerical simulations of non-viscous accretion flows.We study three models.In Model A,we inject material around the equatorial plane.In Models B and C,fullrange θ injection is used(we employ spherical coordinates).In all three models,the injected material has the same density distribution with polar angle θ.From the equatorial region to the polar regions,angular momentum of the injected material of Model B decreases faster than that in Model C.For all of the models,after a transient episode of infall at the beginning of the simulations,the gas piles up in the equatorial regions outside the black hole and forms a thick torus bounded by a centrifugal barrier.We find that the accretion rates of Models B and C are more than ten times higher than that in Model A.In Model A,there is weak accretion only in the torus and outflows are found on the surface of the torus.In Model B,we find strong inflows on the surface of its torus,and the accretion in the torus is weak.In Model C,strong inflows also occur on the surface of its torus,but the accretion regions are narrower and there are strong outflows in its torus.In all of our models,the time-averaged density,pressure and angular momentum in the equatorial region can be described by a radial power law,with P ∝r-3/2,P ∝r-2 and l∝r0. | BU DeFu,YUAN Feng,WU MaoChun & YANG XiaoHong Key Laboratory for Research in Galaxies and Cosmology,Shanghai Astronomical Observatory,Chinese Academy of Sciences,Shanghai 200030,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，S1： | 1 |
| 12 | A Nonlinear Optical Switchable Sulfate of Ultrawide Bandgap显示文摘Nonlinear optical(NLO)switchable materials have attracted intense attention because of their promising applications in optoelectronic devices.However,previous studies are mainly limited to molecular-based compounds that usually exhibit narrow bandgaps.Here,we report all-inorganic Li_(9)Na_(3)Rb_(2)(SO_(4))_(7) as an ultrawide-bandgap NLO switchable material. | Yanqiang Li Congling Yin Xiaoyan Yang Xiaojun Kuang Jie Chen Lunhua He Qingran Ding Sangen Zhao Maochun Hong Junhua Luo | 2021 | CCS Chemistry2021，3，7： | 1 |
| 13 | An ultra-stable microporous supramolecular framework with highly selective adsorption and separation of water over ethanol显示文摘A microporous supramolecular framework with high water and thermal stability can selectively absorb water molecules over methanol or ethanol due to the suitable channels.The model separation test on columns shows that an ultra-pure ethanol(99.9%)can be obtained from the mixture of ethanol/water(95:5).Additionally,after refluxing the desolvated sample in 95%ethanol at 60℃for 5 h,the purity of ethanol rises up to 97.43%,which is obviously higher than 96.56%for 4 A molecular sieves. | Zhengyi Di Jiandong Pang Falu Hu Mingyan Wu Maochun Hong | 2021 | Nano Research2021，14，8： | 1 |
| 14 | Nonpolar Na_(10)Cd(NO_(3))_(4)(SO_(3)S)_(4) Exhibits a Large Second-Harmonic Generation显示文摘Conventional wisdom says that nonpolar structures do not favorably produce strong second-harmonic generation(SHG)responses since the polarization in their microscopic functional groups are counteracted.Herein,we report the first nonlinear optical thiosulfate,Na_(10)Cd(NO_(3))_(4)(SO_(3)S)_(4),which crystallizes in a nonpolar space group of P−4.However,this thiosulfate exhibits a strong SHG response of about 4.2 times that of the benchmark KH2PO4,which is larger than those of polar sulfates.According to first-principles calculations and a flexible dipole model,the SHG enhancement is mainly ascribed to the larger flexibility of the S=S bond in the SO_(3)S tetrahedra in comparison with the S–O bond in the SO4 tetrahedra.These findings indicate that constructing flexible bonds is an effective strategy to design highperformance nonlinear optical materials regardless of polarity. | Youchao Liu Youquan Liu Zheshuai Lin Yanqiang Li Qingran Ding Xin Chen Lina Li Sangen Zhao Maochun Hong Junhua Luo | 2022 | CCS Chemistry2022，4，2： | 1 |

| 18 | Organic polystyrene and inorganic silica double shell protected lead halide perovskite nanocrystals with high emission efficiency and superior stability显示文摘The practical application of all-inorganic semiconductor lead halide perovskite nanocrystals(LHP NCs)has been limited by their poor stability.Recently,a lot of research on core-shell structure has been done to improve the stability of perovskite NCs,but the effect was far from the application requirements.Herein,we,for the first time,report a convenient approach to synthesize organic-inorganic double shell CsPbBr_(3)@SiO_(2)@polystyrene(PS)NCs with an inter-core of CsPbBr_(3),the intermediate layer of SiO_(2)shell,and outmost PS shell.Particularly,the CsPbBr_(3)@SiO_(2)@PS NCs maintained more than 90%of their initial photoluminescence(PL)intensity under one month's ultraviolet lamp irradiation or in 85℃ and 85%relative humidity(RH)condition.The white-light-emitting-diodes(WLEDs)were fabricated by encapsulating commercial InGaN chip with CsPbBr_(3)@SiO_(2)@PS NCs and K2SiF6:Mn^(4+)(KSF:Mn^(4+))phosphor with a luminous efficacy of~100 lm/W at 20 mA current and a color gamut of 128%of the National Television Standards Committee(NTSC)standard.In addition,these WLEDs still maintain 91%of the initial luminous efficacy after 1200 h of continuous lighting.These results demonstrated that double shell-protected CsPbBr_(3)perovskite NCs have great potential in the field of WLEDs. | Shujian Wang Dejian Chen Kunyuan Xu Jie Hu Decai Huang Maochun Hong Haomiao Zhu | 2023 | Nano Research2023，16，7： | 1 |
