| 1 | Tianwen-1 MINPA observations in the solar wind显示文摘The Mars Ion and Neutral Particle Analyzer(MINPA)is one of the three scientific instruments onboard the Tianwen-1 orbiter to investigate the Martian space environment.During Tianwen-1’s transfer orbit to Mars,the MINPA was switched on to measure the solar wind ions.Here,we present the first results of the MINPA observations in the solar wind.During cruise,nearly half of the MINPA ion field-of-view(FOV)was blocked by the lander capsule;thus only the solar-wind ions with azimuthal speeds pointing towards the unblocked FOV sectors could be detected.We perform a detailed comparison of the MINPA’s solar wind observations with data from Earth-based missions when MINPA reached its count-rate peak,finding a general consistency of the ion moments between them.The blocking effect due to the lander is evaluated quantitatively under varying solar-wind velocity conditions.Despite the blocking effect,the MINPA’s solar wind measurements during the transfer orbit suggest a good performance. | AiBing Zhang LingGao Kong WenYa Li Lei Li BinBin Tang ZhaoJin Rong Yong Wei JiJie Ma YiTeng Zhang LiangHai Xie YuXian Wang JianSen He Bin Liu WenJing Wang Bin Su JiaWei Li Xu Tan Fang Wang TaiFeng Jin FuHao Qiao Peter Wurz Yan Zhu YunFei Bai YiRen Li XinBo Zhu YueQiang Sun YongLiao Zou Chi Wang | 2022 | Earth and Planetary Physics2022，6，1： | 5 |
| 2 | Stability and bifurcation control of a neuron system under a novel fractional-order PD controller显示文摘In this paper, we address the problem of bifurcation control for a delayed neuron system. By introducing a new fractional-order Proportional-Derivative(PD) feedback controller, this paper aims to control the stability and Hopf bifurcation through adjusting the control gain parameters. The order chosen in PD controller is different with that of the integer-order neuron system. Sufficient conditions for guaranteeing the stability and generating Hopf bifurcation are constructed for the controlled neuron system. Finally,numerical simulation results are illustrated to verify our theoretical derivations and the relationships between the onset of the Hopf bifurcation and the gain parameters are obtained. | SHI Shuo XIAO Min RONG LiNa ZHENG WeiXing TAO BinBin CHENG ZunShui XU FengYu | 2019 | Science China(Technological Sciences)2019，62，12： | 3 |
| 3 | The solar wind plasma upstream of Mars observed by Tianwen-1:Comparison with Mars Express and MAVEN显示文摘On the great journey to Mars,China’s first planetary exploration mission,the Tianwen-1 came within 26 million kilometers of Mars from 31 October 2020 to 25 January 2021 and was getting closer to its destination,the red planet,in search of answers to the cataclysmic climate change that occurred in Martian history.Both the escape of the Martian atmosphere and the loss of surface water were firmly influenced by solar activities.Tianwen-1 provided a unique chance to depict the solar wind streams between Earth and Mars during the minimum of Solar Cycle 25.During the three-month cruise phase of Tianwen-1,the solar wind flows were successively observed at Earth,Tianwen-1,and Mars.After the field of view correction and noise reduction,the solar wind velocity and density measured by Tianwen-1 show good agreement with those at Earth and Mars.The results indicate that the performance of the ion analyzer onboard the Tianwen-1 orbiter is reliable and stable.It is worth looking forward to the joint observations of ion escape with other Mars probes in the following Martian years. | Kai FAN Limei YAN Yong WEI Aibing ZHANG Linggao KONG Markus FRÄNZ Fei HE Lihui CHAI Chongjing YUAN Yuqi WANG Jun ZHONG Zhaojin RONG Zhonghua YAO Yongxin PAN Jun CUI Jiansen HE Wenya LI Binbin TANG Chi WANG | 2022 | Science China Earth Sciences2022，65，4： | 2 |

| 7 | Mechanical properties,components and decay resistance of Populus davidiana bioincised by Coriolus versicolor显示文摘The experiment was conducted to improve the decay resistance of wood by increasing the wood preservatives uptake and penetration depth by bioincising with Coriolus versicolor.The mechanical properties of bioincised Populus davidiana sapwood were measured.The changes of wood components(lignin,cellulose and hemicellulose)were analyzed by FTIR.The staining treatment using potassium permanganate was to measure the preservatives uptake and penetration depth in wood specimens.The decay resistance of bioincised specimens impregnated with IPBC and CA was assessed against C.versicolor and Gloeophyllum trabeum using bioincised P.davidiana sapwood and untreated controls.The results showed that the mechanical properties of the bioincised specimens were changed with the incubation time and mass loss.The mechanical strength was decreased after 17 days compared to that of the specimens bioincised<13 days.The bioincised specimens demonstrated the deeper penetration depth than the un-bioincised specimens.It was significant correlation(P<0.01)between penetration depth and incubation time.The average value of the penetration depth of the bioincised specimens was deeper than the control groups by 158.7%.By FTIR analysis,the biodegradation ability of C.versicolor to decay cellulose and hemicellulose was weaker than that of lignin.The bioincising treatment significantly increased the wood uptake of IPBC and CA,and reached the maximum uptake value at 17 and 13 days,respectively.Summarily,the bioincising pretreatment can obviously improve the wood decay resistance against C.versicolor and G.trabeum following by introducing the IPBC and CA. | Lulu Chang Binbin Rong Guoqi Xu Qingkai Meng Lihai Wang | 2020 | Journal of Forestry Research2020，31，5： | 0 |
| 8 | Ferromagnetism of Ni-Doped ZnO Powders Prepared by Sol-Gel Method above Room Temperature显示文摘The magnetic and structural properties of 2% Ni-doped ZnO powers prepared by sol-gel method were studied. X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM) of the sample do not show existence of any signal of second phase. The X-photoelectron spectroscopy (XPS) of the sample shows the chemical valence of Ni is +2 and the real Ni concentration is 2.19% determined by X-ray fluorescence spectra (XRFS). The magnetic property performed with superconducting quantum interference device (SQUID) shows that the sample exhibits ferromagnetism above room temperature and the Curie temperature (TC) is about 600 K. | Li Binbin Zhang Rong Xiu Xiangqian Tao Zhikuo Chen Lin Xie Zili Zheng Youdou Yu Huiqiang | 2006 | Journal of Rare Earths2006，24，z1： | 0 |

| 11 | 3D-printed,bi-layer,biomimetic artificial periosteum for boosting bone regeneration显示文摘Periosteum,a membrane covering the surface of the bone,plays an essential role in maintaining the function of bone tissue—and especially in providing nourishment and vascularization during the bone regeneration process.Currently,most artificial periostea have relatively weak mechanical strength and a rapid degradation rate,and they lack integrated angiogenesis and osteogenesis functions.In this study,a bi-layer,biomimetic,artificial periosteum composed of a methacrylated gelatin–nano-hydroxyapatite(GelMA-nHA)cambium layer and a poly(N-acryloyl 2-lycine)(PACG)-GelMA-Mg^(2+)fibrous layer was fabricated via 3D printing.The GelMA-nHA layer is shown to undertake the function of improving osteogenic differentiation of rat bone marrow mesenchymal stem cells with the sustainable release of Ca^(2+) from nHA nanoparticles.The hydrogen-bonding-strengthened P(ACG-GelMA-L)-Mg^(2+)hydrogel layer serves to protect the inner defect site and prolong degradation time(60 days)to match new bone regeneration.Furthermore,the released magnesium ion exhibits a prominent effect in regulating the polarization phenotype of macrophage cells into theM2 phenotype and thus promotes the angiogenesis of the human umbilical vein endothelial cells in vitro.This bi-layer artificial periosteum was implanted into a critical-sized cranial bone defect in rats,and the 12-week post-operative outcomes demonstrate optimal new bone regeneration. | Yage Sun Ziwei Gao Xiaoping Zhang Ziyang Xu Yahan Zhang Binbin He Rong Yang Qian Zhang Qiang Yang Wenguang Liu | 2022 | Bio-Design and Manufacturing2022，5，3： | 0 |
