| 1 | Recursive algorithm and accurate computation of dyadic Green's functions for stratified uniaxial anisotropic media显示文摘A recursive algorithm is adopted for the computation of dyadic Green's functions in three-dimensional stratified uniaxial anisotropic media with arbitrary number of layers. Three linear equation groups for computing the coefficients of the Som- merfeld integrals are obtained according to the continuity condition of electric and magnetic fields across the interface between different layers, which are in corre- spondence with the TM wave produced by a vertical unit electric dipole and the TE or TM wave produced by a horizontal unit electric dipole, respectively. All the linear equation groups can be solved via the recursive algorithm. The dyadic Green's functions with source point and field point being in any layer can be conveniently obtained by merely changing the position of the elements within the source term of the linear equation groups. The problem of singularities occurring in the Sommer- feld integrals is efficiently solved by deforming the integration path in the complex plane. The expression of the dyadic Green's functions provided by this paper is terse in form and is easy to be programmed, and it does not overflow. Theoretical analysis and numerical examples show the accuracy and effectivity of the algo-rithm. | WEI BaoJun ZHANG GengJi LIU QingHuo | 2008 | Science in China(Series F)2008，51，1： | 19 |

| 3 | Single-cell biomagnifier for optical nanoscopes and nanotweezers显示文摘Optical microscopes and optical tweezers,which were invented to image and manipulate microscale objects,have revolutionized cellular and molecular biology.However,the optical resolution is hampered by the diffraction limit;thus,optical microscopes and optical tweezers cannot be directly used to image and manipulate nano-objects.The emerging plasmonic/photonic nanoscopes and nanotweezers can achieve nanometer resolution,but the high-index material structures will easily cause mechanical and photothermal damage to biospecimens.Here,we demonstrate subdiffraction-limit imaging and manipulation of nano-objects by a noninvasive device that was constructed by trapping a cell on a fiber tip.The trapped cell,acting as a biomagnifier,could magnify nanostructures with a resolution of 100 nm(λ/5.5)under white-light microscopy.The focus of the biomagnifier formed a nano-optical trap that allowed precise manipulation of an individual nanoparticle with a radius of 50 nm.This biomagnifier provides a high-precision tool for optical imaging,sensing,and assembly of bionanomaterials. | Yuchao Li Xiaoshuai Liu Baojun Li | 2019 | Light(Science & Applications)2019，8，1： | 9 |
| 4 | Interface electron collaborative migration of Co–Co3O4/carbon dots:Boosting the hydrolytic dehydrogenation of ammonia borane显示文摘Ammonia borane(AB)is an excellent candidate for the chemical storage of hydrogen.However,its practical utilization for hydrogen production is hindered by the need for expensive noble-metal-based catalysts.Herein,we report Co-Co3O4 nanoparticles(NPs)facilely deposited on carbon dots(CDs)as a highly efficient,robust,and noble-metal-free catalyst for the hydrolysis of AB.The incorporation of the multiinterfaces between Co,Co3O4 NPs,and CDs endows this hybrid material with excellent catalytic activity(rB=6816 mLH2 min^-1 gCo^-1)exceeding that of previous non-noble-metal NP systems and even that of some noble-metal NP systems.A further mechanistic study suggests that these interfacial interactions can affect the electronic structures of interfacial atoms and provide abundant adsorption sites for AB and water molecules,resulting in a low energy barrier for the activation of reactive molecules and thus substantial improvement of the catalytic rate. | Han Wu Min Wu Boyang Wang Xue Yong Yushan Liu Baojun Li Baozhong Liu Siyu Lu | 2020 | Journal of Energy Chemistry2020，29，9： | 7 |
| 5 | 2-Gy whole-body irradiation significantly alters the balance of CD4^(+)CD25^(-) T effector cells and CD4^(+)CD25^(+)Foxp3^(+) T regulatory cells in mice显示文摘CD4^(+)CD25^(+) T regulatory(Treg)cells are critical in inducing and maintaining immunological self-tolerance as well as transplant tolerance.The effect of low doses of whole-body irradiation(WBI)on CD41CD251Foxp31 Treg cells has not been determined.The proportion,phenotypes and function of CD4^(+)CD25^(+) Treg cells were investigated 0.5,5 and 15 days after euthymic,thymectomized or allogeneic bone marrow transplanted C57BL/6 mice received 2-Gy c-rays of WBI.The 2-Gy WBI significantly enhanced the ratios of CD41CD251 Treg cells and CD4^(+)CD25^(+)Foxp3^(+) Treg cells to CD41 T cells in peripheral blood,lymph nodes,spleens and thymi of mice.The CD41CD251 Treg cells of the WBI-treated mice showed immunosuppressive activities on the immune response of CD4^(+)CD25^(+) T effector cells to alloantigens or mitogens as efficiently as the control mice.Furthermore,2-Gy c-ray WBI significantly increased the percentage of CD4^(+)CD25^(+)Foxp3^(+) Treg cells in the periphery of either thymectomized mice or allogeneic bone marrow transplanted mice.The in vitro assay showed that ionizing irradiation induced less cell death in CD4^(+)CD25^(+)Foxp3^(+) Treg cells than in CD4^(+)CD25^(+) T cells.Thus,a low dose of WBI could significantly enhance the level of functional CD41CD251Foxp31 Treg cells in the periphery of naive or immunized mice.The enhanced proportion of CD41CD251Foxp31 Treg cells in the periphery by a low dose of WBI may make hosts more susceptible to immune tolerance induction. | Yanyan Qu Baojun Zhang Shuchun Liu Aijun Zhang Tingting Wu Yong Zhao | 2010 | Cellular & Molecular Immunology2010，7，6： | 7 |
| 6 | Mesoscale simulation of discontinuous dynamic recrystallization using the cellular automaton method显示文摘A dynamic recrystallization (DRX) cellular automaton (CA) model that can mark the microstructure with DRX circle was developed. The effects of initial grain size on the stress-strain curve, mean grain size and DRX fraction were mainly investigated, and the simulated results were compared with those obtained from previous researches. The results show that the shape of the stress-strain curve is sensitive, while the stress and mean grain size at the steady state are insensitive to the initial grain size. The transition from a multiple-peak stress-strain curve to a single-peak one can be explained by variations in DRX circle fraction, and the initial grain size to make this transition is between 70 and 80 μm. | Baojun YU Xiaojun GUAN Lijun WANG Qingkai ZENG Qianqian LIU Yu CAO | 2011 | Acta Metallurgica Sinica(English Letters)2011，24，4： | 6 |
| 7 | Maffucci syndrome with unilateral limb: a case report and review of the literature显示文摘Maffucci syndrome is a congenital, non-hereditary mesodermal dysplasia manifested by multiple enchondromas and hemangiomas. It is associated with diverse secondary musculoskeletal deformities, which is exceedingly rare. We report a case of hemangiomas and enchondromas localized in the unilateral limb in a patient with Maffucci syndrome. Treatment consists of orthopedic and surgical intervention to minimize deformities and for cosmetic purpose. Careful surveillance for malignant degeneration of both skeletal and non-skeletal tumors, especially in the brain and abdomen, is essential. | Hua Gao Baojun Wang Xi Zhang Fengqi Liu Ying Lu | 2013 | Chinese Journal of Cancer Research2013，25，2： | 6 |
| 8 | Deficiency of Mouse CD4^+CD25^+Foxp3^+ Regulatory T Cells in Xenogeneic Pig Thymus-Grafted Nude Mice Suffering from Autoimmune Diseases显示文摘Xenogeneic thymus transplantation can efficiently induce specific immune tolerance to donor antigens in athymic recipients. However, many nude mice suffer from autoimmune diseases (AID) for over 10 weeks after xenogeneic thymus transplantation. CD4+CD25+Foxp3+ regulatory T (Treg) cells were recently determined to play a pivotal role in keeping immune tolerance in humans and mice. Thus, we investigated this subpopulation of Treg cells in the periphery of pig thymus-grafted nude mice suffering from AID. Our results showed that the expression of Foxp3, CTLA-4 and GITR on mouse CD4+CD25+ T cells and the ratio of CD4+CD25+Foxp3+ Treg cells to CD4+ T cells were significantly decreased in the periphery of pig thymus-grafted nude mice suffering from AID, compared with healthy pig or mouse thymus-grafted nude mice. Furthermore, mouse CD4+CD25+ T cells in pig thymus-grafted nude mice suffering from AID showed more severe deficiency in immunosuppressive function compared with the counterpart in xenogeneic pig or syngeneic thymus-grafted nude mice without AID. Thus, the decreased frequency, altered phenotype and functional deficiency of mouse CD4+CD25+ Treg cells in pig thymus-grafted nude mice may contribute to the development of AID in this model. | Baojun Zhang Chenming Sun Yanyan Qu Aijun Zhang Jun Liu Lianjun Zhang Zeqing Niu Yong Zhao | 2008 | Cellular & Molecular Immunology2008，5，5： | 6 |
| 9 | Analysis of the ore-controlling structure of the Shihu gold deposit, Hebei Province and deep-seated ore-prospecting prediction显示文摘Under the guidance of the theory of mantle-branch structure-associated metallogenesis and on the basis of the geological characteristics, analysis of the ore-forming and ore-controlling structures, the geochemical characteristics of metallogenesis, the source of ore-forming materials, changes in the physical and chemical conditions of metallogenesis, changes in the vertical width of ore veins, and changes in gold grade of the Shihu gold deposit, the mechanism of its metallogenesis was discussed and the rules of vertical variation of ore veins were summarized in this study. It is pointed out that the orebodies under exploitation at present time should be in the middle and upper portions of gold veins in the Shihu gold mining district. Particularly on the basis of the characteristics of mantle-branch structure-associated metallogenesis, it is indicated that metallogenesis is controlled mainly by such ore-forming conditions as temperature and pressure. Deep-seated ore-forming fluids are characterized mainly by injection and precipitation. So the vein bodies in the adjacent metallogenic structures are of obvious comparability, and there would be great prospects for ore search both at depth and in the periphery of the Shihu gold deposit. Therefore, ore prospecting should be strengthened both at depth and in the peripheries. | NIU Shuyin WANG Baode SUN Aiqun CHEN Chao WANG Zili MA Baojun WANG Wenxue JIANG Xiaoping ZHAO Yongli GAO Yincang LIU Huabin QIU Jianping | 2009 | Chinese Journal Of Geochemistry2009，28，4： | 6 |
| 10 | Co-Co304@carbon core-shells derived from metal-organic framework nanocrystals as efficient hydrogenevolution catalysts显示文摘Controllable pyrolysis of metal-organic frameworks (MOFs) in confined spacesis a promising strategy for the design and development of advanced functionalmaterials. In this study, Co-C0304@carbon composites were synthesized viapyrolysis of a Co-MOFs@glucose polymer (Co-MOFs@GP) followed by partialoxidation of Co nanoparticles (NPs). The pyrolysis of Co-MOFs@GP generated acore-shell structure composed of carbon shells and Co NPs. The controlled partialoxidation of Co NPs formed Co-Co304 heterojunctions confined in carbon shells.Compared with Co-MOFs@GP and Co@carbon-n (Co@C-n), Co-C0304@carbon-n(Co-Co304@C-n) exhibited higher catalytic activity during NaBH4 hydrolysis.Co-C0304@C-II provided a maximum specific H2 generation rate of5,360 mL.min-l.gco-1 at room temperature due to synergistic interactionsbetween Co and C0304 NPs. The Co NPs also endowed Co-C0304@C-n with theferromagnetism needed to complete the magnetic momentum transfer process. | Yanyan Liu Guosheng Han Xiaoyu Zhang Congcong Xing Chenxia Du Huaqiang Cao Baojun Li | 2017 | Nano Research2017，10，9： | 5 |
| 11 | Optical trapping and orientation of Escherichia coli cells using two tapered fiber probes显示文摘We report on the optical trapping and orientation of Escherichia coli(E.coli) cells using two tapered fiber probes.With a laser beam at 980 nm wavelength launched into probe I, an E. coli chain consisting of three cells was formed at the tip of probe I. After launching a beam at 980 nm into probe II, the E.coli at the end of the chain was trapped and oriented via the optical torques yielded by two probes. The orientation of the E. coli was controlled by adjusting the laser power of probe II. Experimental results were interpreted by theoretical analysis and numericalsimulations. | Jianbin Huang Xiaoshuai Liu Yao Zhang Baojun Li | 2015 | Photonics Research2015，3，6： | 4 |
| 12 | Factors Controlling Hydrocarbon Accumulation in Jurassic Reservoirs in the Southwest Ordos Basin, NW China显示文摘The sedimentary, paleogeomorphological and reservoir characteristics of the Jurassic Yan’an Formation in the southwestern Ordos Basin, northwestern China, were studied by means of casting thin sections, scanning electron microscopy, inclusion analysis and identification of low-amplitude structures. A model for reservoir formation is established, and the controlling effects of sedimentary facies, paleotopography, low-amplitude structures and formation water on oil reservoirs are revealed. There are significant differences in the sedimentary characteristics, structural morphology and paleowater characteristics between the reservoirs above the Yan 10 Member and those in the Yan 9 to Yan 7 Members. The Yan 10 Member contains fluvial sediments, whereas the Yan 9 to Yan 7 members contain delta-plain anastomosing-river deposits. The distribution of high-permeability reservoir is controlled by pre-Jurassic paleogeomorphology and sedimentary facies. Some of these facies exhibit high porosity and high permeability in a lowpermeability background. The main hydrocarbon accumulation period was the late Early Cretaceous, filling was continuous, and the charging strength altered from weak to strong and then from strong to weak. The Yan 10 reservoir is mainly controlled by the paleogeomorphology: hydrocarbons migrated upward at a high speed through the unconformity surface, and accumulated in the favorable traps formed by paleogeomorphic structural units, such as gentle slopes or channel island. Furthermore, groundwater alternation in these areas was relatively stagnant, providing good reservoir preservation conditions. The reservoirs in the Yan 9 and higher members are controlled by the sedimentary facies, lowamplitude structure and paleowater characteristics. Hydrocarbons migrated through the three-dimensional delivery system, influenced by favorable sedimentary facies and high-salinity groundwater, then accumulated in the favorable low-amplitude structural traps that formed during the hydrocarbon production period. | LIU Xin WANG Feng LIU Baojun TIAN Jingchun SHANG Ting MA Jiong ZHANG Zhongyi ZHANG Xiaolei | 2020 | Acta Geologica Sinica(English Edition)2020，94，2： | 4 |
| 13 | Syntenic quantitative trait loci and genomic divergence for Sclerotinia resistance and ?owering time in Brassica napus显示文摘Oilseed rape(Brassica napus) is an allotetraploid with two subgenomes descended from a common ancestor. Accordingly, its genome contains syntenic regions with many duplicate genes, some of which may have retained their original functions, whereas others may have diverged. Here, we mapped quantitative trait loci(QTL) for stem rot resistance(SRR), a disease caused by the fungus Sclerotinia sclerotiorum, and flowering time(FT) in a recombinant inbred line population. The population was genotyped using B.napus 60 K single nucleotide polymorphism arrays and phenotyped in six(FT) and nine(SSR) experimental conditions or environments. In total, we detected 30 SRR QTL and 22 FT QTL and show that some of the major QTL associated with these two traits were co-localized,suggesting a genetic linkage between them. Two SRR QTL on chromosome A2 and two on chromosome C2 were shown to be syntenic, suggesting the functional conservation of these regions. We used the syntenic properties of the genomic regions to exclude genes for selection candidates responsible for QTL-associated traits. For example, 152 of the 185 genes could be excluded from a syntenic A2–C2 region. These findings will help to elucidate polyploid genomics in future studies, in addition to providing useful information for B. napus breeding programs. | Fengqi Zhang Junyan Huang Minqiang Tang Xiaohui Cheng Yueying Liu Chaobo Tong Jingyin Yu Tehrim Sadia Caihua Dong Lingyan Liu Baojun Tang Jianguo Chen Shengyi Liu | 2019 | Journal of Integrative Plant Biology2019，61，1： | 3 |
| 14 | Multiphase microstructure formation and its effect on fracture behavior of medium carbon high silicon high strength steel显示文摘This work investigated the evolution of multiphase microstructure and impact fracture behavior of medium carbon high silicon high strength steel subjected to the austempering treatment at 240,360,and400℃.The results show that martensite,bainite,and retained austenite(RA)are the main microstructural phases.The austempering treatments at 360 and 400℃ caused the formation of carbon-poor ferrite in the matrix,and the transformation of ultrafine bainite into coarse lath bainite and granular bainite,respectively.Thick filmy RA was distributed between bainite laths.The polygonal martensiteaustenite islands and blocky RA formed along the grain boundaries.The average carbon concentration in the matrix decreased with the temperature increase,while the impact toughness initially increased and then dropped with temperature.The quasi-cleavage brittle fracture dominated the impact fracture mechanism of the sample austempered at 240℃ by forming tearing surfaces and tearing steps.The microcracks disappeared in the RA on the prior austenite grain boundaries.On the other side,the fracture surface of the sample austempered at 360℃ exhibited ductile fracture with deep dimples and brittle fracture with cleavage river patterns.The polygonal martensite-austenite islands or blocky RA constrained the microcracks.After austempered at 400℃,the brittle fracture was dominant,showing river patterns,and the microcracks propagated through the granular bainite without any resistance. | Kui Chen Huabing Li Zhouhua Jiang Fubin Liu Congpeng Kang Xiaodong Ma Baojun Zhao | 2021 | Journal of Materials Science & Technology2021，，13： | 3 |
| 15 | A DFT theoretical study of CH_4 dissociation on gold-alloyed Ni(111)surface显示文摘A density-functional theory(DFT)method has been conducted to systematically investigate the adsorption of CHx(x=0~4)as well as the dissociation of CHx(x=1~4)on(111)facets of gold-alloyed Ni surface.The results have been compared with those obtained on pure Ni(111)surface.It shows that the adsorption energies of CHx(x=1~3)are lower,and the reaction barriers of CH4 dissociation are higher in the first and the fourth steps on gold-alloyed Ni(111)compared with those on pure Ni(111).In particular,the rate-determining step for CH4 dissociation is considered as the first step of dehydrogenation on gold-alloyed Ni(111),while it is the fourth step of dehydrogenation on pure Ni(111).Furthermore,the activation barrier in rate-determining step is higher by 0.41 eV on gold-alloyed Ni(111)than that on pure Ni(111).From above results,it can be concluded that carbon is not easy to form on gold-alloyed Ni(111)compared with that on pure Ni(111). | Hongyan Liu Ruixia Yan Riguang Zhang Baojun Wang Kechang Xie | 2011 | Journal of Natural Gas Chemistry2011，20，6： | 2 |
| 16 | Co-CoO_x supported onto TiO_(2) coated with carbon as a catalyst for efficient and stable hydrogen generation from ammonia borane显示文摘Ammonia borane(AB) can be catalytically hydrolyzed to provide hydrogen at room temperature due to its high potentaial for hydrogen storage. Non-precious metal heterogeneous catalysts have broad application in the field of energy catalysis. In this article, catalysts precursor is obtained from Co-Ti-resorcinol-formaldehyde resin by sol–gel method. Co/TiO_(2)@N-C(CTC) catalyst is prepared by calcining the precursor under high temperature conditions in nitrogen atmosphere. Co-CoO_x/TiO_(2)@N-C(COTC) is generated by the controllable oxidation reaction of CTC. The catalyst can effectively promote the release of hydrogen during the hydrolytic dehydrogenation of AB. High hydrogen generation at a specific rate of 5905 m L min^(-1) g_(Co)^(-1) is achieved at room temperature. The catalyst retains its 85% initial catalytic activity even for its fifth time use in AB hydrolysis. The synergistic effect among Co, Co_(3)O_(4) and TiO_(2) promotes the rate limiting step with dissociation and activation of water molecules by reducing its activation energy. The applied method in this study promotes the development of non-precious metals in catalysis for utilization in clean energy sources. | Guang Yang Shuyan Guan Sehrish Mehdi Yanping Fan Baozhong Liu Baojun Li | 2021 | Green Energy & Environment2021，6，2： | 2 |
| 17 | Analysis of the ore-controlling role of Guojiadian mantle branch structure,Northwest Shandong Peninsula,China显示文摘Metallogenesis in the gold ore-concentrated zone of Northwest Shandong Peninsula is closely related to deep processes.The region in the eastern part of North China entered into the stage of mantle plume evolution during the Yanshanian movement,following the long-time stage of stable platform evolution during Paleozoic time.At that time,the ore-concentrated zone of Northwest Shandong Peninsula just entered into the development-evolution stage of the Laiyang sub-mantle plume and the Guojiadian mantle branch structure in its periphery.The core-mantle-source gold was present in the gas-liquid form,and it migrated through mantle plume→sub-mantle plume→mantle branch structure→favorable tectonic expansion zone to the favorable loci of the mantle branch structure,where gold was deposited as ores,thereafter constituting a series of large-to medium-sized gold deposits distributed around the Guojiadian mantle branch structure.This study also dealt with the Jiaojia fault as the main detachment(fault altered rock) belt on the northwestern margin of the mantle branch structure and also presented a basic cognition about the fact that the Sanshandao fault as the listric fault on the hanging wall of the detachment belt.Furthermore,on this basis,this study also pointed out the orientation for further ore prospecting in this region. | NIU Shuyin Sun Aiqun ZHANG Jianzhen MA Baojun WANG Baode CHEN Chao ZHANG Fuxiang LIU Cheng ZHANG Xiaofei | 2012 | Chinese Journal Of Geochemistry2012，31，4： | 2 |
| 18 | Synthesis of AgGa1-xInxSe2 Polycrystalline Materials显示文摘AgGa1-xInxSe2 polycrystals were synthesized by the method of mechanical oscillation and temperature oscillation. X-ray diffraction spectra of polycrystal powder are conformable with the JCPDS cards. Lattice constants a and c calculated from the XRD were found to obey Vegard's law. The melting point of AgGa0.8In0.2Se2 obtained by means of differential scanning calorimetry (DSC) is 796.53 ℃. The DSC curve also show that there are no other transformation points below the melting point. The results indicate that polycrystalline materials synthesized by the method mentioned above are high-quality and can be used to grow single crystals by the vertical Bridgman technology. | Liu Juan Zhao Beijun Zhu Shifu Huang Yi Zhang Jianjun Zhu Weilin Xu Chengfu Chen Baojun Li Ming He Zhiyu | 2006 | Journal of Rare Earths2006，24，z1： | 2 |
| 19 | Clinical and functional comparison of endoprosthetic replacement with intramedullary nailing for treating proximal femur metastasis显示文摘Objective: To evaluate the clinical and functional outcomes of modular endoprosthetic replacement(EPR) compared to proximal femur intramedullary nailing(IMN) for the treatment of proximal femur metastases.Methods: We retrospectively studied the records of patients with proximal femur metastatic lesions treated with surgical stabilization between January 2007 and December 2014 in terms of operation time, blood loss, postoperative score, soreness, Karnofsky performance score(KPS) and survival time.Results: There were 34 patients treated with surgical stabilization. The mean follow-up period was 12.1±8.6 months(range: 10-47 months). Thirteen were treated with EPR and 21 were stabilized with IMN(20 males, 14 females; mean age: 68.7 years). The median survival time was 11.0 months for both groups(P=0.147). The operation time, blood loss and Harris score of IMN group were lower than those of EPR group(P=0.001, P=0.001, P=0.002, respectively).Conclusions: Both EPR and IMN for treating proximal femur metastasis achieved effective clinical outcomes. Therefore, the suitable surgical methods depended on the general conditions and medical requirements of patients, as well as the technical advantages of the doctor. | Hua Gao Zhenyu Liu Baojun Wang Ai Guo | 2016 | Chinese Journal of Cancer Research2016，28，2： | 2 |
