| 1 | DEVELOPMENT OF EXPERIMENTAL METHODS FOR IMPACT TESTING BY COMBINING HOPKINSON PRESSURE BAR WITH OTHER TECHNIQUES显示文摘The split Hopkinson pressure bar(SHPB) technique and the wave propagation inverse analysis(WPIA) technique are both extensively used to experimentally investigate the impact behavior of materials, although neither of them alone provides a fully satisfactory analysis. In the present paper, attention is given to new experimental techniques by incorporating a damagemodified constitutive model into the SHPB technique and combining the Hopkinson pressure bar(HPB) technique with WPIA. First, to distinguish the response due to dynamic constitutive behavior and the response due to dynamic damage evolution, the SHPB method incorporating a damage-modified constitutive model is developed, including an explicit damage-modified Zhu–Wang–Tang model and an implicit damage-modified constitutive model. Second, when the SHPB results become invalid, a method of combining new Lagrange inverse analyses with the HPB technique is developed, including cases of the HPB arranged in front of a long specimen and behind the specimen. As examples of these new methods, typical results are given for nonlinear viscoelastic polymers and concretes considering damage evolution, a super-elastic Ti–Ni alloy with phase transformation and an aluminum foam with shock waves propagating within it. | Lili Wang Shisheng Hu Liming Yang Zijian Sun Jue Zhu Huawei Lai Yuanyuan Ding | 2014 | Acta Mechanica Solida Sinica2014，27，4： | 9 |
| 2 | Study on the Technology of Ni-P Electroless Plating on the Mg Alloy显示文摘Base on the analysis for the corrosion mechanism of the Mg alloys,the technology of Ni-P directly electroless plating on the Mg-10Li-1Zn alloys was studied.The effects of the pre-treatment on the morphologies of substrate and plating films were investigated,The result shows that Ni-P electroless plating could be divided two steps:the induction period and the rapid deposition period.The Ni-P film is amorphous structure:A excellent Ni-P coating can be obtained under the optimal parameter.The Ni-P coating can obviously improve the corrosion resistance of Mg alloy in variety environment. | Liu Yihan Sun Huawei Jiang Yanan | 2012 | 稀有金属材料与工程2012，41，S1： | 5 |
| 3 | 食品废物两相高温半干法厌氧发酵生产沼气初步研究显示文摘为了提高两相厌氧发酵工艺的生产性能,该文研究了一种新的两相半干法厌氧发酵沼气生产系统,即在水解相中批式发酵,每次从工作容积为4L的产烷相中取500mL接种液,与食品废物混合后发酵1~2d,再全部输入产烷相继续生产沼气,如此循环。实验运行温度为50℃,食品废物总固体TS和挥发性固体VS分别为19.3%和16.1%,产烷相先在4gVS·d-1的进料率下单相运行至稳定,稳定期日产气量为(4.09±0.03)L(甲烷占69.0%),pH为7.50±0.02,TS和VS分别为(1.05±0.02)%和(0.64±0.02)%。稳定的产烷相与水解相联合后,水解相在60~700g的进料量下都能正常产气,但氢气含量较低。产烷相在进料量600g时产气量最高,为29.1L/d,随后受到抑制,受抑制前的甲烷含量为72.4%~74.0%,TS和VS含量也在该进料量后达到最高峰,分别为3.50%和2.32%。研究结果表明新的两相半干法厌氧发酵沼气生产系统有效提高了生产性能,在今后的研究中,需要降低从产烷相输入水解相的接种液量,以更好抑制水解相产烷微生物,提高产氢性能,还可使产烷相更加稳定,承受更高的进料量。 | 泮进明 张瑜 Zhang Ruihong 朱保宁 Sun Huawei 应义斌 | 2008 | 农业工程学报2008，24，7： | 4 |
| 4 | Dual-channel type tunable field-effect transistors based on vertical bilayer WS2(1−x)Se2x/SnS2 heterostructures显示文摘Layered semiconductor heterostructures are essential elements in modern electronic and optoelectronic devices.Dynamically engineering the composition of these heterostructures may enable the flexible design of the properties of heterostructure-based electronics and optoelectronics as well as their optimization.Here,we report for the first time a two-step chemical vapor deposition approach for a series of WS2(1−x)Se2x/SnS2 vertical heterostructures with high-quality and large areas.The steady-state photoluminescence results exhibit an obvious composition-related quenching ratio,revealing a strong coherence between the band offset and the charge transfer efficiency at the junction interface.Based on the achieved heterostructures,dual-channel backgate field-effect transistors were successfully designed and exhibited typical composition-dependent transport behaviors,and pure n-type unipolar transistors to ambipolar transistors were realized in such systems.The direct vapor growth of these novel vertical WS2(1−x)Se2x/SnS2 heterostructures could offer an interesting system for probing new physical properties and provide a series of layered heterostructures for high-quality devices. | Biyuan Zheng Dong Li Chenguang Zhu Jianyue Lan Xingxia Sun Weihao Zheng Huawei Liu Xuehong Zhang Xiaoli Zhu Yexin Feng Tao Xu Litao Sun Gengzhao Xu Xiao Wang Chao Ma Anlian Pan | 2020 | InfoMat2020，2，4： | 3 |
| 5 | QTL mapping of drought tolerance traits in soybean with SLAF sequencing显示文摘Drought stress is an important factor affecting soybean yield.Improving drought tolerance of soybean varieties can increase yield and yield stability when the stress occurs.Identifying QTL related to drought tolerance using molecular marker-assisted selection is able to facilitate the development of drought-tolerant soybean varieties.In this study,we used a high-yielding and drought-sensitive cultivar‘Zhonghuang 35’and a drought-tolerant cultivar‘Jindou 21’to establish F6:9 recombinant inbred lines.We constructed a highdensity genetic map using specific locus amplified fragment sequencing(SLAF-Seq)technology.The genetic map contained 8078 SLAF markers distributing across 20 soybean chromosomes with a total genetic distance of 3780.98 c M and an average genetic distance of0.59 c M between adjacent markers.Two treatments(irrigation and drought)were used in the field tests,the Additive-Inclusive Composite Interval Mapping(ICIM-ADD)was used to call QTL,and plant height and seed weight per plant were used as the indicators of drought tolerance.We identified a total of 23 QTL related to drought tolerance.Among them,seven QTL(q PH2,q PH6,q PH7,q PH17,q PH19-1,q PH19-2,and q PH19-3)on chromosomes 2,6,7,17,and 19 were related to plant height,and five QTL(q SWPP2,q SWPP6,q SWPP13,q SWPP17,and q SWPP19)on chromosomes 2,6,13,17,and 19 were related to seed weight and could be considered as the major QTL.In addition,three common QTL(q PH6/q SWPP6,q PH17/q SWPP17,and q PH19-3/q SWPP19)for both plant height and seed weight per plant were located in the same genomic regions on the same chromosomes.Three(q PH2,q PH17,and q PH19-2)and four novel QTL(q SWPP2,q SWPP13,q SWPP17,and q SWPP19)were identified for plant height and seed weight per plant,respectively.Two pairs of QTL(q PH2/q SWPP2 and q PH17/q SWPP17)were also common for both plant height and seed weight per plant.These QTL and closely linked SLAF markers could be used to accelerate breeding for drought tolerant cultivars via MAS. | Honglei Ren Jianan Han Xingrong Wang Bo Zhang Lili Yu Huawei Gao Huilong Hong Rujian Sun Yu Tian Xusheng Qi Zhangxiong Liu Xiaoxia Wu Li-Juan Qiu | 2020 | The Crop Journal2020，8，6： | 2 |
| 6 | Geochronology, geochemistry and Hf isotopes of andesites in the Sandaowanzi gold deposit(Great Xing’an Range, NE China): implications for petrogenesis, tectonic setting,and mineralization显示文摘The Sandaowanzi gold deposit is an extremely Au-rich deposit in the Northern Great Hinggan Range in recent years.Zircon U-Pb geochronology,Hf isotope analysis,and the geochemistry of andesites of the Longjiang Formation from the Sandaowanzi gold deposit were used to investigate the origin,magmatic evolution as well as mineralization and tectonic setting of the Early Cretaceous epithermal gold deposits in the northern Great Hinggan Range area.Zircon U-Pb dating reveals an emplacement age of 123.4±0.3 Ma,indicating that the andesites of the Sandaowanzi gold deposit was formed during the Early Cretaceous.The andesites are enriched in light rare earth elements relative to heavy rare earth elements and have weak negative Eu anomalies(δEu=0.76-0.90).The rocks are also enriched in large-ion lithophile elements,such as Rb,Ba,Th,U,and K,and depleted in the high-field-strength elements,such as Nb,Ta,and P.These characteristics are typical of volcanic rocks related to subduction.Igneous zircons from the andesite samples have relatively homogeneous Hf isotope ratios,176Hf/177Hf values of 0.282343-0.282502,εHf(t)values of-12.58 to-6.95,and two-stage model ages(TDM2)of 1743-1431 Ma.The characteristics of the andesites of the Longjiang Formation are consistent with derivation from partial melting of enriched mantle wedge metasomatized by subducted-slab-derived fluids.These rocks formed in an extensional environment associated with the closure of the Mongol-Okhotsk Ocean and subduction of the Paleo-Pacific Plate.Mineralization occurred towards the end of volcanism,and the magmatic activity and mineralization are products of the same geodynamic setting. | Runtao Yu Bile Li Fengyue Sun Zhihua Li Huawei Li Yufan Shi | 2021 | Acta Geochimica2021，40，2： | 2 |

| 13 | Inactivated Pseudomonas PE(△Ⅲ)exotoxin fused to neutralizing epitopes of PEDV S proteins produces a specific immune response in mice显示文摘Porcine epidemic diarrhea(PED)caused by the porcine epidemic diarrhea virus(PEDV),is a severe infectious and devastating swine disease that leads to serious economic losses in the swine industry worldwide.An increased number of PED cases caused by variant PEDV have been reported in many countries since 2010.S protein is the main immunogenic protein containing some B-cell epitopes that can induce neutralizing antibodies of PEDV.In this study,the construction,expression and purification of Pseudomonas aeruginosa exotoxin A(PE)without domain Ⅲ(PE△Ⅲ)as a vector was performed for the delivery of PEDV S-A or S-B.PE(△Ⅲ)PEDV S-A and PE(△Ⅲ)PEDV S-B recombinant proteins were confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blot analysis.The immunogenicity of PEDV S-A and PEDV S-B subunit vaccines were evaluated in mice.The results showed that PEDV-S-B vaccine could not only induce specific humoral and Th1 type-dominant cellular immune responses,but also stimulate PEDV-specific mucosal immune responses in mice.PEDV-S-B subunit vaccine is a novel candidate mucosal vaccine against PEDV infection. | Leqiang Sun Yajie Tang Keji Yan Huanchun Chen Huawei Zhang | 2021 | Animal Diseases2021，1，3： | 1 |

| 15 | Short-term offshore extension of Brahmaputra-Ganges and Irrawaddy freshwater plumes to the central northern Bay of Bengal based on in situ and satellite observations显示文摘In this study, the short-term offshore extension of Brahmaputra-Ganges(BG) and Irrawaddy freshwater plumes to the central northern Bay of Bengal(BoB) was investigated based on in situ and satellite observations. In the summer and winter of 2015, two significant freshening events with periods of weeks were observed from a moored buoy at 15°N, 90°E in the BoB. Soil Moisture Active Passive(SMAP) satellite sea surface salinity compares well with the in situ data and shows that these freshening events are directly related to the short-term offshore extension of the BG and Irrawaddy freshwater, respectively. These data combined with the altimeter sea level anomaly data show that the offshore extending plumes result from freshwater modulated by eddies. During summer, the BG freshwater is modulated by a combination of three closely located eddies: a large anticyclonic eddy(ACE) off the northwestern BoB coast and two cyclonic eddies in the northern BoB. Consequently, the freshwater extends offshore from the river mouth and forms a long and narrow tongue-shaped plume extending southwestward to the central BoB. During winter, the Irrawaddy freshwater is modulated by two continuous ACEs evolved from Rossby wave propagating westward from the Irrawaddy Delta off Myanmar, forming a tongueshaped plume extending to the central BoB. Strong salinity fronts are formed along the boundaries of these tongue-shaped plumes. These findings confirm good capability of the SMAP data to investigate the short-term offshore extension of the BG and Irrawaddy freshwater. This study provides direct evidences of the pathways of the offshore extension of the BG and Irrawaddy freshwater and highlights the role of eddies in the northern BoB freshwater plume variability. | Zhiyuan Li Saihua Huang Xiaohua Zhu Zhilin Sun Yu Long Huawei Xie | 2021 | Acta Oceanologica Sinica2021，40，5： | 0 |

| 17 | Reconfigurable Vortex-like Paramagnetic Nanoparticle Swarm with Upstream Motility and High Body-length Ratio Velocity显示文摘Drug delivery systems with high-targeted doses can minimize excipients,reduce side effects,and improve efficacy.Human blood circulation is a complex circulatory system,and the motion control of microrobots in the static flow field in vitro is completely different from in vivo.How to achieve precise counterflow motion for targeted drug delivery without vascular blockage and immune rejection is the biggest challenge for micro-nano robots.Here,we propose a control method that enables vortex-like paramagnetic nanoparticle swarm(VPNS)to move upstream against the flow.By mimicking the clustering motion of wild herring schools and the rolling of leukocytes,VPNS are incredibly stable even when subjected to high-intensity jet impacts in the blood environment,can travel upstream,anchor at the target location,and dissipate when the magnetic field is withdrawn,which greatly reduces the risk of thrombosis.VPNS can also upstream along the vessel wall without an additional energy source and has a marked targeted therapeutic effect on subcutaneous tumors. | Luyao Wang Han Gao Hongyan Sun Yiming Ji Li Song Lina Jia Chutian Wang Chan Li Deyuan Zhang Ye Xu Huawei Chen Lin Feng | 2023 | Research2023，，4： | 0 |
| 18 | Epitaxial van der Waals contacts for low schottky barrier MoS_(2) field effect transistors显示文摘Small contact resistance and low Schottky barrier height(SBH)are the keys to energy-efficient electronics and optoelectronics.Two-dimensional(2D)semiconductors-based field effect transistors(FETs),holding great promise for next-generation information circuits,still suffer from poor contact quality at the metal–semiconductor junction interface,which severely hinders their further applications.Here,a novel contact strategy is proposed,where Bi_(2)Te_(3)nanosheets with high conductivity were in-situ epitaxially grown on MoS_(2)as van der Waals contacts,which can effectively avoid the damage to MoS_(2)caused during the device manufacturing process,leading to a high-performance MoS_(2)FET.Moreover,the small work function difference between Bi_(2)Te_(3)and MoS_(2)(Bi_(2)Te_(3):4.31 eV,MoS_(2):4.37 eV,measured by Kelvin probe force microscopy(KPFM)),enables small band bending and Ohmic contact at the junction interface.Electrical characterizations indicate that the MoS_(2)FET device with Bi_(2)Te_(3)contacts possesses a high current on/off ratio(5×107),large effective carrier mobility(90 cm^(2)/(V·s)),and low flat-band SBH(60 meV),which is favorable as compared with MoS_(2)FET with traditional Cr/Au electrodes contacts,and superior to the vast majority of the reported chemical vapor deposition(CVD)MoS_(2)-based FET device.The demonstration of epitaxial van der Waals Bi_(2)Te_(3)contacts will facilitate the application of 2D MoS_(2)nanosheet in next-generation low-power consumption electronics and optoelectronics. | Huawei Liu Lizhen Fang Xiaoli Zhu Chenguang Zhu Xingxia Sun Gengzhao Xu Biyuan Zheng Ying Liu Ziyu Luo Hui Wang Chengdong Yao Dong Li Anlian Pan | 2023 | Nano Research2023，16，9： | 0 |
| 19 | Genome-wide association study of seedling nitrogen-use efficiency-associated traits in common wheat(Triticum aestivum L.)显示文摘Nitrogen(N)fertilizer application is essential for crop-plant growth and development.Identifying genetic loci associated with N-use efficiency(NUE)could increase wheat yields and reduce environmental pollution caused by overfertilization.We subjected a panel of 389 wheat accessions to N and chlorate(a nitrate analog)treatments to identify quantitative trait loci(QTL)controlling NUE-associated traits at the wheat seedling stage.Genotyping the panel with a 660K single-nucleotide polymorphism(SNP)array,we identified 397 SNPs associated with N-sensitivity index and chlorate inhibition rate.These SNPs were merged into 49 QTL,of which eight were multi-environment stable QTL and 27 were located near previously reported QTL.A set of 135 candidate genes near the 49 QTL included TaBOX(F-box family protein)and TaERF(ethylene-responsive transcription factor).A Tabox mutant was more sensitive to low-N stress than the wild-type plant.We developed two functional markers for Hap 1,the favorable allele of TaBOX. | Huawei Shi Weichong Wang Lifeng Gao Jirong Wu Chengmei Hu Huishu Yan Yugang Shi Ning Li Youzhi Ma Yongbin Zhou Zhaoshi Xu Jun Chen Wensi Tang Kai Chen Daizhen Sun Yuxiang Wu Ming Chen | 2024 | The Crop Journal2024，12，1： | 0 |
| 20 | Integration of chemical and biological methods:A case study of polycyclic aromatic hydrocarbons pollution monitoring in Shandong Peninsula,China显示文摘Polycyclic aromatic hydrocarbons(PAHs),as persistent toxic substances(PTS),have been widely monitored in coastal environment,including seawater and sediment.However,scientific monitoring methods,like ecological risk assessment and integrated biomarker response,still need massive researches to verify their availabilities.This study was performed in March,May,August and October of 2018 at eight sites,Yellow River estuary(S1),Guangli Port(S2),Xiaying(S3),Laizhou(S4),Inner Bay(S5),Outer Bay(S6),Hongdao(S7)and Hongshiya(S8)of Shandong Peninsula,China.The contents of 16 priority PAHs in local seawater and sediment were determined,by which ecological risk assessment risk quotient(RQ)for seawater and sediment quality guidelines(SQGs)were calculated to characterize the PAHs pollution.Meanwhile,multiple biomarkers in the digestive gland of clam Ruditapes philippinarum were measured to represent different biological endpoints,including ethoxyresorufin-O-deethylase(EROD),glutathione S-transferase(GST),sulfotransferase(SULT),superoxide dismutase(SOD)and lipid peroxidation(LPO),by which integrated biomarker response(IBR)was calculated to provide a comprehensive assessment of environmental quality.Taken together,these results revealed the heaviest pollution at S2 as both PAHs concentrations and biomarkers responses reflected,and supported the integrated biomarker response as a useful tool for marine environmental monitoring,through its integration with SQGs. | Zeyuan Li Yunhao Cao Huawei Qin Yuanqing Ma Luqing Pan Jiawei Sun | 2022 | Journal of Environmental Sciences2022，34，1： | 0 |
