| 1 | Characteristics and Origin of Tight Oil Accumulations in the Upper Triassic Yanchang Formation of the Ordos Basin,North-Central China显示文摘The Upper Triassic oil accumulations in the Ordos Basin is the most successful tight oil play in China,with average porosity values of less than 10% and permeability values below 1.0 mD.This study investigated the geological characteristics and origin of the tight oil accumulations in the Chang 6 member of the Upper Triassic Yanchang Formation in the Shanbei area based on over 50,000 petrological,source-rock analysis,well logging and production data.The tight oil accumulation of the Chang 6 member is distributed continuously in the basin slope and the centre of the basin.The oilwater relationships are complex.Laumontite dissolution pores are the most important storage spaces,constituting 30%-60% of total porosity and showing a strong positive relationship with oil production.The pore-throat diameter is less than 1 μm,and the calculated critical height of the oil column is much larger than the tight sand thickness,suggesting that the buoyancy was probably of limited importance for oil migration.The pressure difference between the source rocks and sandstone reservoirs is inferred to have provided driving force for hydrocarbon migration.Two factors of source-reservoir configuration and laumontite dissolution contributed to the formation of the Chang 6 tight oil accumulations.Intense hydrocarbon generation and continuous sand bodies close to the hydrocarbon kitchen are the foundation for the large-scale oil distribution.Dissolution of feldspar-laumontite during the process of organic matter evolution generated abundant secondary pores and improved the reservoir quality. | WU Songtao ZOU Caineng ZHU Rukai YAO Jingli TAO Shizhen YANG Zhi ZHAI Xiufen CUI Jingwei LIN Senhu | 2016 | Acta Geologica Sinica(English Edition)2016，90，5： | 13 |
| 2 | CRA-40/Atmosphere—The First-Generation Chinese Atmospheric Reanalysis(1979–2018):System Description and Performance Evaluation显示文摘Atmospheric reanalysis reproduces the past atmospheric conditions through assimilation of historical meteorological observations with fixed version of a numerical weather prediction(NWP)model and data assimilation(DA)system.It is widely used in weather,climate,and even business-related research and applications.This paper reports the development of CMA’s first-generation global atmospheric reanalysis(RA)covering 1979–2018(CRA-40;CRA refers to CMA-RA).CRA-40 is produced by using the Global Spectral Model(GSM)/Gridpoint Statistical Interpolation(GSI)at a 6-h time interval and a TL574 spectral(34-km)resolution with the model top at 0.27 hPa.A large number of reprocessed satellite data and widely collected conventional observations were assimilated during the reanalyzing process,including the reprocessed atmospheric motion vector(AMV)products from FY-2C/D/E/G satellites,dense conventional observations(at about 120 radiosonde and 2400 synoptic stations)over China,as well as MWHS-2 and GNSS-RO observations from FY-3C.The reanalysis fitting to observations is improved over time,especially for surface pressure with root-mean-square error reduced from 1.05 hPa in 1979 to 0.8 hPa,and for upper air temperature from 1.65 K in 1979 to 1.35 K,in 2018.The patterns of global analysis increments for temperature,specific humidity,and zonal wind are consistent with the changes in the observing system.Near surface temperature from the model’s 6-h forecast reflects the global warming trend reasonably.The CRA-40 precipitation pattern matches well with those of GPCP and other reanalyses.CRA-40 also successfully captures the QBO and its vertical and temporal development,hemispherical atmospheric circulation change,and moisture transport by the East Asian summer monsoon.CRA is now operationally running in near real time as a climate data assimilation system in CMA. | Zhiquan LIU Lipeng JIANG Chunxiang SHI Tao ZHANG Zijiang ZHOU Jie LIAO Shuang YAO Jingwei LIU Minyan WANG Huiying WANG Xiao LIANG Zhisen ZHANG Yan YAO Ting ZHU Zhe CHEN Wenhui XU Lijuan CAO Hui JIANG Kaixi HU | 2023 | Journal of Meteorological Research2023，37，1： | 4 |
| 3 | Experimental Investigation on Micro Deep Drawing of Stainless Steel Foils with Different Microstructural Characteristics显示文摘In the present work,austenitic stainless steel(ASS)304 foils with a thickness of 50μm were first annealed at temperatures ranging from 700 to 1100℃for 1 h to obtain different microstructural characteristics.Then the effects of microstructural characteristics on the formability of ASS 304 foils and the quality of drawn cups using micro deep drawing(MDD)were studied,and the mechanism involved was discussed.The results show that the as-received ASS 304 foil has a poor formability and cannot be used to form a cup using MDD.Serious wrinkling problem occurs on the drawn cup,and the height profile distribution on the mouth and the symmetry of the drawn cup is quite non-uniform when the annealing temperature is 700℃.At annealing temperatures of 900 and 950℃,the drawn cups are both characterized with very few wrinkles,and the distribution of height profile,symmetry and mouth thickness are uniform on the mouths of the drawn cups.The wrinkling becomes increasingly significant with a further increase of annealing temperature from 950 to 1100℃.The optimal annealing temperatures obtained in this study are 900 and 950℃for reducing the generation of wrinkling,and therefore improving the quality of drawn cups.With non-optimized microstructure,the distribution of the compressive stress in the circumferential direction of the drawn foils becomes inhomogeneous,which is thought to be the cause of the occurrence of localized deformation till wrinkling during MDD. | Jingwei Zhao Tao Wang Fanghui Jia Zhou Li Cunlong Zhou Qingxue Huang Zhengyi Jiang | 2021 | Chinese Journal of Mechanical Engineering2021，34，2： | 2 |
| 4 | MDP25 mediates the fine-tuning of microtubule organization in response to salt stress显示文摘Microtubules are dynamic cytoskeleton structures playing fundamental roles in plant responses to salt stress.The precise mechanisms by which microtubule organization is regulated under salt stress are largely unknown.Here,we report that Arabidopsis thaliana MICROTUBULE-DESTABILIZING PROTEIN 25(MDP25;also known as PLASMA MEMBRANEASSOCIATED CATION-BINDING PROTEIN 1(PCaP1))helps regulate microtubule organization.Under salt treatment,elevated cytosolic Ca^(2+) concentration caused MDP25 to partially dissociate from the plasma membrane,promoting microtubule depolymerization.When Ca^(2+) signaling was blocked by BAPTA-AM or LaCl_(3),microtubule depolymerization in wild-type and MDP25-overexpressing cells was slower,while there was no obvious change in mdp25 cells.Knockout of MDP25 improved microtubule reassembly and was conducive to microtubule integrity under long-term salt treatment and microtubule recovery after salt stress.Moreover,mdp25 seedlings exhibited a higher survival rate under salt stress.The presence microtubule-disrupting reagent oryzalin or microtubule-stabilizing reagent paclitaxel differentially affected the survival rates of different genotypes under salt stress.MDP25 promoted microtubule instability by affecting the catastrophe and rescue frequencies,shrinkage rate and time in pause phase at the microtubule plus-end and the depolymerization rate at the microtubule minus-end.These findings reveal a role for MDP25 in regulating microtubule organization under salt treatment by affecting microtubule dynamics. | Peizhi Yang Jingwei Jin Jingru Zhang Dan Wang Xuechun Bai Wenfei Xie Tianming Hu Xuan Zhao Tonglin Mao Tao Qin | 2022 | Journal of Integrative Plant Biology2022，64，6： | 1 |
| 5 | Isolation and identification of a novel coronavirus from wild bird显示文摘A novel coronavirus strain was isolated from laryngotracheal swab of wild partridge and designated as partridge/GD/S14/2003 (S14). Its whole genomic sequence was obtained (GenBank Accession number: AY646283) through RT-PCR amplification, cloning, nucleotide sequencing, and analysis by the DNASTAR program. To investigate the origin of the virus, we further analyzed the nucleotide sequences of the main structural proteins, and compared those with other available virus isolates. Our results showed that the highest nucleotide homologies between the S1 gene of S14 strain and those of nephrogenic-type strains JX1-99 and TJ2-96 were 94.6% and 93.4%, respectively. In addition, a relatively high genetic identity, 85% and 84.3%, respectively, was detected between S1 gene of S14 and those of strains QXIBV and LX4. The results suggested that the S14 strain may be originated from or related to nephrogenic-type and proventriculus-type infectious bronchitis virus (IBV). The highest nucleotide homology between the S2 gene of S14 strain and those of QXIBV and LX4 was 85% and 84.3%, respectively and all of them belonged to group II coronaviruses. The highest nucleotide homology between the M gene of S14 strain and those of strains SAIB20 and GD6-98 was 90.6% and 90.2%, respectively by which S14 belonged to group III. Although they displayed high level of genetic identity in S1 and S2 gene, there was lower homology of M coding sequences between S14 and BJ, and between S14 and QXIBV strains. Phylogenetic analysis of N gene indicated that group I strains might evolve from RNA recombination between strain H52 and Gray; while group II strains from strain H120 and D1466. S14 strain had the highest N gene homology with strain QXIBV which was 95.7%, thus classified as a group III member. Strains SAIB20 and GD6-98 which were closely related to the M gene of S14 strain belonged to group I and IV, respectively. A possible role of partridge S14 strain may play in the process of coronavirus evolution is discussed. | ZHANG Guihong FU Jiadong REN Tao CAO Weisheng LUO Kaijiang XU Chenggang XIN Chaoan JIANG Jingwei LIAO Ming | 2006 | Progress in Natural Science:Materials International2006，16，12： | 1 |

| 7 | A HAase/NIR responsive surface on titanium implants for treating bacterial infection and improving osseointegration显示文摘Bacterial infection and insufficient osseointegration are critical factors affecting the long-term success of titanium-based implants.Unfortunately,the direct application of antibiotic on Ti implants easily leads to poor cytocompatibility,as well as the production of drug-resistant bacteria.So,in this work,we designed a prospective antibacterial strategy by combining photothermal and ciprofloxacin(CIP).The synergistic effect of photothermal and antibiotic may provide an effective bacteriostatic efficacy without sacrificing osteogenesis at a mild condition of moderate temperature and less antibiotic.Herein,CIP was loaded into mesoporous polydopamine(MPDA)nanoparticles(MPDA@CIP),which were anchored on the surface of titanium and finally covered with sodium hyaluronate-catechol(HAc)coating.The hydrophilic HAc layer could inhibit the early adhesion of bacteria,and some bacteria could secrete bacterial hyaluronidase to accelerate the degradation of HAc.This enabled smart enzyme-triggered release of antimicrobials at the site of infection on-demand and avoided unwanted side effects on normal tissues.In addition,NIR light irradiation had a positive influence on both CIP release and MPDA nanoparticle’s photothermal effect.Moreover,before anchoring MPDA@CIP,by the construction of hydroxyapatite microstructure on Ti sur-face with micro-arc oxidation and alkali heat treatment,the ability of bone formation of Ti could be promoted also.Both in vitro as well as in vivo assays demonstrated that functional Ti has an excellent antibacterial effect and osteogenic ability. | Dan Li Danyang Wang Ye He Bailong Tao Xiaoxia Liu Yulu Yang Lu Tan Yuchen Zhang Jingwei Hu Weihu Yang Yu Tang Kaiyong Cai | 2023 | Journal of Materials Science & Technology2023，，12： | 0 |
| 8 | High carrier mobility and strong fluorescence emission: Toward highly sensitive single-crystal organic phototransistors显示文摘Organic single crystals(OSCs)offer a unique combination of both individual and collective properties of the employed molecules,but it remains highly challenging to achieve OSCs with both high mobilities and strong fluorescence emissions for their potential applications in multifunctional optoelectronics.Herein,we demonstrate the design and synthesis of two novel triphenylamine-functionalized thienoacenes-based organic semiconductors,4,8-distriphenylamineethynylbenzo[1,2-b:4,5-b′]dithiophene(4,8-DTEBDT)and 2,6-distriphenylamineethynylbenzo[1,2-b:4,5-b′]dithiophene(2,6-DTEBDT),with high-mobility and strong fluorescence emission.The two compounds show the maximum mobilities up to 0.25 and 0.06 cm^(2) V^(-1) s^(-1),the photoluminescence quantum yields(PLQYs)of 51% and 45%,and the small binding energies down to 55.13 and 58.79 meV.The excellent electrical and optical properties ensured the application of 4,8-DTEBDT and 2,6-DTEBDT single crystals in ultrasensitive UV phototransistors,achieving high photoresponsivity of 9.60×105 and 6.43×10^(4) AW^(-1),and detectivity exceeding 5.68×10^(17) and 2.99×10^(16) Jones. | Jingwei Tao Zhaoyang Liu Dan Liu Huanli Dong Jiangbo Jing Jiaxing Song Leijing Liu Bin Xu Wenjing Tian | 2023 | Aggregate2023，4，2： | 0 |
| 9 | Surface modification of titanium substrate via combining photothermal therapy and quorum-sensing-inhibition strategy for improving osseointegration and treating biofilm-associated bacterial infection显示文摘Insufficient osseointegration and biofilm-associated bacterial infection are important challenges for clinical application of titanium(Ti)-based implants.Here,we constructed mesoporous polydopamine(MPDA)nanoparticles(NPs)loaded with luteolin(LUT,a quorum sensing inhibitor),which were further coated with the shell of calcium phosphate(CaP)to construct MPDA-LUT@CaP nanosystem.Then,MPDA-LUT@CaP NPs were immobilized on the surface of Ti implants.Under acidic environment of bacterial biofilm-infection,the CaP shell of MPDA-LUT@CaP NPs was rapidly degraded and released LUT,Ca^(2+)and PO_(4)^(3-)from the surface of Ti implant.LUT could effectively inhibit and disperse biofilm.Furthermore,under near-infrared irradiation(NIR),the thermotherapy induced by the photothermal conversion effect of MPDA destroyed the integrity of the bacterial membrane,and synergistically led to protein leakage and a decrease in ATP levels.Combined with photothermal therapy(PTT)and quorum-sensing-inhibition strategy,the surface-functionalized Ti substrate had an antibacterial rate of over 95.59%against Staphylococcus aureus and the elimination rate of the formed biofilm was as high as 90.3%,so as to achieve low temperature and efficient treatment of bacterial biofilm infection.More importantly,the modified Ti implant accelerated the growth of cell and the healing process of bone tissue due to the released Ca^(2+)and PO_(4)^(3-).In summary,this work combined PTT with quorum-sensing-inhibition strategy provides a new idea for surface functionalization of implant for achieving effective antibacterial and osseointegration capabilities. | Jingwei Hu Yao Ding Bailong Tao Zhang Yuan Yulu Yang Kun Xu Xuan Li Peng liu Kaiyong Cai | 2022 | Bioactive Materials2022，7，12： | 0 |
| 10 | Insight into structure evolution of carbon nitrides and its energy conversion as luminescence显示文摘A series of carbon nitride(CN)materials represented by graphitic carbon nitride(g-C3N4)have been widely used in bioimaging,biosensing,and other fields in recent years due to their nontoxicity,low cost,and high luminescent quantum efficiency.What is more attractive is that the luminescent properties such as wavelength and intensity can be regulated by controlling the structure at the molecular level.Hence,it is time to summarize the related research on CN structural evolution and make a prospect on future developments.In this review,we first summarize the research history and multiple structural evolution of CN.Then,the progress of improving the luminescence performance of CN through structural evolution was discussed.Significantly,the relationship between CN structure evolution and energy conversion in the forms of photoluminescence,chemiluminescence,and electrochemiluminescence was reviewed.Finally,key challenges and opportunities such as nanoscale dispersion strategy,luminous efficiency improving methods,standardization evaluation,and macroscopic preparation of CN are highlighted. | Hao Zhang Jingwei Zhang Wenjie Chen Minjia Tao Xianguang Meng Yuanjian Zhang Guifu Zuo | 2024 | Carbon Energy2024，6，2： | 0 |
| 11 | Digitally programmable organic light‐emitting tetrodes显示文摘Limited to the structure of traditional light‐emitting devices,electronic devices that can directly convert machine language into human visual information without introducing any back‐end circuit are still not easy to achieve.Based on a specially designed three‐phase co‐planar electrode structure,a new type of three‐phase alternating current driven organic light‐emitting device with the integration of emission and control functions,full‐color tunability and simple device structure is demonstrated in this study.We integrate the light‐emitting function of color‐tunable light‐emitting devices and the switching of three triodes in a single three phase organic light‐emitting device.The state control of luminous color and luminance intensity merely requires the introduction of a kind of machine language,that is an easy‐to‐program 6‐bit binary number coded digital signals.The color adjustable area covers 66%of the color triangle of the National Television System Committee.Such simple and easy‐to‐integrate light‐emitting system has great potential applications in the next‐generation man‐machine interface. | Junpeng Ji Biao Yang Chaohong Zhang Yulu Cai Jingwei Chen Changbin Zhao Tao Wang Lijie Wu Ming Liu Junwu Bai Jiangfeng Wang Zhongbin Wu Shufen Chen Haifeng Ling Zhongfu An Yonghua Chen Jianpu Wang Wei Huang Hong Meng | 2023 | SmartMat2023，4，2： | 0 |
