1Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management.Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng 2015Chinese Birds2015,,3:20
2Green fluorescent protein (GFP) transgenic pig produced by somatic cell nuclear transfer显示文摘Transgenic somatic cell nuclear transfer is a very promising route for producing transgenic farm ani-mals. Research on GFP transgenic pigs can provide useful information for breeding transgenic pigs, human disease models and human organ xenotransplantation. In this study, a liposomal transfection system was screened and transgenic embryos were reconstructed by nuclear transfer of GFP positive cells into enucleated in vitro matured oocytes. The development of reconstructed embryos both in vitro and in vivo was observed, and GFP expression was determined. The results showed that porcine fe-tal-derived fibroblast cells cultured with 4.0 μL/mL liposome and 1.6 μg/mL plasmid DNA for 6 h re-sulted in the highest transfection rate (3.6%). The percentage of GFP reconstructed embryos that de-veloped in vitro to the blastocyst stage was 10%. Of those the GFP positive percentage was 48%. Re-constructed transgenic embryos were transferred to 10 recipients. 5 of them were pregnant, and 3 de-livered 6 cloned piglets in which 4 piglets were transgenic for the GFP as verified by both GFP protein expression and GFP DNA sequence analysis. The percentage of reconstructed embryos that resulted in cloned piglets was 1.0%; while the percentage of piglets that were transgenic was 0.7%. This is the first group of transgenic cloned pigs born in China, marking a great progress in Chinese transgenic cloned pig research.LIU ZhongHua SONG Jun WANG ZhenKun TIAN JiangTian KONG QingRan ZHENG Zhong YIN Zhi GAO Li MA HaiKun SUN Shuang LI YuTian WANG HongBin R S PRATHER 2008Chinese Science Bulletin2008,53,7:8
3HIGHER ORDER SPECTRAL ANALYSIS IN FAULT DIAGNOSIS OF ROTORS显示文摘The nonlinear properties of rotating machinery vibration signals are presented. The relationship between faults and quadratic phase coupling is discussed. The mechanism that gives rise to quadratic phase coupling is analyzed, and the coupling models are summarized. As a result, higher order spectra analysis is introduced into fault diagnosis of rotors. A brief review of the properties of higher order spectra is presented. Furthermore, the bicoherence spectrum is employed to extract the features that signify the machinery condition. Experiments show that bicoherence spectrum patterns of different faults are quite different, so it is proposed to identify the faults in rotors.Yang Jiangtian Xu Jinwu School of Mechanical Engineering, Beijing University of Sicence and Technology 2001Chinese Journal of Mechanical Engineering2001,14,1:4
4A CRISPR/Cas12a-empowered surface plasmon resonance platform for rapid and specific diagnosis of the Omicron variant of SARS-CoV-2显示文摘The outbreak of the COVID-19 pandemic was partially due to the challenge of identifying asymptomatic and presymptomatic carriers of the virus,and thus highlights a strong motivation for diagnostics with high sensitivity that can be rapidly deployed.On the other hand,several concerning SARS-CoV-2 variants,including Omicron,are required to be identified as soon as the samples are identified as‘positive’.Unfortunately,a traditional PCR test does not allow their specific identification.Herein,for the first time,we have developed MOPCS(Methodologies of Photonic CRISPR Sensing),which combines an optical sensing technology-surface plasmon resonance(SPR)with the‘gene scissors’clustered regularly interspaced short palindromic repeat(CRISPR)technique to achieve both high sensitivity and specificity when it comes to measurement of viral variants.MOPCS is a low-cost,CRISPR/Cas12a-systemempowered SPR gene-detecting platform that can analyze viral RNA,without the need for amplification,within 38 min from sample input to results output,and achieve a limit of detection of 15 fM.MOPCS achieves a highly sensitive analysis of SARS-CoV-2,and mutations appear in variants B.1.617.2(Delta),B.1.1.529(Omicron)and BA.1(a subtype of Omicron).This platform was also used to analyze some recently collected patient samples from a local outbreak in China,identified by the Centers for Disease Control and Prevention.This innovative CRISPR-empowered SPR platform will further contribute to the fast,sensitive and accurate detection of target nucleic acid sequences with single-base mutations.Zhi Chen Jingfeng Li Tianzhong Li Taojian Fan Changle Meng Chaozhou Li Jianlong Kang Luxiao Chai Yabin Hao Yuxuan Tang Omar AAl-Hartomy Swelm Wageh Abdullah GAl-Sehemi Zhiguang Luo Jiangtian Yu Yonghong Shao Defa Li Shuai Feng William J.Liu Yaqing He Xiaopeng Ma Zhongjian Xie Han Zhang 2022National Science Review2022,9,8:3
5CRISPR-Cas12a-Empowered Electrochemical Biosensor for Rapid and Ultrasensitive Detection of SARS-CoV-2 Delta Variant显示文摘Coronavirus disease 2019(COVID-19)is a highly contagious disease caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).The gold standard method for the diagnosis of SARS-CoV-2 depends on quantitative reverse transcription-polymerase chain reaction till now,which is time-consuming and requires expensive instrumentation,and the confirmation of variants relies on further sequencing techniques.Herein,we first proposed a robust technique-methodology of electrochemical CRISPR sensing with the advantages of rapid,highly sensitivity and specificity for the detection of SARS-CoV-2 variant.To enhance the sensing capability,gold electrodes are uniformly decorated with electro-deposited gold nanoparticles.Using DNA template identical to SARS-CoV-2 Delta spike gene sequence as model,our biosensor exhibits excellent analytical detection limit(50 fM)and high linearity(R2=0.987)over six orders of magnitude dynamic range from 100 fM to 10 nM without any nucleic-acid-amplification assays.The detection can be completed within 1 h with high stability and specificity which benefits from the CRISPR-Cas system.Furthermore,based on the wireless micro-electrochemical platform,the proposed biosensor reveals promising application ability in point-of-care testing.Chenshuo Wu Zhi Chen Chaozhou Li Yabin Hao Yuxuan Tang Yuxuan Yuan Luxiao Chai Taojian Fan Jiangtian Yu Xiaopeng Ma Omar AAl-Hartomy SWageh Abdullah GAl-Sehemi Zhiguang Luo Yaqing He Jingfeng Li Zhongjian Xie Han Zhang 2022Nano-Micro Letters2022,14,10:2
6Oxygen Evolution Reaction in Energy Conversion and Storage: Design Strategies Under and Beyond the Energy Scaling Relationship显示文摘The oxygen evolution reaction(OER)is the essential module in energy conversion and storage devices such as electrolyzer,rechargeable metal–air batteries and regenerative fuel cells.The adsorption energy scaling relations between the reaction intermediates,however,impose a large intrinsic overpotential and sluggish reaction kinetics on OER catalysts.Developing advanced electrocatalysts with high activity and stability based on non-noble metal materials is still a grand challenge.Central to the rational design of novel and high-efficiency catalysts is the development and understanding of quantitative structure–activity relationships,which correlate the catalytic activities with structural and electronic descriptors.This paper comprehensively reviews the benchmark descriptors for OER electrolysis,aiming to give an in-depth understanding on the origins of the electrocatalytic activity of the OER and further contribute to building the theory of electrocatalysis.Meanwhile,the cutting-edge research frontiers for proposing new OER paradigms and crucial strategies to circumvent the scaling relationship are also summarized.Challenges,opportunities and perspectives are discussed,intending to shed some light on the rational design concepts and advance the development of more efficient catalysts for enhancing OER performance.Jiangtian Li 2022Nano-Micro Letters2022,14,7:2

12Effect of Longitudinal Plastic Bending of Pipeline on Buckle Propagation Pressure显示文摘A plastic ring-beam model simulating the longitudinal transition zone of submarine pipelines in the buckle propagation is presented. The nonlinear relationships between the buckle propagation pressure and the length of the transition zone and the position parameter of the longitudinal plastic hinge are derived using the energy principle. The related values are obtained by means of solving a set of nonlinear equations. The model conforms better to reality than the ring models for considering the effect of the longitudinal plastic bending of the transition zone. The computations for some stainless steel and aluminium tubes with different geometrical parameters are performed. The results obtained agree better with the experimental results than existing theoretical predictions.Zhu, Dashan Huang, Yuying Cheng, Jiangtian 1991China Ocean Engineering1991,6,1:0
13Electrostatic beneficiation of fly ash in a free-falling system显示文摘A systematic study of fly ash electrostatic beneficiation in a free-falling separation system was carried out to provide fundamental understanding of the separation efficiency for the design of a suitable process for industrial applications. The parameters investigated included feeding position, electric field strength, particle size and moisture content. Particles larger than 105 m presented the best separation efficiency among four different size fractions, whereas particles smaller than 44 m showed minimal separation. However, sonication treatments helped separation by liberating more carbon from ash particles, although particle sizes were reduced as well. Experiments also showed that exposure to moisture significantly altered charging behavior of fly ash and its subsequent separation due to more free mobile ion-induced charge exchanges. The optimal feeding position was found to be slightly on the side of the negative electrode, leading to a 30% reduction in loss-on-ignition (LOI) and a 45% recovery in a single pass. A simplified mechanical model based on trajectory analysis for charged particles in an electrical field was in reasonable agreement with experimental results.Lifeng Zhang Jiangtian Hou Xiaotao T.Bi John R.Grace Travis Janke Claudio Arato 2012Particuology2012,10,2:0
14Thermal comfort in a building with Trombe wall integrated with phase change materials in hot summer and cold winter region without air conditioning显示文摘Trombe wall and phase change materials(PCMs)are two effective ways to regulate indoor thermal comfort.However,Trombe wall surfers from overheating in summer and PCMs suffer from low heat transfer rate caused by the limited thermal conductivity.To compensate the shortcomings of the two methods,this paper proposed a Trombe wall system integrated with PCMs.Based on a light-weight building envelope in Changsha,China,the thermal comfort of 10 kinds of Trombe wall systems with PCMs with a melting temperature of 18-28℃ were studied.Taking the integrated indoor discomfort duration(I_(D)),integrated indoor discomfort degree-hour(I_(DH)),indoor air temperature(T_(in)),PCM liquid fraction(γ)and heat flux across wall(q)as evaluation indexes,the indoor thermal comfort was assessed in hot summer and cold winter region.Results show that the Trombe wall helped PCMs complete the phase change process effectively.Trombe wall with PCM25 next to the wall inner surface possessed the lowest annual I_(D) and I_(DH),as 2877 h and 12,974℃·h,respectively.Compared with the values in a traditional building,the I_(D) and I_(DH) were reduced by 7.01% and 14.14%.In order to give full play to the heat storage and heat release of the Trombe wall with PCMs,PCMs with phase change temperature 7℃ lower than the peak ambient temperature in summer or 8℃ higher than the winter night temperature was recommended according to regional climate conditions.Jie Li Yuan Zhang Ziyang Zhu Jiangtian Zhu Jing Luo Fen Peng Xiaoqin Sun 2024Energy and Built Environment2024,5,1:0
