| 1 | Data-driven estimates of global nitrous oxide emissions from croplands显示文摘Croplands are the single largest anthropogenic source of nitrous oxide(N2O) globally, yet their estimates remain difficult to verify when using Tier 1 and 3 methods of the Intergovernmental Panel on Climate Change(IPCC). Here, we re-evaluate global cropland-N2O emissions in 1961–2014, using N-rate-dependent emission factors(EFs) upscaled from 1206 field observations in 180 global distributed sites and high-resolution N inputs disaggregated from sub-national surveys covering 15593 administrative units. Our results confirm IPCC Tier 1 default EFs for upland crops in 1990–2014, but give a ~15% lower EF in 1961–1989 and a ~67% larger EF for paddy rice over the full period. Associated emissions(0.82 ±0.34 Tg N yr–1) are probably one-quarter lower than IPCC Tier 1 global inventories but close to Tier 3 estimates. The use of survey-based gridded N-input data contributes 58% of this emission reduction, the rest being explained by the use of observation-based non-linear EFs. We conclude that upscaling N2O emissions from site-level observations to global croplands provides a new benchmark for constraining IPCC Tier 1 and 3 methods. The detailed spatial distribution of emission data is expected to inform advancement towards more realistic and effective mitigation pathways. | Qihui Wang Feng Zhou Ziyin Shang Philippe Ciais Wilfried Winiwarter Robert B.Jackson Francesco N.Tubiello Greet Janssens-Maenhout Hanqin Tian Xiaoqing Cui Josep G.Canadell Shilong Piao Shu Tao | 2020 | National Science Review2020,7,2: | 7 |
| 2 | Effect of Li+ ion concentration on upconversion emission and temperature sensing behavior of La2O3:Er3+ phosphors显示文摘The effects of Li^+ co-doping concentration on the structure, upconversion luminescence and temperature sensing behavior of Er^(3+):La_2O_3 phosphors were investigated. X-ray diffraction and scanning electron microscopy observations reveal that Li^+ ion co-doping can change the lattice parameter of La_2O_3 host and increase the particle size of the samples. The optical investigation shows that co-doping of Li^+ ions can enhance the upconversion emission of Er^(3+) ions in La_2O_3 matrix effectively. Most importantly, the temperature sensing sensitivity of the samples is found to be dependent on Li^+ co-doping concentration,when the emission intensity ratio of the(~2H_(11/2)→~4 I_(15/2)) and(~4 S_(3/2)→~4 I_(15/2)) transitions of Er^(3+) is chosen as the thermometric index. Both of the optimum upconversion luminescence and temperature sensing sensitivity are obtained for 7 mol% Li^+ co-doped sample. When the Li^+ concentration is beyond 7 mol%,both the quenching in upconversion intensity and the degradation of temperature sensitivity are observed, which may be due to the serious distortion in local crystal field around Er^(3+) ions caused by the excess Li^+ ions. | Guangrun Chen Ruoshan Lei Shiqing Xu Huanping Wang Shilong Zhao Feifei Huang Yin Tian | 2018 | Journal of Rare Earths2018,36,2: | 4 |
| 3 | Pt-Co single atom alloy catalysts: Accelerated water dissociation and hydrogen evolution by strain regulation显示文摘The alkaline hydrogen evolution reaction(HER) on Pt-based catalysts is largely limited by the slow water dissociation kinetics. Pt-based single atom alloy catalysts(SAAC) with water dissociation sites have been demonstrated as excellent alkaline HER catalysts. However, the regulation of their activity and stability at the atomic scale is still a great challenge. Herein, the kinetic and stability issues are successfully resolved via engineering the electronic structure of Pt-Co SAAC by Au-induced tensile strain. The atomic dispersion of Co into the Pt shell was confirmed by extended X-ray absorption fine structure and the electronic structure and catalytic HER performance was modulated by the tensile strain induced by the Pt shell thickness. An inverse volcano-type relation between HER activity and surface strain was found.Density functional theory(DFT) calculations reveal that the Au-induced tensile strain on Pt-Co shell can not only boost the adsorption and dissociation kinetics of water at Co site by upshifting the dband and promoting the electron transfer, but also downshift the d-band center of Pt in Pt-Co shell, leading to optimized H* adsorption/desorption. The champion catalyst provides an overpotential of only 14 m V at the current density of 10 mA cm^(-2). This work not only provides an effective strategy for the construction of single-atom alloy electrocatalysts for high performance toward alkaline HER but also sheds light on the understanding of the reaction mechanism at the atomic level. | Rendian Wan Mi Luo Jingbo Wen Shilong Liu Xiongwu Kang Yong Tian | 2022 | Journal of Energy Chemistry2022,31,6: | 3 |

| 5 | Numerical simulation on directional solidification of Al-Ni-Co alloy based on FEM显示文摘The ratio,of the temperature gradient at the solidifiationfront to the solidification rate of solid-liquid interface,plays a large part in columnar grain growth.The transient temperature fields of directional solidification of Al-Ni-Co alloy were studied by employing a finite element method.The temperature gradient at the solidification front and the solidification rate were analyzed for molten steels pouring at different temperatures.The results show that with different initial pouring temperatures,the individual ratio of the temperature gradient at solidification front to the solidification rate soars up in the initial stage of solidification,then varies within 2,000-6,000℃.s.cm-2,and finally goes down rapidly and even tend to be closed to each other when the solidification thickness reaches 5-6 cm.The simulation result is consistent with the practical production which can provide an available reference for process optimization of directional solidified Al-Ni-Co alloy. | Yang Zhili Chen Dengming Tian Shilong, Liao Daohan Yang Yu | 2010 | China Foundry2010,7,1: | 1 |

| 8 | Utility of Triti-Map for bulk-segregated mapping of causal genes and regulatory elements in Triticeae显示文摘Triticeae species,including wheat,barley,and rye,are critical for global food security.Mapping agronomically important genes is crucial for elucidating molecular mechanisms and improving crops.However,Triticeae includes many wild relatives with desirable agronomic traits,and frequent introgressions occurred during Triticeae evolution and domestication.Thus,Triticeae genomes are generally large and complex,making the localization of genes or functional elements that control agronomic traits challenging.Here,we developed Triti-Map,which contains a suite of user-friendly computational packages specifically designed and optimized to overcome the obstacles of gene mapping in Triticeae,as well as a web interface integrating multi-omics data from Triticeae for the efficient mining of genes or functional elements that control particular traits.The Triti-Map pipeline accepts bothDNA and RNAbulk-segregated sequencing data as well as traditional QTL data as inputs for locating genes and elucidating their functions.We illustrate the usage of Triti-Map with a combination of bulk-segregated ChIP-seq data to detect a wheat disease-resistance gene with its promoter sequence that is absent from the reference genome and clarify its evolutionary process.We hope that Triti-Map will facilitate gene isolation and accelerate Triticeae breeding. | Fei Zhao Shilong Tian Qiuhong Wu Zijuan Li Luhuan Ye Yili Zhuang Meiyue Wang Yilin Xie Shenghao Zou Wan Teng Yiping Tong Dingzhong Tang Ajay Kumar Mahato Moussa Benhamed Zhiyong Liu Yijing Zhang | 2022 | Plant Communications2022,3,4: | 1 |

| 11 | Four decades of full-scale nitrous oxide emission inventory in China显示文摘China is among the top nitrous oxide(N_(2)O)-emitting countries,but existing national inventories do not provide full-scale emissions including both natural and anthropogenic sources.We conducted a four-decade(1980-2020)of comprehensive quantification of Chinese N_(2)0 inventory using empirical emission factor method for anthropogenic sources and two up-to-date process-based models for natural sources.Total N_(2)O emissions peaked at 2287.4(1774.8-2799.9)Gg N_(2)0 yr-1 in 2018,and agriculture-developed regions,like the East,Northeast,and Central,were the top N_(2)O-emitting regions.Agricultural N_(2)O emissions have started to decrease after 2016 due to the decline of nitrogen fertilization applications,while,industrial and energetic sources have been dramatically increasing after 2005.N_(2)O emissions from agriculture,industry,energy,and waste represented 49.3%,26.4%,17.5%,and 6.7% of the anthropogenic emissions in 2020,respectively,which revealed that it is imperative to prioritize N_(2)O emission mitigation in agriculture,industry,and energy.Natural N_(2)O sources,dominated by forests,have been steadily growing from 317.3(290.3-344.1)Gg N_(2)0 yr^(-1) in 1980 to 376.2(335.5-407.2)Gg N_(2)O yr^(-1) in 2020.Our study produces a Full-scale Annual N_(2)O dataset in China(FAN_(2)020),providing emergent counting to refine the current national N,Oinventories. | Minqi Liang Zheyan Zhou Peiyang Ren Han Xiao Xu-Ri Zhongmin Hu Shilong Piao Hanqin Tian Qing Tong Feng Zhou Jing Wei Wenping Yuan | 2024 | National Science Review2024,11,3: | 0 |

| 13 | Structural characterization of thin-walled microbubble cavities显示文摘Whispering gallery mode(WGM)microbubble cavities are a versatile optofluidic sensing platform owing to their hollow core geometry.To increase the light–matter interaction and,thereby,achieve higher sensitivity,thinwalled microbubbles are desirable.However,a lack of knowledge about the precise geometry of hollow microbubbles prevents us from having an accurate theoretical model to describe the WGMs and their response to external stimuli.In this work,we provide a complete characterization of the wall structure of a microbubble and propose a theoretical model for the WGMs in this thin-walled microcavity based on the optical waveguide approach.Structural characterization of the wavelength-scale wall is enabled by focused ion beam milling and scanning electron microscopy imaging.The proposed theoretical model is verified by finite element method simulations.Our approach can readily be extended to other low-dimensional micro-/nanophotonic structures. | MOHAMMED ZIA JALALUDEEN SHILONG LI KE TIAN TOSHIO SASAKI SÍLE NIC CHORMAIC | 2023 | Photonics Research2023,11,8: | 0 |
| 14 | A comparative analysis of reticular crack on ceramic plate driven by thermal shock显示文摘Reticular crack is generally found on the surface of ceramic material that has been subjected to a thermal-shock condition. In the present study, a quantitative effect of thermal shock and quench temperature has been studied and investigated. Experimental tests were carried out to characterize the reticular crack that has been found in the Ge Kiln, which is a famous art of the ancient Chinese culture. After comparative analysis between thermal-shock cracks and the glaze crack patterns of the Ge Kiln porcelain,it is found that this study is expected to provide a powerful tool for recurrence of the long-lost firing and cooling process of the Ge Kiln porcelain. | XiangHong Xu ShiLong Sheng Cheng Tian WenJun Yuan | 2016 | Science China(Physics,Mechanics & Astronomy)2016,59,7: | 0 |
