| 1 | Effect of Cropland Occupation and Supplement on Light-temperature Potential Productivity in China from 2000 to 2008显示文摘There are more people but less land in China,so food safety has always been a most important issue government concerned.With continuous population increase,economic development and environment protection,cropland occupation and supplement are unavoidable.It not only leads to the variation of cropland area,but also makes the light-temperature potential productivity per unit area different due to regional climate differentiation,therefore impacts the total potential productivity and food output eventually.So,it is necessary to analyze the climate differentiation between occupation and supplement cropland areas and to study its impact on total potential productivity,which is significant to reasonably develop natural resources and instruct agricultural arrangement.This study firstly discussed the variation and distribution of occupation and supplement croplands in China from 2000 to 2008,then analyzed the climate differentiation between occupation and supplement cropland areas and its effect on light-temperature potential productivity.The results demonstrate:1) From 2000 to 2008,the cropland variation presented occupation in the south and supplement in the north,but overall decreased.Supplement cropland was mainly from ecological reclamation(77.78%) and was mainly distributed in Northeast China and Northwest China with poor climatic and natural conditions.Occupation cropland was mainly used for construction(52.88%) and ecological restoration(44.78%) purposes,and was mainly distributed in the Huang-Huai-Hai Plain,and the middle and lower reaches of the Changjiang(Yangtze) River with better climatic and natural conditions.2) The climate conditions were quite different in supplement and occupation cropland areas.The annual precipitation,annual accumulated temperature and average annual temperature were lower in the supplement cropland area,and its average po-tential productivity per unit was only 62% of occupation cropland area,which was the main reason for the decrease of total potential productivity.3) Cropland occupation and supplement led to the variation of total potential productivity and its spatial distribution.The productivity decreased in the south and increased in the north,but had a net loss of 4.38315×107 t in the whole country.The increase of cropland area was at the cost of reclaiming natural forest and grassland resources,and destroying natural ecological environment,while the decrease of cropland area was mainly due to a lot of cropland occupied by urban-rural construction,which threatened the sustainable use of cropland resources. | YANG Xiaohuan CHENG Chuanzhou LI Yuejiao | 2010 | Chinese Geographical Science2010,20,6: | 7 |
| 2 | Emission of intermediate volatility organic compounds from a ship main engine burning heavy fuel oil显示文摘Intermediate volatility organic compounds(IVOCs)are crucial precursors of secondary organic aerosol(SOA).In this study,gaseous IVOCs emitted from a ship main engine burning heavy fuel oil(HFO)were investigated on a test bench,which could simulate the real-world operations and emissions of ocean-going ships.The chemical compositions,emission factors(EFs)and volatility distributions of IVOC emissions were investigated.The results showed that the main engine burning HFO emitted a large amount of IVOCs,with average IVOC EFs of 20.2-201 mg/kg-fuel.The IVOCs were mainly comprised of unspeciated compounds.The chemical compositions of exhaust IVOCs were different from that of HFO fuel,especially for polycyclic aromatic compounds and alkylcyclohexanes.The volatility distributions of IVOCs were also different between HFO exhausts and HFO fuel.The distinctions in IVOC emission characteristics between HFO exhausts and HFO fuel should be considered when assessing the IVOC emission and related SOA formation potentials from ocean-going ships burning HFO,especially when using fuel-surrogate models. | Haijun Lou Yuejiao Hao Weiwei Zhang Penghao Su Fan Zhang Yingjun Chen Daolun Feng Yifan Li | 2019 | Journal of Environmental Sciences2019,31,10: | 5 |
| 3 | Photoluminescence Properties of Porous Silicon Based on FZ(H) Si Wafer显示文摘The photoluminescence (PL) properties of porous silicon (PS) have been studied based on n-type single- crystal (111) silicon wafers (80-90Ω .cm in the resistivity). The porous silicon layers (PSL) were created by anodizing the wafers with a denuded zone of 20-40 μm formed by neutron transmutation doping (NTD) and thermal treatment at 940℃ for 4 h and then 700℃ for 2 h, two-step heating of the floating-zone silicon (FZ Si) grown in a hydrogen (H2) ambience. By surface modification with stannic chloride or amine immersion and rapid thermal oxidation (RTO), the PL peak position from the PS can be qualitatively controlled factitiously. The as-prepared PS shows an orange-yellow luminescence, while the modified samples emit red, green and blue luminescence. Mechanisms for the different colors of the PL are discussed. Fourier transform infrared (FTIR) is carried out to analyze the differences in the structural configuration of the PS samples. | Yuejiao He, Huaixiang Li, Chenghua Guo, Guirong Liu, Yansheng Chen, Shuzhen Duan (Institute of Semiconductors, Shandong Normal University, Jinan 250014, China Metallurgy School, University of Science and Technology Beijing, Beijing 100083, China) | 2001 | Rare Metals2001,20,1: | 2 |
| 4 | Analysis of transportation carbon emissions and its potential for reduction in China显示文摘The transportation industry is an essential sector for carbon emissions mitigation.This paper firstly used the LMDI(Logarithmic Mean Divisia Index)decomposition method to establish factors decomposition model on China's transportation carbon emission.Then,a quantitative analysis was performed to study the factors influencing China's transportation carbon emissions from 1991 to 2008,which are identified as transportation energy efficiency,transportation structure and transportation development.The results showed that:(1)The impact of transportation development on transportation carbon emissions showed pulling function.Its contribution value to carbon emissions remained at high growth since 1991 and showed an exponential growth trend.(2)The impact of transportation structure on transportation carbon emissions showed promoting function in general,but its role in promoting carbon emissions decreased year by year.And with the continuous optimization of transportation structure,the promoting effect decreased gradually and showed the inversed'U'trend.(3)The impact of transportation energy efficiency on transportation carbon emissions showed a function of inhibition before pulling.In order to predict the potential of carbon emission reduction,three scenarios were set.Analysis of the scenarios showed that if greater intensity emission reduction measures are taken,the carbon emissions will reduce by 31.01 million tons by 2015 and by 48.81 million tons by 2020. | Jinxue Ding Fengjun Jin Yuejiao Li Jiao'e Wang | 2013 | Chinese Journal of Population,Resources and Environment2013,11,1: | 2 |
| 5 | Emissions of intermediate volatility organic compound from waste cooking oil biodiesel and marine gas oil on a ship auxiliary engine显示文摘Ship auxiliary engines contribute large amounts of air pollutants when at berth.Biodiesel,including that from waste cooking oil(WCO),can favor a reduction in the emission of primary pollutant when used with internal combustion engines.This study investigated the emissions of gaseous intermediate-volatile organic compounds(IVOCs)between WCO biodiesel and marine gas oil(MGO)to further understand the differences in secondary organic aerosol(SOA)production of exhausts.Results revealed that WCO exhaust exhibited similar IVOC composition and volatility distribution to MGO exhaust,despite the differences between fuel contents.While WCO biodiesel could reduce IVOC emissions by 50%as compared to MGO,and thus reduced the SOA production from IVOCs.The compositions and volatility distributions of exhaust IVOCs varied to those of their fuels,implying that fuel-component-based SOA predicting model should be used with more cautions when assessing SOA production of WCO and MGO exhausts.WCO biodiesel is a cleaner fuel comparing to conventional MGO on ship auxiliary engines with regard to the reductions in gaseous IVOC emissions and corresponding SOA productions.Although the tests were conducted on test bench,the results could be considered as representative due to the widely applications of the test engine and MGO fuel on real-world ships. | Penghao Su Yuejiao Hao Zhe Qian Weiwei Zhang Jing Chen Fan Zhang Fang Yin Daolun Feng Yingjun Chen Yifan Li | 2020 | Journal of Environmental Sciences2020,32,5: | 2 |

| 7 | Organosilicon-group-derived silica-ionogel electrolyte for lithium ion batteries显示文摘In order to avoid leakage problem caused by liquid electrolyte, a new ionogel electrolyte was developed by in situ immobilizing organosilicon-functionalized ionic liquid within a nanoporous silica matrix. The ionic liquid evenly coats on the surface of porous silica and fills in the silica framework pores with no strong chemical interaction.The ionogel electrolyte has the dual advantages of a silica solid support and a wide electrochemical stability window of ionic liquid(4.87 V vs. Li^+/Li). The half-cells assembled with this electrolyte and LiFePO_4 electrode have excellent performance at room temperature and 60 ℃. The Li/SiO_2-IGE/LiFePO_4 cell displays a discharge capacity of 129.1 mAh·g^(-1) after 200 charge/discharge cycles at room temperature. | YueJiao Li Cui Guo LuShan Yue WenJie Qu Nan Chen YuJuan Dai RenJie Chen Feng Wu | 2018 | Rare Metals2018,37,6: | 1 |
| 8 | Highly Sensitive Pseudocapacitive Iontronic Pressure Sensor with Broad Sensing Range显示文摘Flexible pressure sensors are unprecedentedly studied on monitoring human physical activities and robotics.Simultaneously,improving the response sensitivity and sensing range of flexible pressure sensors is a great challenge,which hinders the devices’practical application.Targeting this obstacle,we developed a Ti_(3)C_(2)T_(x)-derived iontronic pressure sensor(TIPS)by taking the advantages of the high intercalation pseudocapacitance under high pressure and rationally designed structural configuration.TIPS achieved an ultrahigh sen-sitivity(S_(min)>200 kPa^(−1),S_(max)>45,000 kPa^(−1))in a broad sensing range of over 1.4 MPa and low limit of detection of 20 Pa as well as stable long-term working durability for 10,000 cycles.The practical application of TIPS in physical activity monitoring and flexible robot manifested its versatile potential.This study provides a demonstration for exploring pseudocapacitive materials for building flexible iontronic sensors with ultrahigh sensitivity and sensing range to advance the development of high-performance wearable electronics. | Libo Gao Meng Wang Weidong Wang Hongcheng Xu Yuejiao Wang Haitao Zhao Ke Cao Dandan Xu Lei Li | 2021 | Nano-Micro Letters2021,13,9: | 1 |
| 9 | Intact Polar and Core Tetraether Lipids in Sediments from the Haiyang 4 Cold-seep of the Northern South China Sea and their Implications显示文摘A number of cold seeps have been discovered in the northern South China Sea(SCS) including the Haiyang 4 cold-seep area where Core 973-5 was collected. Intact polar lipids(IPLs) and core lipids(CLs) were analyzed separately in sediments from Core 973-5. The most abundant lipid biomarkers were isoprenoidal GDGTs(iso GDGTs), with Crenarchaeol and GDGT-0 predominating. IPL-iso GDGTs and CL-iso GDGTs were mainly derived from Thaumarchaeota. IPL-iso GDGTs were mainly produced and retained in situ thus containing most of the in situ microbiological information. Branched GDGTs were predominantly derived from generated in marine production, and mixed with some terrestrial inputs. All IPLs groups presented a high value in the sulfate-methane transition zone(SMTZ). Furthermore, IPL and CL-MI, IPL-R;showed the highest values within the SMTZ, while IPL and CL-R;had the lowest values at the SMTZ, suggesting that the contribution of Methanophila and methanogenic to GDGTs increased, while the contribution of ammonia-oxidizing Archaea to GDGTs decreased at the SMTZ. | LI Yuejiao SU Xin JIAO Lu CHEN Fang CHENG Sihai | 2022 | Acta Geologica Sinica(English Edition)2022,96,2: | 1 |
| 10 | A gradient solid electrolyte interphase with high Li+conductivity induced by bisfluoroacetamide additive for stable lithium metal batteries显示文摘Stable Li metal anodes have become the driving factor for high-energy-density battery systems.However,uncontrolled growth of Li dendrite hinders the application of rechargeable Li metal batteries(LMBs).Here,a multifunctional electrolyte additive bisfluoroacetamide(BFA)was proposed to facilitate high-performance LMBs.The uniform and dense deposition of Li^(+) was achieved due to the reduced nucleation and plateau overpotential by the addition of BFA.Moreover,X-ray photoelectron spectroscopy(XPS)tests reveal a gradient solid electrolyte interface(SEI)structure on the Li metal surface.Cyclic voltammetry(CV)curves at different sweep speeds prove the formation of pseudocapacitance at the electrode-electrolyte interface,which accelerates the Li+transport rate and protects the electrode structure.The low activation energy also indicates the ability of rapid Li^(+) transportation in electrolyte bulk.Therefore,the Li||Li symmetric cells with 1.0 wt.%BFA electrolyte exhibit good cycling performance at 0.5 mA·cm^(−2)for over 2000 h,and Li||LiNi_(0.6)Co_(0.2)Mn_(0.2)O_(2)(NCM622)full cells maintain a high capacity for 200 cycles at 1 C rate. | Zhaoyang Sun Ziyue Wen Yi Chen Yue Ma Jinxiang Zhang Yuejiao Li Li Li Renjie Chen | 2023 | Nano Research2023,16,6: | 0 |
| 11 | Fast ion diffusion alloy layer facilitating 3D mesh substrate for dendrite-free zinc-ion hybrid capacitors显示文摘Although aqueous zinc ion hybrid capacitors have advantageous integration of batteries and supercapacitors,they still suffer from the inherent problems of dendrite growth and interfacial side reactions on Zn anodes.Herein,a universal fast zinc-ion diffusion layer on a three-dimensional(3 D)mesh structure model is demonstrated to effectively improve Zn plating/stripping reversibility.The fast ion diffusion alloy layer accelerates the Zn^(2+)migration in an orderly manner to homogenize Zn^(2+)flux and overcomes the defects of the commercial mesh substrate,effectively avoiding dendrite growth and side reactions.Consequently,the proof-of-concept silver-zinc alloy modified stainless steel mesh delivers superb reversibility with the high coulombic efficiency over 99.4%at 4 mA cm^(-2)after 1600 cycles and excellent reliability of over 830 h at 1 mA cm^(-2),Its feasibility is also evidenced in commercial zinc ion hybrid capacitors with activated carbon as the cathode.This work enriches the fundamental comprehension of fast zinc-ion diffusion layer combined with a 3 D substrate on the Zn deposition and opens a universal approach to design advanced host for Zn electrodes in zinc ion hybrid capacitors. | Huaming Yu Quanyu Li Wen Liu Han Wang Xuyan Ni Qiwen Zhao Weifeng Wei Xiaobo Ji Yuejiao Chen Libao Chen | 2022 | Journal of Energy Chemistry2022,31,10: | 0 |

| 13 | Regulating surface electron structure of PtNi nanoalloy via boron doping for high‐current‐density Li‐O2 batteries with low overpotential and long‐life cyclability显示文摘The realization of high‐efficiency,reversible,stable,and safe Li‐O2 batteries is severely hindered by the large overpotential and side reactions,especially at high rate conditions.Therefore,rational design of cathode catalysts with high activity and stability is crucial to overcome the terrible issues at high current density.Herein,we report a surface engineering strategy to adjust the surface electron structure of boron(B)‐doped PtNi nanoalloy on carbon nanotubes(PtNiB@CNTs)as an efficient bifunctional cathodic catalyst for high‐rate and long‐life Li‐O2 batteries.Notably,the Li‐O2 batteries assembled with as‐prepared PtNiB@CNT catalyst exhibit ultrahigh discharge capacity of 20510 mA·h/g and extremely low overpotential of 0.48 V at a high current density of 1000 mA/g,both of which outperform the most reported Pt‐based catalysts recently.Meanwhile,our Li‐O2 batteries offer excellent rate capability and ultra‐long cycling life of up to 210 cycles at 1000 mA/g under a fixed capacity of 1000 mA·h/g,which is two times longer than those of Pt@CNTs and PtNi@CNTs.Furthermore,it is revealed that surface engineering of PtNi nanoalloy via B doping can efficiently tailor the electron structure of nanoalloy and optimize the adsorption of oxygen species,consequently delivering excellent Li‐O2 battery performance.Therefore,this strategy of regulating the nanoalloy by doping nonmetallic elements will pave an avenue for the design of high‐performance catalysts for metal‐oxygen batteries. | Yajun Ding Yuanchao Huang Yuejiao Li Tao Zhang Zhong‐Shuai Wu | 2024 | SmartMat2024,5,1: | 0 |

| 15 | Stretchable and anti-impact iontronic pressure sensor with an ultrabroad linear range for biophysical monitoring and deep learning-aided knee rehabilitation显示文摘Monitoring biophysical signals such as body or organ movements and other physical phenomena is necessary for patient rehabilitation.However,stretchable flexible pressure sensors with high sensitivity and a broad range that can meet these requirements are still lacking.Herein,we successfully monitored various vital biophysical features and implemented in-sensor dynamic deep learning for knee rehabilitation using an ultrabroad linear range and highsensitivity stretchable iontronic pressure sensor(SIPS).We optimized the topological structure and material composition of the electrode to build a fully stretching on-skin sensor.The high sensitivity(12.43 kPa^(−1)),ultrabroad linear sensing range(1 MPa),high pressure resolution(6.4 Pa),long-term durability(no decay after 12000 cycles),and excellent stretchability(up to 20%)allow the sensor to maintain operating stability,even in emergency cases with a high sudden impact force(near 1 MPa)applied to the sensor.As a practical demonstration,the SIPS can positively track biophysical signals such as pulse waves,muscle movements,and plantar pressure.Importantly,with the help of a neuro-inspired fully convolutional network algorithm,the SIPS can accurately predict knee joint postures for better rehabilitation after orthopedic surgery.Our SIPS has potential as a promising candidate for wearable electronics and artificial intelligent medical engineering owing to its unique high signal-to-noise ratio and ultrabroad linear range. | Hongcheng Xu Libo Gao Haitao Zhao Hanlin Huang Yuejiao Wang Gang Chen Yuxin Qin Ningjuan Zhao Dandan Xu Ling Duan Xuan Li Siyu Li Zhongbao Luo Weidong Wang Yang Lu | 2021 | Microsystems & Nanoengineering2021,7,6: | 0 |
| 16 | Experimental and theoretical studies on NO selective catalytic oxidation over α-MnO_(2)显示文摘Based on the experimental and theoretical methods,the NO selective catalytic oxidation process was proposed.The experimental results indicated that lattice oxygen was the active site for NO oxide over the α-MnO_(2)(110) surface.In the theoretical study,DFT (density functional theory) and periodic slab modeling were performed on an α-MnO_(2)(110) surface,and two possible NO oxidation mechanisms over the surface were proposed.The non-defectα-MnO_(2)(110) surface showed the highest stability,and the surface Os(the second layer oxygen atoms) position was the most active and stable site.O_(2)molecule enhanced the joint adsorption process of two NO molecules.The reaction process,including O_(2)dissociation and O=N-O-O-N=O formation,was calculated to carry out the NO catalytic oxidation mechanism over α-MnO_(2)(110).The results showed that NO oxidation over the α-MnO_(2)(110) surface exhibited the greatest possibility following the route of O=N-O-O-N=O formation.Meanwhile,the formation of O=N-O-O-N=O was the rate-determining step. | Xingguang Hao Jie Yang Xin Sun Ping Ning Kai Li Yuan Li Yuejiao Hao Xin Song | 2023 | Journal of Environmental Sciences2023,,4: | 0 |
| 17 | Multiple regulatory roles of the transfer RNA-derived small RNAs in cancers显示文摘With the development of sequencing technology,transfer RNA(tRNA)-derived small RNAs(tsRNAs)have received extensive attention as a new type of small noncoding RNAs.Based on the differences in the cleavage sites of nucleases on tRNAs,tsRNAs can be divided into two categories,tRNA halves(tiRNAs)and tRNA-derived fragments(tRFs),each with specific subcellular localizations.Additionally,the biogenesis of tsRNAs is tissue-specific and can be regulated by tRNA modifications.In this review,we first elaborated on the classification and biogenesis of tsRNAs.After summarizing the latest mechanisms of tsRNAs,including transcriptional gene silencing,post-transcriptional gene silencing,nascent RNA silencing,translation regulation,rRNA regulation,and reverse transcription regulation,we explored the representative biological functions of tsRNAs in tumors.Furthermore,this review summarized the clinical value of tsRNAs in cancers,thus providing theoretical support for their potential as novel biomarkers and therapeutic targets. | Yu Zhang Xinliang Gu Yang Li Yuejiao Huang Shaoqing Ju | 2024 | Genes & Diseases2024,11,2: | 0 |
