1Decomposition and decoupling analysis of carbon dioxide emissions in African countries during 1984–2014显示文摘The potential for mitigating climate change is growing worldwide,with an increasing emphasis on reducing CO_(2)emissions and minimising the impact on the environment.African continent is faced with the unique challenge of climate change whilst coping with extreme poverty,explosive population growth and economic difficulties.CO_(2)emission patterns in Africa are analysed in this study to understand primary CO_(2)sources and underlying driving forces further.Data are examined using gravity model,logarithmic mean divisia index and Tapio's decoupling indicator of CO_(2)emissions from economic development in 20 selected African countries during 1984-2014.Results reveal that CO_(2)emissions increased by 2.11%(453.73 million ton)over the research period.Gravity centre for African CO_(2)emissions had shifted towards the northeast direction.Population and economic growth were primary driving forces of CO_(2)emissions.Industrial structure and emission efficiency effects partially offset the growth of CO_(2)emissions.The economic growth effect was an offset factor in central African countries and Zimbabwe due to political instability and economic mismanagement.Industrial structure and emission efficiency were insufficient to decouple economic development from CO_(2)emissions and relieve the pressure of population explosion on CO_(2)emissions in Africa.Thus,future efforts in reducing CO_(2)emissions should focus on scaleup energy-efficient technologies,renewable energy update,emission pricing and long-term green development towards sustainable development goals by 2030.Claudien Habimana Simbi Jianyi Lin Dewei Yang Jean Claude Ndayishimiye Yang Liu Huimei Li Lingxing Xu Weijing Ma 2021Journal of Environmental Sciences2021,33,4:3
2Acute systemic accumulation of acrolein in mice by inhalation at a concentration similar to that in cigarette smoke显示文摘Cigarette smoke is an important environmental factor associated with a wide array of public health concerns. Acrolein, a component of tobacco smoke and a known toxin to various cell types, may be a key pathological factor mediating the adverse effects linked with tobacco smoke. Although acrolein is known to accumulate in the respiratory system after acute nasal exposure, it is not clear if it accumulates systemically, and less is known in the nervous system. The aim of this study was to assess the degree of acrolein accumulation in the circulation and in the spinal cord following acute acrolein inhalation in mice. Using a laboratory-fabricated inhalation chamber, we found elevated urinary 3-HPMA, an acrolein metabolite, and increased acrolein adducts in the spinal cord after weeks of nasal exposure to acrolein at a concentration similar to that in tobacco smoke. The data indicated that acrolein is absorbed into the circulatory system and some enters the nervous system. It is expected that these findings may facilitate further studies to probe the pathological role of acrolein in the nervous system resulting from smoke and other external sources.Melissa Tully Lingxing Zheng Glen Acosta Ran Tian Riyi Shi 2014Neuroscience Bulletin2014,30,6:2

4Probing the active sites of 2D nanosheets with Fe-N-C carbon shell encapsulated Fe_(x)C/Fe species for boosting sodium-ion storage performances显示文摘Developing stable but high active metal-nitrogen-carbon(M-N-C)-based hard carbon anode is a promising way to be the alternatives to graphene and blank hard carbon for sodium-ion batteries(SIBs),requiring the precise tailoring of the electronic structure for optimizing the Na+intercalation behavior,yet is greatly challenging.Herein,Fe-N-C graphitic layer-encapsulating Fe3C species within hard carbon nanosheets(Fe-N-C/Fe3C@HCNs)are rationally engineered by pyrolysis of self-assembled polymer.Impressively,the Fe-N-C/Fe3C@HCNs exhibit outstanding rate capacity(242 mAh·g^(−1)at 2,000 mA·g^(−1)),which is 2.1 and 4.2 times higher than that of Fe-N-C and N-doped carbon(N-C),respectively,and prolonged cycling stability(176 mAh·g^(−1)at 2,000 mA·g^(−1)after 2,000 cycles).Theoretical calculations unveil that the Fe3C species enhance the electronic transfer from Na to Fe-N-C,resulting in the charge redistribution between the interfaces of Fe3C and Fe-N-C.Thus,the optimized adsorption behavior towards Na+reduces the thermodynamic energy barriers.The synergistic effect of Fe3C and Fe-N-C species maintains the structural integrity of electrode materials during the sodiation/desodiation process.The in-depth insight into the advanced Na+storage mechanisms of Fe3C@Fe-N-C offers precise guidance for the rational establishment of confinement heterostructures in SIBs.Huicong Xia Pengfei Yuan Lingxing Zan Gan Qu Yunchuan Tu Kaixin Zhu Yifan Wei Zeyu WeiFangying Zheng Mo Zhang Yongfeng Hu Dehui Deng Jianan Zhang 2022Nano Research2022,15,8:1

7Extraordinarily stable and wide-temperature range sodium/potassium-ion batteries based on 1D SnSe2-SePAN composite nanofibers显示文摘Developing electrodes with long lifespan and wide-temperature adaptability is crucial important to achieve high-performance sodium/potassium-ion batteries(SIBs/PIBs).Herein,the SnSe2-SePAN composite was fabricated for extraordinarily stable and wide-temperature range SIBs/PIBs through a coupling strategy between controllable electrospinning and selenylation,in which SnSe2 nanoparticles were uniformly encapsulated in the SePAN matrix.The unique structure of SnSe2-SePAN not only relieves drastic volume variation but also guarantees the structural integrity of the composite,endowing SnSe2-SePAN with excellent sodium/potassium storage properties.Consequently,SnSe2-SePAN displays a high sodium storage capacity and excellent feasibility in a wide working temperature range(-15 to 60℃:300 mAh g^(-1)/700 cycles/-15℃;352 mAh g^(-1)/100 cycles/60℃at 0.5 A g^(-1)).At room temperature,it delivers a record-ultralong cycling life of 192 mAh g^(-1)that exceeds 66000 cycles even at 15 A g^(-1).It exhibits extremely superb electrochemical performance in PIBs(157 mAh g^(-1)exceeding 15000 cycles at 5 A g^(-1)).The ex situ XRD and TEM results attest the conversion-alloy mechanism of SnSe2-SePAN.Also,computational calculations verify that SePAN takes an important role in intensifying the electrochemical performance of SnSe2-SePAN electrode.Therefore,this study breaks new ground on solving the polyselenide dissolution issue and improving the wide temperature workable performance of sodium/potassium storage.Yiyi Wang Fuyu Xiao Xi Chen Peixun Xiong Chuyuan Lin Hong-En Wang Mingdeng Wei Qingrong Qian Qinghua Chen Lingxing Zeng 2023InfoMat2023,5,9:1

9Influences of the Great Whirl on surface chlorophyll a concentration off the Somali Coast in 2017显示文摘The general features of the Great Whirl(GW)off the Somali Coast in 2017 and its influences on chlorophyll a(Chl a)concentration were studied by using satellite data and model outputs.Results show that GW,which initiated at7°N,53°E on June 13,had a lifetime of 153 d with an average amplitude of 16 cm and an average radius of 205 km.After the formation of GW,the concentration of Chl a in the interior of GW showed a downward trend throughout its life cycle,except in early July and mid-October.In early July,the Chl a blooms in the interior of GW were attributed to the combined effect of three processes.They are eddy horizontal transportation,the deepening of the mixed layer caused by the monsoon and eddy pumping,and the upward transportation of nutrients caused by eddy-induced Ekman pumping.In October,the Chl a blooms were probably due to the weakening of GW.During the period,water exchange occurred more frequently across the eddy,thus phytoplanktons were imported into the interior of GW.Lingxing Dai Bing Han Shilin Tang Chuqun Chen Yan Du 2021Acta Oceanologica Sinica2021,40,11:0

12Mechanism of interfacial effects in sodium-ion storage devices显示文摘Rechargeable sodium-ion batteries(SIBs)are considered as the next-generation secondary batteries.The performance of SIB is determined by the behavior of its electrode surface and the electrode–electrolyte interface during charging and discharging.Thus,the characteristics of these surfaces and interfaces should be analyzed to realize large-scale energy storage systems with high energy density and long-cycle stability.Although various studies have investigated the properties of electrode materials,few studies have focused on the construction of stable and efficient SIB interfaces,and even fewer have explored the mechanisms of interfacial effects;however,the strategies of regulating interfacial effects are yet to be completely developed.Moreover,the results obtained thus far are insufficient to draw systematic conclusions.The present study reviews the literature on the mechanism of interfacial effects in Na+storage devices.The interfaces in a sodium-ion storage device include a heterogeneous interface between electrode materials,a solid electrolyte interphase,and a cathode electrolyte interphase.The interfacial effects during the intercalation,transformation,and alloy reactions and the resulting overall battery performance were theoretically analyzed.In this review,we aim to provide a theoretical basis for optimizing the structures of electrode surface and electrode–electrolyte interface to optimize the performance of SIBs.In addition,the challenges of investigating interfacial effects and several possible helpful methods and opportunities for studying the mechanisms of interfacial effects in SIBs will be presented.Yifan Wei Lingxing Zan Huicong Xia Wenfu Yan Jia-Nan Zhang 2024Nano Research2024,17,3:0
13Roles and implications of mRNA N^(6)-methyladenosine in cancer显示文摘RNA N^(6)-methyladenosine modification is the most prevalent internal modification of eukaryotic RNAs and has emerged as a novel field of RNA epigenetics,garnering increased attention.To date,m^(6)A modification has been shown to impact multiple RNA metabolic processes and play a vital role in numerous biological processes.Recent evidence suggests that aberrant m^(6)A modification is a hallmark of cancer,and it plays a critical role in cancer development and progression through multiple mechanisms.Here,we review the biological functions of mRNA m^(6)A modification in various types of cancers,with a particular focus on metabolic reprogramming,programmed cell death and tumor metastasis.Furthermore,we discuss the potential of targetingm^(6)Amodification or its regulatory proteins as a novel approach of cancer therapy and the progress of research on m^(6)A modification in tumor immunity and immunotherapy.Finally,we summarize the development of different m^(6)A detection methods and their advantages and disadvantages.Lingxing Zeng Xudong Huang Jialiang Zhang Dongxin Lin Jian Zheng 2023Cancer Communications2023,43,7:0
14Antioxidant induced bulk passivation for efficient and stable hole transport layer-free carbon electrode perovskite solar cells显示文摘Defect passivation is one of the important strategies to improve the efficiency and stability of perovskite solar cells.In this work,2,6-di-tert-butyl-4-methylphenol(BHT)as antioxidant was introduced into the perovskite precursor solution to improve the quality of the prepared perovskite films,so that these films performed a larger and uniform grain size.Moreover,the-OH functional group in BHT interacts with I-,thus reducing the density of defect states and inhibiting the non-radiative recombination.The presence of hydrophobic groups in BHT protects the film from moisture erosion and improves the long-term stability of PSCs devices.The maximum photoelectric conversion efficiency of the constructed ITO/SnO_(2)/BHTMAPbI_(3)/Carbon device is 16.88%,and the unpackaged cell maintains the initial efficiency of 99.3%after698 h of storage under the environmental condition of 30%humidity.This work provides an efficient approach to improve the performance of printable hole transport layer-free carbon electrode perovskite solar cells.Yetai Cheng Qingbo Wei Nannan Wang Zhangwen Ye Yanbin Zhao Qiongyao Wang Depeng Chu Lingxing Zan Feng Fu Yucheng Liu 2023Chinese Chemical Letters2023,34,6:0
15Progress in Electrolyte Engineering of Aqueous Batteries in a Wide Temperature Range显示文摘Aqueous rechargeable batteries are safe and environmentally friendly and can be made at a low cost;as such,they are attracting attention in the field of energy storage.However,the temperature sensitivity of aqueous batteries hinders their practical application.The solvent water freezes at low temperatures,and there is a reduction in ionic conductivity,whereas it evaporates rapidly at high temperatures,which causes increased side reactions.This review discusses recent progress in improving the performance of aqueous batteries,mainly with respect to electrolyte engineering and the associated strategies employed to achieve such improvements over a wide temperature domain.The review focuses on fi ve electrolyte engineer-ing(aqueous high-concentration electrolytes,organic electrolytes,quasi-solid/solid electrolytes,hybrid electrolytes,and eutectic electrolytes)and investigates the mechanisms involved in reducing the solidifi cation point and boiling point of the electrolyte and enhancing the extreme-temperature electrochemical performance.Finally,the prospect of further improving the wide temperature range performance of aqueous rechargeable batteries is presented.Lingjun He Chuyuan Lin Peixun Xiong Hui Lin Wenbin Lai Jingran Zhang Fuyu Xiao Liren Xiao Qingrong Qian Qinghua Chen Lingxing Zeng 2023Transactions of Tianjin University2023,29,5:0
16Direct conversion of N_(2) and O_(2):status,challenge and perspective显示文摘As key components of air,nitrogen(N_(2))and oxygen(O_(2))are the vital constituents of lives.Synthesis of NO_(2),and C-N-O organics direct from N_(2) and O_(2),rather than from an intermediate NH_(3)(known as the Haber-Bosch process),is tantalizing.However,the extremely strong N≡N triple bond(945 kJ mol-1)and the nonpolar stable electron configuration of dinitrogen lead to its conversion being extensively energy demanding.The further selective synthesis of high-value C-N-O organics directly from N_(2),O_(2) and C-containing molecules is attractive yet greatly challenging from both scientific and engineering perspectives.Enormous efforts have been dedicated to the direct conversion of N2 and O2 via traditional and novel techniques,including thermo chemical,plasma,electrochemical,ultrasonic and photochemical conversion.In this review,we aim to provide a thorough comprehension of the status and challenge of the direct conversion of N2,O2 and C-containing molecules(particularly N2 and O2).Moreover,we will propose some future perspectives to stimulate more inspiration from the scientific community to tackle the scientific and engineering challenges.Di Li Lingxing Zan Shiming Chen Zhang-Jie Shi Ping Chen Zhenfeng Xi Dehui Deng 2022National Science Review2022,9,12:0
