1Variation in cis-regulation of a NAC transcription factor contributes to drought tolerance in wheat显示文摘Drought is a major environmental factor limiting wheat production worldwide,and developing drought-tolerant cultivars is a central challenge for wheat breeders globally.Therefore,it is important to identify genetic components determining drought tolerance in wheat.In this study,we identified a wheat NAC gene(TaNAC071-A)that is tightly associated with drought tolerance by a genome-wide association study.Knockdown of TaNAC071-A in wheat attenuated plant drought tolerance,whereas its overexpression significantly enhanced drought tolerance through improved water-use efficiency and increased expression of stress-responsive genes.This heightened water-saving mechanism mitigated the yield loss caused by water deficit.Further candidate gene association analysis showed that a 108-bp insertion in the promoter of TaNAC071-A alters its expression level and contributes to variation in drought tolerance among wheat accessions.This insertion contains two MYB cis-regulatory elements(CREs)that can be directly bound by the MYB transcription activator,TaMYBL1,thereby leading to increased TaNAC071-A expression and plant drought tolerance.Importantly,introgression of this 108-bp insertion allele,TaNAC071-AIn-693,into drought-sensitive cultivars could improve their drought tolerance,demonstrating that it is a valuable genetic resource for wheat breeding.Taken together,our findings highlight a major breakthrough in determining the genetic basis underlying phenotypic variation in wheat drought tolerance and showcase the potential of exploiting CRE-containing indels for improving important agronomical traits.Hude Mao Shumin Li Bin Chen Chao Jian Fangming Mei Yifang Zhang Fangfang Li Nan Chen Tian Li Linying Du Li Ding Zhongxue Wang Xinxiu Cheng Xiaojing Wang Zhensheng Kang 2022Molecular Plant2022,15,2:9
2Research on prediction model of formation temperature of ammonium bisulfate in air preheater of coal-fired power plant显示文摘Ammonium bisulfate(ABS)is a viscous compound produced by the escape NH_(3) in the NO reduction process and SO_(3) in the flue gas at a certain temperature,which can cause the ash corrosion of the air preheater in coal-fired power plants.Therefore,it is essential to study the formation temperature of ABS to prevent the deposition of ABS in air preheaters.In this paper,the SO_(3) reaction kinetic model is used to analyze the SO_(3) generation process from coal combustion to the selective catalytic reduction(SCR)exit stage,and the kinetic model of NO reduction is used to analyze the NH_(3) escape process.A prediction model for calculating the ABS formation temperature based on the S content in coal and NO reduction parameters of the SCR is proposed,solving the difficulty of measuring SO_(3) concentration and NH_(3) concentration in the previous calculation equation of ABS formation temperature.And the reliability of the model is verified by the actual data of the power plant.Then the influence of S content in coal,NH_(3)/NO_(x) molar ratio,different NO_(x) concentrations at SCR inlet,and NO removal efficiency on the formation temperature of ABS are analyzed.Kai Zhang Fangming Xue Zhiqiang Wang Xingxing Cheng 2022Chinese Journal of Chemical Engineering2022,35,8:2
3Electrodeposition of Pt-Decorated Ni(OH)_(2)/CeO_(2) Hybrid as Superior Bifunctional Electrocatalyst for Water Splitting显示文摘The facile synthesis of highly active and stable bifunctional electrocatalysts to catalyze water splitting is attractive but challenging.Herein,we report the electrodeposition of Pt-decorated Ni(OH)_(2)/CeO_(2)(PNC)hybrid as an efficient and robust bifunctional electrocatalyst.The graphite-supported PNC catalyst delivers superior hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)activities over the benchmark Pt/C and RuO_(2),respectively.For overall water electrolysis,the PNC hybrid only requires a cell voltage of 1.45V at 10mAcm-2 and sustains over 85 h at 1000mAcm^(-2).The remarkable HER/OER performances are attributed to the superhydrophilicity and multiple effects of PNC,in which Ni(OH)_(2)and CeO_(2)accelerate HER on Pt due to promoted water dissociation and strong electronic interaction,while the electron-pulling Ce cations facilitate the generation of high-valence Ni OER-active species.These results suggest the promising application of PNC for H2 production from water electrolysis.Huanhuan Liu Zhenhua Yan Xiang Chen Jinhan Li Le Zhang Fangming Liu Guilan Fan Fangyi Cheng 2020Research2020,,1:2

5Anionic formulation of electrolyte additive towards stable electrocatalytic oxygen evolution in seawater splitting显示文摘Hydrogen generation through seawater electrolysis provides a promising,attractive pathway towards the utilization of sustainable energy.However,the catalytic activity and stability of oxygen evolution anode are severely limited by the chloride-induced corrosion and competitive oxidation reactions.In this work,we demonstrate an anion-assisted performance improvement strategy by quick and universal screening of electrolyte additive via correlating Cl-repellency with the anionic properties.Particularly,the addition of phosphate ions is found to enable highly stable alkaline seawater splitting at industry-level current density(0.5 A cm^(-2))over 500 h using transition metal hydroxides as anodic electrocatalysts.In situ experiments and theoretical simulations further reveal that the dynamic anti-corrosion behaviors of surface-adsorbed phosphate ions are attributed to three factors including repelling Cl-ions without significantly blocking OH-diffusion,preventing transition metal dissolution and acting as a local pH buffer to compensate the fast OH-consumption under high current electrolysis.Meng Yu Jinhan Li Fangming Liu Jiuding Liu Wence Xu Honglu Hu Xijie Chen Weichao Wang Fangyi Cheng 2022Journal of Energy Chemistry2022,31,9:1
6The Electrochemical Tuning of Transition Metal-Based Materials for Electrocatalysis显示文摘The development of clean and sustainable energy depends largely on electrocatalysis-driven technologies.Because of this,tremendous efforts have been devoted to the search for efficient electrocatalysts to reduce the overpotential and increase the selectivity of electrochemical reactions.Of the various approaches,electrochemical tuning is seen as a promising tech-nique to controllably tune the properties of catalytic materials under mild conditions.Based on this,this review will present representative electrochemical tuning methodologies involving insertion and conversion reactions in batteries as well as in situ electrode modulation during electrocatalysis processes.This review will first provide an introduction of electrochemi-cal tuning strategies from the perspective of reactions and devices.Subsequently,this review will present comprehensive discussions on recent advancements in the modulation of various electrocatalyst properties,including electronic structure,crystalline phase,lattice strain and dimensional size,all of which significantly impact corresponding intrinsic activity and active site exposure.This review will also highlight the merits,challenges and issues of electrochemical tuning and propose promising directions in the exploration of corresponding methods in the design and enhancement of electrocatalysts for future energy applications.Fangming Liu Le Zhang Lei Wang Fangyi Cheng 2021Electrochemical Energy Reviews2021,4,1:1
7SARS-CoV-2-specific immune response in COVID-19 convalescent individuals显示文摘We collected blood from coronavirus disease 2019(COVID-19)convalescent individuals and investigated SARS-CoV-2-specific humoral and cellular immunity in these discharged patients.Follow-up analysis in a cohort of 171 patients at 4-11 months after the onset revealed high levels of IgG antibodies.A total of 78.1%(164/210)of the specimens tested positive for neutralizing antibody(NAb).SARS-CoV-2 antigen peptide pools-stimulated-IL-2 and-IFN-y response can distinguish COVID-19 convalescent individuals from healthy donors.Interestingly,NAb survival was significantly affected by the antigen peptide pools-stimulated-IL-2 response,-IL-8 response,and-IFN-y response.The antigen peptide pools-activated CD8+T cell counts were correlated with NAb.The antigen peptide pools-activated natural killer(NK)cell counts in convalescent individuals were correlated with NAb and disease severity.Our data suggested that the development of NAb is associated with the activation of T cells and NK cells.Our work provides a basis for further analysis of the protective immunity to SARS-CoV-2 and for understanding the pathogenesis of COVID-19.It also has implications for the development of an effective vaccine for SARS-CoV-2 infection.Yunbao Pan Xianghu Jiang Liu Yang Liangjun Chen Xiaojiao Zeng Guohong Liu Yueting Tang Chungen Qian Xinming Wang Fangming Cheng Jun Lin Xinghuan Wang Yirong Li 2021Signal Transduction and Targeted Therapy2021,6,8:0
8Ni_(3)S_(2)@NiFePx electrode with dual-anion-modulated layer for efficient and stable oxygen evolution显示文摘The rational construction of high-performance and stable electrocatalyst for oxygen evolution reaction(OER)is a prerequisite for efficient water electrolysis.Herein,we develop a broccoli-like Ni_(3)S_(2)@NiFeP_(x)(Ni_(3)S_(2)@NFP)catalyst on nickel foam(NF)via a sequential two-step layer-by-layer assembly electrodeposition method.X-ray diffraction,in situ Raman and Fourier-transform infrared spectra have mutually validated the element segregation and phase refusion during OER condition.The reconstruction of double layer Ni_(3)S_(2)@NFP facilitates the formation of the active(oxy)hydroxides,which is modulated by the dual anionic layer with mixed sulfate and phosphate ions.As a result,the obtained Ni_(3)S_(2)@NFP electrode exhibits low overpotential(329 mV)and long-term durability(∼500 h)for OER at current density of 500mA/cm^(2).Moreover,the self-supported Ni_(3)S_(2)@NFP can act as an efficient and durable anode in alkaline anion exchange membrane water electrolysis device(AEMWE).This work provides a facile and scaled-up strategy to construct self-supported electrocatalyst and emphasizes the crucial role of anions in pre-catalyst reconstruction and enhancing OER performance.Xijie Chen Keqiang Xu Jinhan Li Xiao Wang Tete Zhao Fangming Liu Meng Yu Fangyi Cheng 2023Chinese Chemical Letters2023,34,11:0

10Revealing the GHG reduction potential of emerging biomass-based CO_(2) utilization with an iron cycle system显示文摘CO_(2) utilization becomes a promising solution for reducing anthropogenic greenhouse gas (GHG) emissions. Biomass-based CO_(2) utilization (BCU) even has the potential to generate negative emissions, but the corresponding quantitative evaluation is limited. Herein, the biomass-based CO_(2) utilization with an iron cycle (BCU-Fe) system, which converts CO_(2) into formate by Fe under hydrothermal conditions and recovers Fe with biomass-derived glycerin, was investigated. The GHG reduction potential under various process designs was quantified by a multidisciplinary method, including experiments, simulations, and an ex-ante life-cycle assessment. The results reveal that the BCU-Fe system could bring considerable GHG emission reduction. Significantly, the lowest value is −34.03 kg CO_(2)-eq/kg absorbed CO_(2) (−2.44 kg CO_(2)-eq/kg circulated Fe) with the optimal yield of formate (66%) and Fe (80%). The proposed ex-ante evaluation approach not only reveals the benefits of mitigating climate change by applying the BCU-Fe system, but also serves as a generic tool to guide the industrialization of emerging carbon-neutral technologies.Jing Xu Jiong Cheng Runtian He Jiaqi Lu Chunling Wang Heng Zhong Fangming Jin 2023Frontiers of Environmental Science & Engineering2023,17,10:0
