3Rush-hour aromatic and chlorinated hydrocarbons in selected subway stations of Shanghai,China显示文摘Air samples were collected simultaneously at platform,mezzanine and outdoor in five typical stations of subway system in Shanghai,China using stainless steel canisters and analyzed by gas chromatography-mass selective detector (GC-MSD) after cryogenic pre-concentration.Benzene,toluene,ethylbenzene and xylenes (BTEX) at the platforms and mezzanines inside the stations averaged (10.3±2.1),(38.7±9.0),(19.4±10.1) and (30.0±11.1) μg/m 3,respectively;while trichloroethylene (TrCE),tetrachloroethylene (TeCE) and para-dichlorobenzene (pDCB),vinyl chloride and carbon tetrachloride were the most abundant chlorinated hydrocarbons inside the stations with average levels of (3.6±1.3),(1.3±0.5),(4.1±1.1),(2.2±1.1) and (1.2±0.3) μg/m 3,respectively.Mean levels of major aromatic and chlorinated hydrocarbons were higher indoor (platforms and mezzanines) than outdoor with average indoor/outdoor (I/O) ratios of 1.1-9.5,whereas no significant indoor/outdoor differences were found except for benzene and TrCE.The highly significant mutual correlations (p<0.01) for BTEX between indoor and outdoor and their significant correlation (p<0.05) with methyl tert-butyl ether (MTBE),a marker of traffic-related emission without other indoor and outdoor sources,indicated that BTEX were introduced into the subway stations from indoor/outdoor air exchange and traffic emission should be their dominant source.TrCE and pDCB were mainly from indoor emission and TeCE might have both indoor emission sources and contribution from outdoor air,especially in the mezzanines.Yanli Zhang Chunlei Li Xinming Wang Hai Guo Yanli Feng Jianmin Chen 2012Journal of Environmental Sciences2012,24,1:6
4A flexible carbon nanotube@V_(2)O_(5) film as a high-capacity and durable cathode for zinc ion batteries显示文摘Aqueous zinc-ion batteries(ZIBs)are receiving a continuously increasing attention for mobile devices,especially for the flexible and wearable electronics,due to their non-toxicity,non-flammability,and low-cost features.Despite the significant progress in achieving higher capacities for electrode materials of ZIBs,to endow them with high flexibility and economic feasibility is,however,still a significant challenge remaining unsolved.Herein,we present a highly flexible composite film composed of carbon nanotube film and V_(2)O_(5)(CNTF@V_(2)O_(5))with high strength and high conductivity,which is prepared by simply impregnating a porous CNT film with an aqueous V_(2)O_(5)sol under vacuum.For this material,intimate incorporation between V_(2)O_(5)and CNTs has been achieved,successfully integrating the high zinc ion storage capability with high mechanical flexibility.As a result,this CNTF@V_(2)O_(5)film delivers a high capacity of 356.6 m Ah g^(-1)at 0.4 A g^(-1)and excellent cycling stability with 80.1%capacity retention after 500 cycles at 2.0 A g^(-1).The novel strategy and the outstanding battery performance presented in this work should shed light on the development of high-performance and flexible ZIBs.Xiaowei Wang Liqun Wang Bao Zhang Jianmin Feng Jiafeng Zhang Xing Ou Feng Hou Ji Liang 2021Journal of Energy Chemistry2021,30,8:5
5Transition metal carbides in electrocatalytic oxygen evolution reaction显示文摘Oxygen evolution reaction(OER) is admitted to an important half reaction in water splitting for sustainable hydrogen production.The sluggish four-electron process is known to be the bottleneck for enhancing the efficiency of OER.In this regard,tremendous efforts have been devoted to developing effective catalysts for OER.In addition to Ir-or Ru-based oxides taken as the benchmark,transition metal carbides have attracted ever-increasing interest due to the high activity and stability as low-cost OER electrocatalysts.In this review,the transition metal carbides for water oxidation electrocatalysis concerning design strategies and synthesis are briefly summarized.Some typical applications for various carbides are also highlighted.Besides,the development trends and outlook are also discussed.Huaping Wang Sheng Zhu Jiwei Deng Wenchao Zhang Yuezhan Feng Jianmin Ma 2021Chinese Chemical Letters2021,32,1:5
6Electrospun Sb2Se3@C nanofibers with excellent lithium storage properties显示文摘Antimony-based materials have become promising anodes within lithium-ion batteries(LIBs)due to their low cost and the high theoretical capacity.However,there is a potential to further enhance the electrochemical performance of such antimony-based materials.Herein,Sb2Se3@C nanofibers(Sb2Se3@CNFs)are designed and obtained via a novel electrospinning method.Upon electrochemically testing as an anode within LIBs,the Sb2Se3@CNFs(annealed at 600℃)delivers a remarkably good cycling performance of 625 mAh/g at 100 mA/g after 100 cycles.Moreover,it still remains at 490 mAh/g after 500 cycles with an applied current density of 1.0 A/g.The excellent performance of the Sb2 Se3@CNFs can be attributed to the fact that the N-doped C matrices not only remit the volume expansion of materials,but also enhance the electrical and ionic conductivity thusly increasing the lithium-ion diffusion.The obtained Sb2Se3@CNFs are promising anode for LIBs in the future.Yan Dong Yuezhan Feng Jiwei Deng Pengbin He Jianmin Ma 2020Chinese Chemical Letters2020,31,3:4
7Different surface modification methods and coating materials of zinc metal anode显示文摘Rechargeable aqueous Zn-ion batteries(AZIBs)are one of the most promising energy storage devices for large-scale energy storage owing to their high specific capacity,eco-friendliness,low cost and high safety.Nevertheless,zinc metal anodes suffer from severe dendrite growth and side reactions,resulting in the inferior electrochemical performance of AZIBs.To address these problems,surface modification of zinc metal anodes is a facile and effective method to regulate the interaction between the zinc anode and an electrolyte.In this review,the current challenges and strategies for zinc metal anodes are presented.Furthermore,recent advances in surface modification strategies to improve their electrochemical performance are concluded and discussed.Finally,challenges and prospects for future development of zinc metal anodes are proposed.We hope this review will be useful for designing and fabricating highperformance AZIBs and boosting their practical applications.Feng Tao Yong Liu Xinyuan Ren Jing Wang Yazhou Zhou Yingjie Miao Fengzhang Ren Shizhong Wei Jianmin Ma 2022Journal of Energy Chemistry2022,31,3:4
8Defective ZnS nanoparticles anchored in situ on N-doped carbon as a superior oxygen reduction reaction catalyst显示文摘Defect engineering has been used to develop low-cost and effective catalysts to boost oxygen reduction reactions.However,the development of catalysts that use metal cation vacancies as the active sites for oxygen reduction reaction is lacking.In this study,ZnS nanoparticles on N-doped carbon serve as an oxygen reduction reaction catalyst.These catalysts were prepared via a one-step method at 900℃.Amazingly,the high-resolution transmission electron microscope image revealed obvious defects in the ZnS nanoparticles.These facilitated the catalyst synthesis,and the product displayed good electrocatalytic performance for the oxygen reduction reaction in an alkaline medium,including a lower onset potential,lower mid-wave potential,four electron transfer process,and better durability compared with 20 wt%Pt/C.More importantly,the density functional theory results indicated that using the Zn vacancies in the prepared catalyst as active sites required a lower reaction energy to produce OOH*from*OO toward oxygen reduction reaction.Therefore,the proposed catalyst with Zn vacancies can be used as a potential electrocatalyst and may be substitutes for Pt-based catalysts in fuel cells,given the novel catalyst’s resulting performance.Libing Hu Zengxi Wei Feng Yu Huifang Yuan Mincong Liu Gang Wang Bangfiua Peng Bin Dai Jianmin Ma 2019Journal of Energy Chemistry2019,28,12:3
9Fe, V-co-doped C_(2)N for electrocatalytic N_(2)-to-NH_(3) conversion显示文摘Designing providential catalyst is the key to drive the electrochemical nitrogen reduction reactions(NRR),which is referring to multiple intermediates and products. By means of density functional theory(DFT)calculations, we studied heteronuclear bi-atom electrocatalyst(HBEC) for NRR. Our results revealed that compared to homonuclear bi-atom electrocatalyst(Fe_2@C_2N, V_2@C_2N), Fe, V-co-doped C_2N(Fe V@C_2N)had a smaller limiting potential of-0.17 V and could accelerate N_2-to-NH_3 conversion through the enzymatic pathway of NRR. Importantly, N–N bond length monotonically increases with increasing the Bader charges of adsorbed N_2 molecule but decreases with increasing the Bader charge difference of two adsorbed N atoms. Additionally, the Fe V@C_2N could suppress the production of H_2 by the preferential adsorption and reduction of N_2 molecule. Thus, the as-designed HBEC may have the outstanding electrochemical NRR performance. This work opens a new perspective for NRR by HBECs under mild conditions.Zengxi Wei Jian He Yulu Yang Zhenhai Xia Yuezhan Feng Jianmin Ma 2021Journal of Energy Chemistry2021,30,2:3
102020 Roadmap on two-dimensional nanomaterials for environmental catalysis显示文摘Environmental catalysis has drawn a great deal ofattention due to its clean ways to produce useful chemicals or carry out some chemical processes.Photocatalysis and electrocatalysis play important roles in these fields.They can decompose and remove organic pollutants from the aqueous environment,and prepare some fine chemicals.Moreover,they also can carry out some important reactions,such as 02 reduction reaction(ORR),O2 evolution reaction(OER),H2 evolution reaction(HER),CO2 reduction reaction(C02 RR),and N2 fixation(NRR).For catalytic reactions,it is the key to develop high-performance catalysts to meet the demand fortargeted reactions.In recentyears,two-dimensional(2 D) materials have attracted great interest in environmental catalysis due to their unique layered structures,which offer us to make use of their electronic and structural characteristics.Great progress has been made so far,including graphene,black phosphorus,oxides,layered double hydroxides(LDHs),chalcogenides,bismuth-based layered compounds,MXenes,metal organic frameworks(MOFs),covalent organic frameworks(COFs),and others.This content drives us to invite many famous groups in these fields to write the roadmap on two-dimensional nanomaterials for environmental catalysis.We hope that this roadmap can give the useful guidance to researchers in future researches,and provide the research directions.Yulu Yang Mingguang Wu Xingwang Zhu Hui Xu Si Ma Yongfeng Zhi Hong Xia Xiaoming Liu Jun Pan Jie-Yinn Tang Siang-Piao Chai Leonardo Palmisano Francesco Parrino Junli Liu Jianzhong Ma Ze-Lin Wang Ling Tan Yu-Fei Zhao Yu-Fei Song Pardeep Singh Pankaj Raizada Deli Jiang Di Li R.A.Geioushy Jizhen Ma Jintao Zhang Song Hu Rongjuan Feng Gang Liu Minghua Liu Zhenhua Li Mingfei Shao Neng Li Jiahe Peng Wee-Jun Ong Nikolay Kornienko Zhenyu Xing Xiujun Fan Jianmin Ma 2019Chinese Chemical Letters2019,30,12:2
11Weak magnetic field accelerates chromate removal by zero-valent iron显示文摘Weak magnetic field(WMF) was employed to improve the removal of Cr(VI) by zero-valent iron(ZVI) for the first time. The removal rate of Cr(VI) was elevated by a factor of 1.12–5.89 due to the application of a WMF, and the WMF-induced improvement was more remarkable at higher Cr(VI) concentration and higher p H. Fe2+was not detected until Cr(VI) was exhausted, and there was a positive correlation between the WMF-induced promotion factor of Cr(VI) removal rate and that of Fe2+release rate in the absence of Cr(VI) at pH 4.0–5.5. These phenomena imply that ZVI corrosion with Fe2+release was the limiting step in the process of Cr(VI) removal. The superimposed WMF had negligible influence on the apparent activation energy of Cr(VI) removal by ZVI, indicating that WMF accelerated Cr(VI)removal by ZVI but did not change the mechanism. The passive layer formed with WMF was much more porous than without WMF, thereby facilitating mass transport. Therefore,WMF could accelerate ZVI corrosion and alleviate the detrimental effects of the passive layer, resulting in more rapid removal of Cr(VI) by ZVI. Exploiting the magnetic memory of ZVI, a two-stage process consisting of a small reactor with WMF for ZVI magnetization and a large reactor for removing contaminants by magnetized ZVI can be employed as a new method of ZVI-mediated remediation.Pian Feng Xiaohong Guan Yuankui Sun Wonyong Choi Hejie Qin Jianmin Wang Junlian Qiao Lina Li 2015Journal of Environmental Sciences2015,27,5:2

13Co-doped graphene edge for enhanced N2-to-NH3 conversion显示文摘N2 fixation in atmosphere is an important issue in modern chemistry.Designing an ideal electrochemical nitrogen reduction reaction(NRR)catalyst to overcome the sluggish reaction kinetic and ultralow selectivity is still the significant challenge.Herein,we screened the potential catalyst to accelerate N2 fixation by designing the single transition metal(TM)atoms(Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn,Mo,W,Ru and Rh)supported on the edge of graphene.Our calculations revealed that the Co atom supported on the graphene edge could selectively stabilize*N2 H species and destabilize*NH2 species,leading to the highest catalytic activity and selectivity for N2 fixation at the ambient conditions.In addition,the enzymatic mechanism of eNNR have the lowest overpotential of 0.72 V.This theoretical work will give a new perspective to design an available catalyst for NRR.Zengxi Wei Yuezhan Feng Jianmin Ma 2020Journal of Energy Chemistry2020,29,9:2
14Mesencephalic astrocyte-derived neurotrophic factor reduces cell apoptosis via upregulating HSP70 in SHSY-5Y cells显示文摘Background:Mesencephalic astrocyte-derived neurotrophic factor(MANF)is a new candidate growth factor for dopaminergic neurons against endoplasmic reticulum stress(ER stress).HSP70 family,a chaperon like heat shock protein family,was proved to be involved in the MANF induced survival pathway in 6-OHDA treated SHSY-5Y cells.However,the ER stress relative transcriptome,in MANF signaling cascades is still investigated.The involvement of HSP70,a 70kd member of HSP70 family,need further to be verified.Methods:The cell apoptosis was assayed by MTT,TUNEL staining and western blot of cleaved Caspase-3.The differentially expressed genes in SHSY-5Y cells under different conditions(control,6-OHDA,6-OHDA+MANF)were investigated by RNA-seq.Expression of HSP70 was further confirmed by real-time PCR.RNAi knockdown for HSP70 was performed to investigate the role of HSP70 in the MANF signaling pathway.Results:MANF inhibits 6-OHDA-induced apoptosis in SHSY-5Y cells.Six ER stress relative genes(HSP70,GRP78,xbp-1,ATF-4,ATF-6,MAPK)were found enriched in 6-OHDA+MANF treatment group.HSP70 was the most significantly up-regulated gene under 6-OHDA+MANF treatment in SHSY-5Y cells.RNAi knockdown for HSP70 inhibits the protective effects of MANF against 6-OHDA toxicity in SHSY-5Y cells.Conclusion:MANF exerts a protective role against 6-OHDA induced apoptosis in SHSY-5Y cells via up-regulating some ER stress genes,including HSP70 family members.The HSP70 expression level plays a key role in MANFmediated survival pathway.Hui Sun Ming Jiang Xing Fu Qiong Cai Jingxing Zhang Yanxin Yin Jia Guo Lihua Yu Yun Jiang Yigang Liu Liang Feng Zhiyu Nie Jianmin Fang Lingjing Jin 2017Translational Neurodegeneration2017,6,1:2
15Hygroscopicity of ambient submicron particles in urban Hangzhou,China显示文摘In this study,hygroscopicity of size-segregated ambient submicron particles in urban Hangzhou was studied from 28th December 2009 to 18th January 2010,using a hygroscopicity-tandem differential mobility analyzer(H-TDMA).The submicron particles in Hangzhou showed a minor hygroscopic growth at 73%relative humidity(RH),and then grew significantly between 77%and 82%RH.Monomodal distribution accounted for 90%for 30 nm particles,17%for 50 nm particles,and less than 7%for particles larger than 50 nm at 82%RH.Deconvolution of the bimodal distribution indicated a less hygroscopic group and a more hygroscopic group,with the fraction of the more hygroscopic group increasing with the initial dry particle size and then remaining almost constant for accumulation mode particles.Our results imply that submicron particles in urban Hangzhou were almost entirely externally mixed,and the hygroscopic properties of ambient particles in urban Hangzhou were mainly a function of their size and chemical composition.Jiachen ZHANG Lin WANG Jianmin CHEN Shengmao FENG Jiandong SHEN Li JIAO 2011Frontiers of Environmental Science & Engineering2011,5,3:2

19Drp1-dependent remodeling of mitochondrial morphology triggered by EBV-LMP1 increases cisplatin resistance显示文摘Latent membrane protein 1(LMP1)is a major Epstein–Barr virus(EBV)-encoded oncoprotein involved in latency infection that regulates mitochondrial functions to facilitate cell survival.Recently,mitochondrial fission has been demonstrated as a crucial mechanism in oncovirus-mediated carcinogenesis.Mitochondrial dynamin-related protein 1(Drp1)-mediated mitochondrial fission has an impact on the chemoresistance of cancers.However,the mechanism by which oncogenic stress promotes mitochondrial fission,potentially contributing to tumorigenesis,is not entirely understood.The role of Drp1 in the oncogenesis and prognosis of EBV-LMP1-positive nasopharyngeal carcinoma(NPC)was determined in our study.We show that EBV-LMP1 exhibits a new function in remodeling mitochondrial morphology by activating Drp1.A high level of p-Drp1(Ser616)or a low level of p-Drp1(Ser637)correlates with poor overall survival and disease-free survival.Furthermore,the protein level of p-Drp1(Ser616)is related to the clinical stage(TNM stage)of NPC.Targeting Drp1 impairs mitochondrial function and induces cell death in LMP1-positive NPC cells.In addition,EBV-LMP1 regulates Drp1 through two oncogenic signaling axes,AMPK and cyclin B1/Cdk1,which promote cell survival and cisplatin resistance in NPC.Our findings provide novel insight into the role of EBV-LMP1-driven mitochondrial fission in regulating Drp1 phosphorylation at serine 616 and serine 637.Disruption of Drp1 could be a promising therapeutic strategy for LMP1-positive NPC.Longlong Xie Feng Shi Yueshuo Li We Li Xinfang Yu Lin Zhao Min Zhou Jianmin Hu Xiangjian Luo Min Tang Jia Fan Jian Zhou Qiang Gao Weizhong Wu Xin Zhang Weihua Liao Ann MBode Ya Cao 2020Signal Transduction and Targeted Therapy2020,5,1:1
