| 5 | Electronic structure and chemical reaction of Ca deposition on regioregular poly(3-hexylthiophene) surfaces显示文摘Conjugated polymer, regioregular poly(3-hexylthiophene) (rr-P3HT), films were prepared by spin-coating the rr-P3HT chloroform solution onto clean silicon wafer surfaces. The chemical re-action and electronic structure of Ca deposition on rr-P3HT surfaces were in situ investigated by synchrotron radiation photoemission spectroscopy (SRPES) and X-ray photoemission spectros-copy (XPS). Upon Ca deposition, Ca-induced band bending of rr-P3HT is observed. In addition, Ca atoms preferentially react with S atoms of rr-P3HT. No obvious reaction between Ca and C atoms can be found. Through the investigation of the evolution of valence band spectra and secondary electron cut-off of rr-P3HT during the process of Ca deposition, an energy level alignment diagram at the Ca/rr-P3HT interface is derived. | ZHAO Wei GUO YuXian FENG XueFei ZHANG Liang ZHANG WenHua ZHU JunFa | 2009 | Chinese Science Bulletin2009,54,11: | 3 |

| 7 | Sirt1-ROS-TRAF6 Signaling-Induced Pyroptosis Contributes to Early Injury in Ischemic Mice显示文摘Stroke is an acute cerebro-vascular disease with high incidence and poor prognosis,most commonly ischemic in nature.In recent years,increasing attention has been paid to inflammatory reactions as symptoms of a stroke.However,the role of inflammation in stroke and its underlying mechanisms require exploration.In this study,we evaluated the inflammatory reactions induced by acute ischemia and found that pyroptosis occurred after acute ischemia both in vivo and in vitro,as determined by interleukin-1β,apoptosis-associated speck-like protein,and caspase-1.The early inflammation resulted in irreversible ischemic injury,indicating that it deserves thorough investigation.Meanwhile,acute ischemia decreased the Sirtuin 1(Sirtl)protein levels,and increased the TRAF6(TNF receptor associated factor 6)protein and reactive oxygen species(ROS)levels.In further exploration,both Sirtl suppression and TRAF6 activation were found to contribute to this pyroptosis.Reduced Sirtl levels were responsible for the production of ROS and increased TRAF6 protein levels after ischemic exposure.Moreover,N-acetyl-L-cysteine,an ROS scavenger,suppressed the TRAF6 accumulation induced by oxygen-glucose deprivation via suppression of ROS bursts.These phenomena indicate that Sirtl is upstream of ROS,and ROS bursts result in increased TRAF6 levels.Further,the activation of Sirtl during the period of ischemia reduced ischemiainduced injury after 72 h of reperfusion in mice with middle cerebral artery occlusion.In sum,these results indicate that pyroptosis-dependent machinery contributes to the neural injury during acute ischemia via the Sirt1-ROS-TRAF6 signaling pathway.We propose that inflammatory reactions occur soon after oxidative stress and are detrimental to neuronal survival;this provides a promising therapeutic target against ischemic injuries such as a stroke. | Weijie Yan Wei Sun Jiahui Fan Haiqing Wang Song Han Junfa Li Yanling Yin | 2020 | Neuroscience Bulletin2020,36,8: | 9 |

| 9 | Organic solvent-and phase transfer catalyst-free oxidation of cyclohexanol to cyclohexanone with dilute H_2O_2显示文摘The oxidation of cyclohexanol to cyclohexanone with 30% aqueous hydrogen peroxide by using peroxotung-state complexes formed in situ from sodium tungstate di-hydrate and various bidentate organic ligands as the catalysts, without organic solvents, halide and phase transfer catalyst has been carried out. The influence of 13 ligands on the oxidation is investigated. The maximum yield of cyclohexanone is obtained when using 1,10-phenanthroline (96%) and oxalic acid (95%) as the ligand. Very high yields (around 90%) have also been obtained for the instances of using salicylic acid, 3,5-dibromosalicylic acid, and 8-hydro- xylquino-line as ligands. A research to improve the reaction condition using cheap oxalic acid as the ligand indicates that the optimum condition is that the reaction mixture with a molar ratio of cycohexanol:tungstate dihydrate:oxalic acid: 30% H2O2=100:2:2:120 was stirred at 85-90℃ for 12 h. | WEI Junfa, SHI Xianying, HE Diping & ZHANG MinSchool of Chemistry and Material Science, Shaanxi Normal University, Xi’an 710062, China | 2002 | Chinese Science Bulletin2002,47,24: | 3 |
| 10 | Alkali ion-promoted palladium subnanoclusters stabilized on porous alumina nanosheets with enhanced catalytic activity for benzene oxidation显示文摘Catalytic C−H bond activation is one of the backbones of the chemical industry.Supported metal subnanoclusters consisting of a few atoms have shown attractive properties for heterogeneous catalysis.However,the creation of such catalyst systems with high activity and excellent anti-sintering ability remains a grand challenge.Here,we report on alkali ion-promoted Pd subnanoclusters supported over defectiveγ-Al_(2)O_(3) nanosheets,which display exceptional catalytic activity for C−H bond activation in the benzene oxidation reaction.The presence of Pd subnanoclusters is verified by aberration-corrected high-angle annular dark-field scanning transmission electron microscopy,X-ray absorption spectroscopy,and X-ray photoelectron spectroscopy.This catalyst shows excellent catalytic activity,with a turnover frequency of 280 h^(−1) and yield of 98%,in benzene oxidation reaction to give phenol under mild conditions.Moreover,the introduction of alkali ion greatly retards the diffusion and migration of metal atoms when tested under high-temperature sintering conditions.Density functional theory(DFT)calculations reveal that the addition of alkali ion to Pd nanoclusters can significantly impact the catalyst’s structure and electronic properties,and eventually promote its activity and stability.This work sheds light on the facile and scalable synthesis of highly active and stable catalyst systems with alkali additives for industrially important reactions. | Zhijun Li Minghui Di Wei Wei Leipeng Leng Zhijun Li Cheng He Qiang Tan Qian Xu J.Hugh Horton Li Li Junfa Zhu | 2022 | Nano Research2022,15,7: | 1 |

| 14 | Fabrication of oxygen-doped MoSe2 hierarchical nanosheets for highly sensitive and selective detection of trace trimethylamine at room temperature in air显示文摘Nano Research volume 13,pages1704–1712(2020)Cite this article 191 Accesses Metrics details Abstract Intelligent gas sensors based on the layered transition metal dichalcogenides(TMDs)have attracted great interest in the field of gas sensing due to their multiple active sites,fast electron,mass transfer capability and large surface-to-volume ratio.However,conventional TMDs-based sensors typically work at elevated temperature in inert atmosphere,which would largely limit the corresponding practical applications.Herein,novel oxygen-doped MoSe2 hierarchical nanostructures composed of ultrathin nanosheets with large specific surface area have been designed and generated typically at 200°C in air for fast and facile gas sensing of trimethylamine(TMA),effectively.Benefited from the gas-accessible hierarchical morphology and high surface area with abundant nanochannels,highly sensitive and selective detection of trace TMA has been achieved under ambient condition,and as detected the theoretical limit of detection(LOD)is 8 ppb,which is the lowest for TMA detection under ambient condition among the reported studies.The mechanism of oxygen doping on the improved gas-sensing performance has been investigated,revealing that the oxygen doping could greatly optimize the electronic structure,thus regulate the Fermi level of MoSe2 as well as the affinity between TMA molecule and sensor surface.It is expected that the oxygen doping strategy developed for the highly efficient gas sensors based on TMDs in present work may also be applicable to other types of gas-sensing semiconductors,which could open up a new direction for the rational design of high-performance gas sensors working under ambient condition. | Nannan Hou Qianqian Sun Jing Yang Su You Yun Cheng Qian Xu Wei Li Shiqi Xing Li Zhang Junfa Zhu Qing Yang | 2020 | Nano Research2020,13,6: | 0 |
| 15 | An in-situ spectroscopy investigation of alkali metal interaction mechanism with the imide functional group显示文摘Organic anode materials have attracted considerable interest owing to their high tunability by adopting various active functional groups.However,the interaction mechanisms between the alkali metals and the active functional groups in host materials have been rarely studied systematically.Here,a widely used organic semiconductor of perylene-3,4,9,10-tetracarboxylic diimide(PTCDI)was selected as a model system to investigate how alkali metals interact with imide functional groups and induce changes in chemical and electronic structures of PTCDI.The interaction at the alkali/PTCDI interface was probed by in-situ X-ray photoelectron spectroscopy(XPS),ultraviolet photoelectron spectroscopy(UPS),synchrotron-based near edge X-ray absorption fine structure(NEXAFS),and corroborated by density functional theory(DFT)calculations.Our results indicate that the alkali metal replaces the hydrogen atoms in the imide group and interact with the imide nitrogen of PTCDI.Electron transfer induced gap states and downward band-bending like effects are identified on the alkali-deposited PTCDI surface.It was found that Na shows a stronger electron transfer effect than Li.Such a model study of alkali insertion/intercalation in PTCDI gives insights for the exploration of the potential host materials for alkali storage applications. | Xu Lian Zhirui Ma Zhonghan Zhang Jinlin Yang Shuo Sun Chengding Gu Yuan Liu Honghe Ding Jun Hu Xu Cao Junfa Zhu Shuzhou Li Wei Chen | 2020 | Nano Research2020,13,12: | 0 |
