| 1 | A highly selective catalyst of Co/La_(4)Ga_(2)O_(9) for CO_(2) hydrogenation to ethanol显示文摘A new catalyst of Co/La_(4)Ga_(2)O_(9) for CO_(2) hydrogenation to produce ethanol was prepared by reducing LaCo^(0).5 Ga0.5 O3,which showed excellent selectivity to ethanol(%35 C-mol%)at mild reaction conditions(270°C,3.5 MPa,3000 m L g-1 h-1).The catalysts were characterized by N_(2) adsorption/desorption,XRD,XAFS,CO and CO_(2)-TPD,H2 chemisorption,XPS and TEM techniques.The interaction between Co nanoparticles(NPs)and La2+4 Ga_(2)O_(9) oxide resulted in Co^(0)-Coon the surface of Co NPs.It was proposed that La_(4)Ga_(2)O_(9) could catalyze reverse water gas shift reaction(r-WGS),which converted CO_(2) to CO.Then,the CO migrated to Co^(0)-Co^(2+)on Co NPs,where it was hydrogenated to form ethanol like higher alcohols synthesis from syngas.The results suggest that by controlling the oxidation state of cobalt,and combined with a kind of active site for activating CO_(2) to form CO,a catalyst with excellent selectivity to ethanol could be obtained for CO_(2) hydrogenation,which means that the complex reaction may be proceed with high selectivity using only one active metal component. | Kang An Siran Zhang Jiaming Wang Qiang Liu Ziyang Zhang Yuan Liu | 2021 | Journal of Energy Chemistry2021，30，5： | 3 |
| 2 | Enhanced biodegradation of chlorobenzene via combined Fe^(3+) and Zn^(2+) based on rhamnolipid solubilisation显示文摘Biotrickling filters(BTFs) for hydrophobic chlorobenzene(CB) purification are limited by mass transfer and biodegradation. The CB mass transfer rate could be improved by 150 mg/L rhamnolipids. This study evaluated the combined use of Fe^(3+) and Zn^(2+) to enhance biodegradation in a BTF over 35 day. The effects of these trace elements were analysed under different inlet concentrations(250, 600, 900, and 1200 mg/L) and empty bed residence times(EBRTs;60, 45, and 32 sec). Batch experiments showed that the promoting effects of Fe^(3+)/Zn^(2+) on microbial growth and metabolism were highest for 3 mg/L Fe^(3+) and 2 mg/L Zn^(2+), followed by 2 mg/L Zn^(2+), and lowest at 3 mg/L Fe^(3+). Compared to BTF in the absence of Fe^(3+) and Zn^(2+), the average CB elimination capacity and removal efficiency in the presence of Fe^(3+) and Zn^(2+) increased from 61.54 to 65.79 g/(m 3 hr) and from 80.93% to 89.37%, respectively, at an EBRT of 60 sec. The average removal efficiency at EBRTs of 60, 45, and 32 sec increased by 2.89%, 5.63%, and 11.61%, respectively. The chemical composition(proteins(PN), polysaccharides(PS)) and functional groups of the biofilm were analysed at 60, 81, and 95 day. Fe^(3+) and Zn^(2+) significantly enhanced PN and PS secretion, which may have promoted CB adsorption and biodegradation. High-throughput sequencing revealed the promoting effect of Fe^(3+) and Zn^(2+) on bacterial populations. The combination of Fe^(3+) and Zn^(2+) with rhamnolipids was an efficient method for improving CB biodegradation in BTFs. | Na Liu Dan Li Kang Li Liping Wang Ruiwei Xu Jiaming Zhang Bairen Yang | 2021 | Journal of Environmental Sciences2021，33，5： | 2 |
| 3 | The nucleocapsid protein of rice stripe virus in cell nuclei of vector insect regulates viral replication显示文摘Rice stripe virus(RSV)transmitted by the small brown planthopper causes severe rice yield losses in Asian countries.Although viral nuclear entry promotes viral replication in host cells,whether this phenomenon occurs in vector cells remains unknown.Therefore,in this study,we systematically evaluated the presence and roles of RSV in the nuclei of vector insect cells.We observed that the nucleocapsid protein(NP)and viral genomic RNAs were partially transported into vector cell nuclei by utilizing the importin a nuclear transport system.When blocking NP nuclear localization,cytoplasmic RSV accumulation significantly increased.In the vector cell nuclei,NP bound the transcription factor YY1 and affected its positive regulation to FAIM.Subsequently,decreased FAIM expression triggered an antiviral caspase-dependent apoptotic reaction.Our results reveal that viral nuclear entry induces completely different immune effects in vector and host cells,providing new insights into the balance between viral load and the immunity pressure in vector insects. | Wan Zhao Junjie Zhu Hong Lu Jiaming Zhu Fei Jiang Wei Wang Lan Luo Le Kang Feng Cui | 2022 | Protein & Cell2022，13，5： | 2 |
| 4 | A composite of Ni-Fe-Zn layered double hydroxides/biochar for atrazine removal from aqueous solution显示文摘This study assembled corn stalk-derived biochar(BC)with layered double hydroxide(LDH)through a rapid coprecipitation of biochar and metal(Ni/Fe/Zn)hydroxide precipitates.A BC and LDH composite(BC-LDH)and modified BC-LDH material after heating(BC-LDH-P)were prepared successfully for atrazine adsorptive removal.The physicochemical properties of the synthesized samples were analyzed by X-ray diffraction(XRD),scanning electron microscopy(SEM),Fourier transform infrared(FT-IR),and X-ray photoelectron spectroscopy(XPS).Batch experiments were conducted to study the sorption of atrazine onto BC,BC-LDH,and BC-LDH-P from the aqueous solution.The adsorption of atrazine onto BC-LDH and BC-LDH-P were performed following with the pseudo-second-order kinetic model,and the sorption isotherms agreed well with the Freundlich fitting model.The adsorption amounts of the three materials are arranged in descending order is as follows:BC-LDH-P>BC-LDH>BC(143.15>123.10>95.93 mg g−1,respectively).Due to the high crystallinity of the LDH material and the high binding degree with biochar,Ni/Fe/Zn-LDH biochar composites offer a potential alternative to a carbon-based adsorbent for atrazine removal from aqueous solution. | Yifan Wang Jiaming Kang Simeng Jiang Hui Li Zheyi Ren Qinbo Xu Qun Jiang Wenzhu Liu Ruizhen Li Ying Zhang | 2020 | Biochar2020，2，4： | 2 |
| 5 | Sub-nanometer ultrathin epitaxy of AlGaN and its application in efficient doping显示文摘Solving the doping asymmetry issue in wide gap semiconductors is a key dificulty and long-standing challenge for device applications.Here,a desorption-tailoring strategy is proposed to juggle the carrier concentration and transport.Specific to the p-doping issue in Al-rich AlGaN,self-assembled p-AlGaN superlattices with an average Al composition of over 50%are prepared by adopting this approach.The hole concentration as high as 8.1×10^(18)cm^(-3)is thus realized at room temperature,which is attributed to the signifcant reduction of effective Mg activation energy to 17.5 meV through modulating the activating path,as well as the highlighted Mg surface-incorporation by an intentional interruption for desorption.More importantly,benefting from the constant ultrathin barrier thickness of only three monolayers via this approach,vertical miniband transport of holes is verifed in the p-AlGaN superlattices,greatly satisfying the demand of hole injection in device application.280 nm deep-ultraviolet light emitting diodes are then fabricated as a demo with the desorption-tailored Al-rich p-AlGaN superlattices,which exhibit a great improvement of the carrier injection efficiency and light extraction efficiency,thus leading to a 55.7%increase of the light output power.This study provides a solution for p-type doping of Al-rich AlGaN,and also sheds light on solving the doping asymmetry issue in general for wide-gap semiconductors. | Jiaming Wang Mingxing Wang Fujun Xu Baiyin Liu Jing Lang Na Zhang Xiangning Kang Zhixin Qin Xuelin Yang Xinqiang Wang Weikun Ge Bo Shen | 2022 | Light(Science & Applications)2022，11，4： | 1 |
| 6 | Progress in efficient doping of Al-rich AlGaN显示文摘The development of semiconductors is always accompanied by the progress in controllable doping techniques.Taking AlGaN-based ultraviolet(UV)emitters as an example,despite a peak wall-plug efficiency of 15.3%at the wavelength of 275 nm,there is still a huge gap in comparison with GaN-based visible light-emitting diodes(LEDs),mainly attributed to the inefficient doping of AlGaN with increase of the Al composition.First,p-doping of Al-rich AlGaN is a long-standing challenge and the low hole concentration seriously restricts the carrier injection efficiency.Although p-GaN cladding layers are widely adopted as a compromise,the high injection barrier of holes as well as the inevitable loss of light extraction cannot be neglected.While in terms of n-doping the main issue is the degradation of the electrical property when the Al composition exceeds 80%,resulting in a low electrical efficiency in sub-250 nm UV-LEDs.This review summarizes the recent advances and outlines the major challenges in the efficient doping of Al-rich AlGaN,meanwhile the corresponding approaches pursued to overcome the doping issues are discussed in detail. | Jiaming Wang Fujun Xu Lisheng Zhang Jing Lang Xuzhou Fang Ziyao Zhang Xueqi Guo Chen Ji Chengzhi Ji Fuyun Tan Xuelin Yang Xiangning Kang Zhixin Qin Ning Tang Xinqiang Wang Weikun Ge Bo Shen | 2024 | Journal of Semiconductors2024，45，2： | 0 |
