1Enhanced N-doping in mesoporous carbon for efficient electrocatalytic CO2 conversion显示文摘The capability of electrocatalytic reducti on of carbon dioxide(CO2)using nitrogen(N)-doped carb on strongly depe nds on the N-dopi ng level and their types.In this work,we developed a strategy to generate mesoporous N-doped carb on frameworks with tun able configurati ons and contents of N dopants,by using a secondary doping process via the treatment of N,N-dimethylformamide(DMF)solvent.The obtained mesoporous N-doped carbon(denoted as MNC-D)served as an efficient electrocatalyst for electroreduction of CO2 to CO.A high Faradaic efficiency of^92%and a partial current density for CO of-6.8 mA·cm^-2 were achieved at a potential of-0.58 V vs.RHE.Electrochemical analyses further revealed that the active sites within the N-doped carb on catalysts were the pyridinic N and defects gen erated by the DMF treatme nt,which enhan ced the activati on and adsorpti on CO2 molecules.Our study suggests a new approach to develop efficie nt carb on-based catalysts for potential scalable CO2 reduction reaction(CO2RR)to fuels and chemicals.Min Kuang Anxiang Guan Zhengxiang Gu Peng Han Linping Qian Gengfeng Zheng 2019Nano Research2019,12,9:11

3Synthesis and optical characterization of Eu^(2+),Tb^(3+)-codoped Sr_3Y(PO_4)_3 green phosphors显示文摘A series of Eu^(2+),Tb^(3+)-codoped Sr_3 Y(PO_4)_3(SYP) green phosphors were synthesized by hightemperature solid-state reaction. Several techniques, such as X-ray diffraction, UV-vis spectrum,and photoluminescence spectrum, were used to investigate the obtained phosphors. The present study investigates in detail photoluminescence excitation and emission properties, energy transfer between the two dopants, and effects of doping ions on optical band gap. SYP:0.05 Eu2+ phosphor shows an intense and broad excitation band ranging from 220 to 400 nm and exhibits a bright green emission band with CIE chromaticity coordinates(0.189, 0.359) under 350 nm excitation. Green emission of SYP:0.03 Tb3+ is intensified by codoping with Eu^(2+), and energy transfer mechanism between them is demonstrated to be a dipole-dipole interaction. Upon 350 nm excitation, SYP:Eu^(2+),Tb^(3+) phosphors exhibits two dominating bands peaking at 466 and 545 nm, which are assigned to 4 f^65 d^1→4 f^7 transition of Eu^(2+) ions and ~5 D_4→~7 F_5 transition of Tb^(3+) ions, respectively. Optimal doping concentrations of Eu^(2+) and Tb^(3+) in the SYP host are 5 mol% and 15 mol%, respectively. Results indicate that SYP:Eu^(2+),Tb^(3+) phosphors are potentially used as green-emitting phosphors for white light-emitting diodes.Anxiang Guan Zuizhi Lu Fangfang Gao Xiaoshan Zhang Huan Wang Tianjiao Huang Liya Zhou 2018Journal of Rare Earths2018,36,3:4
4Literature study on clinical treatment of facial paralysis in the last 20 years using Web of Science Comparison between rehabilitation, physiotherapy and acupuncture显示文摘BACKGROUND: Facial paralysis is defined as severe or complete loss of facial muscle motor function. OBJECTIVE: The study was undertaken to explore a bibliometric approach to quantitatively assess the research on clinical treatment of facial paralysis using key words rehabilitation, physiotherapy and acupuncture using Web of Science from 1992 to 2011. DESIGN: Bibliometric approach. DATA RETRIEVAL: A bibliometric analysis based on the publications on Web of Science was performed using such as 'facial paralysis', 'rehabilitation', 'physiotherapy' and 'acupuncture'. INCLUSIVE CRITERIA: (1) Research articles on the clinical treatment of facial paralysis using acupuncture or physiotherapy (e.g. exercise, electro-stimulation) and other rehabilitation methods; (2) researches on human and animal fundamentals, clinical trials and case reports; (3) Article types: article, review, proceedings paper, note, letter, editorial material, discussion, book chapter. (4) Publication year: 1992-2011 inclusive. Exclusion criteria: (1) Articles on the causes and diagnosis on facial paralysis; (2) Type of articles: correction; (3) Articles from following databases: all databases related to social science and chemical databases in Web of Science. MAIN OUTCOME MEASURES: (1) Overall number of publications; (2) number of publications annually; (3) number of citations received annually; (4) top cited paper; (5) subject categories of publication; (6) the number of countries in which the article is published; (7) distribution of output in journals. RESULTS: Overall population stands at 3 543 research articles addressing the clinical treatment of facial paralysis in Web of Science during the study period. There is also a markedly increase in the number of publications on the subject 'facial paralysis treatments using rehabilitation' during the first decade of the 21st century, except in 2004 and 2006 when there are perceptible drops in the number of articles published. The only other year during the study period saw such a drop is 1993. Specifically, there are 192 published articles on facial paralysis treated by rehabilitation in the past two decades, far more than the output of physiotherapy treatment. Physiotherapy treatment scored only 25 articles including acupuncture treatment, with over 80% of these written by Chinese researchers and clinicians. Ranked by regions, USA is by far the most productive country in terms of the number of publications on facial paralysis rehabilitation and physiotherapy research. Seeing from another angle, the journals that focus on otolaryngology published the most number of articles in rehabilitation and physiotherapy studies, whereas most acupuncture studies on facial paralysis were published in the alternative and complementary medicine journals. CONCLUSION: Study of facial paralysis remains an area of active investigation and innovation. Further clinical studies in humans addressing the use of growth factors or stem cells continue to successful facial nerve regeneration.Xiaoge Zhang Ling Feng Liang Du Anxiang Zhang Tian Tang 2012Neural Regeneration Research2012,7,2:4
5Spatiotemporal distribution characteristics of the fog regions in China显示文摘The spatial distribution and monthly/annual variation of foggy days in China are analyzed based on the monthly mean fog data collected from 604 observational stations for the period 1961–2000. Results show that there are six fog regions in China: the middle reaches of the Yangtze River, coastal areas, Yunnan-Guizhou Plateau, eastern Gansu–Shaanxi region, Huaihe River valley, Tianshan mountainous area and northern Xinjiang. On the whole the interannual variation trend of foggy days is descending, especially an obvious decline after the 1980s. The areas where the foggy days have obvious tendency present a southwest-northeast direction. The rising trend regions alternate with descending trend regions, forming a SE-NW directional wave structure. In general, the number of foggy days in autumn and winter is larger than in spring and summer over most fog regions. The monthly variation curves of foggy days are bimodal in the coastal area of the Yellow Sea and northern Xinjiang, and unimodal in other regions.WANG Liping CHEN Shaoyong DONG Anxiang SONG Lianchun 2006Journal of Geographical Sciences2006,16,3:3
6Aging effect on the mobility and bioavailability of copper in soil显示文摘Aging effect on the mobility and bioavailability of copper(Cu) was investigated using a spiked soil with different incubation periods from 3 to 56 d.Wheat was planted and earthworms were cultured separately in the incubated soils.The mobility of Cu in soil was evaluated by a chemical fractionation scheme and the toxicity and bioavailability were assessed by measuring the biomass and Cu concentration in tissues.Results showed that aging had a significant effect on Cu fraction distribution,of which Cu tended to incorporate from the exchangeable into more stable fractions such as the reducible and oxidisable fractions.However,aging had little effect on Cu bioavailability to wheat and earthworm.Comparing the soil being incubated for 3 d and 56 d,Cu concentration in wheat roots decreased from 14.5 to 12.8 mg/kg,and no significant changes in Cu concentration were observed in both wheat shoots and earthworms.The Cu concentration was around 2.0 and 50 mg/kg for wheat shoots and earthworms,respectively,irrespective of soil incubation time.The CaCl2-extractable Cu had a linear relationship with Cu concentration in wheat roots(R2 = 0.65,P < 0.05),but no linear relationship can be found for wheat shoots and earthworms.Biological control may be more crucial for Cu accumulation in organism than the changes in soil Cu fraction caused by aging.LU Anxiang ZHANG Shuzhen QIN Xiangyang WU Wenyong LIU Honglu 2009Journal of Environmental Sciences2009,21,2:3
7Fabrication of BaTiO_3 Inverse Opal Photonic Crystal显示文摘The colloidal crystal template or opal with a closed-packed face centered cubic (fcc) lattice, was prepared from monodisperse polystyrene (PS) spheres by gravity sedimentation. The template was used for the generation of photonic crystal. The template provided void space for infiltration of liquid precursor composed of titanium butyloxide, barium acetate, ethanol, and acetic acid. The opal composite was hydrolyzed, dried, sintered by heating for completely removing PS spheres to form BaTiO3 photonic crystals with inverse opal structure. The PS spheres were replaced by air spheres, which interconnected each other through the windows on the BaTiO3 wall. So both the BaTiO3 wall and air void constitute continuous phases.AnXIANG JianPingGAO HongKuiCHEN JiuGaoYU RuiXianLIU 2004Chinese Chemical Letters2004,15,2:3

15Quantitative Surface Plasmon Interferometry via Upconversion Photoluminescence Mapping显示文摘Direct far-field visualization and characterization of surface plasmon polaritons(SPPs)are of great importance for fundamental studies and technological applications.To probe the evanescently confined plasmon fields,one usually requires advanced near-field techniques,which is typically not applicable for real-time,high-throughput detecting or mapping of SPPs in complicated environments.Here,we report the utilization of rare-earth-doped nanoparticles to quantitatively upconvert invisible,evanescently confined SPPs into visible photoluminescence emissions for direct far-field visualization of SPPs in a complicated environment.The observed interference fringes between the SPPs and the coherent incident light at the metal surface provide a quantitative measurement of the SPP wavelength and the SPP propagating length and the local dielectric environments.It thus creates a new signaling pathway to sensitively transduce the local dielectric environment change into interference periodicity variation,enabling a new design of directly measurable,spectrometer-free optical rulers for rapid,ultrasensitive label-free detection of various biomolecules,including streptavidin and prostate-specific antigen,down to the femtomolar level.Anxiang Yin Hao Jing Zhan Wu Qiyuan He Yiliu Wang Zhaoyang Lin Yuan Liu Mengning Ding Xu Xu Zhe Fei Jianhui Jiang Yu Huang Xiangfeng Duan 2019Research2019,,1:1
