A Electrospun sensor based on modified PAN (Poly Acrylonitrile) Nano-fibers doped with Lake Red C pigment for electrochemical detection of Aflatoxin B1 in Poultry feed and serum samples

07-Oct-2015 | arash babakhanian; tahere momeneh; samineh kaki; mehran torki; sayed hossain kiaee; ehsan sadeghi; Farzad Farzad Dab ..., Analyst, 2015

In this work, a novel modified nano-fiber electrode was fabricated by doping the Lake Red C (LRC) pigment into electrospun PAN (Poly Acrylonitrile) film fiber. The techniques of cyclic voltammetry (CV), scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS) and ...


Surface doping of La ions into ZnO nanocrystals to lower the optimal working temperature for HCHO sensing properties

07-Oct-2015 | Shouqin Tian; Yupeng Zhang; Dawen Zeng; Hao Wang; Neng Li; Changsheng Xie; Chunxu Pan; Xiujian Zhao, Physical Chemistry Chemical Physics, 2015

Lowering the working temperature without sacrificing other good gas-sensing properties is of particular interest to gas sensors for an excellent performance. In this work, La surface doped ZnO nanocrystals were successfully prepared by a facile thermal treatment with lanthanum nitrate (La(NO3)3) ...


Influence of Y3+, Gd3+, and Lu3+ co-doping on the phase and luminescence properties of monoclinic Eu:LaVO4 particles

07-Oct-2015 | Rik Van Deun; Micheline D'hooge; Aleksandar Savic; Isabel Van Driessche; Kristof Van Hecke; Anna M. Kaczmarek, Dalton Transactions, 2015

Nano-sized particles of monoclinic-LaVO4 were prepared in a short reaction time of 30 minutes by employing a microwave assisted hydrothermal synthesis in the presence of glycerol, which was used both as a solvent and structure-directing agent. The tetragonal-LaVO4 is known to show strong ...


Disparate roles of doped metal ions in promoting surface oxidation of TiO2 photocatalysis

04-Oct-2015 | Author(s): Jiadong Xiao, Yongbing Xie, Hongbin Cao, Faheem Nawaz, Shanshan Zhang, Yueqiu Wang, Journal of Photochemistry and Photobiology A: Chemistry, 2015

Publication date: 15 January 2016 Source:Journal of Photochemistry and Photobiology A: Chemistry, Volume 315 Author(s): Jiadong Xiao, Yongbing Xie, Hongbin Cao, Faheem Nawaz, Shanshan Zhang, Yueqiu Wang The key standpoint favors the role of doped metal ions as electron traps in ...


New Magneto‐Optical Film of Ce,Ga:GIG with High Performance

03-Oct-2015 | Qiuping Fu, Qianrui Xu, Zhongsheng Zhao, Xiaofeng Liu, Yajun Huang, Xiaolin Hu, Naifeng Zhuang, Jianzhong Chen, Journal of the American Ceramic Society, 2015

Ce3+‐doped Gd3Fe5O12 (Ce:GIG) film has a good application prospect in the field of integrated optical device. In this article, Ce:GIG and Ce,Ga:GIG films were deposited onto the quartz glass substrate by using radio‐frequency magnetron sputtering technology. The crystal phase, surface ...


From Impurity Doping to Metallic Growth in Diffusion Doping: Properties and Structure of Silver-Doped InAs Nanocrystals

02-Oct-2015 | Yorai Amit; Yuanyuan Li; Anatoly I. Frenkel; Uri Banin, ACS Nano, 2015

Tuning of the electronic properties of presynthesized colloidal semiconductor nanocrystals (NCs) by doping plays a key role in the prospect of implementing them in printed electronics devices such as transistors and photodetectors. While such impurity doping reactions have already been ...


Photochemical Hydrogen Doping Induced Embedded Two-Dimensional Metallic Channel Formation in InGaZnO at Room Temperature

01-Oct-2015 | Myeong-Ho Kim; Young-Ahn Lee; Jinseo Kim; Jucheol Park; Seungbae Ahn; Ki-Joon Jeon; Jeong Won Kim; Duck-Kyun Choi; H ..., ACS Nano, 2015

The photochemical tunability of the charge-transport mechanism in metal-oxide semiconductors is of great interest since it may offer a facile but effective semiconductor-to-metal transition, which results from photochemically modified electronic structures for various oxide-based device ...


Topological Winding Number Change and Broken Inversion Symmetry in a Hofstadter’s Butterfly

01-Oct-2015 | Peng Wang; Bin Cheng; Oleg Martynov; Tengfei Miao; Lei Jing; Takashi Taniguchi; Kenji Watanabe; Vivek Aji; Chun Ning ..., Nano Letters, 2015

Graphene’s quantum Hall features are associated with a π Berry’s phase due to its odd topological pseudospin winding number. In nearly aligned graphene-hexagonal BN heterostructures, the lattice and orientation mismatch produce a superlattice potential, yielding secondary Dirac points in ...


Carbon/Silicon Heterojunction Solar Cells: State of the Art and Prospects

30-Sep-2015 | Xinming Li, Zheng Lv, Hongwei Zhu, Advanced Materials, 2015

In the last few decades, advances and breakthroughs of carbon materials have been witnessed in both scientific fundamentals and potential applications. The combination of carbon materials with traditional silicon semiconductors to fabricate solar cells has been a promising field of carbon ...


Semipolar GaN‐based heterostructures on foreign substrates

30-Sep-2015 | Ferdinand Scholz, Marian Caliebe, Gulnaz Gahramanova, Dominik Heinz, Martin Klein, Robert A. R. Leute, Tobias Meisch ..., physica status solidi (b), 2015

Abstract This paper reviews our recent investigations about semipolar GaN‐based optoelectronic heterostructures grown on foreign substrates. Two basically different approaches are discussed, both making use of epitaxial growth in the polar c‐direction to minimize any crystalline defects. By ...
