  • Sign-changeable spin-Filter Efficiency in linear carbon atomic chain
    Physica E: Low-dimensional Systems and Nanostructures, 2013
    Co-Authors: Jiaxin Zheng, Qihang Liu, Zhengxiang Gao, Lu Wang, Qiye Zheng, Ruge Quhe, Jun-jie Shi
    Abstract:

    Abstract It is well known that there is spin-Filter Efficiency (SFE) of a linear carbon atomic chain. In this article, we examine the quantum transport calculations of a linear carbon atomic chain connected to two half-planar graphene electrodes by using the first-principle method and reveal for the first time that sign of the SFE of such carbon atomic chain is changeable with the bias. This makes the carbon atomic chains attractive to potential application of spintronics.

  • Giant magnetoresistance in silicene nanoribbons
    Nanoscale, 2012
    Co-Authors: Guangfu Luo, Qihang Liu, Jiaxin Zheng, Zhimeng Zhang, Shigeru Nagase, Zhengxiang Gao
    Abstract:

    By performing first-principle quantum transport calculations, we predict a giant magnetoresistance in zigzag silicene nanoribbons (ZSiNRs) connecting two semi-infinite silicene electrodes through switch of the edge spin direction of ZSiNRs. Spin-Filter Efficiency of both the antiferromagnetic and ferromagnetic ZSiNRs is sign-changeable with the bias voltage. Therefore, potential application of silicene in spintronics devices is suggested.

  • Sign-changeable spin-Filter Efficiency and giant magnetoresistance in seamless graphene nanoribbon junctions
    Computational Materials Science, 2011
    Co-Authors: Rui Qin, Guangfu Luo, Qihang Liu, Jiaxin Zheng, Xin Yan
    Abstract:

    Abstract Sign-changeable spin-Filter Efficiency is predicted in both the ferromagnetic and antiferromagnetic configurations of a zigzag graphene nanoribbon bridging two half-planar graphene electrodes from ab initio quantum transport calculations. By changing edge spin-polarization configuration, we obtain giant room-temperature magnetoresistance, which is one order of magnitude larger than the maximum experimental results.

  • Removal of phenol and chlorine from wastewater using steam activated biomass soot and tire carbon black.
    Journal of hazardous materials, 2018
    Co-Authors: Anna Trubetskaya, Jens Kling, Olov Ershag, Thomas M. Attard, Elisabeth Schröder
    Abstract:

    This study aims to demonstrate a novel method for removing toxic chemicals using soot produced from wood and herbaceous biomass pyrolyzed in a drop tube reactor and tire pyrolytic carbon black. The influence of ash content, nanostructure, particle size, and porosity on the Filter Efficiency of steam activated carbon materials was studied. It has been shown for the first time that steam activated soot and carbon black can remove phenol and chloride with Filter efficiencies as high as 95%. The correlation of Filter Efficiency to material properties showed that the presence of alkali and steam activation time were the key parameters affecting Filter efficiencies. This study shows that steam activated biomass soot and tire carbon black are promising alternatives for the cleaning of wastewater.
