  • Methods of using carbon nanotubes as filter media to remove aqueous heavy metals 

    Tian, Yuan; Gao, Bin; Morales, Veronica L.; Wu, Lei; Wang, Yu; Munoz-Carpena, Rafael; Cao, Can; Huang, Qingguo; Yang, Liuyan (Elsevier, 2012-11)
    Although carbon nanotubes (CNTs) are well known to have a strong affinity to various heavy metals in aqueous solution, little research has been dedicated to exploit their use in fixed-bed water treatment systems (e.g., ...
  • Quantification of colloid retention and release by straining and energy minima in variably saturated porous media 

    Sang, Wenjing; Morales, Veronica L.; Zhang, Wei; Stoof, Cathelijne R.; Gao, Bin; Schatz, Anna Lottie; Zhang, Yalei; Steenhuis, Tammo S. (American Chemical Society, 2013-08-06)
    The prediction of colloid transport in unsaturated porous media in the presence of large energy barrier is hampered by scant information of the proportional retention by straining and attractive interactions at surface ...
  • Removal of sulfamethoxazole and sulfapyridine by carbon nanotubes in fixed-bed columns 

    Tian, Yuan; Gao, Bin; Morales, Veronica L.; Chen, Hao; Wang, Yu; Li, Hui (Elsevier, 2013-03)
    Sulfamethoxazole (SMX) and sulfapyridine (SPY), two representative sulfonamide antibiotics, have gained increasing attention because of the ecological risks these substances pose to plants, animals, and humans. This work ...
  • Reverse engineering of biochar 

    Morales, Veronica L.; Perez-Reche, Francisco J.; Hapca, Simona M.; Hanley, Kelly L.; Lehmann, Johannes; Zhang, Wei (Elsevier, 2015-02-18)
    This study underpins quantitative relationships that account for the combined effects that starting biomass and peak pyrolysis temperature have on physico-chemical properties of biochar. Meta-data was assembled from published ...
  • Surfactant-mediated control of colloid pattern assembly and attachment strength in evaporating droplets 

    Morales, Veronica L.; Parlange, Jean-Yves; Wu, Mingming; Perez-Reche, Francisco J.; Zhang, Wei; Sang, Wenjing; Steenhuis, Tammo S. (American Chemical Society, 2013)
    This study demonstrates that the pattern assembly and attachment strength of colloids in an evaporating sessile droplet resting on a smooth substrate can be controlled by adding nonionic solutes (surfactant) to the solution. ...
  • Transport and fate of microbial pathogens in agricultural settings 

    Bradford, Scott A.; Morales, Veronica L.; Zhang, Wei; Harvey, Ronald W.; Packman, Aaron I.; Mohanram, Arvind; Welty, Claire (Taylor and Francis, 2013)
    An understanding of the transport and survival of microbial pathogens (pathogens hereafter) in agricultural settings is needed to assess the risk of pathogen contamination to water and food resources, and to develop control ...
  • Transport of titanium dioxide nanoparticles in saturated porous media under various solution chemistry conditions 

    Wang, Yu; Gao, Bin; Morales, Veronica L.; Tian, Yuan; Wu, Lei; Gao, Jie; Bai, Wei; Yang, Liuyan (Springer Verlag, 2012)
    Because of its wide applications, nanosized titanium dioxide may become a potential environmental risk to soil and groundwater system. It is therefore important to improve current understanding of the environmental fate ...
