  • Analysis of the effectiveness of control measures to mitigate road dust emissions in a regional network
    Transportation Research Part D: Transport and Environment, 2012
    Co-Authors: Dongzi Zhu, Hampden Kuhns, John A. Gillies, Vicken Etyemezian, Scott C. Brown, Alan W. Gertler
    Abstract:

    Abstract The effectiveness of control measures to reduce road dust emissions is analyzed using a year’s data of road dust emissions collected with a mobile sampling platform and a survey of road maintenance practices in the Lake Tahoe Basin of Nevada and California US. Attributes such as sweeping practices, anti-icing, shoulder improvement, pavement condition, trackout, and Abrasive Material from road segments were analyzed with a feature subset selection algorithm. Street sweeping was found to be an effective means of controlling dust emissions from roads. Road dust from dirty tertiary roads served as a continuous source of suspendable Material for adjacent high-speed roads in the winter time. To be most effective, emission control strategies require that not only primary roads, but all roads be swept after snow storms to recover applied Abrasive Material.

  • Surface Chemical Processes in Chemical Mechanical Polishing Relationship Between Silica Material Removal Rate and the Point of Zero Charge of the Abrasive Material
    Journal of The Electrochemical Society, 2002
    Co-Authors: K. Osseo-asare
    Abstract:

    Chemical mechanical polishing (CMP) of a silica substrate Is visualized as a two-step process involving release of substrate-derived species into solution (dissolution), followed by adsorption of these species by Abrasive particles. The adsorption is quantified by treating it as a surface complexation process. Mass action equations are provided for the complex-formation reaction as well as protonation and deprotonation of surface hydroxyls present on the Abrasive particles. By combining these equations with mass balances on surface sites and dissolved species, it is shown that the surface concentration of substrate-derived species (and, therefore, the Material removal rate) goes through a maximum as the point of zero charge (pzc) of the Abrasive particle increases. Further, it is shown that the surface concentration of substrate-derived species (and, therefore, the Material removal rate) is highest for the Abrasive Material whose pzc coincides with the pH of the polishing slurry.
