  • Catalyzed diesel particulate filter modeling 

    Koltsakis, Grigorios; Haralampous, Onoufrios; Depcik, Christopher; Ragone, J. Colter (De Gruyter, 2013-02)
    An increasing environmental concern for diesel particulate emissions has led to the development of efficient and robust diesel particulate filters (DPF). Although the main function of a DPF is to filter solid particles, ...
  • Evaluation of the constant potential method in simulating electric double-layer capacitors 

    Wang, Zhenxing; Yang, Yang; Olmsted, David L.; Asta, Mark; Laird, Brian Bostian (American Institute of Physics, 2014)
    A major challenge in the molecular simulation of electric double layer capacitors (EDLCs) is the choice of an appropriate model for the electrode. Typically, in such simulations the electrode surface is modeled using a ...
  • Bubble dynamics and size distributions during focused ultrasound insonation 

    Yang, Xinmai; Roy, Ronald A.; Holt, R. Glynn (Acoustical Society of America, 2004)
    The deposition of ultrasonic energy in tissue can cause tissue damage due to local heating. For pressures above a critical threshold, cavitation will occur, inducing a much larger thermal energy deposition in a local region. ...
  • Time domain simulation of nonlinear acoustic beams generated by rectangular pistons with application to harmonic imaging 

    Yang, Xinmai; Cleveland, Robin O. (Acoustical Society of America, 2005)
