    • Photophoresis on polydisperse basalt microparticles under microgravity 

      Kupper, M.; de Beule, C.; Wurm, G.; Matthews, L.; Kimery, J.; Hyde, T.W. (Journal of Aerosol Science, 2014-10)
      Photophoresis is a force which can dominate the motion of illuminated aerosols in low pressure environments of laboratory experiments, planetary atmospheres or protoplanetary disks. In drop tower experiments we quantified ...
    • Photophoretic Force on Aggregate Grains, Monthly Notices of the Royal Astronomical Society 

      Matthews, Lorin; Kimery, J. B.; Wurm, G.; de Beule, C.; Kuepper, M; Hyde, T. W. (Monthly Notices of the Royal Astronomical Society, 2016-01-21)
      The photophoretic force may impact planetary formation by selectively moving solid particles based on their composition and structure. This generates collision velocities between grains of different sizes and sorts the ...
    • Probing the sheath electric field using thermophoresis in dusty plasma 

      Land, Victor; Smith, Bernie; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, 2010-04)
      A self-consistent dusty plasma fluid model has been extended to incorporate all the oble gases as the carrier gas. An analysis of void closure in complex plasma composed of these gases over a wide range of experimental ...
    • Simulation of dust voids in complex plasmas 

      Goedheer, Jan Willem; Land, Victor (IOP Publishing, 2008-11-04)
      In dusty radio-frequency (RF) discharges under micro-gravity conditions often a void is observed, a dust free region in the discharge center. This void is generated by the drag of the positive ions pulled out of the ...
    • Vibrational Modes and Instabilities of a Dust Particle Pair in a Complex Plasma 

      Qiao, Ke; Matthews, Lorin; Hyde, Truell (IEEE Transactions on Plasma Science, 2010-04-10)
      Vibrational modes and instabilities of a dust-particle pair in a terrestrial aboratory complex plasma are investigated by employing an analytical method whereby the plasma wakefield induced by an external electric field ...
