Query: The effect of particle gas composition and boundary conditions on
  triboplasma generation: a computational study using the particle-in-cell
  method   Two dimensional particle in cell simulations of free charge creation by
collisional ionization of C12 and C60 molecules immersed in plasma for the
parameters of relevance to plasma gasification are presented. Our main findings
are that (i) in uniform plasmas with smooth walls two optimal values which
emerge for free electron production by collisional ionization (i.e. a most
efficient discharge condition creation) are $C60:C12$ fractions of $10:90$ and
$80:20$, (ii) in plasmas with rough walls, modelled by comb-like electric field
at the boundary, the case of tangential electric field creates significant
charge localization in C12+ and C60+ species, again creating most favorable
discharge condition for tribo-electrically generated plasma. The numerical
simulation results are discussed with reference to recent triboelectric plasma
experiments and are corroborated by suitable analytical models.
