Sagdeev pseudo potential method which takes into account the full nonlinearity of plasma equations is used here to study solitary wave solutionenCharged dustDust-acoustic solitary wavesDusty plasmasNonthermalNonthermal plasmaPlasma equationsPseudopotentialsSolitary structuresSolitary wave solutionOther
