The surface interactions of a near neutral carbon nanoparticle tracer

Abstract A new class of nearly charge neutral carbon cored nanoparticle tracers are remarkably non interactive with solid surfaces and could provide a valuable baseline for diverse hydrological and environmental studies of subsurface flow and particle transport We investigate the causes of inertness by studying the interactions with calcite of a nanoparticle of this class synthesized from
