Schematic representation of the equivalent circuit employed to the obtainment of the effective thermal conductance, taking into account the conduction and convection processes contributing to the energy exchange between suspension and environment. Here, we represent \(r_{air,top} =1/\epsilon _{air,top}\) as the thermal resistance of the air at the interface sample/air, \(r_{air,surf} = 1/\epsilon _{air,surf}\) as thermal resistance associated to the convection of the air on the outer surface of the sample holder, and \(r_{sh} = 1/\epsilon _{sh}\) as thermal resistance of the sample holder.
