Experimental conditions of the heat release test of water colloidal dispersions (1.12 mg mL−1) of modified samples. Temperature increases after 10 minutes of applying an alternating magnetic field (ΔT), specific power absorption (SPA), and intrinsic loss power (ILP). The final temperatures reached are reported in Table 2S.
