  "main_findings": "The paper reports synthesis of gamma-FeO magnetic nanoparticles and measures their heating performance under an alternating magnetic field. Reported nanoparticle SAR values range from 22–200 W/g at AMF strengths of 100–500 Oe and frequency of 160 kHz, despite low saturation magnetization (1.5–6.5 emu/g).",

    "No sample size or experimental replication details provided in the abstract.",
