| 英文摘要 | a friendly environmental method was used to prepare a water-based hematite (alpha-fe(2)o(3)) nanofluid through a simple biomolecule-assisted hydrothermal process. the molar heat capacities of the obtained nanofluids, base fluids, and hematite nanoparticles were measured by a high-precision automatic adiabatic calorimeter over the temperature range of (290 to 335) k, respectively. polynomial equations of the molar heat capacities as a function of temperature were fitted by a least-squares method for the solid and nanofluid samples. smoothed heat capacities and thermodynamic functions of the obtained samples, such as h(t/k) - h(298.15 k) and s(t/k) - s(298.15 k), were calculated on the basis of the fitted polynomials and the relationships of the thermodynamic functions. on the basis of the as-obtained molar heat capacities, the excess heat capacities of the nanofluids were calculated. these excess heat capacities reveal that the stable hematite nanofluids exhibit unique properties compared with the unstable one. |
