Abstract

Correct estimation of the heating power of magnetic nanoparticles is important for magnetic hyperthermia treatment. This letter investigates the impact of sample insulation in ac calorimetry. We show that a temperature increase in the insulation can lead to systematic errors when estimating the heating power by the corrected slope method. The errors arise if the temperature of the sample environment is kept fixed at its initial temperature in the data analysis. To correct this, the local temperature difference between the sample and the sample environment should be used.

样品绝缘对交流量热法估算磁性纳米粒子加热功率的影响

正确估计磁性纳米颗粒的加热功率对于磁热疗治疗是重要的。这封信调查了交流量热法中样品绝缘的影响。我们表明，当用修正斜率法估计加热功率时，绝缘层的温度升高会导致系统误差。如果在数据分析中样品环境的温度保持固定在其初始温度，则会出现误差。为了纠正这种情况，应使用样品和样品环境之间的局部温差。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
