    Abstract: Provided are an anode active material for secondary battery which includes porous iron oxide nanoparticles, a manufacturing method thereof, and a secondary battery including the same. The anode active material for secondary battery of the present disclosure minimizes a volume change of iron oxide caused by intercalation and deintercalation of lithium even during consecutive charges and discharges and thus can improve the capacity and lifespan characteristics of a secondary battery employing the anode active material. Further, the manufacturing method of an anode active material for secondary battery makes it possible to manufacture an anode active material for secondary battery including iron oxide nanoparticles in an environmentally friendly and simple manner and thus makes it possible to mass-produce the anode active material.

    Abstract: Disclosed is a temperature distribution measuring device for measuring the temperature distribution or the heat generation distribution in a sample. An embodiment collects a reflection signal the reflectivity of which changes on the basis of a bias signal applied to a sample, detects a signal of interest, which has been reflected from a region of interest in the sample, from the reflected signal, converts the signal of interest to a frequency range signal, calculates the relative amount of change in reflectivity of the sample by using a direct current component extracted on the basis of filtering of the frequency range signal and a frequency component of the bias signal, and acquires a thermal image of the sample on the basis of the relative amount of change in reflectivity.
