Article Synopsis
- The study evaluated how stable magnetite is under high-temperature, oxidizing conditions, specifically at 120, 150, 180, and 275 °C using experimental setups with titanium autoclaves.
- It was found that at temperatures between 120 and 180 °C, magnetite oxidation mostly produced maghemite and hematite with distinct morphologies, while at 275 °C, the main product shifted to hematite with minimal maghemite and a slower reaction rate.
- The oxidation process was linked to the diffusion of ferrous ions, creating a core/shell structure, and at 275 °C, a dense layer of hematite formed quickly, hindering further oxidation
In Renée C. Fox's 2014 book Doctors Without Borders: Humanitarian Quests, Impossible Dreams of Médecins San Frontières, the author explores the ethos of the medical organization, shedding a candid light on its internal culture and its struggles to define and defend its conception of humanitarian action. Through blogs from field workers, numerous testimonies of staff, and extracts from internal gatherings, Doctors Without Borders reveals a side largely unknown to the public and rarely presented in bibliographies of humanitarianism.
