On magnetite-bearing pegmatites in SE Sottunga, Åland Islands [PDF]
Bulletin of the Geological Society of Finland, 1969 Magnetite-bearing pegmatites of SE Sottunga, Åland Islands, are described. The pegmatites, which are probably granitization products, have derived their magnetite material from the iron-silicates of the host rocks, especially from the biotite.

Advanced Science, EarlyView.A mitochondrial‐targeted FeCD‐SS31 nanoplatform integrates ROS‐responsive SS31 release with cascade antioxidant Fe3O4/CDs cores to suppress both de novo and existing ROS. By restoring mitochondrial complex integrity and blocking caspase‐1–GSDMD‐N pyroptosis, it reduces neutrophil infiltration and alleviates hepatic ischemia–reperfusion injury, while ...

Micro- to nano-sized solid inclusions in magnetite record skarn reactions [PDF]
European Journal of MineralogyMagnetite is a widespread ore mineral in skarn systems and usually hosts a wide variety of inclusions. Micro- to nano-sized solid inclusions in magnetite are unique tools to track the evolutionary processes of its host mineral and, subsequently, to ...

Journal of Applied Polymer Science, EarlyView.Magnetic biocatalysts can be recovered from high‐viscosity reaction media, such as those used in esterification, via magnetic attraction, thereby streamlining the bioprocess and reducing costs. This work builds on prior studies by providing additional data on how particle morphology influences immobilization parameters and by further exploring ...

Magnetite and Magnetotaxis in Algae
Biophysical Journal, 1986 Magnetotactic algae of the genus Anisonema (Euglenophyceae) have been isolated from a coastal mangrove swamp in northeastern Brazil. The magnetotactic response is based on a permanent magnetic dipole moment per cell approximately 7 10(-10) emu. Each cell contains many magnetite (Fe(3)O(4)) particles organized in chains.
