Big discovery for biogenic magnetite.
O ne of the most significant characteristics of the Anthropocene (the present age of geologic time) is the rate at which humans are perturbing the global carbon cycle. The potency of carbon dioxide and methane as greenhouse gases and their effects on Earth’s temperature balance is well established (1), and the myriad of climate and ecological changes and feedbacks in response to this abrupt war...
متن کاملControlled cobalt doping in biogenic magnetite nanoparticles.
Cobalt-doped magnetite (CoxFe3 -xO4) nanoparticles have been produced through the microbial reduction of cobalt-iron oxyhydroxide by the bacterium Geobacter sulfurreducens. The materials produced, as measured by superconducting quantum interference device magnetometry, X-ray magnetic circular dichroism, Mössbauer spectroscopy, etc., show dramatic increases in coercivity with increasing cobalt c...

متن کاملMagnetite in the human body: Biogenic vs. anthropogenic.
Magnetite is an iron-oxide mineral that occurs naturally on Earth. Because it is also an important component of many anthropogenic materials (e.g., coal fly ash) and synthetic products (e.g., black toner powders), magnetite can be released to the environment through human activities (1). In PNAS,Maher et al. (2) describe the abundant presence in the human brain of magnetite nanoparticles, some ...
