Magnetite tattoos

Lasers in Surgery and Medicine, 2002
AbstractBackground and ObjectivesTattoo removal is a significant problem. The extraction of magnetite (Fe3O4) ink tattoos by a magnetic field was investigated, with and without Q‐switched laser treatment.Study Design/Materials and MethodsMagnetite particles (1.4 μm) were used to make mature, black skin tattoos on hairless albino rats. A Q‐switched ruby

Magnetite Biomineralization in Bacteria

2011
Magnetotactic bacteria are able to biomineralize magnetic crystals in intracellular organelles, so-called "magnetosomes." These particles exhibit species- and strain-specific size and morphology. They are of great interest for biomimetic nanotechnological and biotechnological research due to their fine-tuned magnetic properties and because they ...

Magnetite Pneumoconiosis

Journal of Occupational and Environmental Medicine, 1978
A subject is described who was exposed to fine particles of magnetite (Fe3O4). His chest radiograph demonstrated the presence of multiple small rounded opacities; however, his lung function remained unaffected.

Characterization of magnetite nanoparticles

2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2014
This paper deals with the chemical preparation and magnetic characterization of nanoparticles of magnetite. A new hydrothermal synthesis of magnetite is adopted to prepare samples with different particle sizes and magnetic measurements are performed in two different laboratories adopting two different measurement methods.

Extracellular Synthesis of Magnetite and Metal-Substituted Magnetite Nanoparticles

Journal of Nanoscience and Nanotechnology, 2006
We have developed a novel microbial process that exploits the ability of Fe(III)-reducing microorganisms to produce copious amounts of extracellular magentites and metal-substituted magnetite nanoparticles. The Fe(III)-reducing bacteria (Theroanaerobacter ethanolicus and Shewanella sp.) have the ability to reduce Fe(III) and various metals in aqueous ...

Magnetostriction and Permeability of Magnetite and Cobalt-Substituted Magnetite

Physical Review, 1955
The principal magnetostriction constants of magnetite were determined over the temperature range from 120\ifmmode^\circ\else\textdegree\fi{}K to 300\ifmmode^\circ\else\textdegree\fi{}K by the strain gauge technique. Since ${\ensuremath{\lambda}}_{111}$ and ${\ensuremath{\lambda}}_{100}$ are different in sign and practically constant over this entire ...

Nitrite Reactivity with Magnetite

Environmental Science & Technology, 2013
Under Fe(3+)-reducing conditions, soil Fe(2+) oxidation has been shown to be coupled with nitrate (NO3(-)) reduction. One possible secondary reaction is the involvement of NO3(-) and nitrite (NO2(-)) with magnetite, a mixed valence Fe(2+)/Fe(3+) mineral found in many natural environments.

Magnetite-based magnetoreception

Current Opinion in Neurobiology, 2001
Orientation, navigation, and homing are critical traits expressed by organisms ranging from bacteria through higher vertebrates. Sensory systems that aid such behavior have provided key selective advantages to these groups over the past 4 billion years, and are highly evolved; magnetoreception is no exception.

Preparation and Properties of Magnetite and Polymer Magnetite Nanoparticles

Langmuir, 1999
A novel approach to prepare magnetic polymeric nanoparticles by synthesis of the magnetite core and polymeric shell in a single inverse microemulsion is reported. Stable magnetic nanoparticles colloid dispersion with narrow size distribution can thus be produced.
