Electrostatic-doping-controlled phase separation in electron ...

The reversible metal-to-insulator transition enhanced colossal magnetoresistance ∼ 27 000% for V g = 3.0 V and giant memory effect have been observed which can be attributed to an electronic phase separation scenario manipulated by a tiny doping-level-variation of less than 0.02 electrons per formula unit. In addition the controllable ...

Magnetic separation: its appli ion in mining waste ...

The use of strong magnetic field gradients and high magnetic fields generated by permanent magnets or superconducting coils has found appli ions in many fields such as mining solid state chemistry biochemistry and medical research. Lab scale or industrial implementations involve separation of macro- and

Internalization of ferromagnetic nanowires by different ...

Magnetic separation and alignment of cell-nanowire population. The cell separation set-up was made of two Nd 2 Fe 14 B permanent magnets of 10 mm diameter and 15 mm length in antiparallel configuration at opposite sides of a 10 ml falcon tube for cell suspension. The surface magnetic field of the magnets of 0.6 T was measured by hall sensor ...

Magnetic generator – Infinity SAV

The magnetic field of the coil that has been formed after excitation of the coil will tend to collapse generating a back EMF in the coil windings. The designed software of the generator is able to suppress the parasitic current and transform it into usable electrical energy that can be utilized by the end user.

Closed-loop magnetic separation of nanoparticles on a packed ...

In this work we consider magnetic separation of iron oxide nanoparticles when a nanoparticle suspension diluted ferrofluid passes through a closed-loop filter composed of a packed bed of micro-beads magnetized by an externally applied magnetic field.

Origin of colossal magnetoresistance in LaMnO3 manganite PNAS

Magnetoresistance is the change of resistance in the presence of an external magnetic field. In rare-earth manganite compounds this change is orders of magnitude stronger than usual and it is promising for developing new spintronic and electronic devices. The colossal magnetoresistance CMR effect has been observed only in chemically doped manganite compounds. We report the realization of ...

Low-Field Magnetic Separation of Monodisperse Fe3O4 ...

Magnetic separations at very low magnetic field gradients <100 tesla per meter can now be applied to diverse problems such as point-of-use water purifi ion and the simultaneous separation of complex mixtures. High–surface area and monodisperse magnetite Fe3O4 nanocrystals NCs were shown to respond to low fields in a size-dependent fashion. The particles apparently do not act ...

As a response to environmental stress bacterial cells can enter a physiological state called viable but noncultivable VBNC . In this state bacteria fail to grow on routine bacteriological media. Consequently standard methods of contamination detection based on bacteria cultivation fail. Although they are not growing the cells are still alive and are able to reactivate their metabolism ...
