Beneath the Earth's mantle lies the core, which is made up of two parts: the solid inner core and liquid outer core. [ 16 ] [ 17 ] Both have significant quantities of iron . The liquid outer core moves in the presence of the magnetic field and eddies are set up into the same due to the Coriolis effect . [ 18 ]
Magnetic 2D materials can be used as a part of van der Waals heterostructures. They are layered materials consisting of different 2D materials held together by van der Waals forces. One example of such structure is a thin insulating/semiconducting layer between layers of 2D magnetic material, producing a magnetic tunnel junction.
The mission was selected for support by NASA in 2005. System engineering, spacecraft bus design, integration and testing has been performed by Goddard Space Flight Center in Maryland. Instrumentation is being improved, with extensive experience brought in from other projects, such as the IMAGE, Cluster and Cassini missions.
Earth's magnetic field is produced in the outer liquid part of its core due to a dynamo that produce electrical currents there. The ions and electrons of a plasma interacting with the Earth's magnetic field generally follow its magnetic field lines. These represent the force that a north magnetic pole would experience at any given point.
In nuclear fusion power research, the plasma-facing material (or materials) (PFM) is any material used to construct the plasma-facing components (PFC), those components exposed to the plasma within which nuclear fusion occurs, and particularly the material used for the lining the first wall or divertor region of the reactor vessel.
The High-frequency Active Auroral Research Program (HAARP) is a University of Alaska Fairbanks program which researches the ionosphere – the highest, ionized part of Earth's atmosphere. The most prominent instrument at HAARP is the Ionospheric Research Instrument (IRI), a high-power radio frequency transmitter facility operating in the high ...
Her research program centers on the design and processing of new materials that are fit for extreme environments, such as those experienced in outer space or in nuclear reactors. Among the materials her research group works on is a type of steel, called SAM2X5-630, with record-breaking resistance to deformations due to heavy impacts.
