·First demonstrated in 1987 1 2 magnetic force microscopy MFM is a well established and widely used technique Over the last three decades the method has been extensively used in a vast number of applications where the knowledge of the local distribution of the magnetic properties of thin film materials and their nanostructures is of paramount
·Meteorites are our primary source of information about past magnetic fields in the solar system Common magnetic minerals in extraterrestrial materials are Fe Ni metals Rochette et al 2009 which are abundant in equilibrated ordinary chondrites 2 8 vol % enstatite chondrites 10 vol % and iron meteorites Howard et al 2010 Weisberg et al 2006
Light microscopes let us look at objects as long as a millimetre 10 3 m and as small as micrometres thousands of a millimetre or 2 x 10 7 m whereas the most powerful electron microscopes allow us to see objects as small as an atom about one ten millionth of a millimetre or 1 angstrom or 10 10 m So we can think of the microscopic scale as being from a millimetre
Figure 4 illustrates the crystal as it would appear in the eyepieces of a microscope under crossed polarized illumination In each part of Figure 4 the axis of the microscope polarizer is indicated by a P and is oriented in an East West direction The axis of the microscope analyzer is indicated by an A and is oriented in a North South
·Iron and aluminum in red mud were recovered by a reductive sintering magnetic separation digesting process The raw materials were composed of ordinary Bayer red mud MgO Na2CO3 and C in which MgO and Na2CO3 were used as mineralizing agents and C as a reductive agent Sintering orthogonal experiments showed that % content of iron
·The technique of polarising microscopy extracts information about anisotropic materials by utilising the interference of light rays recombined along the same optical path Polarized light microscopy is likely most well known for its applications in the geological sciences which largely examine minerals in thin rock sections
·Scientists have been working to understand how magnetotactic bacteria MTB can sense magnetic fields hoping to harness this ability for a variety of uses including nanoparticle research and even medical treatments Over the years they have discovered many new details about how and why bacteria carry out magnetotaxis which make this behavior
