One of the most abundant iron-containing minerals on Earth, and also the oldest known magnetic material, is magnetite, Fe3O4. Magnetite has applications in many fields, such as the study of paleomagnetism—magnetism in rocks ...
A Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have already been applied ...
