Anna Bajorek, PhD, MSc, Assoc. Prof.
In the first part of the lecture, the following topics will be discussed: Introduction to physics of nanostructures and nanomaterials
• nanotechnologies and nanomaterials,
• a short history of nanotechnology and nanophysics,
• general classification of nanosystems,
• application of nanomaterials in various industries,
• examples of 1D (nanotubes and nanowires), 2D (thin films and coatings) and 3D (nanoparticles and nanocomposites) nanomaterials.
How to produce nanoobjects - selected synthesis methods
• top-down and bottom-up approaches,
• several preparation methods of thin films and multilayer systems,
• optical lithography.
Selected examples of the quantitative description of nanomaterials
• determining the size distribution by dynamic laser light scattering,
• analysis of crystallites size by X-ray diffraction,
• determining the thickness of thin films by X-ray reflectivity,
• using electron microscopy in the visualization of nanostructures.
Afterwards, we will present the following topics:
• magnetic field, magnetic field vector B,
• earth's magnetic field, Gauss's law of magnetic field, motion of electric charge in magnetic field, Lorentz force,
• the magnetic field around a current-carrying wire, conducting wire frame in a magnetic field, magnetic dipole moment,
• magnetism on the atomic scale, orbital and spin magnetic moment, basic quantities (magnetic moment, magnetization, magnetic susceptibility, magnetic field strength),
• types of magnetism (dia-, para-, ferro-, antiferro-, ferri-, heli-, meta-, mikto- spin glasses),
• methods used for testing magnetic materials,
• examples for the application of magnetic materials.
