The crystal field of a host material has a profound effect on the UC efficiency of lanthanide emitters, as the local crystal symmetry surrounding a lanthanide ion strongly influences its optical properties.
The paper emphasizes the strengths derived from the employment of full-field methods when the strain field of an anisotropic material must be evaluated.
Magnetic flux density B is a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area.
Meissner effect, the expulsion of a magnetic field from the interior of a material that is in the process of becoming a superconductor, that is, losing its resistance to the flow of electrical currents when cooled below a certain temperature, called the transition temperature, usually close to absolute zero.
One of the most urgent problems in the field of a new porous semiconductor material synthesis is the systematic study of the change of the electrical conductivity during the pore formation.
We explored a new approach within the field of hybrid materials, namely, an integration of an electroactive inorganic molecule into a conducting polymer that in turn is intercalated into an extended inorganic oxide.
Hysteresis is the variation of magnetization with applied field and illustrates the ability of a material to retain its magnetization, even after an applied field is removed.
They published their work in one of the most respected journal in the technical field of "material sciences," a multidisciplinary field that integrates chemistry, engineering, and physics.
In the simulations of pure electromagnetic problems, the satisfaction of tangential field continuity across a material interface is sufficient to yield accurate numerical results.
Examine a piece of normal brain under a microscope, and you will see a field of pinkish uniform material punctuated by darker blue islands in a pattern that looks a bit like banana bread.
