Materials that exhibit at least two ferroic properties are called Multiferroics, when these ferroic orders are coupled together, we are able to manipulate them in a manner way to create new devices. That is the way we create new technologies to supply the increasing demand for computation power and modern data storage.

Luminescence was always an intriguing phenomenon on which materials emits light (photons in a more scientific word). Persistent luminescence as part of luminescent theory, but more related with the defects in solid state materials, is a great approach to develop new materials to emergency safety signs, biomarkers, solar cells, etc. In a more accurate description, we handle with radiation interacting with the matter.

Coupling ferroelectricity of oxides and magnetism of metals can be a good way to develop new spintronic devices. Considering the interface engineering of different materials, we have to spend our efforts in understanding how the physic coupling occur between electric and magnetic forces in nanometric dimensions of solid state materials.

Energy use to be a key point that receives attention in a sustainable modern World. One of the most important achievements of the society was the innovation in renewable energy uses and the Fuel Cells are the technology that came up with the power of hydrogen energy. Electrochemically, hydrogen produces electricity by its redox reactions, and to improve the efficiency of this technology, we develop new oxide materials that act as the positive electrode (cathode) of the continuously fueled SOFC (Solid State Fuel Cell).

Pulsed laser deposition (PLD), sputtering, MBE, ALD, etc are such high powerful techniques to epitaxially stacks atoms onto layers. Heterostructures can be created by spreading atoms on a crystalline oriented substrate from the target. By manipulating film orientation and strain, we have a World of possibilities to manipulate its physical properties.
