Laboratório de Espectroscopia Não-Linear de Interfaces (LENI)

About LENI (PO/IFSC/USP):

The Nonlinear Spectroscopy of Interfaces Lab (LENI, Laboratório de Espectroscopia Não-Linear de Interfaces), is a laboratory within the "Prof. Bernhard Gross" Polymers Group (PO/IFSC), under the responsability of Prof. Dr. Paulo Barbeitas Miranda. It has a nonlinear SFG and SHG optical setups that can be coupled with Langmuir trough, to investigate air-liquid interfaces (particularly useful for bioinspired applications). Besides, Air-solid, liquid-solid, liquid-liquid, and solid-solid interfaces can also be investigated. 

"Prof. Bernhard Gross" Polymers Group (PO/IFSC)

About "Prof. Bernhard Gross" Polymers Group:

The Group of Polymers “Prof. Bernhard Gross “was created in the middle of the 70’s, at the initiative of Profs. Guilherme F. Leal Ferreira and Milton S. Campos, from the visits of Prof. Bernhard Gross to São Carlos. In their first works, members of the Group acted in the study of electrical properties of insulating polymers, their theoretical, experimental aspects and applications of the electrets.

From the end of the 1980s, the Group’s areas of activity were significantly extended with the study of new materials such as ferroelectric polymers, electron-conducting polymers, ultra-thin films obtained by Langmuir-Blodgett and self-assembly techniques, Polymers of interest for non-linear optics and luminescent polymers. With these new lines of research, a scientific interaction with several international groups emerged, intense collaboration with chemists to master the techniques of synthesis and processing and characterization of new materials.

The Polymer Group has 5 researchers, collaborating researchers, postdoctoral researchers and visitors. It has an experimental infrastructure such as a chemistry laboratory, clean rooms, fine film preparation techniques, LB film preparation tanks, electrical and electro-optical equipment, and polymer characterization. He also has a technician in organic chemistry (with doctor level) and three specialized technicians.
