Welcome!

A. G. Macedo

is currently Professor at the Physics Department of UTFPR-Brazil. In this page you can find informations about publications, research projects and news. Our research interests are currently focused on the sustainable design and development of organic photovoltaics and/or energy harvesting devices assembled from new copolymers and electron donator/acceptor molecules, as well as optical and electrical properties of these materials. The researcher keeps her great interest in lanthanides, the use of atomic force microscopy to probe effects of solvents or thermal annealing in polymeric thin films and new techniques to process polymer thin films in large areas, such as roll-to-roll method.

You can contact me anytime to explore possibilities for collaborations and opportunities !

The video above shows luminescent Tb3+ complexes with high emission quantum yield produced at the Chemistry Department-UFPR at the researchgroup coordinated by Prof. Jaisa Soares. The optical features have been characterized at the Phantom-g Research Group (UA) coordinated by Prof. Luis Dias Carlos and Prof. Rute Ferreira.

The video above shows a flexible polymer based electrochromic device produced at the NANOTEC-NEO. The curve shows the variation of color along the time upon variable applied voltage.

Our contribution in this pandemic time: A disposable and non-contact paper breathalyzer based on small conjugated molecules/carbon nanotubes electrodes. This work resulted from a collaboration between UTFPR and FIOCRUZ-Curitiba. These devices can be used by officers to detect and quantify alcohol content in drivers. This work was published in PHYSICA STATUS SOLIDI A-APPLICATIONS AND MATERIALS SCIENCE- 2022. Congratulations Sara

January, 2021.

New paper published: In this work, high efficiency and photo-stable Tb3+ complexes were reported. Moreover, a theoretical modelling showed the energy transfer rates along the singlet and triplet states from ligand to Tb3+pathways.

The event "Parents in Science"occurred between 10-11/05/18 at PUC-RS in Porto Alegre. Prof. Andreia attended this event and support the ideas discussed during these 2 days. The maternity has effect on the researchers carrier's and this must be take in count during the evaluation of projects. The link about this initiative can be found below:
