We interviewed Gleison Adriano da Silva, one of the winners of the 13th edition of the Special Award in Scientific and Technological Initiation (undergraduate research) of the Brazilian National Council for Scientific and Technological Development (CNPq). The young man, who in November graduated in Physics from the Federal University of Amazonas (UFAM), won the scientific initiation research award in the area of Exact Sciences, Earth and Engineering for his work on structural, thermal and optical characterization of semiconductor systems. The CNPq award highlighted six papers (the best in scientific initiation research and the best in technological initiation research in each area of knowledge) out of 467 works submitted, sent by 167 education and research institutions in Brazil.

The work that earned Gleison the award was developed over three scientific initiation projects that he developed within the Materials Group of the Physics Department of UFAM, under the guidance of Professor Sérgio Michielon de Souza, with funding from the Amazonas Research Foundation (FAPEAM) and CNPq. In these projects, nanostructured semiconductor materials were synthesized by a simple and low cost process. The materials were analyzed using X-ray diffraction, differential scanning calorimetry, micro-Raman spectroscopy, and photoacoustic absorption techniques, and showed good potential to be used as thermoelectric materials in the direct conversion of heat into electricity.

Gleison received a scientific initiation grant (first from FAPEAM and later from CNPq) shortly after beginning the Physics course at UFAM in 2011. His advisor, Sérgio Michielon de Souza, was a new professor at this institution that year and was putting together the Materials Laboratory at the Physics Department, a process in which Gleison actively participated. The first work phase was dedicated to the manufacture and study of Cd-Se system, and its results were published [] in September 2014 in the Journal of Molecular Structure (Elsevier), while he worked on the second work phase, focused on the Ni-Sb system. Also in September 2014, Gleison presented the partial results of the second phase of this work at the XIII SBPMat Meeting held in João Pessoa (PB). His poster received the Bernhard Gross award for the best presentation of the symposium S, dedicated to posters on advanced materials. In May 2015, the final results of the research on the Ni-Sb system were published [] in the International Journal of Materials Research (publisher Carl Hanser Verlag GmbH & Co.). In September 2015, Gleison presented the third work phase, dedicated to the Sn-Se system, at the XIV SBPMat Meeting in Rio de Janeiro (RJ).

Finally, in July 2016, Gleison had the honor to receive the Scientific and Technological Initiation Outstanding Award, in Porto Seguro (BA), during the 68th Annual Meeting of the Society for the Advancement of Science (SBPC). It was the third time he was indicated by the Dean of Research and Post Graduation program of UFAM to compete for the CNPq award, and this time he won the award, with the final research results on the Ni-Sb system and the partial research results on the Sn-Se system. Three months later, Gleison defended his completion course work (TCC), from the studies of Ni-Sb and Sn-Se systems, and obtained a bachelor’s degree in Physics from UFAM.

SBPMat newsletter: – Where were you born? Where did you live until starting university at UFAM?

Gleison Adriano da Silva: – I am originally from Central Brazil, Brasilia (DF), and it all started in 2008 when I applied to be a missionary/community worker of the Roraima Diocese in the North of Brazil, under the command of former titular bishop Dom Roque Paloscci, to work in communities in the lower Rio Branco up to its mouth in Rio Negro.

In 2009, I successfully passed the ENEM exam in Forest Engineering at UFAM, campus Manaus (AM). Without financial assistance, I lived in a hostel in Manaus (AM), however, after the selection process in the Secretary of Community Affairs, moved to the University’s Student Housing, UFAM. In 2011, due to the lack of affinity with the Forest Engineering course, I changed to the Physics course at the Institute of Exact Sciences of UFAM.

SBPMat newsletter: – Could you tell us briefly how your interest in science and research began? Was it at the university, during your childhood, in school?

Gleison Adriano da Silva: – It all happened very fast. Soon after I began the physics course in UFAM, I was invited to do scientific research by Professor Sérgio Michielon de Souza and upon joining the Materials Research Group in the Physics Department of UFAM, I had the opportunity to conduct scientific research focused on the determination of crystal structures, micro/nano-structural evolution and phase transformation in intermetallic materials using computer software and analytical techniques in the Materials Laboratory.

SBPMat newsletter: – In your opinion, what is the main contribution of the winning work? Or, what are the main contributions of the winning works?

Gleison Adriano da Silva: – An interesting observation is that the awarded investigations were coincidentally related to the 2014 and 2015 UNESCO celebratory themes –  International Year of Crystallography and International Year of Light. From this perspective, the main contributions in the award-winning works were related to X-ray diffraction techniques, that is, changes and stability of crystallographic phases of samples of the Ni-Sb and Sn-Se semiconductor system during the solid state synthesis, where strong structural stability of nickel antimonide crystals (NiSb) and remarkable metastability of tin selenide crystals (SnSe) were observed.

A simple work that presents microstructural and thermodynamic characteristics of two new nanostructured materials of scientific and technological interest subjected to non-complex synthesis route and of low cost.

SBPMat newsletter: – What were the guiding criteria to conduct outstanding quality research at the national level? To what factors do you attribute this achievement?

Gleison Adriano da Silva: –There is no Columbus’ egg or success recipe, only hard work. Nothing happens without effort. As an undergraduate with a scientific initiation grant, I was always the first to arrive and the last to leave the lab. The achievement is the recognition of work, however, nothing can be done alone.

SBPMat newsletter: – Please leave a message for our readers who are conducting scientific initiation research work in the Materials area.

Gleison Adriano da Silva: – Believe in your potential and in the potential of your investigations. It is the dream that moves us, but it is not enough to dream, you must chase the dream. I also urge you to consider this as encouragement to disseminate your research results in scientific events in Brazil, especially in the SBPMat Annual Meetings.

SBPMat newsletter: – What are your plans now that you have graduated?

Gleison Adriano da Silva: – After this long process, I will probably look for a Graduate Program at the University of Brasilia (UNB) or at some renowned SP institution.

SBPMat newsletter: – Feel free to make another brief comment.

Gleison Adriano da Silva: – I would like to thank the congratulations letters and praise I received from the Head of the Physics Department of UFAM, Professor Marcílio de Freitas; from the Director-President of FAPEAM, Professor Maria Olívia de Albuquerque Ribeiro Simão; and from Senator Vanessa Grazziotin, Brazil’s National Congress (

I would also like to thank the city of Manaus (AM), the UFAM and all who directly or indirectly contributed to my personal and academic background.
