“Judicious and educative”
Thirteen years have passed since the first number of Mat. Res. was launched! The effort and strategy used to start from
scratch to finally reach the present level has been an invaluable, rewarding experience to me and the associate editors. Mat. Res.
is now indexed in the main international electronic databases, has a solid financial situation and has thousands of readers and
authors from more than 20 countries. Overall, a total of about 900 articles have been already published (and many others
rejected) involving approximately 2000 reviewers and 5000 authors. And from the number of downloads of Mat. Res. articles at
(www.scielo.br/mr), one can infer that we have reached several thousand readers! These numbers are highly significant. Thank
you for your interest and support, authors, readers and reviewers.
It is now time for changes at Materials Research’s editorial team and policies. Due to his reputation and substantial academic
achievements, the three associate editors and I unanimously indicated Prof. Walter Botta – member of our editorial board
and professor of the Materials Engineering Department of the Federal University of São Carlos - as the new editor-in-chief.
Prof. Botta holds a D.Phil. degree in metallurgy and science of materials from Oxford University, UK, and is internationally
known for his articles and conference talks on amorphous, metastable and nanostructured metallic alloys.
The first suggestions I dare to give him are:
i) To renovate the editorial board;
ii) To raise the threshold level for accepted articles;
iii)To implement strategies to reduce the review time. In this way Mat. Res. will be even more attractive to authors and,
as a bonus, its impact factor is likely to increase. At present the time for publication of articles at Mat. Res. varies from
2 to 12 months (generally after 2-3 rounds) and the time for rejection varies from 1 to 6 months.
iv)To focus and strengthen Materials Research’s motto: “judicious and educative”.
I will continue to contribute to Mat. Res. as a member of the editorial board but, starting October first, I will take a new
position as Editor of Elsevier’s Journal of Non-Crystalline Solids, which deals with my favorite research topic.
This 47th issue of Materials Research contains 21 original articles and about 140 are under review. The rejected /accepted
percentage fluctuates around about 30-40%. At present Materials Research is also published in electronic format at SciELO
(www.scielo.br/mr) and is indexed by the Science Citation Index-Expanded (SCIE), which includes the Web of Science, ISI and
Materials Science Citation Index (MSCI), and Scopus.
I take this opportunity to gratefully acknowledge the three associated editors, Profs. F. Rizzo, J.C. Bressiani and L. A. Pessan,
for their invaluable discussions and suggestions along all these years. Of special value to me was the help of Dr. Bressiani who
kindly volunteered to submit proposals to Brazilian funding agency CNPq during several years; and the most efficient work of
the editorial assistant, Luciana Zanotto.
Associação Brasileira de Metalurgia e Materiais (ABM) has been especially helpful due to its continuous financial support
during 13 years! I should also mention that last year Associação Brasileira de Polímeros (ABPol) started to share the cost of the
editorial assistant’s salary. Associação Brasileira de Cerâmica – ABC, ABPol, and ABM have also helped advertising Materials
Research and managing its subscriptions and financial resources. I am also indebted to the Brazilian funding agency CNPq for
covering the editorial and printing costs of this and several other issues of Mat. Res. Last, but not least, the financial support
from the Department of Materials Engineering, Federal University of São Carlos (DEMa/UFSCar) for mailing expenses; the
Vitreous Materials Laboratory (LaMaV/UFSCar) for fax and telephone expenses is deeply acknowledged.
Good luck, Prof. Botta!
