In this work, a team of researchers from USP, UFSCar and UFPI, together with their collaborators from abroad, compared, for the first time, the effects of conventional sintering and flash sintering on the hydroxyapatite-zirconia composite, a material that can be used, for example, in implants, bone regeneration and dental restoration. The team analyzed the changes that occur in the composite during sintering. The results revealed major differences in the microstructure of the material obtained by the two techniques and demonstrated that flash sintering is promising for generating specific structures without the need for other elements such as catalysts.

Due to their ability to convert mechanical energy into electrical energy and vice versa, piezoelectric materials can be fundamental components of various sensors and other electronic devices. And more. In the form of thin films, they can be part of flexible electronic devices, which are increasingly used. In this review article, researchers from Mackenzie and ITA present a comprehensive and up-to-date look at the potential of piezoelectric thin films for building flexible devices and sensors. One of the focuses of the article is the use of sputtering in the synthesis of these films – a technique whose advances currently allow optimizing the composition, structure and performance of piezoelectric films.

Seeking alternatives to the use of antibiotics in agriculture is important to reduce the presence of these drugs in the environment and to contain the development of antibiotic-resistant bacteria. In this work, researchers from IFSC and IQSC at USP bring a contribution from nanotechnology and biotechnology to alternative methods against bacteria in agriculture. The authors studied a complex formed by silver nanoparticles (known for their antimicrobial effect) and endolysin (a protein capable of recognizing certain bacteria and breaking their cell walls). The research confirmed that the complex of nanoparticles and endolysin is capable of eliminating bacteria present in agriculture more efficiently than each of the components separately.

On March 13, Prof Cid de Araújo (UFPE), a B-MRS member, received an award from the National Council of State Research Foundations (CONFAP) for his contributions to the production of knowledge and the development of Brazilian populations. The scientist won 1st place in the Outstanding Researcher category (Exact Sciences area) at the 3º Prêmio CONFAP de Ciência, Tecnologia & Inovação “Johanna Döbereiner”. For this award, candidates are nominated by the research support foundation of their state. The evaluation committees are designated by CNPq, the federal research agency. In 2021, Prof Cid was distinguished by B-MRS with the Memorial Lecture “Joaquim da Costa Ribeiro”.

Prof. Lucimara Stolz Roman (UFPR), scientific director of B-MRS, was approved in her defense for progression to Full Professor on February 29th by an all-female committee (a fact probably unprecedented in defenses of this type in Physics departments in Brazil) . The panel included pioneers such as the first female Presidents of B-MRS, Mônica Cotta and SBF, Débora Peres Menezes, and the first woman to be Full Professor at the Department of Physics at UFPR, Alice Marlene Grimm.
