Scientists from PUC-Rio, UFMG and CBPF, in collaboration with a researcher from ITS SASA (Serbia), have unraveled the relationship between structural defects and optoelectronic properties in semiconductor nanoparticles that are promising for use in batteries and catalysts. The authors studied “F-type color centers”, defects in the crystal structure that alter the optical properties of materials, often leading to distinct colors. The authors demonstrated how the heat treatment conditions of the material influence the quantity and type of the “F-type color centers” formed. Go to the paper.

A team from UFPR, UnB and UFRJ has conducted a theoretical study that could help improve the efficiency of organic solar cells and LEDs. The authors studied fundamental phenomena that occur in “non-fullerene acceptors” – carbon-based semiconductor molecules that are used to accept and transport electrons in organic optoelectronic devices. In 10 different molecules, the team investigated “intersystem crossing”, which occurs when a molecule changes from one type of spin state to another, affecting the performance of the devices.

A team of researchers from Brazilian institutions USP, CTI Renato Archer, UNIFEI and UFSCar has just presented an innovative strategy for producing ceramic structures that are used as scaffolds for bone tissue regeneration. The approach, which combines additive manufacturing and rapid sintering techniques, allows for the high-quality production of structures with complex geometries in short times and with low energy consumption. The strategy could also be used with other ceramic materials, opening doors to a wide range of applications. Go to the paper.

Researchers from Unicamp and CNPEM studied the performance and durability of electrolyte-gated transistors, devices that connect ionic and electronic phenomena and are ideal for use in bioelectronic technologies, such as biosensors or brain-machine interfaces. The authors produced a transistor with reduced graphene oxide in the active layer and analyzed its response to the application of electrical pulses of different durations and voltages. The results should help develop more robust and efficient bioelectronic devices. Go to the paper.

End of year message

The year 2024 demonstrated the strength of the Brazilian materials research community, with the B-MRS Meeting held in Santos attracting nearly 1,800 participants from areas ranging from basic to technological sciences. Around 60% of these were undergraduate, master’s or doctoral students, illustrating the importance of the event in bringing together these young scientists and providing opportunities for the dissemination of their research and the establishment of scientific collaborations. Technical lectures and round tables addressed gender issues and encouraged scientific dissemination and entrepreneurship.

B-MRS has contributed to the dissemination of opportunities for researchers and students. The dissemination of papers by the community has illustrated the relevance of the scientific work produced by members of the Society.

In 2025, we hope to strengthen and expand B-MRS University Chapters (UCs), which have weakened during and after the Pandemic. We understand that the UCs represent the future of the Society and can contribute greatly to the training of new generations of scientists in Materials, promoting the inclusion of new students and the scientific dissemination of the area. Professors and students interested in opening a UC at their institution should contact Professor Lucimara Roman (romanlucimara@gmail.com).

The organization of the B-MRS Meeting 2025 is in full swing. The event will be held from September 28 to October 2 in Salvador/BA. There will be 22 scientific symposia in the most varied areas of activity in Materials, in addition to internationally renowned speakers. Do not miss the opportunity to participate in this event.

We wish everyone an excellent 2025, full of personal and professional achievements. May we all contribute to the scientific development of Brazil, to the training of new generations of scientists and to stimulate entrepreneurship.

A team from UFPA, USP and Instituto Tecnológico Vale used nanostructured additive manufacturing to produce a pressure sensor that could be used, for example, in subway door actuators. The researchers developed a nanocomposite based on carbon nanotubes in a polymer matrix and produced the sensor using additive manufacturing, in order to induce changes in electrical resistance in response to pressure received from the environment. Go to the paper.

Zinc anode batteries are promising candidates for commercialization, as they can combine low cost, sustainability, safety and efficiency. The problem is that a suitable material to act as a cathode in these batteries has not yet been found. In this study, a team of scientists from UFPA, UFS, USP and Swedish institutions investigated three compounds, also based on zinc, to evaluate their potential as cathodes for zinc-ion batteries. Using theoretical calculations, the authors examined the structure, electronic properties and electrolytic performance of these compounds, and listed the advantages and limitations of each one for the desired application. Go to the paper.

Traditionally, the main thermodynamic factors behind sintering are considered to be the curvature of the “neck” that forms between two particles (responsible for eliminating porosity) and the difference in grain size (responsible for grain growth). Now, a theoretical study conducted by a Poli-USP researcher brings a new perspective to understanding how sintering occurs. The work highlights that the difference in energy between the surface and grain boundaries is the most important factor in eliminating porosity during sintering. Go to the paper.

In the semi-arid region of the state of Paraiba, a scientific team from UFPB and UFRN found a raw material to produce nanoparticles that can be used to obtain hydrogen. The researchers used extracts from the plant Ipomoea asarifolia, popularly known as “salsa brava”, as stabilizing agents in the synthesis of nickel nanoparticles. In the experiments, the material demonstrated excellent performance as a catalyst for the electrochemical reactions that split the water molecule, generating hydrogen. Go to the paper.

A scientific team from the State University of Maringá has developed a new material that helps regenerate skin and bones. Composed of the polymer PMMA, gelatin and zinc-modified hydroxyapatite, the composite was used to manufacture small scaffolds that are essential for promoting the natural repair of damaged tissues. In addition to stimulating rapid cell proliferation, the new scaffolds showed antibacterial action in in vitro tests. In the future, the material could help patients recover more quickly and safely from conditions such as chronic skin wounds and bone fractures. Go to the paper.

A book in Portuguese about the physical properties of materials was recently released by the publisher Blucher. Undergraduate and graduate students of courses on materials and related subjects will benefit directly from reading this work. Written by Prof. Sérgio Camargo (UFRJ), a B-MRS member, the book shows the relationship between the properties of various materials and concepts of Physics, and provides examples of applications in everyday technologies. The author, who holds degrees in Physics from PUC-Rio in his undergraduate, master’s and PhD, has extensive experience in the area of ​​materials engineering. Learn more.
