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.
