This perspective article, signed by a team from UNESP and USP, addresses recent advances in the encapsulation of bioherbicides using micro and nanoparticles. Key pieces in sustainable agriculture, bioherbicides are products based on microorganisms and their derivatives, used to inhibit the growth of weeds and, therefore, increase the productivity of crops. Despite their numerous benefits, many bioherbicides are susceptible to degradation by environmental factors, a fact that has encouraged the development of encapsulation techniques with the aim of extending the useful life of these compounds, as well as increasing their effectiveness by controlling the release of active ingredients.

Magnetic structures like skyrmions are essential components to develop the next-generation spintronic devices. In this work, researchers from USP, LNLS and UFPA, together with collaborators from Sweden, investigated the origins of skyrmion formation in a multilayer material. Using a combination of computer simulations and results from various experimental techniques, the authors showed that interfacial atomic intermixing is essential for the formation of skyrmions. The work opens perspectives in the development of materials for spintronics. Access the paper at Nano Letters.

In this article, USP researchers and collaborators report an important step in the development of biomaterials for bone regeneration. Using collagen and carrageenan (a polysaccharide extracted from seaweed), the authors produced structures that mimic the organic part of a natural bone matrix, properly fulfilling the function of promoting bone tissue mineralization. The work shows the potential of using these structures as organic matrices for bone implants and for studies on mineralization. Check out the paper in Biomacromolecules.


Electronic ceramics can be used to produce membranes capable of separating gases through the process of permeation (the penetration of gas molecules through the membrane). In this way, it is possible, for example, to separate carbon dioxide from other compounds in order to reduce the emissions of this greenhouse gas into the atmosphere. In this article, IPEN researchers present a system to assess the efficiency of these ceramic membranes. The system simultaneously evaluates the permeation of the material and its electrical properties. The work was awarded in June this year at the 67th Brazilian Congress of Ceramics.

Graphical Abstract LA

Hydroxyapatite coatings are important on titanium implants because they improve their integration into the body and increase their useful life. Currently, plasma spray technique is the most used technique to coat commercial implants, but the equipment that is used in the process is expensive. In this article, a scientific team from UFRGS and UFN presents a low-cost method that could replace plasma spray. The technique is based on a simple brush painting. The coating obtained by the authors complies with all ISO standards for implant coatings. Access the paper at Ceramics International.


In this work, the authors used defect engineering (the controlled introduction of defects in the structure of a material) to modify the optical and surface properties of zinc oxide (ZnO) – a material of great technological and industrial interest. The team, made up of researchers from UFOP, UNIFAL and USP and collaborators from Spain and Finland, doped zinc oxide with different concentrations and atmospheres of manganese and cobalt (two transition metals) and studied their properties in detail. See the article in Acta Materialia.
