This paper reports a possible solution for producing electronics using cleaner and more sustainable processes. The authors, from UNESP (Brazil) and the University of Glasgow (Scotland), demonstrated the effectiveness of an innovative method for manufacturing biodegradable and flexible paper electronic devices. They used a laser to draw conductive paths in kraft paper, causing the carbon atoms on the surface to reorganize into graphene-like structures. The conductive paths were used to produce resistive heaters. The group used the life cycle assessment method to measure the environmental impact of this process, showing a reduction in impact of two orders of magnitude compared to conventional methods.

In this article, conducted at Brazilian institutions (UCS, Unicamp and CETENE) and at North Carolina State University (USA), the authors demonstrate a new way to control friction at the nanoscale. In the system prepared for the experiments, consisting of titanium dioxide nanoparticles in aqueous suspension, they observed that exposure to light reduces friction and that, when the light is turned off, friction increases again. The discovery may be a first step towards developing smart lubricants whose properties can be controlled with an external stimulus during use of the product. In addition, the study paves the way for studying the effects of light on other properties of various suspensions. Access the paper.<\/b><\/a><\/span><\/span><\/span><\/p>\n<\/td>\n<\/tr>\n

Using nanocapsules containing minimal doses of herbicide has proven to be a good strategy for achieving better crop results while reducing environmental impact. This research, conducted at UEL and Unesp, further enhanced this effect. The scientific team developed polymeric nanocapsules containing atrazine (a well-known herbicide) and coated them with chitosan (a natural polymer derived from chitin that is biodegradable, biocompatible, and very abundant on the planet). The coating modified the interaction between the nanocapsules and the surface of the leaves, improving the delivery of atrazine to the plants. As a result, the researchers achieved greater weed control using only half the dose applied with the unencapsulated product.

In this work, a Brazilian scientific team developed a process that uses extract from jambolan leaves (Syzygium cumini) as a binder and encapsulator to synthesize iron-doped tin dioxide nanoparticles. The objective of the work was to optimize the properties of the nanoparticles to use them as photocatalysts in environmental remediation processes; that is, to degrade pollutants present in the environment through light-driven oxidation reactions. With the new process, the scientists were able to improve characteristics of this semiconductor oxide that limit its performance in photocatalysis: they expanded its light absorption capacity and increased its quantum efficiency. The work was carried out through the collaboration of researchers from UNIFAL-MG, IFSC-USP, IFMA, UFSCar, UNESP and CDTN. Access the paper.<\/b><\/a><\/span><\/span><\/span><\/p>\n<\/td>\n<\/tr>\n

Researchers Luiza Amim Mercante (UFBA) and Daniel Souza Correa (Embrapa Instrumenta\u00e7\u00e3o), B-MRS members and chairs of our 2025 event, received the Academic Jabuti Award<\/b><\/a> in the Chemistry and Materials category for a book in Portuguese about electrofiber spinning and nanofibers. In the work, they brought together 19 chapters on various aspects of the electrospinning technique, all written by authors from Brazilian institutions. In its first edition, the Academic Jabuti Award, a new award from the Brazilian Book Chamber dedicated to scientific, technical and professional areas, had almost 2,000 works entered.<\/span><\/span><\/span><\/p>\n<\/td>\n<\/tr>\n
