An international study led by researchers from UFRN provides guidelines for evaluating the efficiency of magnetic hyperthermia processes. This phenomenon is being studied as a means to combat tumors by heating diseased tissue within the body, and is also used in fundamental research into magnetic and thermal phenomena at the nanoscale, among other applications. In all these contexts, determining the heating efficiency generated by different nanoparticle systems under various conditions is crucial. Currently, the primary metric for quantifying this efficiency is Specific Loss Power (SLP). At the microscopic level, SLP is assessed using theoretical models of magnetic energy dissipation, whereas at the macroscopic level, the assessment relies on experimental measurements of the heat involved in the process. In this new study, the authors investigated the relationship between these two approaches and concluded that they should not be viewed as competing, but rather as complementary, in the description of magnetic hyperthermia. The study involved researchers from the UFRN Magnetism Group and collaborators from UERN, UFRJ, UFSC, CBPF, the University of Minho (Portugal), the University of Santiago de Chile, and Transilvania University of Brașov (Romania).

Research conducted by institutions in the state of Amazonas offers a contribution to the electronics industry, tailored to the specific context of the Manaus Industrial Pole. The authors evaluated the use of graphene nanosheets to enhance the performance of metal alloys used for soldering microelectronic components. Historically, these materials contained significant amounts of lead—an element toxic to both human health and the environment. However, about two decades ago, the industry began adopting lead-free alloys on a large scale, driven by a European Union directive restricting the use of hazardous substances in electrical and electronic equipment. This shift has generated various developments in order to optimize the performance and durability of these new materials within real production processes. In this study, the authors assessed the impact of adding small amounts of graphene to tin-bismuth solder alloys. They demonstrated that, after undergoing the heating and cooling cycles standard in such manufacturing processes, the resulting material exhibited positive changes in its microstructure and surface characteristics. The project was carried out through a partnership between the State University of Amazonas and the Conecthus Institute. Go to the paper.

Researchers from UFPI, UFRPE, and the University of Seville (Spain) have developed a material capable of efficiently performing two important functions: eliminating pharmaceutical residues from bodies of water and combating bacteria. The authors utilized zinc oxide—a low-cost, durable semiconductor—and modified its properties. To achieve this, they controlled the pH during the material’s synthesis and introduced trace amounts of holmium, a rare-earth metal. This allowed them to precisely tune the semiconductor’s structure and, crucially, its defects. Indeed, some of these defects act as active sites for both the photocatalytic processes responsible for drug degradation and the interactions that combat bacteria. The team tested the material’s performance in degrading metronidazole, a widely used antibiotic and antiprotozoal drug. In these tests, holmium-doped zinc oxide synthesized at pH 12 yielded the best results, eliminating over 84% of the substance. The sample produced at pH 12 also performed best in antibacterial assays, inhibiting the growth of 100% of the bacteria. The study demonstrated that pH control is an effective strategy for enhancing the material’s performance as both a photocatalyst and an antimicrobial agent. Go to the paper.
