Photoluminescent nanoparticles can play a crucial role in diagnostic imaging methods used in medicine due to their ability to emit light inside living organisms and cells. They can also be used in theranostic medicine, which combines diagnosis and treatment in the same procedure. In this recently published article, a group of researchers from IFSC-USP and UFSCar presents new photoluminescent and biocompatible nanoparticles, made from carbonated calcium phosphate and functionalized with citrate. Using simple, low-cost methods, the team was able to optimize the luminescence of these nanoparticles, in addition to increasing their stability. The work highlights the potential of this material for bioimaging and theranostics. Access the paper.

This paper reports an innovative approach to degrading the glyphosate molecule – a herbicide widely used in agriculture, which ends up polluting water and soil. In this proposal, glyphosate powers a fuel cell based on a photoanode that captures sunlight and promotes spontaneous reactions capable of degrading the molecule and, at the same time, generating electricity. The authors of the work, researchers from UFMS and LNNano-CNPEM, carefully developed the photoanode materials in order to increase their efficiency. Access the paper.

In this article, a multidisciplinary team of researchers from Unesp, Unicamp and PUC-Rio presents an new antenna for satellite communication with better performance than conventional ones. The team developed an innovative design based on mathematical models and was able to manufacture it thanks to the use of metal additive manufacturing. The authors made adjustments to the design of the classic helical antenna, invented in the 1940s. By proposing wires with variable diameters throughout the antenna, they managed to bring together the main advantages of thick-wire and thin-wire antennas. Additive manufacturing was essential to enable the precise manufacturing of a device with complex geometry using high-quality steel. Access the paper.

Recently granted to UFRN by the Brazilian National Institute of Industrial Property (INPI), this letter patent protects the invention of a material with high sensitivity to deformation that could be used as a touch sensor. The technology is based on the use of magnetostrictive films, which change their magnetic properties when subjected to some degree of deformation. To maximize the effect, the authors carried out a detailed study to transfer these properties, already well studied in rigid substrates such as glass, to flexible substrates. Using the magnetron sputtering technique, they deposited nanostructures based on cobalt alloys on flexible polymeric substrates. The material obtained allows controlling the level of sensitivity through external magnetic fields and variations in the frequency of electrical current. This possibility may be interesting for technological applications, such as, for example, touch systems on car steering wheels, where sensitivity control must be rigorous to avoid accidents.
