Considering that 99% of the world’s population is exposed to air quality exceeding recommended pollution limits, air pollution sensors are extremely relevant. However, their use is still limited, mainly because current devices lack sufficient selectivity to quantify specific pollutants in real-world environments, which contain hundreds of interferences. In a recently published review article, researchers from UNESP (Brazil) and ETH (Switzerland) present a systematic comparison of the performance of various air pollution sensor technologies in relation to current air quality guidelines. The study covers sensors based on materials such as metal oxide heterostructures, MOFs, MXenes, and conductive polymers. The article can help develop more efficient and sustainable sensors, as well as their integration into everyday devices and systems, from wearable electronics to smart homes. Go to the paper.

A scientific team led by researchers from Brazilian universities USP and UNESP has shown which heat treatment generates the best properties in Mar18Ni maraging steel. This alloy presents a rare combination of mechanical strength and toughness and has been used to produce parts with complex geometries through additive manufacturing techniques. After processing, heat treatments are performed to adjust some properties. In this work, the authors systematically analyzed the impact of eight post-processing routes on the microstructure and properties of the alloy. They concluded that aging at 480 °C increases the material’s strength, while treatments at 610–670 °C improve its ductility. Furthermore, the scientists showed that the combination of these routes results in an intermediate behavior, offering a balanced combination of strength and ductility. In addition to researchers from Brazil, authors from the United States (Ohio State University) and Germany (Helmholtz-Zentrum Hereon and Max-Planck-Institut) participated in the work.

An international collaborative project coordinated by researchers at the Brazilian university UFSC has yielded fundamental advances in understanding a phenomenon that makes OLEDs more efficient. In these devices, widely used in cell phone screens and high-quality TVs, organic materials emit light when they receive electricity. When these organic materials exhibit the phenomenon of thermally activated delayed fluorescence (TADF), they are able to convert 100% of the injected energy into light emission, making OLED devices more efficient. Typically, the materials used in OLEDs are organic molecules formed by an electron donor and an electron acceptor part, joined together by conjugation, which can be of the “para” or “meta” type. In this new work, the authors used experimental and theoretical methods to investigate the impact of “para” and “meta” conjugations on the TADF phenomenon. They discovered that the delayed emission properties change drastically with these modifications in the molecule’s structure. Go to the paper.

New research from IFSC-USP shows advances in the development of ceramic nanoparticles that could have a major impact on nanomedicine. In the first study, conducted in collaboration with scientists from Germany, the authors modified calcium phosphate nanoparticles to make them more efficient in the direct application of chemotherapy drugs to cancer cells, reducing the harmful effects of the medication on healthy cells. Go to the paper. In the second study, the authors discovered a way to produce luminous hydroxyapatite nanoparticles, which could be used as “nanolanterns” to observe cells inside the body and thus diagnose diseases, monitor health problems, and perform treatments. The developed nanoparticles are composed mainly of abundant and low-cost elements (calcium, phosphorus, and carbon) and obtained through simple chemical reactions in water at room temperature, with high potential for industrial scaling. Go to the paper.

A study by researchers from UFRN and UFOP, in collaboration with scientists from Tsinghua University (China), demonstrates the high potential of a two-dimensional semiconductor in detecting DNA and other molecules. Combining advanced optical spectroscopy and theoretical modeling, the authors investigated the interaction, in an aqueous environment, of molybdenum disulfide with small molecules derived from DNA. Specifically, the scientists studied how these biomolecules are adsorbed onto the semiconductor at the interface with the liquid – a crucial point for the advancement of new biosensors. They showed that biomolecules can modify the electronic properties of the material through doping processes. The work points to ways to develop biosensors based on two-dimensional materials. Go to the paper.

A scientific team from CNPEM, Unesp, and MackGraphe conducted a detailed study on MOFs – the porous nanostructures whose development was the subject of last year’s Nobel Prize in Chemistry. The authors produced thin films of MOFs, which can be easily integrated into electronic nanodevices. Using experimental and computational tools, they investigated how potentially toxic volatile organic compounds (methanol, ethanol, propanol, and hexane) diffuse in these films at the nanoscale. The study broadens the understanding of diffusion mechanisms in porous nanostructures and contributes to the development of more selective sensors and advanced environmental monitoring technologies.

Using two-dimensional materials, researchers from CNPEM, UFSCar, and Unicamp, along with collaborators from Japan, have developed an innovative electronic memory. Ultra-compact and energy-efficient, the new device has potential for use in miniaturized electronics. To produce the “nanomemory,” the authors combined two interesting 2D materials: graphene was used as a conductor and hexagonal boron nitride as a dielectric. The device can function stably over a wide temperature range, including near absolute zero, which would allow its use in space, for example. Furthermore, it is possible to erase the contents of this memory and reuse it. The work was featured on the cover of ACS Applied Electronic Materials. Go to the paper.

A team of researchers from UFRGS and Lawrence Berkeley National Laboratory (USA) conducted a detailed study on nanoparticles capable of enabling so-called “artificial photosynthesis.” In this reaction, carbon dioxide is directly transformed into compounds of industrial value, using sunlight as an energy source. The use of efficient photocatalysts is essential in the process, but developing them still presents challenges. In this work, the authors revealed what happens during artificial photosynthesis with nanoparticles composed of silver and copper, which have already shown their potential as photocatalysts in previous studies. By conducting meticulous experiments, the scientists discovered that a large rearrangement occurs in the nanoparticles throughout the reaction, positively impacting the performance of the nanoparticles. Go to the paper.

A scientific team from Brazil, along with a collaborator from France, challenged a widely held assumption among computational scientists studying energy transfer. The authors questioned the common practice of using an approximate value for the so-called “orientation factor” in computational modeling of fluorescence resonance energy transfer (FRET). This simplification can lead to inaccuracies in predicting material properties related to energy transport, with a potentially significant impact on some optoelectronic devices. To overcome this limitation, the article presents a novel, multiscale computational approach that allows for the direct calculation of the orientation factor. The article reporting this work was featured in a special collection of the Journal of Materials Chemistry A, which includes papers rated as “hot” by reviewers. Go to the paper.
