A study on a new transistor, conducted by researchers from Brazil (Unesp and Mackenzie) and Germany, was featured on the cover of Advanced Electronic Materials in June. Using low-cost printing techniques, the authors manufactured an EGVFET transistor based on zinc oxide. The new transistor was studied by the scientific team to elucidate its charge transport mechanisms, that is, how charge carriers move through the materials that compose it. In addition, the authors guarantee that the device is capable of allowing or interrupting the passage of electric current when exposed to ultraviolet light depending on its intensity. The advances open up possibilities for applications in nanoelectronics and optoelectronics. Access the paper.

A large portion of the medications we take are excreted and end up polluting the water, since conventional treatments are unable to remove these substances. Therefore, developing advanced techniques to solve the problem is a major challenge. In this article, a team of Brazilian scientists from UFPI, UFAL and UFPE, together with collaborators from the University of Málaga (Spain), report a new approach to remove tetracycline from water, an antibiotic used to treat various infections and widely present in effluents. The researchers achieved a synergistic effect by combining the adsorption of the pollutant and its degradation through photocatalysis. To do this, they developed a nanocomposite formed by a porous adsorbent clay (sepiolite) and a photocatalyst (cerium-doped titanium dioxide). The material was able to remove 70.45% of tetracycline, thanks to the action, in almost equal parts, of adsorption and photocatalysis. Access the paper.

Methanol is a compound that can be used in many everyday products, but when it volatilizes into the air, it has strong toxic effects that can harm human health. Therefore, its effective, real-time detection is necessary. Recently, a scientific team of researchers from UFPR and collaborators from NEXT Chemical (a Brazilian nanomaterials industry) reported the development of a new gas sensor that presented one of the highest responses ever published in methanol detection. The sensor was produced using a simple, low-cost method that can be used on an industrial scale: slot-die. The technique is similar to a printing technique, in which the ink contains the elements needed to form films of the desired material. In this way, the team obtained films of a nanocomposite formed by a conductive polymer and nanoparticles of an inorganic material (zinc oxide). The material was able to detect methanol at room temperature with high selectivity and can be deposited on both rigid and flexible substrates. Access the paper.
