In an article highlighted by Nano Letters on the cover of its 25th anniversary issue, a team from UFSCar and CNPEM introduced the concept of Mem-Emitter. The term refers to an optical memory based on the synergy between two properties of some materials: the ability to “remember” past activities and the ability to emit light. In this pioneering article, the authors demonstrate the operation of a Mem-Emitter formed by ultrathin heterostructures based on transition metal dichalcogenides. The technology could enable innovative applications in neuromorphic computing, photonic networks, adaptive sensors and optical communication. Go to the paper.

A gas sensor that solves a problem of power grid transformers was developed by a team from CTI Renato Archer, Unicamp, Unesp and the energy company CPFL. Through nanoengineering work, the researchers created a filter to remove contaminants in the sensor, which allowed them to measure the presence of hydrogen gas in mineral oil, in real time and with extremely high sensitivity. The device enables early detection of serious failures in transformers. The work opens up possibilities for developing sensors immersed in oil for industrial processes and critical systems.

A new glow-in-the-dark liquid has been featured on the front cover of Chemistry – A European Journal. It is an organic material with low toxicity and flammability that can be used in OLEDs and other organic electronic devices as a light emitter. This is the first example in the scientific literature of a liquid that exhibits delayed fluorescence in blue and phosphorescence at room temperature in orange. The study was conducted by scientists from UFSC, USP and institutions in France and the United Kingdom. Go to the paper.
