Researchers from CNPEM, in partnership with UFABC, have developed a sustainable material that can be used to package delicate electronic components, such as chips and transistors, protecting them from damage caused by electrostatic discharges. The new material (a cryogel) also hinders the spread of flames and was developed using cellulose and carbon black – materials that can be prepared from agro-industrial waste. The invention, which can replace current antistatic packaging based on petroleum-derived plastics, has been the subject of a patent application. The article reporting the study was featured on the cover of Advanced Sustainable Systems. Go to the paper.

An article featured on ACS Nano´s cover presents an overview of the development and application of oncology nanovaccines. The review was entirely produced by researchers from IFSC-USP. These vaccines are based on nanoparticles that transport tumor antigens and immunological adjuvants directly to the body’s defense cells to teach the immune system to recognize tumor cells and activate a long-lasting response against cancer. Nanoparticles can be designed to fulfill several functions in this process, from protecting the vaccine components and releasing them in a controlled manner, to modulating the desired immune response in order to respond precisely to the type of cancer, stage of the disease and patient profile.

Researchers from Unesp, UFABC and CNPEM have developed a nanomaterial with increased capacity for detecting ethyl acetate (a volatile compound naturally produced by bacteria and fungi, the detection of which is important, for example, to ensure the quality of some foods). The new sensor is made up of nanorods of indium oxide, a semiconductor characterized by its strong interaction with gaseous molecules. To boost the sensor, the scientific team developed a method that additions two phases of indium oxide: the cubic and the rhombohedral one. The combination of the phases generated a synergistic effect, in which the defects in the material increased its reactivity towards ethyl acetate, improving the performance of the device. The article was featured on the cover of ACS Applied Nano Materials. Go to the paper.

Researchers from institutions in Minas Gerais and São Paulo have teamed up to understand phenomena that impair the performance of solar cells and LEDs based on mixed halide perovskites. These materials are low-cost and highly efficient at converting sunlight into electricity. However, they are not able to maintain their properties over time. In this new research, the scientific team used a combination of experimental and computational techniques to study films formed by mixed halide perovskite nanocrystals. The authors were able to understand in detail the migration of halides that occurs in these materials, causing changes in their structure and instabilities in their performance. Go to the paper.

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. Go to the paper.

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.

A team of researchers from Brazilian institutions UFMG, UEMG, CEFET-MG and UFV produced a highly porous carbon material and applied it to the cathode of a lithium-sulfur battery, a promising technology for electric vehicles that stands out for being more sustainable than the lithium-ion technology that currently predominates. The new material was able to store sulfur atoms in its nanometric pores and to improve the cathode’s performance with its good electrical conductivity. Furthermore, because it is produced with tannin and environmentally friendly processes, it maintains the battery’s sustainability standard. Go to the paper.

Researchers from Brazilian institutions CNPEM and UNESP have taken advantage of the properties of synthetic melanin to develop more efficient and sustainable neuromorphic devices, which are those that mimic the functioning of our brain. The authors mixed synthetic melanin, which is biodegradable and processable in environmentally friendly solvents, with a conductive polymer that is normally used in these devices. With this material, they assembled organic electrochemical transistors capable of emulating neural synapses. Go to the paper.

In another study on sustainable neuromorphic devices, a scientific team from UNESP (Brazil) and UNINOVA (Portugal) developed a transistor using a wood sheet, a printed carbon electrode, zinc oxide nanoparticles and a honey electrolyte. The low-cost device performed well in emulating brain synapses. The study was featured on the front cover of the journal Advanced Intelligent Systems. Go to the paper.

Scientists from PUC-Rio, UFMG and CBPF, in collaboration with a researcher from ITS SASA (Serbia), have unraveled the relationship between structural defects and optoelectronic properties in semiconductor nanoparticles that are promising for use in batteries and catalysts. The authors studied “F-type color centers”, defects in the crystal structure that alter the optical properties of materials, often leading to distinct colors. The authors demonstrated how the heat treatment conditions of the material influence the quantity and type of the “F-type color centers” formed. Go to the paper.

A team from UFPR, UnB and UFRJ has conducted a theoretical study that could help improve the efficiency of organic solar cells and LEDs. The authors studied fundamental phenomena that occur in “non-fullerene acceptors” – carbon-based semiconductor molecules that are used to accept and transport electrons in organic optoelectronic devices. In 10 different molecules, the team investigated “intersystem crossing”, which occurs when a molecule changes from one type of spin state to another, affecting the performance of the devices.
