Reading Tips
– After half a century of international endeavors, scientists have developed a silicon-based material capable of emitting light. The discovery, chosen as “2020 Breakthrough of the Year” by Physics World magazine, opens possibilities for integrating optoelectronic devices into silicon chips (Nature). Know more.
– Scientists present the first detailed experimental study of the structure of bulk metallic glasses (BMGs) – a new family of materials that are both metallic and amorphous, with great potential for industrial application (Materials Today). Know more.
– New technique for manufacturing heterostructures. Scientists are able to rotate layers of two-dimensional materials to align them in the preferred way and thus control the structural properties (Science Advances). Know more.
– Researchers produce a nanostructure with innovative surface texture, capable of penetrating biofilms (colonies of microbes) and generating a chemical reaction that kills bacteria. Since the nanostructures are magnetic it also facilitates removing biofilm debris (Nano Letters). Know more.
– Franco-Brazilian scientific team develops very flexible elongated structures, using a magnetic field to aggregate iron nanoparticles linked by a polymer. Artificial cilia could be used to direct fluids or carry material into cells (The Journal of Physical Chemistry C). Know more.
Covid-19
– Brazilian research generates a portable, low-cost and highly sensitive system for diagnosing Covid-19, based on a genosensor. Know more.
– Research group and startup from São Paulo develop low-cost rapid test, based on nanoparticles, to detect antibodies against Covid-19. The device could be used to monitor the population’s response to vaccines. Know more. |
