Diodes are broadly used digital devices that act as one-way switches for present. A well known instance is the LED (light-emitting diode), however there’s a particular class of diodes designed to make use of the phenomenon often known as “quantum tunneling”. Called resonant-tunneling diodes (RTDs), they’re among the many quickest semiconductor devices and are utilized in numerous sensible purposes, akin to high-frequency oscillators within the terahertz band, wave [...]

A group of researchers led by Brazilians has used an innovative model to map gaps in the Amazon rainforest and identify factors that contribute to tree mortality. Water stress, soil fertility, and anthropic forest degradation have the most influence on gap dynamics in the world’s largest and most biodiverse tropical rainforest, according to an article on the study published in Scientific Reports. Forest gaps are most frequent in the areas with the highest levels of soil fertility, [...]

In Brazil, researchers affiliated with the Center for Nuclear Energy in Agriculture (CENA) and the Luiz de Queiroz College of Agriculture (ESALQ), each half of the University of São Paulo (USP), have developed a technique based on artificial intelligence to automate and streamline seed high quality analysis, a course of required by regulation and presently executed manually by analysts accredited with the Ministry of Agriculture. The group used light-based expertise like that deployed [...]

A Brazilian study published (http://www.nature.com/articles/s41467-020-20217-w) in Nature Communications shows that human activities have directly or indirectly caused biodiversity and biomass losses in over 80% of the remaining Atlantic Rainforest fragments. According to the authors, in terms of carbon storage, the biomass erosion corresponds to the destruction of 70,000 square kilometers (km²) of forest – almost 10 million soccer pitches – or USD 2.3 billion-USD 2.6 billion [...]

Researchers at the University of Campinas’s Chemistry Institute (IQ-UNICAMP) in the state of São Paulo, Brazil, have developed a template-free technique to fabricate cilia of different sizes that mimic biological functions and have multiple applications, from directing fluids in microchannels to loading material into a cell, for example. The highly flexible cilia are based on polymer-coated iron oxide nanoparticles, and their motion can be controlled by a magnet. In nature, cilia [...]

Incubated on the University of Campinas (UNICAMP) within the state of São Paulo, Brazil, and supported by São Paulo Research Foundation- FAPESP’s Innovative Research in Small Business Program (PIPE), BIOinFOOD is a startup that’s growing a fast COVID-19 diagnostic test based mostly on a patent software filed by college students at UNICAMP’s Genomics and Bioenergy Laboratory. The test is predicated on a biosensor consisting of a genetically modified [...]
