Innovative Method Simplifies, Safeguards Cheap Acetone Production
Publicado em 13 de setembro de 2023
Acetone is an essential chemical industry input and is used in the manufacturing of a wide array of products, such as adhesives, antibiotics, electronic components, solvents and removers, inks and vitamins, among others. Its production is complex and hazardous. To simplify the process and make it safer and cheaper, researchers in Brazil and Germany have developed an innovative method that uses only light and photoactive iron chloride (FeCl3), an inexpensive chemical compound.

SARS-CoV-2 infection can exacerbate production of auto-antibodies relating to auto-immune diseases
Publicado em 12 setembro 2023An article published in NPJ Aging, a Springer Nature journal, reveals that natural production of auto-antibodies increases with age and that infection by SARS-CoV-2 can exacerbate production of auto-antibodies relating to auto-immune diseases, helping to explain why aging increases the chances of developing severe COVID-19. The study also discovered some of the factors that associate the severe form of the disease with blood clotting disorders such as thrombosis. These findings open the [...]News Medical (Austrália) -

Research Reveals Oxide's Role in Specialty Glass Development
Publicado em 06 setembro 2023A study conducted at the Center for Research, Education and Innovation in Vitreous Materials (CeRTEV) in São Carlos, São Paulo state, Brazil, shows for the first time that including niobium oxide (Nb2O5) in silicate glass results in silica network polymerization, which increases bond density and connectivity, enhancing the mechanical and thermal stability of specialty glass. The study was supported by FAPESP and reported in an article published in the journal Acta [...]Mirage News (Austrália) -
Population Dynamics of Saccharomyces cerevisiae in Biorefineries
Publicado em 31 agosto 2023Investigators at the State University of Campinas (UNICAMP) in Brazil collaborated with coworkers at Harvard University in the United States to conduct inventive research on the DNA and population dynamics of Saccharomyces cerevisiae, the yeast used by plants throughout Brazil to generate fuel ethanol from sugarcane, to find routes to more stable, consistent, and predictable fermentation performance. The study’s foundations were metagenomics and whole-genome sequencing (the analysis of [...]AzoCleantech.com (Austrália) -
Amazonian Lowland Rainforest at Risk of Turning Into Dry Savannas Due to Climate Change
Publicado em 30 agosto 2023A portion of Amazonian lowland rainforest – areas critical to absorbing carbon dioxide and buffering climate change – may morph over time into dry, grassy savannas, according to a Rutgers-led study. The report, published in the scientific journal Proceedings of the National Academy of Sciences, described a new understanding of how alternating flooding in the wet season and drought in the dry season, called double-stress, can limit forest establishment and favor short-lived grass [...]AzoCleantech.com (Austrália) -
