Chiral gold nanoparticles increase vaccine efficacy by more than 25%, study suggests
Publicado em 18 de abril de 2022
Vaccines can be made over 25% more effective by adding left-handed chiral gold nanoparticles as adjuvants, according to a study by an international collaboration in which Brazilian researchers took part. An article reporting the results is published in Nature.
Three research groups collaborated on the study, one affiliated with the University of Michigan in the United States, and another with Jiangnan University in China. The Brazilian group was led by André Farias [...]

Brazil may boost ethanol production without deforestation
Publicado em 04 fevereiro 2019By integrating the cultivation of sugarcane for ethanol with beef cattle breeding on the same land, Brazil could increase food and sustainable fuel production without extra deforestation, a study suggests. Brazil is already the world’s largest sugarcane producer, the largest sugar producer, and the second largest ethanol producer. In 2017, the country produced over 600 million tonnes of sugarcane. The country has also the second biggest cattle herd after the US, with over 200 million heads, [...]ver notícia -
Technique Permits Scale Gains in the Production of Materials with Graphene
Publicado em 19 janeiro 2019A group of Brazilian researchers have developed strategies to produce polymer-graphene nanocomposites on an industrial scale. The isolation of graphene crystals is one of the most significant recent advances in science and technology, first performed in 2004 and awarded the Nobel Prize for Physics in 2010. However, the creation of graphene nanocomposites with plastics still occurs basically in the laboratory. “On a small scale, solvents and other techniques are used and work well in [...]ver notícia -
Artificial Magnetic Field Produces Exotic Behavior in Graphene Sheets
Publicado em 11 dezembro 2018A simple sheet of graphene has noteworthy properties due to a quantum phenomenon in its electron structure named Dirac cones in honor of British theoretical physicist Paul Dirac (1902-1984), who was awarded the Nobel Prize for Physics in 1933. The system becomes even more interesting if it comprises two superimposed graphenesheets, and one is very slightly turned in its own plane so that the holes in the two carbonlattices no longer completely coincide (see video below). For specific [...]ver notícia -
Biosensor promises early malaria diagnosis
Publicado em 03 fevereiro 2018Speed read - Sensor uses strip paper similar to that of rapid pregnancy tests - It detects falciparum malaria protein in under 30 minutes - Device could be useful for endemic hard-to-reach populations SÃO PAULO] - A strip of chromatography paper similar to that used in rapid pregnancy tests is the basis of a bio-sensor for detecting malaria that has been developed by Brazilian researchers. The strip, designed for early diagnosis of infection caused by the Plasmodium falciparum parasites [...]ver notícia
