Synthesis of Biginelli adducts using a Preyssler heteropolyacid in silica matrix from biomass building block
(Elsevier Inc, 2018-12)
An efficient, suitable and high yielding method has been developed employing the use of the renewable platform molecule furfural for the synthesis of Biginelli derivatives via a three-component domino reaction through a ...
Evolution of the South Atlantic passive continental margin in southern Brazil derived from zircon and apatite (U-Th-Sm)/He and fission-track data
(2013-09-24)
The area between São Paulo and Porto Alegre in southeastern Brazil plays a key area to understand and quantify the evolution of the South Atlantic passive continental margin (SAPCM) in Brazil. In this contribution, we ...
