Kamafugite Magma Pathways and Lava‐Flow Paleotopography From Three‐Dimensional Audiomagnetotelluric Imaging Constrained by Borehole Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract An audiomagnetotelluric (AMT) survey was conducted within the Alto Paranaíba Igneous Province, southeastern Brazil, to delineate shallow occurrences of kamafugite, a rare ultrapotassic volcanic rock worldwide. A dense grid of AMT stations was deployed, allowing the construction of a high‐resolution 3D electrical resistivity model ...

Integrated bioconversion of starchy and hemicellulosic fractions of macauba oil presscake into ethanol by nonconventional yeasts

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 779-792, March/April 2026.
Abstract Co‐fermentation of hexoses and pentoses from plant biomass to ethanol is a strategy to increase ethanol production from lignocellulosic materials and add value to residues from agroindustrial chains. The macauba (Acrocomia aculeata) is an oleaginous palm‐tree species considered to contribute to development in some regions of Brazil.
