Exploration of agricultural residue ash as a solid green heterogeneous base catalyst for biodiesel production

Engineering Reports, Volume 5, Issue 1, January 2023., 2023
Transesterification of vegetable oils with homogeneous catalyst for biodiesel synthesis is considered to have a promising future, but it is nonrenewable and hazardous. High production cost, in terms of feedstock oil and catalyst acquisition is one of the major challenges facing the global commercialization of biodiesel.

Beyond Carbon: The Contributions of South American Tropical Humid and Subhumid Forests to Ecosystem Services

Reviews of Geophysics, Volume 60, Issue 4, December 2022., 2022
Abstract Tropical forests are recognized for their role in providing diverse ecosystem services (ESs), with carbon uptake the best recognized. The capacity of tropical forests to provide ESs is strongly linked to their enormous biodiversity. However, causal relationships between biodiversity and ESs are poorly understood.

Science‐based planning can support law enforcement actions to curb deforestation in the Brazilian Amazon

Conservation Letters, Volume 15, Issue 6, November/December 2022., 2022
Abstract While Brazil publicly committed to reduce deforestation in Amazonia at the 26th Conference of the Parties (COP26), the Brazilian parliament is moving toward weakening environmental laws. Deforestation rates continue ascending, reaching in 2021 the highest value since 2006 (13,235 km2). To overcome this paradox, strategies to curb deforestation
