Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

Macaúba (Acrocomia aculeata) pulp oil ethylic biodiesel using lipase from Aspergillus oryzae: kinetic and process parameters

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Macaúba (Acrocomia aculeata), a native species from Brazilian biomes, has emerged as a sustainable alternative to vegetable oil production. Its fruit presents high oil yield (3–6 ton/ha), extracted from its kernel and pulp. While the kernel is suitable for food and cosmetics application, the pulp oil has been considered as a promising ...

Unveiling opportunities and challenges for a circular approach to macaúba biorefining: a technological roadmap

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The macaúba fruit, native to tropical and subtropical regions, has received considerable attention in recent years as a promising raw material for the production of advanced biofuels in Brazil. However, the development of large‐scale biomass requires overcoming significant challenges, such as designing circular biorefineries.
