Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.

A Review of the Use of Chemical Stabilisation Methods for Lithium‐Ion Batteries

Battery Energy, EarlyView.
The review reveals that while chemical stabilisation techniques for recycling EOL LIBs are widely used, many studies overlook safety risks, focusing on quick, low‐cost methods. Only a few studies address the associated hazards, highlighting the need for safer, well‐understood stabilisation processes in battery recycling. ABSTRACT The increasing amounts

Brazilian Biomes as Promising Resources of Rhodotorula Yeasts for the Biotechnological Production of Carotenoids

Chemistry &Biodiversity, EarlyView.
ABSTRACT Yeasts belonging to the genus Rhodotorula are capable of synthesizing carotenoids, such as β‐carotene, γ‐carotene, torulene, torularodine, and astaxanthin. These carotenoids have been shown to offer health benefits to humans, such as immune system strengthening and a reduced risk of chronic degenerative diseases.
