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

open access: yesBiofuels, 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.

Numerical simulation of supercritical-fluid flows over arbitrary geometry

open access: yesJournal of Fluid Science and Technology, 2014
In this study, numerical simulations of supercritical-water flows over an arbitrary geometry are presented. In the present method, the supercritical-fluids simulator (SFS) developed by the authors is coupled with the building-cube method (BCM).

Permeation of supercritical CO2 through dense polymeric membranes

open access: yes, 2019
Supercritical carbon dioxide (scCO2) is used in the food industry as a water-extracting drying agent. Once saturated with water, the scCO2 needs to be regenerated. A promising way of drying scCO2 is by using H2O permeable membranes.

Bioeconomy, sustainability, and digital technologies in Haematococcus lacustris biomass and astaxanthin production: advances and outlook

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...

Solvation in supercritical water [PDF]

open access: yes, 1991
The aim of this work is to determine the solvation structure in supercritical water composed with that in ambient water and in simple supercritical solvents. Molecular dynamics studies have been undertaken of systems that model ionic sodium and chloride,

Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...

Bismuth‐Based Semiconductors in Photocatalytic CO2 Reduction: Catalysts, Progress, and Future Perspectives

open access: yesCarbon and Hydrogen, EarlyView.
This review systematically summarizes research progress on bismuth‐based semiconductor photocatalytic materials in the field of CO2 reduction. It focuses on elucidating the mechanisms by which four modification strategies—including heteroatom doping, oxygen vacancy engineering, microstructural control, and heterostructure fabrication—regulate band ...
