Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Carbonylation reactions offer a sustainable route to valuable carbonyl compounds. This review highlights methodologies that exploit carbonylative coupling to drastically enhance process sustainability, avoiding the direct use of CO through CO surrogates and promoting syntheses in green solvents potentially derived from renewable and sustainable sources.

Diagenetic evolution of some modern and ancient cold seep-carbonates from East Coast Basin, New Zealand.

open access: yes, 2009
Cold seep-carbonates are the microbially mediated by-products of the anaerobic oxidation of methane (AOM) at seafloor cold seeps, and are widespread about modern continental margins and in the geologic record.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1683-1707, July/August 2026.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1762-1780, July/August 2026.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Low-frequency acoustic classification of methane hydrates [PDF]

open access: yes, 2011
textMethane hydrates are naturally-occurring ice-like substances found in permafrost and in ocean sediments along continental shelves. These compounds are often the source of cold seeps—plumes which vent methane into aquatic environments, and may ...

Emerging research directions in nanoparticle‐based foam control for bioprocessing: a bibliometric approach

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1708-1728, July/August 2026.
Abstract Overfoaming remains a critical challenge in industrial bioprocesses, compromising mass transfer, operational stability, and downstream efficiency in bioreactors and wastewater treatment systems. This study provides a bibliometric and scientometric assessment of nanoparticle‐enabled foam control to map technological trends and identify research

Carbon Dioxide Sequestration using Methane Hydrates

open access: yes, 2018
Climate change has been talked about a lot. Climate control is synonymous with an effort to reduce CO2 emissions or find ways to sequester it. One such method gaining mileage is CO2 sequestration into methane hydrates.
