Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Solvent‐Driven Pore Engineering in Coffee‐Derived Activated Hydrochar: Implications for Post‐Combustion CO2 Capture

open access: yesCarbon Energy, EarlyView.
Solvent washing of coffee‐ground hydrochars produces activated carbons with tunable pore sizes while maintaining surface area. Removing non‐polar contaminants enhances microporosity, increasing CO2 uptake by 40%. Moderate pore sizes (9–12 Å) yield optimal CO2:N2 selectivity, whereas smaller pores reduce selectivity due to stronger interactions between ...

Revisiting acidulation for tall oil and lignin manufacturing

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...
