Linear alkyl chain dependent structure-performance correlation of Trialkyl phosphates for Lithium extraction

open access: yesChemical Engineering Journal. Green and Sustainable
Against surging global lithium demand, salt lake brine lithium recovery is essential to stable lithium supply. With simple operation and flexible selectivity, solvent extraction is industrially favorable, yet traditional extractants suffer low efficiency

Impact of cover crop termination timing on the soil microbiome of regenerative no‐till cotton in Texas

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Optimizing cover crop termination timing (CCTT) is crucial for ensuring sustainable cover crop management under regenerative agriculture. This study investigated how early and delayed CCTTs interact with irrigation regimes to affect soil microbiomes, arbuscular mycorrhizal fungi (AMF) dynamics, and the root‐associated fungal biome in cotton ...

Design and Optimization of a Double‐Column Vapor Recompression Heat Pump Distillation Process via NSGA‐II for Separating Ternary Wide‐Boiling Mixtures

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 5, September/October 2026.
ABSTRACT This study proposes a novel double‐column vapor recompression heat pump (DCVRHP) distillation process for separating ternary wide‐boiling‐range mixtures under two different vapor conditions: n‐hexane/n‐heptane/n‐octane using low pressure steam and n‐hexanol/n‐octanol/n‐decanol using high pressure steam.

Synthesis and utilization of new extractants for nuclear hydrometallurgy

open access: yes, 1995
Recent progress in organic chemistry increases the possibility of controlling metal ions/organic molecules interaction. The use of macrocycles or polypodands (1) makes possible the creation of specific extractants for each metal ion.
