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

Purification of Li2CO3 Obtained through Pyrometallurgical Treatment of NMC Black Mass from Electric Vehicle Batteries

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Lithium carbonate (Li2CO3) obtained from the black mass of recycled lithium batteries is dissolved in water under controlled conditions to remove lithium fluoride (LiF), which is present at a concentration of 3.08 % by weight. The dissolution is carried out at temperatures below 10 °C, and it has been demonstrated that lower temperatures result in ...

Dynamics of bubble absorption over porous membranes in an immersed medium

open access: yesDroplet, EarlyView.
The dynamics of a bubble interacting with a flat, porous superhydrophobic membrane underwater has been illustrated. Abstract Porous superhydrophobic (SHP) membranes are gaining considerable attention due to their excellent underwater absorption and drag reduction properties. They exploit the Cassie‒Baxter state of wetting to remove the bubble in a fast

Effects of joint geometric configurations on cyclic shear behavior of intermittent joints under constant normal stiffness conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...
