Physicochemical Characterization and Asymmetric Catalytic Properties of New Biobased Organocatalytic Surfactants

open access: yesMolecules
In organic synthesis, the solvent is the chemical compound that represents the largest proportion of the process. However, conventional solvents are often toxic and dangerous for the environment, and an interesting alternative is to replace them by water.

Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...

Accounting for Substitution: Improving Estimates of GHG Reductions From Cattle‐Based Product Demand Shifts

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Estimates of reductions in greenhouse gas (GHG) emissions from lower demand for cattle‐based products must account for substitution effects. This study collected data through two surveys—one on ground beef and another on dairy milk—to evaluate substitution effects and potential GHG reductions.

Chemical Upcycling of Nitrile Butadiene Rubbers to Polyamines and Polyols by Chemoselective Catalytic Hydrogenation

open access: yesAngewandte Chemie, EarlyView.
We demonstrate here the transformation of NBR (Nitrile butadiene rubber) including post‐consumer waste sourced from nitrile gloves and o‐rings into polyamines and polyols via ruthenium catalyzed hydrogenation. ABSTRACT We report here two new approaches for the chemical recycling/upcycling of nitrile butadiene rubber (NBR) to make either polyamines or ...

Inhibition of Aflatoxin B1 Production by Procyanidins Present in Annona muricata and Uncaria tomentosa Aqueous Extracts

open access: yesToxins
Aflatoxin B1 (AFB1), primarily produced by Aspergillus flavus and A. parasiticus, is the most dangerous mycotoxin for humans and contaminates a variety of crops.
