Efficient Recycling of Spent LiCoO2 Cathodes Via Confined Pore‐Assisted Simplified Direct Carbothermic Reduction Without External Reducing Agents

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A simplified direct carbothermic reduction (SDCR) process is developed for efficient recycling of spent LiCoO2 cathodes. The SDCR method employs carbon conductive agents and organic binders embedded in the electrode as internal reducing agents, while the confined pores of calendered electrodes promote the retention of in situ generated reduction gases.

Cholesteryl Fatty Acid Esters and Free Cholesterol in Food of Animal Origin

European Journal of Lipid Science and Technology, EarlyView.
Cholesterol occurs in free (bioavailable) and esterified (transport/storage) forms. Here, we present a method that allows both forms to be determined independently. Finally, the quantities of free and esterified cholesterol were determined in several meat, animal fat, and cheese samples.

Sustainability in Analytical Chemistry Illustrated by Pharmaceutical Nitrosamine Testing

ELECTROPHORESIS, EarlyView.
ABSTRACT Following the valsartan scandal in 2018, the testing of drug substances and drug products for N‐nitrosamines has become a critical and mandatory quality control measure. The European Pharmacopoeia chapter 2.5.42 currently describes three analytical methods for this purpose: HPLC–MS/MS, GC–MS, and GC–MS/MS.

Vanillin production from lignin depolymerization by acidic deep eutectic solvent and its possible mechanism

Environmental Progress &Sustainable Energy, EarlyView.
Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...
