Carbon 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 ...

Novel Bioactive Multifunctional Polyphenols: A Chemo‐Enzymatic Approach
Chemistry – A European Journal, EarlyView.One‐step synthesis of complex alkyl oxystilbenin glucosides (6‐47% yield) in alcoholic medium. Switching to ter‐BuOH as solvent afforded δ‐Viniferin diglucoside, with high selectivity and high yield (> 90%), that can be upgraded by enzymatic esterification to alkyl δ‐Viniferin diglucosides.

A Riboflavin‐Derived Flavinium Salt Mediates Chemoselective Methylation Reactions
Chemistry – A European Journal, EarlyView.A two‐component methylation protocol was developed, where the active flavin mediator can be recycled in a single step. Crystallographic data and NMR spectroscopy support the mechanistic proposal, while chemoselective methylation was observed for a broad range of biologically relevant substrates. ABSTRACT Selective methylation is among the most relevant

Mid‐Infrared Spectroscopy and Machine Learning for Chlorogenic Acid Quantification in Coffee
Chemie Ingenieur Technik, EarlyView.Chlorogenic acid (CGA) concentration in coffee was predicted using mid‐infrared (MIR) spectroscopy and a machine learning approach. Forty‐four roasting stages (140–220 °C) plus a green coffee control were analyzed. A multilayer perceptron regressor, trained on preprocessed MIR data, outperformed traditional peak analysis, enabling accurate and ...
