Pyrrolic‐Nitrogen‐Enriched Aerogels With Magnetic Responsiveness Enable Cooperative Hydrogen‐Bond Regulation for High‐Performance Solar Interfacial Evaporation

Carbon Energy, EarlyView.
A pyrrolic‐nitrogen‐enriched ferromagnetic aerogel enables sophisticated cooperative regulation of hydrogen bonding, whereby this dual‐regulatory mechanism effectively reduces vaporization enthalpy while simultaneously enhancing molecular dynamics. The system demonstrates exceptional self‐cleaning capability and exhibits superior performance in the ...

HYDRO-DISTILLATION VERSUS STEAM DISTILLATION FOR CLOVE OIL PRODUCTION

Journal of Chemical Technology and Metallurgy
The production of clove essential oil by hydro distillation and steam distillation has been experimentally investigated. The density of the oil was determined to be ρ ≈ 1.0648 g cm-3. By means of hydro-distillation, a higher yield of 9.714 mass % was obtained compared to the steam distillation - 4.986 mass %.

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 ...
