Resolving a Nearly Two‐Centuries‐Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide

Chemistry – A European Journal, EarlyView.
The crystal structure of ammelide, also known as melanuric acid, was solved almost 200 years after its discovery by Liebig. Moreover, three modifications of its 1:1 adduct with ammeline were structurally elucidated, consisting of layers with a honeycomb motif analogous to melamine cyanurate.

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 ...

Supercritical water deasphalting and desulphurization of heavy fuel oil with comprehensive molecular‐level analysis and techno‐economic analysis

The Canadian Journal of Chemical Engineering, EarlyView.
Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.

Acid‐Catalyzed Synthesis of Si‐Stereogenic Silanes

Chinese Journal of Chemistry, EarlyView.
Si‐stereogenic silanes are important structural motifs in chemical synthesis, medicinal chemistry, and materials science. However, their catalytic enantioselective synthesis has largely relied on transition‐metal catalysts. Recently, Brønsted acids have been developed as promising alternatives.
