Mid‐Infrared Spectroscopy and Machine Learning for Chlorogenic Acid Quantification in Coffee
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 ...

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.

Investigations Into the Human Metabolism of Trestolone (7α‐Methyl‐19‐Nortestosterone)
As the known metabolites of 7α‐methyl‐19‐nortestosterone (MENT), M1 and M2, suffer from chromatographic issues under routine doping control conditions, the human metabolism of MENT was reinvestigated. From the numerous new metabolites detected, especially, M5 and M10 were identified as the most promising candidates to be implemented into routine ...
