Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

open access: yesChemistry – A European Journal, EarlyView.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

AutoVap: An Interactive Machine Learning Tool for Predicting the Standard Enthalpy of Vaporization

open access: yesChemie Ingenieur Technik, EarlyView.
AutoVap (https://autovap.jfcaetano.com) is a web app that predicts ΔvapHm° from SMILES using an RDKit‐based ML model, giving accurate, interpretable results with uncertainty across diverse molecules. ABSTRACT This communication introduces AutoVap (https://autovap.jfcaetano.com), an interactive web application for predicting the standard molar enthalpy ...

An Assessment of World Hydrocarbon Resources

open access: yes, 1996
Assessments of global coal, oil, and natural-gas occurrences usually focus on conventional hydrocarbon reserves, i.e., those occurrences that can be exploited with current technology and present market conditions. The focus on reserves seriously underestimates the long-term availability of global hydrocarbons.

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
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 ...

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...
