Bond Formation: Shaken, Not Stirred

Chemistry – A European Journal, EarlyView.
Shaking of seismo‐molecules efficiently transforms kinetic energy into storable chemical potential, unlocking high‐utility Gibbs free energy. This innovative mechanism pioneers uncharted scientific frontiers, introducing fascinating phenomena like seismochemistry, seismochromism, and seismofluorescence that redefine the boundaries of molecular ...

Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Analysis of Radial Heat Transfer in Cooled Fixed‐Bed Reactors by One‐ and Two‐Dimensional Models

Chemie Ingenieur Technik, EarlyView.
Exothermic fixed‐bed reactors are analyzed using 1D and 2D models. Radial temperature profiles from the 2D model enable optimization of the 1D approach via adjusted overall heat transfer coefficient. Derived correlations improve prediction accuracy, whereas thermal runaway behavior and model sensitivity are evaluated. ABSTRACT Exothermic reactions in a

Laminar Burning Velocity of Ammonia‐Hydrogen Mixtures Predicted by Machine Learning

Chemie Ingenieur Technik, EarlyView.
Ammonia–hydrogen blends aid defossilization, but slow combustion kinetics require complex modeling. Although chemical kinetic modeling is computationally expensive, machine learning surrogates offer fast predictions. This study trained GPR, DT, and ANN models on 1445 experimental points.

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.
