Preparing an Exsolvable Ru‐Substituted LaFeO3 Perovskite With High Surface Area From a Self‐Sacrificial Polymer Template: A Versatile Strategy for Enhanced Catalytic Performance

Chemistry – A European Journal, EarlyView.
High‐surface‐area LaFe0.9Ru0.1O3 is prepared by infiltration of porous Amberlite XAD16 polymer beads. Ru exsolution of this perovskite material leads to a supported catalyst with small Ru particles, exhibiting promising catalytic performance propane combustion.

Strong Implications From Small Deviations in Labeling Patterns: The Mechanism of Burkholderia gladioli Pacifigorgiadiene Synthase

Chemistry – A European Journal, EarlyView.
The mechanism of pacifigorgiadiene synthase from Burkholderia gladioli was investigated through isotopic labeling experiments and DFT calculations. The results revealed an unexpected labeling pattern which appeared to be different in the main and the side products, requiring unprecedented mechanistic explanations, including a “break‐flip‐cyclise ...

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.

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

The 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 ...

A‐optimal model‐based design of experiments for processes with uncertain inputs

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Model‐based design of experiments (MBDoE) techniques are tools for selecting experimental conditions that enable accurate parameter estimation for mechanistic models. Most MBDoE approaches assume that the selected experimental conditions will be implemented perfectly, without uncertainties in the independent variables.

Valorization of Juice Industry Waste Into Foam‐Like Materials Using Mycelium as Natural Binder

CleanMat, EarlyView.
This study explores converting carrot pomace, a juice industry byproduct, into eco‐friendly mycelium‐based foams using Aspergillus oryzae. The foams, produced via submerged cultivation, grinding and freeze‐drying, showed promising mechanical properties comparable to commercial foams, offering a sustainable alternative to synthetics while promoting ...

Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...
