Improving the Efficiency of a Bioreactor Equipped With Mixed‐Flow Impellers

Chemical Engineering &Technology, EarlyView.
The present work investigated the biological performance of mixed‐flow impellers. To the authors’ knowledge, this is the first experimental study on such impellers in a fermentation process using A. vinelandii, which was chosen as a microorganism due to its high oxygen demand.

Transformative Catalytic Carbon Conversion Enabling Superior Graphitization and Nanopore Engineering in Hard Carbon Anodes for Sodium‐Ion Batteries

Carbon Energy, EarlyView.
A hard carbon material distinguished by abundant nanopores, low defects, and extended curved graphite domains was synthesized in a straightforward manner using a catalytic process aided by zinc gluconate. During carbonization, trace amounts of zinc single atoms remain within the hard carbon.

Continuous Flow Synthesis of β‐Aminoketones as Masked Vinyl Ketone Equivalents

Chemistry – A European Journal, Volume 31, Issue 19, April 1, 2025.
We report an efficient and scalable method for the generation of β‐aminoketones from amides and Grignard reagents. The continuous process operates at elevated temperatures and uses a plate‐based reactor exploiting a hydrophobic internal coating to avoid reactor fouling issues due to the heterogeneous reaction mixture. The unmasking of the β‐aminoketone

Synthesis of Ag@Pd Nanocubes and Pd‐based Nanoframes via One‐Shot Injection of a Halide‐Free Precursor for Continuous Production in a Flow Reactor

Chemistry – A European Journal, Volume 31, Issue 23, April 22, 2025.
We report the synthesis of Pd‐based nanoframes by templating with Ag nanocubes via one‐shot injection of Pd(NH3)4(NO3)2 solution and H2O2 etching. We also extend the one‐shot synthesis from a batch to a continuous flow reactor for continuous production without compromising the quality.

CO Generation from CO2 Using an Atmospheric Microwave Plasma Process

Chemie Ingenieur Technik, Volume 97, Issue 5, Page 479-486, May 2025.
Due to the increasing concentration of CO2 in the atmosphere and the resulting man‐made climate change, alternatives to fossil fuels must be found. The chemical industry is looking for alternative processes. One promising possibility is atmospheric pressure microwave plasma, which converts CO2 into CO using electrical energy.

Towards Systemic Leadership Resilience: Proposing the Hybrid Artificial Intelligent Leader in Response to Economic Crises

Canadian Journal of Administrative Sciences / Revue Canadienne des Sciences de l'Administration, EarlyView.
ABSTRACT Researchers now understand that the Great Recession stemmed from a “systemic leadership failure,” involving various entities such as the government, financial institutions, investors, homeowners, and regulators. Consequently, traditional leadership approaches of the time came under intense scrutiny, necessitating a shift in leadership ...

Experimental and model‐based investigation of the droplet size distribution during the mixing process in a batch‐settling cell

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The design of a liquid–liquid gravity settler relies on the experimental investigation and model‐based description of the phase separation process in a batch‐settling cell. However, according to the current state of the art, the modelling assumes a monodisperse droplet size distribution (DSD), which can lead to an inaccurate settler design ...

Investigation of liquid distribution in gas–solid fluidized beds for fluid cokers

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Thermal cracking processes convert larger molecules into smaller, more valuable products, without a catalyst, allowing for transforming residual oils or waste plastics into useful compounds. Fluid coking, a thermal cracking process utilizing a fluidized bed of hot particles, processes approximately 1 million barrels of residual oil daily. This
