Industry relevant microfluidic platforms for mineral leaching experiments
Published in Frontiers in Chemical Engineering
Microfluidic and lab-on-a-chip devices offer exquisite temporal and spatial control over chemical and physical processes that are important in mineral exploration and mining. These include mineral-water interfacial reactions, dissolution, and adsorption/desorption in pores, fractures, or other micro/nanostructures. Microfluidic mineral studies offe...
2D simulation of temperature distribution within large-scale PEM electrolysis stack based on thermal conductivity measur...
Published in Frontiers in Chemical Engineering
Polymer electrolyte membrane electrolyser cells (PEMEC) are recognized as highly suitable for large-scale green hydrogen production from variable renewable sources. To enhance production rates in PEMECs, current densities have gradually increased, resulting in elevated heat generation within the electrolysis cells. Consequently, the consideration o...

Generative artificial intelligence in chemical engineering spans multiple scales
Published in Frontiers in Chemical Engineering
Recent advances in generative artificial intelligence (GenAI), particularly large language models (LLMs), are profoundly impacting many fields. In chemical engineering, GenAI plays a pivotal role in the design, scale-up, and optimization of chemical and biochemical processes. The natural language understanding capabilities of LLMs enable the interp...
Comparative study on lubrication properties of biodiesel and bio-lubricant trans-esterified from desert seed oil with co...
Published in Frontiers in Chemical Engineering
In recent years, there has been an increasing focus on renewable and biodegradable energy sources among lubricant manufacturers due to the environmental impacts and limited availability of fossil-based engine oils. Biomass sources present a cost-effective and eco-friendly alternative to traditional mineral oil sources. This study aims to produce an...
Numerical modeling and experimental validation of fluid flow in micro- and meso-fluidic siphons
Published in Frontiers in Chemical Engineering
Siphons have been used for thousands of years to transfer fluids without the use of pumps or power and are present in our daily lives. Paradoxically, it is only in recent decades that the operation of siphons has been fully clarified, which is now understood to be exclusively linked to gravity and molecular cohesion. Siphons are uniquely able to of...
Revealing the role of magnetic materials in light-driven advanced oxidation processes: enhanced degradation of contamina...
Published in Frontiers in Chemical Engineering
Semiconductor photocatalysis, heterogeneous photo-Fenton and heterogeneous photocatalytic persulfate activation are light-driven advanced oxidation processes (AOPs) that have attracted much attention as promising technologies in wastewater treatment. Nevertheless, their large-scale application still faces several challenges, including the need to s...
BYG-drop: a tool for enhanced droplet detection in liquid–liquid systems through machine learning and synthetic imaging
Published in Frontiers in Chemical Engineering
A new image processing machine learning algorithm for droplet detection in liquid–liquid systems is here introduced. The method combines three key numerical tools—YOLOv5 for object detection, Blender for synthetic image generation, and CycleGAN for image texturing—and was named “BYG-Drop for Blender-YOLO-CycleGAn” droplet detection. BYG-Drop outper...
Numerical evaluation of methanol synthesis in catalytic wall-coated microreactors: scale-up and performance analysis of ...
Published in Frontiers in Chemical Engineering
Methanol is one of the most important primary chemical compounds, being an interesting alternative for portable energy applications and also acting as a molecular platform for the synthesis of a wide range of commodities and high-added-value products. Traditionally, methanol is obtained by catalytic hydrogenation using synthesis gas (CO/CO2/H2) in ...
