Aerosol Science & Environmental Health
Real-time particle measurement, gas analysis, metals chemistry, respiratory-deposition concepts and toxicology — for users and bystanders alike.
Research
Research at the interfaces of process engineering, environment, materials and health.
Fabrice's publication record spans several application areas, but the underlying engineering questions are consistent: how do material properties and operating conditions govern transport, reaction, separation, exposure and performance — and how can that understanding improve real systems?
The unifying question
How do materials, particles, interfaces and operating conditions interact to control process performance, environmental release and human exposure?
This single question frames an unusually broad portfolio. The work reads as a sequence of engineering scales: without this hierarchy the publication list could look fragmented; with it, the site shows a scientist-engineer repeatedly studying how microscale behavior creates macroscale process and environmental outcomes.
Five engineering scales
From interfaces to decisions.
Every project in the record lives at one or more of these scales — and most connect a smaller scale to a larger one.
Material / interface scale
Catalyst interfaces, metal oxidation state, emulsion interfaces, nanoparticle chemistry.
Particle / phase scale
Aerosol size, droplets, suspended solids, mineral particles.
Process scale
Separation, leaching, flotation, reaction, filtration, tailings and resource recovery.
Exposure / environmental scale
Secondhand aerosols, respiratory deposition, water treatment, waste valorization.
Decision scale
Safety, sustainability, risk, operational improvement and responsible engineering.
Research themes
Publications Five themes, one engineering lens.
Sustainable Mineral & Critical-Material Processing
Flotation, copper/cobalt leaching, tailings, rare-earth recovery and process improvement — emphasizing resource efficiency and responsible recovery.
Rheology & Multiphase Systems
Highly concentrated emulsions: shear stability, breakup, droplet behavior and process-relevant flow, plus crude-oil demulsification.
Sustainable Materials & Environmental Remediation
Waste-to-material concepts: stabilized iron nanoparticles from acid mine drainage and rooibos tea, applied to Fenton-like water treatment.
Catalysis & Carbon Utilization
Inverse oxide/metal catalyst concepts for converting CO₂ and hydrogen to methanol, connecting catalyst structure and interfaces with sustainable manufacturing.
