I’m both surprised and grateful to find myself included — from 2021 to 2024 — in the global ranking compiled by Stanford University, identifying the top 2% most influential scientists worldwide. This recognition is based on a bibliometric analysis of citation impact, using data from Scopus. Link to the source What is the Stanford Ranking? […]
Abstract The present study offers a predictive correlation for oxygen transfer based on the exhaustive analysis of more than 300 isolated gas bubbles and the examination of interfacial colonization phenomena occurring in the presence of surfactants. The correlation is formulated by accounting for two key aspects: the hydrodynamic influence exerted by surfactants on mass transfer […]
Abstract Cinematic and pop culture narratives offer powerful tools for engaging with science by contextualizing complex principles within familiar, imaginative stories. This paper investigates the scientific feasibility of a plan depicted in Godzilla Minus One to neutralize the iconic kaiju through buoyancy reduction, exposure to deep-sea pressure, and rapid decompression. Employing principles from fluid mechanics, […]
Abstract Exocrine Pancreatic Insufficiency (EPI), induced by conditions such as cystic fibrosis, chronic pancreatitis, and Crohn’s disease, is a frequently overlooked and underdiagnosed gastrointestinal disorder. It leads to inadequate intestinal digestion due to insufficient secretion of pancreatic juice, resulting in discomfort, pain, and ultimately severe malnutrition. Despite numerous treatments proving ineffective over the past three […]
Abstract Axisymmetric numerical simulations of the hydrodynamics around rising bubbles are performed in order to investigate the impact of surfactants on the bubble dynamics. Surfactants are assumed to be insoluble. The transport of the adsorbed surfactants is computed along the deforming surface at large surface Péclet number, and Marangoni stresses are taken into account. This […]
Abstract Biogas upgrading is becoming essential in the valorization path for biogas. Biomethane from anaerobic digestion is identified to be one of the main resources to decarbonize the energy requirement. However, small-scale (especially farm-scale) applications suffer from a lack of implementation worldwide, mainly limited by the cost of the upgrading process. As one of the most used technologies, High Pressure […]
Abstract N-alkyl-D-galactonamides give biocompatible hydrogels that are very delicate and not injectable. To circumvent their mechanical fragility and the injectability issue, we have developed a method of injection based on solvent-water exchange. A solution of the gelator in a good solvent is injected vertically in a bath of water. The diffusion of water inside the solvent jet […]
Abstract Direct Numerical Simulations are performed to investigate the gas-liquid mass transfer around a rising spherical bubble contaminated by insoluble surfactants. The surfactant transport on the bubble surface and the Marangoni effect are taken into account when solving the hydrodynamics, resulting in the stagnant-cap condition. A parametric study is carried out to investigate the mass transfer by varying the Reynolds, […]
Abstract This article focuses on the study of the mass transfer involved in the application of a bacterial antifouling technique for membrane bioreactors (MBR), via the addition of solid media. These alginate objects can contain a biological system capable of producing an enzyme that degrades the signal molecules responsible for membrane fouling. The objective of […]
Abstract Planar Laser Induced Fluorescence with Inhibition (PLIF-I) is a powerful technique for studying the local gas/liquid oxygen mass transfer from a single rising bubble. However, to track oxygen in the liquid phase, it is necessary to use an oxygen sensitive luminescent probe, which needs to be unreactive toward the liquid phase. This article presents […]
