A strategy to halt dissolution of particle-coated air bubbles in water based on interfacial rheology design is presented. Whereas previously a dense monolayer was believed be required for such an "armored bubble" resist dissolution, fact engineering 2D yield stress interface suffices achieve performance at submonolayer particle coverages. We use suite techniques characterize spherical and ellipsoidal particles air-water as function surface coverage. Bubbles with varying coverages are made...
We investigate the mechanism of self-assembly fatty acids (FA) and methyl oleate on an Al oxy-hydroxide surface with a view to deciphering role nature interfacial processes (adsorption, chemical binding, molecular organization, etc.). For this purpose, we focus parameters related intrinsic properties molecules, namely level unsaturation head group (carboxylic acid or ester). After FA adsorption, presence coordinative bonded carboxylate species is demonstrated by means PM-IRRAS analysis....
The self-assembly of fatty acids (FA) on the surfaces inorganic materials is a relevant way to control their wetting properties. While mechanism adsorption model flat substrate well described in literature, interfacial processes remain poorly documented nanostructured surfaces. In this study, we report variety FA hydroxylated Al surface which exhibits random nanoscale organization. Our results revealed peculiar fingerprint due consists formation aligned nanopatterns state hierarchical...
We study particle capture at a microfluidic air–liquid interface and highlight the effects of confinement on colloidal adsorption.
Purpose Workmanship concerns lead to more focus on volatile materials, released by industrial lubricants. Typically, flash point test and thermo‐gravimetrical analysis (TGA) are used investigate basestock volatility, but they do not address long‐term decomposition tendencies of The extent losses due chemical degradation (oxidation, hydrolysis, dissociation, etc.) remains unclear. Design/methodology/approach Vaporisation eight additive‐free bio‐based, synthetic mineral basestocks with similar...
Herein, we report the coating of a surface with random nanoscale topography lipid film formed by an anchoring stearic acid (SA) monolayer and phospholipid (DPPC) layers. For this purpose, different procedures were used for coating, including adsorption from solution, drop deposition, spin-coating. Our results reveal that morphology obtained films is strongly influenced underlying substrate but also impacted other factors, procedure wettability (modulated presence SA). These coated surfaces...
Understanding the wetting properties of chemically modified inorganic surfaces with random nanoscale topographies is fundamental importance for diverse applications. This issue has hitherto continuously been subject considerable controversies. Herein, we report a thorough investigation wettability–topography–chemistry balance nanostructured surface topography, main challenge being decoupling topography from chemistry. For this purpose, use superficially aluminum substrate by fatty acid...

Foams are inherently unstable objects, that age and disappear over time. The main cause of foam aging is Ostwald ripening: smaller air bubbles within the empty their gas content into larger ones. One strategy to counter ripening consists in creating armored bubbles, where solid particles adsorbed at air/liquid interface prevent from shrinking below a given size. Here, we study efficiency coating with fat crystals bubble dissolution. A monoglyceride, monostearin, directly crystallized air/oil...
Abstract Volatile materials, released by lubricants, relate to various engineering, occupational and workmanship aspects. Most tests (flash point, NOACK, TGA etc.) assess thermodynamic evaporation without focusing on prolonged oxidation hydrolysis, which can also produce volatiles, especially in unsaturated esters. A thin film test was adapted for long‐term (2000 h+) vaporisation studies dry or humid atmosphere. Rapeseed oil oleate esters showed initial weight gain due peroxide formation at...
