ClearHydrophobisation of Silica Nanoparticles Using Lauroyl Ethyl Arginate and Chitosan Mixtures to Induce the Foaming Process
Silica nanoparticles were coated with a mixture of chitosan and a biodegradable surfactant to make them partially hydrophobic and capable of stabilizing foam films. The study found that small amounts of the surfactant promoted foam formation by reducing the surface tension around the nanoparticles. Stable biodegradable foams have potential applications in food processing and environmental cleanup.

Attachment of various-shaped polystyrene microplastics to silica surfaces: Experimental validation of the equivalent Cassini oval extended DLVO model
Researchers experimentally studied the attachment of differently shaped polystyrene microplastics — spheres, fibres, and fragments — to silica surfaces under varying ionic strength and pH conditions. Particle shape strongly influenced attachment rate and strength, with fibres showing higher attachment efficiency than spheres due to greater contact area, with implications for predicting microplastic fate in porous soils and sediments.
