Surface Forces in Foam Films
Fundamental studies of surface forces in foam films are carried out to explain the stability of foams and froths in froth flotation. The thin film pressure balance (TFPB) technique was used to study the surface forces between air bubbles in water from equilibrium film thickness and dynamic film …

Effect of Non-Ionic Surfactants and Nano-Particles on the Stability of Foams
The thin film pressure balance (TFPB) technique were used to study the stability of single foam films produced in the presence of n-alkyl polyoxyethylene (CnEOm) homologues. The results showed that films thin faster than predicted by the classical DLVO theory, which considers contributions from the …

Biodegradable food packaging using agricultural wastes (Banana Pseudostem)
… this research was to study the properties of the film made from the nanocellulose. Modifications to the film were done to improve the quality of the film by incorporating plasticisers (glycerol and polyethylene glycol (PEG)) and nanofillers (nanoclay and graphene oxide) into the nanocellulose …
