The polydispersity index and zeta potential increased subsequently upon ultrasonication from 0.22 to 0.48 and −12 to −21 mV confirming narrow range of particle size distribution and enhanced colloidal stability. The SEM of non-treated whey showed dense spherical structure whereas upon ultrasonication the structure of protein granules changes to polygon.

The ultrasonicated and native whey were characterized for functional properties viz. foaming, emulsifying, water and oil absorption capabilities. The solubility and hydrophobicity of whey before and after ultrasonication were determined. The WPI had higher hydrophobicity than ultrasonicated WPI which could be owed to the protein unfolding due to acoustic cavitation effect of ultrasonication. Water and oil absorption capacity of WPI were also affected by ultrasonication, water absorption capacity was decreased whereas oil absorption capacity was increased upon ultrasonication. The nutraceutical properties of WPI viz. antioxidant, antimicrobial, antihypertensive, antilipidemic, and antiproliferative activities were also found to increase significantly upon ultrasonication.

Employing a custom-designed ultrasound attenuation measurement setup, we measured the frequency-dependent attenuation of MBs, isolating MBs based on size to generate distinct monodisperse sub-populations for analysis.

However, dislocation pinning due to the incoherent interfaces in MoS₂/TiO₂ coatings tends to cause localized stress concentrations and brittle fracture, requiring effectively improve nanomechanical properties by optimizing interface design. To address these issues, this study used ultrasonic-assisted PEO to disperse graphene oxide (GO), which provided more possibility for <em>in-situ</em> synthesis MoS₂, ultimately resulting in MoS₂ with modified interlayer spacing. The change in interlayer spacing induced dislocation evolution at incoherent interface, leading to dual interface formation. At MoS₂ (0.534 nm)/TiO₂ interface: dislocation dipoles evolve to create considerable distortion, facilitating releasing shear stresses and inhibiting crack propagations. This process is followed by dislocation annihilation, keeping to stable interfacial bonding. Additionally, the others form strong dislocation pinning to obstruct dislocation slip and enhancing deformation resistance at MoS₂ (0.227 nm)/TiO₂ interface. The combined effects of dual interfacial enhancements resulted in a 90.0 % reduction in friction coefficients of the MoS₂/GO/TiO₂ coating compared to the traditional ceramic coating.
