Advanced Materials, EarlyView.An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels
Advanced Materials Interfaces, EarlyView.When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

LUBRICATING OILS ON THE BASIS OF NANOLIQUIDS [PDF]
Physical and Chemical Aspects of the Study of Clusters, Nanostructures and Nanomaterials, 2018 We established applicability of dispersed medium based on diesters of carbonic acids for production the low-viscosity magnetic oil of new generation. It was shown unusual approach to select surfactant-stabilizer for colloidal structure of oils considering their dielectric properties and friction effects.
