Abstract Siam Kintamani oranges are very popular nowadays. Its bioactive compounds such as phenolics, carotenoids, vitamins, minerals, and fiber beneficial for health. The weakness of Siamese is that the quality quickly declines. can be maintained by applying coating. Nanocoating applications from natural materials currently needed to reduce coatings synthetic materials. This support a green ec...

Interaction between two surfaces in relative motion can give rise to energy dissipation and hence sliding friction. A significant portion of the energy is dissipated through the creation of non-equilibrium phonons. Recent advances in material synthesis have made the production of specific single layer honeycomb structures and their multilayer phases, such as graphene, graphane, fluorographene, ...

Plasma nanocoated films with trimethylsilane-oxygen monomers showed outstanding biocompatibility in our previous studies. In this study, endothelialization on biomedical nitinol alloy surfaces was systematically investigated. Our study focuses on elucidating the effects of surface micropatternings with micropores and microgrooves combined with plasma nanocoating. Plasma nanocoatings with contro...

Prolonged exposure to ultraviolet (UV) radiation from the sun can result in several skin problems, such as accelerating aging, burns, blemishes, or even cancer. Even when wearing clothes, there is still a risk that user will be exposed UV and suffer damage. Therefore, it necessary apply anti-UV treatments clothes fabrics used, so users become safe. Nitrogen doped graphene quantum dots (N-GQD) t...

This paper presents a mathematical model for bi-directional convection magnetohydrodynamic (MHD) tangent hyperbolic nanofluid flow from the upper horizontal subsurface of stretching parabolic surface to non-Darcian porous medium, as simulation nanocoating. Chemical reaction, activation energy and thermo solutal buoyancy effects are included. The Darcy–Brinkman–Forchheimer is deployed which perm...
