Abstract The present study focuses on the Preparation of Aluminum Oxide, and Copper oxide antifouling coatings to prevent or reduce corrosion fouling in ships marine vehicles. Al 2 O 3 CuO nanoparticles were prepared using ball milling process. nano paints these as pigment linseed alkyd resin a binder. Mild-steel specimens coated with paint immersed seawater for 120 days properties studied Scan...

Phosphor-free apple-white light emitting diodes have been fabricated using a dual stacked InGaN/GaN multiple quantum wells comprising of a lower set of long wavelength emitting indium-rich nanostructures incorporated in multiple quantum wells with an upper set of cyan-green emitting multiple quantum wells. The light-emitting diodes were grown on nano-epitaxially lateral overgrown GaN template f...

The principal objective of the present work is to conduct investigations leading to a more complete explanation of natural convective heat transfer in a partitioned cavity utilizing nano fluids. The nano fluid used, which is composed of Aluminum oxide nano particles in suspension of Ethylene glycol, has been provided at various particle concentrations ranging from 0 to 30% in volume. The study ...

Nanofabrication technologies have been a strong advocator for new scientific fundamentals that have never been described by traditional theory, and have played a seed role in ground-breaking nano-engineering applications. In this study, we fabricated ultra-high-aspect (∼10(6) with O(100) nm nanochannel opening and O(100) mm length) orthogonal nanochannel array using only polymeric materials. Ve...

Metalorganic vapor phase epitaxy (MOVPE) nucleation studies of GaN on planar sapphire and nanopatterned AGOG (Deposition of Aluminum, Growth of Oxide, and Grain growth) sapphire substrates were conducted. The use of abbreviated GaN growth mode, which utilizes a process of using 15 nm low-temperature GaN buffer and bypassing etch-back and recovery processes during epitaxy, enables the growth of ...
