The creation of drag-reducing surfaces in deformed tubes is vital importance to thermal management, energy, and environmental applications. However, it remains a great challenge tailor the surface structure wettability inside slim complicated feature. Here, we describe an electrochemical anodization strategy achieve uniform superhydrophobic coating TiO2 nanotube arrays throughout inner deformed...

Nickel-titanium-oxide (Ni-Ti-O) nanotube arrays (NTAs) prepared on nearly equiatomic NiTi alloy shall have broad application potential such as for energy storage and biomedicine, but their precise structure control is a great challenge because of the high content of alloying element of Ni, a non-valve metal that cannot form a compact electronic insulating passive layer when anodized. In the pre...

Effects of constant temperature and humidity testing on the adhesive properties phosphate-anodized AZ91D magnesium alloy were evaluated to produce multiple materials for lightening fabrication these materials. Phosphate-anodized alloy, after immersion in dilute nitric acid solution, maintained strong strength even testing. These findings suggest that anodization film is bonded chemically by sol...

In an attempt to quantify grain boundary diffusion of hydrogen in nickel, permeation in electrodeposited foil has been investigated. Pinhole-free specimens were plated from a nickel sulfamate bath onto a reusable anodized titanium cathode. The microstructure was a mixture of regions of fine grains (diameters <0.1 tm) and individual grains up to 2 tm in diameter. The specimens were subjected to ...

To enhance biocompatibility and osseointegration between titanium implants and surrounding bone tissue, numerous efforts have been made to modify the surface topography and composition of Ti implants. In this paper, Lenti-BMP-2-loaded TiO2 nanotube coatings were fabricated by lyophilization in the presence of trehalose to functionalize the surface. We characterized TiO2 nanotube layers in terms...

STATEMENT OF PROBLEM The aim of this study was to study the effects of various surface treatments to a titanium surface on the expression of Runx2 in vitro. MATERIAL AND METHODS Human Osteosarcoma TE-85 cells were cultured on machined, sandblasted, or anodic oxidized cpTi discs. At various times of incubation, the cells were collected and then processed for the analysis of mRNA expression of ...
