This paper describes a simple technique for fabricating uniform arrays of metal and metal oxide nanotubes with controlled heights and diameters. The technique involves depositing material onto an anodized aluminum oxide (AAO) membrane template using a collimated electron beam evaporation source. The evaporating material enters the porous openings of the AAO membrane and deposits onto the walls ...

This thesis presents a series of three related studies with the aim of developing a surface that promotes robust dropwise condensation. Due to their remarkably low droplet adhesion, superhydrophobic surfaces were investigated for application to dropwise condensation. Although precise model superhydrophobic surfaces were necessary to gain insight into these phenomena, it was recognized that wide...

Carbon fiber reinforced polymer (CFRP) is widely used in the lightweight design of high-speed trains due to its high specific strength. In order further reduce weight train body, it necessary study joining process and fatigue properties CFRP/aluminum alloys (CFRP/Al) structure. this work, CFRP plate 5083P-O aluminum were successfully connected by an induction brazing method. The optimum paramet...

Rapid formation of a porous alumina film without oxide burning was achieved by anodizing in etidronic acid at large current densities using nanodimpled aluminum surface. After the electropolished specimens were galvanostatically anodized 0.3 M solution 293 K, uniform formed relatively low up to 20 Am−2. first process, an array dimples fabricated on surface removal chromic acid/phosphoric soluti...

Herein, a novel method is proposed to synthesize B-ZnO NWA by simply immersing the Zn in NaOH solution at room temperature (25 °C). Based on systematic investigation of various factors that affect growth NWA, mechanism clarified. Guided mechanism, control morphology achieved adjusting pore structure anodized aluminum oxide templates, hot-pressing parameters, concentration, temperature, and imme...

Coloring of anodized aluminum（alumite）with organic pigment was investigated. After alumite prepared by anodic oxidation aluminum in oxalic acid solution, pore-widening done with solution at 323 K（50 ℃）. Then iron or nickel metal deposited electrochemically pores. Pigment particles dispersed surfactant an azobenzene moiety（AZPEG）were the pores reduction AZPEG and nickel.

Nervous systems are composed of microstructured scaffolds with three-dimensional nanofeatured textures. These textures enable the systems to give nanometer-scaled physical cues to the overlying cells, along with biochemical cues. However, the topographical effects on the neurons are still an unexplored territory, although there have been many reports on the biochemical cues for neuronal behavio...
