Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum ox...

In this paper, optimal conditions for fabrication of nanoporous platinum (Pt) were investigated in order to use it as a sensitive sensing electrode for silicon CMOS integrable non-enzymatic glucose micro-sensor applications. Applied charges, voltages, and temperatures were varied during the electroplating of Pt into the formed nonionic surfactant C16EO8 nano-scaled molds in order to fabricate n...

InGaN light emitting diodes (LED) structure with an embedded 1/4λ-stack nanoporous-GaN/undoped-GaN distributed Bragg reflectors (DBR) structure have been demonstrated. Si-heavily doped GaN epitaxial layers (n(+)-GaN) in the 12-period n(+)-GaN/u-GaN stack structure are transformed into low refractive index nanoporous GaN structure through the doping-selective electrochemical wet etching process....

Low refractive index thin films have generated substantial interest for use in optical devices particularly in Light Emitting Diodes (LEDs). Applications include photonic cavities, mirrors, etc. Such films are required to have precise control over both thickness and refractive index. Here, we investigate fabrication of Omni Directional Reflectors (ODRs) using nanoporous silica films. Sub-100 nm...

tris(3-bromo-acetylacetonato) chromium(iii) as an inert and very stable complex with a good leaving group was synthesized using as-prepared cr(acetylacetonate)3. highly ordered nanoporous silica (lus-1), with some great features, was functionalized with 3-aminopropyltriethoxysilane. then the as-prepared product was modified with tris(3-bromo-acetylacetonato) chromium(iii) under mild reaction co...

We report that the proton-coupled electron transfer kinetics of 1,4-benzoquinone was significantly enhanced in electrified nanopores in aqueous media. At nanoporous Pt and Au electrodes, the voltammetric behaviour of 1,4-benzoquinone at nanoporous electrodes was clearly distinct from that at flat surfaces. Proton transfer as well as electron transfer kinetics were facilitated in the nanopores b...
