Nanoporous anodic aluminum oxide (AAO) templates are fabricated using an anodization method. The mean diameters of nanoporous anodic aluminum oxide templates are 100 nm and 200 nm by various processing parameters of the anodization method. A molded plastic thin film nanostructure is fabricated by nanoimprinting using the AAO template as a mold. The surface properties of the molded plastic thin film are discussed using various nanoimprinting process parameters. Contact angles of the molded plastic thin film with the nanostructure exceed those without the nanostructure. The molded plastic thin f

Abstract:

AbstractPorous anodic aluminium oxide (AAO) template is commonly used in the synthesis of one-dimensional nanostructures, such as nanowires and nanorods, due to its simple fabrication process. Controlling the anodizing conditions is important because of their direct influence on the size of AAO template pores; it affects the size of nanostructures that are fabricated in AAO template. In present study, several alumina templates were fabricated by a two-step electrochemical anodization in different conditions, such as the time of first process, its voltage, and electrolyte concentration.

Abstract:

A tilted cathode was adopted to change the distribution of the electric field during the second anodization of the two-step method for fabricating nanoporous anodic alumina (NanoPAA). A variety of controllable patterns of NanoPAA templates were firstly prepared. After that, the functional nanostructures of alumina such as nanowires and nanobelts were accomplished by chemically etching the NanoPAA templates with phosphoric acid. In addition, the formation mechanisms of alumina nanopores and diverse low dimensional nanostructures influenced by the modified electric field were also discussed from

Abstract:

Porous anodic aluminum oxide (AAO) is deposited on a 5 cm × 5 cm tin-doped indium oxide (ITO)/glass substrate, and the AAO/ITO/glass structure thus formed is used to reduce the amount of unreacted Al inside the AAO template, thereby reducing the transmittance of the AAO/glass structure. The enhancement of transmittance is achieved by modulating the diameter of the pores and varying the applied bias. The proposed AAO can be used at a high applied bias (up to 120 V) to improve the uniformity of the current density. Following pore-widening treatment and posttreatment annealing, the morphologies a

Abstract:

Nano-structured polymer stamps were prepared from porous anodic alumina templates. Prepolymers were poured onto the highly ordered porous anodic alumina templates, and they were cured by UV-irradiation. Simple separation of the elastic stamp from the nanoporous aluminum oxide leads to well replicated nano-stamps. The nanopatterns on the stamp were transferred as ultrahigh-density nanopore arrays on various substrates which are potentially applicable to the fabrication of ultrahigh-density metallic or semiconductor nanodot arrays for magnetic storage devices or display devices.

Abstract:

Self-organization of a two-dimensional array of nanopores, which was formed by anodic oxidation of aluminum, was investigated quantitatively using scanning electron microscopy (SEM) images and their fast Fourier transformation analysis. The highly ordered array of nanopores with diameters of ~60 nm was obtained by two-step anodization at an anodizing voltage of 40 V for an anodizing time of 36 h in a 0.3 M oxalic acid. A two-dimensional ordered array of ferroelectric PbTiO3 nanotubes was successfully fabricated by a spin coating of sol-gel solution into porous anodic alumina template. SEM and

Abstract:

To obtain a large surface area, the aluminum electrode foils (AEF) were etched by direct current (DC) in hot chloride solution to get lots of vertical [001] tunnels. Whereas, because of the defects as rolling trace, distorted oxidation film, non-uniform organization, pollution layer on the surface of the aluminum foil, and the easy corrosion in hot Cl- acid solution, the etch pits are disorder and merged. These merged pits cause laterally directed dissolution and excessive dissolution on the aluminum surface, which limited the surface enlarging and decreased the strength of the aluminum foils.

Dense and mesoporous FePd nanowires (NWs) with 45 to 60 at.% Pd content were successfully fabricated by template- and micelle-assisted pulsed potentiostatic electrodeposition using nanoporous anodic alumina and polycarbonate templates of varying pore sizes. An FePd electrolyte was utilized for obtaining dense NWs while a block copolymer, P-123, was added to this electrolyte as the micelle-forming surfactant to produce mesoporous NWs. The structural and magnetic properties of the NWs were investigated by electron microscopy, X-ray diffraction, and vibrating sample magnetometry. The as-prepared

Abstract:

There has been great hope for ultrasensitive detection methods with the application of Surface Enhanced Raman Spectroscopy (SERS) because of its impressive advancements. Nevertheless, a major challenge is the creation of large-scale, controllable, and reproducible substrates with high SERS activity [1]. As a basis for SERS detection, we report here the fabrication of different types of aluminum-based and polymer-based SERS platforms with the synthesis of gold nanoparticle (AuNP) arrays on them. The tunability of the AuNPs size and distribution is achieved by methodically controlling the alumin

Abstract:

Anodic alumina template containing hexagonally ordered nanopores has been widely used over the last decade for the development of numerous functional nanostructures such as nanoscale sensors, computing networks, optoelectronic devices, thin film micro circuits, ultra filtration membranes, keying layers for organic adhesives to hard, wear and corrosion resistant layers and memories. The long range pore order requires the starting aluminum surface to be extremely smooth. Electropolishing is the most commonly used method for surface planarization prior to anodization. While prevalent, this method

Abstract:

Color tunability of perovskite light emitting diodes (PeLEDs) by mixed halide compositional engineering is one of the primary intriguing characteristics of PeLEDs. However, mixed halide PeLEDs are often susceptible to color red-shifting caused by halide ion segregation. In this work, strongly quantum-confined perovskite nanowires (QPNWs) made of CsPbBr3 are grown in nanoporous anodic alumina templates using a closed space sublimation (CSS) process. By tuning the pore size with atomic layer deposition (ALD), QPNWs with diameter of 6.6 nm to 2.8 nm have been successfully obtained, with continuou

Abstract:

For the oxidation of water to dioxygen, oxide-covered ruthenium metal is known as the most efficient catalyst, however, with limited stability. Herein, we present a strategy for incorporating a Ru/C composite onto a novel nanoporous electrode surface with low noble metal loading and improved stability. The Ru/C is coated on the pore walls of anodic alumina templates in a one-step laser-induced deposition method from Ru3(CO)12 solutions. Scanning electron microscopy proves the presence of a continuous Ru/C layer along the inner pore walls. The amorphous material consists of metallic Ru incorpor
