“…Polyaniline (PANI) microtubes were electropolymerized at +0.80 V for 0.02 C (0.1 C for membrane with 5 µm pore size) from a plating solution containing 0.1 M H 2 SO 4 , 0.5 M Na 2 SO 4 and 0.1 M aniline; subsequently, the inner zinc tube was deposited galvanostatically at -6 mA for 1800 sec (2400s for membrane with 5 µm pore size) from a commercial zinc plating solution containing 80 g l −1 ZnSO 4 , and 20 g l −1 H 3 BO 3 solutions (buffered to pH = 2.5 with sulfuric acid). [2] The sputtered gold layer was completely removed by hand polishing with 3-4 µm alumina slurry. The membrane was then dissolved in methylene chloride for 10 min to completely release the microtubes.…”

Hydrogen-Bubble-Propelled Zinc-Based Microrockets in Strongly Acidic Media

Tubular polyaniline (PANI)/Zn microrockets are described that display effective autonomous motion in extreme acidic environments, without any additional chemical fuel. These acid-driven hydrogen-bubble-propelled microrockets have been electrosynthesized using the conical polycarbonate template. The effective propulsion in acidic media reflects the continuous thrust of hydrogen bubbles generated by the spontaneous redox reaction occurring at the inner Zn surface. The propulsion characteristics of PANI/Zn microrockets in different acids and in human serum are described. The observed speed–pH dependence holds promise for sensitive pH measurements in extreme acidic environments. The new microrockets display an ultrafast propulsion (as high as 100 body lengths/s) along with attractive capabilities including guided movement and directed cargo transport. Such acid-driven microtubular rockets offer considerable potential for diverse biomedical and industrial applications.

“…Its natural abundance and extended tunability into the ultraviolet range make Al a promising material for future plasmonic applications . To date, Al nanostructures (e.g., 2D nanopatterns and 1D nanowires (NWs), and nanotubes (NTs)) are mainly fabricated by top‐down lithographic methods, including electron beam lithography (EBL), nanosphere lithography (NSL), and anodized aluminum oxide (AAO) template lithography . For bottom‐up, self‐assembled growth, wet chemical methods are restricted to the fabrication of noble metal (e.g., Au, Ag, Pt) nanostructures , though there have been reports of stress‐induced , electromigration‐induced and vapor‐phase growth in glancing angle deposition of Al microwires and nanowires.…”

The use of aluminum (Al) as a plasmonic building block has drawn increasing attention of late, due to its natural abundance, and extended tunability into the ultraviolet range. However, a controllable way to grow Al nanowires (NWs) in a bottom-up manner has not been reported. Here a facile, stress-induced growth process for Al nanowires, influenced by the concentration of applied hydrofluoric acid, is reported. Physical characterizations show the nanowires to be polycrystalline fcc Al with ultrasmooth surfaces, with many possible cross-section geometries, making them potential candidates for Al plasmonic investigations and applications. Dark-field optical analysis of a crescent-shaped Al NW demonstrates its plasmonic nature. These results may stimulate new interest in the fabrication of unconventional, nearly one dimensional Al nanostructures.

“…Handbook 2015 With the use of anodic alumina, light polarizers are being assembled. AC and DC electrodeposition techniques are being employed to deposit Ag [199], Co [254], Cu [198], and Ni [219] to form parallel nanowire arrays serving as polarizers. Nanowire-AAO composite polarizers are attractive devices for infrared wavelengths.…”

Anodic aluminum oxide (AAO) consists of parallel pores arranged in a honeycomb-like array. Since a two-step self-organized approach in anodic alumina fabrication was invented, tremendous attention was paid to this material. Structural features of anodic alumina, like pore diameter, interpore distance, and nanoporous oxide thickness, can be fully controlled by operating conditions, including type, concentration and temperature of the electrolyte, applied voltage, and duration of the anodization process. Moreover, these operating conditions have also a major impact on the nanoporous array arrangement. Quantitative arrangement analysis methods employing fast Fourier transforms have been developed to assess the nanopores' arrangement. The most frequent application of the anodic aluminum oxide is a template-assisted fabrication of nanostructures. Templates made of the AAO are being successfully applied in fabrication of nanowires, nanotubes, and nanodots by using diversity of techniques, including electrochemical deposition, physical and chemical vapor deposition, sol-gel techniques, etc. Due to the size of obtained nanostructures, magnetic, electric, piezoelectric, luminescent, and catalytic properties of the deposited materials can be significantly improved. Thus, control of the nanopores' structural features and arrangement is crucial for AAO applications in nanotechnology.
