Polyphenols from green tea were used to electrolessly deposit gold on silk cocoons (SCs) and nanoporous aluminum oxide (AAO) templates. The gold coated cocoons were used as electrodes in supercapacitors and showed a capacitance as high as 254 F g(-1) and a specific power of 2287 W kg(-1). A metal coated AAO template was used for molecular separation.

This thesis aims at the synthesis of oriented nanochannel systems for the synthesis of metallic or semiconducting nanowires. Three different synthesis strategies have been developed. First, horizontal macroto mesoporous anodic aluminum oxide (AAO) structures with individually addressable channel systems were fabricated in collaboration with the group of Dr. Anna Fontcuberta at TU München. For t...

We report chemical modification of self-assembled block copolymer thin films by ultraviolet light that enhances the block-selective affinity of organometallic precursors otherwise lacking preference for either copolymer block. Sequential precursor loading and reaction facilitate formation of zinc oxide, titanium dioxide, and aluminum oxide nanostructures within the polystyrene domains of both l...

9-Methylanthracene (9MA) undergoes a concerted [4 + 4] photodimerization in its crystal form that can be harnessed order to generate photomechanical motions such as bending, twisting, and expansion. As described this paper, 9MA nanowires were grown anodic aluminum oxide (AAO) templates with the goal of using expansion net increase height composite disk. The growth conditions optimized raise fil...

fe49co33ni18 nanowire arrays (175 nm in diameter and lengths ranging from 5 to 32μm) were fabricated into nanopores of hard-anodized aluminum oxide templates using pulsed ac electrodeposition technique. hysteresis loop measurements indicated that increasing the length decreases coercivity and squareness values (from 274 oe and 0.58 to200 oe and 0.105, respectively), indicating the increase in m...
