5. 3. Ordered arrays of low-dimensional Au and Pd : synthesis and in situ observations

   Author : Giuseppe Abbondanza; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanowires NWs ; nanorods; nanoparticles; Au; Pd; Al; Al2O3; anodization; nano-porous anodic aluminum oxide; powder diffraction; x-ray diffraction; x-ray scattering; SAXS; WAXS; grazing-incidence; two-dimensional surface optical reflectance;

   Abstract : Electrodeposition of metals in templates of nano-porous anodic aluminum oxide (NP-AAO) is a versatile way of fabricating ordered arrays of metal nanowires. Thanks to the self-arranged long-range hexagonal order of the pores, electrodeposition in NP-AAO is an easily scalable bottom-up synthesis route and an attractive alternative to traditional top-down fabrication methods such as electron beam lithography.

   Abstract : Nanocomposites (NCs) have been widely studied in the past decades due to the promising properties that nanoparticles (NPs) offer to a polymer matrix, such as increased thermal stability and non-linear electrical resistivity. It has also been shown that the interphase between the two components is the key to achieving the desired improvements. READ MORE
