چکیده
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 filling amount from 28% 77% available volume porous AAO. A new experimental method for detecting motion, based on analysis data dynamically misaligned Michelson interferometer, was developed. Template bending observed, showing confined generated mechanical work, but no conclusive evidence surface disruption or vertical translation observed. Optical measurements, well atomic force scanning electron microscopy, showed incomplete filling, orientation, debris template polishing likely prevented observation actuation these nanocrystal composites. This work highlights some practical challenges are involved creating actuators organic–inorganic approach, two most significant being (1) uniform organic active material (2) removal excess template’s surface.

Fabrication of nanomaterials using porous alumina templates
Nanofabrication by self-organization methods has attracted much attention owing to the fact that it enables mass production without the use of expensive lithographical tools, such as an electron beam exposure system. Porous alumina can be fabricated electrochemically through anodic oxidation of aluminum by means of such a self-organization method, yielding highly ordered arrays of nanoholes sev...
متن کاملElectrochemical self-assembly of porous alumina templates
Porous alumina templates are fabricated by anodization of Al in an acid. The characteristics of the template, such as the pore diameter, interpore separation, and the periodicity of the porous structure depend on the conditions of anodization and the acid that is used as electrolyte. The variation of pore diameter and interpore separation as a function of anodization parameters are described. T...

The giant magnetoresistance GMR of multilayered Co/Cu nanowires potentiostatically electrodeposited inside the pores of an anodized alumina template was studied in the current perpendicular to the plane CPP geometry. The maximum magnetoresistance change of 13.5% was observed for Co 8 nm /Cu 10 nm nanowires at room temperature. The interfacial roughness and/ or an intermixing between Co and Cu l...
متن کاملThe synthesis of alumina nanowires on the surface of a porous alumina membrane
Porous aluminum oxide membranes with a complete and even covering of alumina nanowires were formed in a one-step anodization process in dilute phosphoric acid electrolyte. The anodizing conditions can be adjusted to start forming alumina wires that originate on the surface of the porous alumina layer at the triple junction points (the edges of the hexagonal inter-pore structure where three pore...
متن کاملFabrication of Nanostructured Thin Films using Porous Alumina Templates
We demonstrate a method for fabricating a variety of nanostructured metallic thin films by using one simple approach based on the use of anodic aluminum oxide (AAO) membrane as masking template. Highly-ordered large-area metallic nanoporeor nanotip-arrays (e.g., Ni, Ag, Au), with various sizes and shapes, were deposited onto AAO membranes through e-beam evaporation. Free standing nano-patterned...
