TLDR
Replica molding against an elastomeric mold has been used to fabricate packing cells to be used for the crystallization of mesoscopic, spherical colloids into three-dimensionalally ordered arrays over relatively large areas as discussed by the authors.Abstract:
Replica molding against an elastomeric mold has been used to fabricate packing cells to be used for the crystallization of mesoscopic, spherical colloids into three-dimensionally ordered arrays over relatively large areas. The capability and feasibility of this method have been demonstrated by the production of homogeneous, opaline lattices of 255 or 467 nm polystyrene beads over areas as large as ∼0.5 cm2. These 3D crystalline lattices of mesoscopic colloids are useful for fabricating new types of diffractive optical components, for producing porous materials, and for generating photonic bandgap structures. We believe the demonstration of a replica molding procedure for the fabrication of the packing cells should make the crystallization method more useful to those who have no direct access to clean-room facilities.read more

The application of inverse titania opals in nanostructured solar cells
TL;DR: In this article, the synthesis and characterization of nanostructured heterojunction solar cells based on inverse opal titanium dioxide (TiO2) films is discussed, where the voids between the spheres are filled with a TiO2 precursor and a subsequent heat treatment yields a highly organized porous structure.

Method and apparatus for fabricating shaped structures and shaped structures including one- , two- or three-dimensional patterns incorporated therein
TL;DR: In this paper, a template for the fabrication of devices having one, two, or three dimensional geometries was proposed, which can include at least a first patterned surface and a mask integrated into the template for creating an interference pattern.
