Fabrication of Organic Solar Cells with Branched Cauliflower-Like Nano Structures as a Back Electrode Replicated from a Natural Template of Cicada Wing Patterns
Nanostructures of noble metal materials have been used in organic solar cells for enhancement of performance and light trapping. In this study, we have introduced branched silver cauliflower-like nanopatterns as sub-wavelength structured metal grating in organic solar cells. Self-assembled fabrication process of branched nanopatterns was carried out on a bio-template of cicada wing nanonipple a...
متن کاملSynthesis of stable ACC using mesoporous silica gel as a support
Stable amorphous calcium carbonate supported by mesoporous silica gel was successfully synthesized. The silica gel support is prepared through the hydrolytic polycondensation of ethyl silicate under suitable conditions. Laser scanning confocal microscopy (LSCM) observations reveal that the morphology of the products is branched with cruciform-like and flower-like structure. Raman spectroscopic ...
متن کاملCharacterization of Chiral Carbonaceous Nanotubes Prepared from Four Coiled Tubular 4,4′-biphenylene-silica Nanoribbons
Four dipeptides derived from phenylalanine were synthesized, which can self-assemble into twisted nanoribbon in deionized water. The handedness of the organic self-assemblies was controlled by the chirality of the phenylalanine at the terminals. Coiled 4,4′-biphenylene bridged polybissilsesquioxane tubular nanoribbons were prepared using the organic self-assemblies as the templates. The circula...
متن کاملBranched silica nanostructures oriented by dynamic G-quadruplex transformation
Polymorphic G-quadruplexes including stacked G-quartet planes are potentially promising DNA templates beyondWatson-Crick duplexes to construct inorganic nanostructures. In this work, a novel Grich oligonucleotide that can be modulated from the antiparallel G-quadruplex to multi-stranded supermolecular assemblies was designed. Based on this dynamic G-quadruplex transformation, an interesting lea...
متن کاملMesoporous monoliths of inverse bicontinuous cubic phases of block copolymer bilayers.
Solution self-assembly of block copolymers into inverse bicontinuous cubic mesophases is a promising new approach for creating porous polymer films and monoliths with highly organized bicontinuous mesoporous networks. Here we report the direct self-assembly of block copolymers with branched hydrophilic blocks into large monoliths consisting of the inverse bicontinuous cubic structures of the bl...
