Selected properties of photovoltaic (PV) structures based on n-type zinc oxide nanorods grown by a low temperature hydrothermal method on p-type silicon substrates (100) are investigated. PV structures were covered with thin films of Al doped ZnO grown by atomic layer deposition acting as transparent electrodes. The investigated PV structures differ in terms of the shapes and densities of their...

The reaction of single-component molecular crystal nanorods with a second species to form cocrystal nanorods is described. Single-component crystalline nanorods, composed of 9-methylanthracene (9-MA), are grown in a porous anodic aluminum oxide template. These templated rods are then exposed to a suspension of 1,2,4,5-tetracyanobenzene (TCNB) in water, which slowly diffuses into the 9-MA rods o...

This article presents a study on the growth process for the template-based growth of TiO2 nanorods by sol electrophoretic deposition, through both experiment and simulation. Uniformly sized nanorods of approximately 45–200 nm in diameter and 10–60 μm in length can be grown over large areas with near unidirectional alignment. The nanorods have the desired stoichiometric chemical composition and ...

Silver nanorods (Ag NR) have been successfully synthesized by wet chemical method (seed-mediated growth) utilizing 10 nm silver nanospheres as a seed material and subsequent reduction of silver precursor with a weak reducing agent (ascorbic acid) along with a directing surfactant. The effect of synthesis temperature on the structure, morphology, composition and optical properties were investiga...

We report a novel technique for generating polymer fluorescent barcode nanorods by reactive ion etching of polymer multilayer films using nonclose-packed (ncp) colloidal microsphere arrays as masks. The fluorescent polymer multilayer films were spin-coated on a substrate, and ncp microsphere arrays were transferred onto these films. The exposed polymers were then etched away selectively, leavin...

In this work, Co3O4 nanorods were successfully prepared by microwave-assisted solid state decomposition of rod-like CoC2O4.2H2O precursor within a very short reaction time (6 min) without the use of a solvent/surfactant and complicated equipment. The as-obtained Co3O4 nanorods were fully characterized by X-ray diffract...

High-quality, ordered nanopores in semiconductors are attractive for numerous biological, electrical, and optical applications. Here, GaN nanorods with continuous pores running axially through their centers were grown by organometallic vapor phase epitaxy. The porous nanorods nucleate on an underlying (0001)-oriented GaN film through openings in a SiN(x) template that are milled by a focused io...

We show that a relatively simple approach for controlling the colloidal synthesis of anisotropic cadmium selenide semiconductor nanorods can be extended to the size-controlled preparation of magnetic cobalt nanorods as well as spherically shaped nanocrystals. This approach helps define a minimum feature set needed to separately control the sizes and shapes of nanocrystals. The resulting cobalt ...

The catalytic CO hydrogenation is one of the most versatile large-scale chemical syntheses leading to variable chemical feedstock. While traditionally mainly methanol and long-chain hydrocarbons are produced by CO hydrogenation, here we show that the same reaction can be tuned to produce long-chain n-aldehydes, 1-alcohols and olefins, as well as n-paraffins over potassium-promoted CoMn catalyst...
