The immersion of a material, seeded with ZnO nanoparticles, in an aqueous solution of Zn(NO3)2 and hexamethylenetetramine (HMT) at 90 °C yields an extended array of one-dimensional ZnO on the substrate surface. The structure of the ZnO evolves with

Growth of ZnO nanostructures on c-plane sapphire has been investigated using three different methods. Pulsed laser deposition (PLD) at low incident pulse energies can yield nanorods, the majority of which are aligned at an angle of ∼50° to the sub

International audience; Noble metals-promoted tungstated oxides have been shown to be profitable in a wide variety of catalytic reactions of environmental interest but to be detrimental in the hydrogenation of aromatics. The origin of the deleterious

Two different organic monolayers were prepared on silicon Si(111) and modified for attaching gold nanoparticles. The molecules are covalently bound to silicon and form very ordered monolayers sometimes improperly called self-assembled monolayers (SAM

Transmission electron microscopy was used to investigate epitaxial ZnO films on c-sapphire, produced by a two-step method. Firstly, pulsed laser deposition provided a continuous buffer ZnO, with thickness about 80 nm and a predominant alignment of (0
