Open AccessPhotoelectrochemical properties of doped TiO2 nanowires grown by seed-assisted thermal oxidation
Titanium dioxide Nanowires (NWs) are particularly interesting because of their very high surface/volume ratio and their photocatalytic activity allows them to be used in a myriad of applications. This manuscri...

Open AccessMechanical milling: a sustainable route to induce structural transformations in MoS2 for applications in the treatment of contaminated water
Two-dimensional (2D) nanomaterials have received much attention in recent years, because of their unusual properties associated with their ultra-thin thickness and 2D morphology. Besides graphene, a new 2D mat...

Open AccessNovel synthesis of ZnO/PMMA nanocomposites for photocatalytic applications
The incorporation of nanostructured photocatalysts in polymers is a strategic way to obtain novel water purification systems. This approach takes the advantages of: (1) the presence of nanostructured photocata...

Open AccessEffect of Pt Nanoparticles on the Photocatalytic Activity of ZnO Nanofibers
For this study, we originally realized ZnO nanofibers (∼50 nm in mean radius) mixed with Pt nanoparticles (∼30 nm in mean radius), prepared by pulsed laser ablation in liquid, and investigated their photocatal...

Open AccessTiO2-coated nanostructures for dye photo-degradation in water
The photocatalytic efficiency of a thin-film TiO2-coated nanostructured template is studied by dye degradation in water. The nanostructured template was synthesized by metal-assisted wet etching of Si and used as...

Open AccessVisible and infrared emission from Si/Ge nanowires synthesized by metal-assisted wet etching
Multi-quantum well Si/Ge nanowires (NWs) were realized by combining molecular beam epitaxy deposition and metal-assisted wet etching, which is a low-cost technique for the synthesis of extremely dense (about 1011

Indirect Diffusion Mechanism of Boron Atoms in Crystalline and Amorphous Silicon
The diffusion of B atoms in crystalline and amorphous Si has been experimentally investigated and modeled, evidencing the indirect mechanism of these mass transport phenomena. The migration of B occurs after i...

Suppression of Boron Diffusion by Fluorine Implantation in Preamorphized Silicon
We have investigated the role of fluorine in the reduction of transient enhanced diffusion (TED) and thermal diffusion (TD) of B in preamorphized Si layers implanted with F. For this purpose, we have employed ...
