TiO2 nanotubes decorated with Au nanoparticles for Photocatalytic Hydrogen Generation under UV-Visible and Visible Light Irradiations.

The development of stable and active TiO2 nanotubes (NTs) decorated with plasmonic gold nanoparticles (Au NPs) represents a strategy for charge-transfer processes improvements. However, organic capping ligands used for Au NPs synthesis usually remain on the surface of the metal, leading to poor Schottky junctions between Au and TiO2. Herein, we report on the synthesis of a nanotubular matrix of TiO2 decorated with gold without the need of ligands.

Extensive clinical, serologic and molecular studies lead to the first reported Rh phenotype in Argentina.

Background: A highly reduced expression of Rh antigens in the erythrocyte membrane is the main feature of Rh , an extremely rare phenotype. Mutations within RHAG gene, which encodes RhAG glycoprotein and modulates Rh antigen expression and Rh complex formation, are the molecular events responsible for the Rh phenotype. Here we report a clinical, serologic, and molecular study of an Argentinean proband with Rh-deficiency syndrome.

New strategy to obtain high surface area anatase nanotube/AuNP photocatalyst.

Anatase nanotubes with high surface area (ca. 350 m g), containing gold nanoparticles, were successfully obtained from trititanate nanotubes, prepared by a template-free hydrothermal method, and calcined at 450 °C. The high surface area and tubular morphology were attained due to the presence of ionic silsesquioxane, which acts as anti-sintering agent for titania during calcination process, by forming a thin silica coating between anatase nanotubes.
