Enhanced hydrogen production from water via a photo-catalyzed reaction using chalcogenide d-element nanoparticles induced by UV light.

Hydrogen has the potential to meet the requirements as a clean non-fossil fuel in the future. The photocatalytic production of H2 through water splitting has been demonstrated and enormous efforts have been published. The present work is an attempt to enhance the production of H2 during water splitting using synthesized nanoparticles based on chalcogenide d-element semiconductors via a photochemical reaction under UV-light in the presence of methanol as a hole-scavenger.

Mitro-aortic infective endocarditis produced by Erysipelothrix rhusiopathiae: case report and review of the literature.

Endocarditis produced by Erysipelothrix rhusiopathiae is an uncommon disease in humans. This bacterial species is found worldwide as a commensal or a pathogen in many animals. Infection in humans is usually due to occupational exposure.
