Enhancement of Tribological Behavior of ZrCN Coating

Autor: Ángel Fernández, Cristina Zubizarreta, Gemma Mendoza, Aleida Lostalé, Daniel Elduque, Pere Castell, Isabel Clavería

Publikováno v: Proceedings of 1st Coatings and Interfaces Web Conference.

This paper focuses on tribological behavior of ZrCN coating on bearing steel substrates DIN 17230, 100Cr6 / 1.3505, fulfilling also roughness and adherence requirements. Two strategies are followed to achieve a reduction of coefficient of friction. I

Colloidal stability and ecotoxicity of multiwalled carbon nanotubes: Influence of select organic matters

Autor: Gotzone Barandika, Nerea Uranga, Cristina Cerrillo, Olatz Areitioaurtena, Amaya Igartua, Gemma Mendoza

Publikováno v: Environmental Toxicology and Chemistry. 35:74-83

In the last few years, the release of multiwalled carbon nanotubes (MWCNTs) into the environment has raised serious concerns regarding their fate and potential impacts. Aquatic organisms constitute an important pathway for their entrance and transfer
