      Barja Martínez, Sara ORCID; Refaely Abramson, Sivan; Schuler, Bruno; Qiu, Diana Y.; Pulkin, Artem; Wickenburg, Sebastian; Ryu, Hyejin; Moreno Ugeda, Miguel; Kastl, Christoph; Chen, Christopher; Hwang, Choongyu; Schwartzberg, Adam; Aloni, Shaul; Mo, Sung-Kwan; Ogletree, D. Frank; Crommie, Michael F.; Yazyev, Oleg V.; Louie, Steven G.; Neaton, Jeffrey B.; Weber-Bargioni, Alexander (Nature, 2019-07-29)
      Chalcogen vacancies are generally considered to be the most common point defects in transition metal dichalcogenide (TMD) semiconductors because of their low formation energy in vacuum and their frequent observation in ...

      Sustainable oxygen evolution electrocatalysis in aqueous 1 M H2SO4 with earth abundant nanostructured Co3O4 

      Yu, Jiahao; Garcés Pineda, Felipe A.; González Cobos, Jesús; Peña Díaz, Marina; Rogero Blanco, Celia; Giménez, Sixto; Spadaro, Maria Chiara; Arbiol, Jordi; Barja Martínez, Sara ORCID; Galán Mascarós, José Ramón (Nature, 2022)
      Earth-abundant electrocatalysts for the oxygen evolution reaction (OER) able to work in acidic working conditions are elusive. While many first-row transition metal oxides are competitive in alkaline media, most of them ...
