Journal ArticleDOI
The Chemistry of the Sulfur–Gold Interface: In Search of a Unified Model
Evangelina Laura Pensa,Emiliano Cortés,Gastón Corthey,Pilar Carro,Carolina Vericat,Mariano H. Fonticelli,Guillermo Benítez,Aldo A. Rubert,Roberto Carlos Salvarezza +8 more
TL;DR: A state-of-the-art analysis of the structure and chemical composition of the sulfur-gold interface at the atomic level remains elusive and the search for a unified model of the chemistry of the S-Au interface illustrates the difficulty of determining the surface chemistry at the nanoscale.
Journal ArticleDOI
Self-assembled monolayers of thiolates on metals: A review article on sulfur-metal chemistry and surface structures
Carolina Vericat,María Elena Vela,Gastón Corthey,Evangelina Laura Pensa,Emiliano Cortés,Mariano H. Fonticelli,Francisco J. Ibañez,Guillermo Benítez,Pilar Carro,Roberto Carlos Salvarezza +9 more
TL;DR: A review article on fundamental aspects of thiolate self-assembled monolayers (SAMs) on the (111 and 100) surfaces of the Cu and Ni groups is presented in this article.
Journal ArticleDOI
Spectral Screening of the Energy of Hot Holes over a Particle Plasmon Resonance
Evangelina Laura Pensa,Julian Gargiulo,Alberto Lauri,Sebastian Schlücker,Emiliano Cortés,Emiliano Cortés,Stefan A. Maier,Stefan A. Maier +7 more
TL;DR: It is shown that plasmon excitation reduces the energy required to start the polymerization reaction as much as 0.24 eV, and this last phenomenon is found to be the one contributing most prominently to the observed energy reduction.
Journal ArticleDOI
Understanding the Surface Chemistry of Thiolate-Protected Metallic Nanoparticles
Julio C. Azcárate,Gastón Corthey,Evangelina Laura Pensa,Carolina Vericat,Mariano H. Fonticelli,Roberto Carlos Salvarezza,Pilar Carro +6 more
TL;DR: In this article, the complexity of the thiol-metal NP interface chemistry and how this changes with the nature of the metallic core is discussed. And the most common strategy to protect these NPs is by using thiolate self-assembled monolayers, a strategy that has proved to be useful to control the physical and chemical properties of extended solid surfaces.
Journal ArticleDOI
Anapole Excitations in Oxygen-Vacancy-Rich TiO2-x Nanoresonators: Tuning the Absorption for Photocatalysis in the Visible Spectrum.
Ludwig Hüttenhofer,Felix Eckmann,Alberto Lauri,Javier Cambiasso,Evangelina Laura Pensa,Yi Li,Yi Li,Emiliano Cortés,Ian D. Sharp,Stefan A. Maier,Stefan A. Maier +10 more
TL;DR: It is shown that by varying the nanodisk geometry, the anapole wavelength is shifted into resonance with optical transitions associated with the sub-bandgap oxygen vacancy states and thereby increase visible light absorption.
