Journal ArticleDOI
Hot Electrons Do the Impossible: Plasmon-Induced Dissociation of H2 on Au
Shaunak Mukherjee,Florian Libisch,Nicolas Large,Oara Neumann,Lisa V. Brown,Jin Cheng,J. Britt Lassiter,Emily A. Carter,Peter Nordlander,Naomi J. Halas +9 more
TL;DR: The room temperature dissociation of H(2) on gold nanoparticles using visible light is reported to open a new pathway for controlling chemical reactions on metallic catalysts.
Journal ArticleDOI
Solar Vapor Generation Enabled by Nanoparticles
TL;DR: Solar illumination of broadly absorbing metal or carbon nanoparticles dispersed in a liquid produces vapor without the requirement of heating the fluid volume, enabling important compact solar applications such as sterilization of waste and surgical instruments in resource-poor locations.
Journal ArticleDOI
Plexcitonic nanoparticles: plasmon-exciton coupling in nanoshell-J-aggregate complexes.
TL;DR: From a model based on Gans theory, an expression for the plasmon-exciton hybridized states of the complex is obtained.
Journal ArticleDOI
Evolution of light-induced vapor generation at a liquid-immersed metallic nanoparticle
Zheyu Fang,Yu-Rong Zhen,Oara Neumann,Albert Polman,F. Javier García de Abajo,Peter Nordlander,Naomi J. Halas +6 more
TL;DR: These studies provide the first direct and quantitative analysis of the evolution of light-induced steam generation by nanoparticles from the nanoscale to the macroscale, a process that is of fundamental interest for a growing number of applications.
Journal ArticleDOI
Compact solar autoclave based on steam generation using broadband light-harvesting nanoparticles
Oara Neumann,Curtis Feronti,Albert D. Neumann,Anjie Dong,Kevin Schell,Benjamin Y. Lu,Eric S. Kim,Mary K. Quinn,Shea Thompson,Nathaniel K. Grady,Peter Nordlander,Maria Oden,Naomi J. Halas +12 more
TL;DR: The use of broadband light-absorbing nanoparticles as solar photothermal heaters, which generate high-temperature steam for a standalone, efficient solar autoclave useful for sanitation of instruments or materials in resource-limited, remote locations, is shown.
