  1. 1. Single layer near-field acoustic imaging in space-invariant reflective environments

    Author : Elias Zea; Ines Lopez Arteaga; Efren Fernandez-Grande; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; near-field acoustic holography; field separation techniques; single layer; space-invariance; reflective envirionments; närfält akustisk holografi; fältseparationstekniker; enkelt lager; utrymmes invarians; reflekterande miljöer; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The visualization of optical fields, or widely known as photography, is a common practice that can also be applied to acoustic fields. No less than three decades of research in acoustic imaging demonstrate its potential and relevance in plenty applications such as sound source identification and localization, as well as characterization of noise generation mechanisms.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enhanced near-field; adsorption; titanium dioxide; Localized Surface Plasmon Resonance; amorphous hydrogenated Silicon; diffusion; Langmuir kinetics; Dye-Sensitized Solar Cell; plasmonic nanoparticle; mesoporous material; diffusion-front model;

    Abstract : The main source of our energy system, the fossil fuels, will eventually be depleted and also pose environmental and climate hazards. There is thus a need for alternative, renewable energy sources. Solar (photovoltaic) cells will play an important role as one of them. READ MORE

  4. 4. Nanoplasmonic Enhancement of Photon-to-Electron Conversion in Functionalized Iron Oxide Photoanodes

    Author : Beniamino Iandolo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Photon-to-Electron Conversion; Hydrogen; Near-field Enhancement; Iron Oxide; Nanoparticles; Localized Plasmons; Water Splitting;

    Abstract : The ever increasing energy demand of modern society clashes with the accelerating depletion of the fossil fuels from which most of this energy is taken today. Moreover, fossil fuels consumption poses a severe threat on the Earth’s environment and climate through global warming. READ MORE

  5. 5. Photoelectrochemical Processes on Fe2O3 Based Model Anodes

    Author : Beniamino Iandolo; Chalmers tekniska högskola; []

    Abstract : One possibility to partially satisfy the ever-increasing energy needs of modern society, without compromising the Earth’s environment through e.g. global warming, consists in harvesting solar energy and storing it as hydrogen produced from water splitting. This can potentially be achieved on a large scale using photoelectrochemical (PEC) cells. READ MORE
