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

    Författare :Beniamino Iandolo; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 22. Photoelectrochemical Processes on Fe2O3 Based Model Anodes

    Författare :Beniamino Iandolo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Near- field Enhancement; Hydrogen; Hematite; Water Splitting; Flatband Potential; Surface States.; Localized Plasmons; Nanoparticles;

    Sammanfattning : 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. LÄS MER

  4. 23. Modelling Charge Transport for Organic Solar Cells within Marcus Theory

    Författare :Riccardo Volpi; Mathieu Linares; David Huang; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With the technological advancement of modern society, electronic devices are getting progressively more integrated in our everyday lives. Their continuouslygrowing presence is generating numerous concerns about costs, efficiency and the environmental impact of the electronic waste. LÄS MER

  5. 24. Active Matter in a Critical State: From passive building blocks to active molecules, engines, and active droplets

    Författare :Falko Schmidt; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; active matter; nonequilibrium; self-assembly; microswimmers; nanomotors; optical tweezers; colloidal molecules; active droplets; critical Casimir forces;

    Sammanfattning : The motion of microscopic objects is strongly affected by their surrounding environment. In quiescent liquids, motion is reduced to random fluctuations known as Brownian motion. Nevertheless, microorganisms have been able to develop mechanisms to generate active motion. LÄS MER

  7. 25. Sustainable Urban and Regional Development and Related Ecosystem Services and Water-Climate Interactions

    Författare :Jessica Faye Page; Zahra Kalantari; Georgia Destouni; Bev Wilson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; urban planning; regional planning; sustainable cities; nature-based solutions; climate change; planning support systems; sustainable development; naturgeografi; Physical Geography;

    Sammanfattning : To accommodate a growing global population while mitigating climate change, urban areas must grow while minimising environmental impacts. To achieve this, a city must be treated as a complex socio-ecological system in which many actors and subsystems act in unclear and unpredictable ways. LÄS MER
