  2. 1. In Rhizomia : Actors, Networks and Resilience in Urban Landscapes

    Author : Henrik Ernstson; Thomas Elmqvist; Sverker Sörlin; Erik Swyngedouw; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban ecosystem services; green space; social network analysis; social movements; actor-networks; transformation; ecosystem management; scale mismatch; co-management; governance; broker; conservation; Stockholm; Human ecology; Humanekologi; Natural Resources Management; naturresurshushållning;

    Abstract : With accelerating urbanization it is crucial to understand how urban ecosystems play a part in generating ecosystem services for urban dwellers, such as clean water, spaces for recreation, stress relief and improved air quality. An equally important question relate to who gets to enjoy these benefits, i.e. READ MORE

  4. 2. Catalytic Water Production from First-Principles Calculations

    Author : Gustav Karlberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; platinum; Monte Carlo; first-principles; hydroxyl; transition metals; density functional theory DFT ; Metropolis; oxygen; water; water production reaction; hydrogen;

    Abstract : The main subject of this thesis is the catalytic water production reaction on metal surfaces. This reaction is of great current interest due to its importance in fuel cells, a clean and efficient way to convert chemical energy into electrical. READ MORE

  5. 3. Water oxidation : From Molecular Systems to Functional Devices

    Author : Quentin Daniel; Licheng Sun; Marc Robert; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water oxidation; Renewable energy; Electrochemistry; EPR; Devices; Molecular system; Characterization; Kemi; Chemistry;

    Abstract : The production of hydrogen gas, through the process of water splitting,is one of the most promising concepts for the production of clean andrenewable fuel.The introduction of this thesis provides a brief overview of fossil fuelsand the need for an energy transition towards clean and renewable energy.

  6. 4. Exploring the role of granular activated carbon in drinking water production

    Author : Malin Ullberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Safe and clean drinking water is recognised as a human right by the United Nations, but water sources world-wide are affected by the widespread use of synthetic chemicals, creating a challenge that drinking water producers must address. Many of these synthetic chemicals, here referred to as organic micropollutants (OMPs), are not well removed by conventional drinking water treatment, and thus additional treatment steps are needed.

  7. 5. Water-Metal Surfaces : Insights from core-level spectroscopy and density functional theory

    Author : Theanne Schiros; Anders Nilsson; John Hemminger; Stockholms universitet; []
    Keywords : water; hydroxyl; metal; surfaces; x-ray spectroscopy; density functional theory; bonding; fuel cell; kemisk fysik; Chemical Physics;

    Abstract : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. READ MORE
