  1. 26. Electrocatalysts for sustainable hydrogen energy : disordered and heterogeneous nanomaterials

    Författare :Joakim Ekspong; Thomas Wågberg; Ludvig Edman; Tomas Edvinsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Water splitting; Electrochemistry; Nanomaterials; Density functional theory; Hydrogen evolution; MoS2; Fuel cell; nanomaterials; nanomaterial; fysik; Physics; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : With the current global greenhouse gas emissions, our remaining carbon budget is depleted in only 7 years. After that, several biophysical systems are predicted to collapse such as the arctic ice, coral reefs and the permafrost, leading to potentially irreversible consequences. LÄS MER

  3. 27. Atomic Spectroscopy on Fusion Relevant Ions and Studies of Light Impurities in the JET Tokamak

    Författare :Magnus Tunklev; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Active and Passive Charge Exchange; Transport; Diffusion; Convection; Neutral Background Densities; Ion temperatures; Fusion; Isoelectronic sequences; Plasma; Atom- och molekylärfysik; Fysicumarkivet A:1999:Tunklev; Ritz formalism; Plume; Atomic and molecular physics;

    Sammanfattning : The spectrum and energy levels C IV and the 3l4l' system of the Mg-like ions in the iron group elements has been investigated. This has led to several hundred identified transitions, many of them previously unknown. LÄS MER

  4. 28. Use of Aqueous Slurries of Oxides for Ecocompatible Organic Synthesis

    Författare :Zebastian Boström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : There is a continuous interest and need of developing environmentally benign synthetic routes. Increased public awareness and more rigid environmental legislation have elevated the drive towards sustainable development and ecocompatible syntheses. LÄS MER

  5. 29. Role of semiochemical in host finding, oviposition and sexual communication in Guatemalan potato moth Tecia solanivora

    Författare :Miriam Frida Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Semiochemicals are important cues in the interaction between plant and insects and between conspecific insects. Volatile compounds emitted by plants provide herbivorous insects with cues for host finding, selection and discrimination. In moths, female emitted sex pheromones enable conspecific males to find them for mating. LÄS MER

  7. 30. Route attribution of chemical warfare agents : Retrospective classification of unknown threat samples

    Författare :Karin Höjer Holmgren; Johan Dahlén; Crister Åstot; Peter Haglund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Impurity profiling; Chemical attribution signature; Route sourcing;

    Sammanfattning : Although chemical warfare agents (CWAs) are prohibited under international law, there have been numerous crimes that violates the 1997 Chemical Weapons Convention (CWC) during the last decade, especially in the civil war in Syria where sarin, mustard gas and chlorine have all been used. CWAs have also been used in political assassinations and attempts thereof. LÄS MER
