  1. 16. Nanoplasmonic Alloy Hydrogen Sensors

    Författare :Ferry Nugroho; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indirect nanoplasmonic sensing; plasmonic sensors; hydrogen sensors; polymers; fiber optics; nanofabrication; localized surface plasmon resonance; alloy nanoparticles; carbon capture and storage; sensors; palladium;

    Sammanfattning : The hydrogen economy proposes hydrogen gas as the main energy carrier thanks to its high energy density and the possibility to produce it in a sustainable way without CO2 emission. However, the wide flammability range of hydrogen-air mixtures dictates that hydrogen sensors will be a mandatory accessory to any appliance or vehicle fueled by hydrogen. LÄS MER

  3. 17. Monitoring insect defoliation in forests with time-series of satellite based remote sensing data - near real-time methods and impact on the carbon balance

    Författare :Per-Ola Olsson; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Forests are of major importance to climate change mitigation due to their strong capacity to sequester carbon. Nearly half of the terrestrial carbon is stored in forests, and forests contribute to half of the terrestrial primary productivity, with forests in the mid- and high latitude ecosystems as major contributors.

  4. 18. Microsystems for Harsh Environments

    Författare :Stefan Knaust; Lena Klintberg; Klas Hjort; Fredric Ericson; Samuel Marre; Uppsala universitet; []
    Nyckelord :Microsystems; harsh environments; high pressures; high temperatures; supercritical microfluidics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : When operating microsystems in harsh environments, many conventionally used techniques are limiting. Further, depending on if the demands arise from the environment or the conditions inside the system, different approaches have to be used. LÄS MER

  5. 19. Continuously tunable narrow-linewidth fiber lasers

    Författare :Xiong Yang; Valdas Pasiskevicius; Fredrik Laurell; Magnus Engholm; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber laser; Optik och fotonik; Optics and Photonics;

    Sammanfattning : Narrow linewidth tunable fiber lasers have become an important tool in research and in-field applications thanks to their high beam quality, great spectral performance, compact structure and environmental robustness. Many methods have been introduced and developed throughout decades to fulfill the need for rapid wavelength adjustment of these fiber lasers. LÄS MER

  7. 20. Solving Analytical Challenges with Thin Layer Electrochemistry

    Författare :Alexander Wiorek; Gaston A. Crespo; Maria Cuartero; Gregoire Herzog; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Thin Layer Electrochemistry; Polyaniline; Carbon nanotubes; Ion-selective electrodes; Ionophores; Electrochemical Sensors; Alkalinity; Deionization; Chemical Imaging; Tunnskiktselektrokemi; polyanilin; kolnanorör; jonselektiva elektroder; jonoforer; elektrokemiska sensorer; Alkalinitet; avjonisering; chemical imaging; Kemi; Chemistry;

    Sammanfattning : The decentralization of chemical sensing to attain environmental-related information is today highly desirable to increase the knowledge on biological or geological events as well as effluents. The current state of the field moves toward submersible probes; chemical sensors implemented into submersible devices for quantifying analytes over extended times. LÄS MER
