  1. 1. Bioelectronic Approaches for On-Demand Generation of Reactive Oxygen Species

    Författare :Eva Miglbauer; Eric Glowacki; Oliya Abdullaeva; Lars Peter Nielsen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ROS; ORR; WOR; Fenton reaction; Electrolysis; Bioelectronics;

    Sammanfattning : Reactive oxygen species (ROS) are an integral part of our lives. They perform essential functions in our biology and are, due to their high oxidative power, key molecules in advanced oxidation processes in industrial applications such as treatment of wastewater. LÄS MER

  3. 2. Degenerating Orr-Sommerfeld eigenmodes and development of three-dimensional perturbations

    Författare :Rajaratnam Shanthini; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Degeneracies of temporally damped Orr-Sommerfeld eigenmodes are studied primarily for plane Poiseuille flow. The discrete spectrum of the eigenmodes is shown to possess infinitely many degeneracies, each appearing at a certain combination of k (the modulus of resultant wavenumber) and α R (the streamwise wavenumber times the Reynolds number).
