    Fabrication and characterization of Si1−xGex nanocrystals in as-grown and annealed structures: a comparative study 
    Sultan, Muhammad Taha; Maraloiu, Adrian Valentin; Stavarache, Ionel; Gudmundsson, Jon Tomas; Manolescu, Andrei; Teodorescu, Valentin Serban; Ciurea, Magdalena Lidia; Svavarsson, Halldor (Beilstein Institut, 2019-09-17)
    Multilayer structures comprising of SiO2/SiGe/SiO2 and containing SiGe nanoparticles were obtained by depositing SiO2 layers using reactive direct current magnetron sputtering (dcMS), whereas, Si and Ge were co-sputtered using dcMS and high-power impulse ...

    The Influence of Secondary Electron Emission and Electron Reflection on a Capacitively Coupled Oxygen Discharge 
    Proto, Andrea; Gudmundsson, Jon Tomas (MDPI AG, 2018-11-28)
    The one-dimensional object-oriented particle-in-cell Monte Carlo collision code oopd1 is applied to explore the role of secondary electron emission and electron reflection on the properties of the capacitively-coupled oxygen discharge. At low pressure ...

    On singlet metastable states, ion flux and ion energy in single and dual frequency capacitively coupled oxygen discharges 
    Hannesdottir, Holmfridur; Gudmundsson, Jon Tomas (IOP Publishing, 2017-03-27)
    We apply particle-in-cell simulations with Monte Carlo collisions to study the influence of the singlet metastable states on the ion energy distribution in single and dual frequency capacitively coupled oxygen discharges. For this purpose, the ...

    The responses of an anaerobic microorganism, Yersinia intermedia MASE-LG-1 to individual and combined simulated Martian stresses 
    Beblo-Vranesevic, Kristina; Bohmeier, Maria; Perras, Alexandra K.; Schwendner, Petra; Rabbow, Elke; Moissl-Eichinger, Christine; Cockell, Charles S.; Pukall, Rüdiger; Vannier, Pauline; Marteinsson, Viggó; Monaghan, Euan P.; Ehrenfreund, Pascale; Garcia-Descalzo, Laura; Gómez, Felipe; Malki, Moustafa; Amils, Ricardo; Gaboyer, Frédéric; Westall, Frances; Cabezas, Patricia; Walter, Nicolas; Rettberg, Petra (Public Library of Science (PLoS), 2017-10-25)
    The limits of life of aerobic microorganisms are well understood, but the responses of anaerobic microorganisms to individual and combined extreme stressors are less well known. Motivated by an interest in understanding the survivability of anaerobic ...

    Retinal oximetry with a prototype handheld oximeter during hyperoxia 
    Vehmeijer, Wouter B.; Jonkman, Kelly; Harðarson, Sveinn Hákon; Aarts, Leon; Stefánsson, Einar; Dahan, Albert; Schalij-Delfos, Nicoline E. (2021-03-01)
    Purpose: Retinal oximetry measures oxygen saturation in retinal vessels. With the introduction of a mobile handheld prototype oximeter, this technique will become available for a broader patient population including bedridden patients and newborn babies. ...
