Gold-assisted molecular imaging of organic tissue by MeV secondary ion mass spectrometry
Boštjan Jenčič, Paula Pongrac, Mirjana Vasić, Pia Starič, Mitja Kelemen, Marjana Regvar
Izvirni znanstveni članek
Oznake: molecular imaging;organic tissue;secondary ion mass spectrometry;
The quality of molecular imaging by means of MeV primary ion-induced secondary ion mass spectrometry by coating with gold was evaluated on different reference organic molecules and plant samples. The enhancement of the secondary ion yield was evident for the majority of the studied analytes, reachin ...

Influence of near-surface helium on the deuterium retention and uptake in tungsten
Sabina Markelj, Thomas Schwarz-Selinger, Andreja Šestan, Janez Zavašnik, Mitja Kelemen
Izvirni znanstveni članek
Oznake: deuterium retention;displacement damage;
The effect of near-surface helium (He) on deuterium (D) retention and uptake into the bulk of tungsten (W) was investigated. To quantify the He influence on D uptake, He was implanted close to the surface with 3 keV energy at different fluences and different temperatures. 20 MeV W irradiation was pe ...

Unveiling the radiation-induced defect production and damage evolution in tungsten using multi-energy Rutherford backscattering spectroscopy in channeling configuration
Sabina Markelj, Janez Zavašnik, Esther Punzón Quijorna, Andreja Šestan, Mitja Kelemen
Izvirni znanstveni članek
Oznake: presevna elektronska mikroskopija;tungsten;defects;Rutherford backscattering spectroscopy in channeling configuration;displacement damage;molecular dynamic simulations;transmission electron microscopy;
Radiation-induced defect production in tungsten was studied by a combination of experimental and simulation methods. The analysis of structural defects was performed using multi-energy Rutherford backscattering spectroscopy in channeling configuration (multi-energy C-RBS). To create different micros ...

On the distribution and evaluation of Na, Mg and Cl in leaves of selected halophytes
Paula Pongrac, Katarina Vogel-Mikuš, Marjana Regvar, Mitja Kaligarič, Primož Vavpetič, Mitja Kelemen, Nataša Grlj, Primož Pelicon
Izvirni znanstveni članek
Oznake: light elements;micro-PIXE;salinity;salt tolerance;
Diverse physiological, biochemical and morphological adaptations enable plantsto survive in extreme saline environments where osmotic and ionic stresses limit growth and development. Halophytes are salt-tolerant plants that can withstand extraordinarily high levels of Na and Cl in their leaves. The ...

Exploring the potential of cold plasma treatment followed by zinc-priming for biofortification of buckwheat sprouts
Pia Starič, Lucija Remic, Katarina Vogel-Mikuš, Ita Junkar, Primož Vavpetič, Mitja Kelemen, Paula Pongrac
Izvirni znanstveni članek
Oznake: Fagopyrum esculentum;common buckwheat;non-thermal plasma;zinc distribution;grain tissues;
Increasing the concentration of an element in edible produce (i.e., biofortification) can mitigate the element deficiency in humans. Sprouts are small but popular part of healthy diets providing vitamins and essential elements throughout the year. Element composition of sprouts can easily be amended ...
