The provision of a particle and power exhaust solution which is compatible with first-wall components edge-plasma conditions key area present-day fusion research mandatory for successful operation ITER DEMO. work package plasma-facing (WP PFC) within the European programme complements laboratory experiments, i.e. in linear plasma devices, electron ion beam loading facilities, studies performed toroidally confined magnetic such as JET, ASDEX Upgrade, WEST etc. connection both groups done via...
Nano zero-valent iron (nZVI) has great potential in the remediation of metal(loid)-contaminated soils, but its efficiency metal(loid) stabilization plant-microbe continuum is unclear. This study investigated nZVI-mediated behavior arbuscular mycorrhizal (AM) fungal-maize ( Zea mays L.) plant association. Plants with AM fungal inoculation were grown metal(loid)- (mainly Zn and Pb) contaminated soils (Litavka River, Czech Republic) amended with/without 0.5% (w/w) nZVI. The results showed that...
Abstract Cross denars, frequently found in Polish hoards, were traditionally thought to be Ag coins with some Cu content. This study investigates the possibility of a hidden core beneath or Ag–Cu surface these coins. It raises questions about whether they counterfeits intentionally designed for mass production. Unlike Roman denarii, which revealed their cores when broken, examination cross denars without damage is challenging. Optical microscopy and microanalysis differences composition...
Polycrystalline tungsten (W) samples were simultaneously irradiated by 10.8 MeV W ions and exposed to 300 eV deuterium (D) at different temperatures ranging from 450 K 1000 K. After simultaneous ion irradiation D exposure the additionally low-energy in order populate all defects created beforehand. The amount of damage was evaluated measuring depth profiles thermal desorption spectra. Results compared with data obtained a sequential experiment where first only afterwards defects. At we...
Deuterium retention was for the first time measured in tungsten samples simultaneously irradiated by W ions and exposed to D atoms at five different temperatures from 450 K 1000 K. In order obtain information on defect concentration, were afterwards 600 populate created defects. The results compared sequential damaging/exposure experiments. Synergistic effects observed, namely, higher concentrations found case of simultaneous damaging D-atom loading as elevated populating defects afterwards....
Gross and net erosion of tungsten (W) other plasma-facing materials in the divertor region have been investigated deuterium (D) helium (He) plasmas during dedicated experiments L- H-mode on ASDEX Upgrade after full-length experimental campaigns WEST tokamak. Net was determined via post-exposure analyses plasma-exposed samples full-size wall components, we conclude that same approach is applicable to gross if marker structures with sub-millimeter dimensions are used eliminate contribution...
Porous tantalum has been extensively used in orthopaedic surgery, including uncemented total knee arthroplasty (TKA). Favourable results were reported with earlier monobloc tibial components and the design evolved to modular implants. We aimed analyse possible causes for extensive medial tibia bone loss, resulting porous baseplate fracture after primary TKA. Retrieved tissue samples scanned 3 MeV focused proton beam Proton-Induced X-ray Emission (micro-PIXE) elemental analysis. Fractographic...
The influence of grain boundaries on deuterium (D) retention and transport was investigated in nanocrystalline tungsten (W) by exposing the samples to sub eV D atoms. Thin films with nanometer-sized grains were produced pulsed laser deposition substrates. Their size increased up one micrometer thermal annealing vacuum 1223 K. Irradiation damage created 20 MeV W ions at 290 transmission electron microscopy analysis showed order magnitude larger dislocation density nanometer-grained compared...

Abstract Background Phosphorus (P) deficiency limits crop production worldwide. Crops differ in their ability to acquire and utilise the P available. The aim of this study was determine root traits (root exudates, system architecture (RSA), tissue-specific allocation P, gene expression roots) that (a) play a role P-use efficiency (b) contribute large shoot zinc (Zn) concentration Brassica oleracea . Results Two B. accessions (var. sabellica C6, kale, var. italica F103, broccoli) were grown...
Radiation-induced defect production in tungsten was studied by a combination of experimental and simulation methods. The analysis structural defects performed using multi-energy Rutherford backscattering spectroscopy channeling configuration (multi-energy C-RBS). To create different microstructures, (111) (W) single crystals were irradiated with W ions at two doses (0.02 0.2 dpa) 290 K. Detailed transmission electron microscopy (TEM) the samples revealed presence dislocation lines loops...
The effect of deuterium (D) on the annealing radiation damage was studied. Tungsten (W) samples were sequentially irradiated with 20 MeV W ions at room temperature and loaded a low-temperature D plasma 370 K to decorate created defects. After this, half each sample again create additional damage. To study evolution defects being present, annealed by heating them desired held for 2 h. surviving displacement decorated re-exposing same as before. At various steps experiment depth profiles...
Magnesium (Mg) and calcium (Ca) are essential mineral nutrients poorly supplied in many human food systems. In grazing livestock, Mg Ca deficiencies costly welfare issues. Here, we report a Brassica rapa loss-of-function schengen3 (sgn3) mutant, braA.sgn3.a-1, which accumulates twice as much third more its leaves. We mapped braA.sgn3.a to single recessive locus using forward ionomic screen of chemically mutagenized lines with subsequent backcrossing linked-read sequencing second...
Element profile signatures of needle tissues differentiated four tissues: epidermis (main contributor: calcium), endodermis contributors: magnesium, sulphur and manganese), mesophyll potassium), transfusion parenchyma zinc). Distribution elements in cross-sections Scots pine (Pinus sylvestris L.) needles was investigated using micro-proton-induced X-ray emission. Tissue-specific distributions magnesium (Mg), (S), calcium (Ca), phosphorus (P), potassium (K), chlorine (Cl), manganese (Mn),...
