Post mortem analyses of JET ITER-Like-Wall tiles and passive diagnostics have been completed after each the first two campaigns (ILW-1 ILW-2). They show that global fuel inventory is still dominated by co-deposition; hence plasma parameters sputtering processes affecting material migration influence distribution retained fuel. In particular, differences between results from may be attributed to a greater proportion pulses run with strike points in divertor corners, having about 300...
The work presented draws on new analysis of components removed following the second JET ITER-like wall campaign 2013–14 concentrating upper inner divertor, and outer divertor corners, lifetime issues relating to tungsten coatings carbon fibre composite tiles dust/particulate generation. results show that remains region highest deposition in JET-ILW. Variations plasma configurations between first have altered material migration corners divertor. Net is shown be beneficial sense it reduces W...
Old manuscripts are among the most important elements of cultural and historical heritage ancient knowledge. Unfortunately, many them suffer from degradation, mostly those written with iron gall inks. In present work, a study using non-destructive techniques was designed aim analyzing elemental composition structural characteristics inks, reproduced in laboratory, paper their interaction when ink is deposited on paper, inducing degradation. Proton induced X-ray emission, diffraction...
Abstract An assessment of the tritium (T) inventory in plasma facing components (PFC) during JET T and deuterium-tritium (DT) operations is presented based on most comprehensive ex situ fuel retention data set PFCs from 2015-2016 ILW3 operating period presented. The global 4.19 × 10 23 D atoms, 0.19% injected fuel. inner divertor remains region highest (46.5%). at end calculated as 7.48 22 atoms informative for accountancy, clean-up efficacy waste liability assessments. accumulation rate...
Post-mortem analyses of individual components provide relevant information on plasma-surface interactions like tungsten erosion, beryllium deposition and plasma fuel retention with divertor tiles via implantation or co-deposition. Ion Beam techniques are ideal tools for such purposes have been extensively used post-mortem selected from JET following each campaign. In this contribution results removed the ITER-Like Wall (JET-ILW) 2013–2014 campaign presented. The summarize along poloidal...
Post mortem analysis shows that mid and high atomic number metallic impurities are present in deposits on JET plasma facing components with the highest amount of Ni W, therefore largest sink, being found at top inner divertor. Sources defined as "continuous" or "specific", sources arise from ongoing erosion surfaces "specific" linked specific events which decrease over time until they no longer act a source. This contribution evaluates sinks estimates sources, balance gives an indication...
The control of morphology and crystallinity solution-processed perovskite thin-films for solar cells is the key further enhancement devices' power conversion efficiency stability. Improving increasing grain size films a proven way to boost performance operational robustness, nevertheless this has only been achieved with high-temperature processes. Here, we present an unprecedented low-temperature (<80 °C) ultrafast microwave (MW) annealing process yield uniform, compact, crystalline...
Abstract A comparative study of four different metals gold (Au), platinum (Pt), ruthenium (Ru) and rhodium (Rh) deposited on CdZnTe(CZT) by the electroless deposition method has been carried out. Two these materials, Ru Rh, have for first time this method. In contrast to Pt deposition, Rh were not out under optimal conditions. The samples identified Total reflection X‐ray Fluorescence (TXRF). Rutherford Backscattering Spectrometry (RBS) analyses show that Au forms thickest layer (∼160 nm)...
Abstract The influence of deposition methods and type metal contacts on the defects generated at metal/semiconductor interface has been investigated. Photoluminesccence spectra a low temperature demonstrated that Au electroless samples exhibit lowest I (D 0 ,X) / A-center ratio have best gamma response. Rutherford backscattering spectrometry results show sputtering method creates highest concentration TeO 2 layer compared with evaporation methods. more inter-diffusion between contact CZT...
The colour of the layer-by-layer film developed on Ag–Cu alloys in sulphide environments varies with its thickness and composition.
Continuous advancements in understanding and controlling surface functionalisation properties empower materials scientists to design with tailored characteristics, improved performance, enhanced functionality, thereby expanding scientific knowledge technological progress. This research paper presents the synthesis of two new metal-organic material-based films using cathodic electrodeposition method. In contrast anodic deposition method, method offers advantage non-metal electrode substrates...
