Deviations from theoretical estimations due to the combined influence of the many‐body and chemical environment effects, overall error in the present measured intensity ratios is estimated to be ~3–5%

P. Papageorgiou, A. G. Karydas, V. Kantarelou, G. Papageorgiou, E. Makarona, Combining bottom-up and top-down approaches with micro X-ray fluorescence spectroscopy for controllable fabrication of periodic ZnO nanostructures, presented at 45th International Conference on Micro & Nano Engineering, Rhodes Greece, September 23rd - 26th, 2019
3-step Fabrication Process combining bottom-up (sol-gel + hydrothermal growth of nanostructures) with top-down fabrication methods (e-beam lithography
Results of μ-XRF can ne used to evaluate non-destructively the uniformity and homogeneity of seeding layer’s nanotopography and can be used to reveal possible correlations to the subsequent lithographic steps and hydrothermal growth of nanostructures
Micro-XRF as non-destructive and enabling nanometrology technique that can leverage the development of novel nanofabrication processes

Biomedicine
K-means clustering and non-negative matrix factorization were applied for image segmentation of acquired elemental distribution maps into three sub-regions corresponding to stromal area, tumour area and unclassified area. Great potential in the investigation on the role of micro and trace elements in tumour biology

Scutiger pes-caprae
Hg in examined mushrooms from non-polluted environments ismainly bound to di-thiolate (43-82%) and di-selenol (13-35%) ligands and less to tetra-thiols (12-20%), while at Hgpolluted sites the proportion of di-selenoland tetra-thiol ligandsincreases

The Challenge (2019-2023)The main aims and objectives of the Action is to coordinate the efforts made at national and transnational level to establish total reflection X-ray fluorescence (TXRF) as a reference technique for reliable elemental analysis of solid and liquid matrices, for the purposes of both fast screening and accurate quantitative determination. These objectives will be achieved via the development of a strong TXRF network, building capacity by training, connecting and involving stakeholders.
StructureThe Managing Committee (MC) decided on the following Working Group (WG) structure for the Action:•WG1 - Instrumentation, modelling, data evaluation and software •WG2 - Metrology and standardization •WG3 - Sample preparation and analytical procedures •WG4 - Performance Assessment and Data Analysis Thematic Sub Groups (SG) are also established:•SG Environment •SG Surfaces and Thin Films •SG Bio-medical Diagnostics
